Im really new to this java script and Sencha touch so sorry if this question is simple but I didn't find a way to do this.
I have a function that returns a value .
now I want to display the value from the function inside an html line.
how im calling this function from html element? how I show the value?
config: {
title: 'Me',
iconCls: 'user',
//layout: 'fit',
/* create a title bar for the tab panel */
items: [
{
docked: 'top',
xtype: 'titlebar',
title: 'Singers'
},
{
html: [
'<h1>Hi!! ' + this.setName +'</h1>'
].join("")
}
],
},
setName: function (val) {
var store =Ext.getStore('user');
var last = st.last('user');
return val=(last.get('user'));
}
});
You could use the itemId property to reference the component and then update its html property via the initialise listener.
For example:
config: {
title: 'Me',
iconCls: 'user',
//layout: 'fit',
/* create a title bar for the tab panel */
items: [
{
docked: 'top',
xtype: 'titlebar',
title: 'Singers'
},
{
itemId:'htmlContainer', //use itemIds like div ids
xtype:'container',
html: ''
}
],
/**
* #cfg listeners
* Parent Component listeners go here.
* Check sencha touch doc for more information and other available events.
*/
listeners:{
initialize: 'onInitialise'
}
},
onInitialise: function()
{
//set the html config item here
var c = this.down('#htmlContainer');
c.setHtml(this.setName());
},
setName: function (val) {
....
}

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 trying to create a list of links from a data store, and then use an XTemplate to loop through and display all the links in the data store. I am trying to display the links in a modal window. This is my code:
var win;
var tpl = new Ext.XTemplate("<p>Field1: {f1}, Field2: {f2} </p>").compile();
var data = {
f1: 'a',
f2: null
};
if(!win){
win = new Ext.Window({
el:'hello-win',
layout:'fit',
width:500,
height:300,
closeAction:'hide',
plain: true,
items: [
{
xtype: 'component',
autoEl: {
html: '<input type="text">'
},
listeners: {
render: function(_component) {
_component.getEl().on('keyup', function(e) {
//console.log(this);
console.log(this.dom.childNodes[0].value);
});
}
}
},
{
xtype: 'panel',
title: 'test',
height: 100,
bodyPadding: 10,
tpl: tpl,
data: data,
renderTo: Ext.get('hello-win')
}
]
});
}
win.show(this);
There are no errors in console, but the links never load. It just shows my modal window and my textbox, but no links. I would put in in a jsfiddle, but I don't know how (I'm new to ExtJs).
How can I display a list of links in this modal window?
You should not define renderTo in you panel config. Component defined in items array will be rendered to parent component automatically.
Your window have two items so you can not use fit layout. This layout can be used only if component have only one child component. You can remove layout definition and Ext JS framework will use auto layout or you can use some layout which support more child items, like hbox, vbox, etc.
Your code should look like this:
var win = new Ext.Window({
width:500,
height:300,
closeAction:'hide',
plain: true,
items: [
{
xtype: 'textfield',
enableKeyEvents: true,
listeners: {
keyup: function(c) {
console.log(c.getValue());
}
}
},
{
xtype: 'panel',
title: 'test',
height: 100,
bodyPadding: 10,
tpl: tpl,
data: data
}
]
});
Also you should consider using textfield component instead of creating textfield by using component with autoEl config.
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');
I am working with the Sencha touch framework and there list item component. I have only been working with this for about 2 weeks now and I can not figure out how to get the "onItemDisclosure" to open up the "detailPanel". I am trying to follow this example: http://vimeo.com/19245335. I have pasted my code below. Any help is very much appreciated.
GoW3Guide.views.detailPanel = Ext.extend(Ext.Panel, {
id: 'detailpanel',
tpl: 'Hello, {firstName}!',
dockedItems: [
{
xtype: 'toolbar',
items: [{
text: 'back',
ui: 'back',
handler: function() {
GoW3Guide.Viewport.setActiveItem('disclosurelist', {type:'slide', direction:'right'});
}
}]
}
]
});
Ext.reg('detailPanel', GoW3Guide.views.detailPanel);
GoW3Guide.views.listPanel = Ext.extend(Ext.List, {
id: 'disclosurelist',
store: GoW3Guide.ListStore,
itemTpl: '<div class="contact">{firstName} {lastName}</div>',
grouped: true,
onItemDisclosure: function(record, btn, index) {
GoW3Guide.views.detailPanel.update(record.data);
GoW3Guide.views.Guidescard.setActiveItem('detailpanel');
}
});
Ext.reg('listPanel', GoW3Guide.views.listPanel);
GoW3Guide.views.Guidescard = Ext.extend(Ext.Panel, {
fullscreen: true,
layout: 'card',
cardSwitchAnimation: 'slide',
initComponent: function() {
Ext.apply(this, {
items: [GoW3Guide.views.listPanel, GoW3Guide.views.detailPanel]
});
GoW3Guide.views.Guidescard.superclass.initComponent.apply(this, arguments);
}
});
Ext.reg('guidescard', GoW3Guide.views.Guidescard);
Are you getting any javascript errors?
According to the docs setActiveItem either needs a component instance, a number (card index), or a config object, e.g. {xtype:'detailPanel'}
If you want to make a new detail panel active try
GoW3Guide.views.Guidescard.setActiveItem({xtype:'detailpanel'});
or
GoW3Guide.views.Guidescard.setActiveItem(new GoW3Guide.views.detailPanel());
