框架（iframe）之类的元素不需要处理，脚本管理器会在其环境下执行脚本！！

var $ = window.jQuery,
events = ['contextmenu', 'dragstart', 'mouseup', 'copy', 'beforecopy', 'selectstart', 'select', 'keydown'];
function unbind(ele) {
    events.forEach(function (evt) {
        ele['on' + evt] = null;
        if ($) $(ele).unbind(evt);
    });
};
function runScript() {
    [window, document].forEach(unbind);
    events.forEach.call(document.querySelectorAll('*'), unbind);
}
window.onload = runScript;
window.onhashchange = function () {
    setTimeout(runScript, 300);
};
