The conversion of object to string in JS

When using JSON2. JS file Json.parse (data) method, encountered a problem:

throw new SyntaxError (' Json.parse ');

To inquire about the information, the general meaning is as follows:

The Json.parse method throws an SyntaxError exception when it encounters a non-resolvable string.

namely: Json.parse (text, Reviver), this method parses a JSON text to produce an object or array. T can throw a SyntaxError exception.

So, here is a summary of the JS object and string conversion, because this involves browser compatibility issues.

how the 1:jquery plugin supports conversion
The code is as follows:
$.parsejson (JSONSTR); Jquery.parsejson (JSONSTR), you can convert a JSON string into a JSON object

In turn, use the Serialize series method: for example: var fields = $ ("SELECT,: Radio"). Serializearray ();

2: Browser-supported conversion mode (FIREFOX,CHROME,OPERA,SAFARI,IE9,IE8) and other browsers
The code is as follows:
Json.parse (JSONSTR); You can convert a JSON string into a JSON object
Json.stringify (Jsonobj); You can convert a JSON object to a JSON string

Note: IE8 (compatibility mode), IE7 and IE6 do not have JSON objects and need to introduce json.js or json2.js.

3:javascript Supported conversion modes
Eval (' (' + jsonstr + ') '); You can convert a JSON string to a JSON object, noting that you need to wrap a pair of parentheses outside the JSON character
Note: IE8 (compatibility mode), IE7 and IE6 can also use eval () to convert strings to JSON objects, but these methods are not recommended, which is unsafe for eval to execute an expression in a JSON string.

4:json Official way of conversion
http://www.json.org/, provides a json.js so that IE8 (compatibility mode), IE7 and IE6 can support JSON objects as well as their stringify () and Parse () methods;
