我的下面的代码显示了当从下拉菜单中选择匹配的国家时正确的城市/州div,但是如果用户决定选择另一个州,它不会隐藏前一个。我是否必须为每个想要隐藏的div创建一个if/else?多次显示/隐藏jquery
<script type="text/javascript">
$(document).ready(function() {
...
//city & state display
$("#ctry").change(function() {
$(".state").hide();
var stateSelect = $("#state_" + $(this).val());
if (stateSelect.length === 0)
$("#state_label").hide();
else {
$("#state_label").show();
stateSelect.show();
}
});
});
</script>
的html代码:
<label>Country/Locale:</label>
<select id="ctry" name="country">
<option value="">-- Select</option>
<option value="US">United States</option>
<option value="CA">Canada</option>
