Js-alert2 NPM | npm.io

js-alert

A simple JavaScript alert manager.

Changes in this fork:

v1.0.9

Added classes to all items to allow customization

v1.0.8

When an alert is created WITHOUT buttons, "clickOutsideDismiss" behavior is ALWAYS true to allow closing the dialog box

v1.0.7

function "clickOutsideDismiss" renamed to "setClickOutsideDismiss" and changed default value to false

v1.0.6

Added function "clickOutsideDismiss" to allow changing clicking outside behavior

v1.0.5

Clicking outside the dialog doesn't dismiss the dialog
Buttons only react when clicked with left button
Solved a legacy dependency problem in package.json
