Becasue $.get is an asynchronus call. You fire $.get method and don't wait for getting response immidiately console.log will be called. if you print console.log in $.get you will get value. Read about asynchronus functions

function returnValue1(){ return $.get("test.php", function(data){ var mydata= $.parseJSON(data); return mydata.value1; }); } – Akash Bhandwalkar Jul 31 '16 at 10:54
call function returnValue1().then(function(data){ //here you will get your data }) – Akash Bhandwalkar Jul 31 '16 at 10:56
i use it like this "value1 = returnValue1();" alert(value1); it says [object Object] – Farhan Jameel Ahmed Jul 31 '16 at 11:04
yes it is promise. you have to use returnValu1().then(function(data){ //Data will contain your value }) – Akash Bhandwalkar Jul 31 '16 at 11:09
