Anybody want to help with a JavaScript assignment?

So I've spent at least 4 hours trying to get this script to work, and I'm at a loss. My Google-fu has failed me. With the following script (in spoiler) I have to " use a loop so that if the user enters incorrect data three times a message box comes up indicating that three is the limit and that they can no longer attempt log ons." I just need an alert box to pop up, I don't need to actually lock the user out. I know this is ridiculous and would never be used in real life, but this is what the professor wants. I'm sorry if this is an easy question, I've honestly learned nothing this entire semester because this guy doesn't seem to like to teach. Any help would really be appreciated.

You might try tested, I've seen threads there of people asking for help with code and getting some.  I don't know much Java, not enough to help anyways.

Thanks, I'll try those forums as well!

Hint: use the object that you actually sent instead of the word frmRegister, which you haven't defined before using.  Also use Firebug on Firefox to check for yourself that the error starts on the first line of your code. in your validate(form) function.  If not, just check where the error happens using Firebug.  It will tell you which line in your page causes the error.

Edit: Sorry I mean second line in your function.  First line is fine as it is just a variable declaration that looks fine.

It would appear that Mozilla really likes JavaScript, because they have a full reference available fo' free, online. This doesn't look all that different from the VBA and Cocoa that I've dabbled in before. Definitely look at using the reference as a source besides just the book, because the online documentation is almost always ridiculously helpful, since it contains full definitions of every aspect of the code.

" @proggykins: I didn't look at it too closely, but when you do "attempts = attempts++" that's not doing what you want it to do. To increment a variable, you just do "attempts++;" depending on how JavaScript handles types and stuff, you're probably doing something weird to the attempts variable. Basically you're saying "hey, Attempts, your new value is the fact that you've incremented yourself." Attempts is then like "lolwut?" "

test1 : for (var i = 0; i < 3; i++) {      //The first for statement is labeled "test1"    test2 : for (var j = 0; j < 3; j++) {   //The second for statement is labeled "test2"       if (i == 1 && j == 1) {          continue test1;       } else {          alert("i = " + i + ", j = " + j);       }    } }  /*Output is:       "i = 0, j = 0"       "i = 0, j = 1"       "i = 0, j = 2"       "i = 1, j = 0"       "i = 2, j = 0"       "i = 2, j = 1"       "i = 2, j = 2"       Notice how it skips both "i = 1, j = 1" and "i = 1, j = 2"*/

Also there's a random </td> in there; not sure if that has anything to do with anything, but I'm working on making a working version of the code you posted regardless. Be back in a few minutes!

 The problem is you're declaring the attempts variable inside of the validation function. Every time you click submit you're resetting attempts to zero.  Declare it outside of the function, and it should save the amount of times the user has attempted to submit invalid text.

I think I might have gotten it. It's pretty hobbled together, but it works...kind of. 

It's a bit too late for me to debug this but from looking at it there's a few things that should be changed. First, attempts should be attempts = 0. It's automatically declared when the page is loaded, so you're really limiting the user to two errors rather than three. Second, replace the while loops with if statements like this:
I can't get the spoiler warning to work so here's the code:

 function validate(){

var error = 0;

if (attempts => 3){

alert('Error Too many submissions');

}

else if (attempts  < 3){

if (username.length < 6){
alert('error');
error++;
}

if (password1 != password2){

alert('error')
error++;
}

if (error){

attempts++;
}
}
}

Hopefully you get the gist of what I'm saying. I'm a bit constrained on time right now so I can't write the code out completely.

I could barely handle Visual Basic so I'm sure I can help.

" You might try tested, I've seen threads there of people asking for help with code and getting some.  I don't know much Java, not enough to help anyways. "

This is what you want.

Crap! I just found the thread but its already been solved =/ Next time!
