动态数据存数据
<script>
function creatSel(){
var v1=document.getElementById( "sel ").value;
var sel=document.createElement( "select ");
var item = new Option( "+ "+v1, "+ "+v1);
var item1 = new Option( "- "+v1, "- "+v1);
sel.options.add(item);
sel.options.add(item1);
//document.write
document.body.appendChild(sel);
}
</script>
</head>
<body>
<select id= "sel " onchange= "creatSel() " name= "sel ">
<option value= "1 "> v1 </option>
<option value= "2 "> v2 </option>
<option value= "3 "> v3 </option>
<option value= "4 "> v4 </option>
</select>
我想用动态数据保存每次 NEW出来的SEL里的值 可不知道怎么写,麻烦大家了
