if (document.cookie.length > 0) {
c_start = document.cookie.indexOf(c_name "=")
if (c_start != -1) {
c_start = c_start c_name.length 1
c_end = document.cookie.indexOf(";", c_start)
if (c_end == -1) c_end = document.cookie.length
// document.write(document.cookie.substring. (c_start,c_end) "
");
var sss= unescape(document.cookie.substring(c_start, c_end)) // 取出值
alert(sss)
