Sensible approach. But how is the following issue of using "non
standard" JSON strings solved :
IE8: JSON.parse("{ 'a':1 }") ---> Syntax Error
CHROME: JSON.parse("{ 'a':1 }") ---> OK
FF: JSON.parse("{ 'a':1 }") ---> Syntax Error
OPERA 10.10: JSON.parse("{ 'a':1 }") ---> Undefined variable JSON
SAFARI 4.0.4: JSON.parse("{ 'a':1 }") ---> Syntax Error
I suppose John will reply : "...we do not support non standard
usage ... "
And then I might reply : but CHROME does ?
Ad infinitum ...
Instead I suggest a more productive approach. I suggest JSON.parse not
to be used. (shock?horror!)
The good old Function() just works. Even in IE8 :
var data = "{ 'a':1 }" ; // or the proper syntax '{ "a" : 1 }'
data = (new Function("return " + data))();
Above works in each browser, regardless of the fact that "{ 'a':1 }",
is not a proper JSON syntax. Including IE8, FF and SAFARI where
JSON.parse("{'a':1}") throws error.
Above also works in browsers which have no JSON as a native object, of
course.
A true "cross browser" solution, indeed. It will even lead to a
slightly faster jQuery since one try/catch combo will be removed
(currently in ajax.js, arround line 583)
Now, one might ask why should jQuery 1.4 support "non-standard" JSON
strings?
For the same reasons CHROME does, is my answer to that.
Thanks for reading ... DBJ
