I would like to simulate the user pressing tab then enter when they press enter. I know this sounds bad, but I have an asp.net web application that will only allow me to have one form with runat="server" on it so when the user hits return the main form gets submitted. I have another textbox on the page though (that ideally should have it's own form but can't because it is asp), and when enter is hit from there obviously the main form is submitted. The simplest way I could think is to simulate tab then enter using javascript, but I have been unsuccessful in that. I am welcome to any other solutions to this problem. So far I have simulated pressing tab, but I don't know how to simulate more than one keypress though.
Here is the code I have so far, I imagine return 9; needs to be replaced with something else. JQuery will also do.
function suppressEnter (e) {
var keyPressed;
if (window.event) { keyPressed = window.event.keyCode } // IE
else if (e) { keyPressed = e.which }; // Netscape
if (keyPressed == 13) {
return 9;
}
else {
return true;
}
}
EDIT: return 9 + 13; works in chrome, but not IE
Something like this would work:
function keyPress(e) {
if (e.which == 13) {
$(document).trigger(jQuery.Event('keydown', {which: 9}));
// do something
alert('Enter')
}
if (e.which == 9) {
// do something
alert('Tab');
}
};
$(document).bind("keydown", keyPress);
I've coded it up in a fiddle - http://jsfiddle.net/FAe6U/
Also With regards to #nnnnnn comment:
It seems to me you should just code that directly rather than trying
to simulate keystrokes.
Try this:
var tabPress;
function keyPress(e) {
if (e.which == 13) {
if (tabPress == 1){
e.preventDefault();
alert('tab and enter');
}
else{e.preventDefault(); alert('enter')}
}
else if (e.which == 9) {
e.preventDefault();
tabPress = 1;
};
};
function keyRelease(){tabPress = 0;}
$(document).bind("keydown", keyPress);
$(document).bind("keyup", keyRelease);

I have a multistep form using jquery validator plugin that also goes to the next page when you press enter.
function showPage(pg){
$('formError').empty();
$('table:visible').hide();
$('#page-' + pg).show();
$('input[type="text"]:visible').focus();
}
$(document).keydown(function(e) {
if(e.which == 13) {
if($('#msform :input:visible').valid()){
page++;
showPage(page);
}}});
The issue is that if you use the enter button, it triggers a validation error on the next page because the button is still being pressed and it tries to go to the next page.
How can I ignore the enter key for a small period so that releasing the enter key works to go to the next page without attempting to go to the page after the next page?
You can wait for the corresponding keyup event before taking in account a new keydown event for the enter key.
pressed = {};
$(document).keydown(function(e){
if(pressed[e.which] == null && e.which == '13'){
if($('#msform :input:visible').valid()) {
page++;
showPage(page);
}
}
pressed[e.which] = true;
});
$(document).keyup(function(e) {
pressed[e.which] = null;
});
You can use setTimeout() function like this
$(document).keydown(function(e) {
setTimeout(myFunction(),500);
});
function myFunction(){
if(e.which == 13) {
if($('#msform :input:visible').valid()){
page++;
showPage(page);
}}
}
::::::::::::::::::Update::::::::::::::::::
$(document).keydown(function(e) {
if(e.which == 13) {
setTimeout(myFunction(),500);
}
});
function myFunction(){
if($('#msform :input:visible').valid()){
page++;
showPage(page);
}
}
I have a problem I can't seem to sort out.
I have a form with a custom styled button (input type=button). When typing in the text field, I want people to be able to press the TAB key and go to the button. However, it won't use a tab-index so my solution was to highlight the label and change the CSS to give the button a new border color. However, the border color will not change on keypress in any browser other than Firefox.
Here is what I have:
$(function() {
$("#email").bind("keypress", function(e) {
if (e.keyCode == 13) {
send();
return false;
};
if (e.keyCode == 9) {
$("#submit_btn").removeClass('submit1').addClass('submit1after');
};
});
};
The first enter keypress is to serialize and email the form and all.
I can't seem to get it to work for the life of me. What am I doing wrong? Is there a better solution to what I'm trying to accomplish?
Thanks for taking the time,
Armik
Use keydown instead, for me that works (see demo: http://jsfiddle.net/npGtX/2/)
$(function () {
$("#email").bind("keydown", function (e) {
if (e.keyCode == 13) {
send();
return false;
};
if (e.keyCode == 9) {
$("#submit_btn").removeClass('submit1').addClass('submit1after');
};
});
};
Also I found this: Suppressing keyPress for non-character keys?
keypress is not necessarily triggered when the keypress is not a
character. So the browser may not trigger an event on backspace, F1,
the down key, etc.
You can use the keyup event and event object's which property, jQuery normalizes the which property and it's cross-browser:
$(function() {
$("#email").bind("keyup", function(e) {
if (e.which == 13) {
send();
return false;
};
if (e.which == 9) {
$("#submit_btn").toggleClass('submit1 submit1after');
};
});
};
$(function() {
$("#email").keypress(function(e) {
if (e.keyCode == 13 || e.which== 13) {
send();
return false;
};
if (e.keyCode == 9 || e.which== 9) {
$("#submit_btn").removeClass('submit1').addClass('submit1after');
};
});
};
I have a visualforce page (Salesforce) where I'm trying to capture the user pressing enter in a text field and firing a button click.
Here is my jquery code:
$(document).ready(function() {
$("#thisPage\\:theForm\\:siteNumber").keypress(function() {
if(window.event){
key = window.event.keyCode; //IE, chrome
}
else{
key = e.which; //firefox
}
if(key == 13) {
$("#thisPage\\:theForm\\:siteButton").click();
}
});
});
Its very odd, I've verified the key equals 13 and its entering the if statement. I've also tried moving the .click() action above the if key==13 condition and it fires fine. It just doesn't work inside the if key==13 condition I know its entering.
I've recreated what its basically doing in this simple fiddle, but of course it works fine: http://jsfiddle.net/2adPe/
Any help is appreciated!
UPDATE:
I've figured out that this will work
function noenter(e){
if(window.event){
key = window.event.keyCode; //IE, Chrome
}
else{
key = e.which; //firefox
}
if(key == 13) {
document.getElementById('thisPage:theForm:siteButton').click();
return false;
}
else{
return true;
}
}
with
onkeypress="return noenter(event)"
on the textbox. Is there a way to do this unobtrusively??
Try referencing your element IDs using the jQuery Attribute Ends With Selector.
Like this:
$("[id$='input1']").on("keypress",function(e) { // e is the current event
if(e){
key = e.keyCode; // IE, chrome
}
else{
key = e.which; // firefox
}
if(key == 13) {
e.preventDefault(); // prevent a form submit when pressing enter (on IE)
$("[id$='siteButton']").click(); // simulate a click of the siteButton
}
});
Also, you'll want to prevent the default action if the key == 13. Otherwise, the button click might be executed twice.
http://jsfiddle.net/2adPe/3/
Finally got it! I had to remove the e.preventdefault() from before the .click() and add return false at the end that stopped the default action from happening.
$('input[name$="siteNumber"]').keypress(function() {
if(window.event){
key = window.event.keyCode; //IE, chrome
}
else{
key = e.which; //firefox
}
if(key == 13) {
$('input[name$="siteButton"]').click();
return false;
}
});
I have a library that creates an editor on the fly (http://epiceditor.com) and also sets up key shortcuts automatically. The shortcuts can be configured in the options so I can't use e.altKey, e.ctrlKey, etc just a heads up.
For some reason the modifier key isn't being set back to false sometimes on Mac/Ubuntu browsers.
On Windows it seems to happen every time. You can reproduce this by clicking render in JSBin then pressing alt+p. You should see "Yay" appear. Now, if on Windows press just p again. You'll see "Yay appear again. Mac and Ubuntu users have seen this same issue occasionally but it's hard to reproduce it.
Also note this only happens with the alt key it seems. Below I have 16 (shift) next to the 18 (alt). If you swap those out it'll work as expected.
The code for the stripped down test case is:
var modKey = false;
var modKeyCode = 18; //16
document.body.addEventListener('keydown', function (e) {
if (!modKey && modKeyCode == e.keyCode) {
modKey = true;
}
if (modKey && e.keyCode == 80) {
console.log('Yay!');
}
});
document.body.addEventListener('keyup', function (e) {
if (modKey && modKeyCode == e.keyCode) {
modKey = false;
}
});

I do not have access to my Linux box at the moment, so i cannot test your code.
Thus here is more of a suggestion:
Linux (in my experience) is finicky when it it comes to keyCodes and order of key events. Perhaps combine the if(..) from keyup with that of keydown
if (!modKey && modKeyCode == e.keyCode) {
modKey = true;
} else if (modKey && modKeyCode == e.keyCode) {
modKey = false;
}
The above suggestion is made with assumption that you have no specific requirement to have both 'keydown' and 'keyup'.
I've come up with a fix, albeit a sort of crappy fix, but a fix nonetheless.
The fix I went with was to reset the modifier var when any key combo was successful. I.e. one the p in alt+p is pressed reset the modKey to false like this:
var modKey = false;
var modKeyCode = 18; //16
document.body.addEventListener('keydown', function (e) {
if (!modKey && modKeyCode == e.keyCode) {
modKey = true;
}
if (modKey && e.keyCode == 80) {
console.log('Yay!');
modKey = false; //THIS
}
});
document.body.addEventListener('keyup', function (e) {
if (modKey && modKeyCode == e.keyCode) {
modKey = false;
}
});
The problem with this tho is that you can't do back to back key commands. Most of the time this is alright because the user will do a key command like "save" or "preview" or something, type some more, then do another key command. But you wouldn't be able to, let's say: alt+p s to trigger alt+p then alt+s without having to let go of the alt key.
How to overwrite or remove key events, that is on a website? I'm writing a script for GreaseMonkey and I want to make event on Enter button, but when I press the ENTER button, it triggers function on website.
EDIT 1: Here is the website, that I need to do this http://lockerz.com/auth/express_signup
One of these two should do it for you. I used the first one, although someone on SO told me the second one will work also. I went for the hammer.
Sorry, first one wasn't a cut and paste answer. I use using it to return up/down arrow control on a website. I changed it so that it identifies keycode 13 instead.
(function() {
function keykiller(event) {
if (event.keyCode == 13 )
{
event.cancelBubble = true;
event.stopPropagation();
return false;
}
}
window.addEventListener('keypress', keykiller, true);
window.addEventListener('keydown', keykiller, true);
})();
Searching quickly on SO:
jQuery Event Keypress: Which key was pressed?
Code from there:
var code = (e.keyCode ? e.keyCode : e.which);
if(code == 13) { //Enter keycode
//Do something
}
Without a library, use: http://jsfiddle.net/4FBJV/1/.
document.addEventListener('keypress', function(e) {
if(e.keyCode === 13) {
alert('Enter pressed');
return false;
}
});
