Why does this work in jsfiddle but not in my document
Question
I found a wonderful jsfiddle that someone has made and wanted to use part of it in my project:
http://jsfiddle.net/manuel/29gtu/
It works on the jsfiddle but not in my HTML document. Here is what in my document:
<!DOCTYPE html>
<html>
<head>
<script src="scripts/jquery-1.7.2.js"></script>
<script>
$("button").click(function() {
var id = $("#id").val();
var text = "icon-"+id;
// update the result array
var result = JSON.parse(localStorage.getItem("result"));
if(result == null)
result = [];
result.push({id: id, icon: text});
// save the new result array
localStorage.setItem("result", JSON.stringify(result));
// append the new li
$("#bxs").append($("<li></li>").attr("id", "item-"+id).html(text));
});
// on init fill the ul
var result = JSON.parse(localStorage.getItem("result"));
if(result != null) {
for(var i=0;i<result.length;i++) {
var item = result[i];
$("#bxs").append($("<li></li>").attr("id", "item-"+item.id).html(item.icon));
}
}
</script>
</head>
<body>
<ul id="bxs" class="tabs">
</ul>
<input type="text" id="id" /><button>save</button>
</body>
</html>
The code is copied and pasted from the fiddle. I think it has to do with me not having a plugin for local storage. For that jsfiddle to work, do I need some external plugin that I am missing?

You should wrap your whole code within $(document).ready(function() {...});
So.
<script type="text/javascript">
$(document).ready(function() {
$("button").click(function() {
var id = $("#id").val();
var text = "icon-" + id;
// update the result array
var result = JSON.parse(localStorage.getItem("result"));
if (result == null) result = [];
result.push({
id: id,
icon: text
});
// save the new result array
localStorage.setItem("result", JSON.stringify(result));
// append the new li
$("#bxs").append($("<li></li>").attr("id", "item-" + id).html(text));
});
// on init fill the ul
var result = JSON.parse(localStorage.getItem("result"));
if (result != null) {
for (var i = 0; i < result.length; i++) {
var item = result[i];
$("#bxs").append($("<li></li>").attr("id", "item-" + item.id).html(item.icon));
}
}
});
</script>
Note
In jsfiddle onLoad mode do that for you, ie when you select onLoad from left side panel drop down, then all js code execute after all resources become appeared in the DOM.

Put in $(document).ready like this, Also give type of script tag
<script type="text/javascript">
$(document).ready(function() {
$("button").click(function() {
var id = $("#id").val();
var text = "icon-" + id;
// update the result array
var result = JSON.parse(localStorage.getItem("result"));
if (result == null) result = [];
result.push({
id: id,
icon: text
});
// save the new result array
localStorage.setItem("result", JSON.stringify(result));
// append the new li
$("#bxs").append($("<li></li>").attr("id", "item-" + id).html(text));
});
// on init fill the ul
var result = JSON.parse(localStorage.getItem("result"));
if (result != null) {
for (var i = 0; i < result.length; i++) {
var item = result[i];
$("#bxs").append($("<li></li>").attr("id", "item-" + item.id).html(item.icon));
}
}
});
</script>
