This is the code in my index.html in eclipse. However, when you click the Click button, nothing happens. What could be the disadvantage?

This is the code in my index.html

file in Eclipse. Part javascript

doesn't work.

When I click the "Click" button, the function send()

fails. no warning window is displayed.

Even if I do <button onClick="alert('heloo')">Click</button>

, no warning appears.
