JSProperty (Function)
In french: JSPropriété
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 function is an advanced function: a good knowledge of Javascript is required.
Example
// If SAI_Saisie1 is an Control for entering the page
// the following statement displays the content of edit control
Info(JSProperty("_PAGE_." + SAI_Saisie1.Alias, "value"))
// Remark: We use the Property Alias
// to use the name of 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, uncheck the option "compress field names (Aliases)"..
// 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.

JSProperty handles the control aliases

  • in the code editor, press Shift + F11.
  • by programming, use Alias.
