Javascript中封装window.open解决不兼容问题

var openWindow = function(url, options) {var str = "";if (options) {options.height = options.height || 420;options.width = options.width || 550;options.left = options.left || ((screen.width - options.width) / 2); //默认为居中options.top = options.top || ((screen.height - options.height) / 2); //默认为居中for (var i in options) {str += ',' + i + '=' + options[i];}str = str.substr(1);};window.open(url, 'connect_window_'+ (+new Date), str);//参数1为url,参数2为了能可以重复弹出str = null;};//demo 1:新窗口打开我的led投光灯电源网站document.body.onclick = function(){openWindow("http://www.daermay.com/ ?rel=xuexb");}//demo 2:固定宽 并居中document.body.onclick = function(){openWindow("//www.VeVB.COm/ ?rel=xuexb",{width:888});}
