- How can I calculate duration in seconds for more rows from two times?
- <!--Time calculation-->

- $(document).ready(function() {
- //this calculates values automatically
- sum();
- $("#start_time, #end_time").on("keydown keyup", function() {
- sum();
- });
- });
- function sum() {
- var start_time = document.getElementById('start_time').value;
- var end_time = document.getElementById('end_time').value;
- var result = parseInt(end_time) - parseInt(start_time);
- if (!isNaN(result)) {
- document.getElementById('sum').value = result;
- }
- }
- </script>
- <!--add row-->
- <script>
- function addRow(tableID) {
- var table = document.getElementById(tableID);
- var rowCount = table.rows.length;
- var row = table.insertRow(rowCount);
- var colCount = table.rows[0].cells.length;
- row.id = 'row_'+rowCount;
- for (var i = 0; i < colCount; i++) {
- var newcell = row.insertCell(i);
- newcell.outerHTML = table.rows[0].cells[i].outerHTML;
- }
- }
- function deleteRow(tableID) {
- var table = document.getElementById(tableID);
- var rowCount = table.rows.length;
- for (var i = 0; i < rowCount; i++) {
- var row = table.rows[i];
- var chkbox = row.cells[0].childNodes[0];
- if (null !== chkbox && true === chkbox.checked) {
- if (rowCount <= 1) { // limit the user from removing all the fields
- alert("Cannot Remove all the Passenger.");
- break;
- }
- table.deleteRow(i);
- rowCount--;
- i--;
- }
- }
- }
