Check out sfJqueryReloadedPlugin. It contains jQuery versions of the
classic Symfony JavaScript helpers. If some of the helpers that have
been removed in Symfony 1.3 are not reimplemented in
sfJqueryReloadedPlugin, feel free to copy or reimplement them there
(with a jq_ prefix) and/or bring it up with the devs (including me).
For compatibility reasons the jQuery versions of the helpers have a
jq_ prefix, so it's safe to reimplement things that also exist in the
core in 1.2, and change the other helpers to utilize those
reimplemented versions... but please code them correctly (:
Having said all that, I tend to agree that jQuery is so expressive and
concise that the helpers don't really add much elegance. I use the
helpers less and less myself.
Some cases are complex enough that I suppose helpers still make sense.
remote_form_tag looks something like this if you write it directly in
jQuery:
<script>
$('form').submit(function() {
$.post(<?php echo json_encode(url_for('mymodule/myaction')) ?>,
$(this).serialize(),
function(data) {
$('#mycontainer').html(data);
}
);
}
</script>
That's pretty darn elegant, but it's such a common pattern that the
helper is still worth it to save typing and avoid bugs.
The most important modern PHP feature for javascript interaction,
IMHO, is the json_encode method. People use it mostly for AJAX
responses but it is also fantastic for emitting a parameter to a
javascript function (string, number, array, hash, - json_encode will
escape it properly):
callAFunction(<?php echo json_encode($myvar) ?>);
Or setting variables:
var mydata = <?php json_encode($myBigComplexHashOfArraysNoProblem) ?>;
Others will tell you that your JavaScript should be entirely separate
in clean .js files that pick up on IDs and class names in the HTML and
do something brilliant with them - the progressive enhancement
philosophy. I think they are mostly right, but there IS a need
sometimes to kick some javascript data and maybe even code out there
on the fly in the context where you have the relevant variables at
hand, IMHO.
