Deleting rows in table Javascript

Question

I'm printing table using function:

   function findL(val){
var i;
//alert(splitted + " " + JSDate);
for(i=0;i<jsData.length; i++)
    {
        if(jsData[i].get_date() == val)
            {

                $('<tr>').append($('<td>').html(jsData[i].get_startT))
                .append($('<td>').html(jsData[i].get_endT))
                .append($('<td>').html(jsData[i].get_prow))
                .append($('<td>').html(jsData[i].get_przedm))
                .append($('<td>').html(jsData[i].get_sala))
                .appendTo('#pzTbody');

            }
        }}

As an argument function takes date from datepicker, and when I pick another date it adds to the previously viewed rows. My problem is that I tried plenty ways to cleaning/deleting old rows before next search.

I tried deleteRow(), .parentNode in loop etc. Anyone know how to delete appended rows?

$("tr").remove() finds all rows and then removes them, you can make the selector more specific yourself — Esailija

@T.J.Crowder I thought about function clean(tbody) that delete whole table body — bohunn

What is this search you talk about? Which rows do you want to delete? Old rows? What is old in this case? — fegemo

From the code I assuem pzTbody is the id of your table. To clean the table body and remove all rows do this:

$("#pzTbody").empty();

If you just want to remove the last row, use this:

$("#pzTbody tr:last-child").remove();
