chrome cookie無法設定
阿新 • • 發佈：2018-12-31
Chrome瀏覽器為了安全只支援online-cookie。也就是,本地不可以設定cookie。這是不是同源策略的設定 ？
給個例子
<html>
<head>
<script language="JavaScript" type="text/javascript">
function addCookie(objName, objValue, objHours){//新增cookie
var str = objName + "=" + escape(objValue);
if (objHours > 0) {//為0時不設定過期時間，瀏覽器關閉時cookie自動消失
var date = new Date();
var ms = objHours * 3600 * 1000;
date.setTime(date.getTime() + ms);
str += "; expires=" + date.toGMTString();
}
document.cookie = str;
alert("新增cookie成功");
}
function getCookie(objName){//獲取指定名稱的cookie的值
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]);
}
}
function delCookie(name){//為了刪除指定名稱的cookie，可以將其過期時間設定為一個過去的時間
var date = new Date();
date.setTime(date.getTime() - 10000);
document.cookie = name + "=a; expires=" + date.toGMTString();
}
function allCookie(){//讀取所有儲存的cookie字串
var str = document.cookie;
if (str == "") {
str = "沒有儲存任何cookie";
}
alert(str);
}
function $(m, n){
return document.forms[m].elements[n].value;
}
function add_(){
var cookie_name = $("myform", "cookie_name");
var cookie_value = $("myform", "cookie_value");
var cookie_expireHours = $("myform", "cookie_expiresHours");
addCookie(cookie_name, cookie_value, cookie_expireHours);
}
function get_(){
var cookie_name = $("myform", "cookie_name");
var cookie_value = getCookie(cookie_name);
alert(cookie_value);
}
function del_(){
var cookie_name = $("myform", "cookie_name");
delCookie(cookie_name);
alert("刪除成功");
