Preventing Paste of Text from IE's Filemenu

[2e1fmo]

Hi

I am trying to prevent a user from pasting text into a layer via the Filemenu system on IE via: Edit -> Paste

I have managed to prevent this using Ctrl + V by capturing the key events. And have prevented right clicking and pasting by using a dhtml right click script which replaces the menu.

With IE's filemenu I am able to perform an action when pasting occurs by adding:

onpaste="function();" to the layer tag

But i cannot prevent it from pasting. I thought that by adding:

return false;

to this function that it would cancel it but it still pastes the text. This is how i prevented the use of Ctrl+V.

Any help would be much appreciated

Thanks
Dan.

May be just open a new window without menu and close this window, and file menu would be off?
Good luck to you!

Use the onpaste event. Here is a function that I use to ensure pasted values match the expected data type.

// Use this function as the onpaste event handler for a field to ensure that the correct 
// data type is being pasted.  
function screenPaste(oField,sType) 
{ 
  event.returnValue=false; 
  var checkText=window.clipboardData.getData("Text"); 
  switch(sType) 
  { 
    case 'date': 
      if(isValidDate(checkText)) 
        oField.value=checkText 
      else 
        alert('Pasted value must be a valid date.'); 
      break; 
    case 'real': 
    case 'integer': 
      if(!isNaN(checkText)) 
        oField.value=checkText 
      else 
        alert('Pasted value must be a valid number') 
      break; 
    default: 
      break; 
  } 
  return; 
} 

An example of use would be:

<form> 
 <input type="text" name="SomeDate" onpaste="screenPaste(this,'date');"/> 
</form>

John K - thankyou very much for your help, the line : event.returnValue=false; is exactly what i was after to cancel the paste.

Thanks for both replies.
