Modal dialogs are notifications that pop up in the user’s face and must be acted on if the user want to continue. It’s quite an intrusion—people tend to dislike popups, so they should only be used if the interaction is essential.

It’s quite exciting: our functionality is captured in a chainable, reusable plugin that we’ve nestled in between the hide and slideDown actions. you can see it’s worth turning any functionality you intend on reusing into a plugin!. We can add user-specified options to our plugins, which can then be used to modify the plugin’s behavior when...

chapter_09/11_custom_events/script.js (excerpt). We have bound our custom do-toggle event to the disclaimer element. When the do-toggle event fires, the function will run and the disclaimer will hide or show itself. When the button is clicked, the disclaimer is toggled. It might seem like the long way round compared to just hiding and showing with the toggle button, but now we’ve...

Now at a future point when the user clicks on the map and the locator’s click handler fires, we’ll have access to the locationData object:. Although in many cases we’d probably want to store the element reference in the object itself, when the objects are coming from third-party code, you have to be very careful with ađing or removing properties....

But over time, in the way a constant drip can erode even the hardest granite, it came to permeate my thinking. When I began the research study on developing an appropriate dual-mode design model documented in the present log, I thought I had the world by the tail. I had over 12 years’ experience in the field of instructional design...

As the design work took place over...

Consequently, aware of the risk that he could decide, at any minute, to completely stop the design of his course, I decided to forego development temporarily. Even if I try to be linear and systematic in my application of the ISD model, I feel pressure to answer very specific needs (help in designing an exam, enriching a case study, designing...

Having established a functional modus operandi, the professor once again said he was willing to complete this work between our sessions.. This kind of study of the correlation between exam items and course objectives constitutes a good example of reverse engineering in design, a useful technique in cases where it is difficult to identify the objectives a faculty member actually...
