javascript - 单击“单选”时动态显示 DIV

Question

我收到了这段代码，但我似乎无法正常工作，我查看了之前的问题，但找不到任何与之完全相同的代码。也许这完全是错误的，应该重新开始？

我想要做的是在选择单选按钮时显示一个 div。这是我的代码:

<script type="text/javascript">
jQuery(document).ready(function($){
$('input[name="item_meta[478]"]').change(function(){
var val1 = $("input[name='item_meta[478]']:checked").val();
if (val1== "España") {
document.getElementById("div1").style.display = "block";
document.getElementById("div2").style.display = "none";
}
if (val1== "Intracomunitario") {
document.getElementById("div2").style.display = "block";
document.getElementById("div1").style.display = "none";
}
}
</script>

<form>
Show form?
<input type="radio" onclick="frmCheckDependent(this.value,'478')" checked="checked" value="España" id="field_478-0" name="item_meta[478]">España
<input id="field_478-1" type="radio" onclick="frmCheckDependent(this.value,'478')" value="Intracomunitario" name="item_meta[478]">Intracomunitario
</form>

<div id="div1" style="display:none">
Custom form España
</div>
<div id="div2" style="display:none">
Custom form Intracomunitario
</div>

非常感谢!

一位程序员告诉我我可以做我想做的事:

<script type="text/javascript">
jQuery(document).ready(function($){
$('input[name="item_meta[988]"], input[name="item_meta[989]"]').change(function(){
var val1 = $("input[name='item_meta[988]']:checked").val();
var val2 = $("input[name='item_meta[989]']:checked").val(); 
if (val1 !=undefined && val2 != undefined)
{$("#field_keytotal").val(val1+' '+val2);}
});
});
</script>

还有:

<form>
Show form? 
<input type="radio" id="showform" value="yes" name="showform" onchange="showhideForm(this.value);"/>Yes
<input type="radio" id="showform" value="no" name="showform" onchange="showhideForm(this.value);"/>No
</form>

<script type="text/javascript">
function showhideForm(showform) {
    if (showform == "yes") {
        document.getElementById("div1").style.display = 'block';
        document.getElementById("div2").style.display = 'none';
    } 
    if (showform == "no") {
        document.getElementById("div2").style.display = 'block';
        document.getElementById("div1").style.display = 'none';
    }
}
</script>

<div id="div1" style="display:none">
[formidable id=18]
</div>
<div id="div2" style="display:none">
You are not qualified to see this form.
</div>

您缺少一个右括号。在</script>前加一
