How to remove disabled attribute in Ext JS - javascript

I have a field which is by default set as disabled. But I want to change this attribute (enable it) on button click.
{
margin: '10 50 10 50',
padding: '10 20 10 20',
xtype: 'textfield',
name: 'name',
fieldLabel: 'Survey Name',
allowBlank: false,
disabled: true,
id: 'name'
},
This is the button:
{
margin: '0 50 0 50',
padding: '10 20 10 20',
xtype: 'button',
text: "Create",
listeners: {
click: function() {
Ext.get('name').disabled = false;
}
}
}
When I click this nothing is happening. What is wrong here?

As you have provided id to your component so instead of getting by Ext.get() use Ext.getCmp().
Example
Ext.getCmp('name').setDisabled(false)
In this Fiddle, I have created a demo using same code.
Code snippet:
Ext.application({
name: 'Fiddle',
launch: function () {
Ext.create({
xtype: 'panel',
title: 'Demo',
renderTo: Ext.getBody(),
layout: 'hbox',
bodyPadding: 10,
items: [{
xtype: 'textfield',
name: 'name',
fieldLabel: 'Survey Name',
allowBlank: false,
disabled: true,
id: 'name'
}, {
xtype: 'button',
text: "Create",
listeners: {
click: function () {
Ext.getCmp('name').setDisabled(false);
}
}
}]
})
}
});
Note: Instead of using id use the itemId or any other config of extjs component because id can't be duplicate. So you can also do like this
Code snippet:
Ext.create({
xtype: 'panel',
title: 'Enable component using ITEM ID',
renderTo: Ext.getBody(),
layout: 'hbox',
bodyPadding: 10,
items: [{
xtype: 'textfield',
name: 'name',
fieldLabel: 'Survey Name',
allowBlank: false,
disabled: true,
itemId: 'name'
}, {
xtype: 'button',
text: "Create",
handler: function() {
this.up('panel').down('#name').setDisabled(false);
}
}]
})

Change textfield to textareafield

I need to change xtype from textfield to textareafield basing on a condition.
I need to do something like this, but I cant update xtype
Ext.define('app',{
launch: function(){
var i = 1;
if (i == 1) {
Ext.getCmp('myID').updateXtype('textareafield')
}
},
items:[{
xtype: 'fieldset',
title: 'title'
},
items: [{
xtype: 'textfield',
label: 'label'
}]]
})
or i can use the viewmodel, but xtype is not bindable
Ext.define('app',{
launch: function(){
var i = 1;
if (i == 1) {
this.getViewModel().set('newXtype', 'textareafield');
}
},
items:[{
xtype: 'fieldset',
title: 'title'
},
items: [{
xtype: 'textfield',
label: 'label',
bind: {
xtype: '{newXtype}'
}
}]]
})
Exactly: you cannot bind xtype in this way. In the situation I would use a hidden binding . You will build the form with textfield and textareafield. Then switch the hidden binding depending on your use case (condition).
https://fiddle.sencha.com/#view/editor&fiddle/2trf
Ext.create('Ext.form.Panel', {
title: 'Switch between textfield and textareafield',
width: 360,
bodyPadding: 10,
renderTo: Ext.getBody(),
viewModel: {
data: {
showTextfield: true
}
},
defaults: {labelWidth: 120},
tbar: [{
text: 'Switch',
handler: function(button) {
let vm = this.up('panel').getViewModel();
let showTextfield = vm.get('showTextfield');
vm.set('showTextfield', !showTextfield)
}
}],
items: [{
xtype: 'textfield',
fieldLabel: 'TEXTFIELD',
bind: { hidden: '{showTextfield}'}
},{
xtype: 'textareafield',
fieldLabel: 'TEXTAREAFIELD',
bind: { hidden: '{!showTextfield}'}
}]
});

Extjs using formBind: true, not disabling submit button

When I am using formBind: true, it does not seem to (save) and I am not sure why. Any ideas?
title: 'Edit Sessions',
modal: 'true',
items: [
{
xtype: 'form',
bodyPadding: 10,
title: "",
defaults: {
labelWidth: 90,
margin: '0 0 10 0',
anchor: '90%'
},
items: [
{
name: 'title',
xtype: 'textfield',
fieldLabel: 'Title',
allowBlank: false,
},
{
xtype: 'checkboxfield',
name: 'approved',
fieldLabel: 'Approved',
}
]
},
{
xtype: 'container',
padding: '10 10 10 10',
layout: {
type: 'hbox',
align: 'middle',
pack: 'center'
},
items:
[ //Buttons and handlers
{
xtype: 'button',
text: 'Save',
formBind: true,
type: 'submit',
margin: '5 5 5 5',
handler: function (button) {
var form = button.up().up().down('form');
form.updateRecord();
button.up('window').destroy();
}
},
{
xtype: 'button',
text: 'Cancel',
margin: '5 5 5 5',
handler: function (button) {
button.up('window').destroy();
}
}
]
}
]
The formBind only works if the button is in the form.

CLOSED -- Extjs bind selected combo from view model not work

Hello I've problem to selected by value. And the data is from viewmodel. I also search the answer on google but I not found. I am very confusing about it. Please help me.
This is my form:
Ext.define('Sipen.view.items.ItemsForm', {
extend: 'Ext.window.Window',
xtype: 'items-form',
height: 250,
width: 500,
layout: { type: 'fit' },

type: 'hbox',
align: 'stretch'
},
items: [
{
xtype: 'fieldcontainer',
flex: 1,
title: 'Item Information',
layout: 'anchor',
defaults: {
anchor: '100%',
xtype: 'textfield',
msgTarget: 'under',
labelWidht: 100,
allowBlank: false
},
items: [
{
xtype: 'hiddenfield',
name: '_id',
bind: '{currentTipe._id}'
},
{
fieldLabel: 'Code',

}
],
dockedItems: [

}
},
{
xtype: 'button',
text: 'Cancel',
listeners: {
click: 'onCancel'
}
}
]
}
]
}
]
});
Look at xtype 'combo' and I selection data by {currentItem.type_name} and the data is right, but I get error
this Uncaught TypeError: item.getId is not a function.
And this is my view model:
Ext.define('Sipen.view.items.ItemsModel', {
extend: 'Ext.app.ViewModel',
alias: 'viewmodel.items-items',
requires: [ 'Sipen.model.Items' ],
stores: {
items: {
model: 'Items',
autoLoad: true
},
typeItems: {
model: 'TypeItems',
autoLoad: true
}
}
});
Sorry for my bad english, but please help me...
============[Fixed]======================
I've found the result in here https://www.sencha.com/forum/showthread.php?302067
So the script should be like this:
{
xtype: 'combo',
name: 'type',
fieldLabel: 'Type',
valueField: 'type_name',
displayField: 'type_name',
queryMode: 'local',
forceSelection: true,
submitValue: true,
bind: {
value: '{typeItems.type_name}',
store: '{typeItems}',
selection: '{currentItem.type_name}'
}
}

How to fix default tab key navigation in Extjs 5.1?

Currently I'm working on a code migration from ExtJS 4.2 to ExtJS 5.1. And I noticed MANY changes on default behavior of many components.
One of the things I noticed is that the default tab key navigation between components has changed and in this case is not quite predictable.
To reproduce go to the 4.2 fiddle here, and then click on the first text field, hit tab and then it would change focus to state combo box; hit tab again and it would go to "Next" button, hit tab again and it would go to "Second option" radio button, and so on in a predictable order.
Then repeat the same thing on 5.1 fiddle here. First thing you'll notice is that "My First Option" radio is unchecked (that's another issue), but the main issue I would like to fix is the odd order it follows on tab key press.
How can I make tab key navigation behave as it did on 4.2 version?
Including sample code here:
// The data store containing the list of states
var states = Ext.create('Ext.data.Store', {
fields: ['abbr', 'name'],
data : [
{"abbr":"AL", "name":"Alabama"},
{"abbr":"AK", "name":"Alaska"},
{"abbr":"AZ", "name":"Arizona"}
]
});
Ext.application({
name : 'Fiddle',
launch : function() {
Ext.create('Ext.form.Panel', {
title: 'My Navigable Panel',
items: [
{
xtype: 'radiogroup',
layout: 'vbox',
items: [
{
xtype: 'radiofield',
boxLabel: 'My First Option',
name: 'radio',
value: true,
checked: true,
listeners: {
change: function(group, newValue, oldValue) {
if(newValue) {
group.up('form').down('fieldcontainer[name=containerA]').show();
group.up('form').down('fieldcontainer[name=containerB]').hide();
} else {
group.up('form').down('fieldcontainer[name=containerA]').hide();
group.up('form').down('fieldcontainer[name=containerB]').show();
}
}
},
},
{
xtype: 'fieldcontainer',
layout: 'hbox',
name: 'containerA',
fieldDefaults: {
labelAlign: 'top',
margin: '0 5 0 5'
},
items: [
{
xtype: 'textfield',
fieldLabel: 'First field',
allowBlank: false
},
{
xtype: 'combo',
fieldLabel: 'State',
width: 50,
store : states,
queryMode: 'local',
displayField: 'name',
valueField: 'abbr',
},
{
xtype: 'button',
text: 'Next'
}
]
},
{
xtype: 'radiofield',
boxLabel: 'My Second Option',
name: 'radio',
value: false
}
]
},
{
xtype: 'fieldcontainer',
padding: '0 0 0 25',
name: 'containerB',
hidden: true,
items: [{
xtype: 'radiogroup',
layout: 'vbox',
items: [
{
xtype: 'radiofield',
fieldLabel: 'My nested radio button A',
name: 'subradio'
},
{
xtype: 'radiofield',
fieldLabel: 'My nested radio button B',
name: 'subradio'
}
]
}]
}
],
renderTo: Ext.getBody()
}).show();
}
});
Well, I did not find a way to tell ExtJS 5.1 to navigate through the form as it did on 4.2, but I managed to get the desired behavior by modifying my form composition (although it looks the same) in a way that ExtJS 5.1 was able to orderly follow.
To make that happen I removed the radiogroup component but kept all that was inside of it (which was pretty much the whole form content). It seems that structure didn't feel quite natural to the updated framework.
Here is a fiddle with the mentioned changes.
Including code here:
// The data store containing the list of states
var states = Ext.create('Ext.data.Store', {
fields: ['abbr', 'name'],
data : [
{"abbr":"AL", "name":"Alabama"},
{"abbr":"AK", "name":"Alaska"},
{"abbr":"AZ", "name":"Arizona"}
]
});
Ext.application({
name : 'Fiddle',
launch : function() {
Ext.create('Ext.form.Panel', {
title: 'My Navigable Panel',
items: [
{
xtype: 'radiofield',
boxLabel: 'My First Option',
name: 'radio',
value: true,
checked: true,
listeners: {
change: function(group, newValue, oldValue) {
if(newValue) {
group.up('form').down('fieldcontainer[name=containerA]').show();
group.up('form').down('fieldcontainer[name=containerB]').hide();
} else {
group.up('form').down('fieldcontainer[name=containerA]').hide();
group.up('form').down('fieldcontainer[name=containerB]').show();
}
}
},
},
{
xtype: 'fieldcontainer',
layout: 'hbox',
name: 'containerA',
fieldDefaults: {
labelAlign: 'top',
margin: '0 5 0 5'
},
items: [

Difficulty in passing selected row from grid to new window in extjs

I have a grid panel and when the user selects the row and clicks the edit button or dbl clicks the row, I want to send the selected row to the new window. But I am having trouble in sending the data.
Here is my grid panel. (List.js)
Ext.define('MyApp.view.main.List', {
extend: 'Ext.grid.Panel',
xtype: 'mainlist',
require: [ 'MyApp.view.student.StudentForm' ],
title: 'Student Records',
scrollable: true,
margin: 20,
layout: {
type: 'vbox',
align: 'stretch'
},
reference: 'studentGrid',
frame: true,
collapsible: true,
store: 'StudentStore',
collapsible: true,
columns: [
{
text: 'Name',
dataIndex: 'name',
flex: 1
},
{
text: 'Address',
dataIndex: 'address',
flex: 1
},
{
text: 'Phone',
dataIndex: 'phone',
flex: 1
},
{
text: 'Email',
dataIndex: 'email',
flex: 1
},
{
text: 'Faculty',
dataIndex:'faculty',
flex: 1
}
],
dockedItems: [
{
xtype: 'toolbar',
dock: 'top',
items: [
{
xtype: 'button',
text: 'Add',
iconCls: 'fa fa-plus',
listeners: {
click: 'onAdd'
}
},
{
xtype: 'button',
text: 'Edit',
iconCls: 'fa fa-edit',
id: 'editButton',
listeners: {
click: 'onEdit'
}
},
{
xtype: 'button',
text: 'Delete',
iconCls: 'fa fa-trash-o',
bind: {
disabled: '{ !mainlist.selection }'
},
listeners: {
click: 'onDelete'
}
}]
}
],
// toolbar for our store filter field
tbar: [{
xtype: 'textfield',
fieldLabel: 'Search Student',
emptyText: '...type to filter',
width: 300,
listeners: {
change: 'onSearch'
},
triggers: {
clear: {
cls: 'x-form-clear-trigger',
handler: function(){
this.reset();
}
}
}
}]
});
And this my Controller (MainController.js)
createDialog: function(record)
{
if (record)
{
var form = Ext.create('MyApp.view.student.StudentForm');
form.loadRecord(record);
form.show();
}
Ext.create('MyApp.view.student.StudentForm').show();
},
onEdit: function(button, e, options){
var row = button.up('mainlist').getSelection();
debugger;
this.createDialog(row[0]);
},
And here is the pop up window where the data has to be loaded(StudentForm.js)
Ext.define('MyApp.view.student.StudentForm', {
extend: 'Ext.window.Window',
xtype: 'student-form',
height: 400,
width: 500,
layout: {
type: 'fit'
},
reference: 'form',
title: 'Add Student',
closable: true,
modal: true,
items: [{
xtype: 'form',
id : 'formId',
bodyPadding: 5,
modelValidation : true,
layout: {
type: 'vbox',
align: 'stretch'
},
items: [{
xtype: 'fieldset',
flex: 1,
title: 'Student Information',
layout: 'anchor',
defaultType: 'textfield',
defaults: {
anchor: '100%',
msgTarget: 'side'
},
items: [
{
xtype: 'hiddenfield',
name: 'id',
fieldLabel: 'Label'
},
{
fieldLabel: 'Name',
name: 'name'
},
{
fieldLabel: 'Address',
name: 'address'
},
{
fieldLabel: 'Phone',
name: 'phone'
},
{
fieldLabel: 'Email',
name: 'email'
},
{
xtype: 'combo',
fieldLabel: 'Faculty',
name: 'facultyName',
queryMode: 'local',
displayField: 'facultyName',
valueField: 'facultyName',
store: {
fields: ['facultyName'],
data: [{
facultyName: 'computing'
}, {
facultyName: 'multimedia'
}, {
facultyName: 'networking'
}]
}
}
]
}],
dockedItems: [
{
xtype: 'toolbar',
dock: 'bottom',
layout: {
pack: 'end',
type: 'hbox'
},
items: [
{
xtype: 'button',
text: 'Save',
iconCls: 'fa fa-check',
listeners: {
click: 'onSave'
}
},
{
xtype: 'button',
text: 'Cancel',
iconCls: 'fa fa-times',
listeners: {
click: 'onCancel'
}
}
]
}]
}]
});
What am I missing here?Any suggestions?
It says loadRecord() is not a function
Your MyApp.view.student.StudentForm is not actually a form. It is a window, hence there is no loadRecord method.
Instead of form.loadRecord(record); call form.down('form').loadRecord(record).
Remember, it is worth naming things what they are.
