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;

使用此函数可以添加、删除和修改URL中的查询字符串参数

/**
@param String url
@param object param {key: value} query parameter
*/
function modifyURLQuery(url, param){
    var value = {};

    var query = String(url).split('?');

    if (query[1]) {
        var part = query[1].split('&');

        for (i = 0; i < part.length; i++) {
            var data = part[i].split('=');

            if (data[0] && data[1]) {
                value[data[0]] = data[1];
            }
        }
    }

    value = $.extend(value, param);

    // Remove empty value
    for (i in value){
        if(!value[i]){
            delete value[i];
        }
    }

    // Return url with modified parameter
    if(value){
        return query[0] + '?' + $.param(value);
    } else {
        return query[0];
    }
}

添加新的和修改现有参数的url

var new_url = modifyURLQuery("http://google.com?foo=34", {foo: 50, bar: 45});
// Result: http://google.com?foo=50&bar=45

删除现有的

var new_url = modifyURLQuery("http://google.com?foo=50&bar=45", {bar: null});
// Result: http://google.com?foo=50

我想要的是:

使用浏览器的本地URL API 可以添加、更新、获取或删除吗 期望在散列之后的查询字符串，例如对于单页应用程序

function queryParam(options = {}) { var defaults = { method: 'set', url: window.location.href, key: undefined, value: undefined, } for (var prop in defaults) { options[prop] = typeof options[prop] !== 'undefined' ? options[prop] : defaults[prop] } const existing = (options.url.lastIndexOf('?') > options.url.lastIndexOf('#')) ? options.url.substr(options.url.lastIndexOf('?') + 1) : '' const query = new URLSearchParams(existing) if (options.method === 'set') { query.set(options.key, options.value) return `${options.url.replace(`?${existing}`, '')}?${query.toString()}` } else if (options.method === 'get') { const val = query.get(options.key) let result = val === null ? val : val.toString() return result } else if (options.method === 'delete') { query.delete(options.key) let result = `${options.url.replace(`?${existing}`, '')}?${query.toString()}` const lastChar = result.charAt(result.length - 1) if (lastChar === '?') { result = `${options.url.replace(`?${existing}`, '')}` } return result } } // Usage: let url = 'https://example.com/sandbox/#page/' url = queryParam({ url, method: 'set', key: 'my-first-param', value: 'me' }) console.log(url) url = queryParam({ url, method: 'set', key: 'my-second-param', value: 'you' }) console.log(url) url = queryParam({ url, method: 'set', key: 'my-second-param', value: 'whomever' }) console.log(url) url = queryParam({ url, method: 'delete', key: 'my-first-param' }) console.log(url) const mySecondParam = queryParam({ url, method: 'get', key: 'my-second-param', }) console.log(mySecondParam) url = queryParam({ url, method: 'delete', key: 'my-second-param' }) console.log(url)

下面是我的方法:location.params()函数(如下所示)可以用作getter或setter。例子:

假设URL是http://example.com/?foo=bar&baz#some-hash，

Location.params()将返回一个包含所有查询参数的对象:{foo: 'bar'， baz: true}。 Location.params ('foo')将返回'bar'。 的位置。params({foo: undefined, hello: 'world'， test: true})会将URL更改为http://example.com/?baz&hello=world&test#some-hash。

下面是params()函数，它可以被选择性地分配给窗口。位置的对象。

location.params = function(params) {
  var obj = {}, i, parts, len, key, value;

  if (typeof params === 'string') {
    value = location.search.match(new RegExp('[?&]' + params + '=?([^&]*)[&#$]?'));
    return value ? value[1] : undefined;
  }

  var _params = location.search.substr(1).split('&');

  for (i = 0, len = _params.length; i < len; i++) {
    parts = _params[i].split('=');
    if (! parts[0]) {continue;}
    obj[parts[0]] = parts[1] || true;
  }

  if (typeof params !== 'object') {return obj;}

  for (key in params) {
    value = params[key];
    if (typeof value === 'undefined') {
      delete obj[key];
    } else {
      obj[key] = value;
    }
  }

  parts = [];
  for (key in obj) {
    parts.push(key + (obj[key] === true ? '' : '=' + obj[key]));
  }

  location.search = parts.join('&');
};

这是一个简短的版本

使用或不使用给定参数查询 使用多个参数值查询 包含散列的查询

代码:

var setQueryParameter = function(uri, key, value) {
  var re = new RegExp("([?&])("+ key + "=)[^&#]*", "g");
  if (uri.match(re)) 
    return uri.replace(re, '$1$2' + value);

  // need to add parameter to URI
  var paramString = (uri.indexOf('?') < 0 ? "?" : "&") + key + "=" + value;
  var hashIndex = uri.indexOf('#');
  if (hashIndex < 0)
    return uri + paramString;
  else
    return uri.substring(0, hashIndex) + paramString + uri.substring(hashIndex);
}

正则表达式描述可以在这里找到。

注意:这个解决方案是基于@amateur的答案，但是有很多改进。
