如何在Nativescript中获取elementById? [英] How to get elementById in Nativescript?

问题描述

我正在将nativescript与vue.js一起使用，并且正在尝试执行类似DOM操作的操作.这是我的模板中的示例代码:

I'm using nativescript with vue.js and I'm trying to do something like DOM operation. This is sample code from my template:

<Label textWrap="true">
    <FormattedString id="formString"
      backgroundColor="yellow"
      effectiveHeight="100"
      effectiveWidth="100%">
      <Span text="This text has a " /> 
    </FormattedString>
 </Label>

我想通过他的ID- formString 获得标签元素 FormattedString 在javascript中是这样的:

I want to get tag element FormattedString by his id - formString In javascript is like this:

让fs = doument.getElementById('formString');
如何在Nativescript-Vue中做到这一点?我知道有一个库 nativescript-dom ，但是我不想使用整个库，用于简单的getById.

let fs = doument.getElementById('formString');
How can I do this in Nativescript-Vue? I know that there is library nativescript-dom, but I don't want to use whole library for simple getById.

推荐答案

使用 Label.getViewById("formString")访问FormattedString的属性.

Use Label.getViewById("formString") to access the attributes of FormattedString.

getViewById 与javascript getElementById最接近

getViewById is the nearest equivalent to the javascript getElementById
