Adding a Message Alert to an Ext JS object

I'm trying to add a message alert to an ext object but I can't seem to get it. If a user is logged in then an object is pushed with the URL and they can access it. If they're not logged in, a pop-up is supposed to appear and tell them to login.
Is there an easy way to add a pop-up to an Ext pdf link?
Code
var treeObj = [];
function loggedIn() {
if (typeof isLoggedIn != 'undefined') {
return isLoggedIn;
} else {
return false;
}
}
if (loggedIn()) {
treeObj.push({
text: 'Test File',
leaf: true,
href: '/secure/test.pdf',
cls: 'tree-pdf',
});
} else{
treeObj.push({
text: 'Test File',
leaf: true,
cls: 'tree-pdf',
listeners: {
render: function(c){
c.getEl().on('click', function(){
Ext.Msg.alert('Insufficient Rights', 'You have selected a secure resource.');
}, c);
}
}
});
}

You can try this Fiddle
Code snippet:-
Ext.application({
name: 'Fiddle',
launch: function () {
var treeObj = [],
isLoggedIn;// = true;
function loggedIn() {
if (typeof isLoggedIn != 'undefined') {
return isLoggedIn;
} else {
return false;
}
}
if (loggedIn()) {
treeObj.push({
text: 'Test File',
leaf: true,
href: '/secure/test.pdf',
hrefTarget: '_blank',
cls: 'tree-pdf',
});
} else {
treeObj.push({
text: 'Test File',
leaf: true,
cls: 'tree-pdf'
});
}
Ext.create('Ext.tree.Panel', {
renderTo: document.body,
title: 'Simple Tree',
width: 300,
height: 250,
root: {
text: 'Root',
expanded: true,
children: treeObj
},
listeners: {
beforeitemclick: function (view, record, item, index, e, eOpts) {
if (!loggedIn()) {
Ext.Msg.alert('Insufficient Rights', 'You have selected a secure resource.');
return false;
}
}
}
});
}
});

How to enable Extjs filters on page load

I want to filter my grid with different buttons that active certain filters. However they do not work on page load. Only when you select/deselect a filter option and then click the button, does the filter actually kick in.
When the page first loads and you click a button, you get the following error:
TypeError: filter is undefined
How do I enable these filter settings when the page first loads?
To recreate the error. Load the fiddle and try clicking the buttons and notice they don't work. Then activate one of the filters and try again. The buttons will work after a filter is activated.
Fiddle
Buttons
var openButton = Ext.create('Ext.Button', {
text: 'Open Topics',
handler: function () {
var filter = grid[uniqueId].filters.getFilter('TopicStateValue');
filter.setActive(true);
filter.setValue('Open/Current');
}
});
var holdButton = Ext.create('Ext.Button', {
text: 'On Hold Topics',
handler: function () {
var filter = grid[uniqueId].filters.getFilter('TopicStateValue');
filter.setActive(true);
filter.setValue('Hold');
}
});
var closedButton = Ext.create('Ext.Button', {
text: 'Closed Topics',
handler: function () {
var filter = grid[uniqueId].filters.getFilter('TopicStateValue');
filter.setActive(true);
filter.setValue('Archived/Closed');
}
});
Columns
columns: [{
text: 'Title',
width: 260,
dataIndex: 'Title',
filterable: true,
filter: {
type: 'string'
// specify disabled to disable the filter menu
//, disabled: true
}
}, {
text: 'Description',
flex: 1,
dataIndex: 'Description',
filter: {
type: 'string'
// specify disabled to disable the filter menu
//, disabled: true
}
}, {
text: 'Modified',
width: 90,
dataIndex: 'Modified',
xtype: 'datecolumn',
format: 'm/d/Y',
filter: true
}, {
text: 'Status',
width: 100,
dataIndex: 'TopicStateValue',
filter: {
active: true,
type: 'list',
value: 'Open/Current',
options: ['Open/Current', 'Archived/Closed', 'Hold']
}
}]

Just check if the filter exists before pass value to it, if not, add it like this:
var openButton = Ext.create('Ext.Button', {
text: 'Open Topics',
handler: function () {
var filter = grid[uniqueId].filters.getFilter('TopicStateValue');
if (!filter) {
filter = grid[uniqueId].filters
.addFilter({
type : 'string',
dataIndex : 'TopicStateValue'
});
}
filter.setActive(true);
filter.setValue('Open/Current');
}
});
var holdButton = Ext.create('Ext.Button', {
text: 'On Hold Topics',
handler: function () {
var filter = grid[uniqueId].filters.getFilter('TopicStateValue');
if (!filter) {
filter = grid[uniqueId].filters
.addFilter({
type : 'string',
dataIndex : 'TopicStateValue'
});
}
filter.setActive(true);
filter.setValue('Hold');
}
});
var closedButton = Ext.create('Ext.Button', {
text: 'Closed Topics',
handler: function () {
var filter = grid[uniqueId].filters.getFilter('TopicStateValue');
if (!filter) {
filter = grid[uniqueId].filters
.addFilter({
type : 'string',
dataIndex : 'TopicStateValue'
});
}
filter.setActive(true);
filter.setValue('Archived/Closed');
}
});

You need to initialize the filters manually before you use them.
Please add the below code to your grid panel.
listeners: {
beforeRender:function() {
this.filters.createFilters();
}
},
I tried that on your fiddle and it works.

How to open ionicPopup on click of ionicActionSheet option?

I am attempting to open a popup when the user hits the 'custom' button on an actionsheet and I cannot figure out how to interact between the two. My best guess is below, as when I call ng-click="showPrompt()" in the view, the popup is triggered, but when I try to do it from within the buttonClicked event on the actionsheet, it's a no-go.
.controller('TablesCtrl', function($scope, $ionicPopup, $ionicActionSheet) {
$scope.tables = [];
/* Choose Number of Guests */
$scope.showActionsheet = function($ionicPopup) {
$ionicActionSheet.show({
titleText: 'How many guests?',
buttons: [
{ text: '1' },
{ text: '2' },
{ text: '3' },
{ text: '4' },
{ text: '5' },
{ text: '6' },
{ text: 'Custom' }
],
cancelText: 'Cancel',
cancel: function() {
console.log('CANCELLED');
},
buttonClicked: function(index, $ionicPopup) {
console.log('BUTTON CLICKED', index);
if(index==6){showPrompt();}
return true;
}
});
};
/* CUSTOM Number of Guests */
$scope.showPrompt = function() {
var myPopup = $ionicPopup.show({
template: '<input type="password" ng-model="data.wifi">',
title: 'Enter Wi-Fi Password',
subTitle: 'Please use normal things',
scope: $scope,
buttons: [
{ text: 'Cancel' },
{
text: '<b>Save</b>',
type: 'button-positive',
onTap: function(e) {
if (!$scope.data.wifi) {
//don't allow the user to close unless he enters wifi password
e.preventDefault();
} else {
return $scope.data.wifi;
}
}
},
]
});
};
})

Try using $scope because that function is undefined in that context but $scope is defined via closure:
if(index==6){$scope.showPrompt();}

exjts hide column if all cells of the column are empty

I am trying to hide the column if all the cells in the column are empty. I am trying to do this in the column listener by iterating through the store but I guess the store isnt populated at that time. any suggestions to achieve this functionality?
Ext.define('com.abc.MyGrid' , {
extend: 'Ext.grid.Panel',
store : 'MyStore',
columns : [{
text : 'col1',
sortable : true,
dataIndex : 'col1'
}, {
text : 'col2 ',
sortable : true,
dataIndex : 'col2',
listeners:{
"beforerender": function(){
console.log(this.up('grid').store);
this.up('grid').store.each(function(record,idx){
// if all are null for record.get('col1')
// hide the column
console.log(record.get('col1'));
});
}
}
}
})
But this is isnt working. Basically the store loop in the column listener "before render" is not executing where as the above console(this.up('grid').store) prints the store with values.

Here you go, it doesn't handle everything but should be sufficient.
Ext.define('HideColumnIfEmpty', {
extend: 'Ext.AbstractPlugin',
alias: 'plugin.hideColumnIfEmpty',
mixins: {
bindable: 'Ext.util.Bindable'
},
init: function(grid) {
this.grid = grid;
this._initStates();
this.grid.on('reconfigure', this._initStates, this);
},
_initStates: function(store, columns) {
var store = this.grid.getStore(),
columns = this.grid.columns;
this.bindStore(store);
this.columns = columns;
if(store.getCount() > 0) {
this._maybeHideColumns();
}
},
/**
*#implement
*/
getStoreListeners: function() {
return {
load: this._maybeHideColumns
};
},
_maybeHideColumns: function() {
var columns = this.columns,
store = this.store,
columnKeysMc = new Ext.util.MixedCollection();
Ext.Array.forEach(columns, function(column) {
columnKeysMc.add(column.dataIndex, column);
});
Ext.Array.some(store.getRange(),function(record){
//don't saw off the branch you are sitting on
//eachKey does not clone
var keysToRemove = [];
columnKeysMc.eachKey(function(key) {
if(!Ext.isEmpty(record.get(key))) {
keysToRemove.push(key);
}
});
Ext.Array.forEach(keysToRemove, function(k) {
columnKeysMc.removeAtKey(k);
});
return columnKeysMc.getCount() === 0;
});
columnKeysMc.each(function(column) {
column.hide();
});
}
});
Here is an example:
Ext.create('Ext.data.Store', {
storeId:'simpsonsStore',
fields:['name', 'email', 'phone'],
data:{'items':[
{ 'name': 'Lisa', "email":"lisa#simpsons.com", "phone":"555-111-1224" },
{ 'name': 'Bart', "email":"bart#simpsons.com", "phone":"555-222-1234" },
{ 'name': 'Homer', "email":"home#simpsons.com", "phone":"555-222-1244" },
{ 'name': 'Marge', "email":"marge#simpsons.com", "phone":"555-222-1254" }
]},
proxy: {
type: 'memory',
reader: {
type: 'json',
root: 'items'
}
}
});
Ext.create('Ext.grid.Panel', {
title: 'Simpsons',
store: Ext.data.StoreManager.lookup('simpsonsStore'),
columns: [
{ text: 'Name', dataIndex: 'name' },
{ text: 'Email', dataIndex: 'email', flex: 1 },
{ text: 'Phone', dataIndex: 'phone' },
{ text: 'Says Doh', dataIndex: 'saysDoh'}
],
plugins: {ptype: 'hideColumnIfEmpty'},
height: 200,
width: 400,
renderTo: Ext.getBody()
});
You can see in the example that saysDoh column is hidden.

If you want to iterate over the store, you need to put a listener on the load event of your store. The beforerender doesn't mean that your store is already loaded.
I would put the creation of you store in the initComponent. Something like this:
Ext.define('com.abc.MyGrid', {
extend: 'Ext.grid.Panel',
columns: [{
text: 'col1',
sortable: true,
dataIndex: 'col1'
}, {
text: 'col2 ',
sortable: true,
dataIndex: 'col2'
},
initComponent: function () {
var me = this;
//Create store
var myStore = Ext.create('MyStore');
myStore.load(); // You can remove this if autoLoad: true on your store.
//Listen to load event (fires when loading has completed)
myStore.on({
load: function (store, records, success) {
store.each(function (record, idx) {
console.log(record.get('col1'));
});
}
});
//Apply the store to your grid
Ext.apply(me, {
store: myStore
});
me.callParent();
}
});

GeoExt2 - Popup Bug?

I'm using GeoExt2 (alpha) + Extjs 4.1 now to implement a map application. The thing is sometimes when I select a feature on the map, two popups are displayed. one at the bottom of the screen which has correct info and one empty in the right place. it doesn't go even I close it. I wonder if this is a bug ?
myLayer.events.on({
featureselected: function(e) {
createPopup(e.feature);
},
featureunselected: function(){
popup.destroy();
}
});
function createPopup(feature) {
popup = Ext.create('GeoExt.Popup', {
id: 'popup',
title: title,
location: feature,
});
popup.on({
close: function() {
if(OpenLayers.Util.indexOf(myLayer.selectedFeatures,
this.feature) > -1) {
selectControl.unselect(this.feature);
}
}
});
PopupTab = Ext.create('Ext.tab.Panel', {
id: 'PopupTabs',
activeTab:2,
items: [
{
title: 'Supervisor',
itemId: 'tab1',
},
{
title: 'student',
itemId: 'tab2',
items: [
{
xtype: 'label',
id: 't',
html: content,
layout: 'fit',
cls:'tabStyle'
}
]
},
],
listeners: {
tabchange: function(panel, tab) {
if (tab.popup !== undefined) { // show window after tab change
tab.popup.show();
}
}
}
});
popup.add(PopupTabs);
popup.show();
}
