javascript怎么给元素节点增加属性

<script language="javascript" type="text/javascript">

function fcreatenode()

{

var op=document.createElement("div")

//var oa=document.createAttribute("style")

//op.attributes.setNamedItem(oa)

//op.setAttribute("style","color:#555555")

op.style.color = "#555555" //style 是一个已存在的属性

//var otext=document.createTextNode("hello world")

//op.appendChild(otext)

op.innerHTML = "hello world"

document.getElementById("div1").appendChild(op)

}

</script>

参考如下：

//把数据写入数据库

function res() {

//获取输入值(myname和mymail是两个文本框的id)

var uname = document.getElementById("myname").value

var umail = document.getElementById("mymail").value

//数据库连接对象

var con = new ActiveXObject("ADODB.Connection")

//连接字符串

var str = "DRIVER={SQL SERVER}SERVER=(local)uid=sapwd=123456database=xslt"

//打开数据源

con.Open(str)

//sql语句

var sql = "insert into xslt(name,mail) values(''" + uname + "'',''" + umail + "'')"

try {

//执行sql语句

con.Execute(sql)

//关闭连接

con.Close()

//转向成功页面

window.location.href = "/uploadfile/201101/18/AF93632542.gif" />}

catch (e) {

alert(e)

}

}
