在JavaScript中编写多行字符串最简洁的方法是什么？ [英] What's the cleanest way to write a multiline string in JavaScript?

问题描述

它实际上不需要添加换行符，只是可读的东西。

It doesn't really have to add newlines, just something readable.

还有什么比这更好的吗？

Anything better than this?

str = "line 1" +
      "line 2" +
      "line 3";

推荐答案

几乎与NickFitz的答案相同：

var str = [""
    ,"line 1"
    ,"line 2"
    ,"line 3"
].join("");
// str will contain "line1line2line3"

差异，代码稍微更易于维护因为可以重新排序行而不考虑逗号的位置。没有语法错误。

The difference, the code is slightly more maintainable because the lines can be re-ordered without regard to where the commas are. No syntax errors.
