JavaScript Event Handler Arguments

I have the following JavaScript code: var ans_el = document.createElement( 'input' ); ans_el.setAttribute( 'id', unique_int_value ); ans_el.setAttribute( 'type', 'radio' ); ans_el.

Solution 1:

You need to give a reference to a function for onclick; you are currently executing the function and assigning that result to the onclick handler. This is closer to what you want:

ans_el.onclick = function(e) {
   myFunction(ans_el.id, ans_el.value);
};

UPDATED: Decided to use event.target for a clearer example since Andir brought it up.

ans_el.onclick = function(e) {
   myFunction(e.target.id, e.target.value);
};
