Selecting element from DOM with JavaScript and XPath

Question

I\'m trying to figure out how to select the textarea in the code below using xpath and JavaScript (which is the only option here).

Answer 1

@Mark Robinson comment is right, your Xpath expression is wrong, you could use one of those :

//body/div/div/form/p/textarea (Mark's example)
//body//form/p/textarea (any form in body)

Plus, the evaluate function will return a XPathResult object, not the textarea, so you can't do directly element.value

Here is your example fixed:

--

var element = document.evaluate( '//body/div/div/form/p/textarea' ,document, null, XPathResult.ANY_TYPE, null );

var textarea = element.iterateNext ();
textarea.value = "Hello textarea";
