JS提供了方便的設(shè)置cookie的辦法，但是不像PHP那般用一個$_COOKIE函數(shù)就可以直接獲取，JS需要對cookie的鍵值對進(jìn)行操作，以下是匯總的四中讀取cookie的方法
//方法一
var?acookie = document.cookie.split("; ");
function?getcookie(sname){
????for?(var?i = 0; i < acookie.length; i++) {
????????var?arr = acookie[i].split("=");
????????if?(sname == arr[0]) {
????????????if?(arr.length > 1)
????????????????return?unescape(arr[1]);
????????????else
????????????????return?"";
????????}
????}
????return?"";

//方法二
function?getcookie(objname){
????var?arrstr = document.cookie.split("; ");
????for?(var?i = 0; i < arrstr.length; i++){
????????var?temp = arrstr[i].split("=");
????????if?(temp[0] == objname)?return?unescape(temp[1]);
????}
}
//方法三
有坑：WMSEMPID=01011540;? ?EMPID=00012152;?cookiename是EMPID取的是第一個cookie。
function?getcookie(cookiename){
????var?cookiestring = document.cookie;
????var?start = cookiestring.indexof(cookiename +?'= ');
????if?(start == -1)
????????return?null;
????start += cookiename.length + 1;
????var?end = cookiestring.indexof("; ", start);
????if?(end == -1)?return?unescape(cookiestring.substring(start));
????return?unescape(cookiestring.substring(start, end));
}
//方法四
function?readcookie(name){
????var?cookievalue =?"";
????var?search = name +?"=";
????if?(document.cookie.length > 0){
????????offset = document.cookie.indexof(search);
????????if?(offset != -1){
????????????offset += search.length;
????????????end = document.cookie.indexof(";", offset);
????????????if?(end == -1) end = document.cookie.length;
????????????cookievalue = unescape(document.cookie.substring(offset, end))
????????}
????}
????return?cookievalue;文章來源：http://www.zghlxwxcb.cn/news/detail-831490.html
}
