js实现获取url问号后参数，第一步封装方法获取?后所有字符，并根据&=符号获取单个或多个参数及参数值
getParams() {
var url = location.search;
var params = new Object();
if (url.indexOf("?") != -1) {
const str = url.substr(1);
const strs = str.split("&");
for (var i = 0; i < strs.length; i++) {
params[strs[i].split("=")[0]] = unescape(strs[i].split("=")[1]);
}
}
return params;
}方法写好后直接调用方法获取url。其中 urlParams['参数名']，如果参数名写错会获取不到此参数值。例：http:172.17.10.0:8080?id=123&name=张三，使用：urlParams['id']，urlParams['name']
console.log(window.location.search)
var urlParams = new Object();
urlParams = this.getParams();
this.id = urlParams['id']; //要获取的参数名
this.name = urlParams['name']; //要获取的参数名
console.log(this.id, this.name)
