js 实现类似C# 委托的那种效果

function A(p) {

}

function C(p1, p2) {

}

function D(p1,p2,p3) {

}

function B() {
    var method = arguments[0];
    var parms = [];
    for (var i = 1; i < arguments.length; i++) {
        parms.push(arguments[i]);
    }
    method.apply(this, parms);
}


function test1() {
    var p = "zhangSan";
    B(A, p);

    var p1 = "liSi", p2 = "wangWu";
    B(C, p1, p2);

    var p1 = "zhaoLiu", p2 = "liuQi", p3 = "zhouBa";
    B(D, p1, p2, p3);
}
