以编程方式将 Javascript 文件添加到 .net 中的用户控件

Programmatically adding Javascript File to User Control in .net(以编程方式将 Javascript 文件添加到 .net 中的用户控件)

问题描述

如何以编程方式将 Javascript 文件添加到用户控件?

How do you add Javascript file programmatically to the user control?

我希望用户控件是一个完整的包 - 即我不想在使用它的页面上添加与用户控件相关的 javascript，因为我可以在控件本身内部执行它.

I want the user control to be a complete package - ie I don't want to have to add javascript that's related to the user control on the page where it's used, when I can do it inside the control itself.

既然用户控件中没有Page对象，你会怎么做呢?

Since there is no Page object in the user control, how would you do it?

推荐答案

在control.ascx.cs文件的Page_Load方法中:

In the Page_Load method of control.ascx.cs file:

LiteralControl jsResource = new LiteralControl();
jsResource.Text = "<script type="text/javascript" src="js/mini-template-control.js"></script>";
Page.Header.Controls.Add(jsResource);

HtmlLink stylesLink = new HtmlLink();
stylesLink.Attributes["rel"] = "stylesheet";
stylesLink.Attributes["type"] = "text/css";
stylesLink.Href = "css/mini-template-control.css";
Page.Header.Controls.Add(stylesLink);

这会将css和Javascript加载到主页的head标签中，只要确保head有runat="server".

This will load css and Javascript into the head tag of the main page, just make sure that the head has runat="server".
