preventing the pasting of text in forms

[odoisc]

situation : I have a website where users can make their own profile pages and this includes a guestbook. Now some of those users past pretyped messages in all those guestbooks to get some extra attention. This is becoming slightly annoying so I want to add something so that they really have to type their message instead of pasting it.

I dont know exactly what language I would need or how I should solve this, so every suggestion is welcome

Well this could at least help prevent those who paste by right-clicking:

use this

<div onbeforepaste="document.body.focus()"><textarea>adfhadfh</textarea></div>

it will be the best method for canceling paste

theres also these tags which you might want to take into concederation

onbforecut=""
onbforecopy=""
onbforepaste=""
oncut=""
oncopy=""
onpaste=""

hope that helps better than disabling right click, which disables much more functionality

These onbeforepaste/onbeforecut/... events; in which browsers do they work in? Are they IE5 (or 5.5) extensions perhaps? I guess it doesn't really matter much if they are, as you're blocking out 90pc+ of browsers from pasting anyway .

[Andrew-J2000]

heres all the event methods, some might be outta date

onabort = netscape 3, 4 - 4.7++, ie 4,5,5.5++
onafterprint = ie 5,5.5++
onafterupdate = ie 4,5,5.5++
onbeforecopy = ie 5,5.5++

onbeforecut = ie 5,5.5++
onbeforepaste = ie 5,5.5++
onbeforeprint = ie 5,5.5++
onbeforeunload= ie5,5.5++

onbeforeupate = ie 4,5,5.5++
onbounce = ie 4,5,5.5++
oncopy = ie 4,5,5.5++

oncut = ie 5,5.5++
ondataavailable=ie 4,5,5.5++
ondatasetchanged=ie 4,5,5.5++
ondatasetcomplete=ie 4,5,5.5++
ondragdrop = netscape 4 - 4.7++

ondragstart = ie 4,5,5.5++
onerror = netscape 4 - 4.7++, ie 4,5,5.5++
onerrorupdate = ie 4,5,5.5++
onfilterchange = ie 4,5,5.5++
onfinish = ie 4,5,5.5++

onhelp = ie 4,5,5.5++
onmove = netscape 4 - 4.7++
onpaste = ie 5,5.5++
onreadystatechange=ie 4,5,5.5++
onresize = netscape 4 - 4.7++, ie 4,5,5.5++

onrowenter = ie 4,5,5.5++
onrowexitr = ie 4,5,5.5++
onscroll = ie 4,5,5.5++
onselectstart = ie 4,5,5.5++
onstart = ie 4,5,5.5++

and i dont think i will be typing that out again lol

just about all events that don't look normal probably aren't. IE has many that don't work in other browsers

[Andrew-J2000]

hehe how about

onMaelstrom="alert('')"

Did I mention that I hate this kind of "disabling the user" stuff?

[Andrew-J2000]

Don't we all, no point moaning anymore, for every new web developer a similar question will come along like this.

Is there a complete quide to usability on sitepoint, coz that way every one ouldn't have to answer these usability problems

Some people have legit uses for disabling right click. And it is a good way to learn the error of there ways.

How about writing a function that strips all tags of that is if the textarea is a plain one and not the html versions.

Even if it's an html enhanced field only allow certain tags can still be accomplished.
