I just want to trigger an event like release or change event with a jQuery knob. According to documentation, it should work with this:
<script>
$(".dial").knob({
'release' : function (v) { /*make something*/ }
});
</script>
In my code i have something very similar:
<html>
<head>
<meta charset="utf-8">
<link rel="icon" href="img/favicon.png">
<title>Knobs</title>
<link rel="stylesheet" type="text/css" href="css/style.css">
<script type="text/javascript" src="js/jquery-1.11.2.min.js"></script>
<script type="text/javascript" src="js/text.js"></script>
<script type="text/javascript" src="js/jquery.knob.min.js"></script>
</head>
<body>
<div class="knobBar">
<input id="gain1" class="knob"
data-angleOffset=-125
data-angleArc=250
data-bgColor="#262626"
data-fgColor="#00ff00"
data-rotation="clockwise"
value="0"
data-min="0"
data-max="100"
data-lineCap="round"
data-displayPrevious="true"
data-width="5%"
data-font="Advanced LED Board-7">
</body>
And I put this at the end of the html file:
<script>
//Listeners for Knobs changes
$(function () {
$('#gain1').knob({
'release': function (v) {
console.log(v);
gain_1.gain.value = v / 100;
}});
})
</script>
I just don't get it to work. It doesn't print anything to console, so obviously is not triggering the function.

There are two versions of code. The first version is there is a main page containing an iframe and dialog <div>. The iframe will load the dia.html into the parent <div id="popdiv"> and fire it as a dialog. The dialog itself will initiate a Datepicker with elem.datepicker();.
The second version is just the ideal version for what I want which is an iframe fire the parent main page dialog and have a Datepicker running. But this approach cannot load the dia.html page into the <div id="popdiv"> which is not as handy.
My question:
Why is that when I want to select the element$('#myInput', window.parent.document) in the dia.html, I need to add window.parent.document after selector?
I try to figure it out by checking the html code in development tools. But I had no idea why it is required. How does query Dialog work?
How to make the elem.datepicker(); inside the dia.html work inside the dialog if I want to use the .load('dia.html') approach? What was the reason it didn't work?

I am trying to make a markdown editor, but I am having an issue with my IFrame. It sets the IFrame source to about:blank to clear the screen, but it doesn't write to the iframe again until a key is pressed. How can I fix this?

Update
You could use jquery on key up function? So after the cuser has finished typing it will update?
$( "#target" ).keyup(function() {
#update iframe code here
});
You could refresh the iframe every 30 seconds?
<script>
window.setInterval("reloadIFrame();", 30000);
function reloadIFrame() {
document.frames["framename"].location.reload();
}
</script>
I always save this peace of code. It's great.
I downloaded this jquery plugin: http://harshen.github.io/jquery-countdownTimer/
specifically to use the Reverse countdown to zero from time set to only minutes timer.
I am pretty sure I followed the instructions correctly but the plugin does not work. I have never used jQuery or plugins before, so I'm not sure if I am missing something or just doing something completely wrong (or both).
My Javascript test alert does run.
I will attach my code for you all to look at. Not sure if it has to do with my file paths, but I've attached an image of that as well. Please tell me what could be causing the problem and how to fix. Thank you.

Hi so I'm trying to like a javascript file to my web page, when it was in the HTML file it worked fine, but I won't to neaten it up a little by putting the JS in a different file
HTML:
<head>
<meta charset="utf-8" />
<title>Digital Canvas Web Designs</title>
<link rel="stylesheet" href="/CSS/Template.css"/>
<link rel="stylesheet" href="/CSS/news.css"/>
<link rel="shortcut icon" href="images/tablogo.ico" > <!-- tab logo generated at http://www.favicongenerator.com/ -->
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script src="Javascript/newshide.js" type="text/javascript"></script>
</head>
<body>
and Javascript:
<script type="text/javascript">
$(document).ready(function(){
$("#show").click(function() {
$("#hidden").show();
});
$("#hide").click(function() {
$("#hidden").hide();
});
});
</script>
And the part of HTML where the JS should work.
<span id="show">more>></span>
<p id="hidden" hidden>COOL STORY BRO
<span id="hide">less</span> </p>
wrap all into document.ready
<script type="text/javascript">
$(document).ready(function(){
$("#show").click(function() {
$("#hidden").show();
});
$("#hide").click(function() {
$("#hidden").hide();
});
});
</script>
Also: you have another bug, change the last script for:
<script src="Javascript/newshide.js" type="text/javascript"></script>
Docs
Change this
<script src=".\Javascript\newshide.js" type="text/javascript"></script>
To this
<script src="Javascript/newshide.js" type="text/javascript"></script>
I checked many times, but I have no idea why the jQuery wont work. It works in jsfiddle!
html:
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>Josue Espinosa</title>
<link href="style.css" rel="stylesheet" type="text/css">
<script src="animate.js"></script>
<script src="http://code.jquery.com/jquery-latest.min.js"
type="text/javascript"></script>
</head>
<body>
<div id="menu">
</div>
</body>
</html>
css:
#menu{
width:15px;
height:200px;
background:red;
}
jquery:
$('#menu').hover(function(){
$("#menu").stop().animate({width : "300px"});
});
It seems like problem lies here:
<script src="animate.js"></script>
<script src="http://code.jquery.com/jquery-latest.min.js" type="text/javascript"></script>
Your animate.js goes before jquery loads
You need to either wrap your jquery code in $(function () {}) or (preferred) move the code to just before </body>.
Since the other answers didn't seem to work out for you, I'm going to take a stab at a suggestion.
I'm guessing that you're initializing your JavaScript in a location where the element you're adding the event listener to isn't available yet. Here is a solution to this problem.
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>Josue Espinosa</title>
<link href="style.css" rel="stylesheet" type="text/css">
<script src="http://code.jquery.com/jquery-latest.min.js" type="text/javascript"></script>
<script src="animate.js"></script>
</head>
<body>
<div id="menu">
</div>
<script type="text/javascript">
$('#menu').hover(function () {
$("#menu").stop().animate({ width: "300px" });
});
</script>
</body>
</html>
In this example, the JavaScript is immediately below the element you're adding the listener to, so it is guaranteed to be available in the DOM.
Alternatively, you can wrap your JS around an event to fire after the document is ready. Here is an example:
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>Josue Espinosa</title>
<link href="style.css" rel="stylesheet" type="text/css">
<script src="http://code.jquery.com/jquery-latest.min.js" type="text/javascript"></script>
<script src="animate.js"></script>
<script type="text/javascript">
$(document).ready(function () {
$('#menu').hover(function () {
$("#menu").stop().animate({ width: "300px" });
});
});
</script>
</head>
<body>
<div id="menu">
</div>
</body>
</html>
It is also important to note the sequence of the JavaScript elements.
