The example in this article describes the implementation method of javascript background clock. Share it with everyone for your reference. The details are as follows:
The following is the full code for this effect. [Better to start with an empty page]
<html> <head> <TITLE>背景时钟</TITLE> <script language=javaScript> <!--// function clockon() { thistime= new Date() var hours=thistime.getHours() var minutes=thistime.getMinutes() var seconds=thistime.getSeconds() if (eval(hours) <10) {hours="0"+hours} if (eval(minutes) < 10) {minutes="0"+minutes} if (seconds < 10) {seconds="0"+seconds} thistime = hours+":"+minutes+":"+seconds if(document.all) { bgclocknoshade.innerHTML=thistime bgclockshade.innerHTML=thistime } if(document.layers) { document.bgclockshade.document.write('<div id="bgclockshade" style="position:absolute;visibility:visible;font-family:Verdana;color:FFAAAAA;font-size:120px;top:10px;left:152px">'+thistime+'</div>') document.bgclocknoshade.document.write('<div id="bgclocknoshade" style="position:absolute;visibility:visible;font-family:Verdana;color:DDDDDD;font-size:120px;top:10px;left:150px">'+thistime+'</div>') document.close() } var timer=setTimeout("clockon()",200) } //--> </script> <link rel="stylesheet" href="../style.css"></head> <body onLoad="clockon()"> <div id="bgclockshade" style="position:absolute;visibility:visible;font-family:Arial;color:FF8888;font-size:120px;top:102px;left:152px"></div> <div id="bgclocknoshade" style="position:absolute;visibility:visible;font-family:Arial;color:DDDDDD;font-size:120px;top:100px;left:150px"></div> <div id="mainbody" style="position:absolute; visibility:visible"> </div> </body> </html>
Note: The position of the clock display needs to be determined by modifying the TOP and LEFT parameters. TOP represents the pixel value of the layer from the top of the display, and LEFT represents the pixel value of the layer to the left.
I hope this article will be helpful to everyone’s JavaScript programming design.
