How to read/write cookies for local file:/// HTML document?

问题

How can I read/write cookies for local file:/// HTML document using Javascript or jQuery?

I tried this one >>

function setCookie(c_name, value, exdays)
{
  var exdate = new Date();
  exdate.setDate(exdate.getDate() + exdays);
  var c_value = escape(value) + 
    ((exdays == null) ? "" : "; expires=" + exdate.toUTCString());
  document.cookie = c_name + "=" + c_value;
}

function getCookie(c_name)
{
  var i, x, y, ARRcookies = document.cookie.split(";");
  for (i = 0; i < ARRcookies.length; i++)
  {
    x = ARRcookies[i].substr(0, ARRcookies[i].indexOf("="));
    y = ARRcookies[i].substr(ARRcookies[i].indexOf("=") + 1);
    x = x.replace(/^\s+|\s+$/g, "");
    if (x == c_name)
    {
      return unescape(y);
    }
  }
}

But it does not work.

回答1:

It depends on your browser. Chrome e.g. doesn't allow cookies for local files. see: where cookie saved for local HTML file

回答2:

This will work locally

// save data value

localStorage.setItem("name", "John");

// retrieve data value

var name = localStorage.getItem("name");

If you need multiple values stored in it try this:

As an alternative to loading the page from file, you can run a webserver and load the page from localhost. Apache comes with OSX and Ubuntu. Once you have set that up you will be able to use cookies on the local page.
