我有wp主题，我正在修改以添加儿童年龄，每个房间都有成人，儿童和孩子年龄 screenshot
下面的代码是获取有多少房间的表格＆amp;显示每个房间的每种输入类型
<tbody>
<?php foreach ( $room_ids as $room_id => $available_rooms ) :
$max_adults = get_post_meta( $room_id, '_room_max_adults', true );
$max_kids = get_post_meta( $room_id, '_room_max_kids', true );
if ( empty( $max_adults ) || ! is_numeric( $max_adults ) ) $max_adults = 0;
if ( empty( $max_kids ) || ! is_numeric( $max_kids ) ) $max_kids = 0;
?>

我试图添加的是如何显示/隐藏孩子年龄的一种方式，这取决于我有多少孩子这个javascript
$('.room-kids').change(function(){
var $quantity = $(this).closest('tr').find('.room-quantity');
var kids = parseInt($(this).val(),10);
var max_kids = 0;
if ( $(this).parent('.numbers-row').attr('data-per-room') ) {
if (kids >= 1) {
$("#kid1").show("fast");
}else{
$("#kid1").hide("fast");
}
if (kids >= 2) {
$("#kid2").show("fast");
}else{
$("#kid2").hide("fast");
}
if (kids >= 3) {
$("#kid3").show("fast");
}else{
$("#kid3").hide("fast");
}
if (kids >= 4) {
$("#kid4").show("fast");
}else{
$("#kid4").hide("fast");
}
max_kids = $(this).parent('.numbers-row').data('per-room');
if ( ( max_kids * $quantity.val() < kids ) ) $quantity.val( Math.ceil(kids / max_kids) );
}
});
我的问题是，当我改变任何其他行上的孩子时，它会影响第一行的孩子年龄而不是它自己的行
答案 0 :(得分：0)
$('.room-kids').change(function(){
var $quantity = $(this).closest('tr').find('.room-quantity');
var kids = parseInt($(this).val(),10);
var max_kids = 0;
if ( $(this).parent('.numbers-row').attr('data-per-room') ) {
if (kids == 1) {
$("#kid1").show("fast");
}else{
$("#kid1").hide("fast");
}
if (kids == 2) {
$("#kid2").show("fast");
}else{
$("#kid2").hide("fast");
}
if (kids == 3) {
$("#kid3").show("fast");
}else{
$("#kid3").hide("fast");
}
if (kids == 4) {
$("#kid4").show("fast");
}else{
$("#kid4").hide("fast");
}
max_kids = $(this).parent('.numbers-row').data('per-room');
if ( ( max_kids * $quantity.val() < kids ) ) $quantity.val( Math.ceil(kids / max_kids) );
}
});
