rowData = [];
alert(rowData[0]);
gives me [Ti.UI.TableViewRow]
Now how can i remove this element... i have been using rowData.splice(), but i have no idea on what to pass to remove it.
Thanks

In the code you present rowData should be empty, so rowData[0] should be undefined. I suppose something is pushed to rowData in between? Anyway, there are several ways to remove elements from arrays:
- You can remove all elements at once
from an array using
rowData.length = 0. - If you want to remove 1 element, use
the
Array.splicemethod. E.g. removing the first element:rowData.splice(0,1)(means remove 1 element of rowData starting from element 0 (the first element). - If it's only the first element you
want to remove you could also use the
shiftmethod:rowData.shift(). - The last method you can use is
slice:rowData = rowData.slice(1)(means: give me all elements from rowData starting at the first element and assign the result torowData), orrowData.slice(1,4)(means: give me all elements from rowData starting at the first element, ending at the fourth element, and assign the result torowData).

try rowData.splice(0, 1); the first argument indicates the index of item to be removed, the second indicates how many items should be removed
rowData[0].style.display = "none";
