I'm trying to create a little search box that allows you to search Twitter based on the keyword you enter in the input field. While it's work, it only works if you press the Submit button. I would also like to be able to press the Enter or Return key to initiate the search. I've tried using the .sumbit function and wrapping my input around a form element with no success. Any insight would be greatly appreciate!

var searchTerm = 'http://search.twitter.com/search.json?q=' + $('#twitterSearch').val() + '&callback=?'
$.getJSON(searchTerm, function(data) {
$.each(data.results, function() {
$('<div class="results"></div>')

To trigger the onclick function in jQuery, click() method is used. For example, on clicking a paragraph on a document, a click event will be triggered by the $(“p”). click() method. The user can attach a function to a click method whenever an event of a click occurs to run the function.
To trigger a click button on ENTER key, We can use any of the keyup(), keydown() and keypress() events of jQuery. keyup(): This event occurs when a keyboard key is released. The method either triggers the keyup event, or to run a function when a keyup event occurs.
To check if an “enter” key is pressed inside a textbox, just bind the keypress() to the textbox. $('#textbox'). keypress(function(event){ var keycode = (event.
How to trigger HTML button after hitting enter button in textbox using JavaScript ? Given an HTML document containing text area and the task is to trigger the button when the user hit Enter button. We can do it by using “keyup”, “keydown”, or “keypress” event listener on textbox depending on the need.
EDIT: As Spudley suggested "one of the main points of using jQuery is to stop you having to use event triggers embedded in the HTML markup" so a better solution would be
<script>
$(document).ready(function(){
function(data) {
$('#twitterSearch').keydown(function(event){
if(event.keyCode==13){
$('#startSearch').trigger('click');
}
});
$('#startSearch').click(function(){
$('#tweets .results').remove();
var searchTerm = 'http://search.twitter.com/search.json?q=' + $('#twitterSearch').val() + '&callback=?'
$.getJSON(searchTerm, function(data) {
$.each(data.results, function() {
$('<div class="results"></div>')
.hide()
.append('<a class="userPicLink" href="http://twitter.com/' + this.from_user + '">' + '<img class="userImg" src="' + this.profile_image_url + '">' + '</a>')
.append('<span class="userName">' + '<a href="http://twitter.com/' + this.from_user + '">' + this.from_user + '</span>')
.append('<span class="userText">' + this.text + '</span>')
.append('<time class="textTime">' + relTime(this.created_at) + '</time>')
.appendTo('#tweets')
.fadeIn();
});
});
</script>
OR - Previous proposal:
<input type="search" onkeydown="if(event.keyCode==13)$('#startSearch').trigger('click');" list="searchSugg" id="twitterSearch" placeholder="css3 animation" required aria-required="true" >
If you want place event with not obtrusive js then you can use also this system:
$("#element").keydown(function(event) {
if (event.keyCode == 13) {
// do stuff
}
also if you have a submit button, this is an alternative, #element must be the text field where you want catch the event.
