Problem with validation…

Copy linkTweet thisAlerts:
Sep 29.2004

This works:
if((form.abc.checked == true) && (form.abcaccess.value == “”)) {
alert(“nError!rnblah, blah”)
form.abcaccess.focus();
return false;
}

But this doesn’t:
if((form.name.checked == true) && (form.lname.value != true || form.middle.value != true || form.phone.value != true)) {
alert(“nError!rnblah, blah, blah.”)
form.name.focus();
return false;
}

Anytime I get past trying to validate more than two fields, it breaks.
What I want is to say if box 1 is checked, and box 2, 3 or 4 are not checked, error.

Thanks…

@sciguyryanSep 29.2004 — Are the other items (Besides the first one) textboxes or textbased elements?

If not try:

<i>
</i>&lt;script type="text/javascript"&gt;
&lt;!--
if ((form.name.checked == true) &amp;&amp; (!form.lname.checked || !form.middle.value || !form.phone.value)){
window.alert("nError!rnblah, blah, blah.");
form.name.focus();
return false;
}
//--&gt;
&lt;/script&gt;



If not, can you please exaplin exactly what you want to do?

Try this:

<HTML>

<Head>

<Script Language=JavaScript>

function validate(isForm){

count = 0;
nElements = isForm.length;
if (isForm.boxName[0].checked == true)
{
for (n=0; n<nElements; n++)
{
if (isForm[n].type = 'checkbox')
{
if (isForm.boxName[n].checked == true){count++}
}
}
}
else {alert('Box 1 was not checked')}
if (count == 1){alert('Only the first box was checked')}
if (count > 1){alert('Okay')}
count = 0;
}

</Script>

</Head>

<Body>

<form name="boxGroup">

<input type="checkbox" name="boxName" value=1>First<BR>
