## Description
|
|||
|
|
<section id="description"> <code>some</code>方法适用于数组，以检查是否有<em>任何</em>元素通过了特定的测试。它返回一个布尔值 - 如果任何值满足条件，则返回<code>true</code>否则返回<code>false</code> 。例如，以下代码将检查<code>numbers</code>数组中的任何元素是否小于10： <blockquote> var number = [10,50,8,220,110,11]; <br> numbers.some（function（currentValue）{ <br> return currentValue <10; <br> }）; <br> //返回true </blockquote></section>
