search when press enter not when typing with livesearch.js

I tried to search when press enter, here I use livesearch.js for searching but this js always search when typing. I want it search when press enter. So iI tried change but still not working.
Framework js
<script type="text/javascript" src="framework/liveSearch/livesearch.js"></script>
HTML
<input type="text" id="livesearch" class="livesearch" style="margin-top:0;"/>
<div class="searchresult" id="liveRequestResults"></div>
<iframe id="mainResult" src='log-list.php'></iframe>
Javascript
<script>
$('#livesearch').keydown(function(e) {
if(e.keyCode == 13) // I tried this code, first enter worked, after that back to search when typing
{
liveReqInit('livesearch','liveRequestResults','log-ls.php','','mainResult'); //this search work when typing
}
})
</script>

From what I understood, you want a normal search box. This is going go submit the value to your backend(which I assume is log-ls.php).
<form action="log-ls.php">
<input type="search" placeholder="Search..." name="search">
<button type="submit" value="Submit">Submit</button>
</form>

onkeypress is not working in form

I have the following problem with this code:
<form>
<div class="searchBarDiv"> <input class="searchBar" id="search" type="search"
placeholder="Suche" onkeypress="search();"> </div>
</form>
search(); won't get fired if i press a key. But when i remove the <form></form> everything works fine.
Is there any way to fire onkeypress in a form or any other function?
I`m using PhoneGap and jQuery. It won't work in a Browser or on a mobile Device.
Any help would be nice. Thank you in advance!
Edit:
Solved by A. Wolff: You can't use the id 'search' in a form. Thank you all for you answers and solutions.

I would suggest something more like this. Remove the onkeypress from the input, and as per #A.Wolff's comment on the question, change the search input's ID. Then add the following JS on document ready.
$("#search_inp").keypress(search);
Make sure that the search function takes an event parameter if you need to know which key was pressed.

Try to change your js function name or input id , your problem is because id and function name are same .
<form>
<div class="searchBarDiv"> <input class="searchBar" id="search" type="search"
placeholder="Suche" onkeypress="searchData();"> </div>
</form>
<script type="text/javascript">
function searchData(){
alert("2222");
}
</script>

Check if checkbox is checked then send

I have this markup:
<form action="http://acumbamail.com/signup/13565/" method="POST">
<input type="checkbox" id="privacidad-btn" > Acepto política de privacidad<br>
<input type="button" value="Enviar" id="submit_acumba">
</form>
I want that if the user clicks on the button without checkbox checked there is an alert that he must agree to the terms (check the checkbox). Any ideas on the best approach to this?
I'm starting doing this way but don't know how which way to go:
if (jQuery("#privacidad-btn").is(":checked")) {
}

One approach that i like with html5 is the form validation
just put required on the checkbox and when the try to submit it they will be alerted with a popover dialog in there own language (its a good highlighter in the form of what is wrong with it)
<input required type="checkbox" id="privacidad-btn">
You could do it the way tymeJV suggest with button clicked event $("#submit_acumba").click(...)
That way you would support more browsers. but: It would just only validate on a click of a button
But there is the form submit event as well.
$("form").submit(function(e) {
if ( ! jQuery("#privacidad-btn").is(":checked")) {
// Not checked abort the default submit
e.preventDefault();
}
});
The difference is that it has to do all the native form validation before -> if it is invalid it won't trigger a submit or call the function
with button.onclick it would avoid the native validation since it would run before the submit event

You need a handler for the button as well:
$("#submit_acumba").click(function(e) {
e.preventDefault();
if (jQuery("#privacidad-btn").is(":checked")) {
//submit!
}
})

Using this straight and simple HTML implementation, you can do this without any special scripting (JavaScript/jQuery):
<form>
<p><input type="checkbox" required name="terms"> I accept the <u>Terms and Conditions</u></p>
<p><input type="submit"></p>
</form>
Here's a JSFiddle link where you can play with this implementation: http://jsfiddle.net/zs9b167b/

Javascript login form doesn't submit when user hits Enter

I'm working on a simple javascript login for a site, and have come up with this:
<form id="loginwindow">
<strong>Login to view!</strong>
<p><strong>User ID:</strong>
<input type="text" name="text2">
</p>
<p><strong>Password:</strong>
<input type="password" name="text1"><br>
<input type="button" value="Check In" name="Submit" onclick=javascript:validate(text2.value,"username",text1.value,"password") />
</p>
</form>
<script language = "javascript">
function validate(text1,text2,text3,text4)
{
if (text1==text2 && text3==text4)
load('album.html');
else
{
load('failure.html');
}
}
function load(url)
{
location.href=url;
}
</script>
...which works except for one thing: hitting enter to submit the form doesn't do anything. I have a feeling it's cause I've used "onclick" but I'm not sure what to use instead. Thoughts?
Okay yeah so I'm well aware of how flimsy this is security-wise. It's not for anything particularly top secret, so it's not a huge issue, but if you guys could elaborate on your thoughts with code, I'd love to see your ideas. the code i listed is literally all I'm working with at this point, so I can start from scratch if need be.

There are several topics being discussed at once here. Let's try to clarify.
1. Your Immediate Concern:
(Why won't the input button work when ENTER is pressed?)
Use the submit button type.
<input type="submit".../>
..instead of
<input type="button".../>
Your problem doesn't really have anything to do with having used an onclick attribute. Instead, you're not getting the behavior you want because you've used the button input type, which simply doesn't behave the same way that submit buttons do.
In HTML and XHTML, there are default behaviors for certain elements. Input buttons on forms are often of type "submit". In most browsers, "submit" buttons fire by default when ENTER is pressed from a focused element in the same form element. The "button" input type does not. If you'd like to take advantage of that default behavior, you can change your input type to "submit".
For example:
<form action="/post.php" method="post">
<!--
...
-->
<input type="submit" value="go"/>
</form>
2. Security concerns:
#Ady mentioned a security concern. There are a whole bucket of security concerns associated with doing a login in javascript. These are probably outside of the domain of this question, especially since you've indicated that you aren't particularly worried about it, and the fact that your login method was actually just setting the location.href to a new html page (indicating that you probably don't have any real security mechanism in place).
Instead of drudging that up, here are links to related topics on SO, if anyone is interested in those questions directly.
Is there some way I can do a user validation client-side?
Encrypting Ajax calls for authentication in jQuery
3. Other Issues:
Here's a quick cleanup of your code, which just follows some best practices. It doesn't address the security concern that folks have mentioned. Instead, I'm including it simply to illustrate some healthy habits. If you have specific questions about why I've written something a certain way, feel free to ask. Also, browse the stack for related topics (as your question may have already been discussed here).
The main thing to notice is the removal of the event attributes (onclick="", onsubmit="", or onkeypress="") from the HTML. Those belong in javascript, and it's considered a best practice to keep the javascript events out of the markup.
<form action="#" method="post" id="loginwindow">
<h3>Login to view!</h3>
<label>User ID: <input type="text" id="userid"></label>
<label>Password: <input type="password" id="pass"></label>
<input type="submit" value="Check In" />
</form>
<script type="text/javascript">
window.onload = function () {
var loginForm = document.getElementById('loginwindow');
if ( loginwindow ) {
loginwindow.onsubmit = function () {
var userid = document.getElementById('userid');
var pass = document.getElementById('pass');
// Make sure javascript found the nodes:
if (!userid || !pass ) {
return false;
}
// Actually check values, however you'd like this to be done:
if (pass.value !== "secret") {
location.href = 'failure.html';
}
location.href = 'album.html';
return false;
};
}
};
</script>

Put the script directly in your html document. Change the onclick value with the function you want to use. The script in the html will tell the form to submit when the user hits enter or press the submit button.
<form id="Form-v2" action="#">
<input type="text" name="search_field" placeholder="Enter a movie" value=""
id="search_field" title="Enter a movie here" class="blink search-field" />
<input type="submit" onclick="" value="GO!" class="search-button" />
</form>
<script>
//submit the form
$( "#Form-v2" ).submit(function( event ) {
event.preventDefault();
});
</script>

Instead of <input type="button">, use <input type="submit">. You can put your validation code in your form onsubmit handler:
<form id="loginwindow" onsubmit="validate(...)">

it's because it's not a form submitting, so there's no event to be triggered when the user presses enter. An alternative to the above form submit options would be to add an event listener for the input form to detect if the user pressed enter.
<input type="password" name="text1" onkeypress="detectKey(event)">

Maybe you can try this:
<form id="loginwindow" onsubmit='validate(text2.value,"username",text1.value,"password")'>
<strong>Login to view!</strong>
<p><strong>User ID:</strong>
<input type="text" name="text2">
</p>
<p><strong>Password:</strong>
<input type="password" name="text1"><br>
<input type="submit" value="Check In"/>
</p>
</form>
As others have pointed out, there are other problems with your solution. But this should answer your question.

Surely this is too unsecure as everyone can crack it in a second ...
-- only pseudo-secure way to do js-logins are the like:
<form action="http://www.mySite.com/" method="post" onsubmit="this.action+=this.theName.value+this.thePassword.value;">
Name: <input type="text" name="theName"><br>
Password: <input type="password" name="thePassword"><br>
<input type="submit" value="Login now">
</form>

My Thought = Massive security hole. Anyone can view the username and password.
More relevant to your question: - You have two events happening.
User clicks button.
User presses enter.
The enter key submits the form, but does not click the button.
By placing your code in the onsubmit method of the form the code will run when the form is submitted. By changing the input type of the button to submit, the button will submit the form in the same way that the enter button does.
Your code will then run for both events.

How to submit a form when the return key is pressed?

Can someone please tell me how to submit an HTML form when the return key is pressed and if there are no buttons in the form?
The submit button is not there. I am using a custom div instead of that.

To submit the form when the enter key is pressed create a javascript function along these lines.
function checkSubmit(e) {
if(e && e.keyCode == 13) {
document.forms[0].submit();
}
}
Then add the event to whatever scope you need eg on the div tag:
<div onKeyPress="return checkSubmit(event)"/>
This is also the default behaviour of Internet Explorer 7 anyway though (probably earlier versions as well).

IMO, this is the cleanest answer:
<form action="" method="get">
Name: <input type="text" name="name"/><br/>
Pwd: <input type="password" name="password"/><br/>
<div class="yourCustomDiv"/>
<input type="submit" style="display:none"/>
</form>
Better yet, if you are using javascript to submit the form using the custom div, you should also use javascript to create it, and to set the display:none style on the button. This way users with javascript disabled will still see the submit button and can click on it.
It has been noted that display:none will cause IE to ignore the input. I created a new JSFiddle example that starts as a standard form, and uses progressive enhancement to hide the submit and create the new div. I did use the CSS styling from StriplingWarrior.

I tried various javascript/jQuery-based strategies, but I kept having issues. The latest issue to arise involved accidental submission when the user uses the enter key to select from the browser's built-in auto-complete list. I finally switched to this strategy, which seems to work on all the browsers my company supports:
<div class="hidden-submit"><input type="submit" tabindex="-1"/></div>
.hidden-submit {
border: 0 none;
height: 0;
width: 0;
padding: 0;
margin: 0;
overflow: hidden;
}
This is similar to the currently-accepted answer by Chris Marasti-Georg, but by avoiding display: none, it appears to work correctly on all browsers.
Update
I edited the code above to include a negative tabindex so it doesn't capture the tab key. While this technically won't validate in HTML 4, the HTML5 spec includes language to make it work the way most browsers were already implementing it anyway.

Use the <button> tag. From the W3C standard:
Buttons created with the BUTTON element function just like buttons created with the INPUT element, but they offer richer rendering possibilities: the BUTTON element may have content. For example, a BUTTON element that contains an image functions like and may resemble an INPUT element whose type is set to "image", but the BUTTON element type allows content.
Basically there is another tag, <button>, which requires no javascript, that also can submit a form. It can be styled much in the way of a <div> tag (including <img /> inside the button tag). The buttons from the <input /> tag are not nearly as flexible.
<button type="submit">
<img src="my-icon.png" />
Clicking will submit the form
</button>
There are three types to set on the <button>; they map to the <input> button types.
<button type="submit">Will submit the form</button>
<button type="reset">Will reset the form</button>
<button type="button">Will do nothing; add javascript onclick hooks</button>
Standards
W3C wiki about <button>
HTML5 <button>
HTML4 <button>
I use <button> tags with css-sprites and a bit of css styling to get colorful and functional form buttons. Note that it's possible to write css for, for example, <a class="button"> links share to styling with the <button> element.

Here is how I do it with jQuery
j(".textBoxClass").keypress(function(e)
{
// if the key pressed is the enter key
if (e.which == 13)
{
// do work
}
});
Other javascript wouldnt be too different. the catch is checking for keypress argument of "13", which is the enter key

I believe this is what you want.
//<![CDATA[
//Send form if they hit enter.
document.onkeypress = enter;
function enter(e) {
if (e.which == 13) { sendform(); }
}
//Form to send
function sendform() {
document.forms[0].submit();
}
//]]>
Every time a key is pressed, function enter() will be called. If the key pressed matches the enter key (13), then sendform() will be called and the first encountered form will be sent. This is only for Firefox and other standards compliant browsers.
If you find this code useful, please be sure to vote me up!

Use the following script.
<SCRIPT TYPE="text/javascript">
<!--
function submitenter(myfield,e)
{
var keycode;
if (window.event) keycode = window.event.keyCode;
else if (e) keycode = e.which;
else return true;
if (keycode == 13)
{
myfield.form.submit();
return false;
}
else
return true;
}
//-->
</SCRIPT>
For each field that should submit the form when the user hits enter, call the submitenter function as follows.
<FORM ACTION="../cgi-bin/formaction.pl">
name: <INPUT NAME=realname SIZE=15><BR>
password: <INPUT NAME=password TYPE=PASSWORD SIZE=10
onKeyPress="return submitenter(this,event)"><BR>
<INPUT TYPE=SUBMIT VALUE="Submit">
</FORM>

I use this method:
<form name='test' method=post action='sendme.php'>
<input type=text name='test1'>
<input type=button value='send' onClick='document.test.submit()'>
<input type=image src='spacer.gif'> <!-- <<<< this is the secret! -->
</form>
Basically, I just add an invisible input of type image (where "spacer.gif" is a 1x1 transparent gif).
In this way, I can submit this form either with the 'send' button or simply by pressing enter on the keyboard.
This is the trick!

Why don't you just apply the div submit styles to a submit button? I'm sure there's a javascript for this but that would be easier.

If you are using asp.net you can use the defaultButton attribute on the form.

I think you should actually have a submit button or a submit image... Do you have a specific reason for using a "submit div"? If you just want custom styles I recommend <input type="image".... http://webdesign.about.com/cs/forms/a/aaformsubmit_2.htm

Extending on the answers, this is what worked for me, maybe someone will find it useful.
Html
<form method="post" action="/url" id="editMeta">
<textarea class="form-control" onkeypress="submitOnEnter(event)"></textarea>
</form>
Js
function submitOnEnter(e) {
if (e.which == 13) {
document.getElementById("editMeta").submit()
}
}

Similar to Chris Marasti-Georg's example, instead using inline javascript.
Essentially add onkeypress to the fields you want the enter key to work with. This example acts on the password field.
<html>
<head><title>title</title></head>
<body>
<form action="" method="get">
Name: <input type="text" name="name"/><br/>
Pwd: <input type="password" name="password" onkeypress="if(event.keyCode==13) {javascript:form.submit();}" /><br/>
<input type="submit" onClick="javascript:form.submit();"/>
</form>
</body>
</html>

Since display: none buttons and inputs won't work in Safari and IE, I found that the easiest way, requiring no extra javascript hacks, is to simply add an absolutely positioned <button /> to the form and place it far off screen.
<form action="" method="get">
<input type="text" name="name" />
<input type="password" name="password" />
<div class="yourCustomDiv"/>
<button style="position:absolute;left:-10000px;right:9990px"/>
</form>
This works in the current version of all major browsers as of September 2016.
Obviously its reccomended (and more semantically correct) to just style the <button/> as desired.

Using the "autofocus" attribute works to give input focus to the button by default. In fact clicking on any control within the form also gives focus to the form, a requirement for the form to react to the RETURN. So, the "autofocus" does that for you in case the user never clicked on any other control within the form.
So, the "autofocus" makes the crucial difference if the user never clicked on any of the form controls before hitting RETURN.
But even then, there are still 2 conditions to be met for this to work without JS:
a) you have to specify a page to go to (if left empty it wont work). In my example it is hello.php
b) the control has to be visible. You could conceivably move it off the page to hide, but you cannot use display:none or visibility:hidden.
What I did, was to use inline style to just move it off the page to the left by 200px. I made the height 0px so that it does not take up space. Because otherwise it can still disrupt other controls above and below. Or you could float the element too.
<form action="hello.php" method="get">
Name: <input type="text" name="name"/><br/>
Pwd: <input type="password" name="password"/><br/>
<div class="yourCustomDiv"/>
<input autofocus type="submit" style="position:relative; left:-200px; height:0px;" />
</form>
