问题描述

我有字符串:@address = "10 Madison Avenue, New York, NY - [phone]"像这样拆分它的最佳方法是什么?

I have string: @address = "10 Madison Avenue, New York, NY - [phone]" What's the best way to split it like this?

<p>10 Madison Avenue,</p>
<p>New York, NY - [phone]</p>

推荐答案

String#split 有第二个参数，结果数组中返回的最大字段数:http://ruby-doc.org/core/classes/String.html#M001165

String#split has a second argument, the maximum number of fields returned in the result array: http://ruby-doc.org/core/classes/String.html#M001165

@address.split(",", 2) 将返回一个包含两个字符串的数组，在第一次出现,"时进行拆分.

@address.split(",", 2) will return an array with two strings, split at the first occurrence of ",".

它的其余部分只是使用插值来构建字符串，或者如果您想让它更通用，例如 Array#map 和 #join 的组合

the rest of it is simply building the string using interpolation or if you want to have it more generic, a combination of Array#map and #join for example

@address.split(",", 2).map {|split| "<p>#{split}</p>" }.join("\n")
