推荐答案

您似乎正在尝试通过Magento中的JavaScript写入或更新Cookie.您也可以使用Session或Cookies使用PHP进行此操作.因为您说的是来自浏览器"，所以我假设您想要一个JavaScript解决方案.

It looks like you are trying to write to or update a cookie via JavaScript in Magento. You could also do this with PHP using Session or Cookies too. Since you said 'from browser' I am assuming you want a JavaScript solution.

基本上，您将具有Setter和Getter函数来设置cookie的名称，值和有效期，然后具有从专门命名的cookie中获取值的函数.有时您也可能具有清除或删除功能，该功能基本上会将cookie设置为过去过期.

Basically, you will have a Setter and Getter function to set the name, value, and expiration of a cookie and then a function to get the value from a specifically named cookie. Sometimes you might have a clear or delete function too that basically sets he cookie to expire in the past.

I found the following which will help you: https://magento.stackexchange.com/questions/163345/magento-2-how-to-use-cookie

require(['jquery', 'jquery/jquery.cookie', 'jquery/ui'], function($){
  setTimeout(function(){
    console.log($('input#email').val());
    var subject = $('#email').val();
    var date = new Date();
    var minutes = 60;
    date.setTime(date.getTime() + (minutes * 60 * 1000));
    if($.cookie('subject').length) {
      console.log('Updating Cookie Value: "subject", "' + subject + '"');  
      $.cookie('subject', subject, {path: '/', expires: date});
    } else {
      console.log('Setting Cookie Value: "subject", "' + subject + '"');  
      $.cookie('subject', subject, {path: '/', expires: date});
    }
  }, 3000);
});

如果您打算做很多事情，可以使用自己的功能对此进行扩展.

You can expand on this with your own functions if you plan to do it a lot.

function setCookie(k, v, e){
  var check_cookie = $.cookie(k); // Get Cookie Value
  var date = new Date();
  var minutes = e || 60;
  date.setTime(date.getTime() + (minutes * 60 * 1000));
  if(check_cookie.length){
    $.cookie(k, '', {path: '/', expires: -1});
  }
  $.cookie(k, v, {path: '/', expires: date});
}

function getCookie(k){
  return $.cookie(k);
}

function deleteCookie(k){
  $.cookie(k, '', {path: '/', expires: -1});
}

希望有帮助.
