On checking a field against validations, if validation fails , a pop up window

  • 0

On checking a field against validations, if validation fails , a pop up window is opened.Now when i close the pop up the pop up should return the focus to the last element(in case more than one validation fails for more than one text field). any suggestions ?
My code is:-

 function submitformFinal(frm) {
 var message;


 var inputs = frm.getElementsByTagName("input");

     for (var i=0; i < inputs.length; i++)
     {
         if (inputs[i].getAttribute('type') == 'text')
         {

             if(!checkSpecialChars(inputs[i].value))
             {
                  message =  " Special characters found in element = '";
                  message += inputs[i].getAttribute('name') + "'\n";
                  // alert(message);
                  // createPopup(message);

                  MyPopUpWin(message);
             }
        }
    }    
    // return true;
 }

function checkSpecialChars(fileOnlyName)
{
    if ((/[^a-z0-9\.]/gi).test(fileOnlyName)) {

        return false;
    }
    return true;
}

function MyPopUpWin(message) {
    var iMyWidth;
    var iMyHeight;
    //half the screen width minus half the new window width (plus 5 pixel borders).
    iMyWidth = (window.screen.width/2) - (75 + 10);
    //half the screen height minus half the new window height (plus title and status bars).
    iMyHeight = (window.screen.height/2) - (100 + 50);
    //Open the window.
    var generator = window.open();
    document.onclick=function()   {
        try{
            generator.focus();
            return false
        }
        catch(e){}
    }

    generator.document.write('<html><head><title>Pop uP</title>');
    generator.document.write('<p style="color:#C52B27;">');
    generator.document.write(message);
    generator.document.write('</p>');
    generator.document.write('</head><body>');

    generator.document.write('<a href="javascript:self.close()"><img src="/img/save_orange.gif" border=0">  <\/a>');
   generator.document.write('</body></html>');
   generator.document.close();
}

    In your code, use:

    MyPopUpWin(message); <- existing line
inputs[i].focus()
