這些屬性雜湊為HTML DOM元素上檢視的el 屬性將被設定(ID,類,資料屬性等), 或者一個函式,返回這樣的雜湊值。
view.attributes
<!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="myapp"></div> <script type="text/javascript"> //'MyModel' is a model name and includes default value var MyModel = Backbone.Model.extend({ defaults: { name: "sachin tendulkar" } }); //'ViewDemo' is a name of the view class var ViewDemo = Backbone.View.extend({ //This function is called when the view is instantiated initialize: function () { document.write("View is initialized..."+"<br>"); //gets site name by using model instance document.write("The site is: ",this.model.get("Site")+"<br>"); document.write("The tag name is: ",this.tagName+"<br>"); document.write("The class name is: ",this.className); }, }); $(function () { //'mymodel' is an instance of the model var mymodel = new MyModel({ Site: "YiiBai" }); //'myview' is an instance of the view class with attributes model, tagName, className var myview = new ViewDemo({ model: mymodel, tagName: "mytag", className: "myclass"}); }) </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attributes.html
在瀏覽器開啟這個HTML檔案。
