在上网时我们注意往往是网站页面内容,而状态栏不会被人太多注意,如果我们给页面的状态栏加一些特效,肯定会使你的网站增添一道风景,下面就给大家介绍7种常见的状态栏特效的Javascript代码。
特效一:滚动显示
第一步:把如下代码加入< head>区域中
< script language="Javascript">
< !--
function scrollit(seed) {
var m1 = "HI:你好! ";
var m2 = "欢迎访问网页教学网";
var m3 = "请多提意见,谢谢! ";
var m4 = "欢迎您下次再来!";
var m5 = "www.webjx.com ";
var msg=m1 m2 m3 m4 m5;
var out = " ";
var c = 1;
if (seed > 100) {
seed--;
cmd="scrollit(" seed ")";
timerTwo=window.setTimeout(cmd,100);
}
else if (seed < = 100 && seed > 0) {
for (c=0 ; c < seed ; c ) {
out =" ";
}
out =msg;
seed--;
window.status=out;
cmd="scrollit(" seed ")";
timerTwo=window.setTimeout(cmd,100);
}
else if (seed < = 0) {
if (-seed < msg.length) {
out =msg.substring(-seed,msg.length);
seed--;
window.status=out;
cmd="scrollit(" seed ")";
timerTwo=window.setTimeout(cmd,100);
}
else {
window.status=" ";
timerTwo=window.setTimeout("scrollit(100)",75);
}
}
}
//-->
< /script>
第二步:把如下代码加入< body>区域中
< body background=bag.gif onLoad="scrollit(100)">
特效二:文字从状态栏的右边循环弹出
把如下代码加入< head>区域中
< script language="Javascript">
var MESSAGE = "欢迎来到网页教学网,请多提意见。谢谢! "
var POSITION = 150
var DELAY = 10
var scroll = new statusMessageObject()
function statusMessageObject(p,d) {
this.msg = MESSAGE
this.out = " "
this.pos = POSITION
this.delay = DELAY
this.i = 0
this.reset = clearMessage}
function clearMessage() {
this.pos = POSITION}
function scroller() {
for (scroll.i = 0; scroll.i < scroll.pos; scroll.i ) {
scroll.out = " "}
if (scroll.pos >= 0)
scroll.out = scroll.msg
else scroll.out = scroll.msg.substring(-scroll.pos,scroll.msg.length)
window.status = scroll.out
scroll.out = " "
scroll.pos--
if (scroll.pos < -(scroll.msg.length)) {
scroll.reset()}
setTimeout ('scroller()',scroll.delay)}
function snapIn(jumpSpaces,position) {
var msg = scroll.msg
var out = ""
for (var i=0; i< position; i )
{out = msg.charAt(i)}
for (i=1;i< jumpSpaces;i )
{out = " "}
out = msg.charAt(position)
window.status = out
if (jumpSpaces < = 1) {
position
if (msg.charAt(position) == ' ')
{position }
jumpSpaces = 100-position
} else if (jumpSpaces > 3)
{jumpSpaces *= .75}
else
{jumpSpaces--}
if (position != msg.length) {
var cmd = "snapIn(" jumpSpaces "," position ")";
scrollID = window.setTimeout(cmd,scroll.delay);
} else { window.status=""
jumpSpaces=0
position=0
cmd = "snapIn(" jumpSpaces "," position ")";
scrollID = window.setTimeout(cmd,scroll.delay);
return false }
return true}
snapIn(100,0);
< /script>
特效三:title弹出效果
把如下代码加入< head>区域中
< script language="javascript">
< !-- Hide me
var index_count = 0;
var title_string = "欢迎光临网页教学网,(www.webjx.com)这里有许多电脑应用方面的文章
,是您学习网页制作技术的好去处!希望您能够常来!";
var title_length = title_string.length;
var cmon;
var kill_length = 0;
function loopTheScroll()
{
scrollTheTitle();
if(kill_length > title_length)
{
clearTimeout(cmon);
}
kill_length ;
cmon = setTimeout("loopTheScroll();",100)
}
function scrollTheTitle()
{
var doc_title = title_string.substring((title_length - index_count - 1),title_length);
