accessing json data ( array of strings) in javascript

Question

My json text is of the form ["string1" , "string2", ...].

How do I convert this to a javascript array and display the values?

Answer 1

Using JSON library https://raw.github.com/douglascrockford/JSON-js/master/json2.js

var array =  JSON.parse('["string1" , "string2", "string3"]');

Or using jQuery

var array =  $.parseJSON('["string1" , "string2", "string3"]');

Or using eval ( Not recommended )

var array =  eval('["string1" , "string2", "string3"]');

Then array[0] , array[1] ...

Answer 2

This is an array, if you open your developer console and try:

["string1" , "string2"][0]
--> "string1"

["string1" , "string2"].length
--> 2

Answer 3

// create array
var myArrayFromJson =  JSON.parse('["string1" , "string2", "string3"]');

// iterate
for (var i=0;i<myArrayFromJson.length;(i=i+1)){
  console.log(myArrayFromJson[i]);
  // ... do things with myArrayFromJson[i] ...  
}
