Usage of Cookies in ASP.NET using C# or jQuery. A cookie is a piece of data which is sent from a website and stored locally by the user’s browser. Cookies are needed because HTTP is stateless. This means that HTTP itself has no way to keep track of a user’s previous activities. One way to create state is by using cookies.
jQuery:
TO STORE:
- $(function() {
- $.cookie("myVar", "Hello World!");
- $.cookie("myVar", { path: '/' }); // Sets the cookie at the root level
- });
TO READ:
- $(function() {
- alert($.cookie("myVar"));
- });
TO DELETE:
- $(function() {
- $.removeCookie("myVar");
- $.removeCookie('myVar', { path: '/' }); // Removes the cookie from the root level
- });
CODE VIEW:
