This is on Drupal 8.6, PHP 7.2, Theme is based on Bootstrap.
The scenario is, I want to display a dialog box with a subscription form in the home page. The dialog box will be loaded automatically when page load, not by click any link. I see there are lot of examples there in the net, but all related to by clicking a link, modal will display. But I want to load it without any click.
I partially successful by using BootstrapDialog, but ajax is not working on form submit button. What I did, I attach a js file in the front page, with the code below. It shows the Modal Dialog box, and I tuned a page--newsletter--subscribe.html.twig, its working But submit button not working not ajax is working.
BootstrapDialog.show({
title: 'Subscribe To Newsletter',
message: jQuery('<div></div>').load('/newsletter/subscribe'),
closable: false,
draggable: true,
closeByBackdrop: false,
closeByKeyboard: false,
buttons: [{
label: 'Close',
action: function(dialogRef){
dialogRef.close();
}
}]
});
I saw there is an example in code node.preview.js file like this:
var $previewDialog = $('<div>' + Drupal.theme('nodePreviewModal') + '</div>').appendTo('body');
Drupal.dialog($previewDialog, {
title: Drupal.t('Leave preview?'),
buttons: [{
text: Drupal.t('Cancel'),
click: function click() {
$(this).dialog('close');
}
}, {
text: Drupal.t('Leave preview'),
click: function click() {
window.top.location.href = event.target.href;
}
}]
}).showModal();
But I never able to make it working in my custom module.
If some one can help on this, will be really great!
Update: I just tried to put a link manually in the template and tried to open the dialog, but it gives me some error:
<a href="/newsletter/registration" class="use-ajax " data-dialog-type="modal">Show Dialog</a>
The error is as follows:
dialog.js?v=8.6.4:35 Uncaught TypeError: $element.dialog is not a function

It seems some of the library is not loaded. Here is my global attachement:
dependencies:
- core/jquery
- core/jquery.ui
- core/drupal.ajax
- core/drupal
- core/drupalSettings
- core/drupal.dialog
- core/drupal.dialog.ajax
- core/jquery.form
- core/jquery.once
- core/modernizr
.loadand expect that to work. You need to have something return a renderable form or a fully rendered form only,Its loading using router ymlp.route.registration: path: '/newsletter/registration' defaults: _form: '\Drupal\ymlp\Form\YmlpRegistrationForm' _title: 'Newsletter Registration' requirements: _permission: 'access content'$('element').on('click', function), you can use$('element').click()in your.load()or.ready()for example. You can let jQuery click for the user.
