你可以在不使用'或'的情况下创建JavaScript字符串吗？报价？ [英] Can you create a JavaScript string without using ' or " quotes?

问题描述

我有一个带有一些XML的JS文件，其中XML应该由服务器转换为单词。

I have a JS file with some XML in it, where the XML is supposed to get converted to a word by the server.

例如

var ip = "<lang:cond><lang:when test="$(VAR{'ip_addr'})">$(VAR{'ip_addr'})</lang:when></lang:cond>";

这会转换为：

var ip = "192.168.0.0";

但是，如果服务器无法按预期工作，我不希望有语法错误，这非常重要。目前会出现语法错误，因为该语言使用两种类型的引号。我想不出办法解决这个问题，但也许还有另一种方法可以在JavaScript中做引用？或者创建一个字符串？

However, in case the server doesn't work as intended, I don't want there to be a syntax error, and this is VERY important. Currently there would be a syntax error because the language uses both types of quotes. I can't think of a way to get around this, but perhaps there's another way to do quotes in JavaScript? Or to create a string?

例如，在Python中我会使用三重引号：

For example, in Python I'd use triple quotes:

ip = """<lang:cond><lang:when test="$(VAR{'ip_addr'})">$(VAR{'ip_addr'})</lang:when></lang:cond>"""

任何人都有一个好主意？

Anyone have a bright idea?

推荐答案

我不得不为项目创建没有引号的字符串。我们正在向浏览器提供可执行的客户端javascript以用于内部网站。接收端在显示时会删除双引号和单引号。我发现绕过引号的一种方法是将我的字符串声明为正则表达式。

I have had to create strings without quotes for a project as well. We were delivering executable client javascript to the browser for an internal website. The receiving end strips double and single quotes when displayed. One way I have found to get around quotes is by declaring my string as a regular expression.

var x = String(/This contains no quotes/);
x = x.substring(1, x.length-1);
x;
