添加, 在 Ember 视图完成时删除 cs 类
原标题:Add, remove css classes while Ember view getting rendered

如何添加、 删除和更改根据内容 Binding 中的值而每做一次的模组元素 cs 类别?

在“插入元素”中做类似下面的工作,但到时候根据控制器的内容值增加了 cs 类,视图元素附在视图中,因此 cs 没有得到应用。

还有什么其他方法可以让我们在视觉元素形成时 完成这个任务吗?

didInsertElement: function() {
      this._super();
    var personStr= this.get("content").person;
       if(personStr==1){
            this.$("img").addClass("add-person");
            this.$("img").removeClass("view-person");
            this.$("img").removeClass("edit-person");

您可以使用 Ember.collectionView , 并指定取决于 content 类中的 consist 类中的 NameBintings 。 见 http://docs.emberjs.com/#doc=Ember.View&src=false" rel="nofol=nfolpol" 文档 , 节 HTML 类属性 。

例如,http://jsfidle.net/pangratz666/b4xGP/ :

Ember.CollectionView.create({
    content: [{name:  Brunö }, {name:  Alfred }, {name:  Hansi }],

    itemViewClass: Ember.View.extend({
        templateName:  item ,
        classNameBindings:  beginsWithA .w(),

        beginsWithA: function() {
            var name = this.getPath( content.name );
            if (!Ember.empty(name)) {
                return name.indexOf( A ) === 0;
            }
        }.property( content.name )
    })
}).append();​
