Plain Javascript Equivalent of jQuery.param()

Question

jQuery.param() takes an array of key-value pairs, and turns it into a string you can use as a query string in HTML requests. For example,

a = {
      userid:1,
         


        

Answer 1

@Amaynut's answer is awesome. But I do some simplify:

const obj = {
  userid: 1,
  gender: 'male'
}

const params = Object.keys(obj).map((k) => encodeURIComponent(k) + '=' + encodeURIComponent(obj[k])).join('&')

or maybe modulize it using es6 module:

util.js

export default {
  params (obj) {
    return Object.keys(obj).map((k) => encodeURIComponent(k) + '=' + encodeURIComponent(obj[k])).join('&')
  }
}

and use like this:

import util from './util'

const q = {
  userid: 1,
  gender: 'male'
}

const query = util.params(q)

console.log(query)
