如何从json对象中删除双引号

Question

My JSON object looks like below

"{'EN':{'APP_TITLE':'TESTHEADING'}}"

Can some help me on removing the double quotes at first position and last position I tried with regex but not able to remove it.

Answer 1

Use .substring() like below:

 let input = "\\"{'EN':{'APP_TITLE':'TESTHEADING'}}\\""; let output = input.substring(1, input.length - 1); console.log(`Input: ${input} \\nOutput: ${output}`);

Answer 2

• To remove the double quotes at the beginning and end, you can use substring . It take a start index (here 1 skipping the first character) and an end (here str.length - 1 skipping the last)
• To have a valid JSON string you also need to replace the single quotes with double quotes . To do that you can use a regex with the function replace . The g option replace all occurences of your target character ' => "
• To load this as an object (for further processing) in JavaScript, use JSON.parse . This will convert your JSON string into an actual object.

Combining the 3 steps will give you something like this

 const str = "\\"{'EN':{'APP_TITLE':'TESTHEADING'}}\\""; const withoutQuotes = str .substring(1, str.length - 1) .replace(/'/g, '"'); const actualJSON = JSON.parse(withoutQuotes); console.log(actualJSON);
