如何在js中帮忙创建隐藏字段hidde

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)

}

document.getElementById(id).style.display="block"显示

document.getElementById(id).style.display="none"隐藏

jquery js:

$("#"+id).show()//显示

$("#"+id).hide()//隐藏
