jos*_*sea 19 javascript css safari css-selectors ios8
编辑:我向Apple报告了这个错误,现在已关闭,在测试版iOS 9.0(13A4254v)上测试并正常工作.
编辑以获得更好的解释:
我在网页上有很多文章,都包含在div(列)中.这些文章有一个绝对位置,固定宽度和高度的类.
有一个按钮可以应用: - 一个translate3d到包装器/列 - 一个window.history.pushState
所有样式都正确应用于所有文章,但是当我按下按钮并在pushState之后,所有/部分nth-child()样式都没有正确应用(左,上和宽).如果我将:nth-child()更改为:nth-of-type(),则在pushState之后正常工作.
当safari确定激活切换到阅读器模式的可能性时,按下单击按钮并影响到translate3d元素(硬件加速)后,问题似乎是可见的.
它发生在使用iPad2,iPad3视网膜和4的Safari iOS8上.它不会发生使用iPad迷你视网膜.使用iOS7之前所有工作正常,但没有使用iOS8.

你有过这样的经历吗？

确实nth-child不适用于IOS8.
切换nth-of-type为我做了伎俩.
它得到了很好的支持https://developer.mozilla.org/en-US/docs/Web/CSS/:nth-of-type
如果您不想冒险,可以按照以下方式检测IOS 8.
function isIOS8() {
if ("600.1.4" == $.browser.version || ~navigator.userAgent.indexOf('OS 8_') ){
return true;
}
return false;
}
var i=0,
$el = $('ul.poll');
if( isIOS8() ){
$el.find(' li:nth-of-type(' + (i + 1) + ')').text('my first Child');
}else{
$el.find('.choice:nth-child(' + (i + 1) + ')').text('my first Child');
}
