ASP and JavaScript (Passing parameter)

[F159753]

Hello,

I have a form includes one text box named "Date", one Submit botton named " Add Item" which will submit the form and open other form.

there is onemore button named " Add Mileage" which by pushing that, I would like to check if the text box named " Date" is empty or not and in both case will open other window and depends if the text box is empty or not, shows different messages in new window open up.

Please please please let me know if you have any solution.

Best Regards,
Faranak

If you are going to submit the form either way and open a new window either way, you probably one need 1 button right? If you are talking about alert boxes like a validation of a form before submission, then yes you will need to use javascript or client side vbscript.

A perfect example of this can be found here
http://www.w3schools.com/js/js_form_validation.asp

If you are going to submit the form though you can just use ASP to check the value

dim UserDate
UserDate = request.form("txtDate")
if UserDate = "" then
     'determine message string
else
     'they entered the date
end if

Thanks for your reponse, but It is not clear to me yet. Here is my code:



<form name="Formd" action="ContractorExpenseAddItem.asp" method="post" >

<input name="WeekEndingDate" ID="WeekEndingDate" type="text">


<td colspan="1" valign="top"><span class="text"><input type="submit" value="Add Item >"> </span></td>


<td colspan="1" valign="top" width="200"><input type="button" onClick=window.open('ContractorExpenseAddMileage.a sp?IID=<%=A%>','AddMileageWindow','width=600,heigh t=250,toolbar=yes,location=yes,directories=yes,sta tus=yes,scrollbars=yes,copyhistory=yes,resizable=y es') value="Add Mileage >"></td>

</form>

As you see, by Submitting "Add Item" in form action I am submitting the form and opening other form.
My problem is with other button named " Add Mileage" when I click on the button I want to validate the text box first then open other window so basically my form is not submitting so I can't request.form the text box value!!!!!

What should I do? :(

Well it all depends on what you require of the behavior of the app.

You can't have it both ways. You either need to validate the form prior to submission, (i.e don't let them submit unless the form is correct) or you need to go ahead and let them submit the form, and do your checking on the other side with the request.form like above.

Either way you really only need 1 button. Then you just need to call your validating javascript from the onsubmit event of the form, like was displayed in the above example link.

<script type="text/javascript">
function validate_required(field,alerttxt)
{
with (field)
{
if (value==null||value=="")
  {alert(alerttxt);return false;}
else {return true}
}
}function validate_form(thisform)
{
with (thisform)
{
if (validate_required(email,"Email must be filled out!")==false)
  {email.focus();return false;}
}
}
</script>
 

<form action="nextwindow.asp"
onsubmit="return validate_form(this)"
method="post">
 

I guess if this still doesn't answer your question please provide more info on exactly what you are trying to accomplish. Are you trying to do a calculation for the user before he proceeds to the final window? Or are you trying to actually do a validation before the user submits?

Again I must say that if you are wanting them to submit the form either way then just use your request.form method on the next page to check the value and display your messages then.

I do think I see what you are trying to do. You are trying to bring up a popup window with information on it if they submit the form a certain way (with the value entered)? If so you can just do a pop up window on the body onload event on the ContractorExpenseAddItem.asp page, that will get its info from the request.form data.

All kind of guesses though since I'm not sure what your final goal is here.

Thanks a bunch.

how should I complete the following code:

onClick="javascript:window.open('abc.asp'

if I want to send a parameter with it without submitting the form?

It should be something like the following line, but it is not right!!!

onClick="javascript:window.open( 'ContractorExpenseAddMileage.asp?A=) + escape(document.theForm.userName.value)"

Thanks
