Question

ASP.NET webforms: set cookie using jQuery on the OnSelectedIndexChanged event

Answer 1

+1 A:

Something like the following will save the value to a cookie on the change event:

$("#" + <%=YourDropDownList.ClientID %>).change(function(){
    var date = new Date();
    date.setTime(date.getTime() + (3 * 24 * 60 * 60 * 1000));
    $.cookie('cookieName', $(this).val(), { path: '/', expires: date });
});

Thanks Village. For others, can you perhaps adjust the code to remove the space between the pound and the percent?
