"Object Expected" Error

[Coder7]

Good afternoon.

I have editible input = text and I need to validate that txtCommentText is not null or spaces and I'm using the javascript below. I get "object expected" both when I blank out the text and when I leave it unedited during form submission. The alert statement below is returning a screen display that contains the correct values for the text box contents. The line that is highlighted in debug regarding "object expected" is: if ((lAction=="E&quot && (isWhiteSpace(document.frmCommentsAVED.txtCommentText.value))).

I would appreciate any insight that you can provide. Thank you very much.

------------------------------------


function ValidateFields()
{
// To check if Comment Text field is blank in Edit function.

alert(" txtCommentText value = " + document.frmCommentsAVED.txtCommentText.value ) ;
if ((lAction=="E&quot && (isWhiteSpace(document.frmCommentsAVED.txtCommentText.value)))
{
alert("The comment text field cannot be blank.&quot ;
document.frmCommentsAVED.txtCommentText.focus() ;
return false ;
}
else
{
document.frmCommentsAVED.sAction.value = lAction+"SAVE" ;
return true ;
}
}

You need to tell your script what lAction is. As it stands, it's undefined in your function.

Just a suggestion... if you're checking for an input filed that is blank, just test it's length. If it's zero, than the field is empty!

if (document.frmCommentsAVED.txtCommentText.value.length == 0) There's always a better way...

I do that at the very beginning of my javascript. Sorry that I didn't include all of the javascript code - here it is now. Also I added an alert to confirm that lAction =="E" and is is.

Again, thanks for any insight.

isWhiteSpace is a Java function, not a Javascript function. Hence the error &quot;Object expected&quot; There's always a better way...

I think I have a syntactical error someplace in my javascript. isWhiteSpace is a javascript function that I use in other code and it works fine. Also, isWhiteSpace is a standard in our shop so I have to use it.

This syntax stuff will drive you crazy!!

Thanks for your input.

In my project I was missing the javascript file that contained the isWhiteSpace function.

I wanted to post this in case someone (another newbie!!) has something similar come up.

Was a good lesson.

Thanks tviman, you've been great!!!!
