单引号和双引号附加

Question

I am trying to append a single quote and also add double quote, but it shows an error as follows

[ts] ':' expected

  "id": " + ' + jsonObject["school_id"] + ' + "

expected output would be something similar as follows

"id" : "'12345'"

Answer 1

You can't just use ' like that.

If you want to include single quotes in the string, enclose them in a string.

 const jsonObject = {"school_id": "12345"} const obj = {"id": "'" + jsonObject["school_id"] + "'"} console.log(obj); 

Answer 2

You could use template strings to easily create it.

 let jsonObject = {school_id:"1234"} let s = `"id" : "'${jsonObject["school_id"]}'"`; console.log(s) 

Answer 3

You can simply use Template Strings:

const obj = { school_id: "1234" }
const str = `"id" : "'${obj["school_id"]}'"`;

I have not worked much with TypeScript, but looks like they are supported: https://basarat.gitbooks.io/typescript/docs/template-strings.html

Answer 4

please try this to achieve expected result "id" : "'12345'"

 var jsonObject = {school_id: 12345} var a = {"id": '\\'' + jsonObject['school_id'] + '\\''} console.log (a) 

Answer 5

  var school_id = '12345'; school_id = "'"+school_id+"'"; school_id = '"'+school_id+'"'; console.log(school_id); 

You can do like this but make sure you know the use before doing it. don't code blindly.
