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 ())

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)
}

然后调用“setParams”并传递一个带有你想设置的数据的对象。

例子:

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

在我的情况下，我必须更新html选择输入时，它的变化，如果值是“0”，删除参数。如果对象键为“null”，则可以编辑该函数并从url中删除参数。

希望这对你们有帮助

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 : '');
                    }

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;

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。

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。
