copied!<p>I have a form validation script all the validation work. but the fields clear up when the alert about the passwords not matching shows up? how can i avoid that? </p> <pre><code> <script type="text/javascript"> function formValidator(){ // Make quick references to our fields var FNAME = document.getElementById('FNAME'); var LNAME = document.getElementById('LNAME'); var EMAIL = document.getElementById('EMAIL'); var GENDER = document.getElementById('GENDER'); var ADDRESS = document.getElementById('ADDRESS'); var CONTACTNO = document.getElementById('CONTACTNO'); var PASSWORD = document.getElementById('PASSWORD'); var PASSWORD2 = document.getElementById('PASSWORD2'); // Check each input in the order that it appears in the form! if(isAlphabet(FNAME, "Please enter only letters for your first name")) { if(isAlphabet(LNAME, "Please enter only letters for last name")) { if(emailValidator(EMAIL, "Please enter a valid email address")) { if(madeSelection(GENDER, "Please Choose a Gender")) { if(isAlphanumeric(ADDRESS, "Numbers and Letters Only for Address")) { if(isNumeric(CONTACTNO, "Please enter only numbers for Contact No.")) { if(lengthRestriction(PASSWORD, 6)) { if (PASSWORD2 != PASSWORD) { alert ("You did not enter the same new password twice. Please re-enter your password."); return true; } } } } } } } } return false; } </code></pre> <p>i think that there is no problem with my other functions? </p> <pre><code> function notEmpty(elem, helperMsg){ if(elem.value.length == 0){ alert(helperMsg); elem.focus(); // set the focus to this input return false; } return true; } function isNumeric(elem, helperMsg){ var numericExpression = /^[0-9]+$/; if(elem.value.match(numericExpression)){ return true; }else{ alert(helperMsg); elem.focus(); return false; } } function isAlphabet(elem, helperMsg){ var alphaExp = /^[a-zA-Z]+$/; if(elem.value.match(alphaExp)){ return true; }else{ alert(helperMsg); elem.focus(); return false; } } function isAlphanumeric(elem, helperMsg){ var alphaExp = /^[0-9a-zA-Z]+$/; if(elem.value.match(alphaExp)){ return true; }else{ alert(helperMsg); elem.focus(); return false; } } function lengthRestriction(elem, min){ var uInput = elem.value; if(uInput.length >= min){ return true; }else{ alert("Please enter atleast " +min+ " characters"); elem.focus(); return false; } } function madeSelection(elem, helperMsg){ if(elem.value == "Please Choose"){ alert(helperMsg); elem.focus(); return false; }else{ return true; } } function emailValidator(elem, helperMsg){ var emailExp = /^[\w\-\.\+]+\@[a-zA-Z0-9\.\-]+\.[a-zA-z0-9]{2,4}$/; if(elem.value.match(emailExp)){ return true; }else{ alert(helperMsg); elem.focus(); return false; } } </script> </code></pre> <p>i guess that i'm doing this part wrong?? but i don't know how to fix it? please help.</p> <pre><code>if (PASSWORD2 != PASSWORD) { alert ("You did not enter the same new password twice.
