This script is triggered only once when the page loads.
The page has loaded, click the link, the data came from.
Click the link again, nothing.
Overload the page, the link works, etc.
What is wrong in the script, why it triggered only once?
<script>
$(function() {
$('a').click(function() {
$.get('ajax', function(data) {
$('#mydiv').html(data);
});
});
});
</script>
<div id="mydiv">
Update the div!
</div>
Compared the data in the "mydiv" before and after clicking the link:
before clicking the link
<div id="mydiv">
<a href="#">
Update the div!
</a>
</div>
after link was cliked
<div id="mydiv">
<a href="#">
Update the div!
<!--Here is the data that came from.-->
</a>
</div>
Because you're overwriting the a tag that you attached the click event to, you'd need to rerun the code that attaches the click event again. Or you could use event delegation like blex suggests:
$(document).on("click", "a", function(){
}
Because of dynamically created a you should use:
$(document).on("click", "a", function() {

I load a page inside a div. This div supposed to trigger a function on a mouse click. I would like that this onClick event also works when you click on the loaded page.
If you load a page inside the div, the functions of the loaded page only works for that page.
How can I make it happen that also the onClick function get triggered for the loaded page?
This is a simple example of the code:
function load() {
var url_view = '<object type="text/html" data="http://www.example.com/"></object>';
document.getElementById("image").innerHTML=url_view;
}
window.onload = load;
function showbox() {
alert("test");
}
<div id ="frame" onclick="showbox()">
<div id="image">
</div>
<div class="infotext">
<span>here comes some text.</span>
</div>
</div>
To be clear
What I want to achieve is that when you load the page, you'll load data from example.com in a div with the id "image". This event happens with the function 'load()', on window.load.
When that is ready, I would like that you trigger the 'showbox()' function on a mouseclick when you click inside the div with the id "image" (the div where example.com is loaded into).
You can try something like this:
<div id ="frame">
<div id="image">
</div>
<div class="infotext">
<span>here comes some text.</span>
</div>
</div>
JS:
function showbox() {
alert("show box");
}
$(document).ready(function() {
$.get('https://jsfiddle.net/about', function(data) {
$('#image').html(data);
showbox();
});
$('#image').click(function() {
showbox();
});
});

I have added links into popover data-content. How can I perform a click() action on the links I have placed inside the data-content of popover-->(Bootstrap)
I have provided html anchor tags inside the data-content="" attribute of popover button.
Below is a link which upon clicking will show the popover content. The data content inside the popover has one upload and one download link.
Now I want to perform click action on the upload and download link. How can I do that?
<html>
<body>
<a href="#"
data-toggle="popover-upload"
data-trigger="focus"
data-placement="bottom"
title=""
data-content="<div class='link-Updown'>
<a href='' class='upload' title='Upload the Zip file here'
style=" margin: 7px;margin-bottom: 7px;display:block;">Upload</a>
<a href='' title='Download'
style=" margin: 7px;margin-bottom: 7px;display:block;">Download</a></div>"
style="font-family: calibri; font-size: 15px;color: darkslategrey;font-weight: bolder" ><i>Upload/Download</i>
</a>
<script>
$(document).ready(function(){
$('[data-toggle="popover-upload"]').popover({html:true})
.on("click",function(){});
})
</script>
</body>
</html>
The problem is that the popover content is inserted dynamically. This means that on init the html is not present in the DOM so no click event can be attached yet.
To solve this you can delegate the event by making a parent element listen to the event:
<a href="#" data-toggle="popover-upload" data-content="
<div class='link-Updown'>
<a href='#'>Upload</a>
<a href='#'>Download</a>
</div>">
Upload/Download
</a>
<script>
$(document).ready(function() {
$('[data-toggle="popover-upload"]').popover({ html: true });
// delegate click event from the document
$(document).on("click", ".link-Updown a", function(event) {
event.preventDefault();
console.log("download or upload clicked")
})
});
</script>
Right now you're listening to clicks on the container element instead of the anchor tags within the popover content.
You could do something like this:
$('[data-toggle="popover-upload"]').popover({
html:true
}).parent().on('click', '.link-Updown a', function(e) {
e.preventDefault();
// do your thing
});
You could distinguish between clicks on Upload or Download by giving them a data attribute data-action which you can read with $(this).data('action').
See this working fiddle.
Okay below I have posted the script I'm using and the #targetDiv, Basically my problem is when I move the link that is currently contained within the #targetDiv outside of the div, The link no longer loads the page inside of the div, Is there a way I can move the link outside of the #targetDiv and still have it load the page contents inside of the div.
Script
$(function(){
$('#targetDiv').on('click', 'a', function(e){
e.preventDefault();// prevent browser from opening url
$('#targetDiv').load(this.href);
});
});
Div
<div id="targetDiv" class="collapse">
Load
</div>
The problem I have is that I want the load link to be outside of the target div however when I move it outside of the div it loads the main page not the content within the targetDiv.
What I'm trying to achieve;
Load
<div id="targetDiv" class="collapse">
</div>
Add a class to any links you want to use to load content
<a class="content-link" href="/page.php">Load</a>
And modify event listener accordingly so it handles both types of links
$(document).on('click', '.content-link, #targetDiv a',function(e){
e.preventDefault();// prevent browser from opening url
$('#targetDiv').load(this.href);
});
Try this:
$(function(){
$('#divLoad').click(function(e){
e.preventDefault();// prevent browser from opening url
$('#targetDiv').load(this.href);
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<a id="divLoad" href="/page.php">Load</a>
<div id="targetDiv" class="collapse">
</div>
You can also do this (more difficult to be precise):
$(function(){
var divLoad = $('#targetDiv').prev('a');
//alert(divLoad.attr('href') );
divLoad.click(function(e){
e.preventDefault();// prevent browser from opening url
$('#targetDiv').load(this.href);
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<a id="divLoad" href="/page.php">Load</a>
<div id="targetDiv" class="collapse">
</div>
What I need
I need when user click on link data is shown.
link disappear after click.
I have tried code
<a href="javascript:void(0);" class="viewdetail more"
style="color:#8989D3!important;">view details
<div class="speakers dis-non">
</div>
</a>
jquery code
$('.viewdetail').click(function() {
$(this).find('.speakers').show();
$(this).find('.viewdetail').hide();
});
problem
when I click on view detail link data is shown on div.
link doesn't disappear.
if I put anchor before div then data is not shown on speaker class div.
any suggestion are most welcome.
jsfiddle: http://jsfiddle.net/fw3sgc21/
Since the div is inside the anchor, the div will also be hidden if you hide the anchor. You need to put the div next to the anchor to make it work. Use next() method to select the div.
HTML
view detail
<div class="speakers dis-non" style="display: none">
test data to be shown
</div>
JS
$('#viewdetail').on('click', function(){
// show div with speakers class next to the anchor
$(this).next('div.speakers').show();
// hide the anchor
$(this).hide();
});
JSFiddle: http://jsfiddle.net/fw3sgc21/2/
EDIT
If you want to wrap the speakers div inside another div as below
view detail
<div class="12u">
<div class="speakers dis-non">
test data to be shown
</div>
</div>
with the following CSS
.dis-non
{
display: none;
}
Here's the JS that should show the speakers div and hide the clicked anchor
$('#viewdetail').on('click', function(){
$(this).next().children('div.speakers').show();
$(this).hide();
});
JSFiddle: http://jsfiddle.net/fw3sgc21/6/
EDIT 2
If you want to put the anchor inside two divs as below
<div class="a">
<div class="b">
view detail
</div>
</div>
<div class="12u">
<div class="speakers dis-non">
test data to be shown
</div>
</div>
Use .parent() method twice to select <div class="a">, then use .next().children('div.speakers').show() to show the speakers div
$('#viewdetail').on('click', function(){
$(this).parent().parent().next().children('div.speakers').show();
$(this).hide();
});
JSFiddle: http://jsfiddle.net/fw3sgc21/8/
Try the following:
$('.viewdetail').click(function()
{
$('.speakers').show();
$(this).hide();
});
$(this) refers to the .viewdetail so you don't need the find it again
Pull the div outside the hyperlink
HTML:
view details
<div class="speakers dis-non"></div>
try this
html
<a href="javascript:void(0);" id="viewdetail" style="color:green">view detail
</a>
<div class="speakers dis-non">
test
</div>
js
$('#viewdetail').click(function() {
$('.speakers').show();
$(this).hide();
});
http://jsfiddle.net/fw3sgc21/1/
First of all this in your code refers to to the clicked link itself.
So this line $(this).find('.viewdetail').hide(); doesn't work, because there is no .viewdetail inside of link. It should be
$('.viewdetail').on('click',function(e) {
var self = $(this);
self.find('.speakers').show();
self.hide();
});
But, if you hide your link, the .speakers will be also hidden, because it's inside of your link. If you want it to be visible, you should place it outside of link
For example:
view details
<div class="speakers dis-non"></div>
And JS:
$('.viewdetail').on('click',function(e) {
var self = $(this);
e.preventDefault(); // prevent link from working the way it should
self.next('.speakers').show();
self.hide();
});
On my jQuery mobile app;
On menu.html and inside body I do something like this to go help.html;
....
$(document).off('pageinit', '#menupage').on('pageinit', '#menupage', function() {
$(document).off('click', '#help').on('click', '#help', function(){
$.mobile.changePage("help.html", {
reloadPage: true,
transition: "flip",
reverse: false
});
});
}
....
<li><a id="help" href="#" role="link" data-role="none">
<div class="img help"></div>
<div class="menuTitle langMenuItem3">Help</div>
<div class="arrow"></div>
</a></li>
Then on the help.html page I have a back button like this to go back to menu.html:
<header data-role="header">
<a href="#" data-rel="back" class="button" data-role="none">
<div class="arrow_reverse"></div><span class="langBack">Terug</span>
</a>
<div class="pageTitle">Over deze app</div>
</header>
My problem is this works under normal conditions, BUT if I make a refresh on menu.html, then go to help.html and then go back to menu again, menu.html does not load properly, I can see the page visually loaded ok but on firebug I see that some necessary javascripts inside tags does not hit anymore, It never hits any javascripts anywhere on menu.html anymore, just loads the previous html from cache thats all. Also the page title of menu.html does not change correctly and stays as "Help" after that point.
my full menu.html looks like this;
http://jsfiddle.net/M5CYZ/
Any ideas?
Do it this way.
Give back button an ID
<a href="#" id="backbtn" class="button">
<div class="arrow_reverse"></div><span class="langBack">Terug</span>
</a>
and then add the below code in help.html
$('#backbutton').off('click').on('click', function () {
$.mobile.changePage("menu.html", {
reloadPage: true,
transition: "flip",
reverse: true
});
});
This is a wild guess but according to your code this is a normal behaviour.
jQuery Moible event pageinit will trigger only once during the initial page load and unless page is refreshed (manually, with rel="external" or in your case reloadPage="true") it will never trigger again.
If you want javascript to execute again each time page is visited then use pagebeforeshow event instead. As seen in your example, removing pageinit and adding it back will not help you.
If you want to find more, read my other answer/article about page events: jQuery Mobile: document ready vs page events
And here's an example to prove my point: http://jsfiddle.net/Gajotres/Q3Usv/
$(document).on('pageinit', '#index', function(){
alert('Pageinit');
});
$(document).on('pagebeforeshow', '#index', function(){
alert('Pagebeforeshow');
});
