如题所述
可以使用javascript动态生成option标签：
<html><body >
<select id="select1"></select>
<script>
var objSelectNow=document.getElementById("select1");
var inner="<option value='1'>1</option>";
objSelectNow.innerHTML=inner;
var objOption = document.createElement("OPTION");
objOption.text= 2;
objOption.value=2;
objSelectNow.options.add(objOption);
</script>
</body>
</html>

jquery 的话这样
<select id="selectid">
</select>
$(function(){
$("#selectid").click(function(){
$("#selectid").append("<option value='"+entity+"'>"+entity+"</option>");//entity 变量
});
});
js的话
楼上方法就行，已验证
function padd(){
var objOption = document.createElement("OPTION");
objOption.text= 2;
objOption.value=2;
document.getElementById("padd").options.add(objOption);
}
<select id="selectid">
</select>
$(function(){
$("#selectid").click(function(){
$("#selectid").append("<option value='"+entity+"'>"+entity+"</option>");//entity 变量
});
});
