Get element tag name and length with Jquery each

Question

I'm trying to get info about all element tags and there frequency in the page, this is how I find the tag, very simple:

$('body *').each(function(){
var string = this.tagName;

But the length doesnt catch up:

var count =  $(this).length;

It gives me 1 while there are two divs, example: JsFiddle

I can solve this problem by removing the each function but I need it for the tagname. I have to use body * for my project so I can't refer directly to the divs.

Answer 1

You're not iterating each kind of tag with body *, you're iterating over each tag individually. The length will always be one, because this is always a single DOM element.

You should enumerate the tags you want to count, and iterate over them:

var tags = ['div', 'li', 'a'];

tags.forEach(function (tag) {
  console.log(tag, "appears", $('body ' + tag).length, 'times');
});

Output from running in the JS console on this page:

div appears 141 times
li appears 66 times
a appears 179 times 

Answer 2

Try it:

var count =  $(string, 'body').length;
