淘汰赛数据绑定重置 [英] Knockout databind reset

问题描述

我在网络表单上使用剔除数据绑定.目前，我有一个重置功能，可在重新加载原始数据以清除表单之前使用它.我有60多个领域需要清除，每个人做起来都是一件痛苦的事情.有没有办法一次清除所有敲除绑定?目前，我使用的是以下内容:

I use knockout databinds on webforms. Currently I have a reset function that is used before re-loading original data to clear the form. I have over 60 fields that I need to clear and doing each one individual is a pain. Is there a way to clear all knockout bindings at once? Currently what I use is below:

self.parentObject.somefield('');
self.parentObjectAddress.street1('');
etc 
etc

-更新1-

为澄清起见，我所有的字段都是parentObject的一部分.例子

To add clarification all my fields are part of a parentObject. Example

self.parentObject.fieldName

我要做的是清除parentObject的所有子对象.

What I am looking to do is clear all children of the parentObject.

推荐答案

我会考虑另一种方法.为什么不重置"对象本身，为什么不创建一个新对象并将旧对象扔掉呢?您应该已经具有用于创建对象的代码.如果您在顶层有data-bind="with: someObject"(也许是<form>标记?)，则用新的干净"对象实例替换someObject(假设它是可观察的).

I would consider a different approach. Rather than "resetting" the object itself, why not create a new object, and throw the old one away? You should already have code to create the object. If you have a data-bind="with: someObject" at the top level (maybe the <form> tag?) then replace someObject (assuming it's observable) with a new, "clean" instance of the object.
