javaScript confirm and PhP

[leon_zilber]

Hi guys,

I have the following logic:

echo "<input type=submit name=addsubmit value=Add onClick=javascript:lastCheck()><td>\n"

javascript lastCheck() just pops-up a Confirmation dialog wit Ok/Cancel buttons.

If a user Press Cancel, I want use to stay on the same page, and if Ok was press, submit should work.

Right, when either button is pushed, submit is pefrormed. Does anyone know how can stay on the same if Cancel button was chosen?

Thank you!

You don't need PHP.

<script language="JavaScript">
function lastCheck() {
if (confirm("Are you sure you want to submit this form?") )
{
return true;
}
else
{
alert("Survey has not been submitted!");
return false;
}
}
</script>

Unfortunatelly, still if Ok/Cancel buttons are presses, submit is performed.

Adam,

This page is a PhP-based page, and I need to add this JavaScript functionality.

echo "<table cellpadding=3 cellspacing=0 border=0>\n" .
"<tr><td><input type=submit name=addsubmit value=Add onClick=javascript:lastCheck()><td>\n" .

Thank you.

change the input type to BUTTON (or image), this way by default when the button is pressed nothing happens.

using javascript if lastCheck evaluates to true then use javascript to submit the page.

ie:
document.form_name.addsubmit.submit();

or...leave the button as a submit button and change your initial form tag to include:

on Submit="return lastCheck()"

if lastCheck() returns false, the form won't be submitted.

[sethadam1]

the code needs to be called in the form tag, ie

<form action=whatever method=post onSubmit=lastCheck()>

rather than onClick. An onClick event will call a script as the button is clicked but not effect the action, but the the onSubmit function call will run as the form is submitted and control the action.

Hi guys,

Thank you for your replies. Unfortunately, when I use onSubmit, lastCheck() is not even called. confirm dialog doesn't even popups....

Any ideas why?

Thanks again!

is your submit button type "submit"?
