Backbone.js-使用jquery mobile渲染集合而无需样式

Question

I'm creating a mobile view that uses backkbone.js and jquery mobile.

I have a collection that I render to the page, styled up to use jquery mobile's listview . The collection loads and is rendered on the page with the correct html, but renders as an un-styled list, not how it should render in jquery mobile. If I then inspect the list, copy it as html, and paste it into my html page as static html, that html displays correctly!

What am I doing wrong? This is my first foray into both backbone.js and jquery mobile so it could be something simple.

Code:

My templates:

<script id="change-template" type="text/template">
<a href="#">{{ Description }}</a>
<p>{{ ChannelLabel }}</p>
</script>

<script id="changes-template" type="text/template">
<ul id="changes-list" data-role="listview" data-inset="false" data-filter="true"></ul>
</script>

My views:

window.ChangeView = Backbone.View.extend({

    tagName: 'li',

    initialize: function() {
        _.bindAll(this, 'render');
        this.template = _.template($('#change-template').html());
    },

    render: function() {
        this.$el.html(this.template(this.model.toJSON()));
        return this;
    }
})

window.ChangesView = Backbone.View.extend({

    tagName : "div",

    initialize: function () {
        _.bindAll(this, 'render');
        this.template = _.template($('#changes-template').html());
        this.collection.bind("reset", this.render);
    },

    render: function () {

        var collection = this.collection;

        // Render the template
        $(this.el).html(this.template({}));

        // Then get a handle to the element inside the template.
        var $changes = this.$('#changes-list');

        this.collection.each(function(change) {
            var view = new ChangeView({model: change, collection: collection});
            $changes.append(view.render().el);
        })

        return this;
    }
});

Example HTML output:

<div id="changes" data-role="content" class="ui-content" role="main">
<ul id="changes-list" data-role="listview" data-inset="false" data-filter="true"><li>
  <a href="#">Link Up</a>
  <p>GF1A-R2P24 - 23</p>
  </li><li>
  <a href="#">Link Down</a>
  <p>GF1A-R2P24 - 23</p>
  </li></ul>
</div>

This is how I load the page:

$(document).bind('pageinit',function () {

    window.changes = new Changes();
    var view = new ChangesView({ collection: changes, el:"#changes" });
    changes.fetch();
});

Answer 1

Ok, so by looking around, I found that adding this solved the issue:

$(this.el).trigger( "pagecreate" );

But this feels wrong - why should I need to trigger that event myself?

Answer 2

If all the DOM-changes were done before the jQuery Mobile started styling the page, it would work just fine. However, Backbone.js' events cause parts of the page to re-render asynchronously, leaving parts of the page unstyled.

Calling .trigger("pagecreate") or "create" triggers jQuery Mobile to restyle the page/elements.

(Each time jQuery Mobile displays a page it reads the data- attributes and applies the appropriate styling.)

This is necessary because jQuery Mobile and Backbone.js are separate frameworks.
