如何添加preventDefault()backbone.js

Question

如何<button>在事件中添加preventDefault()？我下面的内容不起作用..谢谢

var View = Backbone.View.extend({

    initialize: function () {
        //console.log('initializing ' + this.options.blankOption);
        this.template = $('#list-template').children();
    },
    el: '#container',
    events: {
        'click button' : 'render'
    },
    render: function(){

        this.events.preventDefault(); // not working ????

        var data = this.model.get('data');

        $.each(data,function (i,v) {
            console.log(data.text + " " + data.href);
        });

    }
});

this.events不是事件对象.所以它不起作用

试试这个:

render: function(event){
    event && event.preventDefault();

    var data = this.model.get('data');

    $.each(data,function (i,v) {
        console.log(data.text + " " + data.href);
    });
}
