new URL(location.href) doesn't work in IE

Question

I am facing to problem with method new URL(\'address\') in IE.

I have this code:

var href =  location.href;
var hrefParams = new URL(href);
var api =         


        

Answer 1

IE does not support URL. You will have to add a polyfill for it.

Answer 2

Add polyfill cdn script

<script src="https://cdn.polyfill.io/v2/polyfill.min.js"></script>

Answer 3

Another solution I've been using if anyone is interested

function getParameterByName(name) {
  name = name.replace(/[\[]/, "\\[").replace(/[\]]/, "\\]");
  var regex = new RegExp("[\\?&]" + name + "=([^&#]*)"),
      results = regex.exec(location.search);
  return results === null ? "" : decodeURIComponent(results[1].replace(/\+/g, " "));
}

getParameterByName('api');

Answer 4

Pure Javascript solution, so you can run it in IE as well without bothering with polyfills:

   function getUrlVars() {
        var vars = {};
        var parts = window.location.href.replace(/[?&]+([^=&]+)=([^&]*)/gi, function(m,key,value) {
            vars[key] = value;
        });
        return vars;
    }

Answer 5

This method is not supported by IE

See https://developer.mozilla.org/en-US/docs/Web/API/URL#AutoCompatibilityTable

you should use a lib like jquery deparam or retrieve the parameters with String.split() method or use this function that I made:

function decodeUriComponentWithSpace (component) {
    return decodeURIComponent(component.replace(/\+/g, '%20'))
  }

  // type : 'hash', 'search' or 'both'
  function getLocationParameters (location, type) {
    if (type !== 'hash' && type !== 'search' && type !== 'both') {
      throw 'getLocationParameters expect argument 2 "type" to be "hash", "search" or "both"'
    }

    let searchString = typeof location.search === 'undefined' ? '' : location.search.substr(1)
    let hashString = typeof location.hash === 'undefined' ? '' : location.hash.substr(1)
    let queries = []
    if (type === 'search' || type === 'both') {
      queries = queries.concat(searchString.split('&'))
    }
    if (type === 'hash' || type === 'both') {
      queries = queries.concat(hashString.split('&'))
    }

    let params = {}
    let pair

    for (let i = 0; i < queries.length; i++) {
      if (queries[i] !== '') {
        pair = queries[i].split('=')
        params[this.decodeUriComponentWithSpace(pair[0])] = this.decodeUriComponentWithSpace(pair[1])
      }
    }
    return params
}

   // TEST: 
window.location.hash = 'test=a&test2=b'
console.log(getLocationParameters(window.location, 'both'))

For the purposes of my project, I've created this script, which I think also could work for you or someone else who has a problem with IE11 and the lack of support for the URL method.

        /* Polyfill URL method IE 11 */

        // ES5

        if (typeof window.URL !== 'function') {
            window.URL = function (url) {
                var protocol = url.split('//')[0],
                    comps = url.split('#')[0].replace(/^(https\:\/\/|http\:\/\/)|(\/)$/g, '').split('/'),
                    host = comps[0],
                    search = comps[comps.length - 1].split('?')[1],
                    tmp = host.split(':'),
                    port = tmp[1],
                    hostname = tmp[0];

                search = typeof search !== 'undefined' ? '?' + search : '';

                var params = search
                    .slice(1)
                    .split('&')
                    .map(function (p) { return p.split('='); })
                    .reduce(function (p, c) {
                        var parts = c.split('=', 2).map(function (param) { return decodeURIComponent(param); });
                        if (parts.length == 0 || parts[0] != param) return (p instanceof Array) && !asArray ? null : p;
                        return asArray ? p.concat(parts.concat(true)[1]) : parts.concat(true)[1];
                    }, []);

                return {
                    hash: url.indexOf('#') > -1 ? url.substring(url.indexOf('#')) : '',
                    protocol: protocol,
                    host: host,
                    hostname: hostname,
                    href: url,
                    pathname: '/' + comps.splice(1).map(function (o) { return /\?/.test(o) ? o.split('?')[0] : o; }).join('/'),
                    search: search,
                    origin: protocol + '//' + host,
                    port: typeof port !== 'undefined' ? port : '',
                    searchParams: {
                        get: function(p) {
                            return p in params? params[p] : ''
                        },
                        getAll: function(){ return params; }
                    }
                };
            }
        }

        // ES6, in case of using Babel in a project

        if( typeof window.URL !== 'function' ){
            window.URL = function(url){
                let protocol = url.split('//')[0],
                    comps = url.split('#')[0].replace(/^(https\:\/\/|http\:\/\/)|(\/)$/g, '').split('/'),
                    host = comps[0],
                    search = comps[comps.length - 1].split('?')[1],
                    tmp = host.split(':'), 
                    port = tmp[1], 
                    hostname = tmp[0];

                search = typeof search !== 'undefined'? '?' + search : '';

                const params = search
                                    .slice(1)
                                    .split('&')
                                    .map(p => p.split('='))
                                    .reduce((obj, pair) => {
                                        const [key, value] = pair.map(decodeURIComponent);
                                        return ({ ...obj, [key]: value })
                                    }, {});

                return {
                    hash: url.indexOf('#') > -1? url.substring(url.indexOf('#')) : '',
                    protocol,
                    host,
                    hostname,
                    href: url,
                    pathname: '/' + comps.splice(1).map(function(o){ return /\?/.test(o)? o.split('?')[0] : o; }).join('/'),
                    search,
                    origin: protocol + '//' + host,
                    port: typeof port !== 'undefined'? port : '',
                    searchParams: {
                        get: p => p in params? params[p] : '',
                        getAll: () => params
                    }
                };
            }
        }
        /* Polyfill IE 11 end */

        new URL('http://localhost:8080/?a=1&b=3&c=z#123').searchParams.get('c'); // this will return "z"

But if it doesn't work for you, you could take I think full suported and polifilled function from this package here on the url:
