我有一个包含2个单选按钮的表单。并且，在表单的底部是＆＃34;提交＆＃34;按钮。
一键是选择Paypal作为付款方式;另一个按钮是选择信用卡。
我写了一个脚本来＆＃34;禁用＆＃34;提交，除非选择了其中一个单选按钮。
出于某种原因，我的＆＃34;提交＆＃34;按钮仍然已禁用。 （（
这是我的剧本：
<script
src='http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js'>
</script>
<script type='text/javascript'>
function displayForm(c) {
if (c.value == "2") {
jQuery('#paypalformContainer').toggle('show');
jQuery('#ccformContainer').hide();
if(document.getElementById('radio2').checked==true)
{
document.getElementById('radio1').checked=false;
}
}
if (c.value == "1") {
if(document.getElementById('radio1').checked==true)
{
document.getElementById('radio2').checked=false;
}
jQuery('#ccformContainer').toggle('show');
jQuery('#paypalformContainer').hide();
}
};
</script>
<script type="text/javascript">
function fCheck() {
var x = document.getElementById('radio1').value;
var x2 = document.getElementById('radio2').value;
if (x==null || x=="") {
document.getElementById('submit').disabled=true;
} else { if (x2==null || x2=="") {
document.getElementById('submit').disabled=true; } else {
document.getElementById('submit').disabled=false; } } }
</script>
这是形式本身：
