Preface

Here is a case of dynamically adding a table. When you click the Add button, a form can pop up and then add the input content to the table, or you can clear the entire row in the table.

Implementation ideas

First create a table and a form, dynamically add the content entered in the form to the table. There is a close button in the upper right corner of the form page. When clicked, the form page can be closed and the table page can be displayed. In order to make the page beautiful, I put the button to add data in the <tfoot></tfoot> of the table, and added the dynamically generated table data to the <tbody><tbody>. When the Add button is clicked, the table is hidden and the form is displayed. The information to be added is filled in the form, and then the input information is obtained. A row of elements in the table is generated through jQuery, and the obtained values are added. Finally, this row is added to the last row of <tbody><tbody>. When the Add button on the form page is clicked, the form is hidden and the modified changes are displayed. Because the dynamic deletion function is also required, a delete attribute (hyperlink) needs to be added to each row element in the table. When we click Delete, we get the corresponding row and perform the deletion operation.
