Don't execute a keydown function if some divs are clicked

My script execute some actions (like stop one audio player) in case the user press the space bar:
$('html').keydown(function(e){
if(e.keyCode == 32){
// Stop the audio player
}
}
But the problem comes when a user tries to write a message in the textarea because the previous function executes (and it's very annoying)... How can I do to not execute the function, in case the user is writing a message on a textarea or other elements?

You need to skip when user is focussing some control, this example will prevent the player to stop if user i typing in a text area.
$(function () {
$(document).keypress(function (e, f) {
var tagName = e.target.tagName.toLowerCase();
if (tagName != 'textarea') {
if (e.keyCode == 32) {
console.log('Stop Playing');
}
}
});
});
Hopw this helps.

Try this,
$('#textAreaId').keypress(function(e){
e.preventDefault();
});

Use stopPropagation method on event object when space bar pressed on textarea.
$(document).ready(function(){
$("#testTextArea").keydown(function(e){
if(e.keyCode == 32){
e.stopPropagation();
}
});
$("#container").keydown(function(e){
if(e.keyCode == 32){
alert('Player Stoped/Started')
}
});
})

Try This :)
$('html').keydown(function(e) {
if(e.keyCode == 32){
// stop the music player
}
});
$('input, textarea').keydown(function(e) {
e.stopPropagation();
});

Something like this:
The code inside the if statement only triggers if you are not focused inside a text area or input.
jsfiddle demo
HTML:
<textarea></textarea>
<input type="text">
jQuery:
var exclude = $("textarea, input");
$('html').on("keydown", function( e ) {
if ( e.keyCode == 32 && !exclude.is(':focus') ) {
console.log( 'Space pressed outside input or text area' );
}
});

You should check the sender of the event, if the sender is other controls then the audio player then ignore the call, otherwise stop the player.
$('html').keydown(function(e){
var senderID = $(event.target).attr('id');
if(senderID == 'myAudioPlayerID' && e.keyCode == 32){
// Stop the audio player
}
}

Submitting a comment when pressing enter in Textarea

How do i force a comment by pressing enter? At the moment when i press enter it builds a new line. I've seen quite a few articles here on SO but I can't seem to figure it out.
Here's what I've tried:
function enterForm(event) {
if(event.keyCode == 13) {
runForm();
}
}
function enterForm(event) {
if(event.keyCode == 13) {
runForm();
}
}
Adding onKeyUp=”enterForm(event)” in the textarea tag. Didn't work.
I also tried something like this:
$('.cmnt_new').on('keyup', function(e) {
if (e.which == 13 && ! e.shiftKey) {
// your AJAX call
}
});

try keypress as found here:
Submitting a form on 'Enter' with jQuery?
$('.input').keypress(function(e) {
if(e.which == 13) {
jQuery(this).blur();
jQuery('#submit').focus().click();
}
});

Keypress to change class in jQuery

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');
};
});
};

Simulate multiple keypresses in javascript

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);

Overwriting key events

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;
}
});
