On change event Ext.form.DateField

问题

I have a Ext.form.DateField:

new Ext.form.DateField({
            id: 'date_from',
            format: 'd/m/Y',
            editable: false,
            listeners: {
            change: function (t,n,o) {
                console.log('dsd');
            }

        }
 })

However unfortunately the change event does not seem to be executed.

I have also tried:

new Ext.form.DateField({
            id: 'date_from',
            format: 'd/m/Y',
            editable: false,
            change: function (t,n,o) {
                console.log('dsd');
            }
})

However also to no avail. Any advice appreciated.

Thanks

回答1:

The change event only fires on blur. If you are trying to handle any date selection use the select event instead (in ExtJS 3.4).

And the first way is the correct way to add listeners.

you can change it into :

new Ext.form.DateField({
            id: 'date_from',
            format: 'd/m/Y',
            editable: false,
            listeners: {
            update: {
                fn:function(){
                    console.log('dsd');
                }
            }
        }
 })
