JS Get URL Pass parameters

Transferred from: http://www.cnblogs.com/gaojun/archive/2013/06/09/3129412.html

Here is a JavaScript client solution that gets the URL with the questring parameter, equivalent to the ASP's request.querystring,php $_get
Function:

<Script language="javascript">functionGetRequest() {   varurl = location.search; //获取url中"?"符后的字串   vartheRequest = newObject();   if(url.indexOf("?") != -1) {      varstr = url.substr(1);      strs = str.split("&");      for(vari = 0; i < strs.length; i ++) {         theRequest[strs[i].split("=")[0]]=(strs[i].split("=")[1]);      }   }   returntheRequest;}</Script>

Then we get the corresponding parameter value by calling this function:

<script language= "JavaScript" >
var Request = new Object ();
Request = Getrequest ();
var parameter 1, Parameter 2, parameter 3, parameter n;
Parameter 1 = request[' parameter 1 '];
Parameter 2 = request[' parameter 2 '];
Parameter 3 = request[' parameter 3 '];
Parameter n = request[' parameter n '];
</Script>
This gets the parameter with the same name in the URL string

Second, the regular analysis method.
function getquerystring (name) {
var reg = new RegExp ("(^|&)" + name + "= ([^&]*) (&|$)", "I");
var r = window.location.search.substr (1). Match (REG);
if (r!=null) return (r[2]); return null;
}
Alert (getquerystring ("parameter name 1"));
Alert (getquerystring ("parameter Name 2"));
Alert (getquerystring ("parameter name 3"));

additional parameters to get introduced:Sets or gets the file name or path specified by the object.
alert (window.location.pathname);

Sets or gets the entire URL as a string.
alert (WINDOW.LOCATION.HREF);

Sets or gets the port number associated with the URL.
alert (Window.location.port);


Sets or gets the protocol portion of the URL.
alert (Window.location.protocol);

Sets or gets the segment behind the pound sign "#" in the href attribute.
alert (Window.location.hash);

Set or get the hostname and port numbers for the location or URL.
