find which object called function
0
If I have multiple objects with different IDs but they all call the same function when clicked. Is there any way to track or find which object called the function.
e.g
function test(){
/*function changes background color of 'div' and displays the id of the object that called the function*/
document.getElementById('div').style.backgroundColor = 'red';
var objectID = /*WHATEVER OBJECT CALLED FUNCTION*/;
document.getElementById('textbox').innerHTML = objectID;
}
cheers

of course, depending on how test is called, it could be simpler, but you haven't shown that very important piece of the puzzle :p

If you're using
onclick="test()"
in the element, change it so that it passes itself to the function:
onclick="test(this)"
Then the function receives the object as the argument.
function test(element) {
var objectID = element.id;
...
}

Just do this:
function test(id) {
document.getElementById('div').style.backgroundColor = 'red';
var objectID = id;
document.getElementById('textbox').innerHTML = objectID;
}
var object = {
id = "AnObject",
testFunction: function() {
test(this.id);
}
};
object.testFunction();
