Question: What is the Security and JSON Parser?Answer: Security and JSON Parser to understand by below examples// Include http://www.json.org/json.js var myObject = myJSONtext.parseJSON(); • eval() can compile and execute any JavaScript program, so there can be security issues (cross-site scripting) Use eval() when the source can be trusted • When security is a concern - the source cannot be trusted -, it is better to use a JSON parser A JSON parser will only recognize JSON text and so is much safer Object to Text Conversion var myJSONText = myObject.toJSONString(); • You can convert JSON object into JSON text • JSON does not support cyclic data structure Do not give cyclical structures to the JSON stringifier |
