How To Disable Backspace For Text
Jul 16, 2010<script language="javascript">
function disableback(evt) {
if (evt.keyCode == 8 || evt.which == 8) {
return false; /*have also tried return (evt.keyCode != 8) and evt.which == 46 and the variations*/
}}
</script>
<input type="text" onkeydown="disableback(event)" onkeypress="disableback(event)">
I am doing my testing on Firefox. From posts this should work to stop from the page going back yet no dice. I currently have the text area in a frame and have it reload keeping all text in a variable, it just seems awful sloppy.
This may work on IE, have yet to test. Just trying for FF atm.
Disable Backspace On Form Pages
May 6, 2004I've been getting some complaints from my users: when filling out forms, while on a select box, pressing the backspace key would actually mimick pressing the back button (like history.go(-1) ...)
Then I realized that if the user wasn't in a textbox or a textarea, pressing the backspace key would send them back one page. Now I've got a multi-page form in an iFrame and that's really screwing their inputs up as it loses all the information entered in that form (pressing back doesn't submit/post backwards... I wish it would!).
So anyway, here's the script I'm using on all my pages so that the user won't 'accidentally' go back a page. (In my opinion, with my users anyway, a user shouldn't need to hit the backspace unless they're in a textbox or a textarea).
//so backspace doesn't go back
document.onkeydown = checkForBackspace;
function checkForBackspace() {
//we can backspace in a textbox
if(window.event.srcElement.type.match("text")) {
return true;
}
if(window.event && window.event.keyCode == 8) {
// try to cancel the backspace
window.event.cancelBubble = true;
window.event.returnValue = false;
return false;
}
}
This is IE only. srcElement is an IE thing.. I believe most other browsers use target. I don't know what else would be different, but anyway, that's what I'm using.
BTW: If you're wondering why anyone would press backspace in a selectbox, well I recently showed them that you can press the first letter of an item in the list to quickly jump to that item. Well, perhaps naturally, if they press the wrong key, instead of pressing the right key, they try to hit backspace first. Just if you were curious... I guess checkboxes and radios could be similar?

Dec 14, 2005Im trying to find a way to disable the keyboard backspace button from going back a page but allowing it to go back a character.
The problem happens with our webmail client when composing a message, if the cursor is not in the textarea and backspace is clicked it goes back a page and everything typed in the textarea is lost, its easy to do because we use a cms menu thats always active, and distract the cursor, and its very frustrating.

How To Allow CARRIAGE RETURN And BACKSPACE?
May 22, 2007This JS limits the input characters into the form. How do I modify it
so that it also allows CARRIAGE RETURN and BACKSPACE (for making text
correction)?
Due to the template engine I am using, I cannot use IF/ELSE statement.
<form>
<textarea name="event_description" ONKEYPRESS="if (document.layers)
var c = event.which;

View 2 Replies View RelatedJQuery :: Preventing The Backspace Key Event From Firing?
Jun 22, 2011I have a form element that is readonly. <input type="text" id="kfs_acct_1" readonly="false" /> This field is dynamically populated an making it readonly prevents users from changing the value in this field. The problem I have is users click on the field and try to delete it's value. They click in the field and hit their Backspace key. This takes them away from the page to the page from whence they came. Because of the way the form is set up, doing this makes them loose all the data in the form (the one with the readonly box). How can I prevent the Backspace key from fireing and taking the user away from this page? I've tried a few things, but apparently making a field readonly keeps some key events from being seen.

Jquery :: Link Focus Lost In FF 3.5.5 When Following Link And Hitting Backspace Key?
Nov 10, 2009I'm using Firefox 3.5.5 on Vista 32 Home Premium SP2 and only recently noticed that (javascript/jquery being enabled) link focus is lost when you tab through a page, follow the link to another page and then hit the backspace key to come back. Tab navigation continues at top of page, not with the next link after the one in focus before.
No problems in this respect with IE8 and Opera. As soon as you disable javascript with noscript, the problem disappears and link focus stays, so that tabbing brings on the next link instead of starting on top of page again.
Just confirmed it on jquery/com (following navigation link to Plugins and hitting backspace) and on learningjquery/com (navigation links). A Google search didn't yield any answers nor even any similar reports on this particular problem.
It's even more irksome in my particular case, since I have just implemented a stylesheet switcher in order to enhance certain accessibility aspects, but ironically this particular bug leads to a loss of accessibility.
Does anybody know what might be the reason (version 1.3.2.min related?, cookies related?, etc.) for this and how to solve it?

Disable=true
Feb 27, 2007I have a perl cgi form that has a popup_list. Based on a value that
is coming in from a database query, I want to either
1) display the value (from the databse) and let the user change it;
OR
2) display the value (from the database), but NOT let the user change
it.
I tried using javascript to disable the popup list, and that works,
except the form "loses" the value of the entry in the popup list.
Maybe "disable" is not the correct property I want to use. If that is
the case, what is it?
Disable Right-click
Jul 20, 2005What's the best way to display an image, disabling the user's ability to right-click on it?
I believe you have to use <body oncontextmenu="return false">. Would the
following work?
var x = "<head></head><body oncontextmenu="return false"><img src='temp.jpg' border=0></body>"
top.document.open()
top.document.write(x)
top.document.close()
Since this is a frameless site, I don't think this would work, at least
would never get to the close()...
