Iterating through all the tags on a page

Question

I want to go through all the elements on a page using Javascript and see if they have a property set. Is there an easy way to do this, or do I have to use a recursive solution?

Answer 1

To find a property in one or more of all divs on a page:

var divs = document.getElementsByTagName("div"), i=divs.length;
while (i--) {
   if (divs[i].getAttribute([yourProperty]) === 'yourValue'){
      //do something
   } 
}

Answer 2

You might also be able to use a selector engine such as Sizzle.

You can use:

var divs = document.getElementsByTagName("div");
for(var i = 0; i < divs.length; i++){
   //do something to each div like
   divs[i].innerHTML = "something new...";
}
