这里理解不了,有谁能帮忙解释下吗?
function checkone(){
var j=document.getElementById("wb").value;
var hobby = document.getElementById("hobby"+j);
hobby.checked = true; } function checkone(){
var j=document.getElementById("wb").value;
var hobby = document.getElementById("hobby"+j);
hobby.checked = true; }2020-04-20
