I have a external .js source that works fine when I use the script internally but I want to make it reloadable using a button, so that when I click the button it loads the script into a div, without having to refresh the page, although I have less... no experience with jQuery and when I use the script...
<button id="SpotifyPlaying">(Re)Load</button>
<script>
$(document).ready(function () {
$("#SpotifyPlaying").on("click", function () {
$("#playing").load("/spotifyhtml.js")
});
});
</script>
It does not appear in the div. the script uses
var element = document.getElementById("playing");
element.innerHTML = r;
and the code is proper functioning, as well as the div it functions in is here:
<font face="verdana" size="3" color="white"><div id="playing" style="height:25px;"></div><br></font>
If you need more info, comment please.

I'm trying to simply detect clicking an A link to display an Alert box. Whenever I place the script inside the php file my a link is located, it works fine, but whenever I place it in my custom JS file, it doesn't detect it, and I get the error 'Uncaught TypeError : Cannot set property "onclick" of null'.
The link between the php page and custom js page is definitely working, as I have previous working code on the page. It simply wont detect my A link it its located in an external script.
HTML
<a id="ConfirmHolidayClose" href="#">
<img src="assets/img/close-button.png" alt="Holiday-request-close-button"
class="CloseButton" />
</a>
JAVASCRIPT
document.getElementById("ConfirmHolidayClose").onclick=function(){
alert("Working");
}
UPDATE - Forgot to mention sorry, my a link is nested inside div called 'ConfirmHoliday'.
I have JS code manipulating the ConfirmHoliday div inside my Custom JS, so it cant be loading after because it is finding its parent div perfectly well at the moment.
The javascript file runs before the element is created, thus it doesn't exist. To solve this, you have couple options:
1) Surround the code with a window.onload function
window.onload = function () {
// Your code here
};
2) Put it in a separate js file and add a defer property to the script tag.
<script src="yourScript.js" defer="defer"></script>
3) Put the script tag after the anchor tag
It's trying to access the ConfirmHolidayClose element before it exists maybe? Where is your JS loaded in your page? I'm guessing in your <head>
A few solutions:
1) Move your script to bottom of page just above </body>
2) wrap your JS in dom ready function, this ensures no JS will run until the DOM tree exists. Easiest with jQuery, example below...
jQuery example
$(function() {
document.getElementById("ConfirmHolidayClose").onclick=function(){
alert("Working");
}
});
Vanilla example
document.addEventListener("DOMContentLoaded", function() {
document.getElementById("ConfirmHolidayClose").onclick=function(){
alert("Working");
}
});
I am using external JavaScript to show video player on web page like...
<script src='http://player.field59.com/v3/vp/...........'></script>
Here is my code that cut the HTML code which is generated by above script tag and paste into specific container like <div id='dynamic-video-container'></div>
$(document).ready(function(){
if( $("div.subscriber-hide div.html-content div.bimVideoPlayer").length ) {
var video_content = $('<span>').append($('div.subscriber-hide div.bimVideoPlayer').clone()[0]).remove().html();
}
$('div.subscriber-hide div.html-content').remove();
$("div#dynamic-video-container").html(video_content);
});
I am doing this because I am not able to put external code directly into "<div id='dynamic-video-container'></div>" container.
My issue is this sometimes play functionality of video player is not working may be due to loading sequence of external code and code snippet.
Is there any option by which code snippet will execute when external js becomes fully loaded? Can anyone suggest idea to how to do this?
One more thing external code "<script src='http://player.field59.com/v3/vp/...........'></script>" is added by CMS so I am unable to change this line.
Try this
window.onload = function() {
//your code comes here
}
As window.onload is called after all the content and resources of the page are loaded. Hope this helps.
So I am making a website for radio streams and was told I should use Jquery and AJAX to load the HTML files into a div on button click so that I wouldn't have to make the user load a completely new HTML page for each radio stream. But I am a bit lost since I am new to this language and I am not entirely sure what I am doing wrong.
Currently I have a index.html page that loads each individual div and loads all the available radio stations in an iframe linking to an HTML file. In this HTML file there are around 40 buttons that each have to link to their own radio stream. On a button press I want said stream to load into the 'radio player' div for a smooth transition.
After trying to google the problem I was told to do this with the following JavaScript code:
$(function(){
$(".538").click(function(){
$("#div3").load("/includes/about-info.html");
});
});
Since each button is also showing its own image file, I tried to add class="538 to each image source so the JavaScript knows what is targeted. Unfortunately it doesn't seem to work at all and I have no clue what to do. I tried to do this in a separate index.js file which unfortunately didn't work, so I tried to use the JavaScript code in the HTML file itself, and this didn't seem to do the trick either.
TL/DR: trying to load HTML code in a div when an image button is clicked.
Is there perhaps a tutorial for this available? I tried to search the web but couldn't find anything at all. If anyone is able to help me out with this problem I'd love you forever.
I think what's happening is that you're working with dynamic elements. More importantly you should never use numbers to start off either a class name or id.
Unless you post a bit more code it's hard to figure out exactly what you're wanting to do.
If you work with dynamic html the click event won't work, because well you need do dynamically bind the event listener.
For that you can use
$('#dynamicElement').on('click', function() {
$(this).find('#elementYouWantToLoadInto').load('/includes/about-info.html');
});
The above code works if the element is nested in the button. If it's an external element then use.
$('#dynamicElement').on('click',function() {
$('#elementYouWantToLoadInto').load('/includes/abount-info.html');
});
You mentioned that this language is a bit new to you; If you're open to a bit of refactoring:
Your main page should have 2 sections:
<div id='myButtons'>
<input type='radio' data-url='/includes/about-info.html' />
<...>
</div>
<div id='myContent'></div>
<script>
$(function() { //jquery syntax - waits for the page to load before running
$('#myButtons').on('click', 'input', function() { // jquery: any click from an input inside of myButtons will be caught)
var button = $(this),
url = button.data('url'),
content = $('#myContent');
content.load(url);
});
</script>
Jquery: http://api.jquery.com/
you can try this
$('#myButtons').on('click', 'input', function() {
$.get("about-info.html", function(data) {
$("#div3").html(data);
});
});
or
$(document).ready(function(){
$(function(){
$(".radio538").click(function(){
$("#div3").load("/includes/about-info.html");
});
});
})
$(document).ready(function(){
$('#radio1').on('click',function(){
#('#loadradiohere').load('/includes/about-info.html');
});
});
Try that code in your .js file. I am still working for a similar project man.
I'm trying to change the content of the portfolio section of my website. I have a div called .portfolio_box, which contains a small preview of the project (each project div also has a different id). When you click on this div (.portfolio_box) I want the content of the content div (#main_content) to go away and be replaced with the corresponding content.
I found the following tutorial and adjusted the script to my needs:
<script type="text/javascript">
$(document).ready(function()
{
$("#thomasschoof_old").click(function()
{
/*hide( 'fast', function()
{
$('#main_content').load(thomasschoof_old.html,'',showNewContent);
} );
var toLoad = $(this).attr('href')+' #main_content'; */
$('#main_content').hide('fast',loadContent);
$('#page').append('<span id="load">LOADING...</span>');
$('#load').fadeIn('normal');
});
function loadContent()
{
$('#main_content').load('thomasschoof_old.html #project','',showNewContent)
}
function showNewContent()
{
$('#main_content').show('normal',hideLoader);
}
function hideLoader()
{
$('#load').fadeOut('normal');
}
return false;
});
</script>
But when I click on the div #thomasschoof_old nothing happens. I don't know a lot about jQuery or Javascript (just getting into it) and I really can't get it figured out.
You can view the web page here: http://jowannes.com/thomasschoof/portfolio.html
I hope somebody can help me, Thanks in advance!

Your problem is, that you wrote your JS code inside scripts tags that are used to load an external script file (jQuery). You script just wont ge executed that way.
src: This attribute specifies the URI of an external script; this can
be used as an alternative to embedding a script directly within a
document. script elements with an src attribute specified should not
have a script embedded within its tags.
From: https://developer.mozilla.org/en-US/docs/HTML/Element/Script
Set up a separate script tag for you code or include it from a second external script-file and see what happens.
I have a webpage on which there a button.
On button press, I intent to embed a script in the head section of the page to enable a plugin. I can manually insert the snippet and my plugin but I want to be able to do this on button click itself to keep it as an optional element for my users.
What is the way to go about this?
As per #padde's query, the script looks like the following the way I include in my header:
<script type="text/javascript" src="http://code.abc.com/farfalla.js"></script>
<script type="text/javascript" src="http://code.abc.com/postmessage.js"></script>
Use createElement() of javascript and add it to the DOM
Check the below link for more information : http://www.hunlock.com/blogs/Howto_Dynamically_Insert_Javascript_And_CSS
If you are using jquery then you can use $.getScript to load the external js file.
$.getScript('filename.js',function(){
//your code ...
});
Normally, you would simply put the script inside the <head> tags. Then, extract the initializing code from the included script and run it when the button was clicked.
Edit
You can also try this:
HTML
<button id="share-button">Share this</button>
JavaScript
dynamicCode = 'alert("script loaded");'
scriptLoaded = false;
buttonClicked = function(e) {
if( !scriptLoaded ) {
var script = document.createElement('script');
script.text = dynamicCode;
document.getElementsByTagName('head')[0].appendChild(script);
scriptLoaded = true;
}
alert("thanks for sharing");
};
button = document.getElementById('share-button');
button.onclick=buttonClicked;
where you would load the dynamicCode with an Ajax call or whatever you like. The code is only loaded once. I've put together a jsfiddle for you, so you can try it out.
