我正在学习
backbone.js,而且我刚开始学习.我想通过
underscore模板方法添加模板,但它不适用于我.我搜索了这个错误,但无法自己解决.如果没有显示模板,我该如何前进？需要一些帮助的人.
这是代码(此代码来自addyosmani的书籍骨干基础知识)：
<!DOCTYPE html> <html> <head> <Meta charset="utf-8"> <title>testing</title> </head> <body> <script src="scripts/jquery.js"></script> <script src="scripts/underscore.js"></script> <script src="scripts/backbone.js"></script> <script> var TodoView = Backbone.View.extend({ tagName: 'li',// Cache the template function for a single item. todoTpl: _.template( $('#item-template').html() ),events: { 'dblclick label': 'edit','keypress .edit': 'updateOnEnter','blur .edit': 'close' },// Re-render the titles of the todo item. render: function() { this.$el.html( this.todoTpl( this.model.toJSON() ) ); this.input = this.$('.edit'); return this; },edit: function() { // executed when todo label is double clicked },close: function() { // executed when todo loses focus },updateOnEnter: function( e ) { // executed on each keypress when in todo edit mode,// but we'll wait for enter to get in action } }); var todoView = new TodoView(); // logs reference to a DOM element that cooresponds to the view instance console.log(todoView.el);
