js 关闭浏览器

使用js关闭浏览器，ios下的uc、360、qq有问题

var u = navigator.userAgent var isiOS = !!u.match(/\(i[^;]+;( U;)? CPU.+Mac OS X/); //ios终端 var isSafari = u.toLowerCase().indexOf('safari') != -1 if(isiOS) { // ios的safari支持window.close，uc、360、qq浏览器不支持 if(isSafari) { window.opener = null; window.open("","_self").close() } return } if (navigator.userAgent.indexOf("MSIE") > 0) { //close IE if (u.indexOf("MSIE 6.0") > 0) { window.opener = null; window.close(); } else { window.open('', '_top'); window.top.close(); } } else if (u.indexOf("Firefox") > 0) { //close firefox window.location.href = 'about:blank'; } else if (u.toLowerCase().indexOf("ucbrowser") > 0) { window.location.href = ''; setTimeout(()=>{ window.location.href = 'about:blank'; },0) } else { //close chrome;It is effective when it is only one. window.opener = null; window.open("","_self").close() window.location.href = 'about:blank'; }
