View Full Version : Stop cut and paste from textbox
07-11-2003, 01:08 PM
Does anybody know how to stop people cutting and pasting from a text box.
I have a page where I ask users to enter their email address twice - 2nd time to verify no typing mistakes. At the moment they can just cut and paste from one to the other. This makes the whole thing pointless so I would like to stop the ability to do this on the page.
Is it possible and how?
Thank you in advance.

Use a key event (onkeydown, onkeypress, onkeyup) and two counters. Then make sure the counters are both positive numbers before submitting (they won't be equal if the user types a backspace or delete). I'm fairly certain the paste will not increment the counters since it isn't a key event.

Thanks for that,
I may have to implement something like that if I can't find what I'm after. It will enable me to check that they didn't cut and paste the address, but what I was after was something that didn't let them do it at all.
I am sure (as sure as I can be) that once I went on a website which wouldn't allow me to highlight the text I had input into the box - so I couldn't copy it and had to re-type it.
That's what I am really after! But if it's not possible I think your suggestion is a workaround.
thanks for the help.

<input onselect="this.blur()" ...

Thanks, but that didn't work either. My text box code is like this..
<input type="text" name="address" size="25" maxlength="40" onselect="this.blur()">
and I can cut and paste using mouse or keyboard - even drag and drop!
Im using IE explorer 6 browser. Could this be part of the problem?

Let's see, let me count the ways to copy and paste (and this is only Windows!)
1) Ctrl + C | Ctrl + V
2) Ctrl + Ins | Shift + Ins
3) Right-click >> Copy | Right-click >> Paste
4) Select text | Ctrl-drag'n'drop
5) Edit >> Copy | Edit >> Paste
You can't directly prevent #5, and you can possibly do something about 1-4, but not without a lot of headache.
Personally, I don't think it's worth the effort.
If you MUST have a solution, then I can only offer this IE5+ fix
<input type="text" onpaste="event.returnValue=false" ondrop="event.returnValue=false"/>
However, you'll likely make people think you're site is busted and just piss them off. I don't recommend this, but there it is.
And, of course, Mozilla et al., Opera, etc won't be affected by this fix.

Thanks all for your help.
In the end Vladdy it did work - on IE 6.0.:thumbsup:
I won't even bother to check other browsers as the weekend is here.
But next week.......
