[技術] javascript cookie建立與取值

在w3schools中有寫到javascript cookie操作，實際使用可用，因此紀錄一下

cookie建立

function setCookie(cname, cvalue, exdays) {
  var d = new Date();
  d.setTime(d.getTime() + (exdays*24*60*60*1000));
  var expires = "expires="+ d.toUTCString();
  document.cookie = cname + "=" + cvalue + ";" + expires + ";path=/";
}
