Question

I am trying to convert this HTML table:

Code:

<table id="students" border="1">
    <thead>
        <tr>
            <th>Name</th>
            <th>Age</th>
            <th>Grade</th>
        </tr>
    </thead>
    <tbody>
        <tr class="student">
            <td>Oscar</td>
            <td>23</td>
            <td>16.5</td>        
        </tr>
        <tr class="student">
            <td>Antonio</td>
            <td>32</td>
            <td>14</td>        
        </tr>
        <tr class="student">
            <td>Jessica</td>
            <td>21</td>
            <td>19</td>        
        </tr>
    </tbody>
</table>​​​​​​

Into a javascript object using jQuery:

var tbl = $('table#students tr').map(function() {
  return $(this).find('td').map(function() {
    return $(this).text();
  }).get();
}).get();

The above code will output the following array:

["Oscar", "23", "16.5", "Antonio", "32", "14", "Jessica", "21", "19"]

Everything is good at this point but how can I do if I want the javascript objects inside the array to have the following structure:

[{id:1, name: "Oscar", age: 23, grade: 16.5}, {id:2, name: "Antonio", age: 32, grade: 14}, {id:3, name: "Jessica", age: 21, grade: 19}]

Just to be more specific…

• The id is obtained from the tr
• The name, age and grade values are obtained from each row

I made this jsfiddle to test:

Answer 1

var tbl = $('#students tr:has(td)').map(function(i, v) {
    var $td =  $('td', this);
        return {
                 id: ++i,
                 name: $td.eq(0).text(),
                 age: $td.eq(1).text(),
                 grade: $td.eq(2).text()               
               }
}).get();
