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

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"'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
  • 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("'alertDemo2'," + toJson(o) + ")");

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

XPages tip: Using jQuery class selectors with hidden inputs

If you cut your XPages teeth by using the out-of-the-box-included dojo libraries, then you are probably intimately familiar with dojo.byId(“#{id:myElementID}”) to locate elements on your XPage based on the id attribute.

After starting to weave jQuery into your projects, you probably realized pretty quickly that the jQuery id selector syntax of $(“#myElementID”) does not work well with XPage component ids. But of course there is a solution for that – Marky Roden’s XSnippet which wraps the jQuery ID selector function in a XPage version.

Due to the above issues with getting elements by ID in jQuery, you probably started using class selectors such as $(“.myClassName”). This is all fine and good – until you go to add a class to the properties panel of a hidden input control:

As you can see from the screenshot above, there is no place to enter a class name in the properties for a hidden input control. Seems kind of silly, doesn’t it? It’s a field. Fields have classes. I should be able to add a class to a hidden field. Apparently not.

Luckily, there is an incredibly simple way to do this using the attrs properties in the basics section of the properties panel:

  • Add a new attribute by clicking the plus sign
  • In the name field, enter “class” (do not add the quotes)
  • In the value field, enter the name of your class, for example, “myClassName” (again, no quotes)

Now, you should be able to access your hidden input using a jQuery selector.
