打开github
原因1：如果你是想直接使用git网上的文件的话，你需要找到git cdn上的该js文件链接地址，放到script的src标签里即可。原因2：如果是想动态加载js，那可能的原因是js还未加载完全就执行导致出错。
若是原因2，可使用以下代码：
var ele = document.createElement('script'),
_head = document.getElementsByTagName('head')[0]
ele.type='text/javascript'
ele.src = "forGaofei这个文件的路径地址"
_head.appendChild(ele)
if (ele.readyState){ //IE
ele.onreadystatechange = function(){
if (ele.readyState == "loaded" || ele.readyState == "complete"){
ele.onreadystatechange = null
doSomething()
}
}
} else { //Firefox, Safari, Chrome, Opera
ele.onload = function(){
doSomething()
}
}
function doSomething(){
//需要此文件才能做的事情写在这里调用
}
