Disable Backspace Key

I'm trying to figure out how to disable the backspace key on
an input form. Or, I need to figure out why I can't type into an
input field after I've backspaced(erased) all the
characters?

Hmmm... I've not seen where you can't type after deleting all
the
characters. Do you maybe have the input set to multiline and
have the top
line blocked or something? I don't know that there's an easy
way to disable
Backspace for an input field.

Disable backspace key as 'go back'

Does anyone know a way to prevent the backspace key from acting like a shortcut for "Go back"?
I never, ever use backspace for that function. The only times I go to the previous webpage by pressing the backspace key are unintentional and often cause loss of information on dynamic webpages.
I believe that making the backspace key act as both a text editing tool and a history navigation shortcut, based solely on whether the cursor is inside a text field or not, is a serious design flaw. I may be mistaken but I believe this behaviour was copied from Internet Explorer. Why on earth did Apple copy a design flaw from the most flawed browser in the world?
So, kudos to anyone who knows a Safari equivalent of setting "browser.backspace_action 2" in Firefox.

Hi Derek,
This feature is sufficiently annoying to make we want to change browsers until Apple fixes it.

Everyone here on the forum is just a fellow user like yourself. I'm not aware of a way to override it, but maybe someone else will chime in.

How can I disable 'backspace' key from navigating back a page?

Several times over the last couple weeks, I type up a very well thought out response on Facebook in political conversations with friends. An hour or two into my work, I hit backspace with the intent of editing what I wrote (maybe after I scrolled or something, so maybe I unintentionally took the edit window out of focus). The navigator takes me back a page and I lose my two hours of work. Infuriating! Shortcuts with the ability to wipe out two hours of works should be disable-able. Not only that, I feel that is an unsafe shortcut for this very reason, and would have added a SHIFT modifier key or something like that. I think I invented a cool word: disable-able.

You can set the Integer pref <b>browser.backspace_action</b> to <i>2</i> on the <b>about:config</b> page to disable the backspace action. BTW Shift + Backspace does the reverse: going Forward if possible, so that is taken as well.

Backspace key disable

this is sort of a javascript question, but its on my jsp pages so i'll ask. ;)
I would like to be able to disable the backspace key so that
a user cannot hit it to travel back a page. However, i want to leave
it enabled so that they can at least backspace while in form text elements and text areas, etc.
i have this bit of code (see bottom) that will capture the backspace, but it turns it off even for the text elements in a form.
the good news is that its for an intranet application and we are only going to be supporting IE 5.5 or better, so it doesn't have to be cross browser compatible
thanks,
ken
<script language="JavaScript"></script>

There are two ways to approach this, and neither are very elegant, though they both should work in i.e. (other browsers will presumably have an analogous method for accomplishing them). Firstly, you could use a client script to populate the onblur and onfocus properties of all your forms on the client page. Something like
for(var i = 0; i < document.forms.lenth; i++) {
    document.forms.item(i).onfocus = "inform=true";
    document.forms.item(i).onblur = "inform=false";
}This means that you could leave your forms the way they are. Note that the forms collection of the document is an i.e. only thing. Alternatively, and this is the preferred method, you could simply ask the even which object fired it and evaluate whether or not to cancel the event using an if statement. Again, in i.e. only, every event has the srcElement property which is the object that fired the even. In the case of a keydown event, the object that fires the event is whatever is selected when you press the key. Specifically, if the backspace key is pressed in a text field or textbox etc. it will tell you if you ask. Something like
document.onkeydown = keyCatcher
function keyCatcher() {
    var e = event.type;
    if(event.keyCode==8 && e != "text" && e !="password" && e !="textarea" ) {
        event.cancelBubble = true;
        event.returnValue = false;
}You'll notice that the previous method is by far the fastest as it only has 3 compisons, as opposed to the many required for sorting through all of the form and input elements. Also you need no global variables.
Lastly you could check to see if an input tag is the activeElement when the backspace key is pressed and if one is, block it. Something like
document.onkeydown = keyCatcher
function keyCatcher() {
    if(event.keyCode==8 ) {
        for(var i = 0; i < document.tags("input").lenth; i++) {
            if(document.tags("input").item(i) == document.activeElement) {
                event.cancelBubble = true;
                event.returnValue = false;
}Again, both the tags collection and the activeElement property are I.E. only things. For other browsers I assume you would need some kind of detection script and some options (or just don't block they're backspace keys). Also, I haven't tested any of this code, but you get the idea.

Disable Backspace when in input text fields

Im trying to find a way to disable the keyboard backspace
button from going back a page in the site but allowing it to
function as a character delete when needed for typing in an input
text field of a form.
Strangely this problem only occurs for about a minute after
the page is opened....after that it then works correctly. You can
see what I mean by accessing the site's contact page
www.safetybusiness.co.uk
I have found two different sets of code to disable the
Backspace completely, but this then means it doesn't work at all
when wanting to delete in the text field.
Method 1:
<script type="text/javascript">
if (typeof window.event != 'undefined')
document.onkeydown = function()
if (event.srcElement.tagName.toUpperCase() != 'INPUT')
return (event.keyCode != 8);
else
document.onkeypress = function(e)
if (e.target.nodeName.toUpperCase() != 'INPUT')
return (e.keyCode != 8);
</script>
Method 2:
<script>
function checkShortcut()
if(event.keyCode==8 || event.keyCode==13)
return false;
</script>
<body onkeydown="return checkShortcut()">
Anyone know how I can overcome this?

The TextField class has a tab order property. You may want to
look into this. As for disabling the backspace key, you can grab
key presses from user input. I'm not 100% on this but you could use
Flash to test the key being pressed. If backspace is pressed, find
out the current object with focus (unsure of this part), if it's an
input box in flash, have flash handle it or if a text box doesn't
have focus, send it out to javascript to have it handle it.

How to tackle BACKSPACE key behaviour?

Disable backspace in dgv combobox

I would like to disable backspace and delete in a combo box in a dgv
I used the following
Private Sub frmWorkSelectionPopupAll_KeyDown(sender As Object, e As KeyEventArgs) Handles MyBase.KeyDown
If e.KeyCode = Keys.Delete And e.KeyCode = Keys.Back Then
e.Handled = True
End If
End Sub
Delete is disabled, backspace is not.
I have set the form KeyPreview to True.
Can you please suggest something?
John

The options for DisplayStyle are "ComboBox", "DropDownButton" and "Nothing". No luck with any of the 3.
Are you referring to something else?
I tried to replicate the issue by creating an app with a DataGridView and three columns. However I could not EDIT in the ComboBox column anything without using a special Sub routine to do that.
Nothing I tried would let me use the keyboard or mouse to do anything in the ComboBox. Except for using Edit Mode and AutoComplete in which AutoComplete is unecessary in your situation I would imagine. Then I could type a letter while over the ComboBox
and I suppose if something in the ComboBox's list matched it would display. But even then I couldn't backspace or anything else or actually alter text displayed by the ComboBox.
And I believe from this link
Problem with combobox and databound datagridview that this statement is entirely accurate "The ComboBox used by the DataGridViewComboBoxColumn has a DropDownStyle property set to ComboBoxStyle.DropDownList, but DataGridViewComboBoxColumn does
not expose this property, so out-of-box there is no way to type text into a combobox column."
However at that link is code supplied which can not only provide the ability to edit text in a ComboBox in the ComboBox column but actually add new items to the ComboBox list (or alter it to remove items, whatever) which I used in the below code the Sub
that allows editing text in a ComboBox in a ComboBox column. So unless you are doing something along those lines I really don't know why you are having an issue. Nobody should be able to alter anything in the ComboBox's in the ComboBox column using the keyboard.
Public Class Form1
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
DataGridView1.EditMode = DataGridViewEditMode.EditOnEnter
DataGridView1.ColumnCount = 3
DataGridView1.Columns(0).Name = "Product ID"
DataGridView1.Columns(1).Name = "Product Name"
DataGridView1.Columns(2).Name = "Product Price"
Dim row As String() = New String() {"1", "Product 1", "1000"}
DataGridView1.Rows.Add(row)
row = New String() {"2", "Product 2", "2000"}
DataGridView1.Rows.Add(row)
row = New String() {"3", "Product 3", "3000"}
DataGridView1.Rows.Add(row)
row = New String() {"4", "Product 4", "4000"}
DataGridView1.Rows.Add(row)
Dim cmb As New DataGridViewComboBoxColumn()
cmb.DisplayStyle = DataGridViewComboBoxDisplayStyle.DropDownButton
cmb.FlatStyle = FlatStyle.Flat
cmb.AutoComplete = True
cmb.HeaderText = "Select Data"
cmb.Name = "cmb"
cmb.MaxDropDownItems = 4
cmb.Items.Add("Hello")
cmb.Items.Add("Goodbye")
cmb.Items.Add("Seriously?")
cmb.Items.Add("Not")
DataGridView1.Columns.Add(cmb)
End Sub
Private Sub DataGridView1_EditingControlShowing(sender As Object, e As System.Windows.Forms.DataGridViewEditingControlShowingEventArgs) Handles DataGridView1.EditingControlShowing
'Allow user to enter new values for ALL DataGridViewComboBox controls in the DataGridView
If (TypeOf e.Control Is DataGridViewComboBoxEditingControl) Then
Dim cmb As DataGridViewComboBoxEditingControl = CType(e.Control, DataGridViewComboBoxEditingControl)
If Not cmb Is Nothing Then

My Keyboard and the Delete/Backspace Key

So last night I was looking through my system settings and making small tweaks here and there where I wanted them. It was a nice little experience. However, I somehow disabled my delete(backspace) key completely. Also other keys like my shift key are suddenly sticking. I have gone back in and tried to restore everything back to factory settings on my keyboard and still nothing. Am I missing something or is there somewhere else I should be looking to fix this besides going into System Preferences>Keyboard and Mouse>???? I am so confused I do not know what I did.

Am I missing something or is there somewhere else I should be looking to fix this besides going into System Preferences>Keyboard and Mouse
Yes. "Shift key sticking" sounds like 'Sticky Keys' - check in System Preferences > Universal Access > Keyboard.

I need some assistance on stopping my backspace key from "sticking" on my iPad 2?

I have reset, restored, and rebooted. Nothing is working. My backspace key goes rogue even if I only hit it once. I've had this pad for 3 days and I'm a bit frustrated. I've noticed that the backspace key goes haywire in almost all third party apps but it also happens when I type email, calendar , events, and notes. The only way I can stop this from happening is to hit the spacebar multiple times or any other key on board. I am not new to Apple products as I have had several iPhones, iPod touches, and I had a Mac Book Pro for work. I have searched the communities and saw that this was an issue with earlier iPhones but I have not read anything to iPad 2. Any helpful assistance you can provide is appreciated.

I assume that you know if you hold down on the delete/back space key that it picks up speed and will rapidly delete sections of text as opposed to one letter at a time.
If you have restarted and reset (hold down the sleep and home buttons until the Apple logo appears) and have had no success, I can only suggest closing apps. Go to the home screen and double tap the home button to bring up your recent apps at the bottom. Tap and hold down on any app icon until they all wiggle. Tap the minus signs on the apps to close them. Close every app in the task bar. Tap the screen above the task bar and then restart the iPad.
I have no idea if this will help, but it can't hurt to try it. If your iPad is only three days old, I would also suggest a call to technical support. You get 90 days of phone support when you buy an iPad.

How can I disable a key through software?

A friend of mine spilt water on her keyboard. As a result, her forward slash key frequently spams and makes typing difficult. I used a program to remap the forward slash key to a forward delete key, but that has also caused problems. What I'm looking for is a program that will allow me to completely disable a key.
I should note, I've used KeyRemap4Macbook and I've also developed my own code, which disables the key on Cocoa applications. However, the key still spams on applications like Microsoft Word.
Her Macbook is more than a year old, and she can't afford to buy a new one.
Any suggestions?

Liquid in a physical keyboard is great trouble. You may worsen state if you continue to use it like this, make the effort to change it. It is not cheap, but may prove cheaper than damage the whole computer.

Loose backspace key

Hi, this seems to be my fourth or fifth problem with my MacBook (I hope there aren't any more) but my backspace key seems to be worryingly loose. Is this the same on every MacBook?

No. Have it looked at if it's in warranty. The keyboard may need to be replaced.
If you've had a lot of problems with your MacBook (three or more repairs), call Apple Customer Relations and see if you can get the computer replaced. I got mine replaced after three repairs.

Rebinding Backspace Key

Is there anyway to rebind the backspace key so that it does something else other than what it is supposed to do (i.e. delete the character before the current carat position). I've tried doing the inputMap()/actionMap() method to rebind and it fails to stop backspace from deleting the character before the current carat position.

A much easier way of not deleting is to use a custom Document, but I assumed you wanted delete to still work correctly. I found [url http://forum.java.sun.com/thread.jsp?forum=31&thread=304562]this and tried it and it worked. I have no idea why.import java.awt.*;

Backspace key doesn't work during install

I'm installing Oracle 10.2.0 under Solaris 10 05/08 I'm using PuTTY 0.6.0 and Cygwin as my X server. In the Oracle install windows, my backspace and delete keys do not work. They work fine everywhere else.

hi jnojr
what about making executing the following command in your shell before starting the runInstaller:
stty erase <backspace key>
stty delete <delete key>
please read that document: http://www.acm.uiuc.edu/workshops/cool_unix/stty.html
Read that also:
http://www.linuxdocs.org/HOWTOs/Keyboard-and-Console-HOWTO-5.html
check your settings
#stty -a
What is the result of that command?
If the issue is only on x11 then try that:
Backspace key to generate a BackSpace:
% xmodmap -e "keycode 22 = BackSpace"
Delete key to generate a Delete:
% xmodmap -e "keycode 107 = Delete"
this should fix your issue.

Backspace Key stopped working normally on Macbook Pro

Hello,
I was able to use my backspace/return key totally fine by just pressing it and it would go back a space. One day i start my laptop up and i am not able to go back anymore, absolutely nothing happens when i press my backspace key, i now have to press fn+backspace in order to use the normal backspace option of deleting one letter or several letters that i have just typed. It doesn't seem to be a hardware issue as the backpace is now fn+backspace, how do i get it to go back to normal as it is tres annoying to press two keys for this? Any help is much appreciated.

Create another user account on the computer and see if it behaves the same way. If it does then it's probably a hardware issue, if it doesn't then it's software and most likely a setting that has changed.
