How do I replace single quotes with double quotes in JavaScript?

Answer 1

Need to use regex for this:

var a = "[{'column1':'value0','column2':'value1','column3':'value2'}]";
var b = a.replace(/\'/g, "\"");

Answer 2

Add the g modifier: var b = a.replace(/'/g, '"');

Answer 3

You can use a RegExp with the global flag g and all quotes will replaced:

var b = a.replace(/'/g, '"');

Answer 4

You can use a global qualifier (a trailing g) on a regular expression:

var b = a.replace(/'/g, '"');

Without the global qualifier, the regex (/'/) only matches the first instance of '.

Answer 5

This looks suspiciously like bad JSON, so I suggest using actual array and object literals, then encoding the proper way:

var a = [{'column1':'value0','column2':'value1','column3':'value2'}];
var b = JSON.stringify(a);

Answer 6

var a = "[{'column1':'value0','column2':'value1','column3':'value2'}]";
var b = a.replace(/'/g, '"');
console.log(b);

Edit: Removed \ as there are useless here.
