關(guān)鍵字描述：提示 效果 消息 模仿 " popTop if else & screen.width-2

你一定很喜歡像QQ或者M(jìn)SN好友登錄提示的效果吧，那么怎么樣能在網(wǎng)頁中實(shí)現(xiàn)呢？正好我在藍(lán)色理想中發(fā)現(xiàn)了這段代碼，貼出給大家看看（注意，如果使用以下代碼，先將全角“＜＞”替換成半角的“<>”才能正常使用）：

＜SCRIPT＞
var oPopup = window.createPopup();
var popTop=50;
function popmsg(msgstr){
varwinstr="＜table style=\"border: 1 solid #FFA6CA\" width=\"241\"height=\"172\" border=\"0\" cellpadding=\"0\" cellspacing=\"0\" background=\"" ＞";
winstr ="＜tr＞＜td height=\"30\"＞ ＜/td＞＜/tr＞＜tr＞＜tdalign=\"center\"＞＜table width=\"90%\" height=\"110\" border=\"0\"cellpadding=\"0\" cellspacing=\"0\"＞";
winstr ="＜tr＞＜tdvalign=\"top\" style=\"font-size:12px; color: red; face: Tahoma\"＞"msgstr "＜/td＞＜/tr＞＜/table＞＜/td＞＜/tr＞＜/table＞";
oPopup.document.body.innerHTML = winstr;
popshow();
}
function popshow(){
window.status=popTop;
if(popTop＞1720){
clearTimeout(mytime);
oPopup.hide();
return;
}else if(popTop＞1520&&popTop＜1720){
oPopup.show(screen.width-250,screen.height,241,1720-popTop);
}else if(popTop＞1500&&popTop＜1520){
oPopup.show(screen.width-250,screen.height (popTop-1720),241,172);
}else if(popTop＜180){
oPopup.show(screen.width-250,screen.height,241,popTop);
}else if(popTop＜220){
oPopup.show(screen.width-250,screen.height-popTop,241,172);
}
popTop =10;
var mytime=setTimeout("popshow();",50);
}
