Question

I have the following javascript which I need to make dynamic.

data.addRows(2);
data.setValue(0, 0, 'name goes here');
data.setValue(0, 1, value 1 goes here); 
data.setValue(0, 2, value 2 goes here); 
data.setValue(1, 0, 'name goes here');
data.setValue(1, 1, value 1 goes here); 
data.setValue(1, 2, value 2 goes here); 

I guess a loop is the best way to go forward:

I have come up with the following json structure:

[ 
    {"User1":{"value1": 50.00,"value2": "100"}}, 
    {"User2":{"value1": 10.00,"value2": "20"}}, 
    {"User3":{"value1": 10.00,"value2": "20"}}, 
    {"User4":{"value1": 10.00,"value2": "20"}}, 
    {"User5":{"value1": 20.00,"value2": "40"}} 
] 

I think this structure needs improving. Can someone please suggest a better structure to make it very easy for me to extract the data I want to extract from this?

Answer 1

var dataset = [
  {uid: 'user1', value1: 50.00, value2: 100},
  {uid: 'user2', value1: 10.00, value2: 20}, 
];

That way you can do data.length to figure out how many values you have and you can loop a bit easier. For example:

for(i = 0; i < dataset.length; i++) {
   console.log(data[i].uid);
}

Using your example:

data.addRows(2); 
var l = dataset.length, i, x = 0, y = 0;
for(i = 0; i < l; i++) {
  data.setValue(y, x, dataset[i].uid); x++;
  data.setValue(y, x, dataset[i].value1); x++;
  data.setValue(y, x, dataset[i].value2); x=0;
  y++;
}
