<a class="btn">go</a>
<a class="remove">remove</a>

    var btn = document.getElementsByClassName('btn')[0],
        remove = document.getElementsByClassName('remove')[0];
    var some = function (msg) {
        console.log(msg)
    };
    // bind 方法pc端有兼容性问题,请注意
    var fn = some.bind(null,'哈哈');
    btn.addEventListener('click',fn,false);
    remove.addEventListener('click',function () {
        btn.removeEventListener('click',fn,false);
    },false);
