Javascript API: Control object

About Control object

The Control object allows you to work with the edit controls. Control object is available in the JavaScript OnLoad event of Add/Edit pages.

Before you start working with the edit controls, you need to get those controls.

getControl()

Use the getControl() method to get the controls by the field name and page ID:

Syntax

var ctrl = Runner.getControl(pageid, fieldname);

Example

var ctrl = Runner.getControl(pageid, 'Make');

controls.ControlManager.getAt(tableName)

To get all the controls of the table, you need to pass only the table name as the argument:

Syntax

var ctrlArr = Runner.controls.ControlManager.getAt(tableName);

Example

// Get all the controls for the 'Cars' table
var recCtrlsArr = Runner.controls.ControlManager.getAt('Cars');
// loop through all controls on the page making them all required
for(var i=0;i<recCtrlsArr.length;i++)
{
var ctrl = recCtrlsArr[i];
ctrl.addValidation("IsRequired");
}
