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);
