如何在JavaScript中的单独数组中隐藏JSON数据？

Question

My JSON data has following format :

[{"Name":"A","Id":"1"},{"Name":"B","Id":"2"},{"Name":"C","Id":"3"}]

How covert this into two separate arrays as Name[] and Id[] using JavaScript ? I need the data in the following manner:

Name[0] should be : "A"
Name[1] should be : "B" and so on ... 

Answer 1

this should work, jsonArray is your JSON

var name = [], ids = [];
jsonArray.forEach(function(item){
  name.push(item.Name);
  ids.push(item.Id);
}

Answer 2

var data = [{"Name":"A","Id":"1"},{"Name":"B","Id":"2"},{"Name":"C","Id":"3"}];

var result = {};
for (var i=0; i<data.length; i++) {
    for (var key in data[i]) {
        var item = data[i][key];
        if (key in result)
            result[key].push(item);
        else
            result[key] = [item];
    }
}

result.Name // ["A","B","C"]
result.Id // ["1","2","3"]

You could use miso project if you are handling a lot of data with different source.

var ds = new Miso.Dataset({
  data: [ 
    { one : 1, two : 4, three : 7 },
    { one : 2, two : 5, three : 8 }
  ]
}).fetch({
  success: function() {
    log( this.column('one').data );
  }
});
