Three ways to convert a string to JSON format in JS

!--? php function Strtojson (str) { var json = Eval_r (' (' + str + ') '); return JSON; }?> copy code The parentheses on both sides of Str do not forget. Method two, new function form !--? php function Strtojson (str) { var json = (new Function ("return" + str)) (); return JSON; }?> copy code Method Three, using global JSON objects !--? php function Strtojson (str) { return json.parse (str); }?> copy code Currently in IE8 (S)/firefox3.5+/chrome4/safari4/ OPERA10 has implemented this method. The uses json.parse strict adherence to the JSON specification, such as the attribute is enclosed in quotation marks, as follows: var str = ' {name: ' Jack '} '; var obj = Json.parse (str);//--Parse ErrorName is not enclosed in quotation marks, the parsing fails with the exception thrown by all browsers using Json.parse. And the first two ways are fine.
