The HTML for jqueryUI tabs.
<div id="lodg_tabs" class="tabs">
<ul>
<li>Add/Remove</li>
<li>Update</li>
</ul>
<div id="tabs-1" class="forms">
<h3 align="center">Mandate Lodgment</h3>
<form name="mand_lodg" id="mand_lodg" method="post">
ajax code to send parameters to the tab loading "mand_lodg_upd.aspx"
$("#lodg_tabs").tabs({
select: function (event, ui) {
var res = valid('mand_lodg');
$(this).tabs("option", { ajaxOptions: { data: $("#mand_lodg").serialize()} });
},
ajaxOptions: {
type: 'POST',
error: function (xhr, status, index, anchor) {
$(anchor.hash).html("An error has been encountered while attempting to load this tab.");
}
},
cache: false
});
the c# code behind
Response.Write(Request.Form["zone"] + Request.QueryString["zone"]);
zone.Value = Request.Form["zone"];
loc.Value = Request.Form["loc"];
date.Value = Request.Form["date"];
The output: Output is ok, the file is loading in the tab
The problem : but the parameters passed with ajax i.e
$(this).tabs("option", { ajaxOptions: { data: $("#mand_lodg").serialize()} });
zone location and date are null in c# code behind
Request.Form is referring to HTTP request parameters via the POST method. JQuery by default issues a GET method request. Try setting your AJAX Options like so:
$(this).tabs("option", {
ajaxOptions: {
type: 'post',
data: $("#mand_lodg").serialize()
}
});

I have sample code like this:
<div class="cart">
<a onclick="addToCart('#Model.productId');" class="button"><span>Add to Cart</span></a>
</div>
<div class="wishlist">
<a onclick="addToWishList('#Model.productId');">Add to Wish List</a>
</div>
<div class="compare">
<a onclick="addToCompare('#Model.productId');">Add to Compare</a>
</div>
How can I write JavaScript code to call the controller action method?
Use jQuery ajax:
function AddToCart(id)
{
$.ajax({
url: 'urlToController',
data: { id: id }
}).done(function() {
alert('Added');
});
}
http://api.jquery.com/jQuery.ajax/
Simply call your Action Method by using Javascript as shown below:
var id = model.Id; //if you want to pass an Id parameter
window.location.href = '#Url.Action("Action", "Controller")/' + id;
You are calling the addToCart method and passing the product id. Now you may use jQuery ajax to pass that data to your server side action method.d
jQuery post is the short version of jQuery ajax.
function addToCart(id)
{
$.post('#Url.Action("Add","Cart")',{id:id } function(data) {
//do whatever with the result.
});
}
If you want more options like success callbacks and error handling, use jQuery ajax,
function addToCart(id)
{
$.ajax({
url: '#Url.Action("Add","Cart")',
data: { id: id },
success: function(data){
//call is successfully completed and we got result in data
},
error:function (xhr, ajaxOptions, thrownError){
//some errror, some show err msg to user and log the error
alert(xhr.responseText);
}
});
}
When making ajax calls, I strongly recommend using the Html helper method such as Url.Action to generate the path to your action methods.
This will work if your code is in a razor view because Url.Action will be executed by razor at server side and that c# expression will be replaced with the correct relative path. But if you are using your jQuery code in your external js file, You may consider the approach mentioned in this answer.
If you do not need much customization and seek for simpleness, you can do it with built-in way - AjaxExtensions.ActionLink method.
<div class="cart">
#Ajax.ActionLink("Add To Cart", "AddToCart", new { productId = Model.productId }, new AjaxOptions() { HttpMethod = "Post" });
</div>
That MSDN link is must-read for all the possible overloads of this method and parameters of AjaxOptions class. Actually, you can use confirmation, change http method, set OnSuccess and OnFailure clients scripts and so on
If you want to call an action from your JavaScript, one way is to embed your JavaScript code, inside your view (.cshtml file for example), and then, use Razor, to create a URL of that action:
$(function(){
$('#sampleDiv').click(function(){
/*
While this code is JavaScript, but because it's embedded inside
a cshtml file, we can use Razor, and create the URL of the action
Don't forget to add '' around the url because it has to become a
valid string in the final webpage
*/
var url = '#Url.Action("ActionName", "Controller")';
});
});
Javascript Function
function AddToCart(id) {
$.ajax({
url: '#Url.Action("AddToCart", "ControllerName")',
type: 'GET',
dataType: 'json',
cache: false,
data: { 'id': id },
success: function (results) {
alert(results)
},
error: function () {
alert('Error occured');
}
});
}
Controller Method to call
[HttpGet]
public JsonResult AddToCart(string id)
{
string newId = id;
return Json(newId, JsonRequestBehavior.AllowGet);
}
You can simply add this when you are using same controller to redirect
var url = "YourActionName?parameterName=" + parameterValue;
window.location.href = url;
You can set up your element with
value="#model.productId"
and
onclick= addToWishList(this.value);
I am using this way, and worked perfectly:
//call controller funcntion from js
function insertDB(username,phone,email,code,filename) {
var formdata = new FormData(); //FormData object
//Iterating through each files selected in fileInput
formdata.append("username", username);
formdata.append("phone", phone);
formdata.append("email", email);
formdata.append("code", code);
formdata.append("filename", filename);
//Creating an XMLHttpRequest and sending
var xhr = new XMLHttpRequest();
xhr.open('POST', '/Home/InsertToDB');//controller/action
xhr.send(formdata);
xhr.onreadystatechange = function () {
if (xhr.readyState == 4 && xhr.status == 200) {
//if success
}
}
}
in Controller:
public void InsertToDB(string username, string phone, string email, string code, string filename)
{
//this.resumeRepository.Entity.Create(
// new Resume
// {
// }
// );
var resume_results = Request.Form.Keys;
resume_results.Add("");
}
you can find the keys (Request.Form.Keys), or use it directly from parameters.
You can easily make a <a> link in your view.
<a hidden asp-controller="Home" asp-action="Privacy" id="link"></a>
then in you javascript code use this:
location.href = document.getElementById('link').href;
I am running Asp.Net Core 3.1 application where i have one left side menu in layout which i load through partial view.
To set menu link i used the anchor tag like below:
var allRouteData = new Dictionary<string, string>
{
{ "menuid", mID.ToString() },
{ "isCalledByMenu", "true" },
{ "where", "tab" }
};
<a class="#clas" data-ajax="true" data-ajax-complete="RedirectToPage('#M.MenuUrl', '#M.MenuName',true)" data-ajax-mode="replace" data-ajax-update="#myTab" asp-action="GetSubMenu" asp-controller="Base" asp-all-route-data="#allRouteData">#M.MenuName</a>
So when page loads then HTML generate like below:
<a class="nav-link btn fuse-ripple-ready" data-ajax="true" data-ajax-complete="RedirectToPage('/OrgOverview/ProfessionalServices', 'Professional Services',true)" data-ajax-mode="replace" data-ajax-update="#myTab" href="/Base/GetSubMenu?menuid=9630&isCalledByMenu=true&where=tab">Professional Services</a>
Below is action method used :
public IActionResult GetSubMenu(int menuid, bool? isCalledByMenu, string where = null)
{
return ViewComponent("SubMenu", new { menuid = menuid, isCalledByMenu = isCalledByMenu, where = where });
}
In Layout page on the top i assigned the tag helper:
#addTagHelper *, Microsoft.AspNetCore.Mvc.TagHelpers
But when i click on the link it is not hitting this action method.
Update: When i click menu then first it hit the list inside javascript where i do some ajax call:
$('#myTab>li>a.nav-link.btn.fuse-ripple-ready').on("click", function (e) {
e.preventDefault();
var requestedPage = $(this).text();
SetCurrentPageNameSession(requestedPage, false);// ajax call to set some value.
return true;
});
In SetCurrentPageNameSession method i do ajax call to set the menu name in server side to some session before calling action method.
like below:
function SetCurrentPageNameSession(CurrentPage, IsBookMark) {
if (IsBookMark==undefined)
IsBookMark = false;
var url = baseUrl+"Manage/HighlightCurrentMenu/"
$.ajax({
type: "POST",
data: { CurrentPage: CurrentPage, IsBookMark: IsBookMark },
url: url,
dataType: "json",
async:false,
success: function (data) {
var res = data.d;
},
error: function (xhr, ajaxOptions, thrownError) {
}
});
}
Then after it anchor tag call the action method.
Please suggest.
Maybe you could forget data-ajax, it also doesn't work on me and I can't find the answer about it. You could code as below and it also can request the GetSubMenu and continue to excute next logic.
<div id="myTab"></div>
<a class="nav-link btn fuse-ripple-ready"
href="#">Professional Services</a>
<script>
$('a.nav-link.btn.fuse-ripple-ready').on("click", function (e) {
//e.preventDefault();
$.ajax({
url: "/Base/GetSubMenu",
async: true,
type: "get",
datatype: "json",
data: #Json.Serialize(allRouteData),
success: function (result) {
$('#myTab').html(result)
}
});
//RedirectToPage('/OrgOverview/ProfessionalServices', 'Professional Services', true);
var requestedPage = $(this).text();
SetCurrentPageNameSession(requestedPage, false);// ajax call to set some value.
return true;
});
</script>
Comment or Remove e.preventDefault();
Calling preventDefault() during any stage of event flow cancels the event, meaning that any default action normally taken by the implementation as a result of the event will not occur.
I found the solution for the above asked question:
The issue was when i click on menu link then i used to call first it's anchor click in javascript where i did e.preventDefault() and then used to do some ajax call to pass some value to set in session. Due to e.preventDefault() call after that it was not hitting the action method.
Since i had to pass other three data to server to set somewhere. To do that i set all three value in anchor tag data-link attribute separated with Pipe like below:
data-link="9630|true|tab|/OrgOverview/ProfessionalServices|Professional Services"
function SetCurrentPageNameSession(CurrentPage, IsBookMark, MenuID, IsCalledByMenu, Where, PageUrl, PageName) {
var url = baseUrl+"Manage/HighlightCurrentMenu/"
$.ajax({
type: "POST",
data: { CurrentPage: CurrentPage, IsBookMark: IsBookMark, menuID: MenuID, isCalledByMenu: IsCalledByMenu, where: Where},
url: url,
dataType: "json",
async:false,
success: function (data) {
var res = data.d;
if (PageUrl != undefined && PageUrl != '' && PageUrl != null)
RedirectToPage(PageUrl, PageName, true, false)
},
error: function (xhr, ajaxOptions, thrownError) {
}
});
Then in this ajax call success i am redirecting the page with passed page url.
But still i am wondering the same code how it was working in MVC and not in asp.net core.
That's it.
I'm having some issues with updating a partial view in my index view. Basically, based on a click, I would like to have updated information.
//controller
public ActionResult Index()
{
var filteredObservations = getFilteredObservationSessions().ToList();
var observationManagementVm = new ObservationManagementVM(filteredObservations);
return View(observationManagementVm);
}
public ActionResult indexPagedSummaries(int? page, List<ObservationSessionModel> data)
{
var alreadyFilteredObservations = data;
int PageSize = 10;
int PageNumber = (page ?? 1);
return PartialView(alreadyFilteredObservations.ToPagedList(PageNumber, PageSize));
}
My main view
//index.cshtml
#model AF.Web.ViewModels.ObservationManagementVM
....
<div id="testsim">
#Html.Action("indexPagedSummaries", new { data = Model.ObservationSessions })
</div>
<input id="new-view" value="Sessions" type="button" />
<script>
$("#new-view").click(function() {
$.ajax({
type: "GET",
data: { data: "#Model.FeedBackSessions" },
url: '#Url.Action("indexPagedSummaries")',
cache: false,
async: true,
success: function (result) {
console.log(result);
$('#testsim').html(result);
$('#testsim').show();
}
});
});
</script>
....
And my partial view
//indexPagedSummaries.cshtml
#model PagedList.IPagedList<AF.Services.Observations.ObservationSessionModel>
#using (Html.BeginForm("indexPagedSummaries"))
{
<ol class="vList vList_md js-filterItems">
#foreach (var item in Model)
{
#Html.DisplayFor(modelItem => item)
}
</ol>
<div>
Page #(Model.PageCount < Model.PageNumber ? 0 : Model.PageNumber) of #Model.PageCount
#Html.PagedListPager(Model, page => Url.Action("Index",
new { page }))
</div>
}
Html.Action() returns what I want perfectly, but it doesn't seem to be able to be triggered by a button click.
So, I'm not getting any errors, but the url doesn't give any data back. When I try to run the Observation/indexPagedSummary url without passing in data, I get a System.ArgumentNullException error, so I'm assuming that something is being transferred to the view model. Any help would be so appreciated.
Have not run your code but I believe it is because you are not sending the data along with the #Url.Action
Main View:
//index.cshtml
#model AF.Web.ViewModels.ObservationManagementVM
....
<div id="testsim">
#Html.Action("indexPagedSummaries", new { data = Model.ObservationSessions })
</div>
<input id="new-view" value="Sessions" type="button" />
<script>
$("#new-view").click(function() {
$.ajax({
type: "GET",
data: { data: "#Model.FeedBackSessions" },
url: '#Url.Action("indexPagedSummaries", "[Controller Name]", new { data = Model.ObservationSessions})',
cache: false,
async: true,
success: function (result) {
console.log(result);
$('#testsim').html(result);
$('#testsim').show();
}
});
});
</script>
If that doesn't help I have had issues when I have had a content-type mismatch or a datatype mismatch. You may need to add those to you ajax request.
Change your ajax data line to this:
data: { data: JSON.stringify(#Model.FeedBackSessions) },
You may also need to add these lines to the ajax:
dataType: 'json',
contentType: 'application/json; charset=utf-8',
You can see in one of your comments above that the current URL is being formed with a description of the List Object, rather than the contents of it:
http://localhost:60985/Observation/indexPagedSummaries?data=System.Collections.Generic.List%601%5BAF.Services.Observations.ObservationSessionModel%5D&data=System.Collections.Generic.List%601%5BAF.Services.Observations.ObservationSessionModel%5D&_=1482453264080
I'm not sure if there's a better way, but you may even have to manually get the model data into Javascript before posting it.
eg:
<script>
var temp = [];
#foreach (var item in Model.FeedBackSessions){
#:temp.push(#item);
}
</script>
and then data: { data: JSON.stringify(temp) },
I'm looking for a way to do a "Update Panel" in ASP.NET MVC 3. I found this link: How to make update panel in ASP.NET MVC but didn't work.
So, i did this in my view:
<div>
<input type="text" id="userName" />
<button type="button" onclick="searchUserByName()">Search</button>
</div>
<div id="usersPanel">
#{Html.RenderPartial("_UserList", Model);}
</div>
<script type="text/javascript">
function searchUserByName() {
var userName = $("#userName").val();
$.post('#Url.Action("SearchUserByName")',
{username: userName},
function (htmlPartialView) {
$("#usersPanel").html(htmlPartialView);
}
);
}
</script>
And in my controller:
public ActionResult SearchUserByName(string userName)
{
List<User> users = // code to search users by name
return PartialView("_UserList", users);
}
But i don't know if is a good (or right) way to do that, or if there is a way to do this with asp.net mvc 3. There is a better way to do this, or with asp.net mvc 3?
Just use ajax request to get the results from your action methods. It basically does the same thing as update panels in asp.net.
So something like the following.
$.ajax({
async: false,
cache: false,
type: 'POST',
url: /controller/action,
data: { id: idParam },
beforeSend: function (XMLHttpRequest) {
if (confirmMessage !== undefined) {
return confirm(confirmMessage);
}
return true;
},
success: function (data) {
// do stuff
},
error: function () {
alert('An error occured');
}
});
I would do it like that.
You might also want to take a look at client side libraries for handling bindings etc. Looks like knockoutjs will be included in MVC4
In View:
<script type="text/javascript">
var userName = $("#userName").val();
$.ajax({
url: "/<ControolerName>/SearchUserByName",
type: "POST",
data: { userName: userName},
success: function (result) {
$('#divResults').html(result);
},
error: function (ex) {
alert("Error");
}
<script>
<div id="divResults">
</div>
In controller:
public PartialViewResult SearchUserByName(string userName)
{
List<User> users = // code to search users by name
return PartialView("_users", users);
}
I have ah HTML5 form with an action defined as follows:
#using (Html.BeginForm("SearchAction", "ResultsController"))
The form takes in two text fields:
<input type="text" name="txtSearchTerm" id="txtSearchTerm" class="frontPageInput" placeholder="Begin your search..." required />
<input type="text" name="txtGeoLocation" id="txtGeoLocation" class="frontPageInput" required />
The txtGeoLocation field is an autocomplete field that is fed from a cached object, fed through the controller and by a model repository class through the following jQuery code:
<script type="text/javascript" language="javascript">
$(function () {
$("#txtGeoLocation").autocomplete(txtGeoLocation, {
source: function (request, response) {
$.ajax({
url: "/home/FindLocations", type: "POST",
dataType: "json",
selectFirst: true,
autoFill: true,
mustMatch: true,
data: { searchText: request.term, maxResults: 10 },
success: function (data) {
response($.map(data, function (item) {
return { label: item.GeoDisplay, value: item.GeoDisplay, id: item.GeoID }
}))
}
})
},
select: function (event, ui) {
alert(ui.item ? ("You picked '" + ui.item.label + "' with an ID of " + ui.item.id)
: "Nothing selected, input was " + this.value);
document.getElementById("hidLocation").value = ui.item.id;
}
});
});
There's an alert there for debugging. When clicking on the text that drops down, this alert fires, however it does not fire if you type in the whole word and hit submit.
I would like to first, validate the text in the geo text box on the client side, to ensure that it is a value contained in the collection, of not, have the text box in red, communicate that.
Thanks.
You can use jquery remote validation using the [Remote()] attribute to validate the value is in the list. You will have to do the same check on the server side when you post back as well.
