https://hugozh.cn/functions/compare/conditional/ <h2 id="用法">用法</h2> <p><code>compare.Conditional</code> 函数根据控制参数的值返回两个参数之一。如果 <code>CONTROL</code> 为真值，函数返回 <code>ARG1</code>，否则返回 <code>ARG2</code>。</p> <p>与其他语言中的<a href="https://en.wikipedia.org/wiki/Ternary_conditional_operator" target="_blank" rel="noopener">三目运算符</a>不同，<code>compare.Conditional</code> 函数不进行<a href="https://en.wikipedia.org/wiki/Short-circuit_evaluation" target="_blank" rel="noopener">短路求值</a>。无论 <code>CONTROL</code> 的值是什么，它都会对 <code>ARG1</code> 和 <code>ARG2</code> 两者求值。</p>

函数如果第二个参数已设置则返回第二个参数，否则返回第一个参数。</p> <aside class="callout callout-note"> <p class="callout-title">说明</p> <div class="callout-body"><p>当第二个参数是布尔值 <code>false</code> 时，<code>compare.Default</code> 函数返回
