Flex：如何检测用户是否阻止共享对象写入

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);
}
