Javascript/Php Chat - Enter isn't work in one textbox - javascript

So I made a chat with textboxs. If I press ENTER the chat send the message. It's fine, but in "Warning" thing this isn't work. When I'm pressing Enter, it isn't work. Can someone help me?
//This is for normal users:
<form name="message" action="">
<input name="usermsg" type="text" id="usermsg" size="63" />
<input name="submitmsg" type="submit" id="submitmsg" value="Send" />
</form>
<br>
//This is for moderators:
<form name="moderating" method="post" action="">
<hr align="center">
<br>
<p><b>Write in color:</b></p>
<script type="text/javascript" src="color_picker/jscolor.js"></script>Select color: <input class="color" name="color_value" type="text" id="color_value" value="FF0F0F">
<input name="colormsg" type="text" id="colormsg" size="25" />
<input name="submitcolormsg" type="submit" id="submitcolormsg" value="Send" />
<br><br>
<p><b>Warning</b></p>
//Is this wrong?! :
<input name="warningmsg" type="text" id="warningmsg" size="63" />
<input name="submitwarningmsg" type="submit" id="submitwarningmsg" value="Warning" />
<br><br>
<p><b>Clear chat log</b></p>
<input name="clear_button" type="submit" id="clear_button" value="Clear" />
<br><br>
<p><b>Turn on/off chat</b></p>
<input type="radio" name="chat_status_group" id="on" value="on" checked><b>On</b> -<input type="radio" name="chat_status_group" id="off" value="off"><b>Off</b> <input name="chat_status_button" type="submit" id="chat_status_button" value="Ok" />
</form>
</div>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3/jquery.min.js"></script>
<script type="text/javascript">
// jQuery Document
$(document).ready(function(){
$("#submitmsg").click(function(){
var clientmsg = $("#usermsg").val();
$.post("***.php", {text: clientmsg});
$("#usermsg").attr("value", "");

});
$("#submitcolormsg").click(function(){
var clientcolormsg = $("#colormsg").val();
var color = $("#color_value").val();
$.post("***.php", {
text: clientcolormsg,
color: color
});
$("#colormsg").attr("value", "");
return false;
});
//And here is the wrong?! :
$("#submitwarningmsg").click(function(){
var post_warningmsg = $("#warningmsg").val();
$.post("***.php", {text: post_warningmsg});
$("#warningmsg").attr("value", "");
return false;
});
$("#clear_button").click(function(){
$.post("clear.php");
return false;
});
$("#chat_status_button").click(function(){
var statusmsg = "on";
if(document.getElementById('on').checked) {
statusmsg = "on";
} else {
statusmsg = "off";
}
$.post("chat_status.php", {
text: statusmsg
});
return false;
});
.
.
.
});
</script>
</body>
</html>
I think the problem is here:
$("#submitwarningmsg").click(function(){
var post_warningmsg = $("#warningmsg").val();
$.post("***.php", {text: post_warningmsg});
$("#warningmsg").attr("value", "");
return false;
});
why
$("#warningmsg").attr("value", "");
isn't work?


It doesn't work because you are only checking for a click, not submit. Try changing the last code to:
$("#submitwarningmsg").submit(function(e){
e.preventDefault();
var post_warningmsg = $("#warningmsg").val();
$.post("***.php", {text: post_warningmsg});
$("#warningmsg").val("");
return false;
});
Besides, you are forgetting to open your form in the last 'form':
<form>

input a button value on corresponding textbox that is on focus

I am trying to create a touchscreen calculator like where the button value will be placed on the textbox after i set it on a focus by clicking but it appears on all the textboxes.I tried to use the code
if ($(impo).is(":focus")) {
but it doesnt work. Please see my snippet
Thanks in advance!
var impo = document.getElementById("imp_text");
var tess = document.getElementById("tess_text");
var FKeyPad = document.Keypad;
var Accumulate = 0;
var FlagNewNum = false;
var PendingOp = "";
document.getElementById('tess').onclick = function() {
document.getElementById('tess_text').focus();
}
document.getElementById('imp').onclick = function() {
document.getElementById('imp_text').focus();
}
function NumPressed(Num) {
if (impo) {
if (FlagNewNum) {
FKeyPad.ReadOut.value = Num;
FlagNewNum = false;
} else {
if (FKeyPad.ReadOut.value == " ")
FKeyPad.ReadOut.value = Num;
else
FKeyPad.ReadOut.value += Num;
}
}
if (tess) {
if (FlagNewNum) {
FKeyPad.readtess.value = Num;
FlagNewNum = false;
} else {
if (FKeyPad.readtess.value == " ")
FKeyPad.readtess.value = Num;
else
FKeyPad.readtess.value += Num;
}
}
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<html lang="en">
<head>
</head>
<body>
<form name="Keypad" action="">
<input type="button" value="Imp" id="imp" /> Importo :
<input name="ReadOut" id="imp_text" type="Text" value=" "> <br>
<input type="button" value="Tes" id="tess" /> Card Tess :
<input name="readtess" id="tess_text" type="Text" value=" ">
<br>
<input type="button" value=" 1" onclick="NumPressed(1)" />
<input type="button" value=" 2" onclick="NumPressed(2)" />
<input type="button" value=" 3" onclick="NumPressed(3)" /> <br>
</form>
</body>
</html>

if (impo) and if (tess) just tests whether the element exists, which they do, so the value gets written to both of them because they both exist. In a desktop environment, you can't do what you're asking - you can give a textbox the focus, but once the user clicks on one of the buttons in order to select that number, the textbox no longer has the focus (because the button has it).
You need a separate way to maintain which textbox is currently selected, something like the snippet below. It will update the currently "selected" element both on the click of the Imp/Tes buttons and whenever either of the textbox gains focus (e.g. by mouse click or touch).
var impo = document.getElementById("imp_text");
var tess = document.getElementById("tess_text");
var current_input = impo;
impo.onfocus = function() {
current_input = impo;
}
tess.onfocus = function() {
current_input = tess;
}
document.getElementById('tess').onclick = function() {
current_input = tess;
tess.focus();
}
document.getElementById('imp').onclick = function() {
current_input = impo;
impo.focus();
}
function NumPressed(Num) {
current_input.value += Num;
}

How to check if at least one input is completed?

I have this sample:
link
CODE HTML:
<form class="add-patient">
<fieldset style="display: block;">
<label for="new_exam">New exam</label>
<input type="text" name="new_exam" id="new_exam" value="">
</fieldset>
<fieldset style="display: block;">
<label for="x_ray">X ray</label>
<input type="text" name="x_ray" id="x_ray" value="">
</fieldset>
<input type="button" class="btn btn-submit" onclick="sendForm();" value="Create report">
</form>
CODE JS:
function sendForm() {
var status_form = false;
$(".add-patient input").each(function(){
if($(this).val() == ""){
status_form = true;
}
});
console.log(status_form);
var createdBy = jQuery('#created_by').val();
if( status_form )
{
alert('Fill at least one field');
}else{
alert("now it's ok");
}
}
I want to do a check ... if an input is complete when displaying the message "it; s ok" ... otherwise displaying another message
probably means the code clearly what they want to do.
You can help me with a solution please?
Thanks in advance!

Use .filter to get the length of the input elements having value as ''
Try this:
function sendForm() {
var elem = $(".add-patient input[type='text']");
var count = elem.filter(function() {
return !$(this).val();
}).length;
if (count == elem.length) {
alert('Fill at least one field');
} else {
alert("now it's ok");
}
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
<form class="add-patient">
<fieldset style="display: block;">
<label for="new_exam">New exam</label>
<input type="text" name="new_exam" id="new_exam" value="">
</fieldset>
<fieldset style="display: block;">
<label for="x_ray">X ray</label>
<input type="text" name="x_ray" id="x_ray" value="">
</fieldset>
<input type="button" class="btn btn-submit" onclick="sendForm();" value="Create report">

show/hide div if input is 0 or default

I´m working in a payment gateway where the user Name the Price for my digital books. An input box (to text the price) and a "Pay now" button are displayed. BUT:
If the price is less than 0.50 the payment button disapear and the download button appear
If the user introduce a "," instead a "." a box is displayed (please, enter a valid number)
Here is the form with the input box:
<form id="hikashop_paypal_form" name="hikashop_paypal_form" action="https://www.paypal.com/cgi-bin/webscr" method="post">
<input type="hidden" name="cmd" value="_cart">
<input type="hidden" name="business" value="X" />
<input type="hidden" name="item_name_1" value="X" />
<input id="amount_1" name="amount_1" class="amount_1"/></form>
Pay Now button (it should be hiden if 1 is true)
<div id="PayNow" class="PayNow">
<input id="PayNow_button" type="submit" class="btn btn-primary" value="Pay now" name="" />
</div>
Download Now Button (it should be shown if 1 is true)
<div id="downloadNow" class="downloadNow">
Download now
</div>
Info box (It should be shown if 2 is true)
<div id="info" class="info">
Enter a valid number
</div>
And the question is: How can I do it?
I supose the solution passes by using javascript, but I don´t know how exactly... Thanks for you time...

alphabet validation on textbox in javascript using event keypress

I am trying to validate the form when any special characters or number press in the text box it should trigger an error as alert.
<html>
<head>
<script>
function demoMatchClick() {
var reg = new RegExp("[a-z]|[A-Z]");
if (document.form.name.value.match(reg)) {
alert("Successful match");
} else {
alert("Not a match");
}
}
</script>
</head>
<body >
<form onSubmit="alert('submit')" name="form">
<input type="text" name="name" value="name" onkeyup="demoMatchClick();"/>
<input type="submit" value="submit"/>
</form>
</body>
</html>

Replace your code with This:
function demoMatchClick(inputtxt) {
var letters = /^[A-Za-z]+$/;
var val = inputtxt.value.replace(/\s/g, '');
if (val.match(letters)) {
alert("Successful match");
} else {
alert("Not a match");
}
}
<html>
<body >
<form onSubmit="alert('submit')" name="form">
<input type="text" name="name" value="name" onkeyup="demoMatchClick(this);"/>
<input type="submit" value="submit"/>
</form>
</body>
</html>

<input type="text" name="name" value="name" pattern="[a-zA-Z]+" title="Letters only!"/>
Done. Demo

multiple forms with javascript

I am trying to show forms according to user input in the text box but it is showing it one time only...please help...
index.html:
<html>
<head>
<script type="text/javascript" src="demo1.js"></script>
</head>
<body>
<form name="su">
<input type="text" name="tt" onkeyup="javascript:toggleFormVisibility();" id="sub"/> </a>
</form>
<form id="subscribe_frm" style="display:none">
NAME:<input type="text" name="text">
EMAIL:<input type="text" name="text">
PASSWORD:<input type="text" name="text">
</form>
demo.js:
function toggleFormVisibility()
{
var txt = document.getElementById('sub').value;
for(var i=0;i<txt;i++)
{
var frm_element = document.getElementById('subscribe_frm');
var vis = frm_element.style;
vis.display = 'block';
}
}

A bit of a guess, but I think you are trying to create multiple copies of your form. Try this out:
http://jsfiddle.net/QnrM9/
JS
function toggleFormVisibility() {
var txt = document.getElementById('sub').value;
var neededChildren = txt.length - document.getElementById('form_container').children.length + 1;
for (var i = 0; i < neededChildren; i++) {
var frm_element = document.getElementById('subscribe_frm').cloneNode(true);
var vis = frm_element.style;
vis['display'] = 'block';
document.getElementById("form_container").appendChild(frm_element);
}
}
document.getElementById('sub').addEventListener('keyup', toggleFormVisibility);
HTML
<form name="su">
<input type="text" name="tt" id="sub" />
</form>
<div id="form_container">
<form id="subscribe_frm" style="display:none">NAME:
<input type="text" name="text" />EMAIL:
<input type="text" name="text" />PASSWORD:
<input type="text" name="text" />
</form>
</div>
