Data-Confirm Modal


Uses Bootstrap's modals
in place of the browser's builtin confirm() API for links generated through Rails'
helpers with the :confirm option.

Any link with the data-confirm attribute will trigger a Bootstrap modal.

HTML in the modal supported, and also the ability to have the user input a
certain value, for extra willingness confirmation (inspired by GitHub's
"delete repository" function).

Installation

Add this line to your application's Gemfile:

gem 'data-confirm-modal'

The library supports Bootstrap 3 and 4. If you are stuck on Bootstrap 2.3, you must
use the bootstrap2 branch:

gem 'data-confirm-modal', github: 'ifad/data-confirm-modal', branch: 'bootstrap2'

Then execute:

$ bundle

And then require the Javascript from your application.js:

//= require data-confirm-modal

Usage

$3

By default, the Gem's Javascript overrides Rails' [data-confirm behaviour][]
for you, with no change required to your code. The modal is applicable to
, and elements by default.

<%= link_to 'Delete', data: {confirm: 'Are you sure?'} %>

The modal's title text can be customized using the data-title attribute.
If data-title is not defined it falls back to the title attribute.

<%= link_to 'Delete', data: {title: 'Are You Sure?'} %>

The modal's 'confirm' button text can be customized using the data-commit
attribute.

<%= link_to 'Delete', data: {confirm: 'Are you sure?', commit: 'Sure!'} %>

Add a data-verify attribute to your input if you want an extra confirmation
from the user. The modal will contain an extra text input, and the user will be
asked to type the verification value before being allowed to proceed.

<%= link_to 'Delete', data: {confirm: 'Are you sure?', verify: 'Foo', verify_text: 'Type "Foo" to confirm'} %>

You can set global setting using dataConfirmModal.setDefaults, for example:

dataConfirmModal.setDefaults({
title: 'Confirm your action',
commit: 'Continue',
cancel: 'Cancel'
});

To restore default settings use dataConfirmModal.restoreDefaults().

$3

Given an element with data-confirm attributes in place, such as

you can then invoke .confirmModal() on it using:

$('#foo').confirmModal();

that'll display the confirmation modal. If the user confirms, then the #foo
link will receive a click event.

$3

Use dataConfirmModal.confirm() passing any of the supported options, and pass
an onConfirm and onCancel callbacks that'll be invoked when the user clicks
the confirm or the cancel buttons.

dataConfirmModal.confirm({
title: 'Are you sure?',
text: 'Really do this?',
commit: 'Yes do it',
cancel: 'Not really',
zIindex: 10099,
onConfirm: function() { alert('confirmed') },
onCancel: function() { alert('cancelled') }
});

$3

The default bootstrap modal options
can be passed either via JavaScript or through data attributes.

$('#foo').confirmModal({backdrop: 'static', keyboard: false});

Background

Spinned off a corporate IFAD application in which
an user did too much damage because the confirm wasn't THAT explicit ... ;-).
