Boot your alerts in the … with bootAlert

Unfortunately, due to the sudden illness and ultimate passing of a family member in the fall, it has been quite a while since I last blogged.  Hopefully, this post finds me getting back on the blogging horse to contribute some content to the Xpages/Domino community and bring some ideas I had been kicking around to fruition.

Today I am releasing bootAlert, a simple XPages custom control that allows developers to add configurable, reusable Bootstrap alerts to their apps without having to add any additional plugins.  You should already be using Bootstrap/jQuery in your application in order to use this custom control.

For the past few months, in working on our application migration project, I built a configurable Bootstrap alert custom control.  I found myself continuing to add features as different needs arose.  So, I thought I would release it to the community.

Why bootAlert?

  • bootAlert can be triggered from both server and client-side Javascript
  • bootAlert can use Font Awesome icons
  • bootAlert can be turned into a Growl-like message on-the-fly
  • bootAlert is dynamically configurable – one action may require the 'success' class and another may require a 'warning' or 'danger' notification.  One control can be used to display all three.
  • bootAlert can be customized with css
  • Add as many bootAlert controls to your page as you want
bootAlert with view.postScript

bootAlert can be triggered from server-side js with view.postScript()

bootAlert let's you add Bootstrap Growl messages

Demo

I plan on submitting this as an OpenNtf project, but for now you can find a demo, as well as download bootAlert here

Getting Started

Getting started with bootAlert is easy.  Simply:

  • Download the demo database
  • Copy the custom control and script library into your application (or copy the contents of the script library into your existsing client-side script library)
  • Drag the custom control onto your xpage and populate the alertName property
<xc:ccBootAlert alertName="alertDemo2" id="ccBootAlertDemo2"></xc:ccBootAlert>
  • Call bootAlert from client-side js …
// Client side js 
var o = {}
o.title = "Client Side";
o.body = "This alert is being generated by client side javascript";
o.alertType = "danger";
o.alertIcon = "fa-calendar fa-lg"
bootAlert.show('alertDemo2',JSON.stringify(o))
  • or call bootAlert from server-side js by putting a value into a requestScope variable and making sure the bootAlert control is part of the partial refresh target:
// Server side js 
// This method assumes the alert is part of a partial refresh target
var o = {};
o.title = "Server Side";
o.body = "This alert is being generated from ssjs";
o.alertType = "info";
// The requestScope var name should match the alertName given to the bootAlert control
requestScope.put("alertDemo2",o);  
  • Finally, you can use view.postScript() to trigger a bootAlert:
// Server side js
// The alert custom control does NOT need to be part of a partial refresh target
// The parameters being passed to bootAlert need to be serialized
var o = {}
o.title = "Server Side > Client Side";
o.body = "This alert is being triggered by client side js called from server side js";
o.alertType = "warning";
o.autoClose = false;
view.postScript("bootAlert.show('alertDemo2'," + toJson(o) + ")");

I hope others find this control as useful as I have in my projects!


Copying Custom Controls

This tip is pretty simple, and it might be common knowledge to most people, but I stumbled onto it pretty much by accident.

Copying a custom control from one XPage to another is fairly common, but when you do so and go to build your new page, you get the message:

The prefix “xc” for element “xc:ccTest” is not bound.

error_message

Previously, I never really bothered to look into this message any further.  I took the easy way out and simply dragged a new copy of the custom control onto the XPage, copied any custom properties (if any), and went on my way.  However, this can get annoying REAL fast if you have a lot of custom controls that need to be copied.

Luckily, there is a ridiculously easy way to quickly get rid of the above message.

When you create a new Xpage, the standard markup looks like this:

<?xml version="1.0" encoding="UTF-8"?> 
<xp:view xmlns:xp="http://www.ibm.com/xsp/core"> </xp:view>

Look what happens as soon as you drag a custom control on to your XPage:

<?xml version="1.0" encoding="UTF-8"?>
<xp:view xmlns:xp="http://www.ibm.com/xsp/core"
	xmlns:xc="http://www.ibm.com/xsp/custom">
	<xc:ccTest></xc:ccTest>
</xp:view>

Adding the bolded line above to the xp:view tag of your page will allow you to copy custom controls to your XPage without frustration.  At the end of the day is it really a big time saver?  No.  But at least you have a better understanding of the error message.
