我想让我的视图来获取一个属性的值 [英] I want my view to grab the value of an attribute

问题描述

要在docController中执行此操作，将被调用为

  var docTemplateID = this.get（'docTemplateID'）; 
  

或/和

  var model = this.get（'model'）; 
  

但是当我在docView中做同样的事情时，它不会获取当前文档的docTemplateID。

以下是查看中使用的功能

  VpcYeoman.DocView = Ember.View.extend（{
 toggleLetterSwitch：false，
 togglePermitSwitch：false，
 templateName：'doc'，
 willInsertElement：function （）{
 var model = this.get（'model'）; 
 var docTemplateID = this.get（'docTemplateID'）; 
 if（docTemplateID == 2）{
 this.set（'toggleLetterSwitch'，true）; 
 this.set（'togglePermitSwitch'，false）; 
 console.log（'docTemplateID equals 2'）; 
} else {
 this.set（'toggleLetterSwitch'，false）; 
 this.set（'togglePermitSwitch'，true）; 
 console.log（this.get（'toggleLetterSwitch'））; 
 console.log（'docTemplateID else 1'）; 
 } 
} 
}）; 
  

路由和控制器是标准的，所以我没有链接它们，但是让我知道是否应该。

解决方案

控制器作为属性添加到您的视图中，您可以使用链接来抓取它们。

  this.get（'controller.docTemplateID'）;

My view is not grabbing the value of an attribute I set for the model.

To do this in the docController would be called like

var docTemplateID = this.get('docTemplateID'); 

or/and

var model = this.get('model');

but when I do the same thing in the docView, it does not grab the value of the current doc's docTemplateID.

Here is the function used in the View

VpcYeoman.DocView = Ember.View.extend({ 
    toggleLetterSwitch: false,
    togglePermitSwitch: false,  
  templateName: 'doc',
  willInsertElement: function() {
      var model = this.get('model');
      var docTemplateID = this.get('docTemplateID');
      if ( docTemplateID == 2) {
        this.set('toggleLetterSwitch', true);
        this.set('togglePermitSwitch', false);
        console.log('docTemplateID equals 2');
      } else {
        this.set('toggleLetterSwitch', false);
        this.set('togglePermitSwitch', true);
        console.log(this.get('toggleLetterSwitch'));
        console.log('docTemplateID else 1');
      }
  }
});

The routes and controllers are standard so I didn't link them, but let me know if should.

解决方案

The controller is added as a property on your view, and you can grab them using chaining.

this.get('controller.docTemplateID');
