javascript - Object [object HTMLAnchorElement] has no method 'attr' - Stack Overflow

programmeradmin4浏览0评论

I'm examining a DOM element using console.log. The DOM element is an anchor:

 <a href="#" class="videoimage" data-id="ks3H_s3e-Wc"></a>

When I try to access its id and output it using either of the following lines:

console.log($this.attr(data-id));

or

console.log($this.data('id'));

I get an error:

Object [object HTMLAnchorElement] has no method 'attr'

('data' in the second case)

Does an anchor element not have the attr or data methods, or is my mistake something else?

  • Thanks but that's what i meant, it was a typo, that wasnt it – Solorzano Jose Commented Apr 18, 2013 at 2:53
  • 2 That error message happens because you are trying to use a jquery method 'attr' on an html object. So the answer to why you get the message is that 'this' is not a jquery object. – Coin_op Commented Apr 18, 2013 at 3:04

Reset to default 12

That looks like its because your this reference is not a jquery object. Try these instead:

$(this).data('id')
$(this).attr('data-id')

It is telling you exactly what the problem is. .data and .attr are jQuery functions. If your want to get an attribute value using a javascript object do the following, after giving an id to your element:

console.log(document.getElementById("a").getAttribute("data-id"));

jsFiddle: http://jsfiddle/hescano/pFdEj/

Something else is wrong in your page, then. The following does work:

$(this).data("id")

http://jsfiddle/RQw8E/

How are you using $(this)?

Works for me:

HTML

<a href="#" class="videoimage" data-id="ks3H_s3e-Wc">Click</a>

JavaScript

$(".videoimage").click(function() {
    var dataID = $(this).data("id");
    var dataIDAttr = $(this).attr("data-id");
    console.log(dataID);
    console.log(dataIDAttr);
});

JSFiddle

Are you sure you attached some sort of event to the function that calls these statements?

You could also use vanilla JS

var anchorArr = document.getElementsByTagName("a");
for (var i = 0; i < anchorArr.length; i++) {
    if(anchorArr[i].getAttribute("class")==="videoimage") {
        //^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 
        //quick and dirty, there are better ways to do this
        console.log(anchorArr[i].getAttribute("data-id"));
    }
}
