Answer 1

You can use display="table-row"

function toggle(tr_id) {
  var x = document.getElementById(tr_id);
  if (x.style.display === 'none') {
    x.style.display = 'table-row';
  } else {
    x.style.display = 'none';
  }
}

Answer 2

It's because you are displaying the row as block. Try use visibility == "hidden" instead of display

EDIT : Or you can use display = "table-row" as show below. The use visibility == "hidden" will hide the row, but it will still take up the same space as before.

if (x.style.display === "none") {
    x.style.display = "table-row";
} else {
    x.style.display = "none";
}

 function toggle(tr_id) { var x = document.getElementById(tr_id); if (x.style.visibility === "hidden") { x.style.visibility = "visible"; } else { x.style.visibility = "hidden"; } }

 <div class="col-lg-6 col-lg-push-3"> <table class="table table-resposive "> <tr> <td>name</td> <td>address</td> <td>age</td> <td><a onclick="toggle('edit2');" class="btn btn-sm btn-primary">edit</a></td> </tr> <tr id="edit1"> <td><input type="text" ></td> <td><input type="text" ></td> <td><input type="text" ></td> <td><a class="btn btn-sm btn-success">save</a></td> </tr> <tr id="edit2"> <td><input type="text" ></td> <td><input type="text" ></td> <td><input type="text" ></td> <td><a class="btn btn-sm btn-success">save</a></td> </tr> <tr id="edit3"> <td><input type="text" ></td> <td><input type="text" ></td> <td><input type="text" ></td> <td><a class="btn btn-sm btn-success">save</a></td> </tr> </table>

Snippet 2 :

 function toggle(tr_id) { var x = document.getElementById(tr_id); if (x.style.display === "none") { x.style.display = "table-row"; } else { x.style.display = "none"; } }

 <div class="col-lg-6 col-lg-push-3"> <table class="table table-resposive "> <tr> <td>name</td> <td>address</td> <td>age</td> <td><a onclick="toggle('edit2');" class="btn btn-sm btn-primary">edit</a></td> </tr> <tr id="edit1"> <td><input type="text" ></td> <td><input type="text" ></td> <td><input type="text" ></td> <td><a class="btn btn-sm btn-success">save</a></td> </tr> <tr id="edit2"> <td><input type="text" ></td> <td><input type="text" ></td> <td><input type="text" ></td> <td><a class="btn btn-sm btn-success">save</a></td> </tr> <tr id="edit3"> <td><input type="text" ></td> <td><input type="text" ></td> <td><input type="text" ></td> <td><a class="btn btn-sm btn-success">save</a></td> </tr> </table>

Answer 3

set your td css with fixed width

 function toggle(tr_id) { var x = document.getElementById(tr_id); if (x.style.display === "none") { x.style.display = "block"; } else { x.style.display = "none"; } }

 td { width: 140px; display: inline-block; }

 <div class="col-lg-6 col-lg-push-3"> <table class="table table-resposive "> <tr> <td>name</td> <td>address</td> <td>age</td> <td><a onclick="toggle('edit');" class="btn btn-sm btn-primary">edit</a></td> </tr> <tr id="edit"> <td><input type="text"></td> <td><input type="text"></td> <td><input type="text"></td> <td><a class="btn btn-sm btn-success">save</a></td> </tr> </table> </div>

how to make row move to top

 function toggle(tr_id) { var x = document.getElementById(tr_id); if (x.style.visibility === "hidden") { x.style.visibility = "visible"; } else { x.style.visibility = "hidden"; } }

 <div class="col-lg-6 col-lg-push-3"> <table class="table table-resposive "> <tr> <td>name</td> <td>address</td> <td>age</td> <td><a onclick="toggle('edit');" class="btn btn-sm btn-primary">edit</a></td> </tr> <tr id="edit"> <td><input type="text" ></td> <td><input type="text" ></td> <td><input type="text" ></td> <td><a class="btn btn-sm btn-success">save</a></td> </tr> <tr> <td>name</td> <td>address</td> <td>age</td> <td><a onclick="toggle('edit1');" class="btn btn-sm btn-primary">edit</a></td> </tr> <tr id="edit1"> <td><input type="text" ></td> <td><input type="text" ></td> <td><input type="text" ></td> <td><a class="btn btn-sm btn-success">save</a></td> </tr> </table>

Answer 5

the default value of display propery of tr is table-row but not block ,so the design is changed.

You should replace 'block' with 'table-row'

Answer 6

Here's a plain JavaScript way of doing toggle:

 function toggle(_id) { var x = document.getElementById(_id); x.classList.toggle("hide-me"); }

 .hide-me { display: none; }

 <div class="col-lg-6 col-lg-push-3"> <table class="table table-resposive "> <tr> <td>name</td> <td>address</td> <td>age</td> <td><a onclick="toggle('edit');" class="btn btn-sm btn-primary">edit</a></td> </tr> <tr id="edit"> <td><input type="text"></td> <td><input type="text"></td> <td><input type="text"></td> <td><a class="btn btn-sm btn-success">save</a></td> </tr> </table> </div>
