通常，我們通常會(huì)在變量中緩存許多這些對象，而不是重複對它們的引用。我們只是為這個(gè)簡單的示例而這樣做。 >

這是我們的最終演示：

<span>var animationHelper = AniJS.getHelper(),
</span>    spnLogin <span>= document.getElementById('spnLogin');
</span>
animationHelper<span>.validateLogin = function (e<span>, animationContext</span>) {
</span>    <span>var email = document.getElementById('txtLoginId').value;
</span>    <span>var pass = document.getElementById('txtLoginPass').value;
</span>    <span>if (email && pass) {
</span>      spnLogin<span>.innerHTML = 'Processing...';
</span>    <span>} else {
</span>      spnLogin<span>.innerHTML = 'Fill Required fields.';
</span>      animationContext<span>.run();
</span>    <span>}
</span><span>}</span>

什麼是Anijs，它如何工作？ anijs是CSS動(dòng)畫的聲明性處理庫。它允許開發(fā)人員使用簡單而直觀的語法創(chuàng)建動(dòng)畫，而無需編寫複雜的JavaScript代碼。 ANIJS通過在您的HTML元素中解析數(shù)據(jù)anijs屬性並執(zhí)行相應(yīng)的動(dòng)畫來工作。這使得管理和控制動(dòng)畫變得更容易，因?yàn)槟梢灾苯釉趆tml中定義它們。

>使用anijs創(chuàng)建動(dòng)畫涉及添加data-anijs屬性HTML元素並定義動(dòng)畫參數(shù)。 Data-Anijs屬性使用的簡單語法指定事件，動(dòng)畫元素，應(yīng)用動(dòng)畫和回調(diào)函數(shù)。您還可以使用ANIJS助手函數(shù)來控制動(dòng)畫流。

>我可以使用Anijs創(chuàng)建哪些類型的動(dòng)畫？

anijs anijs支持廣泛的CSS動(dòng)畫。您可以創(chuàng)建簡單的動(dòng)畫，例如淡出和幻燈片，以及涉及轉(zhuǎn)換和過渡的更複雜的動(dòng)畫。 ANIJS還支持動(dòng)畫鏈，使您可以創(chuàng)建以特定順序執(zhí)行的動(dòng)畫序列。

我可以使用anijs進(jìn)行響應(yīng)式設(shè)計(jì)嗎？
