I've followed the documentation provided by Sencha and made myself a list of items, converted it to a navigationview and a following details page. This is a many-to-1 solution and described with the picture below:
With this solution I can send the title of the item in the list into the detailsview, and type something like this:
[code]`
Ext.define('navigation.view.PresidentDetails', {
extend: 'Ext.Panel',
xtype: 'presidentdetail',
config: {
styleHtmlContent: true,
scrollabe: 'vertical',
title: 'Details',
tpl: 'Hello {firstName}!'
}
});
`[/code]
It seems I cant use statements in this code so I can specify what content I want depending on what item I clicked on. So then my question is - how do I create a more static perspective into this? Can I create a 1-to-1 relationship instead? (See image below)
Anyone knows how to achieve this? I'm currently using MVC and this is the current state of "my" (read: Senchas) controller just to get a hang of it:
Ext.define('navigation.controller.Main', {
extend: 'Ext.app.Controller',
config: {
refs: {
main: 'mainpanel'
},
control: {
'presidentlist': {
disclose: 'showDetails'
}
}
},
showDetails: function(list, record) {
this.getMain().push({
xtype: 'presidentdetail',
data: record.data
});
}
});
This problem is now solved, and it was alot easier than I thought it would be. I looked up the itemTap event in the docs and used the index of the item as an ID and wrote this little snippet.
showDetailsonItemTap: function(list, index, target, record) {
var page;
switch(index) {
case 0:
page = 'presidentdetail';
break;
case 1:
page = 'presidentdetail2';
break;
}
this.getMain().push({
xtype: page,
data: record.data
});
console.log(index);
}
After that, its just creating views manually and hit their xtype within the switchstatement.

I use ExtJs 6.6.0 Classic. The grid component supports multi-column sorting (I use remoteSort: true, remoteFilter: true). Whenever the user clicks on a column header, that column becomes the first column in the order by list. But I cannot find how an end user is supposed to clear the sorting for a column. The context menu available through the column header doesn't have a "Clear Sort" option.
See also this kitchensink example.
I feel like I am missing something. There is a sortClearText config for the column inherited from the header, but I could not find a place where it's used (I thought that perhaps there is some config I can use to add the Clear Sort menu item to the column context menu).
I could add a button to execute the action of clearing the sorting of the store, as a last resort, but I don't like it.
Is there a simple way to add a Clear Sort option for a grid column through the Extjs components configuration?
Thank you
I also did not find, but you can use the following override:
Ext.define('overrides.grid.header.Container', {
override: 'Ext.grid.header.Container',
getMenuItems: function() {
var me = this,
menuItems = [],
hideableColumns = me.enableColumnHide ? me.getColumnMenu(me) : null;
if (me.sortable) {
menuItems = [{
itemId: 'ascItem',
text: me.sortAscText,
iconCls: me.menuSortAscCls,
handler: me.onSortAscClick,
scope: me
}, {
itemId: 'descItem',
text: me.sortDescText,
iconCls: me.menuSortDescCls,
handler: me.onSortDescClick,
scope: me
}, {
itemId: 'dropSortItem',
text: me.sortClearText,
//iconCls: me.menuSortDescCls, // Your icon
handler: me.onSortClearClick,
scope: me
}];
}
if (hideableColumns && hideableColumns.length) {
if (me.sortable) {
menuItems.push({
itemId: 'columnItemSeparator',
xtype: 'menuseparator'
});
}
menuItems.push({
itemId: 'columnItem',
text: me.columnsText,
iconCls: me.menuColsIcon,
menu: hideableColumns,
hideOnClick: false
});
}
return menuItems;
},
onSortClearClick: function() {
var menu = this.getMenu(),
activeHeader = menu.activeHeader,
store = this.up('grid').getStore();
store.getSorters().each(function(sorter) {
if(sorter.initialConfig.property == activeHeader.dataIndex) {
store.getSorters().remove(sorter)
}
}, this);
}
});
So I'm trying to put items dynamically to the panel that has slidenavigation feature:
// FlyoutNavigation.js
Ext.define("APN.view.FlyoutNavigation", {
id: "flyoutNavigationPanel",
extend: 'Ext.ux.slidenavigation.View',
Here is the initialisation of the view in another view:
// MainViewContainer.js
this.home = "Some var"
this.flyout = Ext.create('APN.view.FlyoutNavigation', {
id: 'flyoutNavigationPanel',
home: this.home
});
Than I'm trying to use this variable in the this.config.items section, however that doesn't work, it seems that Sencha compiles everything first and than initialiases the components, I might be wrong, I'm really new to Sencha Framework.
So here is the view where the home variable is used:
Ext.define("APN.view.FlyoutNavigation", {
id: "flyoutNavigationPanel",
extend: 'Ext.ux.slidenavigation.View',
xtype: 'flyoutnavigation',
requires: [
... heaps of things omitted ...
],
initialize: function () {
this.callParent();
this.setupDynamicItems();
},
config: {
items: [
{
itemId: 'nav_home',
id: 'homeView',
items: [{
xtype: 'articlelist',
id: 'latestNews',
feedUrlName: this.home, // - that's the place where UNDEFINED occurs
flex: 1
}
],
},
So this.home is undefined...
One possible solution
Comming from this question: How to dynamically create xtype templates in Sencha Touch
I decided to put all the code in this.config.items.add({ ... my items ... }) however Ext.ux.slidenavigation.View looks like gave me the BUG! :( as the initialise method occurs after the binding methods on items of FlyoutNavigation view.
Here is the message from of the bug: Uncaught TypeError: Cannot read property 'raw' of undefined View.js:310 which is basically this line: if (Ext.isFunction(item.raw.handler)) {
So my questions would be
How to get the instance variable in the config.items section? If that's possible, than all is OK
Or do you know the work around of this issue?
Thanks
I don't think you can use this.config when defining the class, instead you can use initialize function as I told you earlier. So you should be able to do this:
initialize : function() {
var me = this;
var home = me.config.home;
me.add({
itemId: 'nav_home',
id: 'homeView',
items: [{
xtype: 'articlelist',
id: 'latestNews',
feedUrlName: home,
flex: 1
}
],
});
}
OR if you have defined homeView in parent class, you can do this:
initialize : function() {
var me = this;
var home = me.config.home;
me.down('#homeView').add({
xtype: 'articlelist',
id: 'latestNews',
feedUrlName: home,
flex: 1
});
}
I have a simple view that has a list on the left and a container to show details of the tapped list item on the right defined as such:
Ext.define('app.view.activity.ListContainer', {
extend: 'Ext.Container',
alias: 'widget.activitylistcontainer',
requires: [
'app.view.activity.List',
'app.view.activity.ListDetail'
],
config: {
layout: {
type: 'hbox'
},
items: [
{
xtype: 'activitylist',
flex: 4
},
{
xtype: 'activitylistdetail',
flex: 5
}
]
}
});
When the activity.List Store loads, I want activity.ListDetail to show the details of the first Record in the Store. My problem is that I cannot get to activity.ListContainer because it is not being recognised as the parent of activity.List.
onActivityListInitialize: function(component, options){
var activityStore = Ext.create('app.store.Activity');
activityStore.on('load', function(store, records, successful, operation, eOpts){
var activityListHasContainer = component.hasParent(),
activityListContainer = component.getParent(),
activityListContainerUp = component.up('activitylistcontainer');
console.log(component, component.parent, activityListHasContainer, activityListContainer, activityListContainerUp);
});
component.setStore(activityStore);
}
The output of the console.log is Object, undefined, false, undefined, undefined. I included component.parent in the log because when I inspect the object there is a parent property, but for whatever reason it shows undefined when logged out.
Could someone help shed some light on this? Is activity.ListContainer not considered a parent of activity.List in Sencha? Or is it something else in my app that is screwing with this? If it helps, activity.ListContainer is inside a navigationview
Turns out activity.ListContainer does not exist at the time the activity.ActivityList initialize event is triggered. My solution is to move this method to the activity.ListContainer initialize event.
I am using the MVC architecture (i have gone through the docs on MVC, but i am still lost here) and i need to know how to populate the records on to my Label. I know that i have to get this done by Stores.
I have loaded the values from the store, but unable to display it on my Panel for some reason. here's my code;
Most of the examples/books demonstrates how to display in a grid, but not a label (I know it has to be the same logic, but i am lost). And it shows how to write to a DB/JSON file and not display the values.
I need to display the COUNTRYNAME in the Label text. This is an example code that i am doing to understand this, can some one help me ?
Ext.define ('ProjectDisplayExample.model.Country',{
extend: 'Ext.data.Model',
//
fields:['countryid','countryname']
//
});
STORE
Ext.define('ProjectDisplayExample.store.Country',{
extend:'Ext.data.Store',
model:'ProjectDisplayExample.model.Country',
remoteGroup:true,
proxy: {
actionMethods : {
read : 'POST',
},
type: 'ajax',
url : '/server/country.php'
}
});
VIEW
Ext.define('ProjectDisplayExample.view.CountryWindow', {
extend: 'Ext.window.Window',
alias: 'widget.countrywindow',
...........
initComponent: function() {
var st = Ext.getStore('Country');
st.load();
this.items = [
{
items: [
{
xtype: 'panel',
region: 'north',
items: [{
xtype: 'label',
// NEED TO DISPLAY COUNTRT NAME FROM THE STORE HERE
}]
}]
}
UPDATE
var store = ... // Your store
store.on('load', function() {
// here store is loaded and you can do anything you want with it
console.log('store is loaded. number of records = ', store.getCount());
}, this, { single: true });
store.load; // I ADDED THIS LINE.................... <---------
UPDATE 2
this.items = [
{
items: [
{
xtype: 'panel',
region: 'north',
items: [{
xtype: 'label',
name : f
}]
}]
I will not post a code sample to exactly solve your question, but I will give you couple points:
Store contains array or records. So you can't just say give me country name from the store. You need first to get a record, for example: var r = store.getAt(0), and only after that you can get countyname field var f = r.get('countryname').
Load() method is asynchronous, so you can just execute it somewhere in the code and assume that for the very next line your store is ready. You need to subscribe to the load event, something like:
var store = ... // Your store
store.on('load', function() {
// here store is loaded and you can do anything you want with it
console.log('store is loaded. number of records = ', store.getCount());
}, this, { single: true });
store.load();
Labels as in xtype: label are actually very rarely used in ExtJs. What exactly are you trying to display in that panel? But anyhow... after you get data out of the store you can use something like update() or setValue() or any other method to update component.
Hope this helps...
I am getting problem that how to implement search field on tree store getting data from the server in sencha touch.Any working code will be appreciated.
In Search field You can use key up event and filter a store as type charterer match to store and show filter data in list and on select on item in list you hide list as bellow done
{
xtype: 'searchfield',
name : 'Name',
label: 'Name: ',
id : 'Name',
record:'Details',
placeHolder: 'Name',
listeners: {
focus: function( field, e, eOpts ){
Ext.getCmp('FilterDropDown').show();
},
keyup: function(field) {
var value = field.getValue();
var Store = Ext.getStore('Details');
var FilterStore = Ext.getStore('FilterDetails');
FilterStore.removeAll();
count=0;
var thisRegEx = new RegExp(value, 'i');
for(cnt=0;cnt<Store.getCount();cnt++){
if(thisRegEx.test(Store.data.items[cnt].data.name)){
FilterStore.add({
'id':Store.data.items[cnt].data.id,
'name': Store.data.items[cnt].data.name,
'email': Store.data.items[cnt].data.email
});
}
}
}
}
},
{
xtype:'FilterList',
id: 'FilterDropDown',
height:200,
hidden : true,
listeners: {
itemtap: function( field, index, target, record, e, eOpts ){
Ext.getCmp('Name').setValue(record.data.name);
Ext.getCmp('Email').setValue(record.data.email);
Ext.getCmp('Mobile').setValue(record.data.mobileno);
Ext.getCmp('FilderDropDown').hide();
}
}
},
xtype FilterList code is
Ext.define('appname.view.FilterList', {
extend: 'Ext.dataview.List',
xtype: 'FilterList',
require: ['FilterDetails'],
config:{
store: 'FilterDetails',
scrollable: true,
cls: 'drop_down_list',
ui: 'round',
itemTpl: '<div>{name}</div>'
}
});
It will help you :)
Assuming the data is already in the store when you search this isn't too difficult to implement using the methods referenced by speznaz.
In your view have a xtype "searchfield" or "textfield".
{
xtype: "searchfield",
}
In the controller bind a "keyup" event to this field.
refs: {
searchfield: 'mypanel searchfield'
},
control: {
searchfield: {
keyup: 'doSearch'
}
}
For your function to search something like:
doSearch: function(searchfield, e, eOpts) {
var searchterm = searchfield.getValue();
var store = Ext.getStore('myStore');
// Now just customise the search options
store.find(fieldName, value, [startIndex], [anyMatch], [caseSensitive], [exactMatch] );
}
This is assuming you want to search on keyup. You may want to use the "action" event instead.
Assuming you already have data in the store.
Here is the working code:
{
xtype: "searchfield",
name:'searchName'
}
In the controller bind a "keyup" event to this field.
refs: {
searchName: 'searchfield[name=searchName]'
},
control: {
searchName: {
keyup: 'doSearch'
}
}
For your function to search :
doSearch: function(field, e, eOpts) {
var searchterm = field.getValue();
var store = Ext.getStore('myStore');
// Now just customise the search options
store.filter(fieldName,searchterm);
}
Use try.sencha.com it has lot of examples on how to use the framework.
You need to use an Ajax store for getting data from server. I think this guide will be a good start for that, it also implements a tree store.
This example explains how to filter data in a list based on what you type in a searchfield.
Hope it helps
