Answer 1

使用this将当前对象传递给函数myFunction

Live Demo

<input id="price-postfix1" onclick="myFunction(this)" name="price-postfix" type="radio" value="$option1"/>Option1<br>
<input id="price-postfix2" onclick="myFunction(this)" name="price-postfix" type="radio" value="$option2"/>Option1<br>
<input id="price-postfix3" onclick="myFunction(this)" name="price-postfix" type="radio" value="$option3"/>Option1<br>

function myFunction(obj){
    document.getElementById('price-postfix').value = obj.value;
}
