推荐答案

编写一个JavaScript函数，该函数将DropDownList的宽度设置为所需的宽度，并调用DropDownList的该函数onfocus >.

就像这样:

Write a JavaScript function which sets the width of the DropDownList to the required width and call this function onfocus of the DropDownList.

So something like:

<asp:DropDownList ID="DropDownList1" runat="server" Width="60px" onfocus="javascript:changeWidth();">
</asp:DropDownList>

Javascript:

Javascript:

function changeWidth()
    {
        document.getElementById("DropDownList1").style.width = "150px";
    }
