I am basing my question and example on Jason's answer in this question(我将我的问题和示例基于Jason在此问题中的回答)
I am trying to avoid using an eventListener , and just to call handleClick onsubmit , when the submit button is clicked.(我试图避免使用eventListener ，而是在单击提交按钮时仅调用handleClick onsubmit 。)
Absolutely nothing happens with the code I have.(我拥有的代码绝对不会发生任何事情。)
Why is handleClick not being called?(为什么不调用handleClick ？)
<html>
<head>
<script type="text/javascript">
function getRadioButtonValue(rbutton)
{
for (var i = 0; i < rbutton.length; ++i)
{
if (rbutton[i].checked)
return rbutton[i].value;
}
return null;
}
function handleClick(event)
{
alert("Favorite weird creature: "+getRadioButtonValue(this["whichThing"]));
event.preventDefault(); // disable normal form submit behavior
return false; // prevent further bubbling of event
}
</script>
</head>
<body>
<form name="myform" onSubmit="JavaScript:handleClick()">
<input name="Submit" type="submit" value="Update" onClick="JavaScript:handleClick()"/>
Which of the following do you like best?
<p><input type="radio" name="whichThing" value="slithy toves" />Slithy toves</p>
<p><input type="radio" name="whichThing" value="borogoves" />Borogoves</p>
<p><input type="radio" name="whichThing" value="mome raths" />Mome raths</p>
</form>
</body>
</html>

Please do not suggest a framework as a solution.(请不要提出框架作为解决方案。)
Here are the relevant changes I have made to the code, which results in the same behavior.(这是我对代码进行的相关更改，导致相同的行为。)
function handleClick()
{
alert("Favorite weird creature: "+getRadioButtonValue(document.myform['whichThing'])));
event.preventDefault(); // disable normal form submit behavior
return false; // prevent further bubbling of event
}
</script>
</head>
<body>
<form name="aye">;
<input name="Submit" type="submit" value="Update" action="JavaScript:handleClick()"/>
