Does javascript have literal strings?
提问by DevelopingChris
In c# and ruby and many other languages you can denote a string as to not need escaping.
in c# its like this
在 c# 和 ruby 以及许多其他语言中，您可以将字符串表示为不需要转义。
在 c# 中它是这样的
string s = @"\whatever\this\is";
the results are when printed
结果在打印时
\whatever\this\is
my question is, is this supported in any form in javascript?
我的问题是，这在 javascript 中以任何形式支持吗？

I don't know what you're getting at, but one way to get around the problem of escaping (etc) is use a trick that John Resig seems to like a lot. You include <script>blocks in a page, but give them a "type" like "text/plain" to make sure that the browser doesn't hand them over to Javascript. Then use the text of the script block for whatever you like.
我不知道你在说什么，但是解决转义（等）问题的一种方法是使用 John Resig 似乎很喜欢的一个技巧。您<script>在页面中包含块，但给它们一个“类型”，如“文本/纯文本”，以确保浏览器不会将它们交给 Javascript。然后将脚本块的文本用于您喜欢的任何内容。
<script id='a_string' type='text/plain'>
Here is some stuff.
There might be some \escape sequences in it.
</script>
Then you can grab that with $('#a_string').text()(or with getElementByIdif you're not using jQuery or something like that).
然后你可以用$('#a_string').text()（或者getElementById如果你不使用jQuery或类似的东西）抓住它。
edit:Here's John Resig's explanation about why dropping stuff into script blocks like that is a good idea:
编辑：这是 John Resig 关于为什么像这样将内容放入脚本块是个好主意的解释：
Quick tip: Embedding scripts in your page that have a unknown content-type (such is the case here - the browser doesn't know how to execute a text/html script) are simply ignored by the browser - and by search engines and screenreaders. It's a perfect cloaking device for sneaking templates into your page. I like to use this technique for quick-and-dirty cases where I just need a little template or two on the page and want something light and fast.
快速提示：在页面中嵌入具有未知内容类型的脚本（这里就是这种情况 - 浏览器不知道如何执行文本/html 脚本）会被浏览器忽略 - 以及搜索引擎和屏幕阅读器. 这是一个完美的隐藏设备，可以将模板潜入您的页面。我喜欢将这种技术用于快速而肮脏的情况，在这种情况下，我只需要页面上的一两个小模板，并且想要轻松快速的东西。

Literal strings are available through the use of ES6 language features. Node v4.x now supports these and around 90% of the other ES6 additions as well.
文字字符串可通过使用 ES6 语言功能获得。Node v4.x 现在支持这些以及大约 90% 的其他 ES6 添加。

In JS string literals are known as Template Strings. And the syntax is pretty straight forward.
在 JS 中，字符串文字被称为模板字符串。语法非常简单。

Just escape the escapes
只是逃避逃避
var myCrazyString = "\yes\we\have\no\bananas"

This will work as long as you don't throw a \xinto the string!
只要您不将 a\x放入字符串中，这就会起作用！
var str = String.raw`\whatever\this\is`;

I know it is six years late now, but I've got one solution to this ;)
我知道现在已经晚了六年，但我有一个解决方案;)
function literalString(regex) {
return ('' + regex).slice(1, -1);
};
O.innerHTML = literalString(/\whatever\this\is/);<pre id=O>You basically convert a regex to string and removes the first and last characters.
您基本上将正则表达式转换为字符串并删除第一个和最后一个字符。
