function saveData()
{    
    var rows = $('#deviceTable tr').length;    
    var toSave = "";

    alert(rows);

    for(var i = 0; i < rows; i ++)
    {               
        alert('inside for loop');

        if($("#saveDevName_"+(i)).attr('checked'))
        {

            alert('sving the data');

            toSave+=$("#devName_"+(i)).text()+",";              
        }           
    }       
}

($("#saveDevName_"+(i+1)).attr('checked'))--- is not executed.Hence not checking the status.If statement is not executed {if($("#saveDevName_"+(i)).attr('checked'))} Plz suggest me the right approch.

Replace:

if($("#saveDevName_"+(i)).attr('checked'))

With:

if($("#saveDevName_"+(i)).is(':checked'))

If you're using jQuery 1.6 then you need to either use is(":checked") as suggested by Sarf or use prop instead of attr. As of 1.6 attr("checked") is going to return the attribute value which was set when the page loaded.

Prior to 1.6 I believe using attr("checked") would have worked as you expected.
