I have the following code snippet embedded into some of my divs so when those divs get clicked a certain radio button gets checked.

onclick="document.g1.city[0].checked=true;"

However I would like to convert the above call to a function call like below:

onclick="checkRadioButton(city[0]);"

And the function will be something like this

function checkRadioButton(input){
    document.g1.input.checked=true;
}

Is there a way I can accomplish this?
