我通过更改 num rooms 输入的值来创建一些输入。我想将 counter 的值替换为 span 中的特定值。例如下面的代码:
for (var i =1; i <= $num; i++){
"<span class=' btn-block room-name'>Room" + i +"</span>"
}
如果 i=1 ， 1 替换为跨度中的第一个，结果:房间第一个。 i=2 房间第二等。
<div class="form-group col-sm-4">
<input type="number" class="form-control numRoom-btn" placeholder="num rooms" min="1" max="5" />
</div>
<div id="room-container"> </div>
$(document).ready(function () {
$(".numRoom-btn").change(function () {
switch (this.value) {
case "1":
clearBefore();
addRoom("1");
break;
case "2":
clearBefore();
addRoom("2");
break;
case "3":
clearBefore();
addRoom("3");
break;
case "4":
clearBefore();
addRoom("4");
break;
case "5":
clearBefore();
addRoom("5");
break;
}
});
function addRoom($num) {
for (var i =1; i <= $num; i++) {
var $addedElement = $(
"<div class='numRoom calendar-container'>"+
"<span class=' btn-block room-name'>Room" + i +"</span>" +
"<div class='form-group col-sm-4'>"+
"<span class='btn-block mb5'> Adult(+12)</span>"+
"<input type='number' class='form-control' placeholder='adult nums' min='1' max='9' />"+
"</div>"+
"<div class='form-group col-sm-4'>"+
"<span class='btn-block mb5'>child(-11)</span>"+
"<input type='number' class='form-control' placeholder='child nums' min='0' max='6' />"+
"</div>"+
"</div>");
$('#room-container').append($addedElement);
}
}
function clearBefore() {
$('.numRoom').remove();
}
});
