如何在extjs组合框中按Enter获得所选结果的值

Question

I have a combobox and i navigate through the search results using the UP/DOWN arrow keys and when i press enter on a particular result,i load a different view and i also need the value(against the valuefield)of the selected result.

I have used specialkey event and if (e.getKey() == e.ENTER) then i do a getValue() and then i load the view. But on getValue(), i get the raw value ie the string that i displayed and not the value against the valuefield(i have displayField:'Name' and valueField:'id').

I also tried firing a select event and in its listener i do a combo.getValue(), still i get the raw value and not the value against the valuefield. I need the id because i may have 2 or more search results with the same name but each one will have a unique id.

Is there a way i can get the value ?

Answer 1

the combobox hooks into 2 events of the picker which should be interesting for you:

me.mon(picker, {
    itemclick: me.onItemClick,
});

me.mon(picker.getSelectionModel(), {
    selectionchange: me.onListSelectionChange,
});

you need to hook into this events and then you should have your value
