我有预订表格。如果我的一个客户遇到问题,我希望他们在他们喜欢的时间给我打电话。为此,我创建了两个下拉列表框。第一个组合框应包含两个选项(如代码段中所示),默认情况下选择立即调用。如果选择第二个选项立即呼叫,则第二个下拉列表应填充可用的时间段,如:
12:00
13:00
16:00
20:00
...
...
等等。怎么可以实现呢?
$("#call-day").change(function(e){
val=$("option:selected",this).val();
if(val=="today"){
}else if(val=="tomorrow"){
}
});
<select name="call-day" id="when-ajax">
<option class="today">Call Today</option>
<option class="tomorrow">Call Tomorrow</option>
</select>
<select name="hours">
<option>Call Now</option>
</select>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

你的问题太模糊了。请改写它。根据我的描述,您的描述可以帮助您实现您的目标。请注意,我冒昧地承担了某些事实。
$("select[name='call-day']").change(function(e){
val=$(this).val();
if(val=="today"){
//What you want to do here is not mentioned. So I am leaving it blank
}else if(val=="tomorrow"){
//Available time slots should be retrieved from some persistent location. Assuming it is already done...
var availableSlots = ["12:00", "13:00", "14:00", "16:00"];
$("select[name='hours']").empty();
$("select[name='hours']").append("<option value=''>--Select Time--</option");
for(i in availableSlots){
var item = availableSlots[i];
var optionElement = "<option value='"+ item +"'>" + item + "</option>";
$("select[name='hours']").append(optionElement);
}
}
});

<select name="call-day" id="when-ajax">
<option value="today">Call Today</option>
<option value="tomorrow">Call Tomorrow</option>
</select>
<select name="hours">
<option>Call Now</option>
</select>
