何らかの理由で、このエラーが発生し続けます (添付のスクリーンショットを参照)。を追加しようとしまし_.bindAll(this);
たが、最新バージョンの backbonejs を使用するようにコードをアップグレードしようとしました。まだ運がありません。
誰かがこれについて私を助けることができますか?
var app = app || {};
(function ($) {
'use strict';
app.EmployeeView = Backbone.View.extend({
el: '#container',
model: app.Employee,
events: {
'click #save' : 'saveEntry'
},
initialize: function(){
console.log('Inside Initialization!');
this.$empName = this.$('#txtEmpName');
this.$department = this.$('#txtDepartment');
this.$designation = this.$('#txtDesignation');
this.listenTo(app.employees, 'add', this.addEmployee);
app.employees.fetch();
console.log('End of Initialization!');
//this.render();
},
render: function () {
console.log('Inside Render!!');
console.log(this.model);
this.$el.html(this.template(this.model.toJSON()));
console.log('Inside End of Render!!');
return this;
},
newAttributes: function(){
return{
empName: this.$empName.val(),
department: this.$department.val(),
designation: this.$designation.val()
};
},
saveEntry: function(){
console.log('Inside SaveEntry!');
//console.log(this.newAttributes());
console.log('this.model');
console.log(app.Employee);
//app.employees.create(this.newAttributes());
app.Employee.set(this.newAttributes());
app.employees.add(app.Employee);
console.log('After SaveEntry!');
},
addEmployee: function (todo) {
var view = new app.EmployeeItemView({ model: app.Employee });
$('#empInfo').append(view.render().el);
}
})
})(jQuery);
「collections/employees.js」のコード
var app = app || {};
(function (){
console.log('Inside collection');
var Employees = Backbone.Collection.extend({
model: app.Employee,
localStorage: new Backbone.LocalStorage('employee-db')
});
app.employees = new Employees();
})();
「model/employee.js」のコード
var app = app || {};
(function(){
'use strict';
app.Employee = Backbone.Model.extend({
defaults: {
empName: '',
department: '',
designation: ''
}
});
})();
