jquery Gets the cookie value and deletes the cookie usage instance _jquery

This example describes jquery getting cookie values and removing cookie usage. Share to everyone for your reference, specific as follows:

Cookies have the specified cookie action class in jquery, and here are some questions about how to use cookies to manipulate classes, and then describe the correct ways to use them.

Incorrect value occurred while using jquery to manipulate cookies:

The result is that cookies have four different properties:

Name, content, domain, path

$.cookie (' The_cookie '); Read Cookie
$.cookie (' The_cookie ', ' the_value ');//Storage Cookie
$.cookie (' The_cookie ', ' The_value ', {expires:7} ); Store a cookie with a 7-day term
$.cookie (' The_cookie ', ', {Expires:-1});//Delete Cookie

Use:

$.cookie ("Currentmenuid", MenuID);

The domain and path were not specified.

So different cookies are generated when the domain and path are different

$.cookie ("Currentmenuid");

A problem occurs when a value is taken.

Therefore, use:

$.cookie ("Currentmenuid", "MenuID", {path: "/"});

to overwrite. A cookieid corresponds to a value in the same field.

Now let's take a look at an example

The path setting for cookies requires that if you do not set path: '/', path will be automatically set according to the directory (such as: Http://www.xxx.com/user/,path will be set to '/user ')

$.extend ({/** 1) Sets the value of the cookie to set the value of the name variable to value example $.cookie (' name ', ' value ');
2. Create a new cookie including the expiration path domain name example $.cookie (' name ', ' value ', {expires:7, path: '/', Domain: ' jquery.com ', secure:true});
3. New Cookie Example $.cookie (' name ', ' value ');
4. Delete a cookie example $.cookie (' name ', null);
5. Take a cookie (name) value to myvar var account= $.cookie (' name '); **/cookiehelper:function (name, value, options) {if (typeof value!= ' undefined ') {//name and value given, set C Ookie options = Options | |
      {};
        if (value = = null) {value = ';
      Options.expires =-1;
      } var expires = ';
        if (Options.expires && (typeof options.expires = = ' Number ' | | | options.expires.toUTCString)) {var date;
          if (typeof options.expires = = ' number ') {date = new date ();
        Date.settime (Date.gettime () + (Options.expires * 24 * 60 * 60 * 1000));
        else {date = Options.expires; } expires = '; Expires= ' + date.toutcstring (); Use expires attribute, Max-age isn't supported by IE} var path = Options.path? ';
      Path= ' + options.path: '; var domain = Options.domain? ';
      Domain= ' + options.domain: '; var secure = options.secure? ';
      Secure ': ';
    Document.cookie = [name, ' = ', encodeURIComponent (value), expires, path, domain, Secure].join (');
      else {//only name given, get cookie var cookievalue = null;
        if (document.cookie && document.cookie!= ') {var cookies = Document.cookie.split (';');
          for (var i = 0; i < cookies.length i++) {var cookie = Jquery.trim (Cookies[i]);
          Does this cookie string begin with the name we want? if (cookie.substring (0, name.length + 1) = = (name + ' = ')) {cookievalue = decodeURIComponent (cookie.substring (
            Name.length + 1));
          Break
    }} return cookievalue;

 }
  }
});
