ラジオボタンにhttp://www.somacon.com/p143.php javascript を使用して、選択されているラジオボタンに応じて送信 onclick location.href を変更しています。しかし、ボタンが適切に機能していないため、構文に問題がある可能性があると思います(ラジオボタンから適切に値を取得しているとは思いません)。ありがとうございます!
コードは次のとおりです。
<head>
<script type="text/javascript">
<!--
// return the value of the radio button that is checked
// return an empty string if none are checked, or
// there are no radio buttons
function getCheckedValue(radioObj) {
if(!radioObj)
return "";
var radioLength = radioObj.length;
if(radioLength == undefined)
if(radioObj.checked)
return radioObj.value;
else
return "";
for(var i = 0; i < radioLength; i++) {
if(radioObj[i].checked) {
return radioObj[i].value;
}
}
return "";
}
// set the radio button with the given value as being checked
// do nothing if there are no radio buttons
// if the given value does not exist, all the radio buttons
// are reset to unchecked
function setCheckedValue(radioObj, newValue) {
if(!radioObj)
return;
var radioLength = radioObj.length;
if(radioLength == undefined) {
radioObj.checked = (radioObj.value == newValue.toString());
return;
}
for(var i = 0; i < radioLength; i++) {
radioObj[i].checked = false;
if(radioObj[i].value == newValue.toString()) {
radioObj[i].checked = true;
}
}
}
