You are using slim version of jQuery. It Doesn't support ajax Calling.
Use
<script src="https://code.jquery.com/jquery-3.2.1.min.js"></script>
instead of it.
Slim build
Sometimes you don’t need ajax, or you prefer to use one of the many
standalone libraries that focus on ajax requests. And often it is
simpler to use a combination of CSS and class manipulation for all
your web animations. Along with the regular version of jQuery that
includes the ajax and effects modules, we’ve released a “slim” version
that excludes these modules. All in all, it excludes ajax, effects,
and currently deprecated code. The size of jQuery is very rarely a
load performance concern these days, but the slim build is about 6k
gzipped bytes smaller than the regular version – 23.6k vs 30k. These
files are also available in the npm package and on the CDN:

jQuery / javascript How to load Script when a css class presents in the page

I have a page shows a list of rows and with a pagination, when you click on next page the next page loads in same page contains another list of rows. so basically next page loads a bunch of other rows without my exact page been reloaded
So the problem im haven is i use this script below while it works fine but when the next page loads in same window this script does not work for them.
I hope i make sense here :) what is a good solution for this?
$('.ltwitch').each(function () {
var tnick = $(this).data('tnick');
var span = $(this).next();
$.getJSON("https://api.twitch.tv/kraken/streams/" + tnick + ".json?callback=?", function (data) {
if (data.stream === null) {
span.html(
'<strong class="ipsOnlineStatus ipsOnlineStatus_offline"><i class="fa fa-circle"></i></strong><h4 class="ipsDataItem_title ipsType_break"> ' + tnick + ' </h4><div class="ipsDataItem_meta">Offline</div>');
} else {
var views = data.stream.viewers;
var game = data.stream.game;
span.html(
'<strong class="ipsOnlineStatus ipsOnlineStatus_online"><i class="fa fa-circle"></i></strong><h4 class="ipsDataItem_title ipsType_break"> ' + tnick + ' </h4><div class="ipsDataItem_meta"> ' + views + ' viewers </div><div class="ipsDataItem_meta">Playing: '+ game +' </div>');
}
$(function() {
var online = $('.ipsOnlineStatus_online').closest('.cCmsRecord_row');
var first = $('.cCmsRecord_row')[0];
online.each(function() {
$(first).before(this);
});
});
short of HTML
<ol class="List">
<li class="row">
<div class="main">
<a href="#" class="ease">
<div class="ltwitch" data-tnick="esl_lol"></div>
</a>
</div>
</li>
<li class="row">
<div class="main">
<a href="#" class="ease">
<div class="ltwitch" data-tnick="esl_lol"></div>
</a>
</div>
</li>
....
....
....
</ol>
<div data-role="tablePagination">
<ul class="ipsPagination">
<li class="ipsPagination_prev ipsPagination_inactive">Prev</li>
<li class="ipsPagination_next">Next</li>
</ul>
</div>
It sounds like you want to wrap your work in a named function so you can call it on subsequent paging. Your code right now is most likely in a document ready which is only called on initial page load. Turning all of that work into a function now allows it to be called many times.
function myFunction () {
...
};
myFunction();
Then where your pagination code is set up ( I figure an anchor click binding ) just call myFunction() again.
$('.ipsPagination_next').click(function(){
...
myFunction();
});
I would note that if these two areas are in different document ready functions or different files, ideas like scope and encapsulation might become problematic. We'd have to see more code to confirm if it would be an issue. If you are having problems you could put the function myFunction() onto the root which would be outside of any document ready, load, or whatever you might be using. Then it would be on the root or window level.
window.myFunction = function () {
...each(... your current work
};
This could be used if you aren't sure about encapsulation or how scope works.
Your $('.ltwitch') selector only captures the classes present in the first page. When a subsequent page is loaded, $('.ltwitch') is not executed again on the new classes.
I suggest that you somehow differentiate between classes corresponding to already loaded pages, and classes corresponding to new pages. You could do this by adding a class, e.g. .already-loaded to the classes as you load them.
$.getJSON("https://api.twitch.tv/kraken/streams/" + tnick + ".json?callback=?", function (data) {
$(this).addClass('already-loaded'); // Mark as loaded.
...
This way, replace your first line with this:
$('.ltwitch').not('.already-loaded').each(function () {
...
Not tested, but could work.

jQuery loads external HTML file but does not stay still after page refresh

I am trying to do something different without knowing if it is a good idea or not
I have a navigation menu as the following:
...
<li>Home</li>
<li>FAQ</li>
<li>Contact</li>
...
I do not want to use a server-side scripting because it takes more time to make db connection and define some configuration, and not want to multiply the pages for each one. So I made a master page index.php
in body section
there are two elements:
an h3 element to display the page title and a div to display the content which is called from another html source.
...
<div class="container">
<h3 id="pageTitle"></h3>
<div id="pageContent"></div>
</div>
...
I am using jQuery's click event to load the page into the div
$(function() {
$("a[href^='#m']").click(
function() {
$("#pageTitle").text($(this).text());
$("#pageContent").load($(this).attr("href").substring(1) + ".html"); //removing # char.
});
});
It works fine. But when I press F5 it returns the initial state as normal. How can I load the current page by referencing the address bar (I can see eg. sitename/#mfaq) when page is refreshed.
I think, first I need to detect if page is refreshing and load the corresponding html file in according to the #m**** on the addressbar.
$(function() {
$("a[href^='#m']").click( function(evt) {
// ------ This should work
// renamed parameter elem to evt like corrected in comment
evt.preventDefault();
$("#pageTitle").text($(this).text());
$("#pageContent").load($(this).attr("href").substring(1) + ".html");
});
});
Add to your DOM ready function:
if (window.location.hash != "") {
$("#pageTitle").text($("a[href='"+window.location.hash+"']").text());
$("#pageContent").load(window.location.hash.slice(1) + ".html");
}
I have made this. It works well. But I am not sure about performance issues:
$(function() {
var address = $(location).attr('href');
var hash = address.lastIndexOf("#");
var page = address.substring(hash+1);
if (hash < 1)
{
$("#pageContent").load("mhome.html");
$("#pageTitle").html("Default Page Title");
}
else
{
$("#pageContent").load(page + ".html");
$("#pageTitle").html($("a[href='" + address.substring(hash) + "']").text());
}
$("a[href^='#m']").click(
function() {
$("#pageTitle").text($(this).text());
$("#pageContent").load($(this).attr("href").substring(1) + ".html");
});
});

Clever work-around for my current script?

I'm currently utilizing JavaScript to allow users to watch multiple videos on a page. There is one big player at the top of the page, and below it are smaller thumbnails of more videos.
In theory, it works fine. However, there is one major problem: ALL videos load at the same time as the page loads.
See this page for reference. I have assigned JavaScript alerts to each individual videos to exemplify the problem (video1, video2, etc.).
Is there a easy fix, without having to rewrite the entire page, to have the videos load when they are clicked on, not when the page loads? Here's what the code looks like so far:
Javascript that calls the video:
function playVideo(cap, file, streamer, alertmsg) {
var so = new SWFObject('player/player-licensed_5_2.swf', 'ply1', '586', '330', '9');
so.addParam('displaywidth', '586');
so.addParam('displayheight', '330');
so.addParam('allowfullscreen', 'true');
so.addParam('allowscriptaccess', 'always');
so.addVariable('skin', 'player/skins/glow.zip');
so.addVariable('controlbar', 'over');
so.addVariable('plugins', 'captions-1');
so.addVariable('captions.file', cap);
so.addVariable('dock', 'true');
so.addVariable('image', 'landing_img/video.jpg');
so.addVariable('file', file);
so.addVariable('streamer', streamer);
so.addVariable('autostart', 'false');
so.write('player1');
window.alert(alertmsg);
}
The thumbnail for the video:
<div class="mini_player1"> <a href="#" class="vidpic" title="">
<!-- thumbnail-->
<img src="images/1_panda.jpg" alt="Video 1" class="vidpic" />
<span class="play-button"><img src="images/yt.png" alt="Play"></span>
</a>
</div>
<div class="content_mini_player1 cmp">
<script>
playVideo('<caption file>', '<videofile>', '<streamer>', 'video1');
</script>
</div>
The script that 'replaces' the content in bigplayer with the new selected video:
jQuery(function ($) {
$(".mini_player1, .mini_player2, .mini_player3, .mini_player4, .mini_player5, .mini_player6, .mini_player7, .mini_player8, .mini_player9, .mini_player10, .mini_player11, .mini_player12, .mini_player13, .mini_player14, .mini_player15, .mini_player16, .mini_player17, .mini_player18, .mini_player19, .mini_player20").click(function () {
var player_content_id = "content_" + $(this).attr("class");
var player_content = $("." + player_content_id).html();
$(".big_player").html('');
$(".big_player").html(player_content);
});
});
Any suggestions? Maybe consolidate playVideo and the jQuery function? Any help would be greatly appreciated.
Firstly, in the thumbnail code, there is a random closing </a> tag. Unless there is code you didn't post, I'd suggest removing it.
Secondly, your jQuery can be simplified much further. Currently, you are using the following selector:
$(".mini_player1, .mini_player2, .mini_player3, .mini_player4, .mini_player5, .mini_player6, .mini_player7, .mini_player8, .mini_player9, .mini_player10, .mini_player11, .mini_player12, .mini_player13, .mini_player14, .mini_player15, .mini_player16, .mini_player17, .mini_player18, .mini_player19, .mini_player20")
Wow! That is...wow.
Assign the players a single class they can all relate to across the board, select by that class and then run the each() method i.e.:
$(".mini-player").each(function() {
var player_content_id = "content_" + $(this).attr("class");
var player_content = $("." + player_content_id).html();
$(".big_player").html('');
$(".big_player").html(player_content);
});
Lastly, when you call a function in a script tag like you are doing:
<script>
playVideo('<caption file>', '<videofile>', '<streamer>', 'video1');
</script>
This WILL run the playVideo() function. Consolidating playVideo() and the jQuery code would be your best bet i.e. (using the same construct above):
$(".mini-player").each(function() {
var player_content_id = "content_" + $(this).attr("class");
var player_content = $("." + player_content_id).html();
$(".big_player").html('');
$(".big_player").html(player_content);
//Add event handler
$(this).on('click',function() {
playVideo('<caption file>', '<videofile>', '<streamer>', 'video1');
});
});
Your inline JavaScript function playVideo is going to be called when the page loads. You will want to remove it from there and do something like this:
<div onclick="playVideo()" class = "mini_player1">

Swipe JS not working with populated content

I'm using Swipe JS 2.
If I make the HTML structure myself, it works perfectly, but if I populate the HTML with content coming from the jQuery, it stops on the second slide.
My HTML structure:
<div id="map" class="swipe">
<div class="swipe-wrap">
<div class="city" id="current">
<div class="location">Current Location</div>
</div>
</div>
</div>
<nav>
<ul id="position">
<li class="on">Current location</li>
</ul>
</nav>
This is my structure on the jQuery.
$.getJSON("http://localhost/locations.php", function(localdata) {
$.each(localdata.locations, function(i, geolocal){
var vcountry = geolocal['country'];
var vregion = geolocal['region'];
var vcity = geolocal['city'];
country = vcountry.replace(' ','_');
region = vregion.replace(' ','_');
city = vcity.replace(' ','_');
// THE PROBLEM IS HERE. IF I USE AJAX OR GETJSON HERE INSIDE THE OTHER GETJSON, THE SWIPE IS BROKEN.
$.ajax({
type: "GET",
url: "http://localhost/remotexml.php?url=http://www.yr.no/place/"+ country +"/"+ region +"/"+ city +"/forecast.xml",
success: function(xml) {
var localName = $(xml).find('location name').text();
$('#map div.swipe-wrap .city:last-child').after('\n<div class="city">\n<div class="location">'+localName+'</div>\n</div>\n</div>');
$('#position').append('\n<li>'+localName+'</li>');
}
});
});
})
.success(function() { })
.error(function() { })
.complete(function() {
var slider =
Swipe(document.getElementById('map'), {
auto: 5000,
continuous: true,
callback: function(pos) {
var i = bullets.length;
while (i--) {
bullets[i].className = ' ';
}
bullets[pos].className = 'on';
}
});
var bullets = document.getElementById('position').getElementsByTagName('li');
});
What happens is: when I see the HTML created by the jQuery, is perfect. jQuery is creating the divs inside the slider and the lis inside the list. Perfect. When I run the website, load and starts perfectly, but then, when changes slide, stops on the second slide, and the second slide is blank. Nothing there. Even thought there is content on the HTML.
The most weird part? If I start the Developer Tools (Command + Alt + I on Chrome), right after the website loads, it WORKS PERFECTLY. What kind of bizar behavior is this? :D
Anybody can help me to make this Swipe JS to run?
If you're populating the slider with content via an AJAX request, then you will most likely have to wait until that AJAX request is finished before you build the slider - i.e. in the success callback of your AJAX function.
