问题:

I have created a textfield as follows;

{
  xtype:'textfield',
  name:'telephone',
  label:'Telephone'
}

Instead of popping up the default keyboard which has characters and numbers. I need the keyboard to only display the phone keypad (Only numbers). Since the textfield is about getting the phone number of the user, there's no point displaying a keyboard with characters.

回答1:

You might want to try using numberfield instead.

回答2:

Using property component of textfield:

{
  xtype:'textfield',
  component: {
    xtype: 'input',
    type: 'tel'
  },
  name:'telephone',
  label:'Telephone'
}

You also have other standard input types: email, search, date... see http://www.w3schools.com/html/html5_form_input_types.asp
