I'm struggeling with DOJO 1.8 and Datagrid. I would like to put a filteringSelect into a Datagrid cell. The widget should be fed by a Store. The store is fed by an AJAX request and works find. Also the select widget shows up, but it is empty. There's neither a value nor an option to see in the browser:
The Code for the Store:
// AJAX REQUEST TO GET PROJECTS AND SAVE AS STORE
require(['dojo/request', 'dojo/data/ItemFileReadStore'], function(request, ItemFileReadStore){
request('project/json/getprojects', {
handleAs: 'json'
}).then(function(json){
var projectStore = new ItemFileReadStore({data: {'identifier':'id', 'label':'label', 'items': json}});
});
The JSON I retrieve looks like this:
[{"id":2,"name":"Bilder-App","customer":"Company A","label":"Company A >> Bilder-App"},{"id":8,"name":"Zeiterfassung","customer":"Company B","label":"Company B >> Zeiterfassung"}]
The goal is that the select-box shows the "label" field visually and saves "id" to the store/grid.
Here's the code of the grid_layout for the cell:
{field: "project_id", name: "Kunde/Projekt", type: dojox.grid.cells._Widget, widgetClass: dijit.form.Select, widgetProps: {store: projectStore, searchAttr: "label"} },
Is anyone able to help me with that?
MANY THANKS!

Here is the working formatter:
// PROJECT-ID FORMATTER
function formatProjectId(value, index){
var item = projectStore.get(value);
var label = item['label'];
return label;
}
However, there's one slight problem: Right when I selected the item in the select box it shows the id in the field. When I leave the field it gets formatted correctly.
Does anyone know how to solve this?
OK!
I was able to find a solution.
First of all, I changed to Memory-Store, since I figured out that the ItemFileReadStore wasn't working correctly.
I read somewhere, that you need to require the 'dijit/form/FilteringSelect' specifically. So I did that.
So my field in the layout variable looks like this:
{field: "project_id", name: "Kunde/Projekt", type: dojox.grid.cells._Widget, widgetClass: dijit.form.FilteringSelect, widgetProps: {searchAttr: "id", labelAttr: "label", store: projectStore}},
My Store has an array of data consisting of the fields 'id' and 'label'...so it gave the field those attributes! And BOOOOM...it works!
Now I have to add a formatter-function to format the displayed IDs onces they were edited.
Posting about this soon!
Have a good one,
AFX

I'm developing a stock manager webapp for a company.
I have this page where the administrator can edit and delete products that they added in a table (dataTable), I managed to make this possible by using this tutorial:
https://www.webslesson.info/2017/05/live-table-data-edit-delete-using-tabledit-plugin-in-php.html
Everything works fine but I had this issue where the 2 edit and delete buttons weren't showed on other pages of my table except from the 1st, I managed to resolve this issue with attached code
Everything right now works fine but i have a huge graphic problem. While i'm searching, every time I tap a letter or a backspace, the last column as you can see from the attachment is cloning itself every time.
Error of multiple columns
I've already tried to debug the search method but I don't think it's related to that... it's a standard method.
Do you think it can possibly be a problem related to the fact that the last column with the 2 button (edit and delete) is automatically added with a js of the library extension I'm using and it's not hardcoded? so every time I redraw the table it is like an external element to redraw?
var table = $('#dataTable').DataTable();
// Document ready
$(function() {
editTable();
});
// Assuming "table" is the variable name of your datatable
table.on('draw', editTable);
function editTable() {
$('#dataTable').Tabledit({
url: 'updateDB.php',
columns: {
identifier: [0, "id"],
editable: [
[1, 'name'],
[4, 'quantity'],
[5, 'threshold'],
]
},
restoreButton: false,
onSuccess: function(data, textStatus, jqXHR) {
if (data.action == "delete") {
document.getElementById(data.id).remove();
}
}
});
};
I am trying to get Kendo Grid data which is hydrated from client side to a MVC controller method. My view contains several single fields like name, date of birth etc and tabular field which I hooked with a Kendo Grid. Since its a new operation I have no data in the grid ( and other fields) and user enters them from client side.
I have no idea how to proceed on this. Ideally I would like to get this data to a list in my viewmodal. So that when the user hits save, I have all other data and the grid data coming into a controller method.
I am able to successfully bind a list with kendo grid and display it. I have very little experience on JavaScript and Kendo and web programming.
If any of you can point me to the right direction, sample code would be greatly appreciated.
$("#departmet").kendoGrid({
dataSource: dataSource,
height: 250,
scrollable: true,
sortable: true,
filterable: true,
pageable: {
input: true,
numeric: false
},
columns: [
"DepartmentName",
"SubDivision"
]
});
From experience I know their documentation is not easy to navigate. It seems there is the documentation and then the API. The API is usually what you will always want to find. What you will need is the information from here https://docs.telerik.com/kendo-ui/api/javascript/ui/grid. If I understand the question correctly. There are several ways you can achieve posting. You could make use of editor templates. Click the Open in Dojo to get an idea how it looks.
https://docs.telerik.com/kendo-ui/api/javascript/ui/grid/configuration/editable.template
With this you do not have to worry about modifying the data via javascript. Assuming your grid is surrounded with a form element it will get posted when submitted. Note paging is not accounted for here. Also, this method by default can auto post after each edit. If you don't want this behavior then you will have to have advanced knowledge of the API.....Correction on that last statement. The API is different when dealing with the data all on the client side. Click the Open in Dojo to see it all on the client side. If you are not wanting to use editor templates and want to manage the data editing yourself then you need to use the grid methods provided.
Once you have your grid created. To access the data source of the grid you will need to get the dataSource.
$('#departmet').data('kendoGrid').dataSource;
https://docs.telerik.com/kendo-ui/api/javascript/data/datasource
If you need to use a different data source(or change it) you can use the setDataSource method below(grid function).
https://docs.telerik.com/kendo-ui/api/javascript/ui/grid/methods/setdatasource
To add to the data source use the add function to add a new object.
$('#departmet').data('kendoGrid').dataSource.add({ id: 2, name: 'name'});
https://docs.telerik.com/kendo-ui/api/javascript/data/datasource/methods/add
It is important with kendo to ALWAYS use the methods provided to change the data source so that the proper events can fire to update the UI accordingly. This includes if you need to set a property on a specific data item. In that case you need to use the set method on the item itself.
After you are done modifying your data. Within javascript get the data and either create DOM elements within a form
//JQuery sudo code example
var data = $("#departmet").data("kendoGrid").dataSource.data();
var dataLen = data.length;
var myForm = $('#my-form'); //Already within DOM
for (var i = 0; i < dataLen; i++) {
var item = data[i];
var idEl = $('<input type="hidden" name="userData[' + i + '].id" />');
idEl.val(item.id);
var nameEl = $('<input type="hidden" name="userData[' + i + '].name" />');
nameEl.val(item.name);
myForm.append(idEl);
myForm.append(nameEl);
}
myForm.submit();
This assumes your controller function(??) on the backend is expecting an array of objects with the property name of userData.
Alternatively, you can post it via ajax. For example, the ajax jquery function. Passing your data as the data of the ajax call.
http://api.jquery.com/jquery.ajax/
Don't want to ramble. Let me know if you need more help.
SO won't let me comment yet so have to add another answer. You will not need to define the data source within the .NET code when dealing with client only data. Just use this.
.DataSource(dataSource => dataSource
.Ajax()
.ServerOperation(false)
)
If you will have data coming from the backend then you need to use the generic-less constructor and pass in the object else keep what you have.
Html.Kendo().Grid(Model.MyList)
However, if you are preprocessing some client data on the screen that you want to initialize then you will need to do this on ready. Don't worry about the schema part of the data source. It already knows this when you used the .NET MVC wrapper because you gave it the schema(type) via the generic or the parameter provided.
var initialDS= new kendo.data.DataSource({
data: [
{ ActionName: "Some Name", ActionType: "Some Type" }
]
});
$(document).ready(function () {
$('#docworkflow').data('kendoGrid').setDataSource(initialDS);
});
As I mentioned in the other answer. Use the data source functions for adding additional data to the data source. No need to setDataSource each time you want to add. Just
//Assuming you have 2 inputs on the screen the user is entering info into
var nameEntry = $('#action-name').val();
var typeEntry = $('#action-type').val();
$('#docworkflow').data('kendoGrid').dataSource.add({ ActionName: nameEntry , ActionType: typeEntry });
So after some efforts I come up with. But I don't know where to specify the
data in the html code. Is it possible this way?
#(Html.Kendo().Grid <DockData.Action> ()
.Name("docworkflow")
.Columns(columns =>
{
columns.Bound(e => e.ActionName);
columns.Bound(e => e.ActionType);
}).DataSource( **How do I load a script variable here***)
//This script variable should be fed to the above code.
This variable is populatedwhen the user adds data from the UI which works fine.
var dataSource = new kendo.data.DataSource({
data: result,
schema: {
model: {
fields: {
ActionName: { type: "string" },
ActionType: { type: "string" }
}
}
},
pageSize: 20
});
Is this possible.. here's what I have atm, but my data object is just returning a load of jargon, what am I doing wrong? Am I doing anything.. right, for that matter?
I basically want to print out a list of a users videos (thumbnail and title, and make each one a clickable link to the video itself)
Thanks!
$(document).ready(function(){
$player.init();
})
var $player = (function(){
var player = {};
player.init = function(){
//init Youtube knockout
player.initYoutubeKnockout();
}
player.knockoutModel = {
videoData : ko.observableArray([]),
}
player.initYoutubeKnockout = function()
{
//load the Youtube json feed
$.ajax({
url: 'http://gdata.youtube.com/feeds/api/users/USERNAME/uploads?v=2&alt=json',
type: 'GET',
dataType: 'jsonp',
data: {
count: 5
},
success: function(data, textStatus, xhr) {
player.doYoutubeKnockout(data.item);
}
});
}
player.doYoutubeKnockout = function( data )
{
player.knockoutModel.videoData(data);
ko.applyBindings(player.knockoutModel, $('#youtube-feed')[0]);
console.log($(this));
}
return player;
})();
Frankly you weren't doing much at all.
The JSON data you get back from YouTube is not from data.item, it's in a completely different structure.
I'm assuming you wish to get 5 uploads from the user. The parameter name would be max-results, not count.
Probably the only thing you did fine was set up the url but that's about it.
You need to examine how the JSON returned looks like. Check the API reference for the structure of an atom feed. This is in XML but the corresponding JSON responses will have pretty much the same format with some minor differences. Examine the object by writing it to the console to verify you're getting the right properties.
Once you understand that, you need to use the correct query to get what you're expecting. Check out their API reference on their query parameters.
To help simplify your knockout code, I would strongly recommend you take the response you get back and map it to an object with simplified property names. For instance, to get the thumbnails for an entry, you would have to access the media$group.media$thumbnail array. It would be easier if you can just access it through thumbnail.
Also, if your elements you are binding to need to bind multiple values, it would help to map the values in such a way that your bindings are made easier. For instance, when using the attr binding, you'd set up a property for each of the attributes you want to add. Instead you could just group all the properties in an object and bind to that.
I wrote up a fiddle applying all that I said above to do as you had asked for. This should help give you an idea of what you can do and how to do it.
Demo
I am having a horrible time understanding Sencha Touch 2's architecture. I'm finding even the most basic things I do in other language and frameworks to be incredibly painful.
Currently, I just want to do a standard Master/Detail view. I load a store into a list view and would like to click on each list item to slide in a detail view. Since my initial list view can contain quite a lot of items, I'm only loading a little bit of the data with this method in my controller:
viewUserCommand: function(list, record) {
// console.log(record);
var profileStore = Ext.getStore("Profiles");
profileStore.setProxy({
url: 'http://localhost:8000/profile/' + record.data.user_id
});
profileStore.load();
// console.log(profileStore);
Ext.Viewport.animateActiveItem(Ext.getCmp('profileview'), this.slideLeftTransition);
}
First, modifying the url property for each tap event seems a bit hacky. Isn't there a way to specify "this.id" or something along those lines, and then pass that to my store? Or would that require loading the entire DB table into an object?
I can console.log the return from this method and it's exactly what I want. How do I populate the detail view? I've tried utilizing a DataView component, but it doesn't show any data. The examples on sencha's website are fairly sparse, and relatively contextless. That means that even copying and pasting their examples are likely to fail. (Any examples I've tried using Ext.modelMgr.getModel() have failed.)
I know it's partly that this framework is new and I'm probably missing a huge gaping hole in my understanding of it, but does anyone have any clue?
Would suggest you check out the docs, there's an example of loading a single model:
http://docs.sencha.com/touch/2-0/#!/api/Ext.data.Model
Ext.define('User', {
extend: 'Ext.data.Model',
config: {
fields: ['id', 'name', 'email'],
proxy: {
type: 'rest',
url : '/users'
}
}
});
//get a reference to the User model class
var User = Ext.ModelManager.getModel('User');
//Uses the configured RestProxy to make a GET request to /users/123
User.load(123, {
success: function(user) {
console.log(user.getId()); //logs 123
}
});
So I currently have a table that's generated by ajax and json file.
The table has 3 segments, a name, an ID and the third column is a link for more details of each result.
Example of how my table looks
PATO:0001243 light blue Details
PATO:0001246 light brown Details
PATO:0001247 light cyan Details
the current code I have to generate the table is:
$.each(data.matches, function(i, item){
var this_row_id = 'result_row_' + next_row_num++;
$('<tr/>', {"id":this_row_id}).appendTo('tbody');
$('<td/>', {"text":item.label}).appendTo('#'+this_row_id);
$('<td/>', {"text":item.value}).appendTo('#'+this_row_id);
$(''+ 'Details' +'').appendTo('#'+this_row_id);
});
Ideally, I would like to be able to click on the "Details" and it would pass the ID value to another ajax call and then create a dialog/modal to display the results of that ajax call.
EXAMPLE
From the list above, clicking on "Details" from the first entry will pass the values "PATO:0001234" to my "test.cgi" script which will use that value to process and spit back out a JSON for me to display in a dialog.
I'm not asking for someone to write my code for me, just some direction about how to approach this.
I think I'm probably wrong to link directly to my cgi script from the <a href>. But I don't know how to link that to an ajax call from a text link.
Update
Left the page loaded too long; #floatless has posted a cleaner approach with chaining, didn't think of that.
You could change the last few lines to something like what's below. The idea is to attach a handler to each link when it's created which will call the loadDetail function with the appropriate item label. In loadDetail, it's then a simple matter of making an ajax request with the label as the parameter.
Note that you don't need to use ./test.cgi - test.cgi will suffice.
...
$(''+ 'Details' +'').appendTo('#'+this_row_id);
$('#detail_' + this_row_id).click(loadDetail(item.label));
}
function loadDetail(label){
$.get('test.cgi', {label: label}, function(data){
//create your dialog to display the response data
});
}
You could append click event handler while generating table:
$(''+ 'Details' +'').appendTo('#'+this_row_id).click(function()
{
$.getJSON("./test.cgi", {label: item.label}, function(data)
{
//Do something with received data
});
return false;
});
