您可以结合使用两个助手：
public static class HtmlExtensions
{
public static MvcHtmlString Script(this HtmlHelper htmlHelper, Func<object, HelperResult> template)
{
htmlHelper.ViewContext.HttpContext.Items["_script_" + Guid.NewGuid()] = template;
return MvcHtmlString.Empty;
}
public static IHtmlString RenderScripts(this HtmlHelper htmlHelper)
{
foreach (object key in htmlHelper.ViewContext.HttpContext.Items.Keys)
{
if (key.ToString().StartsWith("_script_"))
{
var template = htmlHelper.ViewContext.HttpContext.Items[key] as Func<object, HelperResult>;
if (template != null)
{
htmlHelper.ViewContext.Writer.Write(template(null));
}
}
}
return MvcHtmlString.Empty;
}
}
然后在您的_Layout.cshtml：
<body>
...
@Html.RenderScripts()
</body>
在某些模板中：
@Html.Script(
@<script src="@Url.Content("~/Scripts/jquery-1.4.4.min.js")" type="text/javascript"></script>
)
