中国c.n.m安全小组—js 字符串转json(非jquery方法)

1.string转化为json对象 function StringParseToJSON (data) { if (typeof data !== "string" || !data) { return null; } // JSON RegExp var rvalidchars = /^[\],:{}\s]*$/, rvalidescape = /\\(?:["\\\/bfnrt]|u[0-9a-fA-F]{4})/g, rvalidtokens = /"[^"\\\n\r ]*"|true|false|null|-?\d+(?:\.\d*)?(?:[eE][+\-]?\d+)?/g, rvalidbraces = /(?:^|:|,)(?:\s*\[)+/g; // Make sure leading/trailing whitespace is removed (IE can't handle it) data = data.replace(/(^\s+|\s+$)/, ""); // Attempt to parse using the native JSON parser first if (window.JSON && window.JSON.parse) { return window.JSON.parse(data); } // Make sure the incoming data is actual JSON if (rvalidchars.test(data.replace(rvalidescape, "@") .replace(rvalidtokens, "]") .replace(rvalidbraces, ""))) { return (new Function("return " + data))(); } throw new Error("Invalid JSON: " + data); }
