Using JScript to traverse the Request form parameter collection

There is an Enumerator object under JScript that can traverse the collection. According to its documentation, I wrote the following program, which can traverse the entire Request.QueryString collection. Copy the code. The code is as follows:

var params = new Enumerator(Request.QueryString);

while (!params.atEnd()) {

Response.Write(params.item() + : + Request.QueryString(params.item()) + <br />);

params.moveNext();

}

The fly in the ointment is that the Request object itself is not a collection, so the Request object cannot be traversed. The following line of code will report an error:

Copy the code code as follows:

var params = new Enumerator(Request);
