超長收藏：JavaScript常用腳本分享（上）

實用且必用的小腳本代碼:

腳本1：進入主頁以后自動播放聲音

<embed src="pnm://10.13.31.90/~kayvin/mihunji.rm" hidden=true autostart=true loop=true>

腳本2：進入主頁后自動最大話,省的去在自己單擊了

<script>
self.moveTo(0,0)
self.resizeTo(screen.availWidth,screen.availHeight)
</script>

腳本3：顯示現在時間的腳本

<script language=vbscript>document.write now</script>

腳本4：顯示最后修改時間的腳本

<script>document.write(document.lastModified)</script>

腳本5：設為首頁,加為收藏，加入頻道,啟動outlook發信

<a style="cursor:hand"
onclick="this.style.behavior="url(#default#homepage)";
this.setHomePage([url]http://10.13.31.90/~kayvin/[/url]);">">設為首頁</a>
<a style="cursor:hand"
onclick="window.external.AddFavorite(location.href,document.title);">加入收藏</a>
<a href=javascript：window.external.addChannel("typhoon.cdf")>加入頻道</a>
<a href="mailto:kayvin@sohu.com">與我聯系</a>

腳本6：狀態欄動態顯示現在時間

<script>
function see(){
window.setTimeout("see()",1000);
today=new Date();
self.status=today.toString();
}
</script>
<body onload=see()>

腳本7：關閉窗口的腳本

<a href=javascript：close()>[關閉窗口]</a>

腳本8：按下F12鍵,直接返回首頁

<script>function look(){
if(event.keyCode==123){document.location.href=http://10.13.31.90/~kayvin/}
}
if(document.onkeydown==null)
{document.onkeydown=look}
</script>

腳本9：后退,刷新,前進

<input type=button value=后退 onclick=history.go(-1)>
<input type=button value=刷新 onclick=history.go(-0)>
<input type=button value=前進 onclick=history.go(+1)>

腳本10：設定時間彈出窗口,4000=4秒,當然你可以自定義

<script>function l()
{
window.open(" 10.13.31.90/~kayvin/ ","name","width=500,height=150,border=0")
}
setTimeout("l()",4000)
</script>

二鼠標旁邊的提示信息,類似與163登錄后的頁面提示效果：

<a href="#" title="這是提示">tip</a>
<script Language="JavaScript">
//***********默認設置定義.*********************
tPopWait=50;//停留tWait豪秒后顯示提示。
tPopShow=5000;//顯示tShow豪秒后關閉提示
showPopStep=20;

document.write("<style type='text/css'id='defaultPopStyle'>");
document.write(".cPopText { background-color: #F8F8F5;color:#000000; border: 1px #000000 solid;font-color: font-size: 12px; padding-right: 4px; padding-left: 4px; height: 20px; padding-top: 2px; padding-bottom: 2px; filter: Alpha(Opacity=0)}");
document.write("</style>");
document.write("<div id='dypopLayer' style='position:absolute;z-index:1000;' class='cPopText'></div>");
function showPopupText(){
var o=event.srcElement;
MouseX=event.x;
MouseY=event.y;

}
function fadeOut(){
if(dypopLayer.filters.Alpha.opacity<popOpacity) {
dypopLayer.filters.Alpha.opacity+=showPopStep;
tFadeOut=setTimeout("fadeOut()",1);
}
else {

}
}
function fadeIn(){
if(dypopLayer.filters.Alpha.opacity>0) {
dypopLayer.filters.Alpha.opacity-=1;
tFadeIn=setTimeout("fadeIn()",1);
}
}
document.onmouseover=showPopupText;
</script>

三如果文字過長,則將過長的部分變成省略號顯示：

<DIV STYLE="width: 120px; height: 50px; border: 1px solid blue;
 overflow: hidden; text-overflow:ellipsis">
<NOBR>就是比如有一行文字，很長，表格內一行顯示不下.</NOBR>
</DIV>

五接收鍵盤指令的腳本:

<SCRIPT language="JavaScript">
<!--
var hotkey=97
var destination="http://www.wyev.com"
if (document.layers)
document.captureEvents(Event.KEYPRESS)
function backhome(e){
if (document.layers){
if (e.which==hotkey)
window.location=destination
}
else if (document.all){
if (event.keyCode==hotkey)
window.location=destination
}
}
document.onkeypress=backhome
//-->
</SCRIPT>
onkeydown="javascript：onenter();"
function onenter(){
if(event.keyCode==13){
alert("回車");
}
}

九 DIV的透明層實現:

、對transition屬性的認識

1、transition 屬性是一個簡寫屬性，可用于設置四個過渡屬性：

transition-property 過渡效果的 CSS 屬性的名稱（height、width、opacity等）。

transition-duration 完成過渡效果需要時間。

transition-timing-function 規定速度效果的速度曲線。

transition-delay 過渡效果何時開始（延遲時間）。

注：如果 transition-duration屬性時長為 0，就不會產生過渡效果。

2、漸變函數的值：

漸變函數是transition-timing-function；
其中貝塞爾曲線的預設值
 ease漸快，勻速，減慢cubic-bezier(0.25,0.1,0.25,1)
 ease-in漸快，勻速cubic-bezier(0.42,0,1,1)
 ease-out勻速，減慢cubic-bezier(0,0,0.58,1)
 ease-in-out和ease類似，但比ease的加速度大（幅度大）cubic-bezier(0.42,0,0.58,1)
 linear全程勻速cubic-bezier(0,0,1,1)

3、簡寫方式：transition：css屬性名過度時間漸變函數值延遲時間；

二、簡單動畫實例操作

1、先插入兩張圖片

<div class="A">
 <img src="img/吃藥.jpg" alt="">
 <img src="img/main_bg.jpg" alt="">
 </div>

2、給圖片設置樣式

<style>
 .A {
 margin: auto 100px;
 height: 400px;
 width: 600px;
 position: relative;
 }
 
 .A img:nth-child(1) {
 height: 300px;
 width: 300px;
 position: absolute;
 }
 
 .A img:nth-child(2) {
 height: 300px;
 width: 300px;
 position: absolute;
 transition: opacity 3s ease-in 2s;
 }
 
 .A img:nth-child(2):hover {
 opacity: 0;
 }
 
 img {
 height: 300px;
 width: 300px;
 }
 </style>

3、得到的動畫效果是：

周發布的Firefox52加入了對WebAssembly的支持，成為第一個支持WebAssembly標準的瀏覽器，而其它瀏覽器如Chrome57、Safari和Edge也都會陸續支持WebAssembly。

補充JavaScript的WebAssembly 正漸走向主流

WebAssembly源于Mozilla發起的Asm.js項目，設計補充而非取代JavaScript，它是一個二進制格式，容易翻譯到原生代碼，本地解碼速度比JS解析快得多，讓高性能的Web應用在瀏覽器上運行成為可能，比如視頻游戲、計算機輔助設計、視頻和圖像編輯、科學可視化等等。

未來，現有的生產力應用和JavaScript框架都有可能使用WebAssembly，能顯著降低加載速度，同時改進運行性能。開發者可以將針對CPU密集計算的WebAssembly庫整合到現有的Web應用中。
