jQuery ajax request awkward issue - php

Question

So I have this ajax request. When the user clicks an edit link, I fetch the ID of the entry and refresh the page with the data of that entry loaded into a form.
Here's my problem: This only works with the alert showing before the ajax call. When I leave out the alert, I get an ajax error (though the id is being posted) and the PHP page just reloads. Moreover, it only works when I put the newDoc stuff as a success callback. The exact same lines as a complete callback and the page reloads. Moreover, this occurs in Firefox only.
jQuery('a.edit').on('mousedown', function (e) {
e.preventDefault();
var id = jQuery(this).attr('data-title');
alert('test');
jQuery.ajax({
url: document.location,
data: {
id: id
},
success: function (data) {
var newDoc = document.open("text/html", "replace");
newDoc.write(data);
newDoc.close();
},
error: function () {
alert('error');
}
});
});
What can I do?
EDIT: This must be a timing issue. I just noticed that when I click and hold the edit link for a second or so, everything works fine. When I do a short click, it doesn't. So I tried wrapping the ajax in setTimeout(), but that didn't help. Any other ideas?

Answer 1

Try to use location.href in place of document.location,
jQuery.ajax({
url: location.href,
data: {
id: id
},
success: function (data) {
var newDoc = document.open("text/html", "replace");
newDoc.write(data);
newDoc.close();
},
error: function () {
alert('error');
}
});
location is a structured object, with properties corresponding to the parts of the URL. location.href is the whole URL in a single string.

Got it!
The problem is the way Firefox handles the mousedown event. It seems to abort the ajax call as soon as you relase the mouse button. I changed the event to click and everything is fine now.
jQuery('a.edit').on('click', function () {
var id = jQuery(this).attr('data-title');
jQuery.ajax({
url: document.location,
data: {
id: id
},
success: function (data) {
var newDoc = document.open("text/html", "replace");
newDoc.write(data);
newDoc.close();
}
});
});
