我正在动态创建一个表并将其解析为一个表。显示表格后，我希望用户能够对所有行进行实时搜索。我在让它正常工作方面遇到问题。

包含的源代码 - 跳到下一个代码部分，查看与表行的实时搜索特别相关的 js。

                var Pairing = Parse.Object.extend("golfTourney");

                var Pairings = Parse.Collection.extend({
                        model: Pairing

                        closeTemplate: _.template($("#closeDay").html()),

                        initialize: function() {
                                _.bindAll(this, 'render');
                                var self = this;

                                this.collection = new Pairings;

                                console.log(this.collection);

                                this.collection.sortBy(function(m){
                                        return m.get("GroupID");

                                this.collection.forEach(function(m){
                                        var pairing = new PairingView({model: m});
                                        html += pairing.render();
                                });

                                html += this.closeTemplate();
                                this.$el.append(html);
                        }
                });

                var appview = new AppView();
        });

这是有问题的js....

        $('#pairingsTable').load(function(){

                var $rows = $('#pairingsTable tr');
                $('#search').keyup(function() {
                        var val = $.trim($(this).val()).replace(/ +/g, ' ').toLowerCase();

                        $rows.show().filter(function() {
                                var text = $(this).text().replace(/\s+/g, ' ').toLowerCase();
                                return !~text.indexOf(val);
                        }).hide();
                });
        });
        </script>

</head>
<body>

        <div>

        </div>

</body>
</html>

我在这里想念什么？由于我的内容是动态生成的，我不能使用这种方法吗？

谢谢

问题确实是 DOM 是在页面加载后创建的。因此，一旦呈现视图，您就需要以某种方式绑定到keyup事件。#search有几种方法可以做到这一点，但这里有一种方法：

$(function(){
    Parse.$ = jQuery;
    // Connect to Parse

    Parse.initialize("soyC2zYsel97QtRsNhhNUxLoBgKe6kxnX0WxUBYT", "mZL82WFBjR2UUwJrwIu5WYLoRr0FzjPlHiTrD8zj");

    var Pairing = Parse.Object.extend("golfTourney");

    var Pairings = Parse.Collection.extend({
        model: Pairing
    });

    var PairingView = Parse.View.extend({
        template:  _.template($("#pairing").html()),

        initialize: function(){
            _.bindAll(this, 'render');
        },

        render: function(){
            return this.template(this.model);
        }
    });

    var AppView = Parse.View.extend({
        el: $("div"),
        openTemplate: _.template($("#openDay").html()),
        closeTemplate: _.template($("#closeDay").html()),

        initialize: function() {
            _.bindAll(this, 'render');
            var self = this;

            this.collection = new Pairings;
            this.collection.query = new Parse.Query(Pairing);
            this.collection.query.ascending("GroupID");
            this.collection.fetch();

            this.collection.bind('reset', function(){
                    self.render();
            });
        },

        render: function(collection) {
            var self = this, html = this.openTemplate();

            this.collection.sortBy(function(m){
                return m.get("GroupID");
            })

            this.collection.forEach(function(m){
                var pairing = new PairingView({model: m});
                html += pairing.render();
            });

            html += this.closeTemplate();
            this.$el.append(html);
            $(document).trigger('list-rendered');        
        }
    });

    var appview = new AppView();
});

$(document).on('list-rendered', function() {
    var $rows = $('#pairingsTable tr');
    $('#search').on('keyup', function() {
        var val = $.trim($(this).val()).replace(/ +/g, ' ').toLowerCase();

        $rows.show().filter(function() {
            var text = $(this).text().replace(/\s+/g, ' ').toLowerCase();
            return !~text.indexOf(val);
        }).hide();
    });
});​

现在我们正在触发一个自定义事件，该事件list-rendered在 render 方法的末尾使用$(document).trigger('list-rendered');. 该事件被监听并与底部的代码绑定。
