Simple validation problem

[cody7]

<script type="text/javascript">
function CheckForm() {
var count = 0;
//Please place the code here
}
</script>


<form name="myform" onSubmit="return CheckForm()">



<input type="checkbox" value="red" name="check1" />red<br />
<input type="checkbox" value="green" name="check2" />green<br />
<input type="checkbox" value="blue" name="check3" />blue<br />
<input type="checkbox" value="yellow" name="check4" />yellow<br />
.....
<input type="checkbox" value="gray" name="check100" />gray<p>


<input type="checkbox" value="1" name="other1" />1<br />
<input type="checkbox" value="2" name="other2" />2<br />
<input type="checkbox" value="3" name="other3" />3<br />


<input type="submit" value="Submit">

</form>

 

 

Ok heres what i need. please complete the form validation on top.

But :

1. checkbox name must not change (it must be check1 up to check100  or more)

2. the validation MUST be some kind of a loop checking every checkbox if they are checked so that i dont have to write hundred lines of codes just to check each.

3. when a particular  checkbox is checked. count will increment. count++;

4. take note of the other 3 checkboxes, they must NOT be included in the validation. only checkbox having a word "check" on their names will be validated

 

<input type="checkbox" value="1" name="other1" />1<br />
<input type="checkbox" value="2" name="other2" />2<br />
<input type="checkbox" value="3" name="other3" />3<br />

 

5. at the end of the validation maybe we can put an alert() containing the value of count

 

 

 

Thank for any help

I don't know who you think "we" is, no one is going to write this code for you...

 

Basically, loop through all of the form elements, if it's a checkbox and starts with "check", increment a counter.

 

That's it.
