为什么会出现意外的模板字符串表达式错误? [英] Why do I get an unexpected template string expression error?
问题描述
是否可以在 react-structured-data
JSX内使用地图数组数据( $ {adv_event.title}
)?
Is it possible to use map array data (${adv_event.title}
) inside a react-structured-data
JSX?
我尝试添加反引号,但未成功: name:`$ {adv_event.title}`",
I tried adding backticks with no success: name: "`${adv_event.title}`",
尝试1:
<Generic jsonldtype="event" schema={{
name: "${adv_event.title}",
description: "",
startDate: "YYYY-MM-DDT:HH:MM",
endDate: "YYYY-MM-DDT:HH:MM",
image: "",
}}>
错误:
296:31警告意外的模板字符串表达式字符串中没有模板
296:31 warning Unexpected template string expression no-template-curly-in-string
推荐答案
这是ESLint生成的警告:无模板的字符串中的卷曲
This is an warning generated by ESLint: no-template-curly-in-string
禁止使用常规字符串中的模板文字占位符语法(无字符串模板)
Disallow template literal placeholder syntax in regular strings (no-template-curly-in-string)
ECMAScript 6允许程序员创建包含变量的字符串或使用模板文字而不是字符串的表达式通过在两个之间编写类似 $ {variable}
的表达式进行连接反引号(`).在以下情况下使用错误的引号很容易想要使用模板文字,通过编写"$ {variable}"
并最终使用文字值"$ {variable}"
而不是包含注入的表达式的值.
ECMAScript 6 allows programmers to create strings containing variable
or expressions using template literals, instead of string
concatenation, by writing expressions like ${variable}
between two
backtick quotes (`). It can be easy to use the wrong quotes when
wanting to use template literals, by writing "${variable}"
, and end up
with the literal value "${variable}"
instead of a string containing
the value of the injected expressions.
如果您只想分配该变量,则应执行以下操作:
If you want to just assign that variable you should do this:
<Generic jsonldtype="event" schema={{
name: adv_event.title,
description: "",
startDate: "YYYY-MM-DDT:HH:MM",
endDate: "YYYY-MM-DDT:HH:MM",
image: "",
}}>
您的情况下不需要模板字符串.
A template string is not needed in your case.
