jquery json select

jquery 得到json 的值了

e =[{"pId":"1","sName":"长沙"},{"pId":"2","sName":"娄底"},{"pId":"3","sName":"邵阳"}]已经得到json的值了  
}
怎么把 1 长沙 对应 放在select option下的 name value 下呢

HTML code

<select id="select">

</select>
<script>
e =[{"pId":"1","sName":"长沙"},{"pId":"2","sName":"娄底"},{"pId":"3","sName":"邵阳"}]  
var s = document.getElementById("select")
for(var i = 0 ; i < e.length ; i++)
{
   var op = new Option(e[i].sName,e[i].pId);
   s.appendChild(op)  
}
</script>

上面那个好像不兼容IE,试试这个
HTML code

<select id="select">

</select>
<script>
e =[{"pId":"1","sName":"长沙"},{"pId":"2","sName":"娄底"},{"pId":"3","sName":"邵阳"}]

for(var i = 0 ; i < e.length ; i++)
{
   var op = document.createElement("option");
   op.value = e[i].pId;
   op.innerHTML = e[i].sName
   s.appendChild(op)
