推荐答案

您的可能的做用下面的jQuery的：

You could do that with the following jQuery:

$(function(){
  $("select[name='listServiceTypes']").removeAttr('multiple');
});

不过，这将是更好的在服务器端做。而不是使用 Html.ListBox ，这将是更好地使用 Html.DropDownList ：

<%=Html.DropDownList("listServiceTypes", 
                Model.ServiceTypeListAll, 
                new { style = "width: 500px;height:200px", size=4 }); %>

此不必做任何的jQuery / JavaScript作为它产生pretty大致相同的HTML删除多个属性，但没有<$ C不再需要$ C>多个属性。具有尺寸大于1告诉来显示它作为一个多行列表框中浏览器的值。

This removes the need from having to do any jQuery/JavaScript to remove the multiple attribute as it produces pretty much the same HTML but without the multiple attribute. Having a value for size that is greater than 1 tells the browser to display it as a multi-line list box.
