如果你想一次设置多个参数:

function updateQueryStringParameters(uri, params) {
    for(key in params){
      var value = params[key],
          re = new RegExp("([?&])" + key + "=.*?(&|$)", "i"),
          separator = uri.indexOf('?') !== -1 ? "&" : "?";
      if (uri.match(re)) {
        uri = uri.replace(re, '$1' + key + "=" + value + '$2');
      }
      else {
        uri = uri + separator + key + "=" + value;
      }
    }
    return uri;
}

与@amateur的函数相同

如果jslint给出了一个错误，在for循环之后添加这个

if(params.hasOwnProperty(key))

我写了下面的函数来实现我想要实现的:

function updateQueryStringParameter(uri, key, value) {
  var re = new RegExp("([?&])" + key + "=.*?(&|$)", "i");
  var separator = uri.indexOf('?') !== -1 ? "&" : "?";
  if (uri.match(re)) {
    return uri.replace(re, '$1' + key + "=" + value + '$2');
  }
  else {
    return uri + separator + key + "=" + value;
  }
}

下面是我的库:https://github.com/Mikhus/jsurl

var u = new Url;
u.query.param='value'; // adds or replaces the param
alert(u)

感谢现代javascript, node.js和浏览器的支持，我们可以摆脱第三方库的漩涡(jquery, query-string等)和DRY自己。

下面是javascript(node.js)和typescript版本的函数，用于添加或更新给定url的查询参数:

Javascript

const getUriWithParam = (baseUrl, params) => { const Url = new URL(baseUrl); const urlParams = new URLSearchParams(Url.search); for (const key in params) { if (params[key] !== undefined) { urlParams.set(key, params[key]); } } Url.search = urlParams.toString(); return Url.toString(); }; console.info('expected: https://example.com/?foo=bar'); console.log(getUriWithParam("https://example.com", {foo: "bar"})); console.info('expected: https://example.com/slug?foo=bar#hash'); console.log(getUriWithParam("https://example.com/slug#hash", {foo: "bar"})); console.info('expected: https://example.com/?bar=baz&foo=bar'); console.log(getUriWithParam("https://example.com?bar=baz", {foo: "bar"})); console.info('expected: https://example.com/?foo=baz&bar=baz'); console.log(getUriWithParam("https://example.com?foo=bar&bar=baz", {foo: "baz"}));

打印稿

const getUriWithParam = (
  baseUrl: string,
  params: Record<string, any>
): string => {
  const Url = new URL(baseUrl);
  const urlParams: URLSearchParams = new URLSearchParams(Url.search);
  for (const key in params) {
    if (params[key] !== undefined) {
      urlParams.set(key, params[key]);
    }
  }
  Url.search = urlParams.toString();
  return Url.toString();
};

对于React Native

URL在React Native中没有实现。所以你必须事先安装react-native-url-polyfill。

对于对象参数

请看这个答案中的第二个解决方案

URLSearchParams是如此简单，所有现代浏览器(caniuse)都支持。

let p = new URLSearchParams(); p.set(“foo”、“酒吧”); p.set(“name”，“Jack & Jill?”); console.log (" http://example.com/? "+ p.toString ());

如果你想修改现有的URL，像这样构造对象:new URLSearchParams(window.location.search)并将字符串赋值给window.location.search。

这个答案只是ellemayo的答案的一个小调整。它将自动更新URL，而不只是返回更新后的字符串。

function _updateQueryString(key, value, url) {
    if (!url) url = window.location.href;

    let updated = ''
    var re = new RegExp("([?&])" + key + "=.*?(&|#|$)(.*)", "gi"),
        hash;

    if (re.test(url)) {
        if (typeof value !== 'undefined' && value !== null) {
            updated = url.replace(re, '$1' + key + "=" + value + '$2$3');
        } 
        else {
            hash = url.split('#');
            url = hash[0].replace(re, '$1$3').replace(/(&|\?)$/, '');
            if (typeof hash[1] !== 'undefined' && hash[1] !== null) {
                url += '#' + hash[1];
            }
            updated = url;
        }
    }
    else {
        if (typeof value !== 'undefined' && value !== null) {
            var separator = url.indexOf('?') !== -1 ? '&' : '?';
            hash = url.split('#');
            url = hash[0] + separator + key + '=' + value;
            if (typeof hash[1] !== 'undefined' && hash[1] !== null) {
                url += '#' + hash[1];
            }
            updated = url;
        }
        else {
            updated = url;
        }
    }

    window.history.replaceState({ path: updated }, '', updated);
}
