我正在使用Mobiscroll Jquery demo，并试图获得在console.log中显示的aria-label的值。目前，每次单击日期时，我都会得到null。有人能帮我解决这个问题吗？

            <div id="demo"></div>

<script>
    
    mobiscroll.setOptions({
    locale: mobiscroll.localeEn,  // Specify language like: locale: mobiscroll.localePl or omit setting to use default
    theme: 'ios',                 // Specify theme like: theme: 'ios' or omit setting to use default
        themeVariant: 'light'     // More info about themeVariant: https://docs.mobiscroll.com/5-20-0/calendar#opt-themeVariant
});

$(function () {
    // Mobiscroll Calendar initialization
    $('#demo').mobiscroll().datepicker({
        controls: ['calendar'],   // More info about controls: https://docs.mobiscroll.com/5-20-0/calendar#opt-controls
        display: 'inline'         // Specify display mode like: display: 'bottom' or omit setting to use default
    });
});

var inputs = document.querySelectorAll("[aria-label]");
console.log(inputs.length);
for(var i = 0; i < inputs.length; i++){
inputs[i].addEventListener("click", function(e){
    console.log(this.getAttribute("aria-label"));
});     
}
</script>
