js跳轉

window.location.href = ;

js刷新

window.location.reload();

與IE8或更高版本兼容:

< META http-equiv ="X-UA-Compatible" content ="IE=EmulateIE7" />

< bgsound id ="oBGSound" autostart ="true" loop ="true" hidden ="true" />

控制聲音播放: 

$('#oBGSound').attr('src', "./chimes.wav");

懸浮div的

style:
position:absolute;font-size:8px;z-index:2;text-align:center;width: 325px;height: 215px;

最核心的是

z-index:2;

兼容各瀏覽器的flash

< object width ="960" height ="60" >
< param name ="movie" value ="*.swf" > </param>
< param name ="allowFullScreen" value ="true" > </param>
< param name ="wmode" value ="opaque" > </param>
< embed src ="*.swf" type ="application/x-shockwave-flash" wmode ="transparent" allowfullscreen ="true" width ="960" height ="60" > </embed>
</object>

用ajax向另外一個頁面發送 上萬個js字符串時, 若是採用逗號鏈接,則很是耗cpu, 若是採用js數組,則基本不佔用cpu,並且速度很快

jquery ajax function:
dataType use 'json' is the best way to return multiple-dimention array
use 'xml' is also good but waste network package size
use 'text' for simple return data, do not use implode and explode at the same time for complicated return data

跨域 cookie: http://www.w3.org/P3P/ table td 等的寬度寫死, 會使瀏覽器不執行動態的計算, 能夠使頁面快速顯示出來 當有大量的td須要隱藏, 同時大量的其它td須要顯示, 同理, 爲了會使瀏覽器不執行動態的計算, 在td裏用span,改爲大量span隱藏和顯示, 執行速度提升數十倍 gb2312, gbk 彷佛都不如用gb18030
