JavaScript模板文字（模板字符串）中的转义美元符号 [英] Escape dollar sign in JavaScript template literals (template strings)

问题描述

我正在使用JavaScript ES6的新模板文字（模板字符串）语法这里的文档，我不太确定如何转义用于断开字符串以添加参数的美元符号。

I am using the new template literals (template strings) syntax of JavaScript ES6 Docs Here and I am not quite sure how to escape the dollar sign that is used to break the string to add a parameter.

这就是我的意思尝试做：

Here is what I am trying to do:

var response = `I consent to my credit card being charged in the amount of
                 $ ${ total } for the purchase of ${ item.title } and any
                 applicable sales tax.`

正常。 。但我真的希望不要有 $ $ {title}

that works fine... but I would really prefer to not have that space $ ${title}

这样的空间，使最终结果看起来像这样：

that leaves the end result looking like :

...购买金额为$ 25.99 ...

... in the amount of $ 25.99 for the purchase...

我真的更希望

...购买金额为$ 25.99 ...

... in the amount of $25.99 for the purchase ...

我想这是可以的，或者显然我可以使用仍然有效的旧方法，但是知道如何解决此问题将非常不错。我链接到Mozilla文档，但在其中找不到任何内容，希望有人对如何解决这个问题有所了解

I guess that is ok, or obviously I could use the old way that still works, but it would be nice to know how to fix this. I linked to the Mozilla docs , and I can't find anything in there about it, hopefully someone has an idea how to fix this

推荐答案

var response = `I consent to my credit card being charged in the amount of
                 $${ total } for the purchase of ${ item.title } and any
                 applicable sales tax.`
