I am having the following code, i tried with jQuery live and on plugin, while trying with live, i am able to add the event handler which is already present for the element with the class "button" to the newly added element(added dynamically after page load) with the class "button" but on trying with the jQuery on plugin, i am unable to add the already existing event handler to the newly added element.
Example with Live
<html xmlns="http://www.w3.org/1999/xhtml" lang="en">
<head>
<!--START: Adding of javaScript library -->
<script type="text/javascript" src="script/jquery.min.js"></script>
<!--END: Adding of javaScript library-->
<!--START: Adding of javaScript library need internet Connection-->
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<!--END: Adding of javaScript library need internet Connection-->
</head>
<script>
jQuery(document).ready(function(){
jQuery(".button").live("click", test);
});
var i=0;
function test(event){
var elem=jQuery(this).parent().html();
jQuery("body").append("<div class=DivClass" + i++ + ">"+elem+"</div>" );
}
</script>
<body>
<div id="Container"><input value="click me" class="button" type="button"/></div>
</body>
</html>
Example With On
<html xmlns="http://www.w3.org/1999/xhtml" lang="en">
<head>
<!--START: Adding of javaScript library -->
<script type="text/javascript" src="script/jquery.min.js"></script>

<!--END: Adding of javaScript library need internet Connection-->
</head>
<script>
jQuery(document).ready(function(){
jQuery(".button").on("click", test);
});
var i=0;
function test(event){
var elem=jQuery(this).parent().html();
jQuery("body").append("<div class=DivClass" + i++ + ">"+elem+"</div>" );
}
</script>
<body>
<div id="Container"><input value="click me" class="button" type="button"/></div>
</body>
</html>
and moreover i am able to put the event handler binding code using live outside of jquery ready which is working fine but if i put event handler binding using on outside of jquery ready, the event handler is not working.Thanks in advance for any help.
If you want to have your selector to be dynamically tested, you must pass it as argument, as in your code you're calling a function on a constant empty collection :
jQuery(document).ready(function(){
var i=0;
function test(event){
var elem=jQuery(this).parent().html();
jQuery("body").append("<div class=DivClass" + i++ + ">"+elem+"</div>" );
}
$(document).on("click", ".button", test);
});
(you'll see I defined test here before I pass it to the function, your code hurts my eyes)
jQuery('body').on('click', '.button', test);

I am trying to learn JQuery running sample codes dealing with SetInterval or Settimeout I find on the Internet, but they won't run or work. For instance, I have the following simple code, but it won't run or even give me error message.
<!DOCTYPE html>
<html>
<head>
<title>testing</title>
<script type="text/javascript">
$(document).ready(function(){
setInterval(function() {
var number = 1 + Math.floor(Math.random() * 333);
$('#here').load(number);
},
1000);
});
</script>
</head>
<body>
<div id="here">dynamic content ?</div>
</body>
</html>
You first missed to add jquery library and second you should use .text() function rather than .load() function.
.load() function should use for ajax method.
One of the essential rules that should keep in mind that always put javascript code at the end of the page and before the end of the body tag
$(document).ready(function() {
setInterval(function() {
var number = 1 + Math.floor(Math.random() * 333);
$('#here').text(number);
}, 1000);
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<!DOCTYPE html>
<html>
<head>
<title>testing</title>
</head>
<body>
<div id="here">dynamic content ?</div>
</body>
</html>
I have written a simple example to demonstrate the use of bootstrap notify but its not working.
Below is my code:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
<script src="bootstrap-notify.js"></script>
<script src="bootstrap-notify.min.js"></script>
<script>$.notify("Hello World");</script>
</head>
<body>
</body>
Replace your script as below just add ready function it work fine. and also add bootstrap css for look good.
<script>
$(document).ready(function(){
$.notify("Hello World");
});
</script>
I have a code like this:
parent.html:
<head>
<script
src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js">
</script>
<script src="jquery-ui-1.11.4/jquery-ui.min.js"></script>
<script>
$(function() {
$("#test").draggable().click(function() {
$("#objeto").attr('data', "child2.html").draggable();
});
});
</script>
</head>
<body>
<h2 id="test">text(draggable/click)</h2>
<object id="objeto" data="child1.html"></object>
</body>
and
child2.html:
<head>
<script
src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js">
</script>
<script src="jquery-ui-1.11.4/jquery-ui.min.js"></script>
<script>
$(function() {
$("#text").draggable();
});
</script>
</head>
<body id="text">child2 (draggable)
</body>
This works correctly, parent loads with child1 content and if you click on "text" it switches to child2, but what i want to know is:
am I downloading jquery.min.js and jquery-ui.min.js 2 times? or are is the second time pulled from cache? (since i'm asking for the same file again)
is there a way I could use jquery without including it on the child's header? (since it is already on the parent)
.load() only works on files coming from a server, so it will work later as I'm going to put this on a server
Edit: This code works on firefox but not on chrome
I've been trying to use ajax to load a webpage after selecting an option but the script doesn't even seem to load
here's the script + html:
<!DOCTYPE HTML>
<html>
<head>
<meta charset="utf-8" />
<link rel="stylesheet" href="DaVinciRace.css" />
<title> Da Vinci Race 2014-2015 </title>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js" ></script>
</head>
<body style="background:#f2f2f2;">
<div id="logo">
<img src="Resources\DVRLogo.png"/>
<!-- <p class="text">Da Vinci Race</p> -->
</div>
<div id="options" style="background:#0c0c0c; float:right;">
<div class="menu">
<div class="chronometre" ></div>
</div>
</div>
<div id="DVRChrono">
</div>
<script>
$(document).ready(function(){
$("#options").on("click", ".chronometre", function() {
$( "#DVRChrono" ).load( "Chronometre.html" );
})
});
</script>
</body>
</html>
the document "Chronometre.html" is in the same folder as this html page
I feel like I'm missing something obvious but can't for the life of me figure out what it is
Try this:
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js" ></script>
<script>
(function($){
$("#options").on("click", ".chronometre", function() {
$( "#DVRChrono" ).load( "Chronometre.html" );
})
})(jQuery)
</script>
This isn't adding a click handler:
$("#options").on("click", ".chronometre", function() {
// code
});
Because it executes before the #options element exists on the page. The code is executing without error, the jQuery selector simply isn't finding anything. So there are no elements to which a handler can be attached.
You can fix this either by moving the code to the end of the page or by wrapping it in the document.ready handler:
$(function() {
$("#options").on("click", ".chronometre", function() {
$( "#DVRChrono" ).load( "Chronometre.html" );
});
});
Additionally, your script tags are broken. Each tag should have either a src or content, but not both. Separate them:
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
<script type="text/javascript">
// your code
</script>
I'm new to web development and I'm trying to understand how the DOM works.
I have a basic page with 2 buttons and some text. One of the buttons does a call to Jquery's Get function. My server returns some html with some script as well. Which is then added to my DIV on my main page which has an ID of 'content'
See below for the code.
Main Page
<!DOCTYPE html>
<link rel="stylesheet" href="css/toastr.css">
<html>
<body>
<h1>My Main Page </h1>
<button class="alertmsg">click me</button>
<button class="addDom" >Call Add HTML</button>
<div id="content">
</div>
</body>
</html>
<script src="js/jquery.js"></script>
<script src="js/toastr.js"></script>
<script>
$(document).ready(function(){
$(".alertmsg").click(function() {
alert("Hello World!");
});
$(".addDom").click(function(){
$.get( '/adddom',
function (data) {
// put html into the section
$("div#content").html(data);
})
});
});
</script>
Code Returned
<div>
<h1>Added Via $.html</h1>
<button class="showmsg">click me for jquery</button>
</div>
<script>
$(document).ready(function(){
$(".showmsg").click(function(){
toastr.warning( "Test Warning", 'Warning');
});
});
</script>
The Updated DOM - notice that my new javascript aren't seen.
<!DOCTYPE html>
<link rel="stylesheet" href="css/toastr.css">
<html>
<body>
<h1>My Main Page </h1>
<button class="alertmsg">click me</button>
<button class="addDom" >Call Add HTML</button>
<div id="content">
<div>
<h1>Added Via $.html</h1>
<button class="showmsg">click me for jquery</button>
</div>
</div>
</body>
</html>
<script src="js/jquery.js"></script>
<script src="js/toastr.js"></script>
<script>
$(document).ready(function(){
$(".alertmsg").click(function() {
alert("Hello World!");
});
$(".addDom").click(function(){
$.get( '/adddom',
function (data) {
// put html into the section
$("div#content").html(data);
})
});
});
</script>
What I'm trying to understand is;
1) Where does my new script code exist?
<script>
$(document).ready(function(){
$(".showmsg").click(function(){
toastr.warning( "Test Warning", 'Warning');
});
});
</script>
is it in memory only and not in the DOM?
2) I can get the warning to show correctly i.e $(".showmsg").click
fires and shows what is expected. So my my script can reference the existing libraries in the DOM which are needed. How does this work?
3) What is the best way to trouble shoot this code if I cannot see it in my browser?
Many thanks!
If you really want to append the script to the dom you need to use appendChild() not .html(). link about appendChild
An example of doing this would be
var script = document.createElement( 'script' );
script.type = 'text/javascript';
script.text = 'alert("test");';
$('div')[0].appendChild(script);
Here is a fiddle showing this.
