使用createElement动态创建HTML对象

<script language="javascript">
var o = document.body;
//创建链接
function createA(url,text)
{
	var a = document.createElement("a");
	a.href = url;
	a.innerHTML = text;
	a.style.color = "red";
	o.appendChild(a);
}
createA("http://www.mzwu.com/","木子屋");
</script>

<script language="javascript">
var o = document.body;
//创建DIV
function createDIV(text)
{
	var div = document.createElement("div");
	div.innerHTML = text;
	o.appendChild(div);
}
createDIV("木子屋：http://www.mzwu.com/");
</script>

<script language="javascript">
var o = document.body;
//创建表单项
function createInput(sType,sValue)
{
	var input = document.createElement("input");
	input.type = sType;
	input.value = sValue;
	o.appendChild(input);
}
createInput("button","ooo");
</script>

<script language="javascript">
var o = document.body;
//创建表格
function createTable(w,h,r,c)
{
	var table = document.createElement("table");
	var tbody = document.createElement("tbody");
	table.width = w;
	table.height = h;
	table.border = 1;
	for(var i=1;i<=r;i++)
	{
		var tr = document.createElement("tr");
		for(var j=1;j<=c;j++)
		{
			var td = document.createElement("td");
			td.innerHTML = i + "" + j;
			//td.appendChild(document.createTextNode(i + "" + j));
			td.style.color = "#FF0000";
			tr.appendChild(td);
		}
		tbody.appendChild(tr);
	}
	table.appendChild(tbody);
	o.appendChild(table);
}
createTable(270,270,9,9);
</script>
