提交表单事件未触发



我开发了第一个主干RESTfull应用程序。我有以下观点:

var app = app || {};
app.AssessorsCollectionView = Backbone.View.extend({
    el: '#assessors',
    tagName: 'table',
    events:{
        "submit form": "searchAssessors"
    },
    initialize: function() {
        this.collection = new app.AssessorsCollection();
        this.collection.fetch({reset: true, data: $.param({ online: false}) });
        this.render();
        this.listenTo( this.collection, 'reset', this.render );
    },
    render: function() { /// },
    renderRegion: function( item ) { /// },
    searchAssessors: function( e ) {
        e.preventDefault();
        this.collection.remove();
        console.log("EVENT");
    }
});

这是我的HTML表单:

<form id="form-search-assessors" class="form-horizontal" role="form">
    .........
    <input id="search-assessors-button" class="btn btn-lg btn-success btn-block" type="submit" value="Search" />
    <!--<button id="search-assessors-button" class="btn btn-lg btn-success btn-block" type="submit">Search</button>-->
</form>

我给searchAssessors设置了断点,但它不起作用。此外,我在控制台中没有看到任何消息。

尝试将事件更改为"submit #form-search-assessors": "searchAssessors"

您初始化视图了吗?,由于这只是您代码中的一个片段,我删除了一些内容和注释,所以这应该可以工作。

HTML

<div id="assessors">
    <form id="form-search-assessors" class="form-horizontal" role="form">
       <input id="search-assessors-button" class="btn btn-lg btn-success btn-block" type="submit"            value="Search" />
   </form>
<div>

JS-

AssessorsCollectionView = Backbone.View.extend({

    el: '#assessors',
    tagName: 'div',
    events:{
        'submit form': 'searchAssessors'
    },
    initialize: function() {
        this.render();
    },
    render: function() {  },
    searchAssessors: function( e ) {
        e.preventDefault();
        console.log('EVENT');
    }
});
view = new AssessorsCollectionView();

我的问题的解决方案:

$( "form#form-search-assessors" ).submit($.proxy(function(e) {
    e.preventDefault();
    console.log(this);
    this.collection.fetch({reset: true, data: $.param({ online: true}) });
    this.render();
}, this));
