Question

I have an HTML form with multiple text inputs. I want to clear the element that had the focus immediately prior to when the \'Clear\' button is pressed. How do I ge

Answer 1

Create a global variable for storing the current focused element's id,

var cur_id;

call one function for onblur of each of elements and pass id

and write the set the id to global variable from that function

function setId(id) {
    cur_id = id;
}

and write a function for onclick of clear button, like this

function clear() {
    document.getElementById(cur_id).value = "";
}
