Can't parse JSON file with jQuery

I have this JSON:

{
    "solution": {
        "section1": {
            "cell-1": "1",
            "cell-2": "2",
            "cell-3": "3",
            "cell-4": "4",
            "cell-5": "5",
            "cell-6": "6",
            "cell-7": "7",
            "cell-8": "8",
            "cell-9": "9"
        },
        "section2": {
            "cell-1": "1",
            "cell-2": "2",
            "cell-3": "3",
            "cell-4": "4",
            "cell-5": "5",
            "cell-6": "6",
            "cell-7": "7",
            "cell-8": "8",
            "cell-9": "9"
        }
    }
}

My code:

$.getJSON('/static/front/js/src/sudoku/22122016.json', function(data) {
    $.each(data.solution.section1[0], function() {
        $.each(this, function(cell, cellNumber) {
            console.log(cell + ' ' + cellNumber);
        });
    });
});

This code gives me the following error: 

Uncaught TypeError: Cannot use 'in' operator to search for 'length' in 1
at isArrayLike (jquery.js:535)
at Function.each (jquery.js:362)
at String.<anonymous> (main.js:61)
at Function.each (jquery.js:371)
at Object.success (main.js:60)
at fire (jquery.js:3187)
at Object.fireWith [as resolveWith] (jquery.js:3317)
at done (jquery.js:8757)
at XMLHttpRequest.<anonymous> (jquery.js:9123)
in jquery.js:535

I need to access each section separately, so I need to go into each section and then iterate through each key and get its value. How can I achieve this?

Without testing it, I would guess:

$.getJSON('/static/front/js/src/sudoku/22122016.json', function(data) {
    $.each(data.solution, function(sectionName, cells) {
        $.each(cells, function(cellName, cellNumber) {
            console.log(cellName + ' ' + cellNumber);
        });
    });
});

You might want to think about decreasing the indentation level at this point by splitting it up into methods or navigating to the cells directly.

This is the general way to go:

for (var key in a.solution.section1) {
  if (a.solution.section1.hasOwnProperty(key)) {
    console.log(key + " -> " + a.solution.section1[key]);
  }
}

I don't know exactly what you are trying to get, but putting the "[0]" at the end of data.solution.section1 prevents the indexing across the contents of data.solution.section1.

You can just iterate over cells:

$.each(data.solution.section1, function(cell, cellNumber) {
  console.log(cell + ' ' + cellNumber) 
})
