Timed advance

select_one with "quick" appearance

numeric	select_one	select_multiple

Description

Most of the functionality of this field plug-in have been taken over by the timed-choice field plug-in. If you would like to time a select_one or select_multiple field, use the the timed-choice field plug-in instead. If you are timing a text, integer, or decimal type field, continue to use this field plug-in.

Requires at least Android 7 or iOS 13 to work on SurveyCTO Collect.

See supported field types below. This field plug-in does not yet have the extended HTML suppport present in the baseline-select_one field plug-in.

Features

• Time a text, integer, decimal, select_one, or select_multiple type field
• Auto-advance after time runs out
• Auto-advance if enumerator/respondent attempts to return to the field (can be changed with parameter 4, see Parameters below)

Data format

If an answer is entered/selected before time runs out, then the answer entered or the value of the choice selected will be set as the field value. However, if nothing is entered or selected, then the field will have a value of -99. This can be changed with the pass parameter.

How to use

Getting started

To use this field plug-in as-is, just download the timedadvance.fieldplugin.zip file from this repo, and attach it to your form.

To create your own field plug-in using this as a template, follow these steps:

1. Fork this repo

2. Make changes to the files in the source directory.

   • Note: be sure to update the manifest.json file as well.

3. Zip the updated contents of the source directory.

4. Rename the .zip file to yourpluginname.fieldplugin.zip (replace yourpluginname with the name you want to use for your field plug-in).

5. You may then attach your new .fieldplugin.zip file to your form as normal.

Important: When using on a select_one or select_multiple field, you need to include a choice with the value of -99. This choice will be hidden by the field plug-in, but it will be selected if the time runs out without a choice selected.

Parameters

The order of the parameters matters. For example, you cannot specify the continue parameter without first specifying the first 3 parameters.

There are four parameters, but all of them are optional.

Number	Name	Description	Default
1.	duration	Time in seconds before the field auto-advances. No matter what unit is used for parameter 2, you should always enter the duration in seconds.	10
2.	unit	Unit to be displayed for the time remaining. The time will be shown as the correct converted version. For example, if the start time is 15 seconds, and the unit is 'ms' for milliseconds, the time will be displayed at the start as 15000.	's'
3.	pass	The value the field will be given if time runs out before an answer is given.	-99
4.	continue	Whether a respondent can return to a field and continue with the time they have left. For example, if there was 5 seconds remaining when they swiped forward, they can return to that field and work with that remaining 5 seconds. To allow this, give this parameter a value of 1.	0

For parameter 2, you can use the following display units:

Abbr.	Full name	Unit in 1 second
s	seconds	1
ds	deciseconds	10
cs	centiseconds	100
ms	milliseconds	1000

For example, if you would like the field to move forward after 20 seconds, you can use this appearance:

custom-timedadvance(duration=20)

If you would like the time to be displayed in milliseconds, you can use this appearance:

custom-timedadvance(duration=20, unit='ms')

If the field is of type select_one, you would like it to have the quick appearance, and the field should last 15 seconds, you can use this appearance:

quick custom-timedadvance(duration=15)

If you would like the respondent to have 15 seconds to complete the field, but they can return to it later to change their answer with their remaining time, you can use this appearance:

quick custom-timedadvance(duration=15, unit='s', pass=-99, continue=1)
