execute a javascript code inside a json object?

Question

is there away?

so something like:

{ key1 : "val1", key2: "val2", some_code: "document.getElementById("someid").innerHTML='test';" }

So some_code would be executed without any user intervention?

Answer 1

No.

First of all, your example isn't valid JSON. Try it out at JSON validator.

Second of all, JSON is a data exchange standard and when properly parsed, any text that inside of it that is some code will not be executed.

Read on JSON security issues.

Rule of thumb: don't use JavaScript eval function, rather use a ready made parser such as Douglas Crockford's JSON evaluator.
