用HTML+JS實(shí)現(xiàn)Android鬧鐘功能附Alarm代碼分享
參數(shù)：
讓客戶滿意是我們工作的目標(biāo)，不斷超越客戶的期望值來自于我們對這個行業(yè)的熱愛。我們立志把好的技術(shù)通過有效、簡單的方式提供給客戶，將通過不懈努力成為客戶在信息化領(lǐng)域值得信任、有價值的長期合作伙伴，公司提供的服務(wù)項(xiàng)目有：域名與空間、虛擬空間、營銷軟件、網(wǎng)站建設(shè)、平陽網(wǎng)站維護(hù)、網(wǎng)站推廣。
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(qiáng)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！');
