Does this work? Note that the data is not saved when the user leaves the page, also it's not accessible in any other user's browser.
CODE <button onclick="createSummary()">Create Summary</button> <table id="summary"> <tr> <th>Returned Quantity (kg)</th> <th>Total</th> </tr> </table> <script> function createSummary() { var summary_table=document.getElementById('summary'); var tr=document.createElement("tr"); var quantity_cell=document.createElement("td"); var quantity_field=document.createElement("input"); quantity_field.setAttribute("readyonly", "readonly"); quantity_field.value=document.getElementById('returnedQty').value; var total_cell=document.createElement("td"); var total_field=document.createElement("input"); total_field.setAttribute("readyonly", "readonly"); total_field.value=document.getElementById('total').value; quantity_cell.appendChild(quantity_field); total_cell.appendChild(total_field); tr.appendChild(quantity_cell); tr.appendChild(total_cell); summary_table.appendChild(tr); } </script> |

Code is working, i want to add customer name also in summary. You can just use similar code as the other fields: CODE <table id="summary"> <tr> <th>Customer Name</th> <th>Returned Quantity (kg)</th> <th>Total</th> </tr> </table> var customer_cell=document.createElement("td"); var customer_field=document.createElement("input"); customer_field.setAttribute("readyonly", "readonly"); customer_field.value=document.getElementById('customerName').value; customer_cell.appendChild(customer_field); tr.appendChild(customer_cell); QUOTE Is there any way to save summary data , example csv or excel etc. Not with javascript alone, as far as I know. You'd have to run the page on a server and submit form data to a server-side script (say PHP), which can save the data to other file formats. |
