Question

我为我的应用程序发出了这个声明来检测移动设备，但我想在if else语句中使用JQuery。我不确定这是否可行。

    .gpu {
    width: 33%;
    margin-bottom: .25%;
    float: left;
}

.webcam {
    width: 16.25%;
    margin-right: .5%;
    float: left;
    clear: both;
}

.combs {
    width: 16.25%;
    float: left;
}

.monitor {
    width: 33%;
    float: left;
}

.kb {
    width: 16.25%;
    float: right;
}

.headset {
    width: 16.25%;
    margin-right: .5%;
    float: right;
}

.mobo {
    width: 33%;
    margin-top: .25%;
    float: right;
    clear: right;
}

有人可以按照if中使用JQuery的方式更正我的代码，或者告诉我这是否可能/错误？

亲切的问候，本

是的，你可以。我修改了你的代码并用document.ready（）封装它。

$(document).ready(function () {
    window.mobilecheck = function () {            
        var x = document.createElement('link');
        x.rel = "stylesheet";
        x.href = "~/Styles/Default.css";            
        (function (a) {
