Hiermenus Go Forth, V:
Version 4 - The Page-Specific Parameters (cont'd)

HM_PG_ImageSrc

Description

The filename for the "more" image displayed in items that have associated child menus. All menus in the page, in all cascades (top-level and children) are affected.

HM_PG_ImageSrc overrides site-wide global settings declared in the external script.

HM_PG_ImageSrc will not cause an image to be displayed in any menu trees that have the top_more_images_visible or tree_more_images_visible parameter elements in top-level menu arrays set to false.

Value

Valid GIF or JPG filename.
May be specified as:

• string
• string JS expression to be evaluated

Example Values

string: "http://www.mydomain.com/myimagedirectory/tri.gif"

All items with associated child menus on the page will display the image stored at the above URL.

JS expression: "getImageSrc()"

A custom function that you have created will be called. The return value of this function will be the HM_PG_ImageSrc parameter, and all menus in the page will comply.

JS expression: "(IE4) ? 'http://www.mydomain.com/myimagedirectory/IEimage.gif' : 'http://www.mydomain.com/myimagedirectory/NSimage.gif'"

The complete JS code is included in the parameter declaration. In the above example, HM_PG_ImageSrc will be http://www.mydomain.com/myimagedirectory/IEimage.gif if Explorer is being used, and http://www.mydomain.com/myimagedirectory/NSimage.gif if it is not.

Default

If this parameter is omitted, the relevant Global Parameter value set in the external script is used.

Differences from Version 3 equivalent

The imgSrc parameter in Version 3:

• was mandatory.
• did not accept JS expression values.

Next, HM_PG_ImageSize.
