Calling a function using a string: JavaScript
In JavaScript it is possible to call a function using a string. All you need to know is the object the function resides in and the name of the function as a string.
You could do this using eval(), but apparently it is a big ‘no-no’ for security reasons. Here is a safer approach:
function dave(message) {
alert(message);
}
// object[functionString](args)
window['dave']('hello');Clean and simple, without opening eval(“Pandora’s Box”).
