How to set a value of the textarea without id by javascript?

rated 0 times [ 144] [ 6] / answers: 1 / hits: 19604 / 13 Years ago, sun, december 4, 2011, 12:00:00

Typically we run javascript code to set any value:

document.getElementById('id_name').value = ...;

But I have a page like this:

<div id=id_name>

    <div class=class_name>

        <textarea></textarea>

    </div>

</div>

How to set a value of the textarea by javascript?

Thanks a lot for help!

You could do this, if your HTML is really that simple:

var textarea = document.getElementById('id_name').getElementsByTagName('textarea')[0];

textarea.value = hello world;

There's also a getElementsByClassName() in newer browsers that could be used to find the class_name <div> element, from which you'd do the getElementsByTagName() call.
