javascript help

[leena]

Hello Everyone!

I know this is a php forum, but I have tried posting messages on javascript forums, and have not gotten responses. I know this is a good forum, so I thought someone here might be able to help me.

I have a form set up, and I had to use an array for some of the form values. Those form values in the array are required.

For example:
playerArray[0]=brown; // hair color
playerArray[1]=green; // eye color
playerArray[2]=18; // player age
playerArray[3]=5; // skill level

Each one of those spots in the array are required so I need to have a javascript to check to make sure all those spots are filled in before they submit the form.

I know how to use javascript to check for required fields using normal field names, however, when it goes into an array, I am not sure how exactly to run through the array and make sure each spot in the array has a value.

I was thinking something along these lines:

for (var i = 0; i < formName.myArray.length; i++) {
if (formName.myArray.value == ""){
return false;
}
}

Can someone give me some hits, or point me in the right direction?

Thanks for your time! Any response is greatly appreciated.

are you saying the field names of the form is an array?

i have trouble passing array names to javascript. i usually have to make a hidden field of some sort.. for example:

<script language=javascript>
function validate(){
  if(document.player_0.value=''){
    return false;
  }elseif{
    document.player_1.value=''){
    return false;
  }

  return true;
}
</script>
<form name=f method=post action=foo.php>
<input type=hidden name=player_0>
<input type=text name=player[0]  onchange="document.f.player_0.value=this.value;"><br>
<input type=hidden name=player_1>
<input type=text name=player[1] onchange="document.f.player_1.value=this.value;"><br>
<input type=submit onclick="return validate();">
</form>

not sure if that's what you're talking about, and that code is not tested either.

good luck

Yes, the field names of the form is an array.

I has to be an array because of how dynamic the forms must be.

The problem with using actual names is that I don't know how many fields will be attached to this form.

Thanks for your reply. 🙂
