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).
感谢您的帮助
很遗憾,您无法在 Mobile Safari 中执行此操作.我相信 Apple 选择限制这种情况发生,因为当您访问某些网站(例如 Google)时,搜索字段会立即获得焦点.如果用户访问的每个站点都弹出键盘,这对用户来说将非常烦人.在桌面设备上这种行为无关紧要,但在移动设备上却非常明显.
Unfortunately you can't do that in Mobile Safari. I believe Apple chose to restrict this from happening because when you visit some sites, like Google for example, the search field gets focused immediately. This would be extremely annoying for users if every site they went to, the keyboard popped up. On Desktop this behaviour doesn't matter but on mobile devices it's very noticeable.
