STRs = Str.split ("&");
for (i=0;i<strs.length;i++)

var num=str.indexof ("?")
Str=str.substr (num+1); Get all parameters
var arr=str.split ("&"); Each parameter is placed in an array
for (Var i=0;i < arr.length;i++) {
Num=arr[i].indexof ("=");
if (num>0) {
Name=arr[i].substring (0,num);
Value=arr[i].substr (num+1);
This[name]=value;
}
}
}
var request=new urlsearch (); Instantiated
alert (request.id);

For example, save this code as 1.html.

So I'm going to visit 1.html?id=test.

This is the time to get the test value.
