该Function()构造函数需要任意数量的字符串参数。最后一个参数是函数的主体-它可以包含任意JavaScript语句，以分号分隔。
您可以尝试运行以下代码以使用新的Function Constructor调用函数-
<html>
<head>
<script>
var func = new Function("x", "y", "return x*y;");
function multiplyFunction(){
var result;
result = func(15,35);
document.write ( result );
}
</script>
</head>
<body>
<p>Click the following button to call the function</p>
<form>
<input type = "button" onclick = "multiplyFunction()" value = "Call Function">
</form>
</body>
</html>
