## Instructions
|
||
|
||
文本组件。用于包裹文本内容。
|
||
|
||
在app-uvue和app-nvue中，文本只能写在text中，而不能写在view的text区域。
|
||
|
||
虽然app-uvue中写在view的text区域的文字，也会被编译器自动包裹一层text组件，看起来也可以使用。但这样会造成无法修改该text文字的样式，详见uvue的 样式不继承 章节
|
||
|
||
### Syntax
|
||
|
||
- 使用 `<text />`（或 `<text></text>`，当需要包裹子节点时）。
|
||
- 遇到平台差异时，建议使用条件编译（`#ifdef / #endif`）显式处理。
|
||
|
||
