The JS request function is used to obtain url parameters.

Copy codeThe Code is as follows:
Function request (strParame ){
Var args = new Object ();
Var query = location. search. substring (1 );

Var pairs = query. split ("&"); // Break at ampersand
For (var I = 0; I <pairs. length; I ++ ){
Var pos = pairs [I]. indexOf ('= ');
If (pos =-1) continue;
Var argname = pairs [I]. substring (0, pos );
Var value = pairs [I]. substring (pos + 1 );
Value = decodeURIComponent (value );
Args [argname] = value;
}
Return args [strParame];
