Question

html 通过 js 动态添加div

Answer 1

var com = document.createElement("div");
document.getElementById("XXXX").appendChild(com);
com.x = x;
com.y = y;
com.style.left = "XXpx";
com.style.top = "YYpx";
var txt = document.createElement("input");
txt.nodeType = "text";
com.appendChild(txt);
var btn = document.createElement("input");
btn.nodeType = "button";
btn.onclick = ConfirmComment();
com.appendChild(btn);

Answer 2

向所有段落中追加一些HTML标记。

HTML 代码:
<p>I would like to say: </p>

jQuery 代码:
$("p").append("<b>Hello</b>");

结果:
[ <p>I would like to say: <b>Hello</b></p> ]
