我有这个URL:

site.fwx?position=1&archiveid=5000&columns=5&rows=20&sorting=ModifiedTimeAsc

我需要的是能够改变'行' url参数值我指定的东西,让我们说10。如果“行”不存在,我需要将它添加到url的末尾,并添加我已经指定的值(10)。


当前回答

四年后,在我学到了很多东西之后,来回答我自己的问题。特别是你不应该对所有事情都使用jQuery。我已经创建了一个简单的模块,可以解析/stringify查询字符串。这使得修改查询字符串变得很容易。

query-string的用法如下:

// parse the query string into an object
var q = queryString.parse(location.search);
// set the `row` property
q.rows = 10;
// convert the object to a query string
// and overwrite the existing query string
location.search = queryString.stringify(q);

其他回答

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 ())

一种现代的方法是使用基于URLSearchParams的本地标准。所有主流浏览器都支持它,除了IE,因为IE提供了腻子

const paramsString = "site.fwx?position=1&archiveid=5000&columns=5&rows=20&sorting=ModifiedTimeAsc"
const searchParams = new URLSearchParams(paramsString);
searchParams.set('rows', 10);
console.log(searchParams.toString()); // return modified string.

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)

在URLSearchParams文档中,有一种非常干净的方法可以做到这一点,而且不会影响历史堆栈。

// URL: https://example.com?version=1.0
const params = new URLSearchParams(location.search);
params.set('version', 2.0);

window.history.replaceState({}, '', `${location.pathname}?${params}`);
// URL: https://example.com?version=2.0

类似地,删除参数

params.delete('version')
window.history.replaceState({}, '', `${location.pathname}?${params}`);
// URL: https://example.com?

     // URI = scheme:[//authority]path[?paramName1=paramValue1&paramName2=paramValue2][#fragment]
     // call by: uri = uri.setUriParam("as","md")
     String.prototype.setUriParam = function (paramName, paramValue) {
        var uri = this
        var fragment = ( uri.indexOf('#') === -1 ) ? '' : uri.split('#')[1]
        uri = ( uri.indexOf('#') === -1 ) ? uri : uri.split('#')[0]
        if ( uri.indexOf("?") === -1 ) { uri = uri + '?&' }
        uri = uri.replace ( '?' + paramName , '?&' + paramName)
        var toRepl = (paramValue != null) ? ('$1' + paramValue) : ''
        var toSrch = new RegExp('([&]' + paramName + '=)(([^&#]*)?)')
        uri = uri.replace(toSrch,toRepl)
        if (uri.indexOf(paramName + '=') === -1 && toRepl != '' ) {
           var ampersandMayBe = uri.endsWith('&') ? '' : '&'
           uri = uri + ampersandMayBe + paramName + "=" + String(paramValue)
        }
        uri = ( fragment.length == 0 ) ? uri : (uri+"#"+fragment) //may-be re-add the fragment
        return uri
     }
