在Android webview中处理cookies
在Android webview中处理cookies
提问于 2011-03-08 21:01:26
我写了下面的html文件
<code>
<html>
<head>
<script text ="text/javascript">
function createCookie(name,value,days) {
if (days) {
var date = new Date();
date.setTime(date.getTime()+(days*24*60*60*1000));
var expires = "; expires="+date.toGMTString();
}
else var expires = "";
document.cookie = name+"="+value+expires+"; path=/";
}
function readCookie(name) {
var nameEQ = name + "=";
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,c.length);
if (c.indexOf(nameEQ) == 0) return(c.substring(nameEQ.length,c.length));
}
return null;
}
function modifyCookie() {
var newsessid = document.getElementById('userid').value;
//var oldsessid = document.getElementById('userid').value;
if(newsessid != "") {
eraseCookie('session id') ;
createCookie('session id', newsessid, 1);
//alert(readCookie('session id'));
document.getElementById('cookies').innerHTML = readCookie('session id');
return true;
}
//.value = readCookie('session id');
}
function eraseCookie(name) {
createCookie(name,"",-1);
}
function fillTextBox() {
//alert("Running");
document.getElementById('cookies').innerHTML = readCookie('session id');
document.getElementById('userId').value = document.getElementById('sessid').value;
}
</script>
<head>
<body onload="fillTextBox()" style = "height : 480px; width : 320px; background-image : url('investmentbanking/background2.png'); background-repeat : no-repeat">
<div style = "position : absolute; left = 80px; top = 160px;">
<label style = "color : #ffffff;">Session Id :</label>
<input type="text" id="userid" name="session"/>
<br/><br/>
<input type="hidden" id ="sessid" name="user" value="truce"/>
<input type="button" onclick="modifyCookie()" value="Modify Cookie" />
<br/>
<label>Stored Cookies : <label/><label id = "cookies"/>
</div>
</body>
</html>
</code>当我在android中用我的webview打开这个文件，修改文本框的内容，点击修改cookie按钮，“cookie”旁边的文本没有改变。代码在桌面的Firefox和IE上运行正常，但在这里不能。问题是什么？

您必须初始化绑定到应用程序的CookieSyncManager实例。下面是我的：
final Context myApp = this;
CookieSyncManager.createInstance(myApp);
CookieSyncManager.getInstance().sync();只需将其添加到加载webview的活动的OnCreate()方法中。
