Can Somebody Tell Me If There's Any Errors In This Script?
I found the script below on Google that makes sure the visitor enters a zip code that matches the state they enter. I can't get it to work for some reason and I was wondering if anybody can point out any errors. It looks like the myzip in the third function should be zip correct?
Code:<script language="JavaScript" type="text/javascript"> <!-- // Expects a 5-digit zip code. Prevents user from entering 5 identical digits, as in 44444. function checkZipDigitsIdentical(zip){ sample=zip.substring(0,1) for(i=1;i<zip.length;i++){ if ((zip.substring(i,i+1))!=sample){ return } } error=1 msg=zip+" is not an acceptable zip code." } // Expects digits only, and checks that they aren't sequential, i.e. 23456 or 65432 function checkZipDigitsSequential(zip){ first=zip.substring(0,1) second=zip.substring(1,2) diff=parseInt(first)-parseInt(second) if(Math.abs(diff)!=1) return if (diff == -1){ //ascending order for(i=0; i<zip.length-1; i++){ if ((parseInt(zip.substring(i,i+1)))!=(parseInt(zip.substring(i+1,i+2))-1)) return } } if (diff == 1){ //descending order for(i=0;i<zip.length-1;i++){ if ((parseInt(zip.substring(i,i+1)))!=(parseInt(zip.substring(i+1,i+2))+1)) return } } error=1 msg=zip+" is not an acceptable zip code." } // Check to make sure the zip code matches the state. function checkIllegalZip(myzip,state) { var ZipAA = "340";
