这是我的第一篇文章，我有两个问题：

  1. 当我从上到下选择（回答）所有内容时，计算工作正常。如果我更改“日期”，它会重新计算，但是当我之后更改“box2”时，它不会重新计算。有解决办法吗？

  2. 因为这是我的第一个脚本，所以我想知道它是否有用？

    $(document).ready(function() {

$("#box").chained("#box2").change(function() {

var selector = function (dateStr) {
var d1 = $('#from').datepicker('getDate');
var d2 = $('#to').datepicker('getDate');
var diff = 0;

    if (d1 && d2) {
        diff = Math.floor((d2.getTime() - d1.getTime()) / 86400000); // ms per day
    }

    $('#days').val(diff);

var ttl = $('#totaal');
var discon = $('#discount-container');
var disc = $('#discount');
var tax = $('#tax');
var price = $('#box option:selected').attr('data-price');
var total = diff * price;
var tax7 = total*0.07;
var disc75 = total*0.075;
var disc15 = total*0.15;


if (diff >7 && diff <15) {
    discon.show('slow');
    disc.val("- " + disc75.toFixed(2));
    tax.val("+ "+ tax7.toFixed(2));
    ttl.val("Naf. "+  (total+tax7).toFixed(2));
} 
else if (diff >14 ) {
    discon.show('slow');
    disc.val("- " + disc15.toFixed(2));
    tax.val("+ "+ tax7.toFixed(2));
    ttl.val("Naf. "+  (total+tax7).toFixed(2));
} 
else {
    discon.hide('slow');
    tax.val("Naf. "+ tax7.toFixed(2));
    ttl.val("Naf. "+  (total+tax7).toFixed(2));
}
 }  

    $('#from').datepicker({
    dateFormat: 'D dd-mm-yy', 
    minDate: '+1D',
    maxDate: '+2Y',
    changeMonth: true,
    numberOfMonths: 1,
    onClose: function( selectedDate ) {
    $( "#to" ).datepicker( "option", "minDate", selectedDate );
    }
});
$('#to').datepicker({
    dateFormat: 'D dd-mm-yy', 
    minDate: '+1D',
    maxDate: '+2Y',
    changeMonth: true,
    numberOfMonths: 1,
    onClose: function( selectedDate ) {
    $('#from').datepicker( "option", "maxDate", selectedDate );
    }
});

$('#from,#to').change(selector)


});

});

1.

长$("#box").chained("#box2").change(function() {
到 $("#box, #box2").change(function() {

2. 您的代码看起来不错，但是因为您没有很多元素实例，我建议您放弃将每个选择器定义为变量。
