This article mainly introduces the conversion of URL into JSON format. It has certain reference value. Now I share it with you. Friends in need can refer to it.

There are many online methods and various tricks. Damn it, here is a more normal idea.
Mainly use split to continuously split the obtained string, and finally obtain the required format.
The code is as follows

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>将url转化为json数据</title>
</head>
<script>
    function queryString(url){
        let arr=[]; //存储参数的数组
        let res={}; //存储最终JSON结果对象
        arr=url.split("?")[1].split("&"); //arr=["a=1", "b=2", "c=test", "d"]

        for(let i=0,len=arr.length;i<len;i++){
            //如果有等号，则执行赋值操作
            if(arr[i].indexOf("=")!=-1){
                let str=arr[i].split("=");
                //str=[a,1];
                res[str[0]]=str[1];
            }else{//没有等号，则赋予空值
                res[arr[i]]="";
            }
        }
        res=JSON.stringify(res);//转化为JSON字符串
        return res; //{"a": "1", "b": "2", "c": "test", "d": ""}
    }
    console.log(queryString(&#39;www.baidu.com?a=1&b=2&c=test&d&#39;));
</script>
<body>  
</body>
</html>
