笔记——ios识别不了new Date的“-”

var u = navigator.userAgent;

var isiOS = !!u.match(/\(i[^;]+;( U;)? CPU.+Mac OS X/); //ios终端

if (isiOS) {

start_time = =start_time.replace(/-/g, '/');

}

ios的alert显示url:

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);

};
