Question

how can I push data into an array in js if it’s type is likw this… d= [[label, value]]. At first I want to push the label data then the values….
I get the data from an xml file.
If I had only a simple array I used the simple variable.push sintax.
Will varialble[][0].push or variable[][1].push work

Maybe you would be better of using an object,

So you could do

var d  = {
"Label" : "Value"
};

And to add the value you could

d.label = "value";

This might be a more structured approach and easier to understand if your arrays become big. And if you build the JSON valid it’s easy to make a string and parse it back in.

Like var stringD = JSON.stringify(d); var parseD = JSON.parse(stringD);

UPDATE – ARRAY 2D

This is how you could declare it

var items = [[1,2],[3,4],[5,6]];

alert(items[0][0]);

And the alert is reading from it,

To add things to it you would say items[0][0] = "Label" ; items[0][1] = "Value";

If you want to do all the labels then all the values do…

for(var i = 0 ; i < labelssize; i ++)
{
  items[i][0] = labelhere;
}


for(var i = 0 ; i < labelssize; i ++)
{
  items[i][1] = valuehere;
}
