I've been looking thru the docs and another question that was close to what I needed for help with the jRate star rating jQuery plugin, but I was not able to get the output I was looking for. What I am looking to do is to get an output of the numerical rating value when I click a button.
With this html :
<div id="ratingContainer">
<div id="currentValue" style="width: 70px; height: 70px; border: 1px solid black; background-color: blue; color: white" >Rating value</div>
<input type="button" id="ratingClicker" value="get rating!" onclick="getRatingValue()" />
</div>
and this javascript :
function getRatingValue(){
$(document).ready(function(){
$('ratingContainer').jRate({
onSet: function(rating){
$('ratingValue').text(rating);
}
})
});
}
function getSimpleStarRatingHtml(){
$(document).ready(function() {
$("#ratingContainer").jRate({
width: 60,
height: 60,
startColor: '#3366FF',
endColor: '#9966FF'
});
});
}
The getSimpleStarRatingHtml() function populates the empty stars in the ratingContainer div when the user pulls a select dropdown.
The getRatingValue code was cribbed from the other StackOverflow question I linked to.
I realize this is probably a basic jQuery Q; I'm a little bit of a noob with it. Thanks.
Update
The code below does give me the output for the rating value I want, but does not allow me to set any options for the appearance of the stars (height, color, etc):
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8"/>
<link rel="stylesheet" href="//code.jquery.com/ui/1.11.4/themes/smoothness/jquery-ui.css">
<script type="text/javascript" src="javascript/jquery-1.11.2.js"></script>
<script type="text/javascript" src="javascript/jRate.js"></script>
<script src="//code.jquery.com/ui/1.11.4/jquery-ui.js"></script>
<script type="text/javascript">
function createJrate(){
$('#rating').jRate({
onChange: function(rating){
$('#ratingValue').text(rating);
}
});
}
</script>
<style>
#rating{
width: 300px;
height: 140px;
border: 1px black solid;
}
</style>
</head>
<body>
<h1>test</h1>
<input type="button" value="create rating" onclick="createJrate()" style="margin-bottom: 15px"/>
<div id="rating"></div><div id="ratingValue"></div>
</body>
</html>
Have tried a bunch of variations, like adding the rating function after the close bracket that ends the options, tried tying the $('#ratingValue').jRate() to a var, and then calling the function, as in jRate.change(function(){// stuff in here});.
Any other ideas you may have?
thanks
If your logic works and you're just looking to change the styling, have you considered simply overriding the standard CSS for the script to have it render with the colors and formatting that you'd prefer?
was able to get it working by defining the jRate obj this way...
$('#rating').jRate({
onChange: function(rating){
$('#ratingValue').text("rating " + rating);
},
startColor: 'blue',
endColor: 'blue',
width: 50,
height: 50
});

JQuery beginner here. I'm trying to get a group of divs to change from red to blue when I click on them. When I click them again, I want the divs to change back to red. I tried using jQuery's animate() method (with the jQuery color plugin) to change the div's color. However, the code below only partially works.
$(document).ready(function(){
$("div").click(function() {
$("div").each(function() {
if (this.style.color !== "blue") {
$(this).animate({
color:'blue'
},1000);
} else {
this.style.color = "red";
}
});
});
});
When I click a div, the if statement works fine. The divs change to blue. However, when I click a div again, the divs don't change back to red. The else statement doesn't seem to work. Any ideas on my mistake? The else statement works when I replace $(this).animate({...}) with this.style.color = "blue"; which so I think I'm doing something wrong with the animate() method.
Here is the HTML file
<!DOCTYPE html>

font-weight: bolder;

}

Just don't use blue or red color codes. It will get converted to RGB code.
For example this.style.color will be RGB(0,0,255) not blue so your expression always returns true no matter what color is it.
I create this example in different color mode for you to take a look https://jsfiddle.net/3tpncgr1/1/
Anyway, if you want to have special logic for particular color then keep using this approach. Otherwise, use class name instead of color code to determine. Because browsers always return rgb value for color attribute
I would manage it by using a active class to control the states.
In that case I would succes changing
$(document).ready(function(){
$("div").click(function() {
$.each( $(this).parent().children("div"),function() {
if (!$(this).hasClass('active')) {
$(this).addClass('active');
$(this).animate({
color:'blue'
},1000);
} else {
$(this).removeClass('active');
this.style.color = "red";
}
});
});
});

I'm using Background Check JS to try and get some text on my website to change based on the background being light or dark. I can't get it to work on my site to made a minimal replica of it and still no dice:
<html>
<head>
<style>
.background--light {
color: black;
}
.background--dark {
color: white;
}
.background--complex {
color: gray;
}
</style>
<script src="https://code.jquery.com/jquery-1.10.2.js"></script>
<script src="http://www.kennethcachia.com/background-check/scripts/background-check.min.js"></script>
<script>
document.addEventListener('DOMContentLoaded', function () {
BackgroundCheck.init({
targets: '.target',
});
});
</script>
</head>
<body>
<img src="http://www.kennethcachia.com/background-check/images/6.jpg">
<div style="position: fixed; top: 65%;" class="target">Why not white?</div>
</body>
</html>
Also sometimes an "CanvasRenderingContext2D': The canvas has been tainted by cross-origin data." Error pops up in this demo sometimes?
I may have missed something trivial in this demo but I can't get it to work at all on my "full" version I'm trying to write.
Can anyone suggest me a solution please? I've been trying half an hour to get jQuery ready and working for my Visual Studio but it does not work. I can't really be specific because i also don't know why.
<script>
$(document).ready(function () {
$("button").click(function () {
$("#square").animate({ left: '500px' }, slow);
});
});
</script>
<style>
#square{
border: solid; border-color: aqua; border-width: 1px; background-color: skyblue; width: 125px; height: 125px; text-align:center;
}
</style>
<body>
<div id="square">Focus on me!</div>
<div> <button>Click me</button> </div>
You have to add jquery to your page. You can add jQuery in two ways :
Download the jQuery library from jQuery.com
Include jQuery from a CDN, like Google
The jQuery library is a single JavaScript file, and you reference it with the HTML tag :
<head>
<script src="jquery-1.11.3.min.js"></script>
</head>
And for CDN :
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
</head>
then write your code :
$(document).ready(function(){
alert("Hello there!")
});
Add this piece of code above the closing body tag.
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
Now you have successfully added jQuery!
The JSTween library doesn't seem to perform a simple animation pulled from the library's tutorial. Using the following code, the alert box will show up after the allotted 1 second duration, but no animation will take place.
I must have set up the library wrong somehow, but I can't see the problem.
<html>
<head>
<style type="text/css">
#box
{
width: 16px;
height: 16px;
}
</style>
<script type="text/javascript" src="jquery-1.10.1.js"></script>
<script type="text/javascript" src="jstween-1.1.js" ></script>
<script type="text/javascript" src="jstween-1.1.min.js" ></script>
<script type="text/javascript">
function animate()
{
$('#box').tween({
width:{
start: 16,
stop: 200,
time: 0,
units: 'px',
duration: 1,
effect:'easeInOut',
onStop: function(){ alert( 'Done!' ); }
}
}).play();
}
</script>
</head>
<body>
<div id="box">
<img src="image.png" onClick="animate()" />
</div>
</body>
</html>
Additional info: using Safari on 10.7.5. Code does not work in Chrome or Firefox either.
For anyone who may read this in the future, I discovered the problem: the CSS element #box needs position: relative; as an attribute, otherwise the browser will hold the element in place by default.
I am trying to get the below html code to work and can't figure it out. I do not think the domready event is being fired and can't figure out why.
<!DOCTYPE html>
<head>
<meta http-equiv="content-type" content="text/html; charset=utf-8"/>
<style>
.slider {
background: #CCC;
height: 16px;
width: 200px;
}
.slider .knob {
background: #000;
width: 16px;
height: 16px;
}
</style>
<script type="text/javascript">
window.addEvent('domready', function(){
var slider = $('slider');
new Slider(slider, slider.getElement('.knob'), {
range: [0, 100],
initialStep: 100, steps: 11, wheel: true,
onChange: function(value){
alert(value);
}
});
});
</script>
</head>
<body>
<div id="slider" class="slider">
<div class="knob"></div>
</div>
</body>
</html>
I just want to have a slider on my webpage and can't use html 5 because of browser restrictions. What is the simplest slider I can use to do this?
First problem that I see is in the var slider = $('slider'); statement.
You need to change it to var slider = $('#slider'); or var slider = $('.slider'); depends on if you want to access it via ID or CLASS name.
You can also use http://nivo.dev7studios.com/ as a slider which is a good jQuery plugin that I've been using.
Rather than using window.addEvent();, why not use
$(function(){
// your code here.
});
That uses jQuery's on ready event, so you can be sure it will fire on document ready
And as stated by Odinn above, you are using $('slider'), which means that jquery is looking for an element that is . you need to specifiy if you are searching for an ID $('#slider') or by class $('.slider');
Other than that, i would keep your console open to look for any errors and post those. Hope that helps.
