相当于Javascript / jquery的echo（PHP）Cookie值

Question

I have a cookie named myName

In php, to print the cookie value, I can simply do

<?=$_COOKIE['myName']?>

The shortest I have found in JS is:

<script>
    document.write($.cookie('myName'));
</script>

Is there not a better/shorter way to do this? Maybe with JQuery?

I am quite new to JS and moving a site over from PHP for mobile Phonegap Build dev so can't use PHP

Answer 1

您可以使用jQuery Cookie插件（ http://plugins.jquery.com/cookie/ ）来获取Cookie，就像

$.cookie("myName")

Answer 2

If you don't want to use a plugin like jQuery $.cookie, you can do something like this

function getCookie(cookiename) {
    var cookiestring = RegExp(""+cookiename+"[^;]+").exec(document.cookie);
    return unescape(!!cookiestring ? cookiestring.toString().replace(/^[^=]+./,"") : "");
}

var value = getCookie('myName');

FIDDLE

Answer 3

And what you will find very usefull is to use the console while debugging: write in your code: console.log(document.cookie);

or

console.log($.cookie('myName'));

And see the results in the javascript console of your browser (easiest way: right click in your page, go to the last item which says "inspect element", and in the window that will open, go to the last tab, named "console".)

Answer 4

use a self executing function

<script>
    (function(){document.cookie="username=test; expires=Fri, 28 Feb 2014 12:00:00 GMT; path=/";})();
</script>
