如果您想在地址栏中更改url:

const search = new URLSearchParams(location.search);
search.set('rows', 10);
location.search = search.toString();

注意，改变位置。搜索重新加载页面。

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;

想想这个例子:

const myUrl = new URL("http://www.example.com?columns=5&rows=20");
myUrl.searchParams.set('rows', 10);
console.log(myUrl.href); // http://www.example.com?columns=5&rows=10
myUrl.searchParams.set('foo', 'bar'); // add new param
console.log(myUrl.href); // http://www.example.com?columns=5&rows=10&foo=bar

它会做和你要求的完全一样的事情。请注意URL必须有正确的格式。在你的例子中，你必须指定协议(http或https)

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 }

我认为你需要查询插件。

例如:

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

不管行当前的状态如何，这都可以工作。
