我正在制作一个网站，目前我希望能够执行以下操作:
如果用户在国家/地区选择器中选择“美国”。
然后 (field9[state]) 成为具有美国各州名称的选择表单
否则，如果用户从国家/地区选择器中选择任何其他国家/地区
然后(field9[state] 保持为文本框 [input=text]，用户可以输入他们的状态)
这可能吗？如果是，我将如何执行这个...
谢谢大家。
这是我目前针对国家/地区和州的代码:

最佳答案
一种方法是将事件与您的国家/地区下拉列表相关联，然后，如果选择了美国，则显示州/省/自治区下拉列表并隐藏文本输入。如果未选择“美国”，则隐藏州下拉列表并显示文本输入。
我正在使用您的代码的简化版本。
HTML:
<select id="ddlCountry">
<option value="-1">-- SELECT --</option>
<option value="0">US</option>
<option value="1">Other</option>
</select>
<br />
<input type="text" id="txtState" value="" placeholder="state">
<select id="ddlState" class="hidden">
<option value="Alabama">Alabama</option>
<option value="Alaska">Alaska</option>
</select>
JQuery:
$('#ddlCountry').change(function () {
if ($(this).val() == "0") {
$('#ddlState').removeClass('hidden');
$('#txtState').addClass('hidden');
} else {
$('#ddlState').addClass('hidden');
$('#txtState').removeClass('hidden');
}
});
CSS:
.hidden {
display: none;
}
关于javascript - HTML/PHP/JQUERY - 选择正确的国家/地区时，将表单中的文本输入类型字段更改为选择器字段，否则将字段保留为文本框输入，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/33703053/
