我会用这个小而完整的库来处理js中的url:

https://github.com/Mikhus/jsurl

我是这么做的。使用我的editParams()函数，你可以添加，删除或更改任何参数，然后使用内置的replaceState()函数更新URL:

window.history.replaceState('object or string', 'Title', 'page.html' + editParams('enable', 'true'));


// background functions below:

// add/change/remove URL parameter
// use a value of false to remove parameter
// returns a url-style string
function editParams (key, value) {
  key = encodeURI(key);

  var params = getSearchParameters();

  if (Object.keys(params).length === 0) {
    if (value !== false)
      return '?' + key + '=' + encodeURI(value);
    else
      return '';
  }

  if (value !== false)
    params[key] = encodeURI(value);
  else
    delete params[key];

  if (Object.keys(params).length === 0)
    return '';

  return '?' + $.map(params, function (value, key) {
    return key + '=' + value;
  }).join('&');
}

// Get object/associative array of URL parameters
function getSearchParameters () {
  var prmstr = window.location.search.substr(1);
  return prmstr !== null && prmstr !== "" ? transformToAssocArray(prmstr) : {};
}

// convert parameters from url-style string to associative array
function transformToAssocArray (prmstr) {
  var params = {},
      prmarr = prmstr.split("&");

  for (var i = 0; i < prmarr.length; i++) {
    var tmparr = prmarr[i].split("=");
    params[tmparr[0]] = tmparr[1];
  }
  return params;
}

var MyApp = new Class();

MyApp.extend({
    utility: {
        queryStringHelper: function (url) {
            var originalUrl = url;
            var newUrl = url;
            var finalUrl;
            var insertParam = function (key, value) {
                key = escape(key);
                value = escape(value);

                //The previous post had the substr strat from 1 in stead of 0!!!
                var kvp = newUrl.substr(0).split('&');

                var i = kvp.length;
                var x;
                while (i--) {
                    x = kvp[i].split('=');

                    if (x[0] == key) {
                        x[1] = value;
                        kvp[i] = x.join('=');
                        break;
                    }
                }

                if (i < 0) {
                    kvp[kvp.length] = [key, value].join('=');
                }

                finalUrl = kvp.join('&');

                return finalUrl;
            };

            this.insertParameterToQueryString = insertParam;

            this.insertParams = function (keyValues) {
                for (var keyValue in keyValues[0]) {
                    var key = keyValue;
                    var value = keyValues[0][keyValue];
                    newUrl = insertParam(key, value);
                }
                return newUrl;
            };

            return this;
        }
    }
});

它处理这样的URL:

空 没有任何参数 已经有一些参数 有什么?在最后，但同时没有任何参数

它不处理这样的URL:

带有片段标识符(即散列，#) 如果URL已经有必要的查询参数(那么将会有重复)

适用于:

Chrome 32 + 火狐26 + 野生动物园7.1 +

function appendQueryParameter(url, name, value) {
    if (url.length === 0) {
        return;
    }

    let rawURL = url;

    // URL with `?` at the end and without query parameters
    // leads to incorrect result.
    if (rawURL.charAt(rawURL.length - 1) === "?") {
        rawURL = rawURL.slice(0, rawURL.length - 1);
    }

    const parsedURL = new URL(rawURL);
    let parameters = parsedURL.search;

    parameters += (parameters.length === 0) ? "?" : "&";
    parameters = (parameters + name + "=" + value);

    return (parsedURL.origin + parsedURL.pathname + parameters);
}

使用ES6模板字符串的版本。

适用于:

Chrome 41 + 火狐32 + 野生动物园9.1 +

function appendQueryParameter(url, name, value) {
    if (url.length === 0) {
        return;
    }

    let rawURL = url;

    // URL with `?` at the end and without query parameters
    // leads to incorrect result.
    if (rawURL.charAt(rawURL.length - 1) === "?") {
        rawURL = rawURL.slice(0, rawURL.length - 1);
    }

    const parsedURL = new URL(rawURL);
    let parameters = parsedURL.search;

    parameters += (parameters.length === 0) ? "?" : "&";
    parameters = `${parameters}${name}=${value}`;

    return `${parsedURL.origin}${parsedURL.pathname}${parameters}`;
}

这将在所有现代浏览器中工作。

function insertParam(key,value) {
      if (history.pushState) {
          var newurl = window.location.protocol + "//" + window.location.host + window.location.pathname + '?' +key+'='+value;
          window.history.pushState({path:newurl},'',newurl);
      }
    }

我们可以导入node中的内置URL模块，如下所示

const { URL } = require('url');

例子:

Terminal $ node
> const { URL } = require('url');
undefined
> let url = new URL('', 'http://localhost:1989/v3/orders');
undefined
> url.href
'http://localhost:1989/v3/orders'
> let fetchAll=true, timePeriod = 30, b2b=false;
undefined
> url.href
'http://localhost:1989/v3/orders'
>  url.searchParams.append('fetchAll', fetchAll);
undefined
>  url.searchParams.append('timePeriod', timePeriod);
undefined
>  url.searchParams.append('b2b', b2b);
undefined
> url.href
'http://localhost:1989/v3/orders?fetchAll=true&timePeriod=30&b2b=false'
> url.toString()
'http://localhost:1989/v3/orders?fetchAll=true&timePeriod=30&b2b=false'
