I have TWO main questions that I really would have help with.
I have googled and searched for some day now without any help, but if you know any links that I maybe haven't watched or any site with help, then give me.
I would appreciated it, OR if you already have the code/sample code, would help :-)
I work with PhoneGap & JQuery Mobile right now, and the thing is this.
I have a 'textarea' there you write something, then a save button, what I want it to do is that when I press the save-button, the textvalue I wrote in the textarea would get saved in a listview in another page of the app. I have looked at "localstorage" but nothing works correctly.
(Also, if you write something in textarea and you press the cancel button, the text in the textarea should be deleted next time you go in to that page.)
The second question is:
When I press the save button, it should begin to count, in seconds, minutes, hours, days.
Think of it like this. I write "toothbrush" in the textarea and press save, now when I go to the listview-page, I can see it says toothbrush in the listview, beside the text it says 1m, 5m, 1h, it just update when it was last time I bought or changed the toothbrush, so next time I open the app, I can see "TOOTHBRUSH: 4Days, 16HRS, 52MINS AGO". In that way I can check when I bought something, or changed something.
This is my codes, both html & .js, what should I do so this mission will work.
Any suggestions, sites, or code you guys have that would help?
Thank you so much.

SOLUTION:
The JSFiddler code-example, the demo is perfect and are based on jQuery 1.9.1 & jQuery Mobile 1.3.0b1, I used 1.6.4 & 1.1.0.
After updating this two .js files, everything worked on PhoneGap!
Here is a DEMO
There are many questions within your problem, so I will probably not manage to answer all of them. To use localStorage with an array of 'tasks' you use JSON.stringify when saving and JSON.parse when retrieving.
So, each time page3 is displayed, you retrieve the current list of items from localStorage, create list items, empty the list and then append the created items :
$(document).on('pagebeforeshow', '#page3', function(){
//setup the current list
if(localStorage.getItem('TaskList')){
var TheList = [];
TheList = JSON.parse(localStorage.getItem('TaskList'));
var items = '';
for (var i = 0; i < TheList.length; i++) {
items += '<li><h3>' + TheList[i].text + '</h3><p>' + TheList[i].time + '<p></li>';
}
$('#orderedList').empty().append($(items)).listview('refresh');
}
});
When entering a new item, you want to store the text and the current time, so use an object. First get the current list from localStorage, then create the new item and add it to the list, finally save back to localStorage clear the textarea and navigate to page3. The cancel button just clears the textarea:
$(document).on('pageinit', '#page2', function(){
$('#btnCancel').on("click", function(){
$('#newItemText').val(''); //CLEAR TEXT AREA
});
$('#btnSave').on("click", function(){
var TheList = [];
if(localStorage.getItem('TaskList')){
TheList = JSON.parse(localStorage.getItem('TaskList'));
}
var newitem = $('#newItemText').val();
var task = {text: newitem, time: new Date() };
TheList.push(task);
localStorage.setItem('TaskList', JSON.stringify(TheList));
$('#newItemText').val(''); //CLEAR TEXT AREA
$.mobile.navigate( "#page3", { transition : "slide" });
});
});

This is the site in question: driglight.com/Learn5.html
The purpose of this site is to click the audio and then choose which image you believe to be the correct representation of the note that was played.
I want to randomize the audio and answers every time the page is refreshed.
When the audio is randomized I need to make sure that the audio that is chosen has it's matching correct answer of an image also chosen and placed randomly among the answers. Also,when any possible answer image is clicked, a div will appear that says 'Good Job!' or 'incorrect'. So when the correct answer is randomized it will need to have the 'Good Job' div to follow it.

I assume every audio fragment will have an image? So with that in mind, you create a random index to select an audio fragment (which you already do). Why don't you store that index in a variable and associate the image fragment with it?
Another option would be to create an object. So you make your array with audiofragments and then you initialize a new JS object, and assign the names of the images to 'properties' with your audiofragment as key. Like this:
var images = {};
images[audioname] = image-name;
***Do this for each audiofragment of course***
That way you can just ask the image from your images-object, using the property audioname.
When the page renders, place some value inside the attributes for the images or div:
<img id=myimage data-audio-file="xyz123.mp3" src="...." />
<div data-audio-file="xyz123.mp3" src="...." >My Content</div>
Read the attribute out when it's time to take some action:
var correctFile = $('#myimage').attr("data-audio-file");

At first sorry if i have some typing errors english is not my main language but i try to do my best to explain it at my best.
I am working on a test app with a note database.
It works fine with adding and deleting but there is a small problem...
At the moment that i add a note (on edit.html) and want to go back to the index.html page it is not going back.
i am working with multiple data-page-role pages so each page has his own id.
The code that i use for the note database:
index.html Header:
$("#homePage").live('pageinit', function() {
init();
});
index.html data-page-role

And here is the backend code that i use for the note database
document.addEventListener("deviceready", onDeviceReady, false);
function onDeviceReady() {
phoneready();
}
function setupTable(tx){
tx.executeSql("CREATE TABLE IF NOT EXISTS notes(id INTEGER PRIMARY KEY,title,body,updated)");
}
function getEntries() {
dbShell.transaction(function(tx)
{
tx.executeSql("select id,title,body, updated from notes order by id asc", dbErrorHandler, renderEntries)
}, function(){ alert ("Error getentries");
});
}
function renderEntries(tx,results){
if (results.rows.length == 0) {
$("#mainContent").html("<p>Je hebt nog geen notities.</p>");
} else {
var s = "";
for(var i=0; i<results.rows.length; i++) {
s += "<li><a href='edit.html?id="+results.rows.item(i).id + "'>" + results.rows.item(i).title + "</a></li>";
}
$("#noteTitleList").html(s);
$("#noteTitleList").listview("refresh");
}
}
function saveNote(note) {
//Sometimes you may want to jot down something quickly....
if(note.title == "") note.title = "[Geen Titel]";
dbShell.transaction(function(tx) {
if(note.id == "")
{
tx.executeSql("insert into notes(title,body,updated) values(?,?,?)",[note.title,note.body, new Date()]);
}
else
{
tx.executeSql("update notes set title=?, body=?, updated=? where id=?",[note.title,note.body, new Date(), note.id]);
}
}, function(){ alert ("Error savenote");},
function()
{
window.navigator.location("index.html#homePage");
});
}
function DeleteNote(id){
dbShell.transaction(
function(tx)
{
tx.executeSql('Delete FROM notes where id=' + id);
},
function(){ alert ("Error deletenote");},
function(err)
{
window.navigator.location("index.html#homePage");
});
}
function phoneready(){
dbShell = window.openDatabase("SimpleNotes", 2, "SimpleNotes", 1000000);
setupTable();
}
function init(){
getEntries();
//edit page logic needs to know to get old record (possible)
$("#editPage").live("pagebeforeshow", function() {
//get the location - it is a hash - got to be a better way
var loc = window.location.hash;
if(loc.indexOf("?") >= 0) {
var qs = loc.substr(loc.indexOf("?")+1,loc.length);
var noteId = qs.split("=")[1];
//load the values
dbShell.transaction(
function(tx) {
tx.executeSql("select id,title,body from notes where id=?",[noteId],function(tx,results) {
$("#noteId").val(results.rows.item(0).id);
$("#noteTitle").val(results.rows.item(0).title);
$("#noteBody").val(results.rows.item(0).body);
});
}, dbErrorHandler);
}
});
}
As u can see at saveNote and on deleteNote i call the function window.navigator.location("index.html#homePage");
I did this as far as i tried with $.mobile.changePage("index.html#homePage"); it will go back but then it won't run the init(); function at the header script.
I hope i explained it all correct and if there are any questions please let me know.
I will try then to do my best at explaining it.
edit:
More information:
At first thank you for your answer, i got multiple data-role-pages.
A extra example:
<div data-role="page" id="page5" data-add-back-btn="true">
<!-- Header -->
<div data-role="header" >
<h1>Locatie</h1>
</div>
<!-- Main content div -->
<div data-role="content">
<p id="geolocation" onClick="onDeviceReady()">Op zoek naar uw locatie ...</p>
<img src="" id="map" width="100%" height="" />
<h4>Omgeving</h4>
<img src="" id="map2" width="100%" height="" />
</div>
<div data-role="footer" id="footer"> <img src="a12.png" />
<p>© 2012 - Swen Kooij / Paksha Thullner / Johnny Jansen</p>
</div>
</div>
You are trying to change page with deep link "index.html#homePage" .
JqueryMobile does not support that. When you pass a file, he will load ONLY the first page of that file.
This means that when you pass "index.html#homePage", he'll only consider the "index.html" and load the first page on that file.
I don't know it for sure, but if in your index.html file only have the "homePage", change function window.navigator.location to:
$.mobile.changePage("index.html")
And of course do the same for the anchor tag .
I use:
window.location = "#home";
I have four divs, each div contain images and contents. one next and previous button. at a time only div will show. on click of next the second div have to be shown and first will hide. same upto fourth div. Need to use pure Javascript. No jquery or javascript plugins is allowed.... :(. Can anyone help me to do this?.
Thanks!

I think this is what you are loking for:
http://girlswhogeek.com/tutorials/2007/show-and-hide-elements-with-javascript
But you could put that in one function:
<script language="JavaScript">
function ShowHide(divId){
if(document.getElementById(divId).style.display == 'none')
{
document.getElementById(divId).style.display='block';
}
else
{
document.getElementById(divId).style.display = 'none';
}
}
</script>
function toggleImage(forwrad){
var imageConainer = document.getElementByID(Your Parent div id);
var images = imageContainer.childNodes;
var showIndex = '';
for(var i=0; i<images.length;i++){
if(images[i].style.display == 'block'){
images[i].style.display == 'none';
if(forwrad){
showIndex = 1+1;
}
else{
showIndex = 1-1;
}
}
}
images[showIndex].style.display = true;
}
technically it's possible with pure CSS as well. with the :target pseudo class. but that would pollute your url with # tags. But you may actually want that.
Also Selectivizr is a good polyfill for old browsers
I have this code, it works for a rotating menu that is obviously a ul> li> Menu.
What I would like to know is how to trigger (onClick, HRef, etc.) the function for a specific list item such as rot7.
I would like to click a line of text and fire the function, is this possible?
Example "Click here to go there" ,
Kinda like the old days -- {a href="some.html"}Click Here{/a} page loads.
In this case I want the text to open the 7th li> menu item using the form and function of the JQuery script.
There, clear as Mud.

EDIT:
The code above will not work because each time the menu is changing pages sets the container (.description) content with the original tags get upon initialization, so the page content including our a tag is overriden by a the original content which is same as previous one, but overrides the old one and that's why the click handler doesn't work - because it was set on an item which is overriden.
To not set the click handler each time when the menu changes the pages it should be bind into the link as simple as taht: <a onclick="$('#rotmenu li:nth-child(6)').click();" href="javascript:;">Book now to schedule your Complimentary Consultation</a>.
That's it - works fine.
