Question

if (typeof response == "object") {
    store = new dojo.data.ItemFileReadStore({
        data : response
    });
    console.warn("Loaded to Store");
    var itemArray = new Array();
    var completed = function(items) {
        for(var i = 0; i < items.length; i++) {
            console.log(store.getValue(items[i],"itemlabel"));
            itemArray.push(store.getValue(items[i]));
        }
    };
    var error = function() {
        console.log("Error in fetching data from Store");
    };

    store.fetch({onComplete: completed, onError: error});
    console.warn("Item count"+ itemArray.length);

So my Item Count gives Always 0 but

console.log(store.getValue(items[i],"itemlabel"));

In the callback method the above get print the value.

So if i want to populate my itemArray what can i do?

Answer 1

You’re printing itemArray.length before the array gets populated with any data in the completed function, because completed will be called asynchronously.

If you want to print the actual length of itemArray, you should do it after the for-loop in completed.
