Question

我试图在location.queryString对象中获取值我得到了两个值，我想将它们存储在一个cookie中，然后我可以在结账过程中将其传递给api。

function getParameterByName( name ){
var regexS = "[\\?&]"+name+"=([^&#]*)", 
regex = new RegExp( regexS ),
results = regex.exec( window.location.search );
if( results === null ){
return "";
} else{
return decodeURIComponent(results[1].replace(/\+/g, " "));
}
}

var mc_emailId =  getParameterByName('mc_eid');
var mc_campaignId =  getParameterByName('mc_cid');  
var mccookie = new Array([]);
document.cookie = mccookie;
alert(document.cookie);

我停了一秒钟，因为我不认为我正确地这样做是因为我想要完成的事情。在location.queryString中，我需要将两个值传递给cookie。 mc_eid和mc_cid所有代码都运行正常，但我不确定如何定位这些代码。

根据以下建议更新

  // Mail Chimp ID's Stored in Variable
  function getParameterByName( name ){
      var regexS = "[\\?&]"+name+"=([^&#]*)", 
    regex = new RegExp( regexS ),
    results = regex.exec( window.location.search );
    if( results === null ){
      return "";
    } else{
      return decodeURIComponent(results[1].replace(/\+/g, " "));
    }
  }

  var mc_emailId =  getParameterByName('mc_eid');
  var mc_campaignId =  getParameterByName('mc_cid');

  mccookie = "mc_eid=" + mc_emailId + "; mc_cid=" + mc_campaignId;
  document.cookie = mccookie;

  var days = 30;
  var d = new Date();    
  d.setTime(d.getTime()  + (days*24*60*60*1000));
  var expires =";expires="+d.toUTCString();
  document.cookie = mccookie + expires + "; path=/";

Answer 1

Cookie字符串具有每个Cookie的名称和值，例如name=value; name2=value;

对于您的代码，您可以执行类似

的操作

mccookie = "mc_eid=" + mc_emaild + "; mc_cid=" + mc_campaignId;
document.cookie = mccookie;

警告document.cookie会提醒整个cookie字符串。 W3Schools has some functions you could use to get a cookie by name or set one.

设置过期日期

var days = 30;
var d = new Date();    
d.setTime(d.getTime()  + (days*24*60*60*1000));
var expires =";expires="+d.toUTCString();

您还希望使用path在整个网站上访问Cookie。在您按上述方式设置expires和mccookie之后，您应该最终设置这样的Cookie

document.cookie = mccookie + expires + "; path=/";

getParameterByName获取值存储在cookie中
