Adding extra back slash when I fetch data from API-CodePudding

In my application I have to use scientific unit such as m³/h. So that I store that Unicode in my database like m\u00b3/h. But the problem is, when I fetch data from API, it returns this with addition \ like "sign": "m\\u00b3/h". Is there any way to get rid off this issue.

I store the Unicode in DB like this:

When I fetch this, It returns me like this:

And I use this in my UI Like this: Please help.

CodePudding user response：

That extra \ it's just to escape that special character from JSON. If you're using a JSON library, it will escape it automatically.

If not you can use this:

('m\\u00b3/h').replace('\\\\', '\\');

CodePudding user response：

x = 'm\\u00b3/h';
x.replace(/\/\//g, "") // should output m\u00b3/h

Also, if you want to convert unicode to HTML, use this

x = 'm\\u00b3/h';
JSON.parse('"'   x   '"') // Should output 'm³/h'
