//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); 
                    }
                });

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
}

你的问题不清楚。如果你在问如何以更简单的方式做到这一点，你应该看看ECMAScript第5版方法.bind()，它是Function.prototype的成员。使用它，你可以做这样的事情:

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

function callbackTester (callback) {
    callback();
}

callbackTester(tryMe.bind(null, "hello", "goodbye"));

你也可以使用下面的代码，它会在当前浏览器中不可用时添加方法:

// From Prototype.js
if (!Function.prototype.bind) { // check if native implementation available
  Function.prototype.bind = function(){ 
    var fn = this, args = Array.prototype.slice.call(arguments),
        object = args.shift(); 
    return function(){ 
      return fn.apply(object, 
        args.concat(Array.prototype.slice.call(arguments))); 
    }; 
  };
}

例子

bind() - PrototypeJS文档

function tryMe(param1, param2) {
  console.log(param1 + " and " + param2);
}

function tryMe2(param1) {
  console.log(param1);
}

function callbackTester(callback, ...params) {
  callback(...params);
}



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

callbackTester(tryMe2, "hello");

在这个简单的例子中使用curry函数。

const BTN = document.querySelector('button') const RES = document.querySelector('p') const changeText = newText => () => { RES.textContent = newText ｝ BTN。addEventListener(“点击”,changeText(点击!)) <按钮> ClickMe > < /按钮 < p >不点击< p >

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
