I am fairly new to JS and i thought i understood the order in which the components of the page are loaded but this puzzles me.
I'm working with foundation 5 and i am using an accordion component. In my js script i load data and put it into an accordion which then becomes the inner html of the mainContainer div.
<link rel="stylesheet" href="css/foundation.complete.css">
<link rel="stylesheet" href="css/normalize.css">
<link rel="stylesheet" type="text/css" href="css/myCss.css" />
<script src="js/vendor/modernizr.js"></script>
<script src="js/app.js"></script>
<script src="js/vendor/jquery.js"></script>
<body onload="iniciarPg()">
<div id="principal" class="mainContainer">
<dl class="accordion" data-accordion > </dl>
</div>
function iniciarPg()
{
$(document).foundation({
accordion: { toggleable: true }
});
loadData();
}
</script>
<!--SCRIPTS -->
<script src="js/classie.js"></script>
<script src="js/foundation.min.js"/>
<script src="js/foundation/foundation.accordion.js"/>
</body>
The part i cannot comprehend is that although all the inner HTML of the mainContainer gets replaced, if i delete <dl class="accordion" data-accordion > </dl> from my html, then when the JS loads, the page does no display the accordeon correctly, it does not expand when clicked.
You need to reflow your foundation plugin as the data comes later through ajax.
function iniciarPg()
{
$(document).foundation({
accordion: { toggleable: true }
});
loadData();
//make sure the ajax has been finished and the HTML is properly set, otherwise move following line to you ajax success handler end.
$(document).foundation('reflow');
}
</script>

The sample code below loads a page with a "Show 3D" clickable div. Onclick, it should load a 3D viewer and display associated data.
function showPDB(path,id) {
var stage = new NGL.Stage(id, {backgroundColor:'white'});
stage.loadFile(path).then(function (o) {
o.addRepresentation("cartoon", {color: 'white' });
o.autoView();
});
};

It seems that "Show 3D" needs to be clicked twice for the 3D viewer to load. I would like it to load upon a single click.
I guess this function should be triggered only when the inside of the collapsible element has been fully loaded. I tried to tweak in this direction but I could not find a fix yet.
As it is a collapsible, just give some time to the collapsible to load. TO do that, you can wrap the entire script inside a set timeout like below
function showPDB(path,id) {
setTimeout(() => {
var stage = new NGL.Stage(id, {backgroundColor:'white'});
stage.loadFile(path).then(function (o) {
o.addRepresentation("cartoon", {color: 'white' });
o.autoView();
});
});
};
I have a div that serves of container for a css animation that appears over the entire website's home page... a text and background that opens like curtains, revealing the website under it. It's like an intro landing page. The thing is I need it to appear only on first page load. I don't want it to appear on page refresh or if someone navigates thru the site and comes back to home page.
Can someone please show me how I would have to code this because I've search a lot on the web and didn't find any clear explanations for my particular case.
Here is the code for the div:
<div id="landContainer">
<div class="left-half" id="leftP"><article class="leftPanel"><img id="SloganLeft" src="Decouvrez.svg"></article></div>
<div class="right-half" id="RightP"><article class="rightPanel"><img id="SloganRight" src="Atteignez.svg"></article></div>
</div>
So the div I must display only on first page load would be the one with the ID landContainer, that contains a couple of other divs.
Since I'm new to this type of coding, I would need a complete example of the code I need to use with my div.

The best way is to use session through which you can determine if its a new request or old.
Server side session will be best here
$( document ).ready(function() {
var isExists = localStorage.getItem("pageloadcount");
if (isExists != 'undefined') { $("#landContainer").hide();
}
localStorage.setItem("pageloadcount", "1");
});
<div id="landContainer">
<div class="left-half" id="leftP">
<article class="leftPanel"><img id="SloganLeft" src="Decouvrez.svg"></article>

<div class="right-half" id="RightP">

I am having trouble resetting jQuery UI sliders.
I get this error:
MyProject.OrderInfo.Search.js:187 Uncaught TypeError: $(...).slider is not a function
I think our problem has something to do with having multiple jQuery/Javascript libraries, stepping over each other, but I am uncertain. Everything my team has been trying has not worked. We simply need to reset our sliders to have NULL values. We need to use NULL, so that we know the user has not touched the slider. That way, we can exclude it from our API call parameters.
How can I reset the slider values to NULL?
Here is what the code looks like:

[MyProject.OrderInfo.Search.js] (a .JS file for searching Orders REST API):
//Declare slider variables as null and assign only in change function, to distinguish 'dirty' slider from a 'clean' slider

Notice there are references to:

<script src="//code.jquery.com/jquery-1.10.2.js"></script>
<script src="//code.jquery.com/ui/1.11.4/jquery-ui.js"></script>
We have to do this because our BackgridJS implementation uses jQuery 2.2.
The sliders want to use 'jquery-ui.js', which I believe depends upon 'jquery-1.10.2.js'.
When the user clicks the Reset button, the error occurs and javascript acts like the slider isn't loaded. But it is, I can see it working in the UI. Could it be that the Reset button event needs to move somewhere else?
Any ideas? Help?
UPDATE #1:
I tried #Noctane's suggestion, but I still get the same error, no matter where I put the Reset function. I can put it inline, I can put it in other scripts but it just never works unfortunately.

I have prepared a demo using jsFiddle, that uses jquery UI while utilizing both jquery v2.2.0 and jquery version 1.10.2, please have a look, you will see that as you move the slider it will set its changed value to the console, when you click reset it will set the slider to null.

You may need to re-arrange your includes in your application to get it to work. If you re-arrange the ones in the fiddle you will see the error you are getting, if you then switch them back to the way I have them arranged you will see it work.
I have created a VERY simple program on a VERY simple html file. I wish to simply find out how to link javascript to html and css. Here follows my example code:
(index.html)
<head>
<title>JavaScript</title>
<link rel="stylesheet" href="stylesheet.css"/>
</head>
<body>
<div class="picture">
<img src="https://encrypted-tbn1.gstatic.com/images?q=tbn:ANd9GcRZAb6KcZrNTBM1UflIMAQfAGuTKN0XWYFsiTgm5M5NRwXO_udT"/>
</div>
<button class="show_btn">Show</button>
<button class="hide_btn">Hide</button>
<script src="script.js"></script>
</body>
JS:
$(document).ready(function(){
$(".hide_btn").click(function(){
$("p").slideUp();
});
$(".show_btn").click(function(){
$("p").slideDown();
});
});
CSS:
.picture { display: none; }
Now with this code, I am attempting to use two buttons to show and hide a picture of a fish...I can't seem to get it to work however, and I believe it has something to do with how I am linking my files. Please Help!
Based off of your comment in your question it would appear that you are using jQuery but you do not have jQuery as part of your source code.
You will need to include the jQuery source above script.js.
Here is an example of how it should look like using Google CDN for the jQuery library:
<head>
<title>JavaScript</title>
<link rel="stylesheet" href="stylesheet.css"/>
</head>
<body>
<div class="picture">
<img src="https://encrypted-tbn1.gstatic.com/images?q=tbn:ANd9GcRZAb6KcZrNTBM1UflIMAQfAGuTKN0XWYFsiTgm5M5NRwXO_udT"/>
</div>
<button class="show_btn">Show</button>
<button class="hide_btn">Hide</button>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
<script src="script.js"></script>
</body>
try this in javascript
<html>
<head>
</head>
<body>
<div class="picture" id="picture">
<img src="https://encrypted-tbn1.gstatic.com/images?q=tbn:ANd9GcRZAb6KcZrNTBM1UflIMAQfAGuTKN0XWYFsiTgm5M5NRwXO_udT" />
</div>
<button class="show_btn" onclick="show();">Show</button>
<button class="hide_btn" onclick="hide();">Hide</button>
<script type="text/javascript" >
function show(){
var imgdiv = document.getElementById("picture");
imgdiv.style.display="block";
}
function hide(){
var imgdiv = document.getElementById("picture");
imgdiv.style.display="none";
}
</script>
</body>
</html>
I would definitely use jQuery for something like this. Here's a Plunker that shows how you can accomplish this.
http://embed.plnkr.co/DwTwNuF162rfgcQOdT7u/preview
<html>
<head>
<script data-require="jquery#*" data-semver="2.1.3" src="http://code.jquery.com/jquery-2.1.3.min.js"></script>
<link rel="stylesheet" href="style.css" />
<script src="script.js"></script>
</head>
<body>
<div class="picture" id="picture">
<img src="https://encrypted-tbn1.gstatic.com/images?q=tbn:ANd9GcRZAb6KcZrNTBM1UflIMAQfAGuTKN0XWYFsiTgm5M5NRwXO_udT" />
</div>
<button class="show_btn" onclick="show()">Show</button>
<button class="hide_btn" onclick="hide()">Hide</button>
</body>
<script>
function show() {
$('#picture').show();
}
function hide() {
$('#picture').hide();
}
</script>
</html>
If you are using jquery you also need to link the jquery source above your .js link,
here is the google cdn (so you dont have to download it):
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
First things first:
Include this in your <head>:
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
If you're on Chrome try using the developer tools; right click on the page then inspect element. On the developer tools pane, select the CONSOLE tab which logs all your errors in your javascript
And try this in your script:
$(document).ready(function() {
$(".show_btn").click(function() {
$(".picture").css('display', 'block');
});
$(".hide_btn").click(function() {
$(".picture").css('display', 'none');
});
});
Also I've noticed that you have div.picture display set to "none".
All that you need to do is the following
<script type="text/javascript"></script>
You can write javascript inside the script tags. (if you want to add javascript in HTML
the following is to link it to another file.
<script src="path to other file" > </script>
I built my application from scratch for the past few weeks.
I did it while implementing the instructions here.
I have to say that everything works great with any normal browser such as Mozilla or Chrome, and the Angular.js framework has been of much use to me.
The problem is that with IE8, everything seems to be broken, and the document.createElement
DOM object throws an errro when I try to create an element for my custome directive(which I'm also using an 'x-' prefix for, as required by this lame excuse of a btowser).

You should read this article about using Angular with IE8 and earlier. There are some tricks you need to know about. Whenever I target IE8 with Angular, I avoid writing element directives and stick with attribute directives instead.
