Yii afterAjaxUpdate happening 13 times?

Question

in my CGridView I have this simple function:

'afterAjaxUpdate' =>
'function(id, data) {
    var checks2 = $("#checks").val().split(",").sort();
    $("#rule-competitors-grid input:checkbox").each(function() {
        console.log($.inArray($(this).attr("name").substr(11,$(this).attr("name").length - 12), checks2));
        if ($.inArray($(this).attr("name").substr(11,$(this).attr("name").length - 12), checks2) !== -1)
            $(this).attr("checked", "checked");
    });
}',

On a list that shows 2 items at a time (for debugging).

See the console.log()s over there? They happen 13 times each call. How can I fix this?

Answer 1

The solution was dumb and unrelated, but I'm sure someone in this world might encounter the same.

My problem was that the JavaScript was loaded through AJAX in the loaded page in a dialog/tab and not in the main page. What happens is that the "click" trigger was re-assigned, and added to the elements every time I reloaded the tab/dialog. After reloading it 13 times to check on small changes (since it's an AJAX dialog I was able to avoid having to update the whole page), it was loaded inside.

To avoid this, either unbind the events as soon as the dialog/tab is reloaded, or use .on() to lively load it on the main page and not the tab/dialog so the code isn't re-added to the event every time you load it.
