下面這個(gè)程序是用light濾鏡模擬雷達(dá)屏幕，并且有一架飛機(jī)被發(fā)現(xiàn)。當(dāng)然編這個(gè)程序要對(duì)script 比較熟悉，還要知道lighy濾鏡的屬性和方法 !DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" HTML HEAD TITLE css demo /TITLE META content="text/html; charset=gb2312" http-equiv=Content-Type STYLE DIV { FILTER: blur(add=ture,direction=135,strength=10); WIDTH: 800px } /STYLE SCRIPT var light_x=20 var light_y=20 var light_z=40 var xinc=10; var yinc=10; var r=100; var deg=0; var deg1; var rad; var pointangle; var planelight_x=20 var planelight_y=120 var planelight_z=3 var conversion=(2*3.14159)/360 function movefilt() { light_x=r+r*Math.cos(deg*conversion); light_y=r+r*Math.sin(deg*conversion); deg+=10; if(deg==360) deg=0; body1.filters[0].movelight(0,light_x,light_y,light_z,1); pointangle=Math.atan((planelight_y-r)/(planelight_x-r))/conversion; if((planelight_x r) (planelight_y r)) pointangle+=180; if((planelight_x r) (planelight_y r)) pointangle+=360; if((planelight_x r) (planelight_y r)) pointangle+=180; if((deg-10 =pointangle) (pointangle =deg)) body1.filters[0].movelight(2,planelight_x,planelight_y,planelight_z,1); mytimeout=setTimeout('movefilt()',100); } function moveplanes() { planelight_x++; planelight_y++; if(planelight_y 200) planelight_y=0; if(planelight_x 200) planelight_x=0; timeout2=setTimeout('moveplanes()',500); } function go(){ body1.filters.light.addcone(100,100,0,light_x,light_y,0,225,0,150,10); body1.filters.light.addambient(0,225,0,20) body1.filters.light.addpoint(planelight_x,planelight_y,3,0,225,0,100); var x=0; movefilt(); moveplanes(); } function zap() { if(myimg.filters.glow.enabled==1) {myimg.filters.glow.enabled=0; } if (myimg.filters.blendTrans.status==0) { myimg.filters.blendTrans.apply(); myimg.filters.glow.enabled=1; myimg.filters.blendTrans.play(); } } /SCRIPT META content="MSHTML 5.00.2614.3500" name=GENERATOR /HEAD BODY onload=go() TABLE border=0 width="89%" TBODY TR TD IMG src="http://www.jzxue.com/System/uploads/userup/1105/010925541623.jpg" name="body1" width=200 height=200 hspace=300 id=body1 /TD /TR /TBODY /TABLE P /P /BODY /HTMLhtml教程
