关于html动态添加radio的奇怪 *** 作?

关于html动态添加radio的奇怪 *** 作?,第1张

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!!!

复制过去就可以运行
