Jquery gets the parameters in the URL and solves the problem of Chinese garbled parameters.

Method 1:

//获取url中的参数
function getUrlParamCN(name) {
var reg = new RegExp("(^|&)" + name + "=([^&]*)(&|$)"); //构造一个含有目标参数的正则表达式对象
var r = decodeURI(window.location.search).substr(1).match(reg); //匹配目标参数
if (r != null) return unescape(r[2]); return null; //返回参数值
}

Method 2:

1. Pass parameter page.html

<script type="text/javascript">
    var name = &#39;abc&#39;;  //字符串英文
    var num = 998;   //数字
    var cla= &#39;电脑&#39;;  //中文
    var _t = encodeURI(encodeURI(cla));  
    //中文需要进行两次encodeURI转码( encodeURI:把URI字符串采用UTF-8编码格式转化成escape格式的字符串。)
    window.location.href = "../aa.html?name=" + name(字符串) + "&num=num (数字)" + "&cla=_t (中文)";
 
</script>

2. Receive parameter page.html

(Final page address: ../aa.html?name=abc&num=998&cla=%E7%94%B5%E8%84%91)

<script type="text/javascript">
    //获取地址参数
    var _name = getQueryString("name");
    var _num=getQueryString("num");
    var _t = getQueryString("cla"); //此为中文参数，需转码
    var title = decodeURI(_t); //只需要转一次码  
 
    console.log(title);//此处打印出来是中文。
 
 
 
    function getQueryString(name) {  
        //正则表达式，获取地址中的参数
        var reg = new RegExp("(^|&)" + name + "=([^&]*)(&|$)", "i");  
        var r = window.location.search.substr(1).match(reg);  
 
        if (r != null) return unescape(r[2]); return null; 
 
    }
 
</script>
