[英]Cookie in html webview android
嗨,我需要知道如何在html Web视图上读取cookie。 我有一个要关闭的横幅,它将生成一个cookie,其想法是转到另一个页面,该页面上有横幅,他将阅读该cookie以查看用户是否已单击...
这是Cookie代码
function createCookie() {
var d = new Date();
d.setTime(d.getTime() + (1*24*60*60*1000));
var expires = "expires="+d.toUTCString();
document.cookie = "cookie=cookie ; " + expires+';path = http://www.pitstop.com.br/';
document.getElementById('banner_id').style.display='none';
}
function getCookie(cname) {
var name = cname + "=";
var ca = document.cookie.split(';');
for(var i=0; i<ca.length; i++) {
var c = ca[i];
while (c.charAt(0)==' ') c = c.substring(1);
if (c.indexOf(name) == 0) return c.substring(name.length, c.length);
}
return null;
}
function banner_cookie(){
var teste = getCookie('cookie');
if(teste !=null){
alert(teste);
document.getElementById('banner_id').style.display='none';
}else{
document.getElementById('banner_id').style.display
}
}
您有许多问题似乎源于一厢情愿和误解。
例如,您的路径错误,您需要将名称传递给Cookie脚本,而不是硬编码名称“ cookie”
您需要使用经过良好测试的cookie脚本并正确使用它。
function getCookie(name) {
var start = document.cookie.indexOf(name + "=");
var len = start + name.length + 1;
if ((!start) && (name != document.cookie.substring(0, name.length))) {
return null;
}
if (start == -1) return null;
var end = document.cookie.indexOf(';', len);
if (end == -1) end = document.cookie.length;
return unescape(document.cookie.substring(len, end));
}
function setCookie(name, value, expires, path, domain, secure) {
var today = new Date();
today.setTime(today.getTime());
if (expires) {
expires = expires * 1000 * 60 * 60 * 24;
}
var expires_date = new Date(today.getTime() + (expires));
document.cookie = name + '=' + escape(value) +
((expires) ? ';expires=' + expires_date.toGMTString() : '') + //expires.toGMTString()
((path) ? ';path=' + path : '') +
((domain) ? ';domain=' + domain : '') +
((secure) ? ';secure' : '');
}
function deleteCookie(name, path, domain) {
if (getCookie(name)) document.cookie = name + '=' +
((path) ? ';path=' + path : '') +
((domain) ? ';domain=' + domain : '') +
';expires=Thu, 01-Jan-1970 00:00:01 GMT';
}
您的脚本:
function banner_cookie(){
var teste = getCookie('showbanner')=="true";
document.getElementById('banner_id').style.display=teste?"block":"none";
}
并设置:
setCookie("showbanner","true",14,"/"); // 2 weeks accessible to all website
并删除
deleteCookie("showbanner","/");
