點擊動作不會綁定

Question

下面的代碼僅在我注釋掉點擊代碼時才起作用-即，如果我不注釋掉click事件處理程序，則懸停功能甚至不起作用，所以我知道這是罪魁禍首。 有什么問題的想法嗎？

非常感謝！

 $(document).ready(function() {

    /* helper function to main database querying function
       below. Figures out the number of activities needed
       for completeness. Takes the box's class name as an
       argument
    */
    var complete = function(arg) {
        switch(arg) {
            case "three":
                return 3;
            case "four":
                return 4;
            case "seven":
                return 7;
        }
    };


    // determine if we change color of box
    var changeColor = function(arg) {
        if (arg.hasClass("zero")) {
            arg.removeClass("zero").addClass("between");
        }
            else if (arg.hasClass("between")) {
                if (numComplete == toComplete) {

綁定單擊事件中的每個循環中都有語法錯誤。 錯誤在這里： $.each(result, function (key, val)) {應該是，

$.getJSON("time.php", function(result) {
        $.each(result, function(key, val) {
            recentlyCompleted = val;
        });
    });

修復了由於“每個”語句附近括號放置錯誤而導致的錯誤。 謝謝！
