  • 0

I’m creating a table dynamically and parsing it into a table. Once the table is displayed, I’d like users to be able to do a live search through all the rows. I’m having issues with getting this to work properly.

Source included – skip to next code section to see js specifically related to the live search of table rows.

                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){

                                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();
        });

This is the js in question….

        $('#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>

What am I missing here? Can I not use this method since my content is being generated dynamically?

thanks

    The problem is indeed that the DOM is created after the page is loaded. So you need to somehow bind to the keyup event on #search once the view is rendered. There are a couple ways to do this but here is one way:

    $(function(){
    Parse.$ = 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();
    });
});​

    Now we are triggering a custom event named list-rendered at the end of the render method with $(document).trigger('list-rendered');. That event is listened for and bound to with the code at the bottom.
