How can I pass arguments to a callback function in this specific scenario.
I have a function that gets an object with callbacks like this
function doSomething({ callbackSuccess : myFunction, callbackError : myOtherFunction})
how can I pass arguments to myFunction or to myOtherFunction?
Like, if myOtherFunction gets a msg parameter like this
function myOtherFunction(msg) {
alert(msg);
}
Thanks in advance
Just like you pass them to any other function:
function doSomething(callbacks) {
callbacks.callbackSuccess('foo', 'bar');
}
If you mean you want to pass them "at the time of passing them into doSomething":
doSomething({ callbackSuccess : function () { myFunction('foo'); }, ... });
Simplest of all:
function dosomething(callback) {
//some code-poetry;
callback(1, 2, 3); //the callback is back!!!
}
function foo(a, b, c) {//this will be my callback
alert("I got some parameters")
}
dosomething(foo); //the function call
Best explanation for a callback function:Check this
A simple defination would be:the callback function is called at a certain point in the future when some code or a function completes execution.
Try this -
// function def
function doSomething(a) {
}
// calling function
doSomething({
callbackSuccess : function() {
myFunction(msg);
},
callbackError : myOtherFunction
});
