How can I convert an Object to a string so that output is something like this:
eg let a = {b: "c"}
Let's assume the above example is our sample Object. Now we can use JSON.stringify(a)
to convert it to string but that outputs,
console.log(a)
-> {"b": "c"}
but I want something like this: {b: "c"}
in the original Object format.
You can try using a Reg-ex, where you replace only the first occurrence of ""
with white space character using $1
in the String.prototype.replace
call:
const a = JSON.stringify({a: "a", b: "b", c: "c"}).replace(/"(\\w+)"\\s*:/g, '$1:'); console.log(a);
您可以尝试javascript-stringify npm软件包。

There is a regex solution that is simpler but it has a shortcoming that is inherent to regex. For some edge cases in complex and nested objects it does not work.
const data = {a: "b", "b": "c", c: {a: "b", "c": "d"}} console.log(stringify(data)) function stringify(obj_from_json){ if(typeof obj_from_json !== "object" || Array.isArray(obj_from_json)){ // not an object, stringify using native function return JSON.stringify(obj_from_json); } // Implements recursive object serialization according to JSON spec // but without quotes around the keys. let props = Object .keys(obj_from_json) .map(key => `${key}:${stringify(obj_from_json[key])}`) .join(","); return `{${props}}`; }
