Javascript / Ember - 切换变量的布尔值

Question

I know that there is the .set() method to set a boolean to true or false but I want to know if there a method like .set() except it Toggles the value of a boolean.

In this case the boolean isEditing is being set to 'true'.

isEditing:false,
actions: {
  edit: function(category){
    category.set('isEditing', true);
    console.log(this.get('isEditing'))
  },
}

Here is the html

{{#if isEditing}}
  <div class="category-text"> 
    {{view Ember.TextField valueBinding=name action="turnOffEditMode"}}
  </div>
{{else}}
  <div class="category-text"> 
    {{#linkTo 'category' this}}
      {{name}}
    {{/linkTo}}
  </div>
{{/if}}

Answer 2

isEditing:false,
actions: {
    edit: function(category){
        category.set('isEditing', !category.isEditing);
        console.log(this.get('isEditing'))
    }
    toggleEditing : function(category){
    }
}

Toggling the boolean value is what you need. Or yu can change your function like below.

isEditing:false,
actions: {
    toggleEditing : function(category){
        category.set('isEditing', !category.isEditing);
        console.log(this.get('isEditing'));
    }
}

Answer 3

@gravityplanx's answer is great.

I just want to add that this methodology works beyond the controller as well.

For example, if my Model has a Post object, I can update it from the controller. I just have to pass the object into a controller action.

switch_readiness(post) {
    post.toggleProperty('isPublishReady');
}
