The attr( properties) method set a key/value object as properties to all matched elements.
Here is the simple syntax to use this method:
selector.attr({property1:value1, property2:value2}) |
Here is the description of all the parameters used by this method:
property: This is the CSS property of the matched element.
value: This is the value of the property to be set.
Following example would change the properties of an image tag:
<html> <head> <title>The Selecter Example</title> <script type="text/javascript" src="/jquery/jquery-1.3.2.min.js"> </script> <script type="text/javascript" language="javascript"> $(document).ready(function() { $("img").attr({ src: "/images/jquery.jpg", title: "jQuery", alt: "jQuery Logo" }); }); </script> </head> <body> <div class="divcl" id="divid"> <p>Following is the logo of jQuery</p> <img src="Wrong SRC" title="None" alt="None" /> </div> </body> </html> |
This would generate following result:
<html> <head> <title>The Selecter Example</title> <script type="text/javascript" src="/jquery/jquery-1.3.2.min.js"> </script> <script type="text/javascript" language="javascript"> $(document).ready(function() { $("img").attr({ src: "/images/jquery.jpg", title: "jQuery", alt: "jQuery Logo" }); }); </script> </head> <body> <div class="divcl" id="divid"> <p>Following is the logo of jQuery</p> <img src="/images/jquery.jpg" title="jQuery" alt="jQuery Logo" /> </div> </body> </html> |
