Change the class name of div tag

[shridharmaster]

Hi friends, I have created the no.of div tags in my website applications.
Now i want to change the class name of the tags. How should I?
Below is some code which i want to change:-

<test.aspx>

<tr>
                <td style="width:100%;">
                    <div class="roundedcornr_box_203203">
                        <div class="roundedcornr_top_203203"><div></div></div>
                         <div class="roundedcornr_content_203203">
                        <iframe id="Graphframe" name="Graphframe" scrolling="no" marginwidth="0" marginheight="0" frameborder="0" style="width:100%;"  src="pgeGraph.aspx"></iframe>
                 </div>
                        <div class="roundedcornr_bottom_203203"><div></div></div>
                    </div>
                </td>
            </tr>

Now i want to change the class name at runtime using javascript
e.g. roundedcornr_box_203203 will be replaced by roundedcornr_box_408625 etc...
I need this very soon.
Thanks in advance

You can use the script at
http://code.google.com/p/getelementsbyclassname/
to get the list of elements of a given class name and than iterate through the list and change the className property of each element in javascript

[GreenDay2001]

Get all elements with class name you want either by using getElementBYClass Name or using getAttribute(); and then change its name using setAttribute();. Can guarantee if this will really work well, so try it out.

For changing names in source, replace using Regular Expressions using your text editor.
