Well, you can add any legal JavaScript statement including this:
好吧，您可以添加任何合法的 JavaScript 语句，包括：
<form onsubmit="return verify1() && verify2()">
or this
或这个
<form onsubmit="return verify1() || verify2()">
or more complex expressions which can include multiple function calls. Note that standard evaluation rules apply including short-circuit evaluation of logical expressions.
或更复杂的表达式，其中可以包含多个函数调用。请注意，标准评估规则适用，包括逻辑表达式的短路评估。

I believe that wouldn't work. You should just make a wrapper function, and include the functions which you desire to execute, inside of that.
我相信那是行不通的。您应该只制作一个包装函数，并在其中包含您希望执行的函数。
<script type="text/javascript">
var run1 = function() { alert("first"); }
var run2 = function() { alert("second"); }
function sub() {
run1();
run2();
}
</script>
<form name="form" method="POST" action="contactus.asp" onsubmit="javascript:sub();">
