Three ways to convert JSON data into valid arrays

Includes global JSON objects and date Tojson methods.

1,eval Way of parsing, I am afraid this is the earliest analytic way.

View sourceprint?1 function Strtojson (str) {

2 var json = eval (' (' + str + ') ');

3 return JSON;

4}

Remember the parenthesis on both sides of the Str.

2,new function form, more bizarre Oh.

View sourceprint?1 function Strtojson (str) {

2 var json = (new function ("return" + str)) ();

3 return JSON;

4}

3, use the global JSON object.

View sourceprint?1 function Strtojson (str) {

2 return Json.parse (str);

Currently IE8 (s)/FIREFOX3.5+/CHROME4/SAFARI4/OPERA10 has implemented this method.

The use of json.parse requires strict adherence to the JSON specification, such as a property that is enclosed in quotes, as follows

View sourceprint?1 var str = ' {name: ' Jack '} ';

2 var obj = json.parse (str); --> Parse Error

Name is not enclosed in quotation marks, and parsing fails with the exception being thrown in all browsers using Json.parse. The first two ways are fine.
