I want the Zulu button to be disabled until the item inside the change function has a newVal set to it. Currently the Zulu button is enabled and this is an issue because I want it to be disabled until a certain condition, ie. item.set('textstuff', newVal); is met.
What is wrong with my code? I used this post: ExtJS 6 - Bind disabled property to new records in a store for some inspiration but still need some help.
title: 'Foo',
xtype: 'Bar',
autoSelect: true,
labelWidth: 150,
listeners: {
change: function(component, newVal, OldVal) {
var view = this.up('uploadthings');
var items = view.getViewModel().getStore('things').data.items;
items.forEach(function(item) {
item.set('textstuff', newVal);
});
view.getViewModel('bindBool', true);
}
}
}, {
items: [{
xtype: 'panel',
buttons: [{
style: 'margin-right: 30px',
text: 'Zulu',
iconCls: 'x-fa fa-upload',
handler: 'xray',
bind: {
disabled: '{bindBool}'
}
}]
}]
or in your ViewModel.Js file you can add formulas and configure your bondbool,
lets say you set the bindbool at the controller : me.getViewModel().set('bindbool', true)
in your ViewModel :
formulas : {
bindbool : {
get : function(get){
var tempVar = get('bindbool'); //--> true because you set it to true
return tempVar == true ? tempVar : false;
}
}
}
By doing this you can control your viewModel outputs,
Goodluck and have fun coding Extjs

When I click on a tree record, I try to set the values of this record and set these values in the form.
In the eventcler itemclick: this.showDataFields function is triggered:
....
showDataFields: function(view, record, item, index, event) {
//got a form with fields
var panel = view.up('maintab');
console.log(panel)
//var formfield = panel.down('actionform');
//assign values from selected record to form fields
//formfield.loadRecord(record);
},
..........
In this function, view.up ('maintab') is underfined.
The maintab is Ext.tab.Panel which houses the tree.
Why can not get the topmost container and how to do it correctly?
Made an example in fiddle
thank
You should use view.up('treepanel').nextSibling().getForm().setValues(record.data) in your showDataFields function to set these values in the form.
You could have provided a better example, therefore within the limitations that were proposed.
The answer I got was this were the changes in the ActionFormTree class that got the code below:
Ext.define('Fiddle.view.ActionFormTree', {
extend: 'Ext.form.Panel',
alias: 'widget.actionformtree',
xtype: 'actionform',//mainform,
initComponent: function(){
var me = this;
Ext.apply(me,{
items: [{
xtype: 'form',
border: false,
anchor: '100%',
height: 100,
layout: {
type: 'vbox',
align: 'middle',
pack: 'center'
},
items: [{
xtype: 'textfield',
name: 'text',
fieldLabel: 'Наименование',
itemId: 'name_field',
}, {
xtype: 'textfield',
name: 'code',
fieldLabel: 'Код',
itemId: 'code_field',
}]
}],
buttons: [{
text: 'Save Changes',
scope: me,
handler: function (button) {
//Эта панель со значениями полей
form = me.down('form');
var mainpanel = me.up('#maincontainer');
var treeform = mainpanel.down('usertree');
var sel = treeform.getSelectionModel().getSelection()[0];
store = treeform.getStore();
console.log(treeform)
store.suspendAutoSync()
var child = sel.set({
text: 'Измененное',
leaf: true
});
sel.expand()
store.resumeAutoSync();
//var currRecord = form.getRecord();
//if (currRecord) {
// form.updateRecord();
// form.reset();
//}
}
}]
});
me.callParent(arguments);
}
});
So, in this example, for it to work, you will need to have a node selected to work.
Hope it helps and finalize your question.
Sample to your code
I've just started working with Sencha Touch over the past couple days and I've run into a few questions. The main one is, when working with anything that doesn't regularly have user click interaction (titlebar, html text, etc for some random examples), is it possible to click on things like this and get a panel to appear.
I know that with buttons and other things, you have a tap, itemtap, etc, but I'm not sure about instances like this. Any help would be appreciated with examples.
Yes you can. Check out my blog post here: http://www.senchahackers.com/touch/multiple-tap-listeners-one-xtemplate/ that explains exactly how to do that.
Basically you can listen for a tap event on any element, as long as you add it to the list of 'delegates'
In your view:
listeners: {
tap: {
element: 'element',
delegate: '.app-box, .doc-box, .bubble-holder',
fn: function(e){
var url = e.target.name,
divClassName = e.delegatedTarget.className,
appbox = "app-box",
docbox = "doc-box",
bubble = "bubble-holder";
console.log(divClassName);
switch(divClassName){
case docbox :
//lets say you have an element '.doc-box' that you want to click and show the panel
// show the panel, which is a separate file, shown below
var profileController = YourApp.getController('YourController');
//call the showProfilePanelPopup() method in your controller, passing in this as the element that shows it
profileController.showProfilePanelPopup(this);
break;
case appbox :
alert(appbox);
break;
case bubble :
alert(bubble);
break;
}
}
}
}
Then in your controller:
extend: 'Ext.app.Controller',
config: {
refs: {
profilePanelPopup: {
autoCreate: true,
selector: '#profilePanelPopup',
xtype: 'profilePanelPopup'
}
}
},
showProfilePanelPopup: function(btn, action, values) {
var me = this;
var popup = me.getProfilePanelPopup();
popup.showBy(btn);
popup.on('hide', function () {
popup.destroy();
}, this);
}
Assuming you some Panel in your views directory like this:
Ext.define('App.view.ProfileNowPop', {
extend : 'Ext.Panel',
alias: 'widget.profileNowPop',
xtype: 'profilePanelPopup',
config: {
height: (Ext.os.deviceType != "Desktop") ? "35%" : 253,
cls:'profilePop',
left: '1%',
padding: 0,
top: '1%',
width: (Ext.os.deviceType != "Desktop") ? '40%' : '36%',
hideOnMaskTap: true,
modal: {
cls:'opaquemask'
},
scrollable: false,
store: 'ProfilePopStore',
model: 'App.model.ProfilePopModel',
items:[
{
xtype: 'fieldset',
items: [
{
xtype: 'textfield',
id: 'gradePopField0',
cls: 'gradePopField',
style: 'background: #f7f7f5',
listeners: {
initialize: function(ele, eOpts) {
this.setReadOnly(true);
}
}
}
]
}
]
},
initialize: function() {
this.callParent(arguments);
}
});
I am almost new to sencha touch and I have this simple question:
I have a panel with a search field and a start search button (a simple search):
items: [{
xtype: 'container',
html: '<div style="width:100%;text-align:center;"><img src="images/logo.png" style="max-width:40%;" /></div>',
},{
xtype: 'fieldset',
title: '<center>Insert your adress</center>',
cls:'ps-red',
items: [{
xtype: 'textfield',
name: 'adress',
required: true,
clearIcon: true,
}]
},{
xtype:'button',
text:'Search',
ui:'confirm-round',
margin:5,
handler:function(){
}
}]
Clicking on the search button I need to make an ajax call with the input text params, and display results to another panel. What should I write in the handler function of the button?
Ext.define('Demo.view.SearchResults', {
extend: 'Ext.Container',
xtype: 'resultcard',
config: {
layout:'fit',
cls:'ks-basic',
items: [{
xtype: 'dataview',
scrollable: 'vertical',
cls: 'dataview-basic',
store: '????',
}]
}
});
OK let us assume the store as 'SampleStore'
this is the sample call that you should write in handler function, see if it is useful to you,in this example I added push view, you can update panel if you want
handler : function(){
var navigationView = button.up('navigationview');
Ext.getStore('SampleStore').getProxy().setExtraParam('search',address);
Ext.getStore('SampleStore').load({
callback: function(record, operation, success) {
if(success && record.length) {
// here you can call any other function to update panel
navigationView.push({
xtype : 'resultcard',
record : record
});
} else {
Ext.Msg.alert('Address not found. (' + address + ')');
}
}
});
}// handler close
I am using Boxselect extended from combo box in ExtJs 4.1. Based on some condition i need to make the selection single or multi.
here is my code
bool result;
result = getData();
if(result)
{
Ext.getCmp("combo1").multiSelect =true
}
This does not change the combobox to multiselect .any ideas ?
You have to force the recreation of the picker when the multiSelect option change. For that, you need to delete the property picker of your combo:
combo.multiSelect = true;
delete combo.picker;
Complete example:
Ext.widget('panel', {
renderTo: Ext.getBody(),
layout: {type: 'vbox', align: 'center'},
margin: 10,
defaults: {width: 200, margin: 5},
items: [{
xtype: 'combo',
store: ['Foo', 'Bar', 'Baz']
},{
xtype: 'displayfield',
fieldLabel: 'Multiselect is',
value: "OFF"
},{
xtype: 'button',
text: "Toggle multiselect",
handler: function() {
var panel = this.up(),
combo = panel.down('combo'),
outField = panel.down('displayfield'),
newValue = !combo.multiSelect;
combo.multiSelect = newValue;
// force recreation of picker
delete combo.picker;
outField.setValue(newValue ? "ON" : "OFF");
}
}]
});
Try with the Ext.apply method.
combo = Ext.getCmp.....
Ext.apply(combo, {multiSelect: true});
I have following problem. I have grid with tbar. Inside tbar I have number of Ext.form.field.Trigger.
When the user click on trigger button I want to filter the store using function that is provided with grid. I want to define functionality of triggerclick inside defined class, so I can reuse this component with different grid.
So, in short I want to find the panel where clicked component is placed and call panel function, or pass reference of panel to triggerclick, or fire an event with some parameter that will calculated based on where the button was clicked, or maybe there is a better method to accomplish this.
The code (FilterField -> extension of trigger):
Ext.define('GSIP.core.components.FilterField', {
extend: 'Ext.form.field.Trigger',
alias: 'widget.filterfield',
initComponent: function() {
this.addEvents('filterclick');
this.callParent(arguments);
},
onTriggerClick: function(e, t) {
//Ext.getCmp('gsip_plan_list').filterList(); - working but dont want this
//this.fireEvent('filterclick'); - controller cant see it,
//this.filterList; - is it possible to pass scope to panel or reference to panel
//e.getSomething() - is it possible to get panel via EventObject? smth like e.getEl().up(panel)
}
});
code of panel:
Ext.define('GSIP.view.plans.PlanReqList', {
extend: 'Ext.grid.Panel',
alias: 'widget.gsip_devplan_list',
id: 'gsip_plan_list',
title: i18n.getMsg('gsip.view.PlanReqList.title'),
layout: 'fit',
initComponent: function() {
this.store = 'DevPlan';
this.tbar = [{
xtype: 'filterfield',
id: 'filter_login',
triggerCls: 'icon-user',
//scope:this - how to pass scope to panel without defining onTriggerClick here
// onTriggerClick: function() {
// this.fireEvent('filterclick'); //working event is fired but controller cant see it
// this.filterList; //this is working but i dont want to put this code in every filterfield
// },
// listeners : {
// filterclick: function(btn, e, eOpts) { //this is working
// }
// },
}];
this.columns = [{
id: 'id',
header: "Id",
dataIndex: "id",
width: 50,
sortable: true,
filterable: true
}, {
header: "Name",
dataIndex: "name",
width: 150,
sortable: true,
filterable: true
}, {
header: "Author",
dataIndex: "author",
sortable: true,
renderer: this.renderLogin,
filterable: true
}];
this.callParent(arguments);
},
filterList: function() {
this.store.clearFilter();
this.store.filter({
property: 'id',
value: this.down("#filter_id").getValue()
}, {
property: 'name',
value: this.down("#filter_name").getValue()
});
},
renderLogin: function(value, metadata, record) {
return value.login;
}
});
part of code of Controller:
init: function() {
this.control({
'attachments': {
filesaved: this.scanSaved,
}
}, {
'scan': {
filesaved: this.attachmentSaved
}
}, {
'#filter_login': {
filterclick: this.filterStore //this is not listened
}
});
},
filterStore: function() {
console.log('filtering store');
this.getPlanListInstance().filter();
},
Controller can listen to anything. Just need to specify exactly what to. But I would fire events on the panel level - add this into your trigger handler:
this.up('panel').fireEvent('triggerclicked');
