I have a fieldset defined on my page. Now I want to enable or disable this field set on button click event. But it is not working properly. Below is the code I have written:
To Disable:
this.mySettings.query('[name="fieldsetName"]').forEach(function (field) {
field.disable();
});
To Enable:
this.mySettings.query('[name="fieldsetName"]').forEach(function (field) {
field.enable();
});
Issue-1 : When I disable fieldset, it seems to be disabled visually. But still I can access controls inside it.
Issue-2 : Once it is disabled, I cannot re-enable it.
I need a working sample with these two issues resolved.
Currently I am using version 4.2 of ExtJs
You should call the setDisabled function on the fieldset. It will disable all containing components.
fieldset.setDisabled(true);
// the fieldset and all inner components are disabled
fieldset.setDisabled(false);
// the fieldset and all inner components are enabled
See the Sencha ExtJs 4.2.0 documentation and
the following minimal working example can be found on Sencha Fiddle.
Ext.create('Ext.panel.Panel',{
items: [{
xtype: 'fieldset',
itemId: 'fieldsetId',
items: [{
xtype: 'checkbox',
fieldLabel: 'Check 1'
},{
xtype: 'checkbox',
fieldLabel: 'Check 2'
},{
fieldLabel: 'Combo 1',
xtype: 'combobox',
store: ['value1','value2','value3']
}]
}, {
xtype: 'button',
text: 'Disable fieldset',
handler: function (button) {
var fieldset = Ext.ComponentQuery.query('panel > #fieldsetId')[0];
var toggle = !fieldset.isDisabled();
var text = (toggle ? 'Enable' : 'Disable') + ' fieldset';
fieldset.setDisabled(toggle);
button.setText(text);
}
}],
renderTo: Ext.getBody()
});
Paste this into a Sencha fiddle and hit Run:
Ext.application({
name : 'Fiddle',
launch : function() {
Ext.Msg.alert('Fiddle', 'Welcome to Sencha Fiddle!');
Ext.create('Ext.window.Window', {
height: '100%',
width: '100%',
autoShow:true,
bodyPadding: 25,
title:'win',
items: [{
xtype: 'fieldset',
items: [{
xtype: 'checkbox',
fieldLabel: 'field1'
},{
xtype: 'checkbox',
fieldLabel: 'field2'
},{
fieldLabel: 'field3',
xtype: 'combo',
store: ['asdf','zzasdf','dfdf']
}]
}, {
xtype: 'button',
text: 'Enable/Disable entire fieldset',
handler: function(btn){
var fset = btn.up('window').down('fieldset');
fset.setDisabled(!fset.disabled);
}
}, {
margin: '0 0 0 10',
xtype: 'button',
text: 'Enable/Disable each field in fieldset individually',
handler: function(btn){
var fset = btn.up('window').down('fieldset');
fset.items.each(function(i){
i.setDisabled(!i.disabled);
});
}
}]
});
}
});

Even though the defaultFocus is set properly by referencing the component via #fldxyz, the component doesn't get the focus.
Ext.application({
name : 'myapp',
// autoCreateViewport is deprecated
mainView: 'myapp.MyPanel',
launch : function() {
}
});
Ext.define('myapp.MyPanel', {
extend: 'Ext.panel.Panel', // does not work
// extend: 'MyPanel', // works
layout: 'fit',
//defaultFocus: '[reference=fld]',
//defaultFocus: 'textfield:first',
defaultFocus: '#fldxyz',
items: [{
xtype: 'form',
layout: 'anchor',
items: [{
xtype: 'textfield',
fieldLabel: 'Name',
value: 'Indigo',
id: 'fldxyz',
//reference: 'fld',
selectOnFocus: true
}, {
xtype: 'textfield',
fieldLabel: 'Last',
value: 'Montoya'
}]
}]
});
I tested it with 6.6.0 and 7.2.0.
What's wrong?
Thanks
In the doc of defaultFocus is following: Specifies a child Component to receive focus when this Container's method-focus method is called.
You are not calling the focus() method and it is not focused. I have added it in the 'afterrender' listener event.
Ext.application({
name : 'myapp',
mainView: 'myapp.MyPanel'
});
Ext.define('myapp.MyPanel', {
extend: 'Ext.panel.Panel',
title: "My Form Panel",
layout: 'fit',
defaultFocus: '#fldxyz',
items: [{
xtype: 'form',
layout: 'anchor',
items: [{
xtype: 'textfield',
fieldLabel: 'Name',
value: 'Indigo',
id: 'fldxyz',
selectOnFocus: true
}, {
xtype: 'textfield',
fieldLabel: 'Last',
value: 'Montoya'
}]
}],
listeners: {
afterrender: function(formPanel) {
formPanel.focus();
}
}
});
I am trying to add an item into a fielset dynamically. I have checked the items of the fieldset in the console , the item is being added to the fieldset but it is not being displayed, I am invoking the doLayout() method for the fieldset and also for the formpanel which has this fieldset, but the size/height of the fieldset does not change. Can someone help me with this issue?
if(csType.value=="OS"){
Ext.apply(newOs,that.osCombo);
newOs.id = 'testOs2';
Ext.getCmp('cSFieldSet').add(newOs);
Ext.getCmp('cSFieldSet').setHeight(600);
Ext.getCmp('cSFieldSet').doLayout(true,true);
Ext.getCmp('cSFieldSet').ownerCt.doLayout(true,true);
that.csFormPanel.doLayout(true,true);
}
I also tried using autoHeight: true, but still the item is not being displayed
Here's some test code I just wrote to simulate what you are trying to achieve:
var simple = new Ext.FormPanel({
labelWidth: 75,
frame:true,
title: 'Simple Form',
bodyStyle:'padding:5px 5px 0',
width: 350,
defaults: {width: 230},
defaultType: 'textfield',
items: [{
// Fieldset in Column 1
xtype:'fieldset',
itemId: 'fieldSetTest',
columnWidth: 0.5,
title: 'Fieldset 1',
collapsible: false,
autoHeight:false,
defaultType: 'textfield',
items :[{
fieldLabel: 'Field 1'
}, {
fieldLabel: 'Field 2'
}, {
fieldLabel: 'Field 3'
}
]
}
],
buttons: [{
text: 'Add New Field',
handler: function() {
var newItem = new Ext.form.TextField({fieldLabel: 'New Fields'});
simple.getComponent('fieldSetTest').add(newItem);
simple.doLayout();
},
scope:this
}]
});
simple.render(document.body);
});
This works fine, so on clicking the add button the new item appears in the fieldset and the height of the fieldset automatically increases. Without seeing your whole formpanel code I can't comment much further.
I have following code-
{ fieldLabel: 'Date', name: 'Date', xtype: 'datefield' }
{ fieldLabel: 'Name', name: 'PerName', xtype: 'textfield' },
{
xtype: 'panel',
layout: 'form',
border: false,
labelWidth: 200,
items: [
this.fields.check1 = { xtype: 'checkbox', name: 'Check1', fieldLabel: 'Checkbox 1', width: 320 },
this.fields.check2 = { xtype: 'checkbox', name: 'Check2', fieldLabel: 'Checkbox 2', width: 320 }
]
}
Here, I am taking the checkboxes inside a panel as I need to increase the label width.
The label is showing but checkbox is not displaying .
What I am doing wrong
How about you add your checkboxes inside a FormPanel something like this:
var myPanel = new Ext.form.Panel({
alias: 'widget.myformPanel',
renderTo: Ext.getBody(),
defaults: {
labelWidth: 100,
},
items: [{
xtype: 'checkbox',
name: 'Check1',
fieldLabel: 'Checkbox 1'
}, {
xtype: 'checkbox',
name: 'Check2',
fieldLabel: 'Checkbox 2'
}]
});
In that way, you can set the labelWidth of the formPanel items.
Try to play it with jsfiddle.
Build your application with
sencha app build
It seems that you need to build only for deployment, however, development version uses production css. Therefore, anytime you add a new class you need to build the app to re-create css to include the new class styling.
I'd like to achieve this behavior:
If a field (combo, text, date ...) in a form panel has a custom property set true
{
xtype: 'textfield',
fieldLabel: 'Name',
name: 'Name',
customProp: true
},
then add a button or other components behind the actual component. Writen in json it would look like this:
{
xtype: 'container',
margin: '0 0 8 0',
layout: 'hbox',
items: [
{
xtype: 'textfield',
fieldLabel: 'Name',
name: 'Name',
},
{
xtype: 'button',
text: 'xxx',
tooltip: 'I\'m a custom tooltip'
}
]
}
I'm wondering how i could achieve this. Is this even possible ?
It is.
Ext.require('*');
Ext.onReady(function() {
var form = new Ext.form.Panel({
renderTo: document.body,
width: 400,
height: 100,
items: {
xtype: 'textfield',
fieldLabel: 'Foo'
}
});
setTimeout(function() {
var field = form.down('textfield');
// We have a reference to the field, let's go!
var owner = field.ownerCt;
owner.remove(field, false);
owner.add({
xtype: 'container',
layout: 'hbox',
items: [field, {
xtype: 'button',
text: 'Foo'
}]
});
}, 1000);
});
Where container is a reference to the container with the hbox layout.
I need to make an app that shows a form in a window on one screen and the main window with part of the same form - or is this is'n possible another form - on the other screen. Is this possible with ExtJs ? How ? Has anyone seen an example or perhaps an extension that does such ?
You can use a 'card' layout inside your form.
In the following example, the user sees three different pages, the first two pages have fields and the last one a button.
Clicking on the button retrieves the values from the fields. It doesn't matter that the fields are in different containers, as long as these containers are 'descendants' of the form.
Ext.application({
name : 'MyApp',
launch : function() {
Ext.create('Ext.form.Panel', {
renderTo: Ext.getBody(),
layout:'card',
activeItem: 0,
bbar: [{
text: '« Previous',
handler: function(button) {
var cardlayout = button.up('form').getLayout();
var prev = cardlayout.getPrev();
if (prev) {
cardlayout.setActiveItem(prev);
}
}
},{
text: 'Next »',
handler: function(button) {
var cardlayout = button.up('form').getLayout();
var next = cardlayout.getNext();
if (next) {
cardlayout.setActiveItem(next);
}
}
}],
items: [{
xtype: 'container',
items: [{
xtype: 'textfield',
fieldLabel: 'First name',
name: 'firstName'
}]
},{
xtype: 'container',
items: [{
xtype: 'textfield',
fieldLabel: 'Last name',
name: 'lastName'
}]
},{
xtype: 'container',
items: [{
xtype: 'button',
text: 'Submit',
handler: function(button) {
var formValues = button.up('form').getValues();
alert('Name: ' + formValues.firstName
+ ' ' + formValues.lastName);
}
}]
}]
});
}
});
