这是我的HTML:

<div id="all-room-alert-msg" class="alert alert-success text-center"></div>
</div>
</div>
<div id="show-next-month-all" data-toggle="calendar"></div>
</div>
<script src="assets/web/assets/jquery/jquery.min.js"></script>
<!--<script type="text/javascript" src="assets/calendar/scripts/jquery.min.js"></script>-->
<script type="text/javascript" src="assets/calendar/scripts/dateTimePicker.js"></script>
<script type="text/javascript">
$(document).ready(function()
{
$('#show-next-month-all').calendar(
{
num_next_month: 2,
num_prev_month: 0,
adapter: 'assets/calendar/server/adapter.php',
onSelectDate: function(date, month, year)
{
// alert([year, month, date].join('-') + ' is: ' + this.isAvailable(date, month, year));
document.getElementById("all-room-alert").style.visibility = "visible";
if(this.isAvailable(date, month, year)) {
var price = this.getPrice(date, month, year);
console.log('success', price);
// alert(this.price);
document.getElementById("all-room-alert-msg").className = "alert alert-success text-center";
document.getElementById("all-room-alert-msg").innerText = [year, month, date].join('-') + ' is available and the price is ' + price;
} else {
document.getElementById("all-room-alert-msg").className = "alert alert-danger text-center";
document.getElementById("all-room-alert-msg").innerText = [year, month, date].join('-') + ' is not available';
}
}
});
</script>
php文件:(仅用于测试)
The php file : (just for test)
echo(json_encode(array("IDR2,670,000")));
现在，我得到的错误是价格未定义，但是当我查看控制台时，数据在那里，只是滞后了.
Now, the error that I got is price is undefined but when i look at the console, the data is there, just lagged behind.
当我尝试通过控制台输出时，成功"未定义，然后在该行下方，我从PHP文件中获得了成功1"和价格.
When i try to output through console, the 'success' got undefined then below that line, i got 'success 1' and the price from the PHP file.
发现了如何做.在DatePicker.js的几乎内部，我添加了一个名为getPrice()的新函数，它接受了日期，月份，年份，警报框ID的参数.调用getJson完成后，它将结果附加到警报框.
Found out how to do it. Pretty much inside DatePicker.js, I added a new function called getPrice() and it takes in parameters date, month, year, alert-box-id. After calling getJson is done, it will append the result to the alert box.
推荐答案
您可以使用json_encode((您的数组)，1)并检查价格值.
You can use json_encode((your array), 1) and check the value of price.
