简单的问题是,如果用户阻止将数据写入共享对象,我如何在actionscript中检测到？
sharedObj = SharedObject.getLocal("rememberme");
这个返回始终是共享对象,但它的大小为0,即使我已阻止共享对象.
当我试图将数据保存到共享对象并刷新它时,它会抛出一个错误,因为写入被阻止.那么检查写入共享对象是否被禁用的正确方法是什么？
Error: Error #2130: Unable to flush SharedObject.
解决方法
var my_so:SharedObject = SharedObject.getLocal("mySpace");
var flushStatus:String = null;
try {
flushStatus = my_so.flush();
} catch (error:Error) {
trace("Error...Could not write SharedObject to disk\n");
}
if (flushStatus != null) {
switch (flushStatus) {
case SharedObjectFlushStatus.PENDING :
trace("Requesting permission to save object...\n");
my_so.addEventListener(NetStatusEvent.NET_STATUS,onFlushStatus);
break;
case SharedObjectFlushStatus.FLUSHED :
trace("Value flushed to disk.\n");
break;
}
}
function onFlushStatus(event:NetStatusEvent):void {
trace("User closed permission dialog...\n");
switch (event.info.code) {
case "SharedObject.Flush.Success" :
trace("User granted permission -- value saved.\n");
break;
case "SharedObject.Flush.Failed" :
trace("User denied permission -- value not saved.\n");
break;
}
my_so.removeEventListener(NetStatusEvent.NET_STATUS,onFlushStatus);
}
如果共享对象被阻止,你可以捕获错误报告,如果为0,它将转到SharedObjectFlushStatus.PENDING.
