I use an angular 2 multiselect. When user clicks it an API gets called in the background and displays options in the drop-down. But as the API is taking time to give response the dropdown is showing as "No data available" and then showing the response when it recieves. How to change that default text to something like "Loading..." ?
Replace "No data available" with "Loading..." as default text. When the API is called and fetches response as you might be overriding dropdown options with response that will replace "Loading...". And If API fetches 0 response then you should replace with "No data available".
If you show "No data available" before just calling API then that means you are saying user that dropdown does not have any value but it brings value later. By this you are conveying wrong idea about the drop-down which is not aligned with UX what you need, If you agree.
Below solution is a hack, may be you want to rewrite as per requirement because I am assuming your code looks somewhat as below but I used along with solution:
html:
<ng-multiselect-dropdown
[placeholder]="text"
[data]="dropdownList"
[(ngModel)]="selectedItems"
[settings]="dropdownSettings"
(onSelect)="onItemSelect($event)"
>
</ng-multiselect-dropdown>
ts:
//Declare settings
this.dropdownSettings = {
singleSelection: false,
idField: 'id',
textField: 'text',
selectAllText: 'Select All',
unSelectAllText: 'UnSelect All',
noDataAvailablePlaceholderText: "Loading...",
itemsShowLimit: 3,
allowSearchFilter: true,
limitSelection: 2
};
}
onClick(){
// then api call here will replace the string most probably
}
There was a drop-down setting property called "noDataLabel"
which did the trick.. it's value is used when no data is available.

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
});
I want create labels via google script(executed in my drive folder). This new labels must be not flaged as "show in IMAP".
I don't found how do this in the API documentation.
Acttualy I'm using "GmailApp.createLabel(label)".
But don't have parameters or methods for change this flag
Any idea how to do it?
Thanks.
-- EDITED for more info --
Following the documentation of this urls:
1)https://developers.google.com/apps-script/reference/gmail/gmail-app#createLabel(String)
2)https://developers.google.com/gmail/api/v1/reference/users/labels/create
Using any of this cases i can create new tags without problems, but none of the two apis, allows us to set the flag "show in IMAP" to false.
This flag is visible via gmail->Configuration->labels. Is a checkbox in the options of each label.
I Want change this flag using google script but i don't found how can i do this.
example used for the apps-script documentation:
var label = "Example Label";
var gmailLabel = GmailApp.getUserLabelByName(label) ?
GmailApp.getUserLabelByName(label) : GmailApp.createLabel(label);
example used for api v1/reference/users/labels/create
-- -------
var request = gapi.client.gmail.users.labels.create({
'userId': userId,
'label': {
'name': "Example Label"
}
});
In the first case, we only can set the label name, in the second case we can define more parameters.
(labelListVisibility,messageListVisibility,name, color.backgroundColor , color.textColor).
None of they are for disable "show in IMAP".
I have an array of divs which can be selected (change background colour on click to signify that to the user).
I want a way to submit the ids of all of these divs to my app, though can't see a 'nice' way of doing this; at the moment the only thing I can see to do is have a button that onclick triggers a javascript function that gets the id's and sends them back to my server in a POST.
Is there a way of creating a multiple select input on a form which uses divs instead of checkboxes or a multi-select list, or a better way of doing what I'm attempting?
Assuming you add the class selected when a user 'selects' the div:
var data = {};
$(".classOfDivs.selected").each(function(){
data[$(this).prop('id')] = 'true';
}
$.ajax({
url : 'ajaxPage.php',
type : 'POST',
dataType : 'text',
cache: false,
data: data,
success : function(text){alert('Saved: '+text);},
error: function(){alert('Did not reach server');}
});
Use the success function to process the returned text as needed. dataType can be changed to html, JSON, etc. See the .ajax() documentation.
Have a hidden input for each div, all with the same name but with a different id. When a div is clicked update the corresponding hidden input with the id. Then when you submit through a standard form POST all of those values will be available through the name you specified.
Since this is an app, what you could do is store everything in HTML5 localstorage using the JQuery javascript library.
Here's how to do it step by step:
Create a jquery array
on click, get div id and store it in the array with a key/value pair
if clicked again, remove it from the array
have some event listener like a "submit" button to store the value of your array to localstorage
Here is a jsfiddle I had that has exactly what you are talking about: http://jsfiddle.net/CR47/bqfXN/1/
It goes into a little more depth but the jquery should be exactly what you need.
The reason this is better than submitting with POST or using ajax is because since you say this is an app, you will be able to use this method offline, where as post or ajax would require a connection to a server running php.
var skinCare=[]; //the array
$('.skinCare').click(function(){ //onclick
var value = event.target.className.split(" ")[0]; //get classname, you would get id
var index = skinCare.indexOf(value); //gets where the location in
//the array this code is
if($(this).hasClass('selected')){ //when a div is clicked it gets
//$('.skinCare').removeClass('selected'); //the class "selected" and adds
skinCare.splice(index, 1); //to array, then another click
} else if($.inArray(value, skinCare) == -1){ //removes it from array
skinCare.push(value);
}
});
$('.submitbutton').click(function(){
localStorage.setItem('Skin Care', JSON.stringify(skinCare));
});
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
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;
});
