Background music for webpages

When browsing the web, you will definitely have a web page with background music. Steps in the wonderful music to the infinity space of the Internet, you can really be beautiful! But the background music can only be a track, and it is not universal. If the background music of the web page allows visitors to choose any selection in a predetermined multi-track, becomes a background music, which believes that there will be more visits to stop. In fact, we can use the JavaScript script to write a program that replaces background music, realize any options for background music in web pages, let your web page will win. Let's first explain the design ideas and implementation methods of the program, followed by the complete sample program, I believe everyone will become a web activity background music.

I. Designing Ideas and Implementation 1. First establish embedded tag in HTML, embedded to selectable track files, *. Wav, *. Au, *. MID, etc., code as follows: The loop = -1 is loop = -1 let the track repeats AutoStart = false prohibiting tracks After embedding, Hidden = true will hide it, not visible 2. By means ------ No ------

The playing statement is changed to Document.name.Run (). 4. Add OnLoad = "Check_ok" in the tag of the HTML document, initialize the browser authentication variable MSIE4 (freely set variable name) to meet the program's requirements for the browser to prevent the browser An abnormal appearance is asked. Second, the annotation is detailed, the complete sample program list

activity background music </ Title></p> <p><script language = "javascript"> <! - var msie4 = false;</p> <p>/ / Define the function of the detection browser Function check_ok () {var nav = window.navigator.USERAGENT; VAR IE_OK = Nav.Indexof ("msie"); if (IE_ok> 0) // is Microsoft Internet Explorer Msie4 = PARSEINT Nav.Substring (IE_ok 5, Nav.indexof (".", IE_ok))> = 4; // IE 4.0 or above version}</p> <p>/ / Define the function of change background music function function my_sound () {if (msie4) // is IE 4.0 or higher version {if (Document.my_Music.Opt.Value == "1") // Select the track 1 {document.music2 .stop (); // Close another track Document.music1.play (); // Play track} else {if (Document.my_Music.opt.value == "2") // Select the track 2 {document.

Var IE_ok = Nav.indexOf in the check_ok function; is whether it contains "MSIE" in the detection browser name to determine if it is an IE browser; 2, the My_Sound function is (Document. " MY_MUSIC.OPT.VALUE == "2") determines the selected track, its standard format is IF (Document. Table Single name .Select Object Name. Value == Option VALUE Value) 3, the above program is Written as an example of two tracks, you can modify the procedure according to the method described above, add or decrease the optional tracks; 4.
