AppSuite:Modifying forms by using extension points

Summary: This articles covers how to apply different changes to forms via modifying its extensionpoints and extensions.

The edit contact form of the contacts app is constructed by a set of extensionpoints. Each extensionpoint controls a single aspect - like the the input field for first name or the user picture - of the contact.

To apply modifications the id of the point and the extension is needed.

For a quick overview of the available extensionpoints and extensions you can use the browser console.

available extensionpoints

 
// get all available extensionpoints
require('io.ox/core/extensions').keys();

 
// you can filter down the list by using regular expression 
_(require('io.ox/core/extensions').keys()).filter(function (point) {
    if (/io.ox\/contacts\/edit/.test(point)) {
        return point;
    }
});

available extensions of a known point

 
// get all available extensions of a known extensionpoint
require('io.ox/core/extensions').point('io.ox/contacts/edit/personal').all();

some examples for modification

 
// replace a existing extension
require('io.ox/core/extensions').point('io.ox/contacts/edit/personal').replace({
    id: "first_name",
    draw: function () {
        this.append(
            $("<div>").addClass("title").text("Hello World!")
        );
    }
});

 
// modify the index to reorder a existing extension
require('io.ox/core/extensions').point('io.ox/contacts/edit/personal').replace({
    id: "first_name",
    index: 500
});

// introduce customize function 
require('io.ox/core/extensions').point("io.ox/contacts/edit/personal").extend({
    customize: function () {
        this.css("background", "#fc0");
    }
});
