deleteRow fails

Hello,

I got an for loop. With this loop i want to remove rows from my table. But when I start removing it looks like that the indexes are changing of my table. I got a rowCount of 9, when i removed more than 4 rows i goes wrong.

Am i right? And how to solve this problem?

My for loop:

var rows = window.table.data[0].rowCount;
window.table.remove();
for(var i = 0; i < rows; i++)
{
    try {
        window.table.deleteRow(i);
    } catch(e) {
        Ti.API.error(e);
    }
}

Thanks,
Jacob

  • Found a simple solution myself:

    var table = window.table;
var rows = table.data[0].rowCount;

while(rows)
{
    window.table.deleteRow(0); //Always delete the first key
    rows = table.data[0].rowCount;
}

    • Great solution! Also, if you want to delete rows starting from the bottom up:

      var rows = table.data[0].rowCount;
while(rows) {
    table.deleteRow(table.data[0].rowCount-1);
    rows = table.data[0].rowCount;
}

      This is useful if you want to delete certain indices in the table, say, that you have stored in an array and don't want to worry about those indices being offset by deleting a row before the given index.

  • If you want to delete all the rows you can just set the data to nothing:

    window.table.setData(null);
