以编程方式在页眉中添加javascrip引用（或完整脚本）

Posted 2021-02-26

Place javascrip refernce or complete javascript code in page header from ascx or aspx file.

// add reference like this
 
htmlGenericControl script1 = new HtmlGenericControl("script");
script1.Attributes.Add("type", "text/javascript");
script1.Attributes.Add("src", "../js/prototype.js");
this.Page.Header.Controls.Add(script1);
 
 
// add full script like this
// first create string which contains your javascript
string YahooScript = "";
YahooScript = "
"
+ "YAHOO.util.Event.onContentReady("izbornik", function () {
"
+ "var oMenuBar = new YAHOO.widget.MenuBar("izbornik", {autosubmenudisplay: true, hidedelay: 750, lazyload: true });
"
+ "oMenuBar.render();
"
+ "});
";
 
// and then place javascript in header
HtmlGenericControl script3 = new HtmlGenericControl("script");
script3.Attributes.Add("type", "text/javascript");
script3.InnerHtml = YahooScript;
this.Page.Header.Controls.Add(script3);
 
 
// in aspx page you can add script using Literal control
// place Literal control in page Header in code view.
// create your script string
string temaSkripta = "";
temaSkripta = "
"
+ "function kojaTema()
"
+ "{"
+ "var tema = '" + tema + "';
"
+ "return tema;"
+ "}";
 
// find Literal in heder and make your string it's text.
Literal L = (Literal)Header.FindControl("Literal1");
L.Text = temaSkripta;
