好吧，所以我试图将一个视差网站移植到Wordpress，到目前为止它只给我带来了麻烦。现在我终于把它全部用在桌面浏览器上，但在移动浏览器上却产生了各种各样的问题。如果有人可以告诉我如何禁用我的脚本的这一部分（使用Stellar和iScroll）在移动浏览器上显示，或者更好，也许你明白我为什么会遇到这么多问题。无论哪种方式，我都会非常感谢一些建议，因为jQuery / Javascript对我来说非常陌生。 TIA！

我在这里找到了这个代码，用于检测它是否是javascript中的移动设备
window.mobilecheck = function() {
var check = false;

return check; }
所以你可以使用这个功能来检测一个手机，如果是的话，在（isMobileWebkit）中添加我认为禁用视差效果的代码，所以代码看起来像这样
if(window.mobilecheck())
{
iScrollInstance = new iScroll('scroller');
jQuery('#wrapper').stellar({
parallaxBackgrounds:false,
scrollProperty: 'transform',
positionProperty: 'customPositionTransform',
hideDistantElements: false,
horizontalScrolling: false,
verticalOffset: verticalOffset
});
}
这未经过测试我希望它有效

UA检查不是最好的主意，因为每隔一段时间就会创建新的移动设备/点燃/黑莓/ Firefox-os-phones / Ubuntu-phone等。任何设备使用者名单都会很快过时。
如果您想关闭基于触控设备的某些效果，可能会出现这种情况：How to check browser for touchstart support using JS/jQuery?
基本上你可以使用
if (document.createTouch) {
//mobile code
} else {
//desktop, non-touch code
}
