EmberJS 组件自定义类名

2018-01-04 11:22 更新

描述

你可以通过在Ember.Component类中将其classNames属性设置为字符串数组来为组件的元素指定类名。

语句

Ember.Component.extend({
   classNames: ['Class Name']
});

例子

<!DOCTYPE html>
<html>
   <head>
      <title>Emberjs Customizing Class Names</title>
      <!-- CDN's -->
      <script src="https://cdnjs.cloudflare.com/ajax/libs/handlebars.js/3.0.1/handlebars.min.js"></script>
      <script src="https://code.jquery.com/jquery-2.1.3.min.js"></script>

   </head>
   <body>
      <script type="text/x-handlebars" data-template-name="application">
         <h3>Customizing the class names using 'classBindings'</h3>
         {{#each}}
            {{my-tag title=title isChecked=isChecked}}
         {{/each}}
      </script>

      <script type="text/x-handlebars" data-template-name="components/my-tag">
         {{input type="checkbox" checked=isChecked}} {{title}}
      </script>

      <script type="text/javascript">
         App = Ember.Application.create();

        //myvalues is an array
         myvalues = [{
            title: "Tutorialspoint",
            //displays checked checkbox
            isChecked: true
           },{
            title: "Simple easy learing",
            //displays uncheked checkbox
            isChecked: false
         }];

         App.ApplicationRoute = Ember.Route.extend({
            model: function() {
               //return the array values
               return myvalues;
            }
         });

        App.MyTagComponent = Ember.Component.extend({
           //specifying the class name as 'isChecked'
           classNameBindings: ['isChecked']
        });
     </script>
  </body>
</html>
