Displaying Errors In Popup Windiws

durahman

I am building a dynamic page which handle form. I wanted to remind user if they miss a required field by issuing a message. At the moment the message is displayed on the same page as the form.

Can the message be displayed in s popup windows instead? How do I do this.

Why is it a problem to display the error message together with the form? Seems like a good idea to me. Popups are blocked by most browsers today anyway.

However, if you really want to do it, validate your form before sending any HTML to the browser (well, the body tag anyway.) In the body tag call a JAVASCRIPT function that I've included to show the errors (I'll let you figure out the rest.)

function errorWindow(message,pageWidth,pageHeight) {
	newWindow = window.open("","newWindow","width="+pageWidth+",height="+pageHeight+",left=50,top=50,status=yes");
	newWindow.document.open();
	newWindow.document.write('<HTML><TITLE>Errors</TITLE>');
	newWindow.document.write('<BODY bgcolor="#FFFFFF" LEFTMARGIN="0" TOPMARGIN="0" MARGINHEIGHT="0" MARGINWIDTH="0" onBlur="self.close()">'); 
	newWindow.document.write(message);
	newWindow.document.write('</BODY></HTML>');
	newWindow.document.close();
	newWindow.focus();
}

Or...dynamically create a layer that sits over the form and write the error messages in it. Provide a link or button to hide the layer.

Thanks. Just want to know other alternative.
