Olivier Auverlot: "At my work (a universitary computer research laboratory), I'm alone to create all applications and databases. I don't know how I could do all the work without it. It's really a very productive software. I can focus on the database schemas and create quickly the user applications with a minimal amount of code to maintain".

OnEditFormEditorValueChanged

This event occurs on changing a value in the Edit form. Live example.

 

Signature:

function OnEditFormEditorValueChanged(sender, editors)

 

Parameters:

sender

A control whose value has been changed.

editors

An associative array of form controls. To access the value of the editor of the column_name column, use the editors['column_name'] syntax.

 

The examples below show how this method can be used in the OnInsertFormEditorValueChanged and OnEditFormEditorValueChanged event handlers.

 

Example 1:

The code below allows you to select a college only for players from U.S. (see this in action). See how it looks on the webpage at the screen below.

 

console.log(sender);

if (sender.getFieldName() == 'country_id')

{

  console.log(sender.getValue());

  editors['college_id'].enabled(sender.getValue() == 1);

  if (sender.getValue() != 1) { 

     editors['college_id'].setValue(null);

     $('#college_id_edit').next().show();

  }

  else

     $('#college_id_edit').next().hide();

 

 

Example 2:

Another example from the insert and edit forms of the Players page (see this in action). This piece of code allows you to select player number only if a player's team is already selected (in other words, players who do not belong to a team cannot have numbers).

 

if (sender.getFieldName() == 'current_team_id')

{

  if (sender.getValue() == '')

  {

    editors['current_number'].setValue('');

    editors['current_number'].enabled(false);  

    $('#current_number_edit').next().show();      

  }

  else

  {

    editors['current_number'].enabled(true);  

    $('#current_number_edit').next().hide();      

  }

}
