Is it possible to access a javascript variable when calling a js function from HTML?
I am trying to convert a Java program to HTML and JS and in Java code I am calling a method using an int from this class. Is this possible with HTML and JS? Can I write onload="myFunc(i + 1)"
or something like that?
If you need it, the Java code looks like this:
public int i = 0;
public String chooseACard(int j) {
if(j > cards.length - 1) j = 0;
return cards[j].front;
}
and it gets called:
ActionListener changeFrontListener = new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
if(e.getSource() == nextCard) {
textBox.setText(vc.chooseACard(vc.i + 1));
if(vc.i + 1 > vc.cards.length - 1) vc.i = 0;
else vc.i++;
}
}
};
Can I do something like this in HTML and JavaScript?

Yes, you can do it as shown below. Basically, you can assign a function name or a function expression to an event handler.
var i = 9;
function myFunc(t){
console.log(t);}
<button id="button1" onclick="myFunc(i + 1);">TestMe</button>
