hours, times兩個數組比對，后生成一個新的數組。希望得到:[{"date":"2017-08-30","hours":[{"hour":"08:00","state":true},{"hour":"08:30"}]},{"date":"2017-08-31","hours":[{"hour":"08:00"},{"hour":"08:30","state":true}]}]//目前代碼var hours = [{"hour":"08:00"},{"hour":"08:30"}];var time=[{ "date":"2017-08-30","time":"08:00"},{"date":"2017-08-31","time":"08:30"}]var newdata=[]times.forEach(function(e,i){    hours.forEach(function(a,j){      if(e.date==a.hour){        a.state=true      }    })    newdata.push({      date:e.date,      hours:hours    })})console.log(JSON.stringify(newdata))//輸出結果[{"date":"2017-08-30","hours":[{"hour":"08:00","state":true},{"hour":"08:30","state":true}]},{"date":"2017-08-31","hours":[{"hour":"08:00","state":true},{"hour":"08:30","state":true}]}]
