我想保存一個模型,我可以保存第一個模型罰款,但是如果我保存一個模型,然後另一個直 - 事後得到以下錯誤,骨幹 - 未捕獲TypeError:對象[對象對象]沒有方法'調用'
Uncaught TypeError: Object [object Object] has no method 'call'
什麼會導致此錯誤?
我保存的代碼如下所示,
GroupModalHeaderView.prototype.save = function(e) {
var $this = this;
this.collection = new app.GroupCollection();
if(this.$("#group-name").val() !== "") {
this.collection.add(this.model,{
merge: true
});
}
this.model.save({
name: this.$("#group-name").val(),
async: false,
wait: true
}, {
success: function() {
var GroupList = new app.GroupListView({
model: $this.model,
collection: $this.collection
});
var modal = new app.GroupModalView({
model: $this.model,
collection: $this.collection
});
$this.collection.on("change", GroupList.render(), this);
$this.collection.on("change", modal.render(), this);
//return $this.cancel();
}
});
};
而且我的模型代碼看起來像這樣,
(function() {
var Group, GroupSearchModel,
__hasProp = {}.hasOwnProperty,
__extends = function(child, parent) { for (var key in parent) { if (__hasProp.call(parent, key)) child[key] = parent[key]; } function ctor() { this.constructor = child; } ctor.prototype = parent.prototype; child.prototype = new ctor(); child.__super__ = parent.prototype; return child; };
Group = (function(_super) {
__extends(Group, _super);
function Group() {
return Group.__super__.constructor.apply(this, arguments);
}
Group.prototype.urlRoot = config.base + "api/group/groups";
Group.prototype.defaults = {
user_id: "",
name: "New Group",
email: "",
url: "",
telephone: "",
mobile: "",
fax: "",
people: ""
};
Group.prototype.idAttribute = "id";
return Group;
})(app.BaseModel);
GroupSearchModel = (function(_super) {
__extends(GroupSearchModel, _super);
function GroupSearchModel() {
return GroupSearchModel.__super__.constructor.apply(this, arguments);
}
return GroupSearchModel;
})(app.BaseModel);
this.app = window.app || {};
this.app.Group = Group;
this.app.GroupSearchModel = GroupSearchModel;
}).call(this);
我假設是有事情做與.call(this)
在結束我的模型?
基於您的代碼,你真的需要閱讀這篇文章如何組織骨幹視圖和模型:http://alexkinnee.com/2013/12/optimal-use-of-backbone-js-model -events-and-mvc-structure/ :) –
