Managing client hyperlinks
For client hyperlinks, an HTML anchor <A> element
directly links one page to another. On the linking page, you specify
the parameters (including the type of binding and the value for
the parameter) you want to pass to parameters on the target page.
The following drawing illustrates how parameters are made
available to a target page from a hyperlink on a linking page in
a target. Parameters are passed the same way for JSP targets, except
that the target and linking pages would typically have .jsp extensions
instead of the .htm extensions displayed in
the drawing:
The server sets the parameters sent to the target page. Only
initial values are passed to the target parameters; client-entered
values are not processed.
To pass parameters with a client hyperlink:
-
Drag an HTML A element
from the Language tab of the System Tree to a 4GL Web page in the
HTML editor (Page or Source view)
or
Click
the hyperlink tool button in the painter bar for the HTML editor
with a 4GL Web page open in Page or Source view.The Hyperlink Properties dialog box displays.
-
On the Hyperlink page, specify link information,
including a target page destination.Make sure the Server-Side Scriptable check box is selected.
-
On the Parameters page, specify page parameters
for the target page, the type of binding for each parameter, and
the value from the current page that you want to bind to each parameter.
If not 4GL If the linking page is not 4GL, the Parameters tab is grayed
out.If the linking page is 4GL and the target page exists and
has page parameters defined for it, these parameters display automatically
under the Parameter Name column. They are available for binding
to constants, expressions, page parameters, and page variables from
the current page.You can add new parameters to the list and define them later
in the target page. Parameters and variables on the current page
automatically display under the Bind Value column when you select
a bind type of Page Parameter or Page Variable, respectively.
-
Click OK after you finish setting the hyperlink
properties.
