Jquery – Drupal CCK add another item callback

ajaxcckdrupaljquery

I'm trying to get the last field item to focus when doing a 'add another item' on a CCK multiple value field.

Here's my code:

 $("#node-form table.content-multiple-table tr.draggable input[type='text']").live("keydown", function (e) {
  if (e.which == 13) {
   $(this).closest("table.content-multiple-table").siblings("div.content-add-more").find("input.form-submit").mousedown();
   $(this).closest("tr.draggable").next().find("input[type='text']").trigger("focus");
   return false;
  }
 });

Clearly this doesn't work because the field is created on AHAH response. 🙁

Anyone know how to hook into the response to focus the last field? Thanks.

You should use Drupal.behaviors and Drupal should manage attaching the behaviors for you. Modules should re run these after modifying the DOM (including AHAH requests).

In your case you will probably want to add two behaviors, one to the button to flag that it was pressed and another on the last field to focus if the flag is set (and unset the flag).

The same as other answers, in a jQuery fashion:

$.each(selectValues, function(key, value) {   
     $('#mySelect')
         .append($("<option></option>")
                    .attr("value", key)
                    .text(value)); 
});

Javascript – Add table row in jQuery

The approach you suggest is not guaranteed to give you the result you're looking for - what if you had a tbody for example:

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

You would end up with the following:

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

I would therefore recommend this approach instead:

$('#myTable tr:last').after('<tr>...</tr><tr>...</tr>');

You can include anything within the after() method as long as it's valid HTML, including multiple rows as per the example above.

Update: Revisiting this answer following recent activity with this question. eyelidlessness makes a good comment that there will always be a tbody in the DOM; this is true, but only if there is at least one row. If you have no rows, there will be no tbody unless you have specified one yourself.

DaRKoN_ suggests appending to the tbody rather than adding content after the last tr. This gets around the issue of having no rows, but still isn't bulletproof as you could theoretically have multiple tbody elements and the row would get added to each of them.

Weighing everything up, I'm not sure there is a single one-line solution that accounts for every single possible scenario. You will need to make sure the jQuery code tallies with your markup.

I think the safest solution is probably to ensure your table always includes at least one tbody in your markup, even if it has no rows. On this basis, you can use the following which will work however many rows you have (and also account for multiple tbody elements):

$('#myTable > tbody:last-child').append('<tr>...</tr><tr>...</tr>');
