Change all values in string of format "key=value&..."

Question

I have a string:

var data = 'key1=value1&key2=value2&...';

String has a huge number of keys-values combinations. I need to change all values, by some rule - encodeURIComponent it. I need to do that only relatively to values (and maybe keys), but now for the whole string.

Is there complete algorithm to do that?

you probably want to use URLSearchParams - https://developer.mozilla.org/en-US/docs/Web/API/URLSearchParams — Derek Pollard, Sep 16 '20 at 17:58

You can use this code to create an object out of the data:

var data="key1=value1&key2=value2&key3=value3";
var obj=Object.fromEntries(
    data.split("&").reduce((acc,cv)=>{
    acc.push(cv.split("="));
    return acc;
  },[])
);
console.log(obj);

.as-console-wrapper { max-height: 100% !important; top: 0; }

Then you can access whichever key you want and get it's value, say:

obj["key2"]

You might need to unescape values.
