Angular provides a model view controller framework for writing complex Javascript apps: Angular
Passing Arguments to Callback Functions
// global variable
var allUserData = [];
// generic logStuff function that prints to console
function logStuff (userData) {
if ( typeof userData === "string")
{
console.log(userData);
}
else if ( typeof userData === "object")
{
for (var item in userData) {
console.log(item + ": " + userData[item]);
}
}
}
// A function that takes two parameters, the last one a callback function
function getInput (options, callback) {
allUserData.push (options);
callback (options);
}
// When we call the getInput function, we pass logStuff as a parameter.
// So logStuff will be the function that will called back (or executed) inside the getInput function
getInput ({name:"Rich", speciality:"JavaScript"}, logStuff);
// name: Rich
// speciality: JavaScript
