Hello I'm trying to call to a function when one make a click on some elements.
I'm doing a form using symfony php framework. Following this: http://symfony.com/doc/current/cookbook/form/form_collections.html#template-modifications
I readed this: https://stackoverflow.com/a/1207393/4386551
But it does not work with a.delete elements, it works for a.add only.
var $collectionHolder;
// setup an "add a tag" link
var $addTagLink = $('<a href="#" class="add">Add a tag</a>');
var $newLinkLi = $('<li></li>').append($addTagLink);
jQuery(document).ready(function() {
// Get the ul that holds the collection of tags
$collectionHolder = $('ul.details');
// add the "add a tag" anchor and li to the tags ul
$collectionHolder.append($newLinkLi);
// count the current form inputs we have (e.g. 2), use that as the new
// index when inserting a new item (e.g. 2)
$collectionHolder.data('index', $collectionHolder.find(':input').length);
$addTagLink.on('click', function(e) {
// prevent the link from creating a "#" on the URL
e.preventDefault();
// add a new tag form (see next code block)
addTagForm($collectionHolder, $newLinkLi);
});
$(".details").on("click", "a.add", function (){alert("HEY");});
$(".details").on("click", "a.delete", function (){alert("HEY");});
});
function addTagForm($collectionHolder, $newLinkLi) {
// Get the data-prototype explained earlier
var prototype = $collectionHolder.data('prototype');
// get the new index
var index = $collectionHolder.data('index');
// Replace '__name__' in the prototype's HTML to
// instead be a number based on how many items we have
var newForm = prototype.replace(/__name__/g, index);
// increase the index with one for the next item
$collectionHolder.data('index', index + 1);
// Display the form in the page in an li, before the "Add a tag" link li
var $newFormLi = $('<li></li>').append(newForm);
$newLinkLi.before($newFormLi);
addTagFormDeleteLink($newFormLi);
}
function addTagFormDeleteLink($tagFormLi) {
var $removeFormA = $('<a href="#" class="delete">delete this tag</a>');
$tagFormLi.append($removeFormA);
$removeFormA.on('click', function(e) {
// prevent the link from creating a "#" on the URL
e.preventDefault();
// remove the li for the tag form
$tagFormLi.remove();
//reload_total();
});
}
what's wrong with a.delete and jquery.on?
