Further to this, having spent days stepping through javascript, it seems
the following is happening, hopefully my description will not be too off
the mark.
In the example I am using, they use a bit of javascript to 'hook' the ajax
form, as follows:
// Edit a task when the edit link is clicked in the actions dropdown
> $("a.todo-edit").click(function(e) {
> e.preventDefault();
> var todo_id = $(this).closest('ul').attr('id');
> $.getJSON(
> '/edit.task',
> {'id': todo_id},
> function(json) {
> if (json) {
> edit_form = $('#task-form');
> // Set the title to Edit
> edit_form.find('h3').text('Edit Task');
> $.each(json, function(k, v) {
> // Set the value for each field from the returned
> json
> var target=edit_form.find('input[name="' + k +
> '"]')
> target.attr('value', v);
> // Re-initialize the fancy tags input
> if (k === 'tags') {
>
> edit_form.find('input[name="tags"]').importTags(v);
> }
> });
> edit_form.modal('show');
> }
> }
> );
> });
>
(slightly modified to make tracking easier)
Now, that seems to work for setting values that are inputs (ie: standard
text fields), however does not work for selects, so it needs the following
also added:
var target=edit_form.find('select[name="' + k + '"]')
target.attr('value', v);
now, that makes select (dropdown) widgets work, of course it will also need
some even more complex code to support CheckboxChoice widgets, etc.
That all seems VERY manual, just to get a triggering of an ajax form load,
I have to assume this is NOT the right way.
Could anyone PLEASE comment on either why things are this manual, or what
is being done wrong?
Thank you kindly.
