本文實(shí)例講述了angularjs自定義過濾器demo。分享給大家供大家參考，具體如下：
這個(gè)基于angularjs的過濾器是最近做的"信息管理學(xué)院實(shí)驗(yàn)室預(yù)約"項(xiàng)目中的一個(gè)小功能。
以下為數(shù)據(jù):
$scope['classes']=[{id:1,name:"H503",capacity:40,software:"photoshop,金蝶,AI",freeTime:"周一1-2-3,周五1-2-3,周一5-6,"}, {id:2,name:"H504",capacity:50,software:"chrome,金蝶,office," ,freeTime:"周二1-2-3,周三3-4,周一5-6,"}, {id:3,name:"H505",capacity:60,software:"chrome,LOL,office," ,freeTime:"周二1-2-3,周三3-4,周四7-8,"}];具體功能:
分別在兩個(gè)select選擇星期和課次，列表會(huì)即時(shí)根據(jù)條件更新。
