JavaScript - Password Validation In Javascript
function StrongPassword(Input) {
//var re = /(?=.*\d)(?=.*[a-z])(?=.*[A-Z]).{6,}/; //1 number,1 Uppercase,1 lowercase,6 characters var re = /^(?=.*\d)(?=.*[a-z])(?=.*[A-Z])/; //1 digit,1 Uppercase,1 lowercase if (re.test(Input)) { alert('Strong Password'); } else { alert('Weak pwd'); } } Help to get correct output.... both the expr will execute the else block only... Similar TutorialsI'm having trouble getting two password boxes to work on the same page, which I created using the JavaScript Kit Encrypted Password Generator (http://www.javascriptkit.com/epassword/index.htm). I've used the code that this generator produces, with some modifications as given by cheesebagpipe (http://www.codingforums.com/showthread.php?t=14646). These changes enable the user to press the keyboard's enter key to submit the password (as an alternative to clicking the submit button), and will also refocus the text box and select the text in it if the user enters the wrong password. The code works fine on pages with just one box (e.g. http://www.mistymusic.co.uk/StLuke's.html), but what changes are needed to make two work on the same page? (I'm new to web design and clueless when it comes to JavaScript, which I know isn't the most secure method of password protection, but will do for now). At the moment, on pages with two boxes (e.g. http://www.mistymusic.co.uk/BEAP.html), neither of the boxes work; this appears in the address bar instead: 'http://www.mistymusic.co.uk/BEAP.html?password2=help!' ('help!'=whatever has been entered in the text box). The full code for both boxes is given below. Code: <div id="passwordBoxes">
<div id="password2">
<form name="password1" onsubmit="submitentry();return false;">
<span class="WhiteLogin">Keyboard classes login</span>
<input name="password2" type="password" class="AlignedFormBoxes" size="15" />
<input type="button" class="AlignedFormBoxes" value="Login" />
</form>

Any help would be a lifesaver - thanks in advance! I am struggling trying to get this bit of code I've written to work. It should validate a password that is 10 characters long, starts with a D and includes 1 *. Even if I blank out two of the while statements and only use the charAt while statement it still fails to loop back. Any ideas? function validatePassword() { //declare and initialise variables var intCount = 0; var intCharCount = 7; var intAstrixCount =0; var strPassword = parseInt(prompt("Please enter password", "")); while (strPassword.length < intCount) { alert ("Your password must be at least 10 characters long"); strPassword = parseInt(prompt("Please enter password", "")); intCount++; } while (strPassword.charAt(0) != "a") { alert ("Your password does not start with a D"); strPassword = parseInt(prompt("Please enter password", "")); intCount++; } while (intAstrixCount != 1) { alert ("Your password does not contain an *"); strPassword = parseInt(prompt("Please enter password", "")); intCount++; } alert ("Your password is correct"); } Working on college assignment, cant figure it out and need help! Basically a form that asks the user to fill in a valid email and password (ill give them the password), doesnt matter if it isnt secure, or if the email accepts dodgy emails (im just verifying the @ and a . and that is ok for the purpose of this. Anyway been trying with this code for ages now and cant see what is wrong but it isnt working, ive swapped it around and at times it does check that it is a valid email, sometimes it allows empty inputs. here is the code <script type="text/javascript"> function validateForm() { var x=document.forms["myForm"]["email"].value var y=document.forms["myForm"]["password"].value var atpos=x.indexOf("@"); var dotpos=x.lastIndexOf("."); if (atpos<1 || dotpos<atpos+2 || dotpos+2>=x.length) { alert("Not a valid e-mail address"); return false; } </script> I think i need something like && (y!="123") around the 'if' statement, but not a clue how or where it goes. Basically im going to set the password to 123 so dont have to allow for caps etc. Easiest way to do this, anyone plleeeeeaaasseee?? Kind regards Alan I know this is not very secure, but there is a problem with this and I am not sure how to go on. Code: <form> <input type="text" name="password"/> <input type="button" onclick="check()"/> </form> What is wrong with my javascript? Code: function check (){
if(password=="pass1"){
alert('Password is correct!')
}
}
I'm having trouble with a Javascript pop up box not appearing on Internet Explorer. I have tested it with IE7 and IE8 with no success. It works on Firefox 3.6.3 and Opera. On internet explorer this yellow bar appears; However, once clicked and given temporary permission the page reloads not showing the pop up box and the yellow bar is still present. I have re-created the situation here; http://html.comuf.com/ problem.html is the page I need help on. The correct password is real which redirects you to real.html. I am open to using new scripts but this line/function is crucial; Code: location.href= password + ".html"; This problem is for a friend of mine who does design work, his client is having trouble with this. The pop up box must appear after allowed temp through IE, or even better no user allowance is required while keeping the password +.html code. P.S. I plan to stick around and learn after this gets answered! I have a need of a Java Script function to encrypt passwords into Salted SHA in a format similar to the way LDAP stores it. Does anyone know if this has ever been done? Hello I am new at Javascript. Please help me this: I have a form and a checkbox: Code: <input name="pass" type="password" class="textfield" /> <input type="checkbox" class="check"> Click here to show/hide password If I the checkbox is checked, it will show the password in the form, it means Code: <input name="pass" class="textfield" /> if not, the input form is: Code: <input name="pass" type="password" class="textfield" /> Hi, I know nothing about javascript but I was able to handle the instructions to install the login/password featu http://www.javascriptkit.com/script/...ginpass2.shtml works great! however, when someone views the source code, they're able to see what the password is. additionally they can see the url of the page it would take them if they entered the password. how do i protect against this vulnerability? thanks in advance! I have an older website consisting of frames (html). Now I want to password protect one page. So far I added the following Javascript which I found on youtube: <SCRIPT> function passWord() { var testV = 1; var pass1 = prompt('Please Enter Your Password',' '); while (testV < 3) { if (!pass1) history.go(-1); if (pass1.toLowerCase() == "letmein") { alert('You Got it Right!'); window.open('protectpage.html'); break; } testV+=1; var pass1 = prompt('Access Denied - Password Incorrect, Please Try Again.','Password'); } if (pass1.toLowerCase()!="password" & testV ==3) history.go(-1); return " "; } </SCRIPT> <CENTER> <FORM> <input type="button" value="Enter Protected Area" onClick="passWord()"> </FORM> </CENTER> This works but the protected page opens in a new window not in the main frame. What do I have to add and where? Will search engines pick up this page and display it on the public? Thank you. CT for some reason this is not working can anyone tell me why? Code: <script language="JavaScript" type="text/javascript">

Hi. I am trying to do some sim[ple form validation using javascript. I have a simple html file Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Send Card</title> <script language="JavaScript" src="gen_validatorv31.js" type="text/javascript"></script> </head> <body> <form action="getName.php" onsubmit="return validate_form(this);"> Receiver (To): <input type="text" name="name"><br> Sender (From): <input type="text" name="sender"><br> Email: <input type="text" name="email"><br> <input type="submit" value="Submit"> </form> </body> </html> Which calls up my javascript and php file (The php file should only be used when the javascript has found no errors). Now I have a js file which does some validation Code: <script type="text/javascript">
function validate_required(field,alerttxt) {
with (field) {
if (value==null||value=="") {
alert(alerttxt);
return false;
}
else {
return true;
}
}
}
function validate_email(field,alerttxt) {
with (field) {
apos=value.indexOf("@")
dotpos=value.lastIndexOf(".")
if (apos<1||dotpos-apos<2) {
alert(alerttxt);
return false;
} else {
return true;
}
}
}
function validate_form(thisform) {
with (thisform) {
if (validate_required(name,"Please specify your name!")==false) {
name.focus();
return false;
}
if (validate_required(sender,"Please specify the receivers name!")==false) {
sender.focus();
return false;
}
if (validate_required(email,"Email must be filled out!")==false) {
email.focus();
return false;
}
if (validate_email(email,"Not a valid e-mail address!")==false) {
email.focus();
return false;
}
}
}
</script>
When I run it on my server, I get the form and enter nothing into it, I just click submit. However, it goes straight to the php file and brings up my flash movie, which it shouldnt do. When nothing is entered, the js file should return the error. I thought I had everything set up correctly, but obviously not. Can someone see where I am going wrong? cheers Hi guys, just need help so when there is no input into card number, postcode, what are you after, delivery address an error message comes up. Also I need to make it so when someone puts numbers in the first and last name or letters in the postcode it will come up error. I have done this for first and lastname but when I copy my code and try and put it on the others then no javascript works. thanks for your help Code: <html>

I am new to this forum.. and I am hoping to get help with this javascript validation for my form for my assignment. trying to validate multiple fields. I have never done javascript, so with my limited understanding from Google, I put together code snippets. Problems: 1. How can I get one message box when the user presses submit indicating all failed validation at one time 2. The expired credit card validation doesnt work 3. Cant seem to find a good "confirm password" script 3. The form does not submit if all the fields are correct. <script language="javascript"> <!-- function checkAge() { var bday=parseInt(document.forms[0].txtBday.value); var bmo=(parseInt(document.forms[0].txtBmo.value)-1); var byr=parseInt(document.forms[0].txtByr.value); var byr; var age; var now = new Date(); tday=now.getDate(); tmo=(now.getMonth()); tyr=(now.getFullYear()); { if((tmo > bmo)||(tmo==bmo & tday>=bday)) { age=(tyr-byr) } else { age=(tyr-(byr+1)) } if (age<18) { alert ("you must be over 18 years"); return false; } else { return true; } } } //--> function checkEmail() { var x=document.getElementById("email").value; var atpos=x.indexOf("@"); var dotpos=x.lastIndexOf("."); if (atpos<1 || dotpos<atpos+2 || dotpos+2>=x.length) { alert("Not a valid e-mail address"); return false; } { return true; } } function onlyNumbers(evt) { var e = event || evt; // for trans-browser compatibility var charCode = e.which || e.keyCode; if (charCode > 31 && (charCode < 48 || charCode > 57)) return false; { return true; } } function checkCardNumber() { var x = document.getElementById("cardNumber").value; if (x.length<16) { alert("Your Credit Card Number must be 16 digits"); return false; } { return true; } } function checkSecurityCode() { var y = document.getElementById("securityCode").value; if (y.length<3) { alert("Your Security number must be three digits"); return false; } { return true; } } function ValidateExpDate() { var ccExpYear = 20 + $F('<%= expYear.ClientID%>'); var ccExpMonth = $F('<%= expMonth.ClientID%>'); var expDate=new Date(); expDate.setFullYear(ccExpYear, ccExpMonth, 1); var today = new Date(); if (expDate<today) { alert("card expired"); // Credit Card is expire return false; } else { // Credit is valid return true; } } function runall() { checkAge(); checkEmail(); checkCardNumber(); checkSecurityCode(); { return false;} } </script> 1.I want to retain the value of the item selected from the drop down list even if the validation fails 2. The input element should be hghlighted red in colour which fails the validation <html> <script type="text/javascript"> <!-- function validate_form1 ( ) { valid = true; if ( document.contact_form1.question1.value=="" || document.contact_form1.question2.value == "" ) { alert ( "Select at least one option." ); //document.getElementById("question1").focus(); document.getElementById('contact_form1').question1.focus(); valid = false; } return valid; } function validate_form2 ( ) { valid = true; if ( document.contact_form2.question1.value=="" || document.contact_form2.question2.value == "" ) { alert ( "Select at least one option." ); //document.getElementById("question1").focus(); valid = false; } return valid; } //--> </script> <table border="5" width="300"> <tr> <td> <form name="contact_form1" action="DBsaving.php" method="post" onSubmit="return validate_form1 ( );"> 1.
