Disabling undo/redo in an HTML input field

问题

I am using asp.net input fields and they automatically provide undo/redo functionality. I am using JavaScript to format the value of the input field, however this ruins the undo/redo history.

• Is there a way to disable the undo/redo feature?

  or

• Is there a way to interact with the undo/redo history to add the correct values?

回答1:

Using JavaScript, try replacing the text field with a new one and then setting the value. New field, new undo buffer, right?

jQuery:

$('#theTextField').after('<textarea id="theTextField2"></textarea>').remove();
$('#theTextField2').attr('id','theTextField');
