BBjHtmlEdit::getPlainText

Description

In BBj 16.00 and higher, this method returns the plain text content of a BBjHtmlEdit control, without any HTML markup.

Syntax

Return Value	Method
string	getPlainText()

Parameters

None.

Return Value

Returns only the plain text content of a BBjHtmlEdit control.

Remarks

To return the complete HTML content, use getText.

Note: The BBjHtmlEdit control is always an HTML editor, intended to edit formatted text with HTML markup. This method is only a convenience, to return the plain text content with all HTML tags stripped out. Internally, this returns the JavaScript value document.body.innerText. If the content contains blank lines, this value is not guaranteed to return the same number of blank lines that the user sees in the editor. The BBjCEdit control may be a more appropriate choice if the application requires a very basic plain text editor.
