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 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 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 "Compress the name of controls (..Alias)".
// 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.
