javascript - Why alert AnchorElement (<a>) alerts the href attribute?

Question

<a href="url">A link</a>

$.each($('a'), function(index,value){
    alert (value)
});

It will alert : url. Why this happens?

Answer 1

It's because the toString() of the anchor gives the URL.

Live DEMO

alert calls toString() implicity on objects. so when you alert an array like:

[1,2,3,4,5,6]

Alerting it will give you:

"1,2,3,4,5,6"

Because the toString() of array is the elements separated by a comma.

If you encounter this problem while debugging, you should use console.log() instead of alert()
