how to access json field with "-" e.g. 'data-id': 'smth' [duplicate]

How can I access object properties containing special characters?

How do I reference a JavaScript object property with a hyphen in it?

Closed 3 months ago.
I am unable to retrieve a value from a json object when the string has a dash character:
{
"profile-id":1234, "user_id":6789
}
If I try to reference the parsed jsonObj.profile-id it returns ReferenceError: "id" is not defined but jsonObj.user_id will return 6789
I don't have a way to modify the values being returned by the external api call and trying to parse the returned string in order to remove dashes will ruin urls, etc., that are passed as well. Help?

jsonObj.profile-id is a subtraction expression (i.e. jsonObj.profile - id).
To access a key that contains characters that cannot appear in an identifier, use brackets:
jsonObj["profile-id"]

In addition to this answer, note that in Node.js if you access JSON with the array syntax [] all nested JSON keys should follow that syntax
This is the wrong way
json.first.second.third['comment']
and will will give you the 'undefined' error.
This is the correct way
json['first']['second']['third']['comment']

For ansible, and using hyphen, this worked for me:
- name: free-ud-ssd-space-in-percent
debug:
var: clusterInfo.json.content["free-ud-ssd-space-in-percent"]

For anyone trying to apply the accepted solution to HomeAssistant value templates, you must use single quotes if you are nesting in doubles:
value_template: "{{ value_json['internet-computer'].usd }}"

If you are in Linux, try using the following template to print JSON value which contains dashes '-'
jq '.["value-with-dash"]'
It worked for me.

Getting string from another string in Javascript [duplicate]

Parse JSON in JavaScript? [duplicate]
(16 answers)
Closed 2 years ago.
Please note that this is not a json object :) My string is:
{"message":"***error in SAP module:-1***","status":400}
This is not a json object, this is a pure string. I cannot turn it into a json object due to technical limitations.
So, I want to take only the bold string (all the value of "message").
I thought about lastIndexOf, and pick the string between ":" and ","
But I got messed up with the escape characters for the quotes.
How can I achieve it with lastIndexOf? Or in another better way?

If you can't use JSON.parse, I would use a regex to read it. You know you want the string directly following "message":", so I would look for that, then grab everything from there to the next occurrence of "

Validator.js - How to validate Alphanumeric password, in NodeJS? [duplicate]

What do the brackets around the arguments mean when reading documentation for a method? [duplicate]

I am using criso validator.js, of user Input,
but it Eslint is showing error in syntax on this lines
if (!Validator.isAlphanumeric([(data.password,'en-US')])) {
console.log(" Not an alphanumeric");
}
how to properly check user's entered password is Alphanumeric,
I know we can do it using regex but I wanted to do it by using their provided syntax as isAlphanumeric(str [, locale]).
here is their documentation screenshot of code.

The square brackets in the isAlphanumeric(str [, locale]) notation are not related to JavaScript Array literals. Instead, they denote that when calling isAlphanumeric, the first argument str (in your case, data.password) is required, and the second argument locale is optional.
In your case, you do want to pass in a locale. Here is how that would look:
if (!Validator.isAlphanumeric(data.password, 'en-US')) {
console.log("Not an alphanumeric");
}
In technical documentation, square brackets ([]) generally denote that an argument is optional. Tecnhnically this is just a convention (and probably comes from Unix CLI Usage Messages), but in my experience is so widely used that always interpreting square brackets as denoting an optional argument is usually a safe assumption to make.

Babel string interpolation error [duplicate]

Babel error: JSX value should be either an expression or a quoted JSX text

Closed 6 years ago.
I have a bunch of input elements to which I want to assign unique ids.
However, the following string interpolation (i is the mapped element index)
id = `input-add-${i}`
returns
Parsing error: JSX value should be either an expression or a quoted JSX text
I use interpolation successfully elsewhere, so I don't understand what I am doing wrong here.

Ah, my bad. I forgot the curly brackets.
This works
{ id={`input-add-${i}`} }
and this would also work
id={'input-add-' + i}

How to escape double and single quote from JS string [duplicate]

This question already has answers here:
Javascript, Razor and Escape characters. Like apostrophe
(5 answers)
Closed 7 years ago.
I'm assigning the value of JS string variable from server side code.
Like this
var fbShareTitle = "#(ViewBag.LeadTitle as string)";
ViewBag return string value is
A "Fantastic" Lead With 'Qoute'
Now It is giving error in console
SyntaxError: missing ; before statement
I have tried this
var fbShareTitle = ("#(ViewBag.LeadTitle)").replace(/"/g, '\\"');
But now I'm getting this error.
SyntaxError: missing ; before statement
As This string will be shared on fb, So i can't modify string, like replace all " with ' e.t.c.

The reason why your code doesn't work is that Razor will generate the following:
var fbShareTitle = "A "Fantastic" Lead With 'Qoute'";
which is invalid JavaScript. You can't simply fix it by replace, since it's not the problem that your string is bad, it's that your code can't parse - replace never gets to execute. You need to fix it on serverside, where you generate the JavaScript in question, by modifying your Razor code:
var fbShareTitle = #Html.Raw(Json.Encode(ViewBag.LeadTitle as string));
Json will take care of quotes and proper escaping; Raw will make sure you don't get your < and > replaced. Extra benefit from #Html.Raw(Json.Encode(...)) mantra: you can use it to inject any kind of data that can be encoded in JSON, not only strings.
