Question: In the project, the data format passed from the backend is like this. How do I get the value in BYMONTH? {Code...} Thinking: One way I thought of is to parse it into JSON: {Code...} Question: How should I process this data format?

var res = {};
str.split(';').map(function(v){
    var i = v.split('=');
    res[i[0]]=i[1];

console.log(res['BYMONTH']);

function getUrlParam(sUrl, sKey) {
    var result,Oparam = {};
    sUrl.replace(/[\;]?(\w+)=(\w+)/g,function($0,$1,$2){
       Oparam[$1]=$2;
    });
    sKey === void 0||sKey==='' ? result=Oparam : result=Oparam[sKey]||'';
    return result;
}
getUrlParam("INTERVAL=8;BYMONTH=9;BYMONTHDAY=17","BYMONTH")  //9

What I’m more curious about is why the backend doesn’t directly return json format? It has to be processed on the front end.
