Applies to version 8.3.1.x; Author: Grzegorz Straś

Update BPS 2017.1 – Form rules have replaced JavaScript fields which influence the form. JavaScript can still be used inside form rules. The order in which form rules are executed can be found here:

In WEBCON BPS, JavaScript executed on page load and on value change will be performed in a predefined order. These scripts can be included in workflow, step and form field configurations – and the order in which they are executed depends solely on where they are defined in Designer Studio.

Listed below are the orders in which scripts are executed:

a) Whenever the page is loaded

b) When the value of a form field is altered (only with postback on value change active).

 

JavaScript sequence whenever the page is loaded:

Order	Configuration	Tab	JS field name	Visual	Note
1	Form field configuration	Style and behavior	Script to be registered		According to form field ID
2	Workflow configuration	Behavior	JavaScript to be registered on the webpage
3	Step edit	General	JavaScript executed on page load
4	Workflow configuration	Behavior	JavaScript to be executed on page load
5	Workflow configuration	Behavior	JavaScript to be executed on page load and on postback
6	Step edit	General	JavaScript executed on page load and on postback

 

JavaScript sequence on value change:

If the Change of value causes postback checkbox is set in the form field configuration, the order of running JavaScript (whenever that form field’s value is modified) is as follows:

Order	Configuration	Tab	JS field name	Visual	Note
1	Form field configuration	Style and behavior	Script to be executed on value change
2	Form field configuration	Style and behavior	Script to be registered		According to form field ID
3	Workflow configuration	Behavior	JavaScript to be registered on the webpage
4	Workflow configuration	Behavior	JavaScript to be executed on page load and on postback
5	Step edit	General	JavaScript executed on page load and on postback
