Here are a couple of JavaScript functions that can help in writing JavaScript validations. Case in point the space check Matt mentioned. function LTrim(in_data){ var out_data,index; out_data = in_data; while (out_data.length > 0){ sChar = out_data.charAt(0); if(sChar == " "){ out_data = out_data.substr(1); } else { break; } } return out_data; } function RTrim(in_data){ var out_data,index; out_data = in_data; while (out_data.length > 0){ sChar = out_data.charAt(out_data.length - 1); if(sChar == " "){ out_data = out_data.substr(0,out_data.length - 1); } else { break; } } return out_data; } function Trim(in_data){ return RTrim(LTrim(in_data)); } The call formatting is the same as CF so in Matts' function you could alter it like so: function textValidate(field) { var checkValue = Trim(field.value) if (checkValue.length == 0) { alert("Please enter some text in " + field.name); return false; } } -----Original Message----- From: "Alford, Gary L" <[EMAIL PROTECTED]> Sent: Jan 4, 2005 10:59 AM To: "'[email protected]'" <[email protected]> Subject: RE: OT: JavaScript Help...

"This" might help. ;-) <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <title>Untitled Document</title> <script language="javascript"> function textValidate(field) { if (field.value.length == 0) { alert("Please enter some text in " + field.name); return false; } } </script> </head> <body> <form> Field 1: <input type="text" name="field1" onBlur="textValidate(this);" /><br /> Field 2: <input type="text" name="field2" onBlur="textValidate(this);" /><br /> </form> </body> </html> Bear in mind that if you're checking to see if the user entered anything at all, you also need to handle if they just enter spaces, which a length check won't catch. I have an "isBlank" function laying around somewhere that checks both length and checks for space input--let me know if you're interested in that and I'll dig it up.
