Firefox 和 Angular:Textarea 占位符直到第一个焦点才出现 [英] Firefox and Angular: Textarea placeholder doesn't appear until first focus

问题描述

我有一个超级简单的 Angular 应用:

<ul>
<textarea placeholder='Hello'></textarea>

就是这样.没有 JS/CSS.

在 FF(OSX 上的 34.0)中，Textarea 中的占位符在 textarea 聚焦之前不会显示.

到目前为止我发现了什么:

• 它仅在 textarea 上.文本输入没问题.
• 仅当它在子 $scope 内时.如果 ng-if 不存在，问题就会消失.

试试看这里.

我没有想法了.任何帮助将不胜感激！:)

解决方案

这是 Gecko 中的一个错误，已解决:https://bugzilla.mozilla.org/show_bug.cgi?id=1088158

修复程序应该会在几个月内稳定发布，但同时，对于给您带来的不便，我们深表歉意.

I have a super-simple Angular app:

<div ng-app>
  <ul>
    <li ng_if='true'>
      <textarea placeholder='Hello'></textarea>
    </li>
  </ul>
</div>

That's it. No JS / CSS.

In FF (34.0 on OSX), the placeholder in the Textarea will not show up until the textarea is focused.

What I've discovered thus far:

• It's only on textarea. Text inputs are fine.
• It's only when it's within a child $scope. If the ng-if wasn't there, the issue would disappear.

Play around with it here.

I'm out of ideas. Any help would be super appreciated! :)
