I might missing your point entirely but you just want to know whether a certain property exists?

First, thanks for your comment. ;)

My problem is: I don't know what I'll get in my result; so I need to get a list of all property names. In my example I do not know "LIC_NO". But target is to read property name and its value of property "LIC_NO" to popoulate a list.

Is it possible to fill all elements in an array or so? Or get name of property using a position number? E.g. get element name at position 0?

How about this?

function getRowProperties(rows) {
var allProperties = {};
/* iterate over your whole rows array
and execute the function for each entry
Ext.each(rows, function(row, index) {
/* This array will hold all property names
of the current row
var namesOfAllProperties = [];
// We iterate over all properties of the row
for (property in row) {
// and store the name of each property
// The array with the property names is stored in our object
allProperties[index] = namesOfAllProperties;
return allProperties;
>var list = getRowProperties(rows);
Get the list of all properties of the second row:
> list[1]
> ["LIC_NO"]

Get the first property of the second row:
> list[1][0]
> "LIC_NO"
