In
this article I am going to explain how to change the background color of div
using jquery.
In
the previous article I have explained how to open image in popup on thumbnailclick using Jquery and how to search the record and highlight in Gridview usingAsp.net.
Description:
I
want to change the background of a particular area (div). To fulfill this requirement I am using evol
colorpicker Jquery.
Implementation:
I
have added textbox and button control to webform.
Add
the reference of script and CSS before closing head tag.
<link id="jquiCSS"
rel="stylesheet"
href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.11.1/themes/ui-lightness/jquery-ui.css"
type="text/css"
media="all">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"
type="text/javascript"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.11.1/jquery-ui.min.js"
type="text/javascript"></script>
<script src="js/evol.colorpicker.js" type="text/javascript"></script>
<link href="css/evol.colorpicker.css" rel="stylesheet"
type="text/css"
/>
<style>
#section
{
margin-top:20px;
width:300px;
height:300px;
}
</style>
<script>
$(document).ready(function () {
$('#txtcolor').colorpicker({
initialHistory: ['#ff0000', '#000000',
'red']
})
.on('change.color', function (evt, color) {
$('#section').css('background-color', color);
})
.on('mouseover.color', function
(evt, color) {
if (color)
{
$('#section').css('background-color', color);
}
});
});
</script>
Complete
HTML markup of webform:
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<link id="jquiCSS"
rel="stylesheet"
href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.11.1/themes/ui-lightness/jquery-ui.css"
type="text/css"
media="all">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"
type="text/javascript"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.11.1/jquery-ui.min.js"
type="text/javascript"></script>
<script src="js/evol.colorpicker.js" type="text/javascript"></script>
<link href="css/evol.colorpicker.css" rel="stylesheet"
type="text/css"
/>
<style>
#section
{
margin-top:20px;
width:300px;
height:300px;
}
</style>
</head>
<body>
<form id="form1" runat="server">
<fieldset style="width:310px">
<legend>Change

<asp:TextBox ID="txtcolor" runat="server"></asp:TextBox><asp:Button ID="Button1"
runat="server"
Text="Change

<div id="section" runat="server">
</div>
</fieldset>
</form>
<script>
$(document).ready(function () {
$('#txtcolor').colorpicker({
initialHistory: ['#ff0000', '#000000',
'red']
})
.on('change.color', function
(evt, color) {
$('#section').css('background-color', color);
})
.on('mouseover.color', function
(evt, color) {
if (color)
{
$('#section').css('background-color', color);
}
});
});
</script>
</body>
</html>
