let ref;
if (type === 'js') { //外部JS
ref = document.createElement('script')
ref.setAttribute('type', 'text/javascript')
ref.setAttribute('src', name)
} else if (type === 'css') { //外部css
ref = document.createElement('link')
ref.setAttribute('rel','stylesheet')
ref.setAttribute('type','text/css')
ref.setAttribute('href',name)
}else if(type === 'style') { //style
ref = document.createElement('style')
ref.innerHTML = name
}
if (typeof ref !== 'undefined') {
document.getElementsByTagName('head')[0].appendChild(ref)
ref.onload = function () { //加載執(zhí)行完畢
typeof fn === 'function' && fn()
}
}
}
獲取URL參數(shù)
const getUrlParam = function(name) {
let req = new RegExp('(^|&?)' + name + '=([^&]*)(&|$)', 'i')

if(r !== null) {
return decodeURI(r[2])
