下面是一个使用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)

如果你使用react而不使用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)

如果你使用react和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]
  );

  return { addQuery };
}

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

PS: qs是从query-string模块导入的。

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)

let url= new url ("https://example.com/site.fwx?position=1&archiveid=5000&columns=5&rows=20&sorting=ModifiedTimeAsc") url.searchParams。设置(“行”,10) console.log (url.toString ())

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。

我扩展了Sujoy的代码来组成一个函数。

/**
 * 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"));

更新版本，也照顾到URL上的锚。

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 }
