Am using the below script to change the color of the script but showing 'font color="red">Hello world /font> like this.Is any possible way to change the alert text color..
<html>
<head>
<title>JavaScript String fontcolor() Method</title>
</head>
<body>
<script type="text/javascript">
var str = new String("Hello world");
alert(str.fontcolor( "red" ));
</script>
</body>
</html>
No. alert() accepts a string and renders it using a native widget. There is no provision to style it.
The closest you could get would be to modify the HTML document via the DOM to display the message instead of using an alert().
You can use JQuery to resolve your Problem
<html>
<head>
<meta charset="utf-8" />

$(function() {

$( this ).dialog( "close" );
}
}});
});
</script>
</head>
<body>
<div id="dialog-message" title="My Dialog Alternative">
<p style='color:red'> Hello world </p>
</div>

Hope this help :

So I wanted to make a webpage in which on button click, the background color changes.
Its showing TypeError on loading in browser but its working fine after pasting same JavaScript on console.
Code snippet
var colors = ["#0af5fa", "#0ab1fa", "#0a3efa", "#560afa", "#b70afa", "#fa0ad9", "#fa0a65", "#fa0a1e", "#fa5e0a", "#facc0a", "#cbfa0a", "#69fa0a", "#0afa1b", "#0afa77", "#0afae5", "#0a8efa"];
var flag = 0,
blinkCount = 0;
function blink() {
if (blinkCount == 15) {
blinkCount = 0;
blink();
} else {
var h1 = document.querySelector("h1");
var body = document.querySelector("body");
h1.style.color = colors[blinkCount];
body.style.background = colors[blinkCount];
blinkCount++;
}
}
var button = document.querySelector("button");
button.addEventListener("click", blink);
button {
width: 50%;
height: 100px;
background: black;
margin-top: 300px;
margin-left: 300px;
}
h1 {
color: #0af5fa;
}
body {
background: #0af5fa;
}

You're running the script before the document has been fully parsed - see how the <script> is above the <body> and its <button>?
Either give the script tag the defer attribute:
<script defer src="..
Or move it to the bottom of the body:
</div>
<script src="../JavaScript/ex153.js"></script>
</body>
</html>
Or wrap the whole script in a DOMContentLoaded listener:
document.addEventListener('DOMContentLoaded', function() {
var colors;
// other code
});
I'm a beginner so I'm sorry for a stupid question. The matter is I can't add div "title" inside of div "app" using JS. Help me please.
<!DOCTYPE HTML>
<html>
<head>
<meta charset = "utf-8">
<meta name = "description" content = "Field v.1">
<title> Field v.1 </title>
<style>
.app{
background-color: 'black';
}
.title{
background-color: 'green';
}
</style>
</head>
<body>
<div class = "app">
</div>
<script>
var app = document.querySelector('.app')
var title = document.createElement('div')
title.className = 'title'
title.innerHTML = "BREAKING NEWS"
app.appendChild(title);
</script>
</body>
</html>
The JavaScript works perfectly. Here's the result of your JS:
<div class="app">
<div class="title">BREAKING NEWS</div>
</div>
However, there's a small problem with your CSS. Do not quote CSS values!. It should be:
.app{
background-color: black;
}
.title{
background-color: green;
}
<!DOCTYPE HTML>
<html>
<head>
<meta charset = "utf-8">
<meta name = "description" content = "Field v.1">
<title> Field v.1 </title>
<style>
.app{
background-color: black;
}
.title{
background-color: green;
}
</style>
</head>
<body>
<div class = "app">
</div>
<script>
var app = document.querySelector('.app')
var title = document.createElement('div')
title.className = 'title'
title.innerHTML = "BREAKING NEWS"
app.appendChild(title);
</script>
</body>
</html>
There is nothing wrong with your JS code.
You can see your working code in this Codepen:
https://codepen.io/kmpkt/pen/bvYwpm
But there is a error in your CSS code. CSS values may not be quoted:
background-color: black;
I want to open a new window/tab, put some HTML in the document, then bring up the browser print dialog to print that new window. I am using the following to accomplish this:
var w = window.open();
w.document.write(html);
w.document.close();
w.focus();
w.print();
w.close();
HTML:
<body>
<img src='url1' />
<img src='url2' />
<img src='urln' />
</body>
This all works, the window pops up, and the print dialog is shown for the new page and prints all images fine. However, for some reason, some of images are printing, and instead the image alt message is printed.
There are lots of images, and they are dynamically generated on the server side (which takes about 1 second to load each).
What needs to be done to make sure all images are loaded and printed?
This happens in IE and Firefox that I've confirmed. I appreciate any help.
Try to use a JS library that detect when images have been loaded.
You can use it like this:
<script src="https://npmcdn.com/imagesloaded#4.1/imagesloaded.pkgd.min.js"></script>
<script type="text/javascript">
imagesLoaded(document.body, function() {
window.print();
});

here is my problem. I have the code that you see below. Why it doesn't work like it does here: http://jsfiddle.net/e6kaV/33/ ?
There is the error that is shown to me:

I put it in the <head> but you can put it anywhere, as long as it's before the code that uses $ ($ is jQuery).
You should add jquery before you can use it. Here is the working example. I have just removed the script tag of jquery from bottom and placed it before other scripts.
Here is the pen http://codepen.io/anon/pen/xOzjWg
$(".pane-launcher").click(function () {
// Set the effect type
var effect = 'slide';
// Set the options for the effect type chosen
var options = { direction: 'up' };
// Set the duration (default: 400 milliseconds)
var duration = 700;
$('.pane.active, #'+this.id+'-pane').toggle(effect, options, duration).toggleClass('active');
});

Because the element doesn't exist in the DOM on page load, you need to use an event delegate, such as on:
$(function () {
$("body").on("click", ".class1", function () {
alert("The div was clicked.");
});
});
Or for pre-1.7 jQuery, use delegate:
$(function () {
$("body").delegate(".class1", "click", function () {
alert("The div was clicked.");
});
});
click only binds handlers to elements that were present in the DOM when you called it.
Instead, use the jQuery on method:
$(document).ready(function () {
$("body").on("click", ".class1", function () {
alert("The div was clicked.");
});
});
You will need to re-apply the click handler to the newly created divs.
