去除弹窗自带url提示

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);
};
