Cookie名称以预定义值开头

Question

I am creating cookies using javascript with the cookie name starting with SC_

For example, the following are some of the cookie names (there can be hundreds of such cookies):

• SC_item1
• SC_hello
• SC_23
• SC_a
• SC_b

Now I want to read/search all cookies (in Javascript) which are starting with prefix SC_. How can I do this?

Below is the code I am using to create cookies;

function addToCart(itemid, quantity)
{
    var cookieName = "SC_"+itemid;
    var value = "hello world";
    var exdate=new Date();
    exdate.setDate(exdate.getDate() + 365);
    var cookieValue= escape(value) + ((exdate==null) ? "" : "; expires="+exdate.toUTCString());
    document.cookie = cookieName + "=" + cookieValue;
}
