我一直试图阻止下面提到的脚本加载到移动设备上，但不能。 任何人都可以编辑脚本或代码并使其在移动设备上无法加载吗？

我不知道这是否是首选方式。但这就是我所使用的：
if (window.innerWidth >= 800 && window.innerHeight >= 600) {
//your function call
}
答案 2 :(得分：0)
使用CSS3媒体查询API，称为window.matchMedia。
例如：
var mediaQuery = window.matchMedia( "(max-width: 768px)" );
if (mediaQuery.matches) {
// your code on mobile or small screen devices
} else {
// your code on everything else
}
工作代码段（检查内联并展开代码段）：
var mediaQuery = window.matchMedia( "(max-width: 768px)" );
if (mediaQuery.matches) {
console.log('small screen code runs here');
} else {
console.log('big screen code runs here');
}
