javascript - Write a cookie based on an URL parameter, then hide or show content based on that cookie

Question

I've searched for the answer to this question and only found half solutions to my issue.

I'm trying to write a cookie based on an URL parameter, and then hide or show page content based on if that cookie is present.

I'm trying to use js-cookie.

If someone comes to the site with the parameter ?ent=a1 attached to their url, a cookie would be written called ent_afil with the value of one. If the ent_afil cookie is present a div with the ID default-content is hidden and a div with the ID a1 is shown. If the URL parameter isn't present, no cookie is written and the default-content div remains.

function SetCookie() {
var url = window.location.search;
if(url.indexOf('?ent=a1') !== -1)
    Cookies.set('ent_afil', 'one', { expires: 5 });
}
if (Cookies.get("ent_afil") == 'one')
{
    $("#default-content").hide();
    $("#a1").show();

}
else {
    $("#default-content").show();
    $("#a1").hide();
}

删除了 CBroe 建议的功能，现在可以使用。

var url = window.location.search;
if(url.indexOf('?ent=a1') !== -1)
    Cookies.set('ent_afil', 'one', { expires: 5 });

if (Cookies.get("ent_afil") == 'one')
{
    $("#default-content").hide();
    $("#a1").show();

}
 else {
    $("#default-content").show();
    $("#a1").hide();
}
