从Backbone.js的模型删除属性 [英] Remove an attribute from a Backbone.js model

问题描述

有没有一种方法，以消除从骨干模型属性？

Is there a way to remove an attribute from a Backbone model?

原因是我是传上来就​​节省执行某些操作额外的数据，但这些数据被自动添加到我的模型

Reason being is I pass up extra data on save to perform certain actions, but then that data gets automatically added to my model

文档说不要直接编辑model.attributes，所以唯一的其他方法我认为这样做将是使用的设置方法，并设置为空的属性，但不是理想

The documentation says to not edit the model.attributes directly, so the only other method I see to do this would be to use the set method and set the attribute to null, but that is not ideal

var myModel = new Model()
myModel.save({name:'Holla', specialAttr:'Please Remove me'})
myModel.set({tempAttr:null})

if(myModel.attributes['specialAttr'] == null){
    alert("Model does not have a specialAttr")
}

我也试着从属性的属性删除它，但它并没有真正将其删除。

I've also tried removing it from the attributes property, but it doesn't really remove it.

推荐答案

您是否在寻找 model.unset ？

从内部属性哈希删除它删除属性。
  触发一个change事件，除非是沉默作为一个选项过去了。

Remove an attribute by deleting it from the internal attributes hash. Fires a "change" event unless silent is passed as an option.

您可以在这里找到文档。

You can find the documentation here.
