INTRODUCTION
Attributes define the actual element's style, id etc for any element. For example, element <div> will have attributes like.
- id
- style
- align
- lang
- title
Now we will see how can we get the existing value of these attribute and also how to reset the values by the following example.
Example Program
attributes.jsp
<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Attributes Setter/Getter</title>
</head>
<script type="text/javascript" src="lib/jquery-1.8.0.min.js"></script>
<script type="text/javascript" src="js/attributes.js"></script>
<body>
<div id="myDiv" style="background: red; width: 200px" align="left" lang="en" title="MySampleDiv">MyDivContent</div>
<input type="button" id="btn" value="Attributes" />
<br>
<br>
<table border="1">
<tr>
<td id="td1"></td>
<td id="td2"></td>
<td id="td3"></td>
<td id="td4"></td>
</tr>
</table>
</body>
</html>
|
attributes.js
$(document).ready(function() {
$("#btn").click(function() {
// Get the existing attribute values
$("#td1").text($("#myDiv").attr("style"));
$("#td2").text($("#myDiv").attr("align"));
$("#td3").text($("#myDiv").attr("title"));
$("#td4").text($("#myDiv").attr("lang"));
// Reset the existing attribute values
$("#td1").text($("#myDiv").attr('style', 'background:blue'));
$("#td2").text($("#myDiv").attr("align", 'right'));
$("#td2").text($("#myDiv").attr("title", "NewDivValue"));
$("#td2").text($("#myDiv").attr("lang", "jp"));
});
});
