I have a place holder which disappears only when the user starts typing. How to make it disappear when the user clicks on it.
{
xtype: 'textfield',
id: 'road',
placeHolder :'Road',
label: 'Road'
}
Please do help.

Ext.field.Select by default comes with the buttons: "Done" and "Cancel", but I need to add a third button in the middle, an "Add" button, that allows the user to insert a new option if what he needs is not in the options.
Is there a way to do this in Sencha Touch?
Thanks
Yes, it is possible. First of all, see these two documentation pages toolbar, defaultPhonePickerConfig to learn how to add custom buttons to picker toolbar.
As an example:
{
"xtype": "selectfield",
// also there is defaultTablePickerConfig
"defaultPhonePickerConfig": {
"toolbar": [
{
xtype: 'button',
text: 'Add',
align: 'left',
handler: function(){}
}
]
}
}
I would like to hide clear icon from textbox in sencha control through code.
How to do it?
Please provide sample code.
Thanks
Try this ::
{
xtype : 'textfield',
clearIcon : false,
name : 'name',
id : 'whatever'
}
There's a config property called clearIcon that you can toggle.
You can add this to you global CSS
.x-field-clearable.clear-icon-hidden .x-field-input .x-clear-icon {
display: none;
}
and then when you want to hide the clear icon of a field you just get your field and do
field.addCls('clear-icon-hidden');
Hope this helps
You can simply set the clearIcon config to false. Like this,
Ext.getCmp('ID OF THE TEXTFIELD').setClearIcon(false);
Example:
xtype: 'fieldset',
title: 'MyFieldSet',
items: [
{
xtype: 'textfield',
id: 'textfield1',
label: ''
},
Solution:
Ext.getCmp('textfield1').setClearIcon(false);
Since I'm not sure what version of Ext JS this was pertaining to, here is an update for Ext JS 6.5.x as it no longer uses clearIcon.
{
xtype: 'textfield',
itemId: 'tfLastName',
label: 'Last Name',
value: 'Allord',
*clearable: false*,
editable: false
},
This is also for the modern toolkit, per Sencha documentation; the classic toolkit doesn't have this feature.
I am trying to create a universal titlebar with a back button for my application. I am including it in the various views by using {xclass:mUserStories.view.titlebar}.
Here is the code for the titlebar:
Ext.define('mUserStories.view.titlebar', {
extend: 'Ext.TitleBar',
id: 'narwhal',
config: {
docked: 'top',
// id: 'narwhal',
title: 'CHW Module',
items: [{
ui: 'back',
text: 'Back',
id: 'backButton'
// hidden: true
}]
}
})
However, when I try to dynamically change the toolbar when switching to different pages, the console.log of the titlebar says the _title has changed but the text on the titlebar and the "hidden" property of the button does not change.
Here is the code for the logic that occurs when the button is pressed to switch the page:
toPage: function (arg) {
var t = Ext.getCmp('narwhal');
var b = Ext.getCmp('backButton');
console.log(t,b)
if (arg === PAGES.PATIENT_LIST) {
t.setTitle('Patient List');
b.setHidden(true)
}
Ext.getCmp('viewPort').setActiveItem(arg);
}
I have also tried to include a ref at the top for Narwhal : '#narwhal' and use var t = this.getNarwhal(), but this does not work either.
I am not sure if the problem lies with where the id is being kept, how the id is being called, or because the page is not refreshing properly. Any advice would help!
Thank you for your time :)
I have had the same situation in my project.
I managed to get everything to work like you want it by having a controller owning a reference to the title bar and listening to activeItemChange on my tabPanel.
Is it possible to set a mask on a textfield in ST2 ?
{
xtype: 'textfield',
name: 'phonenumber',
label: 'Your phone number',
mask: '(999) 999-9999'
},
Works in Ext but not in ST, I 'thought' ST was built on top of Ext
There's no direct property in Sencha Touch that will do this job.
So, you may need to do something like this ..
{
xtype: 'textfield',
name: 'phonenumber',
label: 'Your phone number',
placeHolder: '(999) 999-9999',
listeners : {
keyup : function( ) {
// Code that checks the i/p value according to placeHolder goes here ...
}
}
},
Btw, there's one post on Sencha Touch forum.
Hope that helps you!
New to sencha touch here. I've checked out quite a few tutorials online. I am having an issue trying to get the value of a text field. The error I am getting when I click my login button is Uncaught TypeError: Cannot call method 'getValue' of undefined. Does that mean my Ext.getCmp is undefined then? I have this panel wrapped in the regular Ext.setup....onReady:.....
var login = new Ext.Panel({
height:'auto',
scroll:'vertical',
layout:{
type:'vbox',
align:'center'
},
items:[
{
cls:'launchscreen',
html:logo,
padding:10
},
new Ext.form.FormPanel({
width:300,
cls:'loginform',
items:[
{
xtype: 'fieldset',
title: 'Login',
items: [
{
xtype: 'textfield',
name : 'username',
label: 'Username',
labelWidth: 85
},
{
xtype: 'passwordfield',
name : 'password',
label: 'Password',
labelWidth: 85
}
]
},
{
xtype: 'button',
text: 'Submit',
ui: 'confirm',
handler:function()
{
alert(Ext.getCmp('username').getValue());
}
}
]
})
]
});
EDIT: I was able to get the value if I set the id property on the text field. I've seen some example where the id isn't set and they get the value based off the name property. So I guess my question now is am I supposed to get the value based off id or name?
Using Ext.getCmp() you have to provide the ID of the element whose value you want. See Sencha API doc's for this:
getCmp( String id )
This is shorthand reference to Ext.ComponentManager.get. Looks up an existing Component by id
Parameters
id : String
The component id
You can also find the element by name, but I think it is faster by ID but perhaps also a bit expensive for the browser's engine. Can't say anything about that really.
Anyway, finding field by name is possible by using findField() method. With this method you should provide the id or name of the field that you want. See API doc: http://docs.sencha.com/ext-js/4-0/#!/api/Ext.form.Basic-method-findField
Example:
var fieldValue= Ext.getCmp("YourFormID").getForm().findField("FieldName").getValue();
