去除手机移动端alert的时候带有的网址


window.alert = function (name) {
    var iframe = document.createElement("IFRAME");
    iframe.style.display = "none";
    iframe.setAttribute("src", 'data:text/plain,');
    document.documentElement.appendChild(iframe);
    window.frames[0].window.alert(name);
    iframe.parentNode.removeChild(iframe);
};
