jQuery – How can I temporarily disable the onclick event listener after the event has been fired?

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
