Adding an item to the top of a Dojo Select dijit, but can't select the second item

I have two Select dijits that are based off the same data store. The first dijit is the required response and the second dijit is an optional response. For the second dijit, I want to add the additional item "None" to the top of the list. However, when I do that, I cannot select the second item in the list. In this JSBin, if you select "General lakebed mapping" in the second dijit, the returned value is the added item "None".
require(["dijit/form/Select",
"dojo/data/ObjectStore",
"dojo/store/Memory",
"dojo/domReady!"
], function (Select, ObjectStore, Memory) {
var data = [
{ id: 0, label: 'General lakebed mapping' },
{ id: 1, label: 'Bathymetry/Digital Elevation Model' },
{ id: 2, label: 'Ferrous object detections/magnetic anomalies' },
{ id: 3, label: 'Ground-truth data' },
{ id: 4, label: 'Lakebed color' },
{ id: 5, label: 'Lakebed surface type, hardness/smoothness/slope' },
{ id: 6, label: 'Sub-bottom geology' }
];
var store = new Memory({
data: data
});
var os = new ObjectStore({ objectStore: store });
var s = new Select({
store: os,
sortByLabel: false
}, "target");
s.startup();
data.unshift({ id: -1, label: 'None' })
store.setData(data);
var s1 = new Select({
store: os,
sortByLabel: false
}, "target1");
s1.startup();
s1.on("change", function () {
console.log("my value: ", this.get("value"))
});
})

Do not use the value 0 as an id. It is a falsey value in JavaScript and I suspect that the Select dijit source treats it somewhere as false and fails. Just use another value in its place.

How to fiddle an easy OnDemandList (dgrid)?

I have tried to create a very simple jsfiddle to test an OnDemandList (sitepen/dgrid). But it does not render any rows. Does anybody have an idea what I have done wrong? Is it that a simple dstore/Memory does not offer methods like fetchRange? The jsFiddle can be found here: http://jsfiddle.net/rbeqqr2g/25/
require({
packages: [
{
name: 'dgrid',
location: '//cdn.rawgit.com/SitePen/dgrid/v0.3.16'
},
{
name: 'xstyle',
location: '//cdn.rawgit.com/kriszyp/xstyle/v0.2.1'
},
{
name: 'put-selector',
location: '//cdn.rawgit.com/kriszyp/put-selector/v0.3.5'
},
{
name: 'dstore',
location: '//cdn.rawgit.com/SitePen/dstore/master'
}
]
}, [
'dgrid/OnDemandList',
'dstore/Memory',
'dojo/dom',
], function(OnDemandList, Memory, dom) {
var data = [
{ id: 1, name: 'Peter' },
{ id: 2, name: 'Paul' },
{ id: 3, name: 'Mary' }
];
var store = new Memory({
data: data
});
var list = new OnDemandList({
collection: store,
minRowsPerPage: 5,
noDataMessage: "Keine Daten vorhanden",
renderRow: function (object, options) {
console.log("Zeile wurde gerendert.")
var div = document.createElement('div');
div.appendChild(document.createTextNode(object.name));
return div;
}
}, dom.byId('list'));
list.startup();
});

You're using the most recent dstore, but an old dgrid. The < 1.x versions of dgrid did not support dstore, you can use a regular dojo/store/Memory instead. In dgrid < 1.x, you also needed a store property instead of collection.
require({
...
}, [
'dgrid/OnDemandList',
//'dstore/Memory',
'dojo/store/Memory', // < --- regular dojo/store
'dojo/dom',
], function(OnDemandList, Memory, dom) {
...
...
var list = new OnDemandList({
//collection: store,
store: store, // <--- store property
...
}, dom.byId('list'));
list.startup();
});
http://jsfiddle.net/rbeqqr2g/28/
Alternatively, unless you're stuck with dgrid 0.3.x, you can also simply use the modern dgrid:
{
name: 'dgrid',
location: '//cdn.rawgit.com/SitePen/dgrid/v1.1.0'
//location: '//cdn.rawgit.com/SitePen/dgrid/v0.3.16'
},

Getting id or name of folder in fuelux tree

I'm trying to get the id or name of the selected folder in a fuelux tree but couldnt manage to get it done.
My tree is a classic folder/file type tree and I want to be able to see the id of the folder when I click on a file.
this is my datasource for tree
var treeDataSource = new DataSourceTree({
data: [
{ name: 'Elektronik Belgelerim', type: 'folder', 'icon-class': 'blue', additionalParameters: { id: 'F1' } },
{ name: 'Gelen Kutusu', type: 'folder', 'icon-class': 'blue', additionalParameters: { id: 'F2' } },
{ name: 'Giden Kutusu', type: 'folder', 'icon-class': 'blue', additionalParameters: { id: 'F3' } },
{ name: 'Çöp Kutusu', type: 'folder','icon-class':'green', additionalParameters: { id: 'I1' } },
//{ name: 'Çöp Kutusu', type: 'item', 'icon-class': 'success', additionalParameters: { id: 'F4' } },
//{ name: 'Reports', type: 'item', additionalParameters: { id: 'I1' } },
//{ name: 'Finance', type: 'item', additionalParameters: { id: 'I2' } }
],
delay: 400
});
js function for tree begins like this inside tree-custom.js
var e = function (e, i) {
this.$element = t(e), this.options = t.extend({}, t.fn.tree.defaults, i), this.$element.on("click", ".tree-item", t.proxy(function (t) {
this.selectItem(t.currentTarget)
}, this)), this.$element.on("click", ".tree-folder-header", t.proxy(function (t) {
this.selectFolder(t.currentTarget)
}, this)), this.render()
};
and this is where I add the links under folders again inside trree-custom.js. Very primitive I know but that's all I can do with my current skillset. The part I added is between quotes. Rest came with beyondadmin theme and looks like usual fuelux.
selectFolder: function (e) {
//alert("testselectFolder");
//
//alert($('#myTree').tree({ dataSource: dataSource }));
var i, n, r, o = t(e),
s = o.parent(),
a = s.find(".tree-folder-content"),
l = a.eq(0);
//-----------------------------------------------
var li = $('<li>');
var TcgbLink = $('<a href=/E-Belge/Main/Folder/Inbox/?Type=1&DocumentTypeId=3>e-TCGB</div>' +"</br>");
var FaturaLink = $('<a href=/E-Belge/Main/Folder/Inbox/?Type=1&DocumentTypeId=4>e-Fatura</div>' + "</br>");
var Dolasim = $('<a href=>e-Dolasim Belgesi</div>');
li.append(FaturaLink);
a.append(li);
li.append(TcgbLink);
a.append(li);
li.append(Dolasim);
a.append(li);
//-----------------------------------------------
o.find(".fa.fa-folder").length ? (i = "opened", n = ".fa.fa-folder", r = "fa fa-folder-open", l.show(), a.children().length || this.populate(o)) : (i = "closed", n = ".fa.fa-folder-open", r = "fa fa-folder", l.hide(), this.options.cacheItems || l.empty()), s.find(n).eq(0).removeClass("fa fa-folder fa-folder-open").addClass(r), this.$element.trigger(i, o.data())
},
Now these links are being generated under all 4 folders. I want to be able to get the id (or name, preferably Id) of the folder so I can assign new Type parameters to querystring.
So far I tried to reach the id with this.data.id to no avail.

Instead of injecting the folder's children in the selectFolder callback, it is recommended to add the children via the dataSource callback (as in this example code: http://getfuelux.com/javascript.html#tree-usage-javascript).
The first argument to the dataSource is the "parent data" when you click on a tree node (with the second argument being the callback that you send the new array of child data).
This way you can use the selected event for getting your ID, because it gets the jQuery data passed to it.

How to create an instance with the new constructor for every node in a json?

I am about to start writing an App which is an Organizational Chart and I will be using this library where the code example they provide is very clear:
var options = new primitives.orgdiagram.Config();
var items = [
new primitives.orgdiagram.ItemConfig({
id: 0,
parent: null,
title: "Scott Aasrud",
description: "VP, Public Sector",
image: "demo/images/photos/a.png"
}),
new primitives.orgdiagram.ItemConfig({
id: 1,
parent: 0,
title: "Ted Lucas",
description: "VP, Human Resources",
image: "demo/images/photos/b.png"
}),
new primitives.orgdiagram.ItemConfig({
id: 2,
parent: 0,
title: "Joao Stuger",
description: "Business Solutions, US",
image: "demo/images/photos/c.png"
})
];
options.items = items;
options.cursorItem = 0;
options.hasSelectorCheckbox = primitives.common.Enabled.True;
jQuery("#basicdiagram").orgDiagram(options);
which is weird for me, is the items array, I will not be placing that array in the main file where I am going to be constructing my App. Actually the data will come from a json, so just imagine that items array coming from a separate json file, so . . . what should I do in order to put that data in a json, and then call it in my main file, and create the instances like this new primitives.orgdiagram.ItemConfig({ . . . }) for every node in that json?
What are your suggestions?

You can use [].map. It creates a new array with the values returned by a function called with each array item as an argument:
var items = JSON.parse(myjson).map(function(item) {
return new primitives.orgdiagram.ItemConfig(item);
});

Actually, that definition of nodes via new object is done for the sake of code readability, in order to reference user to options of proper object type. Chart supports JSON objects as well.
var options = new primitives.orgdiagram.Config();
var items = [
{
id: 0,
parent: null,
title: "Scott Aasrud",
description: "VP, Public Sector",
image: "demo/images/photos/a.png"
},
{
id: 1,
parent: 0,
title: "Ted Lucas",
description: "VP, Human Resources",
image: "demo/images/photos/b.png"
},
{
id: 2,
parent: 0,
title: "Joao Stuger",
description: "Business Solutions, US",
image: "demo/images/photos/c.png"
}
];
options.items = items;
options.cursorItem = 0;
options.hasSelectorCheckbox = primitives.common.Enabled.True;
jQuery("#basicdiagram").orgDiagram(options);

items not within the <ul></ul>

I create a menu with a javascript object and jquery. I have certain items that needs to be in the <ul></ul> but instead they're beneath it.
http://jsfiddle.net/MWBt6/
I have 'Index' for example. In there I want to append a list of items.
I know the category id is 0 and the item id is 2, i stored those things in the data attribute.
Now how can I append a ul to that one?

That's not how append works. You need to create the elements on their own. Here:
var loadPath = "resources/books/book1/";
var menu = {
data: [{
name: "the book",
id: 0,
items: [{
name: "Introduction",
id: 0,
target: "inleiding.html"
}, {
name: "Content",
id: 1
}, {
name: "Index",
id: 2
}]
}, {
name: "my stuff",
id: 1,
items: [{
name: "Notes",
id: 0
}, {
name: "Marks",
id: 1
}]
}, {
name: "other",
id: 2,
items: [{
name: "Search",
id: 0
}, {
name: "Continue Reading",
id: 1
}]
}]
}
$(document).ready(function() {
var $menu = $('#menu');
for(var i = 0; i < menu.data.length; i++) {
var categorie = menu.data[i];
var categorieName = categorie.name;
var categorieId = categorie.id;
var items = categorie.items;
console.log("categorieName: " + categorieName);
var list = $('<ul>');
for(var j = 0; j < items.length; j++) {
var itemId = items[j].id;
list.append($('<li>').attr('data-itemId', itemId).text(items[j].name));
}
$menu.append(
$('<li>').attr('data-categorieId', categorieId).append(categorieName, list)
);
}
});​
Here's the updated jsFiddle.

You are trying to append as if the DOM is a text editor. You can't append the beginning of an element with it's opening tag, then later close that element with an append of a closing tag. Only full valid elements can be inserted into the DOM.
Instead, build an html string, then only make one append after the string is completed. This method is far more efficient than doing multiple appends also
