'和'之间有什么区别？在JavaScript？ [英] What is the difference between ' and " in JavaScript?

问题描述

我看到这个问题，我想知道JavaScript中的相同内容。

I saw this question and I am wondering about the same thing in JavaScript.

如果在JavaScript中创建字符串时使用字符'或字符'，则应用程序似乎表现相同。那么这两个字符之间有什么区别？

If you use the character ' or the character " when making strings in JavaScript, the application seems to behave the same. So what is the difference between these two characters?

我在使用'构建字符串时所看到的唯一优势是我可以执行以下操作：

The only advantage I have seen in using ' to build strings is that I can do stuff like:

var toAppend = '<div id="myDiv1"></div>';

而不是：

var toAppend = "<div id=\"myDiv1\"></div>";

我应该注意它们之间是否有任何显着差异？

Is there any significant difference between them that I should be aware of?

推荐答案

它们等同于所有意图和目的。如果你想在字符串中使用任何一个，那么最好是用另一个来创建正如你所注意到的那样，除此之外，它都是一样的。

They are equivalent for all intents and purposes. If you want to use either one inside a string, it is a good idea to use the other one to create the string, as you noted. Other than that, it's all the same.
