json - regular expression add double quotes around values and keys in javascript

Question

i need a valid JSON format to request ES. i have a string like

{ 
time:  { 
          from:now-60d,
          mode:quick,
          to:now } 
}

but when i try to use JSON.parse i got error because my string should be like

 { 
time:  { 
          "from":"now-60d",
          "mode":"quick",
          "to":"now" } 
}

so my question, there is any solution to add double quotes around keys and values of my string ?

thanx

Answer 1

maybe you can use :

str.replace(/([a-zA-Z0-9-]+):([a-zA-Z0-9-]+)/g, ""$1":"$2"");

Here is

Note

In the group [a-zA-Z0-9-] of characters i use alphabetical digits and a -, maybe you need other so you can use another one
