问题描述

首先，我知道 contenteditable 仅适用于 iOS 5，我已经说明了这一点 - 我们为 iOS 5 的用户提供了允许使用 contenteditable 粘贴富文本的功能.到目前为止，此功能非常有效，我要做的就是当视图出现时将 contenteditable 字段设置为活动(预先选择它)，以便键盘出现并且用户可以立即开始输入.这是我用于 UIWebView 的本地 html 文件

First of all I know contenteditable is only iOS 5 I have accounted for this - we are giving users with iOS 5 a feature to allow Rich Text pasting using contenteditable. This feature works great so far all I want to do is when the view appears to set the contenteditable field as active (pre-select it) so that the keyboard appears and the user can begin typing right-away. Here is the local html file I am using for the UIWebView

<html>
    <body>
        <div id="content" contenteditable="true" style="font-family: Helvetica">PLACEHOLDER</div>
    </body>
</html>

我已经尝试使用一些 javascript 来完成此操作，使用我找到的用于预选文本输入的教程.即使我尝试切换到文本输入字段进行测试，我也无法让它工作.这可能是由于我对 javascipt 缺乏经验，所以如果这是解决方案，请明确说明(因为我完全不熟悉 javascript).

I have already tried using some javascript to accomplish this using tutorials that I found for preselecting a text input. I could not get this to work, even when I tried to switch to a text input field for testing. This is probably due to my inexperience with javascipt so if that is the solution please be explicit (as I am completely unfamiliar with javascript).
