我将此添加到我的主干扩展.js 文件中，该文件与主干-min.js 位于同一文件夹中......
_.extend(Backbone.View.prototype, {
getFormData: function(form) {
var unindexed_array = form.serializeArray();
var indexed_array = {};
$.map(unindexed_array, function(n, i){
indexed_array[n['name']] = n['value'];
});
return indexed_array;
}
});
但是，当我在视图代码中调用 this.getFormData 时，我得到一个方法未定义的错误。我错过了什么？谢谢你的帮助！
编辑：这是我的看法。我必须取消注释 getFormData 方法才能使其工作。否则它看不到 getFormData ......
