i have code, simple code, want automatically right , loop again (from right left, @ right side of window showed in left side again) right code make object infinitely move left right possible?
var imgobj = null; var animate; function init() { imgobj = document.getelementbyid('myimage'); imgobj.style.position = 'relative'; imgobj.style.left = '0px'; } function moveright() { imgobj.style.left = parseint(imgobj.style.left) + 10 + 'px'; animate = settimeout(moveright, 20); // call moveright in 20msec } function stop() { cleartimeout(animate); imgobj.style.left = '0px'; } window.onload = init;
<html> <head> <title>javascript animation</title> </head> <body> <form> <img id="myimage" src="/images/html.gif" /> <p>click buttons below handle animation</p> <input type="button" value="start" onclick="moveright();" /> <input type="button" value="stop" onclick="stop();" /> </form> </body> </html>
when image past width of window, needs have position reset zero. can modulus operator.
var imgobj = null; var animate; function init() { imgobj = document.getelementbyid('myimage'); imgobj.style.position = 'relative'; imgobj.style.left = '0px'; } function moveright() { var bodywidth = document.body.clientwidth; var newleft = parseint(imgobj.style.left) + 10 imgobj.style.left = newleft % bodywidth + 'px'; animate = settimeout(moveright, 20); // call moveright in 20msec } function stop() { cleartimeout(animate); imgobj.style.left = '0px'; } window.onload = init;
<html> <head> <title>javascript animation</title> </head> <body> <form> <img id="myimage" src="/images/html.gif" /> <p>click buttons below handle animation</p> <input type="button" value="start" onclick="moveright();" /> <input type="button" value="stop" onclick="stop();" /> </form> </body> </html>
