jQuery移动设备扩展 [英] JQuery Mobile Device Scaling
问题描述
我正在使用JQuery Mobile，但无法将浏览器缩放到iPhone.
I am using JQuery Mobile and I am having trouble with the scaling from my browser to my iPhone.
当我将其加载到浏览器(野生动物园)中时，它会缩小和扩展.但是，当我将其加载到iPhone上时，它无法缩放.它可以让您在不应该的时候向左和向右滚动.
When I load it on a browser (safari) it shrinks and expands just fine. However when I load it on my iPhone it doesn't scale. It allows you to scroll left and right when it shouldn't.
是否应该添加一些内容以使其缩小以识别它是移动设备.
Is there something I am supposed to add to make it scale down on recognize that it's a mobile device.
这是我当前的html.
Here is my current html.

推荐答案
我在iPhone视口和JQuery-Mobile上也遇到了问题，最终得到了以下解决方案.
I had problems with the iPhone viewport and JQuery-Mobile as well, I ended up with the following solution.
- 添加一个将高度和宽度设置为device-height/device-width的元标记(您可以通过将最大比例更改为大于1来允许用户缩放，但是在以下示例中禁用了缩放，相信Mobile Safari最多可以输入10):
<meta name="viewport" content="height=device-height,width=device-width,initial-scale=1.0,maximum-scale=1.0" >
- 当用户更改iPhone上的方向时，我注意到重新缩放和添加空格后出现了一些奇怪的行为，所以我使用了以下代码:
//check the navigator.userAgent string to detect if the user is using an iPhone
if (navigator.userAgent.match(/iPhone/i)) {
//cache the viewport tag if the user is using an iPhone
var $viewport = $('head').children('meta[name="viewport"]');
//bind an event handler to the window object for the orientationchange event
$(window).bind('orientationchange', function() {
if (window.orientation == 90 || window.orientation == -90 || window.orientation == 270) {
//landscape
$viewport.attr('content', 'height=device-width,width=device-height,initial-scale=1.0,maximum-scale=1.0');
} else {
//portrait
$viewport.attr('content', 'height=device-height,width=device-width,initial-scale=1.0,maximum-scale=1.0');
}
//trigger an orientationchange event on the window object to initialize this code (basically in-case the user opens the page in landscape mode)
}).trigger('orientationchange');
}
事件处理程序中的if/then语句检查用户更改了哪个方向(90，-90和270都是我为横向所见的值)，而$viewport.attr('content',...行仅切换了高度和视口标记中的宽度值.
The if/then statement in the event handler checks for which orientation the user has changed to (90, -90, and 270 are all values I've seen for landscape) and the $viewport.attr('content',... lines just switch the height and width values in the viewport tag.
