Remove quote from outside Json object in js

Question

var obj = '{'include':true,'fn':'1-12'}'

I want to read fn value. how to remove single quotes which are present outside the {}?

Answer 1

try this

remove double quotes from a String

like this:

var str = 'remove "foo" delimiting double quotes';
console.log(str.replace(/"([^"]+(?="))"/g, '$1'));
//logs remove foo delimiting quotes
str = 'remove only "foo" delimiting "';//note trailing " at the end
console.log(str.replace(/"([^"]+(?="))"/g, '$1'));
//logs remove only foo delimiting "<-- trailing double quote is not removed

Answer 2

Replace single quotes ' with double quotes " and then use JSON.parse() method to get a JSON object. The following works:

//var obj = '{'include':true,'fn':'1-12'}'; -- This assignment is invalid
var obj = "{'include':true,'fn':'1-12'}"; //Assuming double quotes outside
var obj1 = obj.replace(/'/g, "\""); //Replace single quotes with double quotes
console.log(typeof obj1); // string

var myjsonobj = JSON.parse(obj1); //convert to JSON

//myjsonobj is now a proper JSON object

console.log(myjsonobj); // Object {include: true, fn: "1-12"}
console.log(typeof myjsonobj); // object
console.log(myjsonobj.fn); // 1-12

Answer 3

Here it works for you

var regex = /[\']/g;
var obj = "'{'include':true,'fn':'1-12'}'";
obj = obj.replace(regex,"");
console.log(obj);

Answer 4

First of all this isn't valid JSON or javascript object

var obj = '{'include':true,'fn':'1-12'}'

Fix your object, then you can use eval() like this:

var obj = JSON.parse('{"include":true,"fn":"1-12"}');
var fn = eval(obj.fn);
