Solution to jquery getting url parameter garbled:

Method 1 : Regular analysis method

The code is as follows:

function getQueryString(name) {
var reg = new RegExp("(^|&)" + name + "=([^&]*)(&|$)", "i");
var r = window.location.search.substr(1).match(reg);
if (r != null) return unescape(r[2]); return null;
}

Called like this:

The code is as follows:

alert(GetQueryString("参数名1"));
alert(GetQueryString("参数名2"));
alert(GetQueryString("参数名3"));

Method 2:

The code is as follows:

<span style="font-size: 16px;"><Script language="javascript">
function GetRequest() {
var url = location.search; //获取url中"?"符后的字串
var theRequest = new Object();
if (url.indexOf("?") != -1) {
var str = url.substr(1);
strs = str.split("&");
for(var i = 0; i < strs.length; i ++) {
theRequest[strs[i].split("=")[0]]=unescape(strs[i].split("=")[1]);
}
}
return theRequest;
}
</Script></span>

1. Call like this:

The code is as follows:

<Script language="javascript">
var Request = new Object();
Request = GetRequest();
var 参数1,参数2,参数3,参数N;
参数1 = Request[&#39;参数1&#39;];
参数2 = Request[&#39;参数2&#39;];
参数3 = Request[&#39;参数3&#39;];
参数N = Request[&#39;参数N&#39;];
</Script>

If the parameters contain Chinese characters, pay attention to the encoding and decoding ：

The code is as follows:

<span style="font-size:18px;">1.传参页面
Javascript代码：<script type=”text/javascript”>
function send(){
var url = "test01.html";
var userName = $("#userName").html();
window.open(encodeURI(url + "?userName=" + userName)); }
</script>

2. Receive parameter page: test02.html

<script>
var urlinfo = window.location.href;//获取url
var userName = urlinfo.split(“?”)[1].split(“=”)[1];//拆分url得到”=”后面的参数
$(“#userName”).html(decodeURI(userName));
</script></span>
