[SOLVED] Combobox and array as source

[mchrustek]

hello.
How to load data into combobox directly from array?? What I mean is:

var numbers = new Ext.form.ComboBox({
	fieldLabel: 'Choose number',
	hiddenName:'number',
	store: ['6', '7', '8', '9'],
	displayField:'year',
	typeAhead: true,
	mode: 'local',
	triggerAction: 'all',
	emptyText:'Select value...',
	selectOnFocus:true,
	width:175
});

The value should be the selected number, that's I don't need a table with 'id' and 'value'.

This has been added into 2.0 via the SimpleStore's expandData config value which expands a one-dimensional array into a record set that can be used by the store. In 1.1 there's nothing that directly supports this.

Ok. .... this is how I solved my problem:

store: new Ext.data.SimpleStore({
    fields: ['number_id', 'number'],
    data : [['6','6'],['7','7'],['8','8']]
}),

If any suggestions how to make it simplier or more "correct" - I'll wait for opinions.
And other thing - I wanted to modify this, to have data for combobox into some variable, but it doesn't work. Any idea how to do it??

(...)
var nbs = "[['6','6'],['7','7'],['8','8']]"
store: new Ext.data.SimpleStore({
    fields: ['number_id', 'number'],
    data : nbs
}),

P.S.
This forum is very helpful for me. I'm glad that into the discussions Core Developers are involved. I've already had resolved many of problems I found while 'studying' ExtJs. Thank you.

You could write a 'make2d' method:

Untested:

function make2d(arr)
{
   //possible sanity checks on arr here.
   var out = [];
   for (var i = 0; i < arr.length; i++)
      out[i] = [arr[i], arr[i]];

   return out;
}

Thanks for cooperations and suggestion. It works.

I don't see expandData in the docs.

Are these forums the only way issues are tracked? I see http://extjs.com/forum/showthread.ph...345#post119345, but am not sure if that is really supposed to be a bug report.

Also, on the same topic, are patches appropriate here?

Thanks for any tips on how to find if an issue has already been reported (and issue status).
