推荐答案
更新:
ECMAScript 6(ES6)引入了一种新的文字,即 模板文字 。它们有许多功能,其中包括变量插值,但最重要的是,对于这个问题,它们可以是多行的。
Update:
ECMAScript 6 (ES6) introduces a new type of literal, namely template literals. They have many features, variable interpolation among others, but most importantly for this question, they can be multiline.
模板文字由反引号:
var html = `
<div>
<span>Some HTML here</span>
</div>
`;
(注意:我不主张在字符串中使用HTML)
(Note: I'm not advocating to use HTML in strings)
浏览器支持可以,但是您可以使用 transpilers 来提高兼容性。
Browser support is OK, but you can use transpilers to be more compatible.
Javascript没有here-document语法。你可以逃避文字换行,但接近:
Javascript doesn't have a here-document syntax. You can escape the literal newline, however, which comes close:
"foo \
bar"
