Itemclick and itemmove in EXTJS MVC - extjs

Am having a tree panel in my view, and its corresponding controllers. What is happening is that am having two controllers, one for the itemdblclick and another for itemmove. The itemdblclick is working ok, but when i add the controller for itemmove, itemmove is working, but on the other hand, itemdbclick is not working. And if i remove the itemmove controller, itemdblclick is working. Hope am not confusing:) In simple words, the two controllers are working separately but not together.
Could anyone please tell me what am i doing wrong here.
Also, in the function editRegion in the controller, am trying to reload the tree by using the getStore.load() method, but the tree is not loading even though am able to see the store being invoked in the firebug
EDIT:
Am opening a form on double-clicking the tree node, and on closing the form, i want the tree panel to be reloaded. This is what i want to happen in editregion function
View
{
xtype : 'treepanel',
title : '',
id : 'hierarchyTree',
border : false,
alias : 'widget.hierarchyTree',
height : 1000,
viewConfig : {
enableDD : true,
plugins : {
ptype : 'treeviewdragdrop'
}
},
collapsible : false,
useArrows : true,
rootVisible : false,
store : Ext.create('App.store.HierarchyTree'),
displayField : 'Title',
multiSelect : false,
singleExpand : false,
}
Controller
refs : [{
ref : 'myHierarchyTree',
selector : '#hierarchyTree'
}
init : function() {
this.getHierarchyTreeStore().load();
'#hierarchyTree' : {
itemdblclick : this.itemdblclick
},
'#hierarchyTree' : {
itemmove : this.itemmove
}
itemdblclick : function(view, record, level) {
if (record.get('LevelID') == 1) {
this.erWin = Ext.create('App.view.EditRegions');
var f = this.getEditregionform().getForm();
f.loadRecord(record);
this.erWin.showWin();
}
else if (record.get('LevelID') == 2) {
this.eaWin = Ext.create('App.view.EditAreas');
var f = this.getEditareaform().getForm();
f.loadRecord(record);
this.eaWin.showWin();
}
itemmove : function(v, oldParent, newParent, index, eOpts) {
var nodeID = v.data.id;
var oldParent = oldParent.data.id;
var newParent = newParent.data.id;
var index = index;
var level = v.data.LevelID;
Ext.Ajax.request({
url : 'data/Locations.aspx',
params : {
mode : 'MOVENODE',
currentNode : nodeID,
oldParentNode : oldParent,
newParentNode : newParent
},
success : function() {
alert(LANG.SUC);
Ext.getStore('HierarchyTree').load();
},
failure : function() {
}
});
editRegion : function(button, record) {
var fp = button.up('form');
if (fp.getForm().isValid()) {
fp.getForm().submit({
url : 'data/Locations.aspx',
params : {
mode : 'EDITREGION',
userID : ME.UserID,
RegionID : ME.RegionID
},
success : function(response) {
alert(LANG.SUC);
this.getHierarchyTreeStore().load();
},
failure : function(response) {
alert('Try again');
}
});
}
}

adding them separately will cause the first listener object to be overridden.
Fix:
'#hierarchyTree' : {
itemdblclick : this.itemdblclick,
itemmove : this.itemmove
},
You should check if the store is the same. Meaning check the id because i think the contoller initializes one store and the panel another. so check if this.getHierarchyTreeStore().id is equal with the one from treepanel. you can navigate to it from the button something like button.up().down('treepanel').getStore().id. If they are different then you should use the second method to get the store.

tried doing the following code, as using up and down will not refer to the correct view, since the tree and the forms are completely different views
var view = Ext.widget('hierarchy');
view.down('treepanel').getStore.load();
Now, even though the store is re-loading, am geting an error
TypeError: view.down("treepanel") is null
view.down('treepanel').getStore.load();

ExtJS bind to singleton object

I am trying to bind to value in defined class, to react on it change.
But no reaction happens. I extended object from data.Model, and trying to bind via links, but something doing wrong.
class with parameter:
Ext.define('Platform.core.OssStatusAdapter', {
extend : 'Ext.data.Model',
alternateClassName : [ 'OssStatusAdapter' ],
singleton : true,
fields : [ {
name : 'ossConected',
type : 'boolean',
defaultValue : false
} ]
});
Code in some class where value is changed:
OssStatusAdapter.set('ossConected',event.connected);
code where expect reaction to binding:
Ext.define('Plugin.scheduler.package.config.PackageConfigurationViewModel', {
extend : 'Ext.app.ViewModel',
...
links: {
ossAdapter: {
type: 'Platform.core.OssStatusAdapter',
create: true
}
},
...
formulas : {
canDeploy : {
bind : {
isOssUp : '{ossAdapter.ossConected}'
},
get : function(data) {
return data.isOssUp;
}
}
}
but in formula value is not changing.
What I missed?
Try to define your formula this way:
formulas: {
canDeploy: function(get) {
var connected = get('ossAdapter.ossConected');
// see if this moves when you change the record
console.log('connected', connected);
return connected;
}
}

Ext js combo box typehead crtl + v error

I have combo box and type head true. On change event I am making ajax request to get matched result.
If type there then its working fine, But If I do copy paste in the Combo then it shows result but gives and error and blocks further flow.
below is the code.
{
xtype : 'combo',
emptyText : 'Search',
id : 'search',
store : Store,
width : '50%',
minChars : 3,
typeAhead : true,
anchor : '100%',
listConfig : {
emptyText : 'No Matching results found.',

return '<div class="search">' +
'<span>{value} - {key}</span>'+
'</div>';
}
},
listeners : {
beforequery: function (record) {
// Added Condition to avoid weird JS error
if(Ext.getCmp('search').getValue() != null && Ext.getCmp('search').getValue().length <= 4){
return false;
}
},
select : function(combo, selection){
var selectedVal = selection[0].data.value;
Ext.getCmp('search').setValue( selectedVal );
},
change : function () {
if( Ext.getCmp('search').getValue() != null && Ext.getCmp('search').getValue().length > 4 ){
var searchEle = Ext.getCmp('search');
var searchType = Ext.getCmp('searchBy').getValue();
var searchText = '%';
searchText += searchEle.getValue();
Ext.Ajax.request({
loadMask : true,
url : URL,
method : 'GET',
params : {
searchText : searchText,
searchType : searchType,
},
scope : this,
success : function( response, callOptions ) {
var myTempData = Ext.decode( response.responseText );
Store.setProxy({
type : 'memory',
data : myTempData,
reader : {
type : 'json',
root : 'data',
totalProperty : 'total',
successProperty : 'success'
}
});
Store.load({
scope : this,
callback : function(records, operation, success) {
}
});
},
failure : function(response, options ) {
loadmask.hide();
Ext.Msg.alert( 'Error', genericErrorMsg );
}
});
}
}
}
The error is as below
The help is greatly appreciated. Thanks.
Json response
{"value":"Test , user # IB Tech: Strategic Change","key":"45804183"},
Finally I solved it.
There was some problem with store.
I bind it after ajax success and removed it from initial config and it got solved.
Store.load({
scope : this,
callback : function(records, operation, success) { }
});
Ext.getCmp('search').bindStore(Store);

How to get display value of field from controller in ExtJS?

I have a component on my view:
{
xtype : 'socekiliscombo',
name : 'socekilisOid',
labelSeparator : '',
anchor : '25%',
allowBlank : false,
itemId : 'socekilis',
params : {},
listeners : {
specialkey : Ext.emptyFn
}
}
What I want to do is to get this component's display value from a controller. First I tried to get the component itself, but unable to do it. I tried this:
var socekilistarihi = this.getTalihliKayitPanel().getComponent('#socekilis');
I get a value of "undefined".
You can use standard controller refferences.
Ext.define('App.controller.Controller', {
extend: 'Ext.app.Controller',
refs: [{
ref: 'socekilis',
selector: '#socekilis'
}],
getComponentValue: function(){
var component = this.getSocekilis();
var value = null;
if(component){
value = component.getValue();
}
return value;
}
});
Hope it helps.
var socekilisCombo = this.getTalihliKayitPanel().down('socekiliscombo[name="socekilisOid"]'),
socekilisComboValue;
if (socekilisCombo)
{
socekilisComboValue = socekilisCombo.getValue();
}
And check this component really on talihliKayitPanel.

Sencha Touch Controller pushing a view

I'm trying to work out why when I push a view onto a Ext.Navigation.View control, the view I push renders, but the data I push with it doesn't. The view renders a very simple DataView control with some json data (name & surname).
It'll work if I create the view explicitly through "Ext.Create" (see commented out lines in controller), but I'm sure I've done this before where you can push "xtype" of the view and any relevant properties/data for the view. Am I right?
By the way, I've tested the json coming back from the form submission callback and everything is fine. It just seems to be the view doesn't want to render the data I send it as part of the "push". Here's my code. Am I missing something?:
View:
Ext.define('MyCo.Booking.view.PatientClinicSearchResults', {
extend : 'Ext.DataView',
xtype : 'DataViewPatientSearchResults',
itemTpl : '{Name}',
store : {
fields : ['Name'],
autoLoad : true
}
})
Controller :
Ext.define('MyCo.Booking.controller.Main', {
extend: 'Ext.app.Controller',
config: {
refs: {
navViewClinics : 'NavViewClinics',
formPanelClinicPatientSearch : 'FormPanelClinicPatientSearch'
},
control: {
'NavViewClinics list' : {
itemtap : 'ClinicUserSearch'
},
'FormPanelClinicPatientSearch button' : {
tap : 'ClinicPatientSearchResults'
}
}
},
ClinicUserSearch : function(list, index, element, record) {
this.getNavViewClinics().push({ xtype : 'FormPanelClinicPatientSearch' });
},
ClinicPatientSearchResults : function(button, e) {
var form = this.getFormPanelClinicPatientSearch();
var navClinics = this.getNavViewClinics();
form.submit({
success : function(form, result) {
// var view = Ext.create('MyCo.Booking.view.PatientClinicSearchResults', {
// title : 'Search Results',
// fullscreen: true,
// store: {
// fields: ['Name'],
// data : result.items
// },
// itemTpl: '<div>{Name}</div>'
// });
// navClinics.push(view);
navClinics.push({ xtype : "DataViewPatientSearchResults",
title : 'Test',
store : {
data : result.items
}
});
}
});
}
});
JSON received from form submission callback:
{
"success" : true,
"items" : [
{
"Name": "Jon",
"Surname": "Doe"
},
{
"Name": "Karl",
"Surname": "Doe"
}
]
}
Any help would be appreciated. Thank you.
Problem solved. I removed the store declaration from the view and it worked. Just need to reference the data via the itemTpl property.

search field in a dataview in extjs

Am trying to put a search field with respect to a data view. There is a toolbar on top of the data view, which consists of a text field. On entering some text in the field, i want to call a search functionality. As of now, i have got hold of the listener to the text field, but the listener is called immediately after the user starts typing something in the text field.
But, what am trying to do is to start the search functionality only when the user has entered at least 3 characters in the text field.How could i do this?
Code below
View
var DownloadsPanel = {
xtype : 'panel',
border : false,
title : LANG.BTDOWNLOADS,
items : [{
xtype : 'toolbar',
border : true,
baseCls : 'subMenu',
cls : 'effect1',
dock : 'top',
height : 25,
items : [{
xtype : 'textfield',
name : 'SearchDownload',
itemId : 'SearchDownload',
enableKeyEvents : true,
fieldLabel : LANG.DOWNLOADSF3,
allowBlank : true,
minLength : 3
}],
{
xtype : 'dataview',
border : false,
cls : 'catalogue',
autoScroll : true,
emptyText : 'No links to display',
selModel : {
deselectOnContainerClick : false
},
store : DownloadsStore,
overItemCls : 'courseView-over',
itemSelector : 'div.x-item',
tpl : DownloadsTpl,
id : 'cataloguedownloads'
}]
Controller:
init : function() {
this.control({
// reference to the text field in the view
'#SearchDownload' :{
change: this.SearchDownloads
}
});
SearchDownloads : function(){
console.log('Search functionality')
}
UPDATE 1: i was able to get hold of the listener after three characters have been entered using the below code:
Controller
'#SearchDownload' :{
keyup : this.handleonChange,
},
handleonChange : function(textfield, e, eOpts){
if(textfield.getValue().length > 3){
console.log('Three');
}
}
any guidance or examples on how to perform the search in the store of the data view would be appreciated.
A proper way would be to subscribe yourself to the change event of the field and check if the new value has at least 3 chars before proceeding.
'#SearchDownload' :{ change: this.handleonChange }
// othoer code
handleonChange : function(textfield, newValue, oldValue, eOpts ){
if(newValue.length >= 3){
console.log('Three');
}
}
Btw. I recommend you to use lowercase and '-' separated names for id's. In your case
itemId : 'search-download'
Edit apply the filter
To apply the filter I would use filter I guess you now the field you want to filter on? Lets pretend store is a variable within your controller than you may replace the console.log() with
this.store.filter('YourFieldName', newValue);
Second param can also be a regex using the value like in the example
this.store.filter('YourFieldName', new RegExp("/\"+newValue+"$/") );
For sure you can also use a Function
this.store.filter({filterFn: function(rec) { return rec.get("YourFieldName") > 10; }});
Thanks you so much sra for your answers. Here is what i did, based on your comments
filterDownloads : function(val, filterWh){
if(filterWh == 1){
var store = Ext.getStore('CatalogueDownloads');
store.clearFilter();
store.filterBy(function (r){
var retval = false;
var rv = r.get('title');
var re = new RegExp((val), 'gi');
retval = re.test(rv);
if(!retval){
var rv = r.get('shortD');
var re = new RegExp((val), 'gi');
retval = re.test(rv);
}
if(retval){
return true;
}
return retval;
})
}
}
i think there is an example of exactly what you are trying to achive .. http://docs.sencha.com/ext-js/4-0/#!/example/form/forum-search.html
