I am making my own WYSIWYG editor. But i can't make any text bold with the execcommand function. I am using the next code:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<title>Untitled Document</title>
<script type="text/javascript">
function loadWysiwyg() {
if(window.navigator.appName == "Microsoft Internet Explorer") {
reactioneditor.document.designMode = "on";
} else {
document.getElementById('reactioneditor').contentDocument.designMode = "on";
}
}
function make_bold() {
document.getElementById("reactioneditor").contentWindow.document.execCommand("bold", false, null);
}
</script>
</head>
<body onload="loadWysiwyg();">
<iframe id="reactioneditor" style="border: 1px solid #CCC;width: 100%; height: 200px;"></iframe>
<button id="makebold" onclick="make_bold();">Maak bold</button>
</body>
</html>
I readed multiple tutorials but with no effect, i don't now how i can fix it.
Is there anyone who can?
Your exact code works for me in IE, Firefox, and Chrome. I wrote some text into the iFrame, selected it, and clicked the button. Are those the steps you are taking? Are you getting any errors?

I am having an issue where the Screen Reader is not reading the text that changes within aria-live section in FireFox.
This is a simple example for a page where in chrome the Screen Reader reads the changes as they come in and in FireFox it does not:
<div aria-live="assertive" id="moo">
</div>
<script>
let i = 0;
setInterval(() => {
document.getElementById('moo').innerText = 'moo' + i++
}, 2000)
</script>
Am I doing something wrong? Is there another way to announce changes when they come in besides for aria-live that people use with Firefox?
I tested on Mac-Firefox-VoiceOver (it works on Mac-Chrome-VoiceOver)
Current firefox version: 83.0 (64-bit)
Firefox Nightly version：85.0a1 (2020-11-29) (64-bit)
In the latest Nightly version, the combination of aria-live on firefox + voiceOver is fixed! 🎉 Hooray!

As the title suggest, I'm trying to change my css background-color using javascript function. To simplify the problem, I write a new code here.
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>Potato</title>
<style>
#item {
background-color:blue;
color:red;
}
</style>
<script type="text/javascript">
function changeBG(id,color) {
var id = id;
var color = color;
document.getElementById(id).style.background-color = color;
}
</script>
</head>
<body>
<script type="text/javascript">changeBG(item,green)</script>
<div id="item">I am a potato</div>
</body>
</html>
The default background-color is red (as suggested by CSS), then I want to change it to green before I print it. But the code doesn't work. I don't know where the mistake is.
First item needs to be made first:
<div id="item">I am a potato</div>
<script>
//...stuff....
</script>
Then we need to use strings:
changeBG("item","green")
And finally in JavaScript we say backgroundColor other than background-color.
#media print {
#item {
background-color:green;
}
}
Include this in your css. This will solves your problem while printing.
All css properties in javascript are camelCased rather than spinal-cased
document.getElementById('youElement').style.backgroundColor = 'color';
Use jQuery
$("#item").css("background-color", "green");
Documentation
Or pure JavaScript
document.getElementById("item").style.backgroundColor = "green";
Documentation
the add class is not working even if it is in document ready. I tried both with document ready and without it. it is not working but alert is working.
var $jbanner = jQuery.noConflict(true);
if ($jbanner(window).width() < 1200) {
alert("Less than 1200");
$jbanner("#wad").addClass("hide");
}
other code
var $jbanner = jQuery.noConflict(true);
$jbanner(document).ready(function () {
if ($jbanner(window).width() < 1200) {
alert("Less than 1200");
$jbanner("#wad").addClass("hide");
}
})
With document ready function even the alert box is not working. is it conflicting with other jquerys in the page.
#wad is an image
<img id="wad" src="images/banner.jpg"/>
thanks
ok this should be pretty easy, but not working for me. I just pasted what i am trying to do in a separate html file. but still not working, any help is appreciated.

I am just trying to create a floating banner ad. that hides for smaller screen sizes.
Try to without jbanner.
$("#wad").addClass("hide");
The following works well in Internet Explorer and Chrome, but NOT in Firefox.
The idea is to change the background of the parent body after every click within the iframe.
Note that Firefox somehow knows to set the blue background initially.
index.html
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head><script>
function polling() {
if (window.iframeId.change) document.body.style.background = 'red';
if (!window.iframeId.change) document.body.style.background = 'blue';
setTimeout(polling, 1000); }
</script></head>
<body onload="polling();">
<iframe id="iframeId" src="frame.html" style="width:100px; height:100px;"></iframe>
</body>
</html>
frame.html
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head><script>var change=false;</script></head>
<body style="background:yellow;" onclick="change=!change;"></body>
</html>
This is how I could make it work:
index.html
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<script>
function polling() {
if (window.frames['theIframe'].change) {
document.body.style.background = 'red';
}
else {
document.body.style.background = 'blue';
}
setTimeout(polling, 1000);
}
</script>
</head>
<body onload="polling();">
<iframe id="iframeId" src="frame.html" name="theIframe" style="width: 100px; height: 100px;"></iframe>
</body>
</html>
frame.html
<!DOCTYPE HTML >
<html>
<head>
<script>
var change = false;
function load() {
document.onclick = doClick;
}
function doClick() {
change = !change;
}
</script>
</head>
<body style="background: yellow;" onload="load()"></body>
</html>
I want to update the timestamp on useronline database only when people aren't idle (keyboard mouse active for some time-I am using a jquery plugin for that) The problem for me is that I can't clear the interval for the function so in my test script below, when it starts counting it never stops and even when active again it starts another counter so that its like its counting twice as fast. How am I supposed to stop that timer? Its like the counter has never been started when its idle- so it can't find it to stop it.
In the real script the counter will be $.get()-ing the php that updates the mysql table. For that reason i'm using intervals, or it would get on every mouse move right? and that would be loading the server.
http://jsbin.com/uleza5 to test just don't move mouse for 6 seconds then see the idle text, then move the mouse and it will start counting; after 6 seconds it will go idle again when inactive.
