I am new to ext js (working on ext js 6.2) and trying to get values from combo box to get 3d bar chart from selected value, but neither I am getting selected value nor the chart with selected value. Please help me getting out of this problem.
my codes are as under :

var chart = this.lookupReference('chart');

You should attach a select listener to your combobox:
{
xtype: 'combobox',
hideLabel: true,
store: {
type: '2fa-data'
},
valueField: 'zone',
displayField: 'zone',
typeAhead: true,
queryMode: 'local',
triggerAction: 'query',
emptyText: 'Select a Zone...',
selectOnFocus: true,
width: 200,
indent: true,
listeners: {
select: 'onItemSelected' //this one
}
}
Notice in your onItemSelected method in your ViewController:
onItemSelected: function (sender, record) { //<- param is sender
//var zone = combo.getValue(); //you are using combo, this is undefined
var zone = sender.getValue();
// or better yet, why not use the `record` parameter?
var theValue = record[0].data.zone;
},
The binding feature of Sencha Ext JS MVVM architecture helps to write declarative code and avoid writing handlers in controllers. Since it's a migration to 6.2, this approach can be taken to remove unnecessary handlers in the controller. Here's a small example on this.
Update:
With reference to the provided example, please read the following points:
The parent class Panel has a View Model, which is available down the hierarchy to combo box and chart components.
View Model has a data property rec, which holds reference to the selected record from combo box. The selection property of combo box is bound to this rec property. It means that the moment a new record is selected from combo box, the rec property of View Model gets updated.
The View Model also has two stores - comboStore and chartStore
a. comboStore: - contains complete data set. It is bound to the combobox.
b. chartStore:- is the child store of comboStore (a child store takes its data from the parent store but has additional capability of filtering and sorting, independent of the parent store.). It is bound to the chart component and filters on the rec.name property (i.e the moment rec is updated, filtering is triggered.) So, technically, this store always contains only the selected record from combo box. And since chart is bound to this store, it gets updated too and shows the selected record's 3dbar graph.
Here's the inline code. Please see the comments for more.
Ext.define('MyPanel', {
extend: 'Ext.panel.Panel',
layout: 'vbox',
//Declare parent class view model
//This view model will be available down the hierarchy
viewModel: {
//Declare viewmodel's static data properties
data: {
//This references the selected record from combo box
rec: null,
},
//Declare stores for this viewmodel
stores: {
//Declare store for combo box containing complete dataset
comboStore: {
fields: ['name', 'apples', 'oranges'],
data: [{
name: 'Eric',
apples: 10,
oranges: 13
}, {
name: 'Mary',
apples: 7,
oranges: 20
}, {
name: 'John',
apples: 5,
oranges: 12
}, {
name: 'Bob',
apples: 2,
oranges: 30
}, {
name: 'Joe',
apples: 19,
oranges: 17
}, {
name: 'Macy',
apples: 13,
oranges: 4
}]
},
//Declare store for chart component
chartStore: {
//This is child store of 'ComboStore'. Its data source is 'comboStore'
source: '{comboStore}',
//This filters this child store to contain only the selected record from combo box
filters: [{
//This filters the store by 'name' property, which is the 'displayField' of combo box
property: 'name',
//This binding helps to filter by the selected record's 'name' property
//'rec' is the selecte record which is available in the view model
value: '{rec.name}'
}],
}
}
},
items: [{
xtype: 'mycombo',
bind: {
//This binding provides 'comboStore' data to the combobox
store: '{comboStore}',
//The selection property of combo box is published to the viewmodel
//and its reference is stored in the viewmodel data property 'rec'
selection: '{rec}'
}
}, {
xtype: 'mychart',
bind: {
//This binding provides 'chartStore' data to the chart component
//Since it is bound, the moment this store is updated/filtered, the chart view gets updated too
store: '{chartStore}'
}
}]
});
Please change listeners for select event instead of panel to combobox. Panel don't have select event.
I have created an Sencha Fiddle demo for combobox select/change both event. it will show how it is working. Hope this will help you to solve you problem or achieve your functionality.
// The data store containing the list of states
var states = Ext.create('Ext.data.Store', {
fields: ['abbr', 'name'],
data: [{
"abbr": "AL",
"name": "Alabama"
}, {
"abbr": "AK",
"name": "Alaska"
}, {
"abbr": "AZ",
"name": "Arizona"
}]
});
// Create the combo box, attached to the states data store
Ext.create('Ext.form.ComboBox', {
fieldLabel: 'Choose State',
store: states,
queryMode: 'local',
margin: 10,
displayField: 'name',
valueField: 'abbr',
renderTo: Ext.getBody(),
listeners: {
select: function (combo, record) {
Ext.Msg.alert('Success', 'Congrtas you have selected <b>' + record.get("name") + '</b>');
}
/*change: function (combo, newValue,oldValue) {
Ext.Msg.alert('Success', 'Congrtas you have selected <b>' + newValue + '</b>');
}*/
}
});
I am using ExtJs to create a combobox.
Here is my code:
Ext.define('Form.FormTypeDialog', {
extend : 'Ext.Window',
id: 'formTypeDialog',
formId: null,
callbackFunction : null,
modal: true,
statics : {
show : function(formId, callback) {
Ext.create(Form.FormTypeDialog", {
formId : formId,
callbackFunction : callback
}).show();
}
},
constructor : function(config) {
var me = this;
Ext.apply(this, {
buttons : [
{
text:"#{msgs.form_create_dialog_button_cancel}",
cls : 'secondaryBtn',
handler: function() {
me.close();
}
},
{
text:"#{msgs.form_create_dialog_button_next}",
handler: function() {
// Get selected form type
}
}
]
});
this.callParent(arguments);
},
initComponent:function() {
this.setTitle("#{msgs.form_create_dialog_title}");
this.setHeight(175);
this.setWidth(327);
var formTypeStore = Mystore.Store.createRestStore({
url : getRelativeUrl('/rest/form/formTypes'),
root: 'objects',
fields: ['name','value']
});
this.form = new Ext.form.Panel({
style:'padding:15px;background-color:#fff' ,
border:false,
bodyBorder:false,
items:[
new Ext.form.Label({
text: "#{msgs.form_create_dialog_select_type_label}",
margin: "25 10 25 5"
}),
new Ext.form.ComboBox({
id: 'createformTypeCombo',
margin: "8 10 25 5",
allowBlank: false,
forceSelection: true,
editable:false,
store: formTypeStore,
valueField: 'value',
displayField: 'name',

I am creating this window on a xhtml page on a button click using :
Form.FormTypeDialog.show(null, showFormWindowCallBack);
It works fine and combo box is displayed and I can select value.
But if I open and close it 4 times, then in next show it shows the values but It do not allow me to select the last two value. I can only select first value.
Please suggest.
Note: I have tried copying and executing this code in forms of other pages of my application. But behavior is same in all cases.
This combobox is on a Ext.Window.
EDIT:
JSON RESPONSE FROM Rest:

I have re-created this code, I had some errors showing in Firefox using your code directly so I've changed some things.
Running the code below and calling Ext.create("Form.FormTypeDialog", {}).show(); in the console window, then closing the window and repeating does not replicate this issue. Could you try using the code I have and see if you still have the same problem.
Ext.application({

'value'
],
data: myData,
storeId: "myStore"
});
this.form = Ext.create("Ext.form.Panel", {
style: 'padding:15px;background-color:#fff',
border: false,
bodyBorder: false,
items: [
Ext.create("Ext.form.Label", {

margin: "25 10 25 5"
}),
Ext.create("Ext.form.ComboBox", {

margin: "8 10 25 5",
allowBlank: false,
forceSelection: true,
editable: false,
store: formTypeStore,
valueField: 'value',
displayField: 'name',
width: 260,
emptyText: '#{msgs.form_create_dialog_select_type}'
})
]
});
this.items = [
this.form

this.callParent(arguments);
}
});
Ext.create('Ext.Button', {
text: 'Click me',
renderTo: Ext.getBody(),

Ext.create("Form.FormTypeDialog", {}).show();

}
});
You can also play around with this code using / forking from this Fiddle
It is not clear what your problem is.
I use remote combo follows:
Ext.define('ComboRemote', {
extend: 'Ext.form.ComboBox',
xtype: 'ComboRemote',
emptyText: 'empty',
width: 75,
displayField: 'name',
valueField: 'id',
store: {
model: 'ComboModel',
proxy: {
type: 'rest',
url: '/serv/Res',
extraParams: {
query: ''
},
reader: {
root: "result", type: 'json'
}
},
autoLoad: true,
},
queryMode: 'remote',
pageSize: false,
lastQuery: '',
minChars: 0});
Ext.define('ComboModel', {
extend: 'Ext.data.Model',
fields: [
'id',
'name'
]});
I hope to help
Try these possible solutions
1. Make AutoLoad property for store as true.
2. Add delay of some ms
Here is a demo to for the behavior I am experiencing.
If you edit the existing row with id 1, change the text to something else and then press the cancel button, the row is reverted correctly to its previous state.
In order to reproduce my problem you need to:
Add a new row
Press the update button to save it.
Select the row again and press the update button.
Press the cancel button
The row disappears!
Even though there are similar questions on this problem, I have yet to find a satisfactory answer.
Some people say that I need to define an id. As you can see from my demo, this does not make any difference, the new row has an id and it still disappears.
There are some suggestions when you are using a remote datasource, but this does not work in my case, I need to use local data.
Finally, there is this answer. While it does prevent the new row from disappearing, Canceling the row does not revert the data to its old state, it only closes the editor and the data are as they where after the edit.
Had the same problem. I had it solved by simply calling the cancelChanges() method of the DataSource:
..
cancel: function(e) {
$('#mainGrid').data('kendoGrid').dataSource.cancelChanges();
},
..
It seems like bug only.But still you could acheive desired output through the below code.
I have introduced new variable tempSavedRecords and update
that variable when you are save or delete the record with kendo
datasource data.
When the user clicks cancel button fill the kendo datasource with tempSavedRecords.
$(document).ready(function() {
var tempSavedRecords = null;
var gridDataSource = new kendo.data.DataSource({
data: [
{ id: 1, description: 'Test 1', begin: new Date() }
],
schema: {
model: {
id: 'id',
fields: {
id: { type: 'number' },
description: { type: 'string' },
begin: { type: 'date' }
}
}
}
});
$('#grid').kendoGrid({
dataSource: gridDataSource,
scrollable: true,
sortable: true,
toolbar: ['create'],
columns: [
{ field: 'id', title: 'ID', width: 'auto' },
{ field: 'description', title: 'Description', width: 'auto' },
{ field: 'begin', title: 'Begin', width: 'auto', format: '{0:d}' },
{ command: ['edit', 'destroy'], title: ' ', width: '172px'}],
editable: {
mode: 'inline',
confirmation: false
},
save:function(e){
updateTempRecords();
},
cancel:function(e){
if(tempSavedRecords != null){
$('#grid').data('kendoGrid').dataSource.data(tempSavedRecords);
}
else{
$('#grid').data('kendoGrid').dataSource.cancelChanges();
}
},
remove:function(e){
$('#grid').data('kendoGrid').dataSource.remove(e.model)
updateTempRecords();
}
});
function updateTempRecords(){
tempSavedRecords = $('#grid').data('kendoGrid').dataSource.data();
tempSavedRecords = tempSavedRecords.toJSON();
}
});
Hope this helps.Thanks.

This happens because the id remains set to its default value. The data source considers such data items as "new" and cancelling them removes them. Once you save a "new" item you need to set its id to a non-default value.
I modified your changes with this pluckr, and it seems to work.
The only change that I did was to rename 'id' column to 'ided'.
Somehow the 'id' column name, as shown in kendo examples does not work, and to me it seems like a bug.
model: {
id: 'ided',
fields: {
ided: { type: 'number' },
description: { type: 'string' },
begin: { type: 'date' }
}
}
I could resolve this problem by re-setting the data object after add new row.
For example:
function onInsertNewRow(dataItem) {
myDataSource.insert(dataItem);
myDataSource.data(myDataSource.data());
}
By calling data() method you say to grid that the new data asigned is the base data and the new rows are no longer new.
I hope this help you.

#
It's giving the numbers in alert dialogue of the selected rows,here
alert(selModel.getCount());
But after this it's throwing a javascript error "selModel.getView is not a function" in the line bellow
var selected = selModel.getView().getSelectionModel().getSelections();
I changed it to var selected = grid.getView().getSelectionModel().getSelections(); Still it's throwing same kind of error(grid.getView is not a function).
Try this
var selected = selModel.getSelection();
Instead of this
var selected = selModel.getSelectionModel().getSelections();
You already have the selection model, why are you trying to ask to get the view to go back to the selection model? It's like doing node.parentNode.childNodes[0].innerHTML.
selModel.getSelection(); is sufficient. Also be sure to read the docs, there's no getView method listed there for Ext.selection.CheckboxModel, so you just made that up!

If you try and render a component to a dom element that isn't found (or dom ID that isn't found) you'll get that error. See the example below to reproduce the error - then comment out the bad renderTo and uncomment the renderTo: Ext.getBody() to resolve the issue.

It means that the object which you expect to have the dom attribute is undefined.
EDIT:
The error generates at this line:
formPanel.body.dom
It means that the formPanel is not rendered because you are trying to access its body property. This property is Available since: Ext 4.1.3
I'm seeing a similar error in code that executes for validation. What I'm doing has nothing to do with directly accessing the DOM, however I'm still getting a similar condition. The answer above is incomplete, the dom property is available on some ui elements in 3.x...
in earlier versions of Extjs (3.x) the property is mainBody.dom and not body.dom
directly from the source of hasRows() for grids in 3.4:
var fc = this.**mainBody.dom**.firstChild;
return fc && fc.nodeType == 1 && fc.className != 'x-grid-empty';
