Allows you to handle specific features on the objects found in the current page. Allows you to:
  • read the JavaScript property of an object found in the current page
  • assign a value to the JavaScript property of an object found in the current page.
This is an advanced function, requiring a good knowledge of Javascript.
Ejemplo
// If EDT_Edit1 is an Edit control of the page
// the following statement displays the content of edit control
Info(JSProperty("_PAGE_." + EDT_Edit1.Alias, "value"))
// Note: We use the Alias property 
// to handle the name of the generated control in the HTML page
// Fill the numeric edit controls named EDIT1, EDIT2 and EDIT3 
// with the "test" value
i is int
FOR i = 1 TO 3
	JSProperty("_PAGE_.EDIT" + i, "value") = "test"
END
// CAUTION:
// For this example, clear the "Compress the control names (Alias)" option.
// This option is found: 
// - in the advanced options of the page 
// ("Advanced" tab of the page description, 
// "Custom optimization of HTML code" option)
// - in the advanced options of the project ("Advanced" tab, "Advanced" button). 
// This allows you to keep the names of the generated controls 
// in the HTML pages as they have been defined in the editor.
// You will notice that the names of controls are always generated in uppercase.
