I've been tinkering with this for a long long time.
I would like to hijack the default JS confirm dialog with something I rolled myself. I'd like to use a completely custom layout (the bootstrap(from twitter) dialog panel).
What I have doesn't work. It show up nicely and I can click the buttons and it'll dissapear. The documentation says that you should return true in case of Ok and false in case of a Cancel. This is very cute and all but it doesn't work. It looks like I need a callback or a reference to the object that originally called the function. Even the latter isn't possible since $.rails.confirm only passes in the message.
(The first answer from this question is pretty interesting. I need a way to make it modal so it waits for the return of the custom dialog.)
So could somebody please point me in the right direction? I feel like I'm going to slap something. Hard!! jQuery UI is only an option of I can make my dialog look exactly like the one I currently have.
Here is what I have:
This is placed in my application.erb
<div id="modal-confirm" class="modal">
<div class="modal-header">
<h3>Are you sure?</h3>
<a href="#" class="close">×</a>
</div>
<div class="modal-body">
<p>{{VALUE}}</p>
</div>
<div class="modal-footer">
<a id="modal-accept" href="#" class="btn primary">OK</a>
<a id="modal-cancel" href="#" class="btn secondary">Cancel</a>
</div>
</div>
javascript.js:
function bootStrapConfirmDialog(message) {
// get a handle on the modal div (that's already present in the layout).
d = $("#modal-confirm");
// replace the message in the dialog with the current message variable.
$("#modal-confirm div.modal-body p").html(message);
// offset the dialog so it's nice and centered. we like that ;)
// d.offset({ top: 400, left: (document.width - d.width) / 2 });
d.center();
// show the dialog.
d.toggle(true);
console.log("popped open");
}
$(document).ready(function(){
// jquery support
$.fn.extend({
center: function () {
return this.each(function() {
var top = ($(window).height() - $(this).outerHeight()) / 2;
var left = ($(window).width() - $(this).outerWidth()) / 2;
$(this).css({position:'absolute', margin:0, top: (top > 0 ? top : 0)+'px', left: (left > 0 ? left : 0)+'px'});
});
}
});
// modal stuff
$("#modal-confirm").toggle(false);
// wire up cancel and x button.
$("#modal-confirm #modal-cancel, #modal-confirm a.close").click(function (e) {
d.toggle(false);
console.log("clicked cancel");
return false;
});
// wire up OK button.
$("#modal-confirm #modal-accept").click(function (e) {
d.toggle(false);
console.log("clicked accept");
return true;
});
// wire up our own custom confirm dialog.
$.rails.confirm = function(message) { console.log("start intercept"); return bootStrapConfirmDialog(message); };
});
and then finally in my view:
<%= link_to 'delete customer', customer_path(@customer), :class => 'btn danger', :method => :delete, :confirm => "Are you sure you would like to delete '#{@customer.name}'?" %>
@ 23:46 GMT
Ok, I figured out a way ... and it isn't pretty. I basically extended jquery-rjs in a way that the actual element is passed along to the $.rails.confirm method. That way I at least know what should happen if the OK button is pressed in the modal. So here is the new snazzy code.
My new application.js. Works like a charm. But I'm a little disturbed at how many things I had to override. I probably broke something and I don't even know about it (rails.formSubmitSelector and/or rails.formInputClickSelector). So if you have a better solution ... give :D thx!
function bootStrapConfirmModal(message, element) {
// get a handle on the modal div (that's already present in the layout).
d = $("#modal-confirm");
// replace the message in the dialog with the current message variable.
$("#modal-confirm div.modal-body p").html(message);
// offset the dialog so it's nice and centered. we like that ;)
d.center();
// wire up cancel and x button.
$("#modal-confirm #modal-cancel, #modal-confirm a.close").click(function (e) {
d.toggle(false);
return false;
});
// wire up OK button.
$("#modal-confirm #modal-accept").click(function (e) {
d.toggle(false);
// actually handle the element. This has to happen here since it isn't an *actual* modal dialog.
// It uses the element to continue proper execution.
$.rails.handleLink(element);
return false;
});
// show the dialog.
d.toggle(true);
};
$(document).ready(function(){
// jquery support
$.fn.extend({
center: function () {
return this.each(function() {
var top = ($(window).height() - $(this).outerHeight()) / 2;
var left = ($(window).width() - $(this).outerWidth()) / 2;
$(this).css({position:'absolute', margin:0, top: (top > 0 ? top : 0)+'px', left: (left > 0 ? left : 0)+'px'});
});
}
});
// modal stuff
$("#modal-confirm").toggle(false);
// $.rails overrides.
// wire up our own custom confirm dialog. Also extend the function to take an element.
$.rails.confirm = function(message, element) { return bootStrapConfirmModal(message, element); };
$.rails.allowAction = function(element) {
var message = element.data('confirm'),
answer = false, callback;
if (!message) { return true; }
if ($.rails.fire(element, 'confirm')) {
// le extension.
answer = $.rails.confirm(message, element);
callback = $.rails.fire(element, 'confirm:complete', [answer]);
}
return answer && callback;
};
$.rails.handleLink = function(link) {
if (link.data('remote') !== undefined) {
$.rails.handleRemote(link);
} else if (link.data('method')) {
$.rails.handleMethod(link);
}
return false;
};
});
