我有这个网址:

site.fwx?position=1&archiveid=5000&columns=5&rows=20&sorting=ModifiedTimeAsc

我需要的是能够将'rows' url参数值更改为我指定的值,比如说10。如果'rows'不存在,我需要将它添加到url的末尾并添加我已经指定的值 (10)。

我已经扩展了 Sujoy 的代码以组成一个函数。

/**
 * http://stackoverflow.com/a/10997390/11236
 */
function updateURLParameter(url, param, paramVal){
    var newAdditionalURL = "";
    var tempArray = url.split("?");
    var baseURL = tempArray[0];
    var additionalURL = tempArray[1];
    var temp = "";
    if (additionalURL) {
        tempArray = additionalURL.split("&");
        for (var i=0; i<tempArray.length; i++){
            if(tempArray[i].split('=')[0] != param){
                newAdditionalURL += temp + tempArray[i];
                temp = "&";
            }
        }
    }

    var rows_txt = temp + "" + param + "=" + paramVal;
    return baseURL + "?" + newAdditionalURL + rows_txt;
}

函数调用:

var newURL = updateURLParameter(window.location.href, 'locId', 'newLoc');
newURL = updateURLParameter(newURL, 'resId', 'newResId');

window.history.replaceState('', '', updateURLParameter(window.location.href, "param", "value"));

更新的版本也处理 URL 上的锚点。

function updateURLParameter(url, param, paramVal)
{
    var TheAnchor = null;
    var newAdditionalURL = "";
    var tempArray = url.split("?");
    var baseURL = tempArray[0];
    var additionalURL = tempArray[1];
    var temp = "";

    if (additionalURL) 
    {
        var tmpAnchor = additionalURL.split("#");
        var TheParams = tmpAnchor[0];
            TheAnchor = tmpAnchor[1];
        if(TheAnchor)
            additionalURL = TheParams;

        tempArray = additionalURL.split("&");

        for (var i=0; i<tempArray.length; i++)
        {
            if(tempArray[i].split('=')[0] != param)
            {
                newAdditionalURL += temp + tempArray[i];
                temp = "&";
            }
        }        
    }
    else
    {
        var tmpAnchor = baseURL.split("#");
        var TheParams = tmpAnchor[0];
            TheAnchor  = tmpAnchor[1];

        if(TheParams)
            baseURL = TheParams;
    }

    if(TheAnchor)
        paramVal += "#" + TheAnchor;

    var rows_txt = temp + "" + param + "=" + paramVal;
    return baseURL + "?" + newAdditionalURL + rows_txt;
}

我想你想要查询插件

例如:

window.location.search = jQuery.query.set("rows", 10);

无论行的当前状态如何,这都将起作用。

4年后,在学到了很多东西之后回答我自己的问题。特别是你不应该对所有事情都使用 jQuery。我创建了一个可以解析/字符串化查询字符串的简单模块。这使得修改查询字符串变得容易。

您可以按如下方式使用查询字符串:

// parse the query string into an object
var q = queryString.parse(location.search);
// set the `row` property
q.rows = 10;
// convert the object to a query string
// and overwrite the existing query string
location.search = queryString.stringify(q);

纯 js 中的快速小解决方案,无需插件:

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 : '');
}

像这样称呼它:

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

或者,如果您想留在同一页面上并替换多个参数:

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

编辑,谢谢卢克:要完全删除参数,请传递falsenull作为值:replaceQueryParam('rows', false, params)。既然0 也是假的,请指定'0'

Ben Alman 在这里有一个很好的 jquery 查询字符串/url 插件,可以让您轻松地操作查询字符串。

按照要求 -

在这里转到他的测试页面

在 firebug 中在控制台中输入以下内容

jQuery.param.querystring(window.location.href, 'a=3&newValue=100');

它将返回以下修改后的 url 字符串

http://benalman.com/code/test/js-jquery-url-querystring.html?a=3&b=Y&c=Z&newValue=100#n=1&o=2&p=3

请注意 a 的 a 查询字符串值已从 X 更改为 3,并且添加了新值。

然后,您可以根据需要使用新的 url 字符串,例如使用 document.location = newUrl 或更改锚链接等

一种现代方法是使用基于原生标准的URLSearchParams。所有主流浏览器都支持它,除了 IE,它们是可用的 polyfills

const paramsString = "site.fwx?position=1&archiveid=5000&columns=5&rows=20&sorting=ModifiedTimeAsc"
const searchParams = new URLSearchParams(paramsString);
searchParams.set('rows', 10);
console.log(searchParams.toString()); // return modified string.

你也可以通过普通的JS来做到这一点

var newAdditionalURL = "";
var tempArray = url.split("?");
var baseURL = tempArray[0];
var aditionalURL = tempArray[1]; 
var temp = "";
if(aditionalURL)
{
var tempArray = aditionalURL.split("&");
for ( var i in tempArray ){
    if(tempArray[i].indexOf("rows") == -1){
            newAdditionalURL += temp+tempArray[i];
                temp = "&";

使用URLSearchParams,并将参数值check放入 getsetURL

这是获取当前 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;

字符串操作的可行替代方法是设置一个 htmlform并仅修改rows元素的值吗?

所以,html就像这样

<form id='myForm' target='site.fwx'>
    <input type='hidden' name='position' value='1'/>
    <input type='hidden' name='archiveid' value='5000'/>
    <input type='hidden' name='columns' value='5'/>
    <input type='hidden' name='rows' value='20'/>
    <input type='hidden' name='sorting' value='ModifiedTimeAsc'/>
</form>

用下面的 JavaScript 提交表单

var myForm = document.getElementById('myForm');
myForm.rows.value = yourNewValue;
myForm.submit();

可能不适合所有情况,但可能比解析 URL 字符串更好。

2020 解决方案:设置变量或删除 iti 如果您将null或传递undefined给值。

var setSearchParam = function(key, value) {
    if (!window.history.pushState) {
        return;
    }

    if (!key) {
        return;

    var params = new window.URLSearchParams(window.location.search);
    if (value === undefined || value === null) {
        params.delete(key);
    } else {
        params.set(key, value);
    }

    url.search = params;

    window.history.replaceState({url: url}, null, url);

可以使用 URLSearchParams 和 History 接口轻松修改 URL 查询参数:

// Construct URLSearchParams object instance from current URL querystring.
var queryParams = new URLSearchParams(window.location.search);
 
// Set new or modify existing parameter value. 
//queryParams.set("myParam", "myValue");
queryParams.set("rows", "10");
 
// Replace current querystring with the new one.
history.replaceState(null, null, "?"+queryParams.toString());

或者,我们可以使用 pushState() 方法创建一个新条目,而不是使用 replaceState() 修改当前历史条目:

history.pushState(null, null, "?"+queryParams.toString());

我写了一个适用于任何选择的小辅助函数。您需要做的就是将类“redirectOnChange”添加到任何选择元素,这将导致页面使用新的/更改的查询字符串参数重新加载,等于选择的 id 和值,例如:

<select id="myValue" class="redirectOnChange"> 
    <option value="222">test222</option>
    <option value="333">test333</option>
</select>

上面的示例将添加“?myValue=222”或“?myValue=333”(如果存在其他参数,则使用“&”),并重新加载页面。

jQuery:

$(document).ready(function () {

    //Redirect on Change
    $(".redirectOnChange").change(function () {
        var href = window.location.href.substring(0, window.location.href.indexOf('?'));
        var qs = window.location.href.substring(window.location.href.indexOf('?') + 1, window.location.href.length);
        var newParam = $(this).attr("id") + '=' + $(this).val();

        if (qs.indexOf($(this).attr("id") + '=') == -1) {
            if (qs == '') {
                qs = '?'
            }
            else {
                qs = qs + '&'
            }
            qs = qs + newParam;

        }
        else {
            var start = qs.indexOf($(this).attr("id") + "=");
            var end = qs.indexOf("&", start);
            if (end == -1) {
                end = qs.length;
            }
            var curParam = qs.substring(start, end);
            qs = qs.replace(curParam, newParam);
        }
        window.location.replace(href + '?' + qs);

这就是我所做的。使用我的 editParams() 函数,您可以添加、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 = {},

  for (var i = 0; i < prmarr.length; i++) {

这是使用该query-string库的简单解决方案。

const qs = require('query-string')
function addQuery(key, value) {
  const q = qs.parse(location.search)
  const url = qs.stringifyUrl(
    {
      url: location.pathname,
      query: {
      ...q,
      [key]: value,
      },
    },
    { skipEmptyString: true }
  );
  window.location.href = url
  // if you are using Turbolinks
  // add this: Turbolinks.visit(url)
}
// Usage
addQuery('page', 2)

如果您不react使用react-router

export function useAddQuery() {
  const location = window.location;
  const addQuery = useCallback(
    (key, value) => {
      const q = qs.parse(location.search);
      const url = qs.stringifyUrl(
        {
          url: location.pathname,
          query: {
            ...q,
            [key]: value,
          },
        },
        { skipEmptyString: true }
      );
      window.location.href = url
    },
    [location]
  );

  return { addQuery };
}
// Usage
const { addQuery } = useAddQuery()
addQuery('page', 2)

如果您使用react的是react-router

export function useAddQuery() {
  const location = useLocation();
  const history = useHistory();

  const addQuery = useCallback(
    (key, value) => {
      let pathname = location.pathname;
      let searchParams = new URLSearchParams(location.search);
      searchParams.set(key, value);
      history.push({
        pathname: pathname,
        search: searchParams.toString()
      });
    },
    [location, history]

我的解决方案:

const setParams = (data) => {
    if (typeof data !== 'undefined' && typeof data !== 'object') {
        return
    }

    let url = new URL(window.location.href)
    const params = new URLSearchParams(url.search)

    for (const key of Object.keys(data)) {
        if (data[key] == 0) {
            params.delete(key)
        } else {
            params.set(key, data[key])
        }
    }

    url.search = params
    url = url.toString()
    window.history.replaceState({ url: url }, null, url)
}

然后只需调用“setParams”并传递一个包含您要设置的数据的对象。

例子:

$('select').on('change', e => {
    const $this = $(e.currentTarget)
    setParams({ $this.attr('name'): $this.val() })
})

在我的情况下,我必须在 html 选择输入更改时更新它,如果值为“0”,请删除该参数。如果对象键也为“null”,您可以编辑函数并从 url 中删除参数。

希望这对你们有帮助

        var urlParts = url.split("?");

        var baseUrl = urlParts[0];
        var queryString = urlParts[1];

        var itemSeparator = "";
        if (queryString) {

            var queryStringParts = queryString.split("&");

            for (var i = 0; i < queryStringParts.length; i++){

                if(queryStringParts[i].split('=')[0] != parameterName){

                    otherQueryStringParameters += itemSeparator + queryStringParts[i];

        var newQueryStringParameter = itemSeparator + parameterName + "=" + parameterValue;

        return baseUrl + "?" + otherQueryStringParameters + newQueryStringParameter;

我的功能支持删除参数

function updateURLParameter(url, param, paramVal, remove = false) {
        var newAdditionalURL = '';
        var tempArray = url.split('?');
        var baseURL = tempArray[0];
        var additionalURL = tempArray[1];
        var rows_txt = '';

        if (additionalURL)
            newAdditionalURL = decodeURI(additionalURL) + '&';

        if (remove)
            newAdditionalURL = newAdditionalURL.replace(param + '=' + paramVal, '');
        else
            rows_txt = param + '=' + paramVal;

        window.history.replaceState('', '', (baseURL + "?" + newAdditionalURL + rows_txt).replace('?&', '?').replace('&&', '&').replace(/\&$/, ''));
    }

我知道这是一个老问题。我已经增强了上面的功能来添加或更新查询参数。仍然只是一个纯 JS 解决方案。

                      function addOrUpdateQueryParam(param, newval, search) {

                        var questionIndex = search.indexOf('?');

                        if (questionIndex < 0) {
                            search = search + '?';
                            search = search + param + '=' + newval;
                            return search;
                        }

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

                        var indexOfEquals = query.indexOf('=');

                        return (indexOfEquals >= 0 ? query + '&' : query + '') + (newval ? param + '=' + newval : '');
                    }
