Delete (Remove) Cookies in jQuery
The following HTML Markup consists of an HTML TextBox, a HTML Button and a HTML SPAN for adding cookie using jQuery.
Inside the jQuery document ready event handler, each button has been assigned with jQuery Click event handler.
Adding Cookies
When the Add Cookie Button is clicked, the respective jQuery event handler is executed which saves the value of the Name TextBox to browser Cookie using the $.cookie function.
The $.cookie function accepts two parameters, first the Name (Key) of the Cookie and second the Value to be stored in the Cookie.
 
Deleting Cookies
When the Delete Cookie Button is clicked, the respective jQuery event handler is executed which removes the Cookie using the $.removeCookie function.
The $.removeCookie function accepts the Name (Key) of the Cookie in order to remove the Cookie.
Name:
<input type="text" id="txtName" />
<br />
<br />
<input id="btnAdd" type="button" value="Add Cookie" />
<input id="btnDelete" type="button" value="Delete Cookie" />
<hr />
