这里还有另一种方法(它在for循环中工作):

var someVar = some_other_function();
someObj.addEventListener("click", 

function(theVar){
    return function(){some_function(theVar)};
}(someVar),

false);

因为你的事件监听器是'click'，你可以:

someObj.setAttribute("onclick", "function(parameter)");

在所有函数中都有一个特殊的变量:参数。您可以将参数作为匿名参数传递，并通过arguments变量(按顺序)访问它们。

例子:

var someVar = some_other_function();
someObj.addEventListener("click", function(someVar){
    some_function(arguments[0]);
}, false);

也可以试试这些(IE8 + Chrome。我不知道FF):

function addEvent(obj, type, fn) {
    eval('obj.on'+type+'=fn');
}

function removeEvent(obj, type) {
    eval('obj.on'+type+'=null');
}

// Use :

function someFunction (someArg) {alert(someArg);}

var object=document.getElementById('somObject_id') ;
var someArg="Hi there !";
var func=function(){someFunction (someArg)};

// mouseover is inactive
addEvent (object, 'mouseover', func);
// mouseover is now active
addEvent (object, 'mouseover');
// mouseover is inactive

希望没有拼写错误:-)

如果以后想要删除事件侦听器，那么创建对curry函数的引用是一个不错的选择。

在下面的代码中，我将说明我的意思。

// This is the curry function. We return a new function with the signature of what the click-listener expects
const handleClick = (foo, bar) => (clickEvent) => {
  console.log('we get our custom input', foo, bar);
  console.log('we get the click event too', clickEvent);
}

// We need to store a reference to the listener, making sure we are removing the correct reference later
const myListener = handleClick('foo', 'bar'); // Remember that we now return the actual event-handler


const btn = document.getElementById('btn'); // find the element to attach the listener to
btn.addEventListener('click', myListener);

// remove the event listener like this by using our reference
btn.removeEventListener('click', myListener);

下面是CodePen上的一个工作示例

你可以通过一个被称为闭包的javascript特性通过值(而不是引用)传递somevar:

var someVar='origin';
func = function(v){
    console.log(v);
}
document.addEventListener('click',function(someVar){
   return function(){func(someVar)}
}(someVar));
someVar='changed'

或者你也可以写一个普通的包装函数，比如wrapEventCallback:

function wrapEventCallback(callback){
    var args = Array.prototype.slice.call(arguments, 1);
    return function(e){
        callback.apply(this, args)
    }
}
var someVar='origin';
func = function(v){
    console.log(v);
}
document.addEventListener('click',wrapEventCallback(func,someVar))
someVar='changed'

这里wrapEventCallback(func,var1,var2)是这样的:

func.bind(null, var1,var2)
