通过删除一个参数及其值来清理URL

Question

我们说我有以下网址：

www.mydomain.com/default.aspx?param1=value1&param2=value2&param3=value3
OR
www.mydomain.com/default.aspx?param2=value2&param1=value1
OR
www.mydomain.com/default.aspx?param3=value3&param1=value1&param2=value2

如何只删除部分＆＃34; param1 = value1＆＃34;从那些使用jQuery或Javascript的URL地址？

Answer 1

试试这个： -

function RemoveParam(url, p) {
   return url
  .replace(new RegExp('[?&]' + p + '=[^&#]*(#.*)?$'), '$1')
  .replace(new RegExp('([?&])' + p + '=[^&]*&'), '$1');
}

var url='www.mydomain.com/default.aspx?param3=value3&param1=value1&param2=value2'

 alert(RemoveParam(url,'param1'));
