The JSP code runs on the server, and cannot run that sort of on-page JavaScript. By the time the processed page gets to the browser, there's no trace left of the JSP.

Invoking a JavaScript Function The code inside a function is not executed when the function is defined. The code inside a function is executed when the function is invoked. It is common to use the term " call a function " instead of " invoke a function ". A JavaScript function can have an optional return statement. This is required if you want to return a value from a function. This statement should be the last statement in a function. For example, you can pass two numbers in a function and then you can expect the function to return their multiplication in your calling program. JavaScript provides 8 mathematical constants that can be accessed as Math properties: Example. Math.E // returns Euler's number. Math.PI // returns PI. Math.SQRT2 // returns the square root of 2. Math.SQRT1_2 // returns the square root of 1/2. Math.LN2 // returns the natural logarithm of 2. Math.LN10 // returns the natural logarithm of 10.

A JavaScript function is a block of code designed to perform a particular task. A JavaScript function is executed when "something" invokes it (calls it). Example. function myFunction (p1, p2) {. return p1 * p2; // The function returns the product of p1 and p2. }

If we use to apply the validation we make use of JavaScript method in validation.jsp to validate the LoginName and password.
