Question

I am using the following JS code to parse a JSON string from a separate JS file:

// extract JSON from a module's JS
var jsonMatch = data.match( /\/\*JSON\[\*\/([\s\S]*?)\/\*\]JSON\*\// );
data = JSON.parse( jsonMatch ? jsonMatch[1] : data );

This is an example of the JS file I extract the JSON string from:

JsonString = /*JSON[*/{"entities":[{"type":"EntityPlayer","x":88,"y":138}]}/*]JSON*/;

This code works just fine, however if the JS file with the JSON string contains carriage returns and isn’t on one complete line then I get a syntax error.

Example:

JsonString = /*JSON[*/{
     "entities":[{
         "type":"EntityPlayer",
         "x":88,
         "y":138}]
     }/*]JSON*/;

Returns the following error:

JSON.parse: unexpected non-whitespace character after JSON data

Any idea how I could modify my parsing to work by either stripping out whitespace or to remove carriage returns and new line spaces?

Answer 1

data = JSON.parse( (jsonMatch ? jsonMatch[1] : data).replace(/\n/g,"") );
