I just start to use JQuery and I want to add li element in my HTML when I click on a button.
My Html code :
<!DOCTYPE html>
<html lang="fr">
<head>
<meta charset="utf-8">
<link rel="stylesheet" href="css/style.css">
<script type="text/javascript" src="js/index.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
</head>
<body>
<div class="filtres">
<input id="filtre1" type="button" value="filtre 1" onclick="test()">
</div>
<div id="liste">
<ul>
<li>Bonjour</li>
</ul>
</div>
</body>
</html>
And my js file :
function test() {
console.log("On clique");
$("<li>Coucou</li>").appendTo("<ul>");
}
Unfortunately, It doesn't work and I don't understand why.
Do you have any idea ?
The problem is because your selector is incorrect. appendTo('<ul>') is trying to create a new ul element in memory and append the li to that. You instead need to use appendTo('ul'), without the angle brackets.
I'd also suggest you use unobtrusive event handlers instead of the outdated onclick attributes. Here's the full example:
<!DOCTYPE html>
<html lang="fr">
<head>
<meta charset="utf-8">
<link rel="stylesheet" href="css/style.css">
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script type="text/javascript" src="js/index.js"></script>
</head>
<body>
<div class="filtres">
<input id="filtre1" type="button" value="filtre 1" />
</div>
<div id="liste">
<ul>
<li>Bonjour</li>
</ul>
</div>
</body>
</html>
jQuery(function($) {
$('#filtre1').on('click', function() {
console.log("On clique");
$("<li>Coucou</li>").appendTo("ul");
});
})
Try this:
function test() {
$('ul').append('<li>Hello!</li>');
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="liste">
<ul>
<li>Bonjour</li>
</ul>
</div>
<button onclick="test()">append</button>
append() will add an element at the end
function test() {
$('#liste > ul').append('<li>Coucou</li>');
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="filtres">
<input id="filtre1" type="button" value="filtre 1" onclick="test()">
</div>
<div id="liste">
<ul>
<li>Bonjour</li>
</ul>
</div>
<!DOCTYPE html>
<html lang="fr">
<head>
<meta charset="utf-8">
<link rel="stylesheet" href="css/style.css">
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script type="text/javascript" src="js/index.js"></script>
</head>
<body>
<div class="filtres">
<input id="filtre1" type="button" value="filtre 1" />
</div>
<div id="liste">
<ul>
<li>Bonjour</li>
</ul>
</div>
</body>

You have typo it should be onclick not oneclick.
function Show() {
document.getElementById('Khenchela').style.display = 'block'
}
function Hide() {
document.getElementById('Khenchela').style.display = 'none'
}

I have an Spring MCV 4 + HTML5 + Thymeleaf based application I can't seem to use javascript on pages.
The webapp structure is:
webapp
assets
css
img
js
i18n
messages.properties
WEB-INF
html
fragments
common.html
default.html
footer.html
header.html
login.html // exclusively for ../login.html
sidebar.html
home
welcomeSignedIn.html
client
home.html
create.html
In my login page, since it is a single page, with only a picture in the background, I have a piece of JS that works flawlessly:
<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head th:include="fragments/login :: loginFragment">
<meta charset="UTF-8" />
<title><th:text="#{app.name}"></label></th:text>
</head>
<body>
<div class="login-container animated fadeInDown">
<div class="loginbox bg-white">
<form th:action="#{/login}" method="post">
<div class="loginbox-title">SIGN IN</div>
<div class="loginbox-textbox">
<input type="text" id="ssoId" name="ssoId" class="form-control" placeholder="Username" />
</div>
<div class="loginbox-textbox">
<input type="password" id="password" name="password" class="form-control" placeholder="Password" />
</div>
<div class="loginbox-forgot">
Forgot Password?
</div>
<div class="loginbox-submit">
<input type="submit" class="btn btn-primary btn-block" value="Login"/>
</div>
</form>
</div>
</div>
<script type="text/javascript">
$(function () {
$('#ssoId').focus();
});
</script>
</body>
</html>
Login page has its own fragment, because it's a single, no menus, no sidebar page. All other are.
For may default templating, I have a file called fragments/default.html reponsible for pages organization.
<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org" xmlns:layout="http://www.ultraq.net.nz/thymeleaf/layout">
<head th:include="fragments/common :: commonFragment">
<meta charset="UTF-8" />
<title th:text="#{app.name}"> </title>
</head>
<body>
<div th:id="defaultFragment" th:fragment="defaultFragment">
<div th:replace="fragments/header :: headerFragment"></div>
<div class="main-container container-fluid">
<div class="page-container">
<div th:replace="fragments/sidebar :: sidebarFragment"></div>
<div class="page-content">
<div class="page-body">
<div layout:fragment="content"></div>
</div>
</div>
</div>
</div>
<div th:replace="fragments/footer :: footerFragment"></div>
</div>
</body>
</html>
So that, for every page, I get included the following links and scripts from fragments/common.html:
<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head th:id="commonFragment" th:fragment="commonFragment">
<link rel="icon" th:href="#{/assets/img/favicon.png}" type="image/x-icon" />
<link rel="stylesheet" th:href="#{/assets/css/bootstrap.min.css}" />
<link rel="stylesheet" th:href="#{/assets/css/font-awesome.min.css}"/>
<link rel="stylesheet" th:href="#{/assets/css/beyond.min.css}"/>
<link rel="stylesheet" th:href="#{/assets/css/demo.min.css}" />
<link rel="stylesheet" th:href="#{/assets/css/animate.min.css}" />
<link rel="stylesheet" th:href="#{/assets/css/skins/darkred.min.css}" />
<link rel="stylesheet" th:href="#{http://fonts.googleapis.com/css?family=Open+Sans:300italic,400italic,600italic,700italic,400,600,700,300}" />
<!--Skin Script: Place this script in head to load scripts for skins and rtl support-->
<script type="text/javascript" src="/assets/js/skins.min.js" th:src="#{/assets/js/skins.min.js}"></script>
<script type="text/javascript" src="/assets/js/jquery-2.0.3.min.js" th:src="#{/assets/js/jquery-2.0.3.min.js}"></script>
<script type="text/javascript" src="/assets/js/bootstrap.min.js" th:src="#{/assets/js/bootstrap.min.js}"></script>
<script type="text/javascript" src="/assets/js/slimscroll/jquery.slimscroll.min.js" th:src="#{/assets/js/slimscroll/jquery.slimscroll.min.js}"></script>
<script type="text/javascript" src="/assets/js/beyond.js" th:src="#{/assets/js/beyond.js}"></script>
<script type="text/javascript" src="/assets/js/beyond.min.js" th:src="#{/assets/js/beyond.min.js}"></script>
<script type="text/javascript" src="http://code.jquery.com/jquery-latest.js"></script>
</head>
<body>
<div class="container" />
</body>
</html>
My fragments/header.html is defined as:
<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head th:include="fragments/common :: commonFragment">
</head>
<body>
<div th:id="headerFragment" th:fragment="headerFragment">
// content
</div>
</body>
</html>
fragments/sidebar.html is very similar to `fragments/header.html, just different classes and content.
So, on every page I have on my application, I do something like this:
<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org" xmlns:layout="http://www.ultraq.net.nz/thymeleaf/layout" layout:decorator="fragments/default" xmlns:s="http://www.springframework.org/tags">
<head >
<title th:text="#{view.index.title}">Welcome!</title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
</head>
<body>
<div layout:fragment="content">
// content
</div>
</body
</html>
I'm sure it's something quite stupid, but I'm failing to see why can't I get javascript working on my pages, even for something quite as simple as:
<script type="javascript" >
$(function () {
alert('hello');
});
</script>
And, what's bothering (a lot!) is that if I on the browser something like:
localhost:8080/appName/assets/js/bootstrap.min.js
It will show the contents of the file.
What am I missing here?
Thanks for the input, guys! I got it working. What I did is placing the JavaScript section inside the <div layout:fragment="content">*HERE*</script> area, like on the example bellow.
<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org" xmlns:layout="http://www.ultraq.net.nz/thymeleaf/layout" layout:decorator="fragments/default" xmlns:s="http://www.springframework.org/tags">
<head >
<title th:text="#{view.index.title}">Welcome!</title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
</head>
<body>
<div layout:fragment="content">
<script type="text/javascript" >
*JavaScript area*
</script>
// content
</div>
</body
</html>
Hope this will save someone's precious time!
I think you have problems because there are 2 jquery files included to your fragments/common.html (check it via Firebug or something like that):
<head th:id="commonFragment" th:fragment="commonFragment">
...
<script type="text/javascript" src="/assets/js/jquery-2.0.3.min.js" th:src="#{/assets/js/jquery-2.0.3.min.js}"></script>
...
<script type="text/javascript" src="http://code.jquery.com/jquery-latest.js"></script>
</head>
Try to remove one of the definitions.
I want to fade in the page upon load. I looked at other forms on here and somehow it just isnt working for me...
Javascript file:
window.onload = init;
function init() {
$('#container').fadeIn('slow');
}
One of the pages:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Apparel</title>
<link rel="stylesheet" type="text/css" href="style.css">
<script src="effects.js"></script>
</head>
<body>
<div id="cart">
<img src="shopcart.jpg" height="30px">
</div>
<div id="container">
<div id="nav">
<p id="sb">Apparel</p>
<p id="about">HOME</p>
<p id="srv">OUTERWEAR</p>
<p id="srv">CLOTHING</p>
<p id="pjt">SHOES</p>
<p id="pjt">ACCESSORIES</p>
<p id="about">ABOUT</p>
<p id="cont">CONTACT</p>
</div>
<div id="imgcontainer">
<img src="homeimg.jpg">
</div>
</div>
</body>
</html>
Put
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
above
<script src="effects.js"></script>
This exposes the $ variable (aka the jQuery library) that you're using when you do $('#container')
You'd better replace the window.onload to $(function(){});
Here is the code:
<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript">
//window.onload = init;
$(function(){
init()
});
</script>
Enjoy it : )
I've a problem with prettyphoto and a simple jquery script in a PrettyPhoto inline box.
Why I can't hide the div in this prettyphoto box? I don't understand why this is not working...
<!DOCTYPE html>
<html>
<head>
<title>Pretty photo test</title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js" type="text/javascript"></script>
<link rel="stylesheet" href="css/prettyPhoto.css" type="text/css" charset="utf-8" />
<script src="js/jquery.prettyPhoto.js" type="text/javascript" charset="utf-8"></script>
</head>
<body>
<li>Inline content 1</li>
<div id="inline_demo" style="display:none;">
<div id="testje" style="display:block">this is a test</div>
<a onclick="$('#testje').hide(); return false">Close test div</a>
</div>
<script type="text/javascript" charset="utf-8">
$(document).ready(function(){
$("a[rel^='prettyPhoto']").prettyPhoto();
});
</script>
</body>
</html>
No need to add [inline] :
<li>Inline content 1</li>
<div id="inline_demo" style="display:none;">
<div id="testje">this is a test</div>
<a onclick="$('#testje').hide(); return false;">Close test div</a>
</div>
I am trying to build a Web application using jQuery Mobile.
When testing on my desktop everything works as expected.
On Android (both 3.2 and 4.0.3) seems like JavaScript is disabled after navigating to second page.
My first page looks like:
<!DOCTYPE html>
<html>
<head>
<title>Hello World</title>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet"
href="script/jquery.mobile-1.1.0/jquery.mobile-1.1.0.min.css" />
<script type="text/javascript" src="script/jquery-1.7.2.min.js"></script>
<script type="text/javascript" src="script/jquery.mobile-1.1.0/jquery.mobile-1.1.0.min.js"></script>
</head>
<body>
<div data-role="page">
<div data-role="header">
<h3>Jetty experiments:</h3>
</div>
<div data-role="content">
<ul data-role="listview">
<li>Hello World</li>
<li>Sample Form</li>
<li>Test JSP</li>
</ul>
</div>
<div data-role="footer">
<button id="jquery-test">JQuery Test</button>
</div>
</div>
</body>
<script type="text/javascript">
$(document).ready(function() {
$("#jquery-test").click(function(event) {
alert("OK");
});
});
</script>
</html>
My second page (that is sample-form.html):
<!DOCTYPE html>
<html>
<head>
<title>Collects text into a database</title>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">

<div data-role="content">

</form>
<ul id="names" data-role="listview">
<li data-template>{{name}}</li> <!-- the template here does not work on Android -->
<li data-template-fallback>Sorry, JavaScript required!</li>
</ul>
</div>
<div data-role="footer">
<button id="jquery-test">JQuery Test</button>
</div>
</div>
</body>
<script>
var names;
$(document).ready(function() {
$("#jquery-test").click(function(event) {
alert("OK"); // the alert here does not work on Android :(
});
names = Tempo.prepare("names")
});
// this binding does not work on Android
$("#searchForm").submit(function(event) {
event.preventDefault();
$.getJSON("SampleForm", function(data) {
names.render(data);
});
});
</script>
</html>
Any idea what am I doing wrong?
BR,

In jQuery Mobile the document ready event is called once. Linked pages are loaded in same DOM and page init is triggered.

Here is another question:
jQuery Mobile delegate vs live vs bind
