骨幹集合布爾型翻轉

Question

當我正在偵聽集合中模型的布爾屬性的更改事件時，如何處理該事件以在集合中的所有其他模型上關閉布爾。

Answer 1

試試這個：

// in your model 
yourModel.on('change:yourBooleanAttribute', yourCollection.setAllButCurrent); 

// and in your collection 
setAllButCurrent: function(changedModel, value, options) { 
    // here you can iterate through `this.models` and for each model 
    // if it's `id` differ from changedModel id, change it's `yourBooleanAttribute` 
    // to the opposite value of `value` 
}
