如何发送此锚的ID作为函数参数？

Question

Edit: Sorry guys, I got the issue, Misspelled class name :(
Hey, I got a quick question for your guys here. I have some anchor tags each of them points to a url of a certain user. The link id is the username. All the links share a css class (.userset). When a user clicks the link I need to issue an Ajax request -using jQuery.ajax method- to a server resource passing in the id of the link. Here's how my code looks like:
JS

 $(".columnist_set .img").click(function() {

        alert("this.id =" + this.id);
        var x = track(this.id);
});

This doesn't seem to work for me! this.id is always undefined.
Yeah, I'm suer I'm missing something, so what am I missing dear SO Gus?

Answer 1

Edit (I was on the wrong track because of some probably incorrect assumptions)

Try the following:

$(".columnist_set .img").click(function() {
        var id = $(this).attr("id");
        alert("id =" + id);
        var x = track(id);
});

Answer 2

你可以试试

$(this).attr("id");

Answer 3

You can try this:

$(".userset").click(function() {
   var x = track($(this).attr("id"));
});

Answer 4

Reading your request i can feel some confusion.

Your request says:

I have some anchor tags each of them points to a url of a certain user.

With this sentence you mean you have many <a> in your code, with the href attribute pointing to some user-driven path.

The link id is the username. All the links share a css class (.userset).

More info, why not. Your tag now should look in my mind like <a class=".userset" id="myUserName" href="./some/url">content</a>

When a user clicks the link I need to issue an Ajax request -using jQuery.ajax method- to a server resource passing in the id of the link

Let's add the click event:

   //all the anchor tags with "userset" class
   $('a.userset').click(
      function(){
          //doing the ajax call
          $.ajax({
              type: "POST",
              url: $(this).attr("href"),      //picking the href url from the <a> tag
              data: "id=" + $(this).attr("id"),    //sanitize if it's a free-inputed-string
              success:
                function(result) {
                    alert("I AM THE MAN! Data returned: " + result);
                }
              }
          );
      }
   );

With that being said, i can't really understand what your javascript code (with references to .img class ?) is referring to.

Hope my answer helped a bit though.

Answer 5

The problem is that, I misspelled the class name so the returned wrapped set of my selector is undefined. Thanks for your help all though.
