Pass parameters in setInterval function

You need to create an anonymous function so the actual function isn't executed right away.

setInterval( function() { funca(10,3); }, 500 );

javascript parameters setinterval

now with ES5, bind method Function prototype :

setInterval(funca.bind(null,10,3),500);

javascript parameters setinterval

Add them as parameters to setInterval:

setInterval(funca, 500, 10, 3);

The syntax in your question uses eval, which is not recommended practice.
