[Javascript] how can I check to see if a text box has a number or a string in it???

	I believe you need to include the document in your object reference, i.e.

	parent.TransDetail.document.myform.ClosingMonth.value

|Thanks Peter
|
|
|alert(parseInt(parent.TransDetail.myform.ClosingMonth.value));
|this gives me NaN
|
|
|both of these are not working...
|
|if( parseInt(parent.TransDetail.myform.ClosingMonth.value) == "NaN")
|        {
|            alert("You must select a Month");
|        return false;
|        }
|================== or ======================
|if( parseInt(parent.TransDetail.myform.ClosingMonth.value) == NaN)
|        {
|            alert("You must select a Month");
|        return false;
|        }
|
|this is not working
|
|what am I doing wrong?
