Convert Object to JSON string

问题:

jQuery.parseJSON('{"name":"John"}') converts string representation to object but I want the reverse. Object is to be converted to JSON string I got a link http://www.devcurry.com/2010/03/convert-javascript-object-to-json.html but it need to have json2.js do jQuery has a native method to do this?

回答1:

jQuery does only make some regexp checking before calling the native browser method window.JSON.parse(). If that is not available, it uses eval() or more exactly new Function() to create a Javascript object.

The opposite of JSON.parse() is JSON.stringify() which serializes a Javascript object into a string. jQuery does not have functionality of its own for that, you have to use the browser built-in version or json2.js from http://www.json.org

JSON.stringify() is available in all major browsers, but to be compatible with older browsers you still need that fallback.

回答2:

Also useful is Object.toSource() for debugging purposes, where you want to show the object and its properties for debugging purposes. This is a generic Javascript (not jQuery) function, however it only works in "modern" browsers.

Convert JavaScript object to json data

$("form").submit(function(event){   event.preventDefault();   var formData = $("form").serializeArray(); // Create array of object   var jsonConvertedData = JSON.stringify(formData);  // Convert to json   consol.log(jsonConvertedData); }); 

You can validate json data using http://jsonlint.com

You can use the excellent jquery-Json plugin:

http://code.google.com/p/jquery-json/

Makes it easy to convert to and from Json objects.
