我的函数支持删除参数

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。我增强了上面的功能，以添加或更新查询参数。仍然是一个纯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 : '');
                    }

使用javascript URL:

var url = new URL(window.location);
(url.searchParams.has('rows') ? url.searchParams.set('rows', rows) : url.searchParams.append('rows', rows));
window.location = url;

你也可以通过普通的JS来实现

var url = document.URL
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 = "&";
            }
        }
}
var rows_txt = temp+"rows=10";
var finalURL = baseURL+"?"+newAdditionalURL+rows_txt;

没有库，使用URL() WebAPI (https://developer.mozilla.org/en-US/docs/Web/API/URL)

function setURLParameter(url, parameter, value) {
    let url = new URL(url);
    if (url.searchParams.get(parameter) === value) {
        return url;
    }
    url.searchParams.set(parameter, value);
    return url.href;
}

这在IE: https://developer.mozilla.org/en-US/docs/Web/API/URL#Browser_compatibility上不起作用

我只是写了一个简单的模块来处理读取和更新当前url查询参数。

使用示例:

import UrlParams from './UrlParams'

UrlParams.remove('foo') //removes all occurences of foo=?
UrlParams.set('foo', 'bar') //set all occurences of foo equal to bar
UrlParams.add('foo', 'bar2') //add bar2 to foo result: foo=bar&foo=bar2
UrlParams.get('foo') //returns bar
UrlParams.get('foo', true) //returns [bar, bar2]

下面是我的代码UrlParams.(js/ts):

class UrlParams {

    /**
     * Get params from current url
     * 
     * @returns URLSearchParams
     */
    static getParams(){
        let url = new URL(window.location.href)
        return new URLSearchParams(url.search.slice(1))
    }

    /**
     * Update current url with params
     * 
     * @param params URLSearchParams
     */
    static update(params){
        if(`${params}`){
            window.history.replaceState({}, '', `${location.pathname}?${params}`)
        } else {
            window.history.replaceState({}, '', `${location.pathname}`)
        }
    }

    /**
     * Remove key from url query
     * 
     * @param param string
     */
    static remove(param){
        let params = this.getParams()
        if(params.has(param)){
            params.delete(param)
            this.update(params)
        }
    }

    /**
     * Add key value pair to current url
     * 
     * @param key string
     * @param value string
     */
    static add(key, value){
        let params = this.getParams()
        params.append(key, value)
        this.update(params)
    }

    /**
     * Get value or values of key
     * 
     * @param param string
     * @param all string | string[]
     */
    static get(param, all=false){
        let params = this.getParams()
        if(all){
            return params.getAll(param)
        }
        return params.get(param)
    }

    /**
     * Set value of query param
     * 
     * @param key string
     * @param value string
     */
    static set(key, value){
        let params = this.getParams()
        params.set(key, value)
        this.update(params)
    }

}
export default UrlParams
export { UrlParams }
