Callback not executing from jQuery post

callback, jquery, post

Solution

Your code is fine other than that it doesn't hook the error handler (one of the reasons I don't like `$.post`). I think the POST operation must be resulting in an error. Try converting it to this:

$.ajax({
  type:    "POST",
  url:     "/"+contentId+"/postComment",
  data:    {"postComment":""},
  success: function(data) {
        alert('call back');
  },
  // vvv---- This is the new bit
  error:   function(jqXHR, textStatus, errorThrown) {
        alert("Error, status = " + textStatus + ", " +
              "error thrown: " + errorThrown
        );
  }
});

...so you can see what the error is.

Problem

I'm having problems executing the call back function. ``` $.post("/" + contentId + "/postComment", { "postComment": "" }, function(data) { alert('call back'); }); ``` This post does take place. The alert is not called, however. This post results in some `xml` returned. I can't tell exactly how it looks because I'm using Spring mappings of `application/xml` together with `@RequestBody` and I just don't know what Spring does to what I'm returning. I'm saying this just in case the contents of server response can affect the call back somehow. The question is: what do I need to do to see that alert in my code example?
