Three ways to convert a string to JSON in JS

1, the Eval method analysis, I am afraid this is the earliest analytic way. As follows:

functionvar json = eval (' (' + str + ') 'return '

2, new function form, more strange oh. As follows:

functionvar json = (new function ("return" +return

3. Use the global JSON object as follows:

functionreturn

At present IE8 (S)/FIREFOX3.5+/CHROME4/SAFARI4/OPERA10 has implemented the method, the following is part of the information: http://blogs.msdn.com/ie/archive/2008/09/10/ Native-json-in-ie8.aspx Https://developer.mozilla.org/en/Using_JSON_in_Firefox
The use of json.parse requires strict adherence to the JSON specification, as attributes are enclosed in quotation marks, as follows:

var str = ' {name: ' Jack '} 'var//
