如果我不在ajax调用的成功函数中包含选择器，则无法选择ajax加载的内容

Question

如果jquery select在ajax成功函数之外，我无法选择通过ajax调用插入的任何元素。如果我把所有东西都取得成功，那就行得很好。

任何有经验的人都可以帮助我了解正在发生的事情以及如何处理这个问题？我正在寻找2天已经找不到任何东西：S

这有效：

//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,

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

听起来问题是你正在尝试将事件处理程序绑定到尚不存在的元素。尝试在执行代码时使用的父元素上使用on，delegate或live（取决于您使用的jQuery版本）。

类似的东西：

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