iOS 7 - 固定页脚工具栏在虚拟键盘上中断 [英] iOS 7 - Fixed footer toolbar breaks on virtual keyboard

问题描述

我创建了一个在浏览器中运行并提供聊天支持的应用程序。这适用于桌面和移动设备，并且显示为固定的页脚。

I have created an application which runs in the browser and provides chat support. This is for desktop and for mobile and appears as a fixed footer.

在桌面设备上，一切正常，看起来很棒，但是当它出现在移动设备上时，我看到一个奇怪的问题。

On desktop, everything is working and looking great, but when it hits mobile I am seeing an odd issue.

当我不在页面顶部并打开键盘时，一切正常：

When I am not at the top of the page and open the keyboard, it all works okay:

但如果我靠近页面顶部，工具栏会断开并显示页面的一半：

but if I am near the top of the page the toolbar breaks and appears half way up the page:

我找到了以下链接，其他人提到它，但我无法隐藏页脚，因为我需要它显示：
http://forum.jquery.com/topic/how-to-set-页脚固定在底部 - 甚至是虚拟键盘 - 打开

I found the following link where someone else mentions it but I can not hide the footer as I need it shown: http://forum.jquery.com/topic/how-to-set-footer-fixed-at-bottom-even-if-virtual-keyboard-is-open

任何关于如何解决这个问题的建议都会很有帮助se，我读到iOS增加了对固定位置的支持，但在这种情况下似乎被打破了（从网页顶部打开虚拟键盘）。

Any advice on how to fix this would be great please, I read that iOS added support for fixed position but seems to be broken for this case (opening the virtual keyboard from the top of the webpage).

这是我的代码：

#gc_toolbar_layout {
    ...
    position: fixed;
    word-break: keep-all;
    word-break: break-word;
    -webkit-box-sizing: border-box;
    -moz-box-sizing: border-box;
    -ms-box-sizing: border-box;
    box-sizing: border-box;
}

谢谢。

推荐答案

令人难以置信的hacky修复：

Incredibly hacky fix:

$(document).on('focus', 'textarea', function() {
    $("#gc_chat_layout").css({position: 'relative', float: 'right', bottom: 'auto'});
    $(document).scrollTop($(document).scrollTop());
});
$(document).on('blur', 'textarea', function() {
    $("#gc_chat_layout").css({position: 'fixed', float: 'none', bottom: '0'});
});

当我们不在页面顶部时，我们才看到上述问题。这基本上会让你立即进入页面顶部。

We were only seeing the above issue when we were not at the top of the page. This basically throws you to the top of the page instantly.

我们添加了一些javascript代码来处理这个问题，同时保存你在变量中的旧位置，并将你移回曾经做过。

We added some javascript code to handle this as well by saving your old position in a variable, and moving you back there once done.
