There are a lot of ways to do it. For example:
$(".btnRemove").click(function() {
var $this = $(this);
if ($this.data("executing")) return;
$this
.data("executing", true)
.attr("src", "/url/to/ajax-loader.gif");
$.get("/url/to/django/view/to/remove/item/" + this.id, function(returnedData) {
// ... do your stuff ...
$this.removeData("executing");
});
});
or
$(".btnRemove").click(handler);
function handler() {
var $this = $(this)
.off("click", handler)
.attr("src", "/url/to/ajax-loader.gif");
$.get("/url/to/django/view/to/remove/item/" + this.id, function(returnedData) {
// ... do your stuff ...
$this.click(handler);
});
}
We can also use event delegation for clearer code and better performance:
$(document).on("click", ".btnRemove:not(.unclickable)", function() {
var $this = $(this)
.addClass("unclickable")
.attr("src", "/url/to/ajax-loader.gif");
$.get("/url/to/django/view/to/remove/item/" + this.id, function(returnedData) {
// ... do your stuff ...
$this.removeClass("unclickable");
});
});
If we don't need to re-enable the handler after it has been executed, then we can use the .one()
method. It binds handlers that are to be executed only once. See jQuery docs: http://api.jquery.com/one
