JavaScript CSS选择器，选择ID

Question

I'm trying to get the element using document.querySelectorAll() method.

var elementList = Firebug.browser.document.querySelectorAll("DIV[id='hplogo']");

when I use this with Google web site, this function returns an array with 44 elements. Please give me a solution...

Answer 1

document.querySelectorAll will return all elements on the page that match your query, hence why you're seeing 44 different elements.

Use document.getElementById('hplogo') instead of querySelectorAll to get the one element with the ID that you're looking for.

Answer 2

Firebug.browser.document.querySelectorAll("DIV#hplogo]");

please try this.

btw what is hplogo? is it a variable or is it a selector?
