JS 从cookie集合中获取cookie

比如创建一个这种的cookie

HttpCookie newCookie = new HttpCookie("issend");                    newCookie.Values["valicode"]=num;                    newCookie.Expires = DateTime.Now.AddMinutes(5);                    context.Response.Cookies.Add(newCookie);

在JS中获取

function getNetCookie(bigname, smallname) {    var re = new RegExp("(\;|^)[^;]*(" + bigname + ")\=([^;]*)(;|$)");    var match = re.exec(document.cookie);    if (match) {        var cookieValue = match != null ? match[3] : null;        var reg = new RegExp("(^|&*)" + smallname + "=([^&]*)(&|$)");        var r = cookieValue.match(reg);        if (r != null) return r[2];    }    return null;}

在JS中调用就可以了

 例如：function getCookie(){

                 var valicode = getNetCookie("issend", "valicode");
