How to add CSS, JS, and Meta tags to the Asp.net background

The following describes how to add CSS, JS, and Meta tags to the backend of Asp.net. Here we write functions for future use. If a function is placed in a Page class, the Page parameter is optional.
First, import the namespace using System. Web. UI. HtmlControls;
Copy codeThe Code is as follows:
///
/// Add the JS script Link
///
/// Page
/// Path
Public void AddJS (System. Web. UI. Page page, string url)
{
HtmlGenericControl jsControl = new HtmlGenericControl ("script ");
JsControl. Attributes. Add ("type", "text/javascript ");
JsControl. Attributes. Add ("src", url );
Page. Header. Controls. Add (jsControl );
}


///
/// Add JS script content
///
/// Page
/// Script content
Public void AddScript (System. Web. UI. Page page, string content)
{
HtmlGenericControl scriptControl = new HtmlGenericControl ("script ");
ScriptControl. Attributes. Add ("type", "text/javascript ");
ScriptControl. InnerHtml = content;
Page. Header. Controls. Add (scriptControl );
}


///
/// Add a CSS style Link
///
/// Page
/// Path
Public void AddCss (System. Web. UI. Page page, string url)
{
HtmlLink link = new HtmlLink ();
Link. Href = url;
Link. Attributes. Add ("rel", "stylesheet ");
Link. Attributes. Add ("type", "text/css ");
Page. Header. Controls. Add (link );
}


///
/// Add CSS style content
///
/// Page
/// Style content
Public void AddStyle (System. Web. UI. Page page, string content)
{
HtmlGenericControl styleControl = new HtmlGenericControl ("style ");
StyleControl. Attributes. Add ("type", "text/css ");
StyleControl. InnerHtml = content;
Page. Header. Controls. Add (styleControl );
}


///
/// Add a Meta tag
///
/// Page
/// Meta name
/// Meta content
Public void AddMeta (System. Web. UI. Page page, string name, string content)
{
HtmlMeta = new HtmlMeta ();
Meta. Name = name;
Meta. Content = content;
Page. Header. Controls. Add (meta );
}
