Static html file js reads url parameters

In the future, do not jump to the background code to get the parameters contained in the URL.

 

 

Code

1. string segmentation analysis.
Here is a JAVASCRIPT client solution for obtaining URL parameters with QUESTRING, equivalent to asp's request. querystring, PHP's $ _ GET

Function:
<Script language = "javascript">
Function GetRequest (){
Var url = location. search; // get the url "? "Character String
Var theRequest = new Object ();
If (url. indexOf ("? ")! =-1 ){
Var str = url. substr (1 );
Strs = str. split ("&");
For (var I = 0; I <strs. length; I ++ ){
TheRequest [strs [I]. split ("=") [0] = unescape (strs [I]. split ("=") [1]);
}
}
Return theRequest;
}
</Script>

Then, we can call this function to obtain the corresponding parameter values:
<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>
Obtain the parameter with the same name in the url string.

Ii. Regular Expression Analysis.

Function GetQueryString (name ){
Var reg = new RegExp ("(^ | &)" + name + "= ([^ &] *) (& | $)", "I ");
Var r = window. location. search. substr (1). match (reg );
If (r! = Null) return unescape (r [2]); return null;
}
Alert (GetQueryString ("parameter name 1 "));
Alert (GetQueryString ("parameter name 2 "));
Alert (GetQueryString ("parameter name 3 "));
