innerText是把对象内的所有内容都替换为文本，所以如果先添加radio，然后再用innerText，radio就会自然消失，被文本取代。
应该用appendChild的方式来添加文本，即：
var label = document.createElement("label")
var radio = document.createElement("input")
radio.type = "radio"
radio.name = "radio"// 名字随意
label.appendChild(radio)
var txt = document.createTextNode("一个radio")
label.appendChild(txt)
document.getElementById("Div").appendChild(label)// Div为父容器id
最后补充说一句：innerHTML和innerText 跟 appendChild 是两种不同的机制，最好不要混用！！！
