JavaScript - Matching Two Passwords
Hi all,
I'm trying to match two passwords to one another. The user enters the password into two fields and onblur from the second field, the function runs. Here is my code: Code: function validatePassword(inputField, inputField2, helpText, helpMessage) {
// First see if the input value contains data
if (!validateNonEmpty(inputField, helpText))
return false;
var inputField = document.getElementById('inputField').firstChild.nodeValue
var inputField2 = document.getElementById ('inputField2').firstChild.nodeValue
}
if (inputField !== inputField2) {
// The data is invalid, so set the help message and return false
if (helpText != null)
helpText.innerHTML = helpMessage;
}
else {
// The data is OK, so clear the help message and return true
if (helpText != null)
helpText.innerHTML = "";
}
};
Code: document.getElementById('password2').onblur = function() {
validatePassword(this, document.getElementById('password'), document.getElementById('password2_help'), "<p>Passwords don't match</p>'");
};
I am passing a help text to a span element inside the form: Code: <div class="fieldset"> <label for="password2">Confirm:</label> <input type="password" id="password2" name="password2" /> <span id="password2_help" class="help"></span><br/> </div><!--fieldset--> What's going on here? As far as I can tell it this should be working. Thanks, Andrew Similar TutorialsNeed to write a script that will ask for password and then give an alert with either successful login or unsuccessful login. It needs to use the while loop and I need for the script to accept four different passwords. I can script it for one password but can not figure out how to get it to work for other the passwords. Unfortunately I don't know computer programming and very little html and was allowed to sign up for a course that is too advanced for me and I can't drop it because I will lose my financial aid so with I am really struggling in this class and the assignments do not really go with the textbook and examples provided. Here is the code I have so far: <html> <body> <script type="text/javascript"> var password = new Array ("midland", "baycity", "saginaw", "delta"); var tries = 3; password = prompt("Enter password", ""); while (password != "midland" && tries > 0) { alert("Incorrect password - You have " + tries + " more tries"); password = prompt("Enter password", ""); tries--; } if (password == "midland") alert("Login Successful"); else alert ("Login Failed - Please Try Later"); </script> </body> Pls help me as to how to code for the password form in html and then make it to be recognized in a notepad. what i mean is... when logging in or when entering a password the html should look or match it in a notepad and see if its the correct one. and to at least allow people to register and save the passwords in that same notepad. Thanks in advance Ok, I have no idea how to really even explain what's been asked of me, but it's seems to me that this could be a bit beyond my knowledge. We're creating an alternate reality game which starts with a series of questions that people can choose from two answers. The answers will determine which path the person will travel. They'll be given a password at the end of the series of questions. There are three possible paths, which means three possible passwords given. On the same page, beneath the questions would be a text box with a "submit" button. The password they are given would be typed in there, and then they'd proceed to the proper page. This keeps from people being able to "skip" the questions portion. What they'd proceed to next is a video which is currently being made for our event, which has hidden puzzles and clues in it to find the next password. Rinse and repeat... My problem? How the heck do I make that box and submit button and password all work together when I have more than one password? Even more so, how do I make the password/submit button direct someone to the correct URL (without revealing the URL, and also prevents anyone from copying the URL and sharing it to bypass the password request)? For example: Questions are complete and the password "invention" is given. The person types in the word invention and presses submit. It directs the to www.url.com/game1 automatically. While someone else will come in, answer the questions, and the password "intelligence" would be given. That person types in the word intelligence and presses submit into the same box, using the same button that the person who typed in the word invention typed in. But this person would instead be directed to www.url.com/game2 If either person shared the link they were directed to, then it'd prompt people to put in a password before letting them in. How in the darn world do I make this happen?? LOL! Thanks in advance for any time, advice, or tutorials provided! ---------------------------------------- Added later.... I might need to go ahead and ask this as well.. since it got me to thinking.. How would I go about hiding the URL as well. I'm only interested in doing it for the game side of the site to keep from people sharing that URL and stripping the "fun" away from the game. Hopefully it is something simple? I'm fairly new at coding. My knowledge is no where as vast as I see many others here are. So if you should decide to have the patience to assist me, please be specific in steps like you are describing this to your kid who has no idea what you're talking about. I hate to present it that way, but I don't want to annoy anyone by stating I don't understand. I have the code for the page below that has form with a text box for a email address. I am doing this exercise trying to understand the concepts of pattern matching in a function. ***My expression on needs to tests for *** 1. One or more word characters= /\w+ 2. one period= \.\ 3. one hyphen sign= \-\ 4. two or more characters that a-z, A-Z, 0-9, period or hyphen= \W+\. I have a alert message that display when the user has returned a invalid address. I don't need regex for testing an entire email address that is out of the scope that I am studying. I have wrote a function but to honest I am not sure where I have gone wrong and not exactly where I need to go to execute it correctly. <!DOCTYPE html> <html> <head> <title>Lab 2 Part 3</title> <meta charset="UTF-8" /> <body> <script> function validation(address) { var ok= address.search(/\w+\.\-\@\W+); if (ok==0) return true; else alert("please enter a valid email address"!!) return false; } </script> <form action="http://yahoo.com/formtest.php" method="post" onsubmit="return validation();"> <p> <label> Email Address: <input type="text" name="address" size="30"/> </label> </p> <input type="submit" value="Submit" /> </form> </body> </html> So I have created a simple calendar (http://www.akapa.org/newsite/events/calendar.htm) and I have a bunch of "More Info" buttons I made from cells. In a table cell to the right are a bunch of hidden DIV's that all appear when you rollover a "More Info" button, obviously giving more details about the calendar date/event. My problem is that I have to give an exact "top" css position to every one of these hidden div's every single time I add a new event to the calendar. I want to dynamically tell each hidden div to match the "top" css position to match the top position of each "More Info" button. How do I do that? Hi All, Following pattern in bold is present in a variable bigvar which has around 100 characters. Variable test may vary var test = CONFIG_ID CONFIG_ID="_N/D1/N1/S4/P1/E1%231.1.1/T 3" Here is what I have tried: var RE = new RegExp (test+"=[A-Za-z0-9_%\"\.\/]+\s{2}[0-9]+"); var matched_val = bigvar.match(RE); alert(matched_val); It is giving null as match. Can anyone help me on this ? Thanks, Vinay I'm writing a matching game. I have uploaded an example. I want to be able to read the current image rather than the default image as a variable to compare in an IF statement. http://www.mediafire.com/file/8nq4s5...a/matching.zip I have an autocomplete script but it's currently returning results in a character is in the name anywhere at all, what I need it to do is only return matches if the characters are in sequence only. Example of how it is now if you type S it will return: Science Host Pass What I need it to do is only return a match if the first character is an S, and so on down the line in order. So if you type sam it should only return matches where the first 3 letter are sam in the order it's typed. Here's how the regexp is now: return value.replace(new RegExp("(?![^&;]+(?!<[^<>]*)(" + term.replace(/([\^\$\(\)\[\]\{\}\*\.\+\?\|\\])/gi, "\\$1") + ")(?![^<>]*>)(?![^&;]+", "gi"), "<strong>$1</strong>"); Hello! I'm in need to be able to create a matching picture game, in which I have rougly 9 images to be able to match, but 18 in total. I have started with a thought of having a button that; when pressed it will disappear and show the image that is within the function. Progress; I am able to press the button and let the image load, but in this case everything goes fine (image resized, not sure about the id though) but the image doesn't show, it just shows an [X] yet when I just put Code: <script language="Javascript" type="text/javascript">
function callImage(){
document.write("<img src=\"images/truck0.jpg">")
}
</script>
The function works fine when I press the button. Any tips? Thank you! Full Code so Far: Code: <head>
<script language="Javascript" type="text/javascript">
function callImage(){
document.write("<img src=\"images/truck0.jpg id=\"pic\" width=\"150\" height=\"150\">")
}
</script>
</head>
<body>
<form>
<input type="button" value="Display" onClick="callImage()"/>
</form>

Here's another problem I'm having, I have to validate credit card types. My code worked originally. I simply checked the prefix for each type then verified the length with an if statement. However, I decided to change the code so that only numbers would work after the prefix (as the old code would have allowed any character). This is the code I have: Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

var ccNum = myForm.cardNum.value;
if (myForm.cardType.selectedIndex == 0)

ccType = "Visa";
}
else if (myForm.cardType.selectedIndex == 1)
{
ccType = "MasterCard"

Upon pressing the button nothing happens, I'm completely unsure where I went wrong as all the code seems valid... Please help. Thanks in advance. Hi I am currently writing a program to analyse (to a degree), the points scored in a dance contest. The program mainly works so far. However I am struggling to conclude the program end. Using an if statement, I would like to compute if a dance-off is required, looping through the combinedPointsArray and determining if 2 or more numbers hold the higest score and are equal. The aim is to provide: Maximum number of combined points The couples and their combined points The couples names with the highest points If two or more couples have equal highest combined points - output whether a dance-off is required. This is my program so far: Code: <HTML>

var combinedPointsArray = new Array (judgesPointsArray.length)

Any help would be really appreciated. I have spent so long on this; consequently I am pulling my hair out. Regards hyp3r Hi Having a small problem with writing out the matches from an array using a For loop. I have two arrays, lets say arrayA and arrayB. In arrayB are numbers which are a number of miles, ie 1,2,6,4,5,6,6. And in arrayA are the days of the week. Each day of the week is associated with a mileage, ie Mon = 1, Tues = 2 etc. My script has found the largest mileage in arrayB. Next I have to find the days of the week that match this highest mileage and write these out, along the lines of "The highest mileage was 6 run on Wed, Sat, Sun." I have managed to get a For loop to work with this BUT..... I can only get it to write out the first instance of the day the match is found. ie "The highest mileage was 6 run on Wed," Pointers in the right direction to help me solve this problem would be much appreciated. [CODE] maximumDistanceIndex = 0; for (var distance = 1; distance < distanceArray.length; distance = distance + 1) { if (distanceArray[distance] > distanceArray[maximumDistanceIndex] ) { maximumDistanceIndex = distance document.write ('The maximum distance was ' + maximumDistance + ' km' + ' run on ' + dayArray[maximumDistanceIndex] ); } } [CODE] Hey, I'm writing a piece of code, using a given code as an example, but few things are confusing to me, if you could just explain me step by step what it does, I would really appreciated. Code: function getGeneticCodeString (type) {
if ((type.toLowerCase() == "standard") || (type.toLowerCase() == "transl_table=1"))
{
return "/gc[acgturyswkmbdhvn]/=A," +
// Here I know that the three letter combination HAS to begin with 'gc'
// can be followed by a,c,t,g or u.
// What do the other letter represent?
"/[tu]g[ctuy]/=C," +
// Begins with either 't' or 'u', middle symbol is 'g'
// third symbol can be c, t, or u ('u' can be used only if it begins with 'u'.
// what is the 'y' for in the second square brackets for??
"/ga[agr]/=E " ;
// Must start with 'ga' followed by 'a' or 'g'.
// What is 'r' for?
}
}
Hope, I didn't confuse anybody. Thank you. |
