當要渲染檢視,模板建立標記可重複使用副本,並提供了存取範例資料。
view.template(data)
<!DOCTYPE html> <head> <title>View Example</title> <script src="https://code.jquery.com/jquery-2.1.3.min.js" type="text/javascript"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/underscore.js/1.8.2/underscore-min.js" type="text/javascript"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/backbone.js/1.1.2/backbone-min.js" type="text/javascript"></script> </head> <body> <div id="mydiv"></div> <script type="text/javascript"> //'ViewDemo' is a name of the view class var ViewDemo = Backbone.View.extend({ //'el' uses '#mydiv' as the view reference el: $('#mydiv'), //'template' provides access to instance data when rendering the view template: _.template("Welcome to <%= name %>"), //This function is called when the view is instantiated initialize: function(){ this.render(); }, //'render' provides the logic required to construct the view render: function(){ //'$el' is cached object that push the content defined within it and //display the value of 'name' when 'template' access the data this.$el.html(this.template({name: 'Yiibaipoint...!'})); } }); //'myview' is an instance of the 'ViewDemo' class var myview = new ViewDemo(); </script> </body> </html>
讓我們進行以下步驟來看看上面的程式碼工作:
儲存上述程式碼到檔案template.html
在瀏覽器開啟這個HTML檔案。
