Accessing Array values dynamically

Question

I have Array in this format.

rowData[0] = addRow(aa); 
rowData[1] = addRow(aaa); 
rowData[2] = addRow(aa); 
rowData[3] = addRow(aa); 

addRow is a function which gets this value process.But i don't want to give the Array Index, instead i want to give rowData[i], then put in a loop and access the elements.

rowData holds the an object which addRow returns.

var data = [rowData];
var table = Ti.UI.createTableView({
 data:data
});

Answer 1

Use the Array.push function to store the data:

rowData.push(addRow(aa)); 
rowData.push(addRow(aaa)); 
.
.
.
.
.

Another alternative is:

rowData[rowData.length] = addRow(aa); 
rowData[rowData.length] = addRow(aaa); 
.
.
.
.
.

Use the regular index based iterations to get the data:

for(var i=0; i< rowData.length; i++){
 var curItem = rowData[i];
}

Answer 2

for (var i = 0; i < rowData.length; i++)
{
 rowData[i] = addRow(aa);
}

• Matthew Abbott: You've not been clear with what the difference is between addRow(aa) and addRow(aaa) and how that relates to the array index...

Answer 3

did u mean this?

var rowData = {};
rowData[aa] = addRow(aa);
rowData[aaa] = addRow(aaa); 

for loop access

for(var index in rowData){
 var data = rowData[index]
 ...
}

Answer 4

A loop may not be feasible in your case. This may be an idea: you can rewrite the Array.push prototype method:

Array.prototype._push = Array.prototype.push;
Array.prototype.push = function(val){ this._push(val); return this;};

After which you can chain the push operations:

rowData.push(addRow(aa))
 .push(addRow(aaa)) 
 .push(addRow(aa)) 
 .push(addRow(aa)); 

But actually, it looks like you are mixing arrays with objects. Here's an answer I formulated earlier on that subject.
