Javascript 当对象具有相同的相同值时，数组不推送

Question

对象忽略具有相同值的其他数组。例如

data[2018][2][25] <-- this ones gets ignored to the object
data[2018][2][22]

代码：

var date = new Date();
var data = {};
<?php $eventsNum = 3>

<?php for ($r =1; $r <= 3; $r++):?>

    data[<?php echo $calendarYear[$r]?>] = {};
    <?php for ($s =1; $s <= 3; $s++):?>
        data[<?php echo $calendarYear[$r]?>][<?php echo $calendarMonth[$s]?>] = {};
        <?php for ($t =1; $t <= 2; $t++):?>
            data[<?php echo $calendarYear[$r]?>][<?php echo $calendarMonth[$s]?>][<?php echo $calendarDay[$s] ?>] = {};
            //$num =  $calendarDay[$s];
            try {
              data[<?php echo $calendarYear[$r]?>][<?php echo $calendarMonth[$s]?>][<?php echo $calendarDay[$s] ?>].push({
                    startTime: "<?php echo $calendarStart_time[1]?>",
                    endTime: "<?php echo $calendarEnd_time[1] ?>",
                    text: "<?php echo $calendar_description[1] ?>"

Answer 1

问题在于，每次通过循环，您都会完全替换属性中的现有对象。变化：

data[<?php echo $calendarYear[$r]?>] = {};

至：

if (!data[<?php echo $calendarYear[$r]?>]) {
    data[<?php echo $calendarYear[$r]?>] = {};
}

所有其他初始化也类似。
