The example in this article describes how JavaScript detects whether browser cookies have been enabled. Share it with everyone for your reference. The specific analysis is as follows:
JavaScript detects whether the browser cookie has been activated. The code is slightly complicated. You can determine whether the cookie has been activated by writing a test cookie
var dt = new Date();
dt.setSeconds(dt.getSeconds() + 60);
document.cookie = "cookietest=1; expires=" + dt.toGMTString();
var cookiesEnabled = document.cookie.indexOf("cookietest=") != -1;
if(!cookiesEnabled) {
alert('没有启用cookie ');
} I hope this article will be helpful to everyone’s JavaScript programming design.
