您可以使用浏览器的本地URL API以一种相当简单的方式做到这一点，其中key和value分别是参数名和参数值。

const url = new URL(location.href);
url.searchParams.set(key, value);

history.pushState(null, '', url);

这将保留有关URL的所有内容，只更改或添加一个查询参数。如果您不希望它创建一个新的浏览器历史记录条目，也可以使用replaceState而不是pushState。

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))

我从这里得出的结论(与“使用严格”相容;并不真正使用jQuery):

function decodeURIParams(query) {
  if (query == null)
    query = window.location.search;
  if (query[0] == '?')
    query = query.substring(1);

  var params = query.split('&');
  var result = {};
  for (var i = 0; i < params.length; i++) {
    var param = params[i];
    var pos = param.indexOf('=');
    if (pos >= 0) {
        var key = decodeURIComponent(param.substring(0, pos));
        var val = decodeURIComponent(param.substring(pos + 1));
        result[key] = val;
    } else {
        var key = decodeURIComponent(param);
        result[key] = true;
    }
  }
  return result;
}

function encodeURIParams(params, addQuestionMark) {
  var pairs = [];
  for (var key in params) if (params.hasOwnProperty(key)) {
    var value = params[key];
    if (value != null) /* matches null and undefined */ {
      pairs.push(encodeURIComponent(key) + '=' + encodeURIComponent(value))
    }
  }
  if (pairs.length == 0)
    return '';
  return (addQuestionMark ? '?' : '') + pairs.join('&');
}

//// alternative to $.extend if not using jQuery:
// function mergeObjects(destination, source) {
//   for (var key in source) if (source.hasOwnProperty(key)) {
//     destination[key] = source[key];
//   }
//   return destination;
// }

function navigateWithURIParams(newParams) {
  window.location.search = encodeURIParams($.extend(decodeURIParams(), newParams), true);
}

使用示例:

// add/update parameters
navigateWithURIParams({ foo: 'bar', boz: 42 });

// remove parameter
navigateWithURIParams({ foo: null });

// submit the given form by adding/replacing URI parameters (with jQuery)
$('.filter-form').submit(function(e) {
  e.preventDefault();
  navigateWithURIParams(decodeURIParams($(this).serialize()));
});

给出Gal和tradyblix建议的修改window.location.search的代码示例:

var qs = window.location.search || "?";
var param = key + "=" + value; // remember to URI encode your parameters
if (qs.length > 1) {
    // more than just the question mark, so append with ampersand
    qs = qs + "&";
}
qs = qs + param;
window.location.search = qs;

查找特定查询字符串并替换其值*的Java脚本代码

('input.letter').click(function () {
                //0- prepare values
                var qsTargeted = 'letter=' + this.value; //"letter=A";
                var windowUrl = '';
                var qskey = qsTargeted.split('=')[0];
                var qsvalue = qsTargeted.split('=')[1];
                //1- get row url
                var originalURL = window.location.href;
                //2- get query string part, and url
                if (originalURL.split('?').length > 1) //qs is exists
                {
                    windowUrl = originalURL.split('?')[0];
                    var qs = originalURL.split('?')[1];
                    //3- get list of query strings
                    var qsArray = qs.split('&');
                    var flag = false;
                    //4- try to find query string key
                    for (var i = 0; i < qsArray.length; i++) {
                        if (qsArray[i].split('=').length > 0) {
                            if (qskey == qsArray[i].split('=')[0]) {
                                //exists key
                                qsArray[i] = qskey + '=' + qsvalue;
                                flag = true;
                                break;
                            }
                        }
                    }
                    if (!flag)//   //5- if exists modify,else add
                    {
                        qsArray.push(qsTargeted);
                    }
                    var finalQs = qsArray.join('&');
                    //6- prepare final url
                    window.location = windowUrl + '?' + finalQs;
                }
                else {
                    //6- prepare final url
                    //add query string
                    window.location = originalURL + '?' + qsTargeted;
                }
            })
        });

如果它没有设置或想要更新一个新值，您可以使用:

window.location.search = 'param=value'; // or param=new_value

这是用简单Javascript写的。

EDIT

你可能想尝试使用jquery查询对象插件

窗口.位置.搜索 = jQuery.query.set（“param”， 5）;
