Question

I have an Ext.Data.Store. And i have a function, that need to invoke one time, when store is loaded. Only one time.
At first i did this:

function invokeMe() {
alert("!");
}

actionTemplateStore.on('load', function () {
    invokeMe();
}

But one problem isin this solution:
I really need once invoce “invokeMe”-function

Answer 1

actionTemplateStore.on('load', function () {
    if (!actionTemplateStore.actionInvoked) {
        invokeMe();
        actionTemplateStore.actionInvoked = true;
    }
}

Update: as Lloyd mentioned, you can also use {single:true} option.

actionTemplateStore.on('load', yourFunction, {single:true});
