E4HtmlElement_Intf

public class A_ReturnValue
extends E4HtmlContentElement
implements E4HtmlElement_Intf

This anchor tag stands only at the end of selection mechanisms. Pickup means, that there is a form containing an input field (E4InputField_Intf), where a method (E4MethodPickup) was defined for pickup. This means, that a symbol will be displayed and the user has the chance to click on that symbol, a window openes and values are displayed for selection. The user can click on one of those values, to overtake into the input field using the A_ReturnValue class. When the pickup is defined, it will be done using the A_FORM class instead of the normal <A;gt;-Tag (but very similar to) which extendes to optionally include other input fields (as the "calling" field) of the form as well.

Method Detail

createReturnScript

public static E4JavaScript createReturnScript(E4CgiParams params)

Create a return script. This overtakes the value specified as E4JavaScript parameter to the caller's window and sets the field value in the form. Closes the window, does not set the focus.

Parameters:

params - the params supported by a E4MethodPickup method

Returns:

a E4JavaScript that can be used but which is not bound to any element

createReturnScript

public static E4JavaScript createReturnScript(E4CgiParams params,
                                              boolean can_setfocus)

Create a return script. This overtakes the value specified as E4JavaScript parameter to the caller's window and sets the field value in the form. Closes the window.

Parameters:

params - the params supported by a E4MethodPickup method

can_setfocus - if true sets the focus on the field in the calling window

Returns:

a E4JavaScript that can be used but which is not bound to any element

createReturnScript

public static E4JavaScript createReturnScript(E4CgiParams params,
                                              boolean can_setfocus,
                                              boolean close_window)

Create a return script. This overtakes the value specified as E4JavaScript parameter to the caller's window and sets the field value in the form.

Parameters:

params - the params supported by a E4MethodPickup method

can_setfocus - if true sets the focus on the field in the calling window

close_window - if true closes the current window (which is likley the pickup window)

Returns:

a E4JavaScript that can be used but which is not bound to any element

toHtml

public void toHtml(E4StringBufferHtml buf,
                   E4ServletImplementation_Intf servlet)
            throws java.lang.Exception

Description copied from interface: E4HtmlElement_Intf

Create the HTML output for this element. Also run throught all child elements, and call their E4HtmlElement_Intf.toHtml(e4s.util.E4StringBufferHtml, e4s.servlet.E4ServletImplementation_Intf) function to generate output of those objects which becomes appended. Normally, there is no need to call this function anyway, and this also might result in side effects of too-early relasing of objects in some cases. This function is called by E4ServletImplementation_Intf.write(e4s.html.E4HtmlElement) on the top level HTML element (common this is a HTML or BODY element) and branches down to all child elements.

Specified by:

toHtml in interface E4HtmlElement_Intf

Overrides:

toHtml in class E4HtmlElementGeneral

servlet - the servlet environment currently running in

Throws:

java.lang.Exception

toString

public java.lang.String toString()

Intended for debug only.

Overrides:

toString in class E4Object

makeUniqueName

protected static final java.lang.String makeUniqueName(java.lang.String s)

_getSVNVersionString

public static java.lang.String _getSVNVersionString()

Get version info string from subversion.

Returns:

the version info string.
