快速的纯js小解决方案，不需要插件:

function replaceQueryParam(param, newval, search) {
    var regex = new RegExp("([?;&])" + param + "[^&;]*[;&]?");
    var query = search.replace(regex, "$1").replace(/&$/, '');

    return (query.length > 2 ? query + "&" : "?") + (newval ? param + "=" + newval : '');
}

这样叫它:

 window.location = '/mypage' + replaceQueryParam('rows', 55, window.location.search)

或者，如果你想保持在同一页上并替换多个参数:

 var str = window.location.search
 str = replaceQueryParam('rows', 55, str)
 str = replaceQueryParam('cols', 'no', str)
 window.location = window.location.pathname + str

Luke:要完全删除参数，为值传递false或null: replaceQueryParam('rows'， false, params)。因为0也是假的，所以指定'0'。

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('sorting', ModifiedTimeAsc));


// 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;
}

想想这个例子:

const myUrl = new URL("http://www.example.com?columns=5&rows=20");
myUrl.searchParams.set('rows', 10);
console.log(myUrl.href); // http://www.example.com?columns=5&rows=10
myUrl.searchParams.set('foo', 'bar'); // add new param
console.log(myUrl.href); // http://www.example.com?columns=5&rows=10&foo=bar

它会做和你要求的完全一样的事情。请注意URL必须有正确的格式。在你的例子中，你必须指定协议(http或https)

使用URLSearchParams检查，获取并设置参数值为URL

下面是获取当前URL并设置新参数并根据需要更新URL或重新加载页面的示例

var rows = 5; // value that you want to set
var url = new URL(window.location);
(url.searchParams.has('rows') ? url.searchParams.set('rows', rows) : url.searchParams.append('rows', rows));

url.search = url.searchParams;
url        = url.toString();

// if you want to append into URL without reloading the page
history.pushState({}, null, url);

// want to reload the window with a new param
window.location = url;

您可以使用我的这个库来完成这项工作:https://github.com/Mikhus/jsurl

var url = new Url('site.fwx?position=1&archiveid=5000&columns=5&rows=20&sorting=ModifiedTimeAsc');
url.query.rows = 10;
alert( url);

var url = new URL(window.location.href);
var search_params = url.searchParams;
search_params.set("param", value);
url.search = search_params.toString();
var new_url = url.pathname + url.search;
window.history.replaceState({}, '', new_url);
