Issues with Javascript's JSON.parse functionalityI'm having trouble

As a complete newcomer to the world of JavaScript, I find myself struggling with some issues regarding JSON manipulation. This is my very first attempt at working with it, and I am encountering difficulties in converting my JSON string into an object that can be easily managed within my code. Despite using JSON.parse on my string, my code simply refuses to progress beyond this particular line. Using alerts as a form of debugging tool, I have determined that the code never moves past this instruction:

var toPass = JSON.parse(liveJSON)

The structure of my JSON data is as follows: 

{"request_list": [ {"ip": "10.3.1.12","rtt": 0,"protocol": "NAS","time_asserted": 1428382468,"time_executed": 1428382410}, {"ip": "192.168.0.18","rtt": 1,"protocol": "NAS","time_asserted": 1428382468,"time_executed": 1428382410}, ... ]}

Answer №1

The data in your 'json' is not valid according to standard JSON format, although it may be valid in Javascript.

For example:

... "time_executed": 1428384150,}]}

Having a comma at the end is not allowed in standard JSON.

It is recommended to use a standard JSON library to properly construct your json string.

Here are some examples of invalid JSON but valid in Javascript:

[{},]  
{ {}, }

Answer №2

Make sure to avoid having a trailing , after each "time_executed" value in your JSON file as it will make the JSON invalid.

For validating your JSON, you can use this tool: http://jsonlint.com/

Answer №3

If you need to validate the structure of your JSON, give a try - it's a great tool for that!
