以编程方式将样式表和 javascript 引用添加到 ASP.NET 母版页

发布于 2024-10-22 02:54:31 字数 166 浏览 6 评论 0原文

我正在使用 Lightbox，但我只希望对样式表和 javascript 文件的引用位于网站某一页面（使用 Lightbox 的页面）的母版页标题中。如何以编程方式在页面加载中添加对样式表和 javascript 文件的引用？

样式表是“css”文件夹，三个 javascript 文件是“js”文件夹

尝试...

Page.ClientScript.RegisterClientScriptInclude("JScripts", ResolveUrl("~/js/JScripts.js"));

try...

Page.ClientScript.RegisterClientScriptInclude("JScripts", ResolveUrl("~/js/JScripts.js"));

将两个占位符（“JsPlaceholder”和“CSSPlaceholder”）添加到母版页上的标题并调用这些方法：

public void AddJavascriptFile(string path)
{
    PlaceHolder p = (PlaceHolder)Page.Header.FindControl("JsPlaceholder");
    p.Controls.Add(new LiteralControl(string.Concat("<script type='text/javascript' src='", path, "'></script>\n")));
}

public void AddCssFile(string urlPath)
{
    HtmlLink cssLink = new HtmlLink();
    cssLink.Href = path;
    cssLink.Attributes.Add("rel", "stylesheet");
    cssLink.Attributes.Add("type", "text/css");
    PlaceHolder p = (PlaceHolder)Page.Header.FindControl("CssPlaceholder");
    p.Controls.Add(cssLink);
}

Add two placeholders ("JsPlaceholder" and "CSSPlaceholder") to your header on master page and call those methods:

public void AddJavascriptFile(string path)
{
    PlaceHolder p = (PlaceHolder)Page.Header.FindControl("JsPlaceholder");
    p.Controls.Add(new LiteralControl(string.Concat("<script type='text/javascript' src='", path, "'></script>\n")));
}

public void AddCssFile(string urlPath)
{
    HtmlLink cssLink = new HtmlLink();
    cssLink.Href = path;
    cssLink.Attributes.Add("rel", "stylesheet");
    cssLink.Attributes.Add("type", "text/css");
    PlaceHolder p = (PlaceHolder)Page.Header.FindControl("CssPlaceholder");
    p.Controls.Add(cssLink);
}

尝试（在 C# 中，但你应该明白）：

protected override void OnLoad(EventArgs e)
{
    base.OnLoad(e);
    HtmlLink cssLink = new HtmlLink();

    //Create and configure the CSS link.
    cssLink.Attributes.Add("rel", "Stylesheet");
    cssLink.Attributes.Add("type", "text/css");
    cssLink.Href = "~/Path/To/File.css";

    //Add the CSS link to the page header.
    this.Header.Controls.Add(cssLink);

    //Add a script include to the page's ClientScript.
    this.ClientScript.RegisterClientScriptInclude("NameOfScript", this.ResolveUrl("~/Path/To/File.js"));
}

Try (in C# but you should get the idea):

protected override void OnLoad(EventArgs e)
{
    base.OnLoad(e);
    HtmlLink cssLink = new HtmlLink();

    //Create and configure the CSS link.
    cssLink.Attributes.Add("rel", "Stylesheet");
    cssLink.Attributes.Add("type", "text/css");
    cssLink.Href = "~/Path/To/File.css";

    //Add the CSS link to the page header.
    this.Header.Controls.Add(cssLink);

    //Add a script include to the page's ClientScript.
    this.ClientScript.RegisterClientScriptInclude("NameOfScript", this.ResolveUrl("~/Path/To/File.js"));
}

您可以这样做，

将其添加到您的标头中：

  <asp:placeholder runat="server" id="lightbox" visible="false">

        <link rel="stylesheet" href="/css/style.css" />
        <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.min.js"</script>
        </asp:placeholder>

并从您的代码隐藏集中

lightbox.visible=true;

您还应该注意，通常您希望在页面上保留尽可能多的 html，而不是将其放在代码隐藏中，这样设计人员就可以轻松地制作变化

you can do it like this

added this to your header:

  <asp:placeholder runat="server" id="lightbox" visible="false">

        <link rel="stylesheet" href="/css/style.css" />
        <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.min.js"</script>
        </asp:placeholder>

and from your codebehind set

lightbox.visible=true;

You should also note that normally you want to keep as much html on the page instead of having it in your codebehind so it will be easy for the designer to make changes
