如果我沒有在ajax調用的成功函數中包含選擇器，則無法選擇ajax加載的內容

Question

如果jquery select在ajax成功函數之外，則無法選擇通過ajax調用插入的任何元素。 如果我把一切都成功了，那就很好了。

有經驗的人可以幫助我了解正在發生的事情以及如何處理此問題？ 我搜索2天已經找不到任何東西：S

這有效：

//Show levels using ajax
//define variables
var levels = 2; //level count can be rewritten to come from DB and not be hardcoded like now
var completed_calls = 0; //count tasks start from 0
var views = new Array();
//All level display ajax function
function create_views(level) {
        $.ajax({
            url: "actions.php",
            type: "GET",
            data: "show_level=" + level,
            cache: false,
            success: function (data){
                views[level] = '<li data-level="' + level + '">' + data + '</li>';

                //Count completed tasks
                completed_calls++;

                //if last level is being called append and activate slider
                if (levels == completed_calls) {
                    //append views to container
                    $(".slides_container").append(views.join(' '));
                    //activate slider
                    var unislider = $(".slides_container").dpUniSlider({
                        //loop: false,
                        draggable: false

                            unislider.goToSlide(2);
                            $("#loginform, #register h2").delay(480).fadeTo(0, 1);
                                $("#logwindow").removeClass("active").addClass("notactive");
                                $("#regwindow").removeClass("notactive").addClass("active");

如果jquery select在ajax成功函數之外，則無法選擇通過ajax調用插入的任何元素。 如果我把一切都成功了，那就很好了。

聽起來問題是您正在嘗試將事件處理程序綁定到尚不存在的元素。 嘗試on執行代碼時出現的父元素上使用on ， delegate或live （取決於您使用的jQuery版本）。

就像是：

$(".slides_container").on('click', 'li[data-level]', function () {...});
