问题描述

大家好



我想通过Javascript向asp TreeView添加节点。任何人都可以给我一个例子

Hi guys

I want to add nodes to asp TreeView by Javascript. Can any one give me an example

推荐答案

从JavaScript的角度来看，没有 TreeView 这样的东西。你只需要将一些元素添加到另一个DOM元素，也许是一个文本节点，并设置它的一些属性。



所以，你所需要的只是减少到以下功能：

https://developer.mozilla.org / en-US / docs / Web / API / Document / createTextNode [ ^ ]，

https://developer.mozilla.org/en-US/docs/Web/API/Document/createElement [ ^ ]，

https://developer.mozilla.org/en-US/docs/Web/API/Node/appendChild [ ^ ]，

https://developer.mozilla.org/en-US/docs/Web/API/Element/setAttribute [ ^ ]。



我希望我没有错过任何东西;这就是你所需要的一切。

From the JavaScript standpoint, there is no such thing as TreeView. You just need to add some element to another DOM element, and perhaps a text node, and set some of its attributes.

So, all you needs are reduced to the following functions:
https://developer.mozilla.org/en-US/docs/Web/API/Document/createTextNode[^],
https://developer.mozilla.org/en-US/docs/Web/API/Document/createElement[^],
https://developer.mozilla.org/en-US/docs/Web/API/Node/appendChild[^],
https://developer.mozilla.org/en-US/docs/Web/API/Element/setAttribute[^].

I hope I did not miss anything; this is really all you need.
