Question

我是jquery的新手，想要从星期一开始打印所有时间（或者今天晚上==）

我设法打印对象的所有时间而不是我选择的一天，也许我的迭代是错误的，想要任何提示。

var arr = [{
  "dateString": "2016-12-05",
  "weekday": "mon",
  "opening_hours": [{
    "from": "09:00",
    "to": "15:00",
    "fromNumber": 9,
    "toNumber": 15
  }, {
    "from": "17:00",
    "to": "20:00",
    "fromNumber": 17,
    "toNumber": 20
  }]
}, {
  "dateString": "2016-12-06",
  "weekday": "tue",
  "opening_hours": [{
    "from": "09:00",
    "to": "17:00",
    "fromNumber": 9,
    "toNumber": 17
  }]
}, {
  "dateString": "2016-12-07",
  "weekday": "wed",
  "opening_hours": [{
    "from": "09:00",
    "to": "20:00",
    "fromNumber": 9,
    "toNumber": 20
  }]
}, {
  "dateString": "2016-12-08",
  "weekday": "thu",
  "opening_hours": [{
    "from": "1:00",
    "to": "11:00",
    "fromNumber": 1,
    "toNumber": 11
  }]
}];

$("button").click(function() {

  var today = new Date();
  var str = today.toString('dddd, MMMM ,yyyy')
  var sta = str.substring(0, 4);
  console.log(sta);
  $.each(arr, function(i, currProgram) {
    $.each(currProgram.opening_hours, function(key, val) {
      //    $.each(num, function (axa, dasa) {
      if (currProgram.weekday == "mon") {
        console.log("monday");
        timefrom = (val.from);
        timeto = (val.to);
      } else {
        console.log("no monday");
      }
      // console.log(num[axa]);
      $(".result").append("\ntime: " + timefrom + " to " + timeto + "\n");
      console.log("time: " + timefrom + " to " + timeto + "\n");
      //    });
    });
  });
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<p class="calnote">

结果应仅打印：

时间：09：00至15:00

时间：17：00至20:00

您可能希望将逻辑console.log("time: " + timefrom + " to " + timeto + "\n");移动到if块

var arr = [{
  "dateString": "2016-12-05",
  "weekday": "mon",
  "opening_hours": [{
    "from": "09:00",
    "to": "15:00",
    "fromNumber": 9,
    "toNumber": 15
  }, {
    "from": "17:00",
    "to": "20:00",
    "fromNumber": 17,
    "toNumber": 20
  }]
}, {
  "dateString": "2016-12-06",
  "weekday": "tue",
  "opening_hours": [{
    "from": "09:00",
    "to": "17:00",
    "fromNumber": 9,
    "toNumber": 17
  }]
}, {
  "dateString": "2016-12-07",
  "weekday": "wed",
  "opening_hours": [{
    "from": "09:00",
    "to": "20:00",
    "fromNumber": 9,
    "toNumber": 20
  }]
}, {
  "dateString": "2016-12-08",
  "weekday": "thu",
  "opening_hours": [{
    "from": "1:00",
    "to": "11:00",
    "fromNumber": 1,
    "toNumber": 11
  }]
}];

function buttonClick() {

  var today = new Date();
  var str = today.toString('dddd, MMMM ,yyyy')
  var sta = str.substring(0, 4); 
  $.each(arr, function(i, currProgram) {
    $.each(currProgram.opening_hours, function(key, val) {      
      if (currProgram.weekday == "mon") {
        //console.log("monday");
        timefrom = (val.from);
        timeto = (val.to);       
      	console.log("time: " + timefrom + " to " + timeto + "\n");      
      } else {
        //console.log("no monday");
      }      
    });
  });
}

buttonClick()
