javascript ElementById clarification

My input tag looks like this:

<input type="text" name="kkk" value="dis" disabled="disabled"></input>

This is my JavaScript function

function get(){
    alert(document.getElementById("kkk").value);
}

Though I don't have id for the above tag value gets printed when using getElementById. Can any one explain me the behavior?

My guess is you're using Internet Explorer, which uses name as well as id (in several versions); more here. Microsoft even documents this, but it's out-of-spec behavior which is fixed in IE8 and above (in standards mode).

You are experiencing error recovery / backwards compatibility features that appear in some browsers (related to a time when giving an element a name or an id created a global variable of the same name), particularly when a standards-mode triggering Doctype is missing. You should not depend on this.
