I've been looking around and didn't manage to resolve my case.
What I want is JS to change color based on user input value. w3schools have a library w3color.js and you simply call it by using div data-w3-color="ncs(3010-B10R)"
This is what I got:
<!DOCTYPE html>
<style>
div {
border: 3px solid #FFF;
padding-top: 30%;
padding-right: 30%;
padding-bottom: 30%;
padding-left: 30%;
}
</style>
<body>
<input type="text" id="myText" value="ncs code here..">
<button type="button" onclick="myFunction()">Try it</button>
<div data-w3-color="ncs(3010-B10R)">
</div>
<script>
function myFunction() {
document.getElementById("myText").value;
// change div data-w3-color to ncs code input
}
</script>
<!--
https://www.w3schools.com/colors/colors_ncs.asp
-->
<script src="https://www.w3schools.com/lib/w3color.js"></script>
<script>w3SetColorsByAttribute();</script>
</body>
</html>
I have given an id to the div and changing the data-w3-color attribute and calling the w3SetColorsByAttribute() function each time.
function myFunction() {
var color = document.getElementById("myText").value;
// change div data-w3-color to ncs code input
document.getElementById("ncsColor").setAttribute("data-w3-color", 'ncs('+ color +')')
w3SetColorsByAttribute();
}
div {
border: 3px solid #FFF;
padding-top: 30%;
padding-right: 30%;
padding-bottom: 30%;
padding-left: 30%;
}
<input type="text" id="myText" placeholder="ncs code here..3010-B10R">
<button type="button" onclick="myFunction()">Try it</button>
<div id="ncsColor" data-w3-color="ncs(3010-B10R)">
</div>

I was trying to make javascript take value from textbox and alert it, but it always pops up "Undefined". I tried grabing the value of selected items from combobox, but still shows undefined.
When I try using js in simple webpage, it works. Maybe something wrong with my code.
Note: I want the value to popup when "Schedule" button is clicked. Js will take value from txtbox and selected time value. But it does not..

Here is the hosted code on JSFiddle: https://jsfiddle.net/Lnt0crs8/1/
Any help would be appreciated.
Thanks.
Fetch textbox values in on click function call and try
function schedule()
{
var time = document.getElementById('txtScheduleInterval').value;
alert(time);
}
The variable time is now set only once, when the page is loaded.
It should be set whenever the schedule button is pressed.
So move the line var time = ... to a place within the schedule function:
function schedule()
{
var time = document.getElementById('txtScheduleInterval').value;
alert(time);
}
just add the below lines into the javascript schedule function
time = document.getElementById('txtScheduleInterval').value;
The value of the variable time is getting initialized while the page is getting loaded . While the page is been loaded the value return by document.getElementById('txtScheduleInterval').value is undefined as the input field txtScheduleInterval has no value in it. So while calling the function schedule you have to make sure that the variable time has the current value in txtScheduleInterval.
Hope this helps you..
You put your javascript which contain dom-operation before your html.
When your "var time = document.getElementById('txtScheduleInterval').value;" ran, it could not get your dom as your expectation. So the solution is either put your script after body or do dom-operation in your schedule function
fetch the values when the function is called. It should work!
function schedule()
{
time = document.getElementById('txtScheduleInterval').value;
timeOptions = document.getElementById("scheduleOptions").value;
alert(time);
}
I followed the examples that I found but for some reason clicking on the above div won't trigger a click on the below input. Can someone tell me where I'm going wrong?
$(document).on('click', '#uploader', function(event) {
$("#url").click();
});
#uploader {
width: 480px;
height: 100px;
line-height: 100px;
border: 2px dashed #443d66;
cursor: pointer;

If you need the click to focus on the #url element, use .focus() instead of .click():
$(document).on('click', '#uploader', function(event) {
$("#url").focus();
});
#uploader {
width: 480px;
height: 250px;
line-height: 250px;

I guess you want to open native file browser window on click. Check the snippet, there in an click handler attached to the input too.
You can use this for further processing.
I hope on click of div you want to show file upload window.
For that Convert type="text" to type="file" and it will work fine.
Working snippet:-
$(document).on('click', '#uploader', function(event) {
$("#url").click();
});
#uploader {
width: 480px;
height: 250px;
line-height: 250px;
border: 2px dashed #443d66;
cursor: pointer;
color: #777;
font-family: 'Arial';
font-weight: bold;
text-align: center;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<html>
<body>
<div id="uploader">
Click
</div>
<input type="file" name="url" id="url">
</body>
</html>
Note:-
Your code is working fine, but there is no click handler written to catch that event. So notting happening
You can assure by adding click handler to your code like below:-
$(document).on('click', '#uploader', function(event) {
$("#url").focus(); // you can apply .click() too
});
/* for click add the even handler like below
$('#url').click(function(){
$(this).val('Hey click worked!').focus();
});
*/
#uploader {
width: 480px;
height: 250px;
line-height: 250px;
border: 2px dashed #443d66;
cursor: pointer;
color: #777;
font-family: 'Arial';
font-weight: bold;
text-align: center;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<html>
<body>
<div id="uploader">
Click
</div>
<input type="text" name="url" id="url">
</body>
</html>
Instead of this
$(document).on('click', '#uploader', function(event) {
$("#url").click();
});
Use like this
$(document).on('click', '#uploader', function(event) {
$("#url").trigger('click);
});
Are you missing an click event for the #url element?
When triggering a click event for an element using .click() you have to define an actual click event for it.
$(document).on('click', '#uploader', function(event) {
$("#url").click();
});
$("#url").click(function(){
alert('asd');
});
This could be the only reason, unless the scripts aren't loaded properly, or you are getting some errors while running your JS.
See: JSFiddle
In case you want the click event to focus on your input element, you'd use .focus(), as described in a previous answer written by Alive to Die.
See: JSFiddle
Click & Focus, just modify few code
$('#uploader').on('click', function(event) {
$("#url").click().focus();
});
#uploader {
width: 480px;
height: 100px;
line-height: 150px;

I'm trying to create a program where the user will input some text in a field and when pressing "Start" the text will go to a paragraph but it will be shown backwards.
Trying to do this with Html,jquery and Css.
How can I do this?
Here's the Html:
<!DOCTYPE html>
<html id="head">
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script src="BackTalk.js"></script>
<link rel="stylesheet" type="text/css" href="BackTalk.css">
<title>BackTalk</title>
</head>
<body id="body">
<div id="Main">
<form>
<input id="input" type="number" value="Start">
<button id="input2" onclick="">Start</button>
</form>
</div>
<form id="frm">
<p id="para"></p>
</form>
</body>
</html>
And the $/javascript (Main part I need help with as you can see):
$(document).ready(function () {
$('#input2').click(function () {
});
});
Css (Don't know if needed):
#head {
}
#body {
background-image: url('stardust.png');
}
#Main {
width: 230px;
padding: 10px;
border: 1px double #ffffff;
border-radius: 10px;
margin: auto;
}
#frm {
width: 230px;
height: 500px;
padding: 10px;
border: 1px double #ffffff;
border-radius: 10px;
margin: auto;
}
#input {
border-radius: 10px;
}
#input2 {
border-radius: 10px;
}
Try this http://jsfiddle.net/Tushar490/th778nfs/
$('#input2').click(function () {
var value=$('#input').val();
console.log($('#para').text(value.split("").reverse().join("")));
});
Not sure if this is exactly what you're looking for:
$(document).ready(function () {
$('#startbutton').click(function () {
$('#para').text($('#input').val().split('').reverse().join(''));
});
});

Is there a quick way to create an input text element with an icon on the right to clear the input element itself (like the google search box)?
I looked around but I only found how to put an icon as background of the input element. Is there a jQuery plugin or something else?
I want the icon inside the input text element, something like:
--------------------------------------------------
| X|
--------------------------------------------------
Add a type="search" to your input
The support is pretty decent but will not work in IE<10
<input type="search">
Older browsers
If you need IE9 support here are some workarounds
Using a standard <input type="text"> and some HTML elements:
/**
* Clearable text inputs
*/
$(".clearable").each(function() {
const $inp = $(this).find("input:text"),
$cle = $(this).find(".clearable__clear");
$inp.on("input", function(){
$cle.toggle(!!this.value);
});
$cle.on("touchstart click", function(e) {
e.preventDefault();
$inp.val("").trigger("input");
});
});
/* Clearable text inputs */
.clearable{
position: relative;
display: inline-block;
}
.clearable input[type=text]{
padding-right: 24px;
width: 100%;
box-sizing: border-box;
}
.clearable__clear{
display: none;
position: absolute;
right:0; top:0;
padding: 0 8px;
font-style: normal;
font-size: 1.2em;
user-select: none;
cursor: pointer;
}
.clearable input::-ms-clear { /* Remove IE default X */
display: none;
}
<span class="clearable">
<input type="text" name="" value="" placeholder="">
<i class="clearable__clear">×</i>
</span>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
Using only a <input class="clearable" type="text"> (No additional elements)
set a class="clearable" and play with it's background image:
/**
* Clearable text inputs
*/
function tog(v){return v ? "addClass" : "removeClass";}
$(document).on("input", ".clearable", function(){
$(this)[tog(this.value)]("x");
}).on("mousemove", ".x", function( e ){
$(this)[tog(this.offsetWidth-18 < e.clientX-this.getBoundingClientRect().left)]("onX");
}).on("touchstart click", ".onX", function( ev ){
ev.preventDefault();
$(this).removeClass("x onX").val("").change();
});
// $('.clearable').trigger("input");
// Uncomment the line above if you pre-fill values from LS or server
/*
Clearable text inputs
*/
.clearable{
background: #fff url(http://i.stack.imgur.com/mJotv.gif) no-repeat right -10px center;
border: 1px solid #999;
padding: 3px 18px 3px 4px; /* Use the same right padding (18) in jQ! */
border-radius: 3px;
transition: background 0.4s;
}
.clearable.x { background-position: right 5px center; } /* (jQ) Show icon */
.clearable.onX{ cursor: pointer; } /* (jQ) hover cursor style */
.clearable::-ms-clear {display: none; width:0; height:0;} /* Remove IE default X */
<input class="clearable" type="text" name="" value="" placeholder="" />
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
The trick is to set some right padding (I used 18px) to the input and push the background-image right, out of sight (I used right -10px center).
That 18px padding will prevent the text hide underneath the icon (while visible).
jQuery will add the class "x" (if input has value) showing the clear icon.
Now all we need is to target with jQ the inputs with class x and detect on mousemove if the mouse is inside that 18px "x" area; if inside, add the class onX.
Clicking the onX class removes all classes, resets the input value and hides the icon.

Could I suggest, if you're okay with this being limited to html 5 compliant browsers, simply using:
<input type="search" />
JS Fiddle demo
Admittedly, in Chromium (Ubuntu 11.04), this does require there to be text inside the input element before the clear-text image/functionality will appear.
Reference:
Dive Into HTML 5: A form of Madness.
input type=search - search field (NEW) HTML5.
According to MDN, <input type="search" /> is currently supported in all modern browsers:
<input type="search" value="Clear this." />
However, if you want different behavior that is consistent across browsers here are some light-weight alternatives that only require JavaScript:
Option 1 - Always display the 'x': (example here)
Array.prototype.forEach.call(document.querySelectorAll('.clearable-input>[data-clear-input]'), function(el) {
el.addEventListener('click', function(e) {
e.target.previousElementSibling.value = '';
});
});
.clearable-input {
position: relative;
display: inline-block;
}
.clearable-input > input {
padding-right: 1.4em;
}
.clearable-input > [data-clear-input] {
position: absolute;
top: 0;
right: 0;
font-weight: bold;
font-size: 1.4em;
padding: 0 0.2em;
line-height: 1em;
cursor: pointer;
}
.clearable-input > input::-ms-clear {
display: none;
}
<p>Always display the 'x':</p>
<div class="clearable-input">
<input type="text" />
<span data-clear-input>×</span>
</div>
<div class="clearable-input">
<input type="text" value="Clear this." />
<span data-clear-input>×</span>
</div>
Option 2 - Only display the 'x' when hovering over the field: (example here)
Array.prototype.forEach.call(document.querySelectorAll('.clearable-input>[data-clear-input]'), function(el) {
el.addEventListener('click', function(e) {
e.target.previousElementSibling.value = '';
});
});
.clearable-input {
position: relative;
display: inline-block;
}
.clearable-input > input {
padding-right: 1.4em;
}
.clearable-input:hover > [data-clear-input] {
display: block;
}
.clearable-input > [data-clear-input] {
display: none;
position: absolute;
top: 0;
right: 0;
font-weight: bold;
font-size: 1.4em;
padding: 0 0.2em;
line-height: 1em;
cursor: pointer;
}
.clearable-input > input::-ms-clear {
display: none;
}
<p>Only display the 'x' when hovering over the field:</p>
<div class="clearable-input">
<input type="text" />
<span data-clear-input>×</span>
</div>
<div class="clearable-input">
<input type="text" value="Clear this." />
<span data-clear-input>×</span>
</div>
Option 3 - Only display the 'x' if the input element has a value: (example here)
Array.prototype.forEach.call(document.querySelectorAll('.clearable-input'), function(el) {
var input = el.querySelector('input');
conditionallyHideClearIcon();
input.addEventListener('input', conditionallyHideClearIcon);
el.querySelector('[data-clear-input]').addEventListener('click', function(e) {
input.value = '';
conditionallyHideClearIcon();
});
function conditionallyHideClearIcon(e) {
var target = (e && e.target) || input;
target.nextElementSibling.style.display = target.value ? 'block' : 'none';
}
});
.clearable-input {
position: relative;
display: inline-block;
}
.clearable-input > input {
padding-right: 1.4em;
}
.clearable-input >[data-clear-input] {
display: none;
position: absolute;
top: 0;
right: 0;
font-weight: bold;
font-size: 1.4em;
padding: 0 0.2em;
line-height: 1em;
cursor: pointer;
}
.clearable-input > input::-ms-clear {
display: none;
}
<p>Only display the 'x' if the `input` element has a value:</p>
<div class="clearable-input">
<input type="text" />
<span data-clear-input>×</span>
</div>
<div class="clearable-input">
<input type="text" value="Clear this." />
<span data-clear-input>×</span>
</div>
You could use a reset button styled with an image...
<form action="" method="get">
<input type="text" name="search" required="required" placeholder="type here" />
<input type="reset" value="" alt="clear" />
</form>
<style>
input[type="text"]
{
height: 38px;
font-size: 15pt;
}
input[type="text"]:invalid + input[type="reset"]{
display: none;
}
input[type="reset"]
{
background-image: url( http://png-5.findicons.com/files/icons/1150/tango/32/edit_clear.png );
background-position: center center;
background-repeat: no-repeat;
height: 38px;
width: 38px;
border: none;
background-color: transparent;
cursor: pointer;
position: relative;
top: -9px;
left: -44px;
}
</style>

I've created a clearable textbox in just CSS. It requires no javascript code to make it work
below is the demo link
http://codepen.io/shidhincr/pen/ICLBD
Since none of the solutions flying around really met our requirements, we came up with a simple jQuery plugin called jQuery-ClearSearch -
using it is as easy as:
<input class="clearable" type="text" placeholder="search">
<script type="text/javascript">
$('.clearable').clearSearch();
</script>
Example: http://jsfiddle.net/wldaunfr/FERw3/
If you want it like Google, then you should know that the "X" isn't actually inside the <input> -- they're next to each other with the outer container styled to appear like the text box.
HTML:
<form>
<span class="x-input">
<input type="text" class="x-input-text" />
<input type="reset" />
</span>
</form>
CSS:
.x-input {
border: 1px solid #ccc;
}
.x-input input.x-input-text {
border: 0;
outline: 0;
}
Example: http://jsfiddle.net/VTvNX/
Change the text box type as 'search' in the design mode or
<input type="search">
EDIT: I found this link. Hope it helps. http://viralpatel.net/blogs/2011/02/clearable-textbox-jquery.html
You have mentioned you want it on the right of the input text. So, the best way would be to create an image next to the input box. If you are looking something inside the box, you can use background image but you may not be able to write a script to clear the box.
So, insert and image and write a JavaScript code to clear the textbox.
Use simple absolute positioning - it's not that hard.
jQuery:
$('span').click(function(){
$('input', $(this).parent()).val('');
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div style="position:relative; width:min-content;">
<input>
<span style="position:absolute;right:10px">x</span>
</div>
<div style="position:relative; width:min-content;">
<input>
<span style="position:absolute;right:10px">x</span>
</div>
<div style="position:relative; width:min-content;">
<input>
<span style="position:absolute;right:10px">x</span>
</div>
Vanilla JS:
var spans = document.getElementsByTagName("span");
function clickListener(e) {
e.target.parentElement.getElementsByTagName("input")[0].value = "";
}
for (let i = 0; i < spans.length; i++) {
spans[i].addEventListener("click", clickListener);
}
<div style="position:relative; width:min-content;">
<input>
<span style="position:absolute;right:10px">x</span>
</div>
<div style="position:relative; width:min-content;">
<input>
<span style="position:absolute;right:10px">x</span>
</div>
<div style="position:relative; width:min-content;">
<input>
<span style="position:absolute;right:10px">x</span>
</div>
jQuery Mobile now has this built in:
<input type="text" name="clear" id="clear-demo" value="" data-clear-btn="true">

Something like this??

You can do with this commands (without Bootstrap).
Array.from(document.querySelectorAll('.search-field')).forEach(field => {
field.querySelector('span').addEventListener('click', e => {
field.querySelector('input').value = '';
});
});
:root {
--theme-color: teal;
}
.wrapper {
width: 80%;
margin: 0 auto;
}
div {
position: relative;
}
input {
background:none;
outline:none;
display: inline-block;
width: 100%;
margin: 8px 0;
padding: 13px 15px;
padding-right: 42.5px;
border: 1px solid var(--theme-color);
border-radius: 5px;
box-sizing: border-box;
}
span {
position: absolute;
top: 0;
right: 0;
margin: 8px 0;
padding: 13px 15px;
color: var(--theme-color);
font-weight: bold;
cursor: pointer;
}
span:after {
content: '\2716';
}
<div class="wrapper">
<div class="search-field">

<span></span>

Here's a jQuery plugin (and a demo at the end).
http://jsfiddle.net/e4qhW/3/
I did it mostly to illustrate an example (and a personal challenge). Although upvotes are welcome, the other answers are well handed out on time and deserve their due recognition.
Still, in my opinion, it is over-engineered bloat (unless it makes part of a UI library).
I have written a simple component using jQuery and bootstrap.
Give it a try: https://github.com/mahpour/bootstrap-input-clear-button
Using a jquery plugin I have adapted it to my needs adding customized options and creating a new plugin. You can find it here:
https://github.com/david-dlc-cerezo/jquery-clearField
An example of a simple usage:
<script src='http://code.jquery.com/jquery-1.9.1.js'></script>
<script src='http://code.jquery.com/ui/1.10.3/jquery-ui.js'></script>
<script src='src/jquery.clearField.js'></script>
<link rel="stylesheet" href="http://code.jquery.com/ui/1.10.3/themes/smoothness/jquery-ui.css">
<link rel="stylesheet" href="css/jquery.clearField.css">
<table>
<tr>
<td><input name="test1" id="test1" clas="test" type='text'></td>
<td>Empty</td>
</tr>
<tr>
<td><input name="test2" id="test2" clas="test" type='text' value='abc'></td>
<td>Not empty</td>
</tr>
</table>
<script>
$('.test').clearField();
</script>
Obtaining something like this:
No need to include CSS or image files. No need to include that whole heavy-artillery jQuery UI library. I wrote a lightweight jQuery plugin that does the magic for you. All you need is jQuery and the plugin. =)

I have the following code, and the javascript console in chrome says "Can't read innerHTML property of null. Why does document.getElementById('display') turn up empty handed?

showmsg("Your browser doesn't support WebSockets. Try Google Chrome.");
}

Move your script-section down to the bottom of the page. Otherwise it is executed before the page has been loaded.
Btw: Putting scripts at the bottom of your page is even a "best practice" and recommended by Google, Yahoo & Co
You're calling showmsg before the whole page (and hence the display div) is loaded. Hence the error. Call it from onload and it'll work.
Add this function to the <head>
function handleLoad()
{
document.getElementById("username").focus()
if("WebSockets" in window){
pass;
}else{
showmsg("Your browser doesn't support WebSockets. Try Google Chrome.");
}
}
and call it from onload
<body onload="handleLoad()">
Put your script tag at the end of the document:.
In your case the page has not been completely parsed into DOM tree, but your script executes anyway:
<body onload="document.getElementById('username').focus()">
<input type="text" id="username" />
<div id="container">
<div id="display"></div>
<div id="onlineusers"></div>
<div class="clearfix"></div>
</div>
<div id="container2">
<input type="text" id="inputline" length="55" />
<input type="button" id="sendbutton" value="Send" />
</div>
<script type="text/javascript">
function showmsg(str){
var display = document.getElementById('display');
display.innerHTML += "<p>" + str + "</p>";
}
if("WebSockets" in window){
pass;
}else{
showmsg("Your browser doesn't support WebSockets. Try Google Chrome.");
}
</script>
</body>
This is also considered a good practice for performance reasons:
