下面是使用锚HTML元素的内置属性的另一种方法:

处理多值参数。 没有修改#片段或查询字符串本身以外的任何内容的风险。 可能会更容易读?但是它更长。

var a = document.createElement('a'), getHrefWithUpdatedQueryString = function(param, value) { return updatedQueryString(window.location.href, param, value); }, updatedQueryString = function(url, param, value) { /* A function which modifies the query string by setting one parameter to a single value. Any other instances of parameter will be removed/replaced. */ var fragment = encodeURIComponent(param) + '=' + encodeURIComponent(value); a.href = url; if (a.search.length === 0) { a.search = '?' + fragment; } else { var didReplace = false, // Remove leading '?' parts = a.search.substring(1) // Break into pieces .split('&'), reassemble = [], len = parts.length; for (var i = 0; i < len; i++) { var pieces = parts[i].split('='); if (pieces[0] === param) { if (!didReplace) { reassemble.push('&' + fragment); didReplace = true; } } else { reassemble.push(parts[i]); } } if (!didReplace) { reassemble.push('&' + fragment); } a.search = reassemble.join('&'); } return a.href; };

这样做的目的是:

function updateQueryString(url, key, value) {
    var arr =  url.split("#");
    var url = arr[0];
    var fragmentId = arr[1];
    var updatedQS = "";
    if (url.indexOf("?") == -1) {
        updatedQS = encodeURIComponent(key) + "=" + encodeURIComponent(value);
    }
    else {
        updatedQS = addOrModifyQS(url.substring(url.indexOf("?") + 1), key, value); 
    }
    url = url.substring(0, url.indexOf("?")) + "?" + updatedQS;
    if (typeof fragmentId !== 'undefined') {
        url = url + "#" + fragmentId;
    }
    return url;
}

function addOrModifyQS(queryStrings, key, value) {
    var oldQueryStrings = queryStrings.split("&");
    var newQueryStrings = new Array();
    var isNewKey = true;
    for (var i in oldQueryStrings) {
        var currItem = oldQueryStrings[i];
        var searchKey = key + "=";
        if (currItem.indexOf(searchKey) != -1) {
            currItem = encodeURIComponent(key) + "=" + encodeURIComponent(value);
            isNewKey = false;
        }
        newQueryStrings.push(currItem);
    }
    if (isNewKey) {
        newQueryStrings.push(encodeURIComponent(key) + "=" + encodeURIComponent(value));
    }
    return newQueryStrings.join("&");
}   

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);
}

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)

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

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

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）;
