方法一：利用 splice 分割 + 循环依次取出

方法一：
function queryURLparams(url) {let obj = {}if (url.indexOf('?') < 0) return objlet arr = url.split('?')url = arr[1]let array = url.split('&')for (let i = 0; i < array.length; i++) {let arr2 = array[i]let arr3 = arr2.split('=')obj[arr3[0]] = arr3[1]}return obj}
方法二：function getURL(url){let str = url.split("?")[1];let str1 = str.split("&");let obj = {};for(let i = 0; i<str1.length; i++){let str2 = str1[i].split("=");let key = str2[0];let value = str2[1];obj[key] = value;}return obj;}console.log(getURL(url))

方法二: 正则 + arguments

function queryURLparamsRegEs5(url) {let obj = {}let reg = /([^?=&]+)=([^?=&]+)/gurl.replace(reg, function() {obj[arguments[1]] = arguments[2]})return obj
}
