Form Validation

[sanju]

Dear All,

i have 10 textboxes on a form, I require the following validation

1) if i fill the textbox in between(say 5th), then all textboxes
before that should be mandatory,ie Textboxes(1,2,3,4) should be
mandatory and rest of the textboxes should not be mandatory.

Kindly help me out..

Thanks in advance..
Regards,
Sanjay

Well, what did you try so far?

You should make a validationroutine that checks excactly that.
What is the problem?
Don't you know how to get the content of a textarea?
Don't you know how to implement the logic to check the former X
textelements for emptiness?
Please state your problem clearer.

"should be" or "have to be" ?

Have to be :

function validate(myForm) {
var Cl = [];
for(var i=0, L=myForm.length; i++)
if(myForm.type= 'text') Cl[Cl.length] = myForm;
if(Cl.length==10 && Cl[4].value!='') {
for(var i=0; i<5; i++)
if(Cl.value == '') {
alert('textfield : '+Cl.name+\nis empty !');
Cl.focus();
return false;
}
for(var i=5; i<Cl.length; i++) Cl.value=='';
}
else {
for(var i=5; i<Cl.length; i++)
if(Cl.value == '') {
alert('textfield : '+Cl.name+\nis empty !');
Cl.focus();
return false;
}
for(var i=0; i<5; i++) Cl.value=='';
}
return true;
}

<form onsubmit="return validate(this);" blah >

Dear Sam,

Thanks a lot for the code..
You have written this code by assuming that i filled 5th text box, but
i want to fill any textbox between 1 to 10 and the textboxes before
the filled one have to be mandatory.

What shud i do?
Thanks in advance

I do understand nothing at all
- you told about the 5th
- madatory = filled
- which one before ? how much before ?
- what about next fields ?

function verif(form, what) {
for(var i=0; i<form.length; i++)
if(form == what && form[i-1].value == '') {
alert('You missed textfield : '+form[i-1].name);
form[i-1].focus();
form[i-1].select();
}
}

<input onkeyup="verif(this.form, this);" blah >
<input onkeyup="verif(this.form, this);" blah >
<input onkeyup="verif(this.form, this);" blah >

What shud i do?

don't use that it's not very hepful for visitor

This might help you:

<html>
<head>
<title> Form validation </title>
<script type="text/javascript">
function checkInputs(form) {
var inputs = document.getElementsByTagName('input');
var notempty = false;
for (i = inputs.length - 1; i > -1; i--) {
if (inputs.type == 'text') {
if (inputs.value.split(' ').join('')) {
inputs.style.borderColor = '';
notempty = true;
continue;
}
if (notempty) {
inputs.style.borderColor = 'red';
} else {
inputs.style.borderColor = '';
}
}
}
return false;
}
</script>
</head>

<body>
<form onsubmit="return checkInputs(this.form)">
<input type="text"/>
<input type="text"/>
<input type="text"/>
<input type="text"/>
<input type="text"/>
<input type="submit" value="submit"/>
</form>
</body>
</html>
