How to parse json data using prototype.js and iterate through it?

Question

I have json array like

var data = '[{ "name": "Violet", "occupation": "character" },{ "name": "orange", "occupation": "color" }]'

How to parse the the data and iterate through it using prototype.js?

Searching for prototypejs parse json lead me to the official Prototype.js documentation. And how to iterate over arrays should be explained in every good JavaScript tutorial, for example: eloquentjavascript.net/chapter4.html. — Felix Kling

There is a function called evalJSON()

var data = '[{ "name": "Violet", "occupation": "character" },{ "name": "orange", "occupation": "color" }]';
data = data.evalJSON();
//for more security:
data = data.evalJSON(true); //sanitizes data before processing it

Then just use for to iterate through the array:

for (var i=0;i<data.length;i++)
{ 
    //do whatever you like with data[i];
}

Or use the prototypeJS .each() function:

data.each(function(el){
    //do whatever you like with el
});

actually you can use the each() method to iterate through the data api.prototypejs.org/language/Enumerable/prototype/each
