How to stop further JavaScript events from executing

Question

I'm using an Infragistics grid on a form and am handling multiple client-side events on the cells (eg cell click, before cell edit, before cell update, etc).

On the cell click event, I'm spawning a secondary window (successfully) as follows:

 var convChartWindow = window.open("conversioncharts/" + currentCell.getValue() + ".html", "chart", "location=0,0, status=1, scrollbars=1, width=" + screen.width + ", height=175");        
 convChartWindow.focus();

However, the 'convChartWindow' does not maintain the focus, and gets covered with the parent window. None of my other cell events fire after this, but there seems to be some Infragistics JavaScript that runs.

Is there a something I can put after the .focus() above to prevent further javascript from running and keep the focus on the correct window?

Thanks!

Call this:

// Prevents event bubble up or any usage after this is called.
// pE - event object
function StopEvent(pE)
{
   if (!pE)
     if (window.event)
       pE = window.event;
     else
       return;
  if (pE.cancelBubble != null)
     pE.cancelBubble = true;
  if (pE.stopPropagation)
     pE.stopPropagation();
  if (pE.preventDefault)
     pE.preventDefault();
  if (window.event)
     pE.returnValue = false;
  if (pE.cancel != null)
     pE.cancel = true;
}  // StopEvent

i dont know what infragistics is. ill assume its some framework over which you have no control. if i were you i would try the following:

1) set a timeout to take focus back to the window after 1000 ms, or set a timeout loop to set focus to the window you need. this is a hack.

2) figure out what functions fire the events that ruin your life, override those functions in your code and add a flag that will prevent them from doing something evil

3) last, atleast read this: http://www.quirksmode.org/js/events_order.html there might be something useful for you in there

让子窗口在焦点打开时自动调用焦点。

Answer 4

If there is something else in the function that runs the code you gave, try using:

break;

after:

convChartWindow.focus();
