Textarea突出重点 [英] Textarea highlight on focus

问题描述

我试图在获得焦点时在textarea中突出显示所有内容。目前，一旦获得焦点，内容将突出显示，但会立即失去它。

I'm trying to have all the contents in a textarea highlight when it gains focus. Currently, as soon as it gains focus the contents will be highlighted but it immediately loses it.

这就是我正在使用的：

<textarea onfocus="this.select()" readonly>Test</textarea>

推荐答案

您已阻止mouseup事件，因为它在焦点设置并取消选择内容后触发

You have prevent the mouseup event as well, as it fires after the focus is set and deselects the contents

<textarea onfocus="this.select()" onmouseup="return false;" readonly="readonly">Test</textarea>
