Answer 1

The proper way to activate validation directly in the view would be:
{
xtype: 'textfield',
name: 'email',
vtype: 'email'
}
No need for regex.

Answer 2

If you storing fields as model instance, you can do.
Ext.define('User', {
extend: 'Ext.data.Model',
config: {
fields: [
{name: 'name', type: 'string'},
{name: 'emailId', type: 'string'}
{name: 'phone', type: 'string'}
]
},
validations: [
{type: 'presence', name: 'name',message:"Enter Name"},
{type: 'format', name: 'emailId', matcher: /^\w+([-+.']\w+)*#\w+([-.]\w+)*\.\w+([-.]\w+)*$/, message:"Wrong Email Format"}
]
});
Or you can just match with regular expression
var ereg = /^\w+([-+.']\w+)*#\w+([-.]\w+)*\.\w+([-.]\w+)*$/;
var testResult = ereg.test(emailId);
testResult will be true or false based on validation.

For form field validation on user input use the following regex
{
xtype: 'textfield',
allowBlank:false,
regex:/^((([a-zA-Z0-9_\-\.]+)#([a-zA-Z0-9_\-\.]+)\.([a-zA-Z\s?]{2,5}){1,25})*(\s*?;\s*?)*)*$/,
regexText:'This field must contain single or multiple valid email addresses separated by semicolon (;)',
blankText : 'Please enter email address(s)',
}
