記錄一個(gè)自己作的小作品，一個(gè)js模擬的select。

最近迷茫于javascript的閉包與繼承，寫一個(gè)小東西找找感覺。

JS+CSS模擬Select下拉框，選擇表單效果

網(wǎng)頁(yè)中使用Select語(yǔ)法實(shí)現(xiàn)的下拉框是很普遍的，但是您有沒有見過使用JS+CSS模擬的Select下拉框？并且可以選擇表單哦，盡管代碼復(fù)雜了點(diǎn)，但是對(duì)于我們了解此類特效非常有幫助。

在不改變HTML結(jié)構(gòu)的前提下，可更改其它樣式。建議用IE8與FF瀏覽，可與默認(rèn)樣式進(jìn)行對(duì)比。

發(fā)布一來是為了記錄自己學(xué)習(xí)過程，二來想請(qǐng)朋友指點(diǎn)一下迷津，哪些地方欠妥或者有更好的思路可以給我指點(diǎn)一下，謝謝。
