【问题描述】：
我想使用下拉和 jquery 更改要显示的表单，但似乎不起作用。我确实尝试了一个仅使用几个 div 和一个段落的简单代码，并且我认为它起作用了，因为当我将表单放入其中时它不再起作用。 顺便说一下，这是我的代码：
//this is the form
<div class="container">
<h3>Choose the brand you want to input</h3> <br>
<select id="brand-combox" class="custom-select col-sm-2" name="brand-combox">
<option selected value="#">Select a Brand</option>
<option value="qnap">Qnap</option>
<option value="asustor">Asustor</option>
<option value="nutanix">Nutanix</option>
<option value="dji">DJI</option>
<option value="wps">WPS Office</option>
</select>

这里是 jquery：
$('#brand-combox').on('change', function(){
if (this.value == 'qnap') {
$('#qnap-form').show();
$('#asustor-form').hide();
}
else if(this.value == 'asustor'{
$('#qnap-form').hide();
$('#asustor-form').show();
}
});
我也尝试了任何不同的方法，但我仍然无法找出我错过了什么。 你会这么好心来帮助我吗？
