While creating DOJO Components when should we prefer declarative approach and programatic approach?
Depends entirely on your needs and preferences. If you have designers rather than programmers needing to add Dojo widgets, it may be preferable for them to use the declarative markup. However, if you insist that the HTML markup pass w3c validation, you’ll want to use the programmatic approach instead.
I prefer the programmatic approach because it allows me to wrap an entire form as a javascript object and create methods to instantiate and validate its widgets. Addendum after comment: I will usually create a javascript object with its form inputs and dojo/dijit widgets as its properties so I can refer to them as
this.startDateTextBox, this.titleInlineEditoretc. I handle the instantiation of the dojo widgets in the javascript object constructor function.If you use multiple similar widgets, there can be a savings in typing errors if you declare objects that hold their initialization settings and load them programmatically instead of declaring all the shared properties in the markup for each one declaratively. Another reason I prefer programmatic instantiation is that I can change the instantiation parameters based on different conditions before actually starting up a widget more easily than if I had to do it server-side to change the markup.
