How to get URL parameter’s value in javascript?

Overview
In this post, will explain a problem which we often struggle with. How do we get query parameter values from a URL in Javascript?

There isn’t a simple straight forward request object which could help you. However, there are many ways (custom solutions) which you could try. Here is one of the custom solution to get the value of the parameter

Sample Code

// To get array of parameters

function getAllParameters(url) {

        var params = {};

        var parts = url.replace(/[?&]+([^=&]+)=([^&]*)/gi,  function(m,key,value) {

            params[key] = value;

        });

        return params;

    };

//Get the value of the parameter

  function getParamValue(param, url){

        var paramValue = '';

        if(url.indexOf(param) > -1){

            paramValue = getAllParameters(url)[param];

        }

        return paramValue;

 }

#INPUT

var sampleURL = 'https://www.example.com?productCode=938939&productName=fcybers';

console.log(getParamValue('productCode' , sampleURL))

console.log(getParamValue('productName' , sampleURL))

#OUTPUT

938939
