How to invoke a JavaScript Function with 'new' Function Constructor?
The Function() constructor expects any number of string arguments. The last argument is the body of the function - it can contain arbitrary JavaScript statements, separated from each other by semicolons.
Example
You can try to run the following code to invoke a function with new Function Constructor −
<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>
