Question

I need convert json object to url form like: “parameter=12&asd=1”

I done with this:

        var data = {
            'action':'actualiza_resultado',
            'postID': 1,
            'gl': 2,
            'gl2' : 3
        };

        var string_=JSON.stringify(data);

        string_=string_.replace(/{/g, "");
        string_=string_.replace(/}/g, "");
        string_=string_.replace(/:/g, "=")
        string_=string_.replace(/,/g, "&");
        string_=string_.replace(/"/g, "");

But i wonder if there any function in javascript or in JSON object to do this?

Use the URLSearchParams interface, which is built into browsers and Node.js starting with version 10, released in 2018.

const myParams = {'foo': 'hi there', 'bar': '???'};

const u = new URLSearchParams(myParams).toString();

console.log(u);

Old answer: jQuery provides param that does exactly that. If you don’t use jquery, take at look at the source.

Basically, it goes like this:

url = Object.keys(data).map(function(k) {
    return encodeURIComponent(k) + '=' + encodeURIComponent(data[k])
}).join('&')
