用HTML+JS實現(xiàn)Android鬧鐘功能 附Alarm代碼分享
參數(shù):
argu:型如“key1=value1;key2=value2;......”的參數(shù)表。首先,該參數(shù)表支持rexseeNotification.show()函數(shù)的所有參數(shù),用于顯示通知(調(diào)用rexseeNotification.show()),請參見rexseeNotification。另外,該參數(shù)表增加了以下參數(shù):
forcerepeat:true或false。當(dāng)該鬧鐘是由推送信息而非頁面設(shè)定時,如果id和之前的推送信息的id重復(fù),由該參數(shù)決定是否強制重新執(zhí)行,默認(rèn)為false,即不會重復(fù)執(zhí)行任何id重復(fù)的推送信息。
command:鬧鐘響時要執(zhí)行的命令,目前支持的命令包括:
notification:發(fā)送通知,默認(rèn)值。
startApplication:啟動程序。
cleanApplicationData:清楚本程序的業(yè)務(wù)數(shù)據(jù)(私有內(nèi)存中的所有數(shù)據(jù))。
notificationimmediately:true或false,無論命令是否notification,該參數(shù)都允許系統(tǒng)在設(shè)置鬧鐘的***時間先發(fā)送一個通知,然后在指定的時間延遲后再執(zhí)行命令,默認(rèn)為false。
notificationafterexec:true或false,無論命令是否notification,該參數(shù)都允許系統(tǒng)在執(zhí)行完命令后發(fā)送一個通知,默認(rèn)為false。
alermname:鬧鐘的名稱,默認(rèn)為"defaultAlerm"。
alermfirsttime:時間戳,***次鬧鐘響(即執(zhí)行命令)的時間,如果設(shè)為0或其他小于當(dāng)前時間的時間戳,命令將立即執(zhí)行,默認(rèn)為立即執(zhí)行。
alermrepeatinterval:毫秒數(shù),***次鬧鐘響之后,間隔該時間后重復(fù)執(zhí)行命令,如果小于零,將不會重復(fù)執(zhí)行。
startApplicationUrl:如果命令為startApplication,程序啟動后訪問的URL地址。
示例:
- exseeAlarm.set('command=startApplication;startApplicationUrl=http://www.rexsee.com/rexsee/alarmClock.html;alermName=test;alermfirsttime='+(rexseeAlarm.getCurrentTime()+5000)+';title=鬧鐘測試;message=鬧鐘測試內(nèi)容;url=http://www.rexsee.com/rexsee/alarmClock.html');
- rexseeDialog.toast('設(shè)置完畢!');
