Number in textfield should be autoformatted only after user clicks outside the textbox?

I have a problem. Basically, what happens in my case is that the numbers in my textbox are autoformatted as I type. I don't want this to happen. What I want is that the numbers should be autoformatted only when the user clicks outside the textbox.
In my input tag I have :
onkeyup="format(event, this);"
My javascript function is :
function format(e, obj) {
if (e.keyCode == 36) {
press1(obj);
}
if (e.keyCode == 13) {
return false;
}
if ((e.keyCode <= 34) || (e.keyCode >= 46 && e.keyCode < 58) || (e.keyCode >= 96 && e.keyCode <= 105)) { // //alert(e.keyCode);
obj.value = CommaFormatted(obj.value);
} else {
if (e && e.stopPropagation) {
e.stopPropagation();
e.preventDefault();
} else {
e.cancelBubble = true;
e.returnValue = false;
}
return false;
}
}
where the press1 function is:
function press1(textControlID) {
var text = textControlID;
if (text.getAttribute("maxlength") == text.value.length) {
var FieldRange = text.createTextRange();
FieldRange.moveStart('character', text.value.length);
FieldRange.collapse();
FieldRange.select();
return true;
}
if (text != null && text.value.length > 0) {
if (text.createTextRange) {
var FieldRange = text.createTextRange();
FieldRange.moveStart('character', text.value.length);
FieldRange.collapse();
FieldRange.select();
} else if (text.setSelectionRange) {
var textLength = text.value.length;
text.setSelectionRange(textLength, textLength);
}
}
}
I really hope this could be solved. Please!

You could change onkeyup to onblur, which is the event that gets fired when the control loses focus - clicking out of it.
The onkeyup event fires with every keypress.

How to detect when an enter is pressed using jQuery?

I am trying to detect what key is pressed and based on that I want to fire click() event.
My code work for all the key except for the enter.
for some reason when I press "enter" I do not get any messages on the screen as if the enter button was not pressed.
Here is my code
$(function(){
$(document).keypress(function(e) {
handleKeyPress(e);
});
function handleKeyPress( e ){
var key = e.which;
alert(key);
if( getIcwsTabIndex() != 1){
return;
}
if( key >= 48 && key <= 57){
var k = key - 48;
$('#icwsDialerNumber' + k).click();
}
if( key == 8){
e.preventDefault();
$('#icwsDialerScreenDel').click();
}
if( key == 13){
e.preventDefault();
$('#icwsDialerNumberDial').click();
}
}
});
what am I doing wrong here?

tested your code, it works on chrome besides the not defined getIcwsTabIndex
so verify it is ok on your side
here is a fiddle check the console
$(function(){
$(document).keypress(function(e) {
handleKeyPress(e);
});
function handleKeyPress( e ){
var key = e.which;
console.log(key);
// if( getIcwsTabIndex() != 1){
// return;
// }
if( key >= 48 && key <= 57){
var k = key - 48;
$('#icwsDialerNumber' + k).click();
}
if( key == 8){
e.preventDefault();
$('#icwsDialerScreenDel').click();
}
if( key == 13){
e.preventDefault();
console.log(key);
$('#icwsDialerNumberDial').click();
}
}
});

The problem with your code is that is not cross-browser. It should be:
var key = e.charCode || e.keyCode || 0;

Unable To get Selected text on Enter key press from list box

My Code for click

if (e.keyCode != 40 && e.keyCode != 38 && e.keyCode != 13) {
var str1 = str.value;
var str2 = str1.replace(' ', '+')
var url = "../SiteCache/90D/SmartGetQuoteData.aspx?Type=EQ&text=" + str2;
$("#ajax_response_smart").load(url);
}
$("#ajax_response_smart").show();

$current;
if (key != 40 && key != 38 && key != 13)
{ return; }
else {
$listItems.removeClass('ui-state-hover');
}
if (key == 40) // Down key
{
if (!$selected.length || $selected.is(':last-child')) {
$current = $listItems.eq(0);
}
else {
$current = $selected.next();
}
}
else if (key == 38) // Up key
{
if (!$selected.length || $selected.is(':first-child')) {
$current = $listItems.last();
}
else {
$current = $selected.prev();
}
}
else if (key == 13) {
}
}
else {
$("#ajax_response_smart").hide();
}
if (typeof $current != "undefined") {
$current.addClass('ui-state-hover');

Firefox keydown backspace issue

I'm building a terminal emulation and running into an issue with capturing backspace in Firefox. I'm able to nab the first backspace and remove the last character on the input at the prompt, but it won't persist and remove more than one character.
Actual website: http://term.qt.io/
Replication here: http://jsfiddle.net/BgtsE/1/
JavaScript code
function handleKeys(e){
var evt = e || window.event;
var key = evt.charCode || evt.keyCode;
if(evt.type == "keydown")
{
curr_key = key;
if(key == 8)
{
evt.preventDefault();
if(0 < $('body').text().length)
$('body').text($('body').text().slice(0,-1));
}
}
else if(evt.type == "keypress")
{
if(97 <= key && key <= 122)
{
if(curr_key != key)
$('body').append(String.fromCharCode(key));
}
else
$('body').append(String.fromCharCode(key));
}
}
$(function(){
$('html').live({
keydown:function(e){
handleKeys(e);
},
keypress:function(e){
handleKeys(e);
}
})
})​

Try this: http://jsfiddle.net/NBZG8/1/
You'll need to handle backspace in both keydown and keypress to support Chrome and Firefox
function handleKeys(e){
var evt = e || window.event;
var key = evt.charCode || evt.keyCode;
if (evt.type == "keydown") {
curr_key = key;
if(key == 8 && !$.browser.mozilla) {
backspaceHandler(evt);
}
} else if (evt.type == "keypress") {
if (key == 8) {
backspaceHandler(evt);
} else if (97 <= key && key <= 122) {
if(curr_key != key) {
$('body').append(String.fromCharCode(key));
}
} else {
$('body').append(String.fromCharCode(key));
}
}
}
function backspaceHandler(evt) {
evt.preventDefault();
if(0 < $('body').text().length) {
$('body').text($('body').text().slice(0,-1));
}
};
$(function(){
$('html').live({
keydown : handleKeys,
keypress : handleKeys
})
})​

In firefox Windows 17.0.1 any value returned by $("selector").text() has an added new line character appended to the end. So the substring didn't work for me:
<html>
<head>
<title>test</title>
<script src="jquery.js"></script>
<script>
$("document").ready(function(){
console.log("body text seems to have a new line character");
console.log(($('body').text()[5]=="\n"));
});
function handleKeys(e){
var evt = e || window.event;
var key = evt.charCode || evt.keyCode;
if(evt.type == "keydown")
{
curr_key = key;
if(key == 8)
{
evt.preventDefault();
if(0 < $('body').text().length)
// next line works, you might trim the \n if it's there at the end
//$('body').text($('body').text().slice(0,-2));
// this one didn't work for me
$('body').text($('body').text().substring(0,$('body').text().length-1));
}
}
else if(evt.type == "keypress")
{
if(97 <= key && key <= 122)
{
if(curr_key != key)
$('body').append(String.fromCharCode(key));
}
else
$('body').append(String.fromCharCode(key));
}
}
$(function(){
$('html').live({
keydown:function(e){
handleKeys(e);
},
keypress:function(e){
handleKeys(e);
}
})
})
</script>
</head>
<body>12345</body>
</html>

I had the same issue with keypress on mozilla.
Thanks to this subject it solves my problem so I'll post my code if anyone try to do the same thing as me.
In my exemple I try to auto space when the user type two numbers, and it didn't work in Firefox so that's my code :
$(function() {
$('#field1, #field2').on('keypress',function(event) {
event = event || window.event;
var charCode = event.keyCode || event.which,
lgstring = $(this).val().length,
trimstring;
if(charCode === 8) {
event.returnValue = false;
if(event.preventDefault)
event.preventDefault();
if(0 < $(this).val().length) {
$(this).val($(this).val().slice(0,-1));
}
}
else if(((charCode > 31) && (charCode < 48 || charCode > 57)) || lgstring >= 14) {
event.returnValue = false;
if(event.preventDefault)
event.preventDefault();
}
else {
trimstring = $(this).val().replace(/ /g,"");
if((lgstring !== 0) && (trimstring.length % 2) === 0 ) {
$(this).val($(this).val() + ' ');
}
}
});
});
I noticed that Mozilla handle the backspace as a keypress where Chrome don't.
Sorry for my English I'm French

$('#id').keypress(function(e) {
if(e.charCode > 0 || e.keyCode === 8){
if(e.keyCode === 8){
return true;
}else if((e.charCode !== 0) && ((e.charCode > 57 && e.charCode < 65)){
return false;
}
}else if((e.keyCode !== 0) && ((e.keyCode > 57 && e.keyCode < 65)){
return false;
}
});

javascript validation for allow -1 and all positive numbers in text box

I am trying to validate a text box to allow all positive numbers including -1 in it.
i tried this, which will work for allowing only positive numbers
function allownumbers(e, txtBox) {
var key;
key = (e.keyCode) ? e.keyCode : e.charCode;
if (e.charCode == 0) {
return true;
}
if ((key < 48 || key > 57) && (key != 46) && (key != 44)) {
return false;
}
if (key == 46) {
if ((txtBox.value).indexOf('.') != -1) {
return false;
}
}
if (key == 44) {
if ((txtBox.value).indexOf(',') != -1) {
return false;
}
}
return true;
}
But how to allow -1(only) with all positive numbers
Thanks in advance

Instead of preventing keystrokes, why not validate and sanitize the input? Maybe something like this:
function allownumbers(e, txtBox) {
var val = parseInt(txtBox.value);
if(!val || val < -1) {
val = 0; // invalid value, reset to zero
}
txtBox.value = val;
}
