How to retrieve shopping cart items, implementing LocalStorage

How do I retrieve information stored in a js file? I assume I am labelling my node elements in HTML incorrectly
I'm hoping to gain a better understanding of how to retrieve a function node from localStorage
Below are the key factors I am trying to get using getElementById into local storage from post HTML.
This is not everything in my listing.html document, I have excluded everything but what I think are essential elements
<div class="listing">
<div class="container-form">
<div class="mySlides fade">
<div class="numbertext">1 / 3</div>
<img class="img" value(src)="1" id="img" src="images/4.JPG" alt="img1">
</div>
<div class="infoBox">
<h5 post="weight" id="weight" value="7.00">7.00 : Under - 16 oz</h5>
</div>
<div class="column-bottom">
<div class="add-button">
<div class="add-button" method="post">
<p><input type="submit" onclick="addListing()" class="btn"></input></p>
<div class="buy-button">
<span class="price" post="price" id="price" value="60">$60</span>
<button type="button" class="btn" onclick="window.location.href='cart.html'" onclick="addListing()"
;>BuyMe</button>
</div>
</div>
</div>
</div>
</div>
</div>
I am trying to use the function below to store each element from the post HTML
function addlisting() {
let listing = ['listings'];
if (localStorage.getItem('listings')) {
listing = JSON.stringify(localStorage.getItem('listings'));
alert("added!");
}
listing.push({ 'listingId': listingId + 1, image: '<imageLink>' });
listingsId = listingsId + 1;
var listingsName = document.getElementById('name').innerHTML;
var listingsPrice = document.getElementById('price').getAttribute('data- value');
var listingsImage = document.getElementById("img").src;
var listingsWeight = document.getElementById('weight').getAttribute('data- value');
value = parseFloat(listingsPrice, listingsWeight).toFixed(2);
localStorage.getItem('name', 'price', 'img', 'weight', JSON.stringify(listingsName, listingPrice, listingsImage, listingsWeight));
}
here is the $(document).ready(function(){ function I'm hoping to implement into my code, I got this from another Stack Overflow page as it was the most fitting however I am yet to understand each component.
$(document).ready(function () {
$('#Btn').load(function () {
let listings = [];
if (localStorage.getItem('listings')) {
listings = JSON.parse(localStorage.setItem('listings'));
}
listings.push({ 'listingId': 1, image: '<imageLink>' });
});
});
my question again is how do I then execute this function using onload Onto a separate HTML, called cart.html. I did not display my cart.html file because there is nothing pertaining to this question on it. And furthermore how to go about styling Onload events that retrieve information from localStorage.
P.S.
There is an alert function within my first .js excerpt addListing(), that does not fire when clicked. probably a sign of bad programming. I've just never found a straightforward answer

Attempting to replace an audio src value on click?

I'm trying to program a playlist for a site I'm presently working on, and I'm having some issues presently. I've written the script so far and it replaces the default song with a second song, but does not revert back on click.. any suggestions?
The HTML...
<audio id="player" src="../audio/small-skeletal.mp3" type="audio/mp3" controls autoplay></audio>
<div id="audio_list" style="margin-top: 100px;">
<div id="track">
<h2 class="change-song" data-track="http://www.birp.fm/music/playlists/2014/january-2014/027%20-%20Phantogram%20-%20Fall%20In%20Love.mp3">Switch to second song</h2>
<h2 id="bb" class="change-song" data-track="http://www.logicwebmedia.com/dev/ecb/new-dev/audio/small-skeletal.mp3">Change it back!!</h2>
</div>
$('.change-song').click(function(){
var song = $('.change-song').data('track');
$('#player').attr('src', song).attr('autoload', 'auto').attr('autoplay');
});
The script only ever returns the first song as the value, and never the second.. how do I fix this?

Change your click function to:
$('.change-song').click(function(){
var song = $( this ).data('track');
$('#player').attr('src', song).attr('autoload','auto').attr('autoplay');
});
this is a reference to the element that was clicked.

You need to use this as a reference to the clicked .change-song element in the click handler. Your current code is selecting both elements at once and when you retrieve the track data attribute it only gets it from the first element in the matched set.
$('.change-song').click(function(){
var song = $(this).data('track');
$('#player').attr('src', song).attr('autoload','auto');
});

Change your $('.change-song').data('track'); to $(this).data('track'); which will give you correct scope. Sorry for changing song files in the snippet.
$('.change-song').click(function() {
var song = $(this).data('track');
$('#player').attr('src', song).attr('autoload', 'auto').attr('autoplay');
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="buttonmit2ani">
<audio id="player" src="audio/acdc.ogg" controls autoplay></audio>
<div id="audio_list" style="margin-top: 100px;">
<div id="track">
<h2 id="aa" class="change-song" data-track="audio/acdc.ogg">Switch to second song</h2>
<h2 id="bb" class="change-song" data-track="audio/radiohead.ogg">Change it back!!</h2>

Javascript Selecting child element not working

i m working on adding a FB share button to all my posts.
so i wanted to use the sharer.php? method with all the parameter retrieved from the post.
So my blog structure
<div id='postwrapper'>
<div id='title'>
hello</a>
</div>
<div id='da'>
<span>Posted on </span>
<span class='divider'></span>
<span>By</span>
</div>
<div class='post_content'>$row['post'] gud day</div>
<div id='post_footer'>
<a href=viewpost.php>Continue reading</a>
<a href='#' onClick='fbshare(this)'>Insert text or an image here.</a>
</div>
</div>
My javascript for fbshare function (not complete).
function fbshare(fb) {
var p1 = fb.parentNode;
var p2 = p1.parentNode;
var title = p2.getElementById("title").innerHTML;
alert(title);
}
Everytime i try this it says undefined is not a function

getElementById is a function of the document. Assuming you have more than one post on the page (ids must by unique), try using a class instead:
<div class='title'>
And using getElementsByClassName:
var title = p2.getElementsByClassName("title")[0].innerHTML;

play pause multiple vimeo videos

I have found a solution to starting/pausing multiple vimeo videos from seperate buttons, but I would like to use images for the play and pause buttons.
Can anyone help me ammend the code? I guess I need to replace the html button code with images and then reference them in the javascript, but I can't seem to get it to work.
Many thanks.
my html is:
<div>
<h1>Player 1</h1>
<div class="api_output"></div>
<iframe id="player_1" src="http://player.vimeo.com/video/7100569?js_api=1&js_swf_id=player_1" width="500" height="281" frameborder="0"></iframe>
<button class="simple" id="api_play">Play</button>
<button class="simple" id="api_pause">Pause</button>
</div>
</div>
<div>
<div>
<h1>Player 2</h1>
<div class="api_output"></div>
<iframe id="player_2" src="http://player.vimeo.com/video/3718294?js_api=1&js_swf_id=player_2" width="500" height="281" frameborder="0"></iframe>
<button class="simple" id="api_play">Play</button>
<button class="simple" id="api_pause">Pause</button>
</div>
</div>
The javascript is:
var VimeoEmbed = {};
VimeoEmbed.init = function(e)
{
//Listen to the load event for all the iframes on the page
$('iframe').each(function(index, iframe){
iframe.addEvent('onLoad', VimeoEmbed.vimeo_player_loaded);
});
};
VimeoEmbed.vimeo_player_loaded = function(player_id)
{
$('#'+player_id).prev('.api_output').append('VimeoEmbed.vimeo_player_loaded ' + player_id+'<br/>');
var loop = 0;
var volume = 100;
//Simple Buttons
$('#'+player_id).nextAll('button.simple').bind('click', {'player_id': player_id}, function(e){
var iframe = $('#'+e.data.player_id).get(0);
iframe.api( $(e.target).attr('id'), null );
});
//API EVENT LISTENERS
VimeoEmbed.setupAPIEventListeners($('#'+player_id).get(0));
};
//On document ready
$(document).ready(VimeoEmbed.init);

I think it'll be something like this
<div>
<h1>Player 1</h1>
<div class="api_output"></div>
<iframe id="player_1" src="http://player.vimeo.com/video/7100569?js_api=1&js_swf_id=player_1" width="500" height="281" frameborder="0"></iframe>
<img class="simple" id="api_play" src="play.png">
<img class="simple" id="api_pause" src="pause.png">
<!-- ... same for player 2 -->
And in the js
VimeoEmbed.vimeo_player_loaded = function(player_id)
{
$('#'+player_id).prev('.api_output').append('VimeoEmbed.vimeo_player_loaded ' + player_id+'<br/>');
var loop = 0;
var volume = 100;
//Simple Buttons
$('#'+player_id).nextAll('img.simple').bind('click', {'player_id': player_id}, function(e){
var iframe = $('#'+e.data.player_id).get(0);
iframe.api( $(e.target).attr('id'), null );
});
//API EVENT LISTENERS
VimeoEmbed.setupAPIEventListeners($('#'+player_id).get(0));
};

how to hide/remove all text in-between two elements?

lets say i have this lump of HTML:
<div class="container">
<span class="title">Heading 1</span>
This is a description..<br />
This is the second line..
<div class="image"><img src="image.jpg" /></div>
</div>
What i want to do using jQuery/JavaScript is hide/remove all text and elements between <span class="title"> and <div class="image">.
I've looked all over and found pretty much nothing. Any ideas on how i could do this?

How about something like this? http://jsfiddle.net/ZW8q2/1
var foo = $('.container').children(':not(br)');
$('.container').html('').html(foo);

You could try:
var str = $('.container .title').text() + $('.container .image').html();
$('.container').html(str);
JS Fiddle.

Try this:
Place a tag around what you want to hide, give div an ID name. So in the end your will look like:
<div id = "hideMe" style ="display:block">...Your Content...</div>
Use this javascript:
function hide()
{
document.getElementById('hideMe').style.display = "none";
return;
}
Have the Javascript function called whenever you want to hide the stuff between the div from a button (or other control) like this:
<input type= "submit" onclick ="hide()">
