function show_alert(a) {
alert(a);
}
Now, let's say we want to call this function when a user clicks a text in an
`fastn` component. Here's how we can achieve this in `index.ftd`:
-- ftd.text: Click here to print name in alert!
$on-click$: $call-js-fn(a = FifthTry Alert)
-- void call-js-fn(a):
string a:
js: functions.js
show_alert(a)
In the above example, when the user clicks the text component, the `call-js-fn`
function is called, passing the `FifthTry` value to the argument `a`. This
function, then, references `functions.js` by using the `js` attribute and calls
the `show_alert` function.
