[英]How can I focus on an input field when a phonegap page loads?
I would like to focus on a text input in a PhoneGap application when the page loads. 我想在页面加载时专注于PhoneGap应用程序中的文本输入。 I have tried the MooTools version
$('entry').focus();
我尝试过MooTools版本
$('entry').focus();
and document.getElementById('entry').focus()
when the DOM is ready. 当DOM准备就绪时,
document.getElementById('entry').focus()
。
This works fine when the HTML page is viewed in a normal web browser, but in the iPhone simulator running PhoneGap, it doesn't work. 当在普通的Web浏览器中查看HTML页面时,这可以正常工作,但在运行PhoneGap的iPhone模拟器中,它不起作用。
Is there a way to focus on a form field for iPhones that forces the virtual keyboard to appear? 有没有办法专注于强制虚拟键盘出现的iPhone的表单字段?
As of iOS 6, the UIWebView class has a property called "keyboardDisplayRequiresUserAction". 从iOS 6开始,UIWebView类具有一个名为“keyboardDisplayRequiresUserAction”的属性。 If you want to programmatically focus text form elements, set this to false via your phonegap config.xml:
如果要以编程方式聚焦文本表单元素,请通过phonegap config.xml将其设置为false:
<preference name="KeyboardDisplayRequiresUserAction" value="false" />
The default value is true. 默认值是true。

As far as I know, this is an intentional limitation of WebKit on both iPhone and Android; 据我所知,这是iPhone和Android上WebKit的故意限制; only a user touch action can trigger a keyboard.
只有用户触摸动作才能触发键盘。 I'm still trying to concoct a workaround, but I'm not very optimistic.
我仍在尝试制定一个解决方法,但我不是很乐观。
