The example of this article is about JS to achieve a time limit to disappear image method. Share to everyone for your reference. The implementation methods are as follows:
<title> vanishing picture in the specified time </title>
<body>
<script language=javascript>
<!--Hide the script from old browsers--
1) make a 88*31 logo.
if (document.images)
var staticlogo=new Image (758,100)
2) Set the path of the logo.
Staticlogo.src= "/images/banner.gif"
3) The following is the connection of the logo representative.
var logolink= "http://wwwww.jb51.net/"
4) set the ALT attribute.
var alttext= "Code Home"
5 The following properties are set to 1 or 0 (1 is IE specific, so that the logo looming)
var fadeintoview=1
/* 6 finally set the logo display time, such as 12 seconds, the value of 0 is always displayed
*/
var visibleduration=5
function Regenerate () {
Window.location.reload ()
}
function Regenerate2 () {
if (document.layers)
settimeout ("Window.onresize=regenerate", 400)
}
var fadeset= '
if (Fadeintoview)
Fadeset= "Filter:alpha (opacity=0)"
if (document.all)
document.write (' <span id= ' logo "" style= "' +fadeset+ ';p osition:absolute;top:100;width: ' +staticlogo.width+ '; Height: ' +staticlogo.height+ ' "></span>")
function Bringintoview () {
if (logo.filters.alpha.opacity<=95)
Logo.filters.alpha.opacity+=5
else{
Clearinterval (Viewit)
if (visibleduration!=0)
settimeout ("logo.style.visibility= ' hidden '", visibleduration*1000)
}
}
function Createlogo () {
Staticimage=new Layer (100)
staticimage.left=-300
staticimage.top=120
Staticimage.document.write (' <a href= "' +logolink+ '" ></a> ')
Staticimage.document.close ()
Staticimage.visibility= "Show"
Regenerate2 ()
Staticitns ()
}
if (document.layers)
Window.onload=createlogo;
if (document.all) {
w=2
h=2
Logo.style.left=w
Logo.style.top=h
}
function Logoit () {
var w2=document.body.scrollleft+w
var h2=document.body.scrolltop+h
Logo.style.left=w2
Logo.style.top=h2
}
function Logoit2 () {
Staticimage.left=pagexoffset+2
Staticimage.top=pageyoffset+2
}
function Insertimage () {
Logo.innerhtml= ' <a href= "' +logolink+ '" ></a " > '
if (Fadeintoview)
Viewit=setinterval ("Bringintoview ()", 100)
else{
if (visibleduration!=0)
settimeout ("logo.style.visibility= ' hidden '", visibleduration*1000)
}
}
if (document.all) {
Window.onscroll=logoit
Window.onresize=new Function ("Window.location.reload ()")
Window.onload=insertimage
}
function Staticitns () {
SetInterval ("Logoit2 ()", 90)
if (visibleduration!=0)
settimeout ("staticimage.visibility= ' Hide '", visibleduration*1000)
}
-->
</SCRIPT>
</body>
<br>
<br>
<br>
<br>
<br>
<br> picture automatically disappears after 5 seconds.

I hope this article will help you with your JavaScript programming.
