在本文中，我們將通過使用名為script.aculo.us的JavaScript庫(從一個平滑過渡到另一個平滑過渡)來演示ScrollTo的效果。我們也可以調整效果的持續時間。
用法:
Effect.ScrollTo('element_id', { duration:'0.2', offset:-20 });
注意：要使用此庫，我們應該先安裝該庫，然後在程序中使用它。為此，您可以點擊此鏈接http://script.aculo.us/downloads。
方法：為了演示該函數的用法，我們編寫了一小段代碼。我們編寫了一個名為ShowEffect()方法的小型JavaScript函數，該函數使用此庫的Effect.ScrollTo()方法。通過單擊“單擊我滾動”，您將清楚地看到效果。
例：要查看效果，請先下載該庫，然後在本地環境中打開此程序。

a recent survey conducted by Stack Overflow,
<br />JavaScript is the most popular language

JavaScript was created in the first place
for DOM manipulation.<br /> Earlier websites
were mostly static, after JS was created
dynamic Web sites were made.<br /> Functions
in JS are objects. They may have properties
and methods just like another object.<br />
They can be passed as arguments in other
functions.<br />Can handle date and time.<br />
Performs Form Validation although the forms are
created using HTML.<br />No compiler needed.<br />
