how to make synchronous call to indexeddb method from javascript

Question

I have one method say method1 in java script that is having another method say method2 call. method2 returns one value whi

Answer 1

Don't have method2 return a value. Instead, pass a callback function to method2 which will execute once the value has been fetched:

function method2(firstData, completionCallback) {

    var dataArray = new Array();
    $.indexedDB("SelfAssessment").objectStore("First_Sheet", "readonly").each(function(elem) {
        dataArray.push(elem.value);
    }).done(function() { completionCallback(dataArray) });
}

And invoke it like this:

function method1(){
    method2(userObj.first, function(dataArray) {
        // inside a function that is called by method2 when the value is fetched
        alert("dataArray size -"+dataArray.length);

        // do everything with dataArray inside this function
    }); 
}
