How To Iterate A Result Of Jquery Selector

I want to iterate a result of query selector. Html code

nav1

Solution 1:

Use $.each

$("#navigation > a").each(function() {

     console.log(this.href)
});

---

$('#navigation > a')[0]
      ^              ^---- Selects the 1st dom object from the jQuery object
      |                    that is nothing but the index of the element among 
      |                    the list of elements
      |-------  Gives you children of nav(3 anchor tags in this case)  which is a
                jQuery object that contains the list of matched elements

Solution 2:

If you want to iterate all <a> tags, you can use each function

$('#navigation >a').each(function() { 
    alert(this.href);
});

and if you only want to get the first <a> tag then use .eq()

alert($('#navigation >a').eq(0).attr('href');

Solution 3:

Use first() like this:

var element = $("#navigation>a").first();
console.log(element);

Reference

Solution 4:

In jQuery, when you use index like [0], it means you are access the DOM element. That is why

$("#navigation >a")[0]

returns <a> tag.

In order to iterate a jQuery selector result, use each

$("#navigation >a").each(function(index, elem){
});

Solution 5:

You can use jQuery built-in each() for this iteration like this:

$("#navigation>a").each(function(index){
    console.log("I am " + index + "th element.");
    //and you can access this element by $(this)
});
