JavaScript build nested array from string values

Question

From my data source I am getting values like;

USA        |Arizona
USA        |Florida
UK         |England |Northamptonshire
UK         |England |Derbyshire
U         


        

Answer 1

Turn it to JSON:

var str = '"USA|Arizona","USA|Florida","UK|LonelyIsland","UK|England|Northamptonshire","UK|England|Derbyshire","UK|Wales|Powys","UK|England|London|Soho","Switzerland|Lucern';

var jsonStr = "[[" + str.replace(/,/g,'],[') + "\"]]";
jsonStr = jsonStr.replace(/\|/g,'","');
var nested = JSON.parse(jsonStr);

Then play with parents and children.

function findObject(array, key, value) {
    for (var i=0; i0)
        obje = obje.addChild(arr);
}


var finArr = [];
for(i=0; i0)
                recc.addChildren(nested[i]);
        finArr.push(recc);        
    }
}

console.log('------------------------------------------')
console.log(JSON.stringify(finArr));
console.log('--------------------The End---------------')
