Add table row in jQuery

Question

What is the best method in jQuery to add an additional row to a table as the last row?

Is this acceptable?

$(\'#myTable\').append(\'

        

Answer 1

In a simple way:

$('#yourTableId').append('<tr><td>your data1</td><td>your data2</td><td>your data3</td></tr>');

Answer 2

I solved it this way.

Using jquery

$('#tab').append($('<tr>')
    .append($('<td>').append("text1"))
    .append($('<td>').append("text2"))
    .append($('<td>').append("text3"))
    .append($('<td>').append("text4"))
  )

Snippet

$('#tab').append($('<tr>')
  .append($('<td>').append("text1"))
  .append($('<td>').append("text2"))
  .append($('<td>').append("text3"))
  .append($('<td>').append("text4"))
)

<table id="tab">
  <tr>
    <th>Firstname</th>
    <th>Lastname</th> 
    <th>Age</th>
    <th>City</th>
  </tr>
  <tr>
    <td>Jill</td>
    <td>Smith</td> 
    <td>50</td>
    <td>New York</td>
  </tr>
</table>

Answer 3

<table id="myTable">
  <tbody>
    <tr>...</tr>
    <tr>...</tr>
  </tbody>
  <tr>...</tr>
</table>

Write with a javascript function

document.getElementById("myTable").insertRow(-1).innerHTML = '<tr>...</tr><tr>...</tr>';

Here is some hacketi hack code. I wanted to maintain a row template in an HTML page. Table rows 0...n are rendered at request time, and this example has one hardcoded row and a simplified template row. The template table is hidden, and the row tag must be within a valid table or browsers may drop it from the DOM tree. Adding a row uses counter+1 identifier, and the current value is maintained in the data attribute. It guarantees each row gets unique URL parameters.

I have run tests on Internet Explorer 8, Internet Explorer 9, Firefox, Chrome, Opera, Nokia Lumia 800, Nokia C7 (with Symbian 3), Android stock and Firefox beta browsers.

<table id="properties">
<tbody>
  <tr>
    <th>Name</th>
    <th>Value</th>
    <th>&nbsp;</th>
  </tr>
  <tr>
    <td nowrap>key1</td>
    <td><input type="text" name="property_key1" value="value1" size="70"/></td>
    <td class="data_item_options">
       <a class="buttonicon" href="javascript:deleteRow()" title="Delete row" onClick="deleteRow(this); return false;"></a>
    </td>
  </tr>
</tbody>
</table>

<table id="properties_rowtemplate" style="display:none" data-counter="0">
<tr>
 <td><input type="text" name="newproperty_name_\${counter}" value="" size="35"/></td>
 <td><input type="text" name="newproperty_value_\${counter}" value="" size="70"/></td>
 <td><a class="buttonicon" href="javascript:deleteRow()" title="Delete row" onClick="deleteRow(this); return false;"></a></td>
</tr>
</table>
<a class="action" href="javascript:addRow()" onclick="addRow('properties'); return false" title="Add new row">Add row</a><br/>
<br/>

- - - - 
// add row to html table, read html from row template
function addRow(sTableId) {
    // find destination and template tables, find first <tr>
    // in template. Wrap inner html around <tr> tags.
    // Keep track of counter to give unique field names.
    var table  = $("#"+sTableId);
    var template = $("#"+sTableId+"_rowtemplate");
    var htmlCode = "<tr>"+template.find("tr:first").html()+"</tr>";
    var id = parseInt(template.data("counter"),10)+1;
    template.data("counter", id);
    htmlCode = htmlCode.replace(/\${counter}/g, id);
    table.find("tbody:last").append(htmlCode);
}

// delete <TR> row, childElem is any element inside row
function deleteRow(childElem) {
    var row = $(childElem).closest("tr"); // find <tr> parent
    row.remove();
}

PS: I give all credits to the jQuery team; they deserve everything. JavaScript programming without jQuery - I don't even want think about that nightmare.

As i have also got a way too add row at last or any specific place so i think i should also share this:

First find out the length or rows:

var r=$("#content_table").length;

and then use below code to add your row:

$("#table_id").eq(r-1).after(row_html);

For the best solution posted here, if there's a nested table on the last row, the new row will be added to the nested table instead of the main table. A quick solution (considering tables with/without tbody and tables with nested tables):

function add_new_row(table, rowcontent) {
    if ($(table).length > 0) {
        if ($(table + ' > tbody').length == 0) $(table).append('<tbody />');
        ($(table + ' > tr').length > 0) ? $(table).children('tbody:last').children('tr:last').append(rowcontent): $(table).children('tbody:last').append(rowcontent);
    }
}

Usage example:

add_new_row('#myTable','<tr><td>my new row</td></tr>');
