Ext.data.SortTypes

This class defines a series of static methods that are used on a Ext.data.Field for performing sorting. The methods cast the underlying values into a data type that is appropriate for sorting on that particular field. If a Ext.data.Field.type is specified, the sortType will be set to a sane default if the sortType is not explicitly defined on the field. The sortType will make any necessary modifications to the value and return it.

• asText - Removes any tags and converts the value to a string
• asUCText - Removes any tags and converts the value to an uppercase string
• asUCText - Converts the value to an uppercase string
• asDate - Converts the value into Unix epoch time
• asFloat - Converts the value to a floating point number
• asInt - Converts the value to an integer number

It is also possible to create a custom sortType that can be used throughout an application.

Ext.apply(Ext.data.SortTypes, {
    asPerson: function(person){
        // expects an object with a first and last name property
        return person.lastName.toUpperCase() + person.firstName.toLowerCase();
    }    
});

Ext.define('Employee', {
    extend: 'Ext.data.Model',
    fields: [{
        name: 'person',
        sortType: 'asPerson'
    }, {
        name: 'salary',
        type: 'float' // sortType set to asFloat
    }]
});
