Answer 1

function page(){
var f = document.getElementById("b");
var input = document.createElement("input");
var text = document.createTextNode("####");
input.setAttribute("type","hidden");
input.setAttribute("value","哈哈");
input.setAttribute("id","hidden");
f.appendChild(text);
f.appendChild(input);
alert(document.getElementById("hidden").value);
}
