Convert URL to json

Question

I can't seem to find an answer to this question.. How can I convert a URL parameters string to JSON in javascript? I mean to ask if there is an in-built function like this or a one-liner that could do the job?

Example:

some=params&over=here => {"some":"params","over":"here"}

Answer 1

You can create a method which will return JSON object

var params = getUrlVars('some=params&over=here');
console.log(params);

function getUrlVars(url) {
    var hash;
    var myJson = {};
    var hashes = url.slice(url.indexOf('?') + 1).split('&');
    for (var i = 0; i < hashes.length; i++) {
        hash = hashes[i].split('=');
        myJson[hash[0]] = hash[1];
        // If you want to get in native datatypes
        // myJson[hash[0]] = JSON.parse(hash[1]); 
    }
    return myJson;
}

Try this :

var str = 'some1=param&some2=param2';

JSON.parse('{"' + decodeURI(str).replace(/"/g, '\\"').replace(/&/g, '","').replace(/=/g,'":"').replace(/\s/g,'') + '"}')

// {some1: "param1", some2: "param2"}
