join()方法将数组中所有的元素转化为字符串,并将这些字符串有逗号隔开合并成一个字符串作为方法的结果返回。如果调用时给定参数string,就将string作为在结果字符串中分开有各个数组元素形成的字符串的分隔符。 toString()方法返回一个包含数组中所有元素,且元素之间以逗号隔开的字符串,该方法在将数值作为
问:如果我在 Bash 中有如下数组: FOO=( a b c ) 如何用逗号连接元素?...例如,生成字符串 a,b,c 答:如果分隔符为单个字符, 方法一: function join_by { local IFS="$1"; shift; echo "$*"; } 测试示例如下...: join_by , a "b c" d #output: a,b c,d join_by / var local tmp ...

split() 方法是 String 对象方法,与 join() 方法操作正好相反。该方法可以指定两个参数,第 1 个参数为分隔符,指定从哪儿进行分隔的标记;第 2 个参数指定要返回数组的长度。 vars="1==2== 3==4 ==5"; vara=s.split("=="); console.log(a); console.log(a.constructor==Array); http://c.bianch...

ClickHouse提供了非常丰富的函数库,主要分为两种函数:常规函数和聚合函数,除此之外,还有 ‘arrayJoin’ 等特殊函数,我们将分别介绍。需要注意的是ClickHouse具有强类型限制,换句话说,它不进行类型之间的隐式转换,每个函数都适用于特定的类型参数。这意味着有时需要使用类型转换函数。
