JS method to clear specified cookies_javascript skills

The example in this article describes the JS method of clearing specified cookies, which is very practical. Share it with everyone for your reference.

The specific implementation code is as follows:

function GetCookieValue(name) {
  var cookieValue = null;
  if (document.cookie && document.cookie != '') {
 var cookies = document.cookie.split(';');
 for (var i = 0; i < cookies.length; i++) {
   var cookie = jQuery.trim(cookies[i]);
   //PYYH=USERNAME=steven&PASSWORD=111111&UserID=1&UserType=1
   if (cookie.substring(0, name.length + 1) == (name + '=')) {
 cookieValue = decodeURIComponent(cookie.substring(name.length + 1));
 //USERNAME=steven&PASSWORD=111111&UserID=1&UserType=1
 break;
   }
 }
  }
  return cookieValue;
}
function DelCookie(name) {
  var exp = new Date();
  exp.setTime(exp.getTime() + (-1 * 24 * 60 * 60 * 1000));
  var cval = GetCookieValue(name);
  document.cookie = name + "=" + cval + "; expires=" + exp.toGMTString();
}

function exit() {
  DelCookie("PYYH");
  window.location.replace("http://localhost:7877/index.aspx");
}
