Javascript doesn t handle Strings over multiple lines   You will need to concatenate those   var obj                 name     Raj              age     32             married    false                 You can also use template literals in ES6 and above   See here for the documentation   var obj                  name     Raj               age    32              married    false

The function JSON stringify will turn your json object into a string   var jsonAsString   JSON stringify obj     In case the browser does not implement it  IE6 IE7   use the JSON2 js script  It s safe as it uses the native implementation if it exists

json strings can t have line breaks in them  You d have to make it all one line    key   val   key2   val2  etc        But don t generate JSON strings yourself  There s plenty of libraries that do it for you  the biggest of which is jquery

The way i do it is      var obj   new Object       obj name    Raj      obj age    32     obj married   false     var jsonString  JSON stringify obj     I guess this way can reduce chances for errors
