<h1>Arrayx (Array 扩展)<span><a class="mark" href="#arrayx_arrayx_array" id="arrayx_arrayx_array">#</a></span></h1>
|
|
<p>Arrayx 用于扩展 JavaScript 标准内置对象 Array 的功能 (参阅 <a href="glossaries.html#glossaries_内置对象扩展">内置对象扩展</a>).</p>
|
|
<p>Arrayx 全局可用:</p>
|
|
<pre><code class="lang-js">console.log(typeof Arrayx); // "object"
|
|
console.log(typeof Arrayx.union); // "function"
|
|
</code></pre>
|
|
<p>当启用内置扩展后, Arrayx 将被应用在 Array 及其原型上:</p>
|
|
<pre><code class="lang-js">console.log(typeof Array.prototype.union); // "function"
|
|
console.log(typeof [].union); // "function"
|
|
</code></pre>
|
|
<h2>启用内置扩展<span><a class="mark" href="#arrayx" id="arrayx">#</a></span></h2>
|
|
<p>内置扩展默认被禁用, 以下任一方式可启用内置扩展:</p>
|
|
<ul>
|
|
<li>在脚本中加入代码片段: <code>plugins.extendAll();</code> 或 <code>plugins.extend('Array');</code></li>
|
|
<li>AutoJs6 应用设置 - 扩展性 - JavaScript 内置对象扩展 - [ 启用 ]</li>
|
|
</ul>
|
|
<p>当上述应用设置启用时, 所有脚本均默认启用内置扩展.<br>当上述应用设置禁用时, 只有加入上述代码片段的脚本才会启用内置扩展.<br>内置扩展往往是不安全的, 除非明确了解内置扩展的原理及风险, 否则不建议启用.</p>
|
|
<h2>排序稳定性<span><a class="mark" href="#arrayx_1" id="arrayx_1">#</a></span></h2>
|
|
<p>Arrayx 的诸多排序方法, 如 [ sortBy / sortDescending / sortByDescending / sorted / sortedBy / sortedDescending / sortedByDescending ] 等, 其内部实现均调用了 JavaScript 的原生方法 <a href="https://developer.mozilla.org/zh-CN/docs/Web/JavaScript/Reference/Global_Objects/Array/sort">Array.prototype.sort</a>.</p>
|
|
<p>自 ES10 (ECMAScript 2019) 起, <a href="https://tc39.es/ecma262/#sec-array.prototype.sort">规范</a> 要求 Array.prototype.sort 为稳定排序, 因此 Arrayx 的排序方法也是稳定的.</p>
|
|
<blockquote>
|
|
<p>参阅: <a href="https://developer.mozilla.org/zh-CN/docs/Web/JavaScript/Reference/Global_Objects/Array/sort#%E6%8E%92%E5%BA%8F%E7%A8%B3%E5%AE%9A%E6%80%A7">MDN</a></p>
|
|
</blockquote>
|
|
<h2>排序方式<span><a class="mark" href="#arrayx_2" id="arrayx_2">#</a></span></h2>
|
|
<p>Arrayx 排序方法中的 selector (条件选择器) 使用的 compareFn (比较函数) 与默认的稍有不同.<br>默认的比较函数按照转换为字符串的诸个字符的 Unicode 位点进行 <strong>升序</strong> 排序, 例如 80 会被排列到 9 之前.<br>而 Arrayx 排序方法的 selector 则采用简单的直接比较方法:</p>
|
|
<pre><code class="lang-js">/* Arrayx 使用的 compareFn. */
|
|
(a, b) => a === b ? 0 : a > b ? 1 : -1;
|
|
</code></pre>
|
|
<p>因此对于 number 数组的排序会出现不同的结果:</p>
|
|
<pre><code class="lang-js">console.log([ 80, 70, 9 ].sort()); // [ 70, 80, 9 ]
|
|
console.log(Arrayx.sorted([ 80, 70, 9 ])); // [ 9, 70, 80 ]
|
|
</code></pre>
