单击表格行删除按钮后删除表格行

Question

Solution can use jQuery or be plain JavaScript.

I want to remove a table row after user has clicked the corresponding button contained in the table row cell so for example:

<script>
function SomeDeleteRowFunction() {
 //no clue what to put here?
}
</script>

<table>
   <tr>
       <td><input type="button" value="Delete Row" onclick="SomeDeleteRowFunction()"></td>
   </tr>
   <tr>
       <td><input type="button" value="Delete Row" onclick="SomeDeleteRowFunction()"></td>
   </tr>
   <tr>
       <td><input type="button" value="Delete Row" onclick="SomeDeleteRowFunction()"></td>
   </tr>
</table>

Answer 1

You can use jQuery click instead of using onclick attribute, Try the following:

$('table').on('click', 'input[type="button"]', function(e){
   $(this).closest('tr').remove()
})

Demo

Answer 2

you can do it like this:

<script>
    function SomeDeleteRowFunction(o) {
     //no clue what to put here?
     var p=o.parentNode.parentNode;
         p.parentNode.removeChild(p);
    }
    </script>

    <table>
       <tr>
           <td><input type="button" value="Delete Row" onclick="SomeDeleteRowFunction(this)"></td>
       </tr>
       <tr>
           <td><input type="button" value="Delete Row" onclick="SomeDeleteRowFunction(this)"></td>
       </tr>
       <tr>
           <td><input type="button" value="Delete Row" onclick="SomeDeleteRowFunction(this)"></td>
       </tr>
    </table>

Answer 3

Using pure Javascript:

Don't need to pass this to the SomeDeleteRowFunction() :

<td><input type="button" value="Delete Row" onclick="SomeDeleteRowFunction()"></td>

The onclick function:

function SomeDeleteRowFunction() {
      // event.target will be the input element.
      var td = event.target.parentNode; 
      var tr = td.parentNode; // the row to be removed
      tr.parentNode.removeChild(tr);
}

Answer 4

Following solution is working fine.

HTML:

<table>
  <tr>
    <td>
      <input type="button" value="Delete Row" onclick="SomeDeleteRowFunction(this);">
    </td>
  </tr>
  <tr>
    <td>
      <input type="button" value="Delete Row" onclick="SomeDeleteRowFunction(this);">
    </td>
  </tr>
  <tr>
    <td>
      <input type="button" value="Delete Row" onclick="SomeDeleteRowFunction(this);">
    </td>
  </tr>
</table>

JQuery:

function SomeDeleteRowFunction(btndel) {
    if (typeof(btndel) == "object") {
        $(btndel).closest("tr").remove();
    } else {
        return false;
    }
}

Answer 5

As @gaurang171 mentioned, we can use .closest() which will return the first ancestor, or the closest to our delete button, and use .remove() to remove it.

This is how we can implement it using jQuery click event instead of using JavaScript onclick.

 $(document).ready(function(){ $("#myTable").on('click','.btnDelete',function(){ $(this).closest('tr').remove(); }); });

 table{ width: 100%; border-collapse: collapse; } table td{ border: 1px solid black; } button:hover{ cursor: pointer; }

 <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <table id="myTable"> <tr> <th>ID</th> <th >Name</th> <th>Age</th> <th width="1%"></th> </tr> <tr> <td >SSS-001</td> <td >Ben</td> <td >25</td> <td><button type='button' class='btnDelete'>x</button></td> </tr> <tr> <td >SSS-002</td> <td >Anderson</td> <td >47</td> <td><button type='button' class='btnDelete'>x</button></td> </tr> <tr> <td >SSS-003</td> <td >Rocky</td> <td >32</td> <td><button type='button' class='btnDelete'>x</button></td> </tr> <tr> <td >SSS-004</td> <td >Lee</td> <td >15</td> <td><button type='button' class='btnDelete'>x</button></td> </tr>
