带有任意数量参数和回调上下文的问题的代码:

function SomeFunction(name) {
    this.name = name;
}
function tryMe(param1, param2) {
    console.log(this.name + ":  " + param1 + " and " + param2);
}
function tryMeMore(param1, param2, param3) {
    console.log(this.name + ": " + param1 + " and " + param2 + " and even " + param3);
}
function callbackTester(callback, callbackContext) {
    callback.apply(callbackContext, Array.prototype.splice.call(arguments, 2));
}
callbackTester(tryMe, new SomeFunction("context1"), "hello", "goodbye");
callbackTester(tryMeMore, new SomeFunction("context2"), "hello", "goodbye", "hasta la vista");

// context1: hello and goodbye
// context2: hello and goodbye and even hasta la vista

带有任意数量参数和回调上下文的问题的代码:

function SomeFunction(name) {
    this.name = name;
}
function tryMe(param1, param2) {
    console.log(this.name + ":  " + param1 + " and " + param2);

callbackTester(tryMeMore, new SomeFunction("context2"), "hello", "goodbye", "hasta la vista");

// context1: hello and goodbye
// context2: hello and goodbye and even hasta la vista

将作为参数传递的“子”函数包装在函数包装器中，以防止在调用“父”函数时计算它们。

function outcome(){
    return false;
}

function process(callbackSuccess, callbackFailure){
    if ( outcome() )
        callbackSuccess();
    else
        callbackFailure();
}

process(function(){alert("OKAY");},function(){alert("OOPS");})

当你有一个回调函数，它将被你的代码以外的东西调用，具有特定数量的参数，你想传递额外的参数，你可以传递一个包装器函数作为回调，并在包装器内部传递额外的参数。

function login(accessedViaPopup) {
    //pass FB.login a call back function wrapper that will accept the
    //response param and then call my "real" callback with the additional param
    FB.login(function(response){
        fb_login_callback(response,accessedViaPopup);
    });
}

//handles respone from fb login call
function fb_login_callback(response, accessedViaPopup) {
    //do stuff
}

最近遇到了这个问题，要得到它(特别是如果父函数有多个参数做不同的事情，与回调无关，是将回调与它的参数放在一个箭头函数中作为参数传递。

function tryMe(param1, param2) {
  alert(param1 + " and " + param2);
}

function callbackTester(callback, someArg, AnotherArg) {
  callback();
  
}

callbackTester(()=> tryMe("hello", "goodbye"), "someArg", "AnotherArg");

.．.或者简单地说，如果你没有多个参数做其他的事情。

function tryMe(param1, param2) {
  alert(param1 + " and " + param2);
}

function callbackTester(callback) {
  callback();
}

callbackTester(()=> tryMe("hello", "goodbye"));

//Suppose function not taking any parameter means just add the GetAlterConfirmation(function(result) {});
GetAlterConfirmation('test','messageText',function(result) {
                        alert(result);
    }); //Function into document load or any other click event.


function GetAlterConfirmation(titleText, messageText, _callback){
         bootbox.confirm({
                    title: titleText,
                    message: messageText,
                    buttons: {
                        cancel: {
                            label: '<i class="fa fa-times"></i> Cancel'
                        },
                        confirm: {
                            label: '<i class="fa fa-check"></i> Confirm'
                        }
                    },
                    callback: function (result) {
                        return _callback(result); 
                    }
                });
