HOW TO CHECK DATA TABLE IS EMPTY OR NOT ???

bharatmicro

can anybody tell how to check data table is empty or not .. e.g if table is empty then alert("is empty") and if not then alert("not empty")

[code]table.fnSettings().aoData.length[/code] gives You the length of data in table. So if it will be equal to 0 then there is no data.

So You can do this:
[code]
if(table.fnSettings().aoData.length===0) {
alert('no data');
} else {
alert('data exists!');
}[/code]

I'd suggest using fnGetData rather than a private variable from the settings object. fnGetData is a public API and will not change.
