Hi artsapimp,

Re:

Quote: If the textarea's name is Textarea then...

reminds of the man who said, "Doc, it hurts when I do this". To which the Doc said, "Don't do it"

Never use reserved words as either variables or their values; you will get away with it once in a while; the rest of the time, you will crash.

Regarding your radio code: Did you check the "Validating Forms" script/tutorial at my site? In it, I state that radio buttons are an array, and have to be treated with the following method:

function whatRadio(fldObj)
{
for (i=0;i< fldObj.length; i++)
if (fldObj[i].checked)
alert(fldObj[i].value)
}
....onClick="return whatRadio(this.form.NewOrReplacement)">New

Note I added an onClick to the second button

Let me show you what I don't understand. This does not work for me.

<?php
function whatRadio(){
    if(document.ManReq.NewOrReplacement.value == \"New\")
        {
        alert('Yes');
        return;
        }
        else
        {
        alert('No');
        }
}
...
<tr>
<td colspan=\"2\"><input type=\"Radio\" name=\"NewOrReplacement\" value=\"New\" onClick=\"return whatRadio()\">New</td>

<td colspan=\"2\"><input type=\"Radio\" name=\"NewOrReplacement\" value=\"Replacement\"><td>
</tr>
?>

This always alerts 'No'. How would I change this to work?

Try true false

Test for true or false for checkboxes and radio buttons.

No, that also works for me. I am wanting to know how to validate a Radio button, Textarea, Checkbox, etc.

If the textarea's name is Textarea then

document.theForm.Textarea.value == "" is always false. It is never == "" when I try to do it. The same is true for everything except Text boxes.

Is there something else that should be written for each of them?

Hi artsapimp,

the following works for me (nn4.7, ie6, & should for nn6):
[code]
<script language="javascript">
function isFormComplete(){
if(document.theForm.a.value == "")
{
alert('You must complete the Text Box');
return false;
}
}
</script>

[\code]

so, the question is what does your actual form look like? Insofar as validating all types of fields: see the "Validating Forms" script/tutorial at my site

That part of it is what I thought until I tried it with a textarea. The textarea never seems to equal "".

When I do if(document.theForm.Textarea.value = "") it always disregards the next steps as if it doesn't = "". What am I doing wrong there?

think of javascript as an onion...

And so to control elements on the page, you have to work your way down through the layers.

You can use generic terms and numbers to count down, or use the NAME attribute in the field elements to control it, so...

document.theForm.TextBox.value

would be

document.theForm.nameOfField.value

And whatever your checkbox, radio button, et cetera is named replaces nameOfField.
