>I need to validate a Washington State driver's license. WA has a website where one can enter a D.L. # and get back info on whether the D.L. is valid. I haven't been able to figure out a technique for programmatically submitting information and getting back the response.

I tried building a look-alike-page, filling in the textbox with a value and then hitting the site from that one...thinking they may be looking for particular hidden inputs. That didn't work either. It's an HTTPS site and they're obviously, and correctly, security conscious, so I suspect it may be out of my control. However, I thought I'd see if anyone here has any suggestions.

Navigating to the URL above results in redirection to https://fortress.wa.gov/dol/ddl/dsd/Default.asp

Viewing the source one can see that a javascript navigate function is being called (the source for this can be found at (https://fortress.wa.gov/dol/ddl/dsd/Inc/common.js)

The navigate function is relatively simple taking two arguments (next, bypass) with a boolean variable (blnValid) used to control program flow. When called from default.asp bypass contains 0, so:

if(bypass == "0"){
	 blnValid = validateFields()

will call the validateFields() function, which is defined back in Default.asp, this only appears to contain

function validateFields(){
  return true;
}

so the salient code is the bit that populates hidden variables in frmScreen a form right at the bottom of default.asp and containing only hidden variables and then submits that form, using:

document.frmScreen.hdnNextScreen.value = next;
    document.frmScreen.hdnBypass.value = bypass

followed later by the

document.frmScreen.submit()

since next is login (all lower case) and not SAVE or EXIT.

You might want to focus on creating the frmScreen and copying its action.
