在dropDownList中实现既能输入一个新值又能实现下拉选的代码

复制代码 代码如下:

<div><%--left:279px; top:167px"--%>
<asp:DropDownList runat="server" ></asp:DropDownList>
</div>
<asp:TextBox runat="server" Font-Size="10" MaxLength ="50"></asp:TextBox>
<script>
function addTxtTanto(va)
{
document.getElementById("workerno_value").value=va;
document.getElementById("workerno_value").select();
}
</script>

复制代码 代码如下:

page_load()
{
if (!IsPostBack)
{
workerno_list.Attributes["onchange"] = "addTxtTanto(this.options[selectedIndex].innerText)";
}
}
