mvc 注册脚本的其他方法

privatestaticSortedList<int,string>GetRegisteredScriptIncludes()
{
    var registeredScriptIncludes =System.Web.HttpContext.Current.Items["RegisteredScriptIncludes"]asSortedList<int,string>;

    if(registeredScriptIncludes ==null)
    {
        registeredScriptIncludes =newSortedList<int,string>();
        System.Web.HttpContext.Current.Items["RegisteredScriptIncludes"]= registeredScriptIncludes;
    }

    return registeredScriptIncludes;
}

publicstaticvoidRegisterScriptInclude(thisHtmlHelper htmlhelper,string script)
{
    var registeredScriptIncludes =GetRegisteredScriptIncludes();
    if(!registeredScriptIncludes.ContainsValue(script))
    {
        registeredScriptIncludes.Add(registeredScriptIncludes.Count, script);
    }
}

publicstaticstringRenderScripts(thisHtmlHelper htmlhelper)
{
    var registeredScriptIncludes =GetRegisteredScriptIncludes();
    var scripts =newStringBuilder();
    foreach(string script in registeredScriptIncludes.Values)
    {
        scripts.AppendLine("<script src='"+ script +"' type='text/javascript'></script>");
    }
    return scripts.ToString();
}

然后

<%
    Html.RegisterScriptInclude(Url.Content("~/Scripts/my.js"));
%>

最后在body中相应的位置添加下面这句

<%=Html.RenderScripts() %>

///////////////////////////////////////////////

直接通过 javascript 来注册脚本

<scripttype="text/javascript"src="somescript.js"></script>

相当于

var script = document.createElement('script');
script.type ='text/javascript';
script.src ='somescript.js';
$('#someElement').append(script);
