Hide div tag on page load - c#

I have some div's in my project which has some animation on mouse-over done using java-script.
Now my problem is on page load i need to hide all the div's and display only title of the div,and on mouse-over of this title i should be able to make the div visible with all the animation done.
Below is my code:
<div id='Qhse' class="item user">
<h2>qhse</h2>
<div id='qhse' class="qhse" runat="server" >
</div>
</div>
<div id='Policies' class="item home">
<h2>policies</h2>
<div id='policies' class="policies" runat="server" >
</div>
</div>
CSS
#qhse{
padding-top: 0.3em;
padding-bottom:0.3em;
background-color: #2C6D2C;
width: 100%;
height: 100%;
text-align: center;
vertical-align:middle;
}
#policies{
padding-top: 0.3em;
padding-bottom:0.3em;
background-color: #2C6D2C;
width: 100%;
height: 100%;
text-align: center;
vertical-align:middle;
}
JS
$(function () {
$('#nav > div').hover(function () {
visibility: visible;
var field = $('#<%= hdnSelected.ClientID %>');
field.val(this.id);
var $this = $(this);
$this.find('div').stop().animate({
'width': '100%',
'height': '100%',
'top': '-25px',
'left': '-25px',
'opacity': '1.0'
}, 500, 'easeOutBack', function () {
$(this).parent().find('ul').fadeIn(700);
});
$this.find('a:first,h2').addClass('active');
},
function () {
var $this = $(this);
$this.find('ul').fadeOut(500);
$this.find('div').stop().animate({
'width': '52px',
'height': '52px',
'top': '0px',
'left': '0px',
'opacity': '0.1',
'visible': 'false'
}, 5000, 'easeOutBack');
$this.find('a:first,h2').removeClass('active');
});
});

Here is a Working Fiddle.
Added this to Document Ready.
$('#policies,#qhse').hide();
And following minor errors fixed.
visibility: visible;
'visible': 'false'
Still not able to figure out where <ul> tags are. Hide,Hover works fine.

First, a bunch of remarks:
There is no #nav in your HTML.
visibility: visible; inside a function is not a valid JavaScript.
'#<%= hdnSelected.ClientID %>' looks like you're generating your JavaScript using a server-side language. If you do, don't do it. If you don't (i.e. if it's some client-side template engine I've never seen before), make sure this line is doing what you expect it to do.
Make sure $this variable is declared.
What have you tried?
You already have your animation. What you want to do next is to show and hide elements. A simple Google search leads you to the jQuery function show(); similarly, there is a hide() function.
How can you apply those two functions to your actual code?

Here is my Hidden DIV

Here is Javascript
<script type="text/javascript">
$(".aItemLnk").click(function () {
var id = $(this).attr("id").replace(/^.(\s+)?/, "");
var contentTobeLoaded = $("#divItem" + id).html();
$('#ajax').html(contentTobeLoaded).fadeIn(100000, function () {
});
});
This is how I do mine.
Javascript
<script type="text/javascript">
$(function () {
$('.dragbox')
.each(function () {
$(this).hover(function () {
$(this).find('h2').addClass('collapse');
}, function () {
$(this).find('h2').removeClass('collapse');
})
.find('h2').hover(function () {
$(this).find('.configure').css('visibility', 'visible');
}, function () {
$(this).find('.configure').css('visibility', 'hidden');
})
.click(function () {
$(this).siblings('.dragbox-content').toggle();
})
.end()
.find('.configure').css('visibility', 'hidden');
});
</script>
HTML
<div class="dragbox" id="Widget2" runat="server">
<h2 style="font-size: 14pt">Heading Goes Here</h2>
<div class="dragbox-content">
//Information Here
</div>
</div>
So when you click on the Header (h2), it hides and when you click on it again, it is visible. You will also need some css.. here is mine.
CSS
.column{
width:49%;
margin-right:.5%;
min-height:300px;
background:#e2e2e2;
float:left;
}
.column .dragbox{
margin:5px 2px 20px;
background:#fff;
position:relative;
border:1px solid #ddd;
-moz-border-radius:5px;
-webkit-border-radius:5px;
}
.column .dragbox h2{
margin:0;
font-size:12px;
padding:5px;
background:#f0f0f0;
color:#000;
border-bottom:1px solid #eee;
font-family:Verdana;
cursor:move;
}
.dragbox-content{
background:#fff;
min-height:100px; margin:5px;
font-family:'Lucida Grande', Verdana; font-size:0.8em; line-height:1.5em;
}
.column .placeholder{
background: #f0f0f0;
border:1px dashed #ddd;
}
.dragbox h2.collapse{
background:#f0f0f0 url("../Images/collapse.png") no-repeat top right;
}
.dragbox h2 .configure{
font-size:11px; font-weight:normal;
margin-right:30px; float:right;
}
I use the 'dragbox' in a sortable jquery as well. So as you can tell, you will not need the .columns, but I showed them just incase you go that route and would like to use div's as columns. If you do, all you need to do is add
<div class="column" id="column1" runat="server">
</div>
And then place the 'dragbox' within that. You can have 2 of these 'columns'
Hope this helps.
You need a condition (if, else) to call fadeIn when the div is hidden, and fadeOut when the div is shown!
Because your code only call fadeIn so the first time, it will fadeIn and the next call it will also fadeIn, so it will stay there.
I don't know in JQuery but that's how I do it in javascript to know if the div is shown or hidden:
if(div.style.display == 'block') {
}
//call fadeOut
else {
//call fadeIn
}
Just use fadeToggle instead:
$(".aItemLnk").click(function () {
var id = $(this).attr("id").replace(/^.(\s+)?/, "");
var contentTobeLoaded = $("#divItem" + id).html();
$('#ajax').html(contentTobeLoaded).fadeToggle(100000, function () {
});
});
You can use the toggle method for your desired div inside the click event of a hyperlink.
I've made an example for you in this fiddle > jsfiddle.net/MK68L
Hope it helps

How to add an image to a dialog form with jQuery

I am working on MVC application and on one of my pages I have an image gallery. I want to do the following: when I click on any given image to open a modal dialog and display the image (the reason for that is because I don't have much space on my page).
Javascript code:
function openDialog(url)
{
$("#dialog-form").dialog("open");
document.getElementById("dialog-form").style ="display: block;"
document.getElementById("modalImg").src = url;
}
$( "#dialog-form" ).dialog({
autoOpen: false,
height: 800,
width: 850,
modal: true,
buttons: {
Cancel: function() {
$( this ).dialog( "close" );
}
},
close: function() {
allFields.val( "" ).removeClass( "ui-state-error" );
}
});
Razer View:
<div style="height: auto; width: 100%;">
#foreach (var photo in Model.Application.Screenshots.Where(p => p.Device == 1))
{
<div style="float: left; width: 250px;">
<img alt='Patka' src='#Url.Content(photo.Url)' width='250' onclick="openDialog('#Url.Content(photo.Url)')"/>
</div>
}
<div id="dialog-form" title="Screenshot Preview" style="display: none;">
<img alt='ModalPatka' id="modalImg" src=".."/>
</div>
<div style="clear: both;"></div>
</div>
However when I click on any image nothing happens. Any idea why?
Are you getting any javascript errors in your console (Firebug for Firefox or the Chrome debug console)? I am not sure of the exact problem, but I can say that you should probably clean up your javascript and use the full power of jQuery selectors, this might help solve your issue.
Here are the changes that I would recommend:
Place a class on your preview images so that we can attach a jQuery handler to the click of that element.
I am not sure if .src is a valid jQuery selector on an element. Try using the .attr() designator
Let's remove the GetElementById calls in your JavaScript and use the jQuery selectors
I think the dialog call needs to be in your .Ready jQuery function. See the examples here
Update your DOM elements before calling the .Dialog function to prevent screen flashing.
Remove the spaces in your jQuery selectors, I dont think this is causing an issue, but it would not hurt to clean those up as well (e.g. (this) instead of ( this ))..even though the jQuery UI examples have them, maybe this is just a coding style concern.
JavaScript Code
$(function(){
$(".OpenDialog").on("click", function(){
$("#dialog-form").style ="display: block;";
$("#modalImg").attr("src", $(this).attr("src"));
$("#dialog-form").dialog({
autoOpen: false,
height: 800,
width: 850,
modal: true,
buttons: {
Cancel: function() {
$(this).dialog("close");
}
},
close: function() {
allFields.val("").removeClass("ui-state-error");
}
});
});
});
Razor View
<div style="height: auto; width: 100%;">
#foreach (var photo in Model.Application.Screenshots.Where(p => p.Device == 1))
{
<div style="float: left; width: 250px;">
<img alt='Patka' src='#Url.Content(photo.Url)' width='250' class="OpenDialog"/>
</div>
}
<div id="dialog-form" title="Screenshot Preview" style="display: none;">
<img alt='ModalPatka' id="modalImg" src=".."/>
</div>
<div style="clear: both;"></div>
</div>

how to BlockUI content in new page ASP.NET C#

I can't figure out how to block content in new page with jQuery BlockUI. I have application in aSP.NET MVC. In one view I click the button and new report is generated and opened in new tab/window and I want block this page content until report is not loaded. But in my case content is blocked on first page with button and not in this new one. Can someone help me how to do this, please?
<div>
<button id="btnSubmit">Report</button>
</div>
<script type="text/javascript">
$(function () {
$('#btnSubmit').click(function () {
$.blockUI({ css: {
border: 'none',
padding: '15px',
backgroundColor: '#000',
'-webkit-border-radius': '10px',
'-moz-border-radius': '10px',
opacity: .5,
color: '#fff'
}
});
setTimeout($.unblockUI, 5000);
window.open(link, "Report");
$(document).ajaxStart($.blockUI).ajaxStop($.unblockUI);
return false;
</script>
May require some further debugging but this is the idea:
var w = window.open(link, "Report");
$(w.document).ajaxStart($.blockUI).ajaxStop($.unblockUI);

JQuery BlockUI progress indicator in every Asp.net postback

I would like to implement a jquery blockUI to popup and show a progress indicator (loading circle) during postbacks in Asp.Net. How can I implement this? I am using masterpages so I was wondering if I can implement this code in one place to keep it simple. Is this even possible? Looking forward to hear your thoughts on this.
Thanks in advance.
I was able to develop this. I have included the steps in answers. Let me know if you have questions.
I figured it out myself.
Create a new Asp.net web project.
Include the following in Site.Master markup:
<script type="text/javascript" src="../Scripts/jquery-1.4.1.min.js"></script>
<script type="text/javascript" src="../Scripts/jquery.blockUI.js"></script>
<script language="javascript" src="../Scripts/General.js" type="text/javascript"></script>
<style>
div.blockOverlay {
background-color: #666;
filter: alpha(opacity=50) !important;
-moz-opacity:.50;
opacity:.50;
z-index: 200000 !important;
}
div.blockPage {
z-index: 200001 !important;
position: fixed;
padding: 10px;
margin: -38px 0 0 -45px;
width: 70px;
height: 56px;
top: 50%;
left: 50%;
text-align: center;
cursor: wait;
background: url(ajax-loader.gif) center 30px no-repeat #fff;
border-radius: 5px;
color: #666;
box-shadow:0 0 25px rgba(0,0,0,.75);
font-weight: bold;
font-size: 15px;
border: 1px solid #ccc;
}
</style>
Add the following markup in default.aspx:
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate><asp:Button ID="Button1" runat="server" Text="Button"
onclick="Button1_Click" /></ContentTemplate>
</asp:UpdatePanel>
Add a progress indicator image (ajax-loader.gif) to project root
Add the following in General.js
// BlockUI setup
$.extend({
// Block ui during ajax post back
initializeUiBlocking: function () {
if (typeof ($.blockUI) != 'undefined') {
$.blockUI.defaults.message = 'LOADING';
$.blockUI.defaults.overlayCSS = {};
$.blockUI.defaults.css = {};
var request = Sys.WebForms.PageRequestManager.getInstance();
request.add_initializeRequest(function (sender, args) {
request.get_isInAsyncPostBack() && args.set_cancel(true);
});
request.add_beginRequest(function () { $.blockUI(); });
request.add_endRequest(function () { $.unblockUI(); });
}
}
});
$(document).ready(function () {
$.initializeUiBlocking();
});
Have a look at this
http://www.malsup.com/jquery/block/#overview
This works for ajax calls.
And you need to place the following line
$(document).ajaxStart($.blockUI).ajaxStop($.unblockUI);
in a place available to all pages.
Introduction:
To Block the Page when Data is Submitting, we have various options, Either we can use Ajax based UpdateProgress or some jQuery Stuff. But sometime Ajax UpdateProgress not very useful because of complexity. So, the better approch appoach is to use jQuery UI Block Plug-In.
Implementation:
Download jQuery UI Block Plugin from : http://www.malsup.com/jquery/block/
<script type="text/javascript" src="js/jquery.1.4.2.js"></script>
<script type="text/javascript" src="js/jquery.blockUI.js"></script>
$("#<%= btnSubmit.ClientID%>").click(function() {
$.blockUI({
message: "<h3>Processing, Please Wait...</h3>" ,
css: {
border: 'none',
padding: '15px',
backgroundColor: '#000',
'-webkit-border-radius': '10px',
'-moz-border-radius': '10px',
opacity: .5,
color: '#fff'
} });
});
The above code is simple code without any AJAX or other complex script.
I found this Article on Website and tested, its work fine

JQuery bring expanded image to front

Hi I am working with a JQuery expand image function and I needed the expanded image to be on the front overlapping others but somehow I couldn't find a way to do it, I have tried to place the z-index on multiple locations but no help, please kindly advice, thanks!:
<style type="text/css">
.growImage {position:inherit ;width:80%;left:15px;top:15px; z-index:1;}
.growDiv { left: 60px; top: 60px;width:130px;height:130px;position:inherit ; z-index:-1; }
</style>
<script type="text/javascript">
$(document).ready(function () {
$('.growImage').mouseover(function () {
$(this).stop().animate({ "width": "100%", "right": "10px", "top": "20px" }, 200, 'swing');
}).mouseout(function () {
$(this).stop().animate({ "width": "80%", "right": "15px", "top": "15px" }, 400, 'swing');
}); ;
});
</script>
My DataList:
<div style="width: 414px; height: 114px;">
<div class="MostPopularHead">
<asp:Label ID="LabelTitle" runat="server" Text=" Customers who bought this also bought:"></asp:Label></div>
<div id="Div1"
style="padding: 10px; background-color:#EDECB3; height: 322px; width: 372px;"
runat="server">
<asp:DataList ID="DataItemsList" runat="server" RepeatColumns ="3" Width="16px"
Height="108px" >
<HeaderTemplate></HeaderTemplate>
<ItemTemplate>
<a class='MostPopularItemText' href='ProductDetails.aspx?productID=<%# Eval("ProductId") %>&&CategoryId=<%# Eval("CategoryId") %>'
style="padding-right: 3px; padding-left: 3px">
<div class="growDiv">
<img class="growImage" alt="image" src='Styles/CatalogImages/Images/Thumbs/<%# Eval("ProductImage") %>'/>
</div></a>
</ItemTemplate>
<FooterTemplate></FooterTemplate>
</asp:DataList>
</div>
</div>
can you make with this
.css('z-index', parseInt( new Date().getTime()/1000 ));
Two things:
z-index will always be 'auto' unless using position of relative, absolute or fixed. Therefore, position:inherit will not work.
Update your css:
.growImage { position:relative; width:80%;left:15px;}
.growDiv {
position:relative; left: 60px; top: 60px;width:130px;height:130px;
}
Now, I made a JSFiddle to show that I got it working but I had to modify the HTML structure a bit: http://jsfiddle.net/Dpzur/4/
You will need to view the source created by your .aspx page to see how many divs, starting from any div with class: 'growDiv', that you must traverse upwards through until you are at the div element that represents its parent "ItemTemplate".. so you will need to modify my jQuery:
$(this).closest('.growDiv').first().css('z-index', 2);
to:
$(this).closest('.growDiv').first().closest('div').closest('div').css('z-index', 2);
, where you add in a .closest('div) for each div element that you need to traverse upwards through the DOM. Make sense?
