Prevent User Using Ctrl V To Paste?
May 22, 2011I wish for my users to retype their email address instead of the copy and paste method to ensure they have typed it correctly both times.
How could this be done, would it be Javascript ?

Prevent The Ctrl+someKey Combinations?
Feb 3, 2011The code I will am including is far from finished, but some of what I do have works (the "submit" code does not work yet). I am able to prevent certain kinds of input including Shift-Ins pasting, but Ctrl-v pasting still works (and I do not want it to). Could you please tell/show me what code needs to be entered to my existing functions, or what new function I need to create (and call from my existing functions) to eliminate any kind of CtrlKey input?

Prevent Paste
Sep 29, 2007I found this handy little script on the net that means the user can only press backspace or numbers in form input.
<script type="text/javascript">
function numbersonly(e){
var unicode=e.charCode? e.charCode : e.keyCode
if (unicode!=8){ //if the key isn't the backspace key (which we should
allow)
if (unicode<48||unicode>57) //if not a number
return false //disable key press
}}
</script>
<form>
<input type="text" size=18 onkeypress="return numbersonly(event)">
</form>
It works, but it's not foolproof.
2 issues with this code.
1) Can I stop a user from accessing my website if he/she is not using
javascript?
2) Can I prevent a user from breaking the code and entering other
stuff by placing the cursor in the box and pressing ctrl+v (paste)
When The User Clicks Tab+ctrl To Go Back The Function That Is Called Is The Onblur Instead Of The Onkeypress?
Jul 17, 2009I'm creating a dynamic site but now I'm coming across a problem when I'm displaying input textbox.The textboxes uses two events onblur and onkeypressThese two events they invoke the same function which suppose to determine the function must be executed between Shownext() and tabbackorFront()When a use uses tab key to go or display the next select dropdown it functions well ut when the user clicks tab+ctrl to go back the function that is called is the onblur instead of the onkeypress.What I need is the way at which the events are called when tab+ctrl is clicked to go back

View 3 Replies View RelatedPrevent User From Modifying Browser URL?
Dec 12, 2010I own a game site and some users cheat by changing the browser URL. For example :
The URL for starting a game mission is this : ww.somesite.com/somethingaspx?htxm=18
And if they change the number to 87 they go to the end of he mission WITHOUT actually completing it.
They ONLY way to deal with this is by preventing users from changing the URL manually. Is there a way to do it? Like, if someone tries to change that number in the URL he gets a message and browser window closed(or something that will prevent him from going to that page)
Of course, the solution must not conflict with the normal navigation(which is the actual mission) which means the user should be able to navigate to different pages but NOT change the URL manually.
Prevent User From Entering Mistakes
Jul 3, 2009<script type = "text/javascript">
function testfield() {
var un = document.getElementById("dir").value;
if (!/^(/ftp/nas)/i.test(un)) {
alert ("Invalid starting characters - must be /ftp/nas");
return false;
[Code]...
I have a code like above which doesn't allow the user to proceed with out starting the field with a "/ftp/nas" which should be the starting of a path. Is there any way to make it disabled and the user only can enter the rest of the path. for eg: user1 has directory path like /ftp/nas/user1/help
so when this user enters his path, on the field "/ftp/nas" should always be available and the user has to only enter the rest of the path. and the user is allowed to enter only / (// is not allowed) and [A-Za-z] in the field. this is just to secure the application from typing mistakes.

JQuery :: Prevent User From Adding More Characters Into A Text?
Jul 2, 2009is there a way to prevent user from adding more characters into a text input based on a validation rule(eg. you entered more than n words, you can't enter more, but you can delete or edit)?

Or could I just set the cookie on a hyper link click event, and hope the client sets the cookie, before they are directed to another page.
JQuery :: Prevent The User From Submitting A Form Twice By Double Clicking On The Interface

This is what I have so far (it's just a start):
So, when I paste in a texarea right now there is an alert that says "paste". What I want is to get the data in the paste and then strip it to plain text - then paste it in the textarea.

View 4 Replies View RelatedDisabling CTRL-N In IE7
Apr 24, 2009I am using the following code for disabling Ctrl-N in IE7. It disables the Ctrl-N feature of IE which opens a new window containing the same page as the 'active' window. The code works great (at first glance). However, I noticed that, if you click anywhere inside the browser window and THEN press Ctrl-N, the new window will open. If you don't click anywhere inside the window, the following code works. Can anyone see an improvement to the following code so that clicking inside the browser window doesn't bypass the javascript?
