Ext js form validator validate with unique names

I have Ext Form :
Ext.define('Count.view.AddJListForm', {
extend : 'Ext.form.Panel',
controller : 'List',
xtype : 'add-list',
name : 'addListForm',
cls : 'addFormToolbar',
width : '100%',
height : '100%',
layout : 'hbox',
fullscreen : true,
scrollable : true,
items :
[
{
xtype : 'titlebar',
title : 'Add New Name',
docked : 'top',
},
{
xtype : 'formpanel',
fullscreen : true,
items :
[
{
xtype : 'hiddenfield',
name : 'id'
},
{
xtype : 'textfield',
name : 'ListName',
maxLength : 100,
label : 'List name',
labelAlign : 'top',
required : true
},
{
xtype : 'numberfield',
name : 'Count',
maxLength : 10,
label : 'Count',
labelAlign : 'top',
required : true
},
]
},
{
xtype : 'toolbar',
ui : 'plain',
docked : 'bottom',
items :
[
{
xtype : 'spacer'
},
{
xtype : 'button',
text : 'CANCEL',
name : 'closeAddListFormView',
},
{
xtype : 'button',
text : 'SAVE',
name : 'formSave',
}
]
}
]
});
Controller function :
In this function to get the form values and stored into Database:
Ext.define('Count.view.ListController', {
extend: 'Ext.app.ViewController',
alias: 'controller.JapaList',
control: {
'button[name=formSave]': {
tap : 'saveListData'
}
}
// File save function
saveListData : function(button, record)
{
var form = button.up('formpanel');
var values = form.getValues();
var BgImage = '';
var audioFile = '';
if(form.validate())
{
var ListName = values.ListName;
var Count = values.Count;
callBackSaveData var table = JapaCount.Db.tblJapaList;
toDbArray['ListName'] = ListName;
toDbArray['Count'] = Count;
Count.Db.dbInsertWithCallback(table,toDbArray, me.loadStore, me);
}
data stored on DB. But I need to validate ListName must be unique like a username. if there are any rerecords like the same name it should show an error. In this function were to check that validator or function? anyone have an idea please share

You can find record with ListName using method findRecord on instance of store.
let record = store.findRecord('ListName', ListName, 0, false, false, true);
if (!record) {
//do smth here if ListName not found
}

Autoload Panel Listener ExtJs

I have view file in extjs with a listener code, here it is:
initComponent: function() {
Ext.apply(this, {
title : 'Form Order',
iconCls : 'orderIcon',
width : 850,
maxHeight : 600,
x : 200,
y : 50,
resizable : true,
resizeHandles : 's n',
constrainHeader : true,
closable : true,
modal : true,
autoShow : false,
autoScroll : true,
overflow : 'auto',
layout: {
type: 'auto',
align: 'stretch'
},
items: [
this.createPanelMC()
]
});
this.callParent(arguments);
},
createPanelMC: function() {
this.requiredSign = '<span style="color:red;font-weight:bold" data-qtip="Required">*</span>';
var panel = Ext.create('Ext.form.Panel', {
defaultType: 'textfield',
name: 'nodebPanel',
width: '100%',
layout: {
type: 'auto',
align: 'stretch'
},
items: [{
xtype : 'fieldset',
name : 'modlayanan',
title : 'Data Pelanggan',
layout : 'column',
width : '95%',
margin : '10',
items: [{
xtype : 'textfield',
name : 'nomor',
id : 'nomor',
itemId : 'nomor',
fieldLabel : 'PSTN',
emptyText : 'Nomor...',
margin : '10 0 0 0',
width : 350,
labelWidth : 100,
afterLabelTextTpl: this.requiredSign
}, {
xtype : 'textfield',
fieldLabel : 'Speedy',
name : 'speedy',
id : 'speedyVal',
itemId : 'speedyVal',
margin : '10 0 10 20',
width : 350,
labelWidth : 100
}, {
xtype : 'textareafield',
name : 'instaLAddress',
fieldLabel : 'Alamat Instalasi',
emptyText : 'Alamat Instalasi...',
readOnly : true,
labelWidth : 100,
autofocus: true,
//listener
listeners : {
render: function() {
this.getEl().on('mousedown', function(e, t, eOpts) {
var nopstn = Ext.getCmp('nomor').getValue();
var speedy = Ext.getCmp('speedyVal').getValue();
if (nopstn != '' && speedy != '') {
var store = Ext.ComponentQuery.query('#treeProduct')[0].getStore();
console.log(store);
store.load({
params: {
nopstn: nopstn,
speedy: speedy
}
});
}
});
}
}
},
this.createTreePaketExist(),
]
}]
});
return panel;
},
createTreePaketExist: function() {
var storeTree = Ext.create('Ext.data.TreeStore', {
proxy: {
type: 'ajax',
url: 'data/newoss_get_paket.php',
actionMethods :{
create: 'POST', read: 'POST', update: 'POST', destroy: 'POST'
}
}
});
var groupProduct = Ext.create('Ext.tree.Panel', {
store : storeTree,
itemId : 'treeProduct',
renderTo : Ext.getBody(),
name : 'treeProduct',
rootVisible : false,
useArrows : true,
layout :'fit',
margin : '0 0 0 0',
autoScroll : true,
height : 150,
width : '93%',
listeners:
{
checkchange: function(node, checked, eOpts){
node.eachChild(function(n) {
node.cascadeBy(function(n){
n.set('checked', checked);
});
});
p = node.parentNode;
var pChildCheckedCount = 0;
p.suspendEvents();
p.eachChild(function(c) {
if (c.get('checked')) pChildCheckedCount++;
p.set('checked', !!pChildCheckedCount);
});
p.resumeEvents();
}
}
});
return groupProduct;
}
and the listener will show tree panel in createTreePaketExist(). the problem is.. i want show tree panel result without click anything,just show the result when panel is loading.
in my code, the result will show after i put pointer in textareafield. how can it just show without any click, just show when panel loaded? anybody can help me? thanks..

I think this has already been answered in your previous Question.
The issue that you are having here is that your store is dependent on user typed values, so your store can't load until the user has done something.
So you cannot automatically load the store without the values unless you provide default values to load the store with and then it can reload with different data if the user enters new information.
Its difficult to provide an in-depth answer to this without knowing what data the store is working with, how it is filtered based on the user data, what data they can enter or you expect them to enter.

Couldnt read and set Json data with extjs4

I want to read json data in extjs here is my code below.
What i'm doing wrong ? I'm pretty new at Extjs.
I think i couldn't get the json value, or couldn't properly write it down on panel.
Thanks in advance.
Ext.require([ 'Ext.grid.*', 'Ext.data.*', 'Ext.dd.*' ]);
var urlGetName = '${ctx}/main/list';
Ext.define('DataObject', {
extend : 'Ext.data.Model',
fields : [ 'name' ]
});
var storeName = Ext.create('Ext.data.Store',{
model:'DataObject',
autoLoad : false,
proxy : {
type : 'ajax',
actionMethods: {
read: 'GET'
},
reader : {
type : 'json',
root: 'data',
},
api : {
read: urlGetName
}
},listeners: {
load: function(store, records) {
dataa =store.getAt(0).get('data');
}
}
});
Ext.onReady(function() {
var firstGridStore = Ext.create('Ext.data.Store', {
model : 'DataObject',
data : dataa
});
var columns = [ {
text : "Name",
flex : 1,
sortable : true,
dataIndex : 'name'
} ];
// declare the source Grid
var firstGrid = Ext.create('Ext.grid.Panel', {
multiSelect : true,
viewConfig : {
plugins : {
ptype : 'gridviewdragdrop',
dragGroup : 'firstGridDDGroup',
dropGroup : 'secondGridDDGroup'
},
listeners : {
drop : function(node, data, dropRec, dropPosition) {
var urlL = '${ctx}/main/list';
var param = data;
postDataAsParamsINN({param:param},urlL,function(resp){
var success=resp.success;
if(success){
Ext.MessageBox.alert('succes', 'bravaa');
}else{
Ext.MessageBox.alert('error','eroross' );
}
});
}
}
},
store : firstGridStore,
columns : columns,
stripeRows : true,
title : 'First Grid',
margins : '0 2 0 0'
});
});

You shouldn't use two stores to fill the one with the other. Delete the FirstGridStore and use the predefined remote store instead:
// Model
Ext.define('DataObject', {
extend : 'Ext.data.Model',
fields : [ 'name' ],
idProperty: 'name'
});
// Store
var storeName = Ext.create('Ext.data.Store',{
model:'DataObject',
autoLoad: true,
queryMode: local,
proxy: {
type: 'ajax',
actionMethods: {
read: 'GET'
},
reader: {
type : 'json',
root: 'data',
},
api: {
read: urlGetName
}
}
});
// Grid
var columns = [{
text : "Name",
flex : 1,
sortable : true,
dataIndex : 'name'
}];
// declare the source Grid
var firstGrid = Ext.create('Ext.grid.Panel', {
multiSelect : true,
viewConfig : {
plugins : {
ptype : 'gridviewdragdrop',
dragGroup : 'firstGridDDGroup',
dropGroup : 'secondGridDDGroup'
},
listeners : {
drop : function(node, data, dropRec, dropPosition) {
var urlL = '${ctx}/main/list';
var param = data;
postDataAsParamsINN({param:param},urlL,function(resp){
var success=resp.success;
if(success){
Ext.MessageBox.alert('succes', 'bravaa');
}else{
Ext.MessageBox.alert('error','eroross' );
}
});
}
}
},
store : storeName, // defined store
columns : columns,
stripeRows : true,
title : 'First Grid',
margins : '0 2 0 0'
});
});

Controller this.control() method extjs 4

I have a toolbar named DasboardToolbar in which i have a splitbutton.
The problem when I click a menuitem in the splitbutton it fires a event which the controller's this.control method should catch but it doesn't. The object used for firing event is the object of the component still its responding to the fired event.
Any help appreciated.
The is the controller i'm using
Ext.define('MyApp.controller.MainController',
{
extend : 'Ext.app.Controller',
views : [ 'header.MSHeader', 'dashboard.toolbar.DashboardToolbar',
],
init : function() {
console.log("controller");
this.control({
'MSHeader' : {
tabChanged : this.tabChangeTracker
}
}, {
'dash.DashToolbar' : {
layoutSelected :this.layoutSelectedTracker, //errorstatment
}
});
},
layoutSelectedTracker:function(){
console.log('catched'); // code never reaches here
}
});
The Component
Ext.define('MyApp.view.dashboard.toolbar.DashboardToolbar', {
extend : 'Ext.panel.Panel',
alias : 'widget.dash.DashToolbar',
id : 'dashtoolbar',
initComponent : function() {
var me = this;
this.items = [ {
xtype : 'toolbar',
items : [ {
xtype : 'splitbutton',
width : '55',
text : 'layout',
autoScroll : true,
menu : new Ext.menu.Menu({
id : 'layoutmenu',
items : [
{
xtype : 'button',
text : 'First',
handler : function() {
me.fireEvent("layoutSelected", { //eventFired from here
layouts : 1
});
}
}]
})
} ]
} ],
this.callParent();
}
});

Have you tried using the id of the component?
this.control({
'MSHeader': {
tabChanged: this.tabChangeTracker
},
'#dashtoolbar': {
layoutSelected: this.layoutSelectedTracker
}
});
this.control uses Ext.ComponentQuery, have a look at the documentation there.

Change hyperlink text dynamically in Extjs

Below is the code by which I am creating a link in my page using ExtJS:
var linkTransValues = {
xtype: 'box',
id : 'testId',
hidden : true,
autoEl: {
tag: 'a',
href: 'javascript:addCategoryValue()',
html: 'Add Transition Category'
}
}
Now what I want is when user select value from one combo box whatever combo box description is there that description should come in link text here is my code I am calling on select of combo box:
transType.on('select', function(cbox, rec, index) {
Ext.getCmp("testId").transId = cbox.getValue();
Ext.getCmp("testId").autoEl.html="dropdown description";
Ext.getCmp("testId").show();
});
Problem is that it is changing the html value but new value not reflecting its showing the initial value only how to change link value. How can I change that?

Try
var linkTransValues = {
xtype: 'box',
id : 'testId',
hidden : true,
autoEl: {tag: 'a', id: 'my-element', href: 'javascript:addCategoryValue()', html: 'Add Transition Category'}
};
Ext.get('my-element').update('new value');

enter code here
