How to use the ${each} variable inside a zscript block
The ${each} is an Expression Language variable, and therefore, it cannot
be used directly inside a zscript block. But in some cases (especially
in event handlers) it's very useful to use ${each}. It's possible to define
a custom attribute, and place the variable in the custom-attributes map
for the component. With the ${each} is stored with key thename in the mentioned
map. In the zscript block, it's now possible to access this object with
componentScope.get("thename").
The data in the listbox component is shown with the help for the forEach attribute
in combination with the ${each} EL (Expression Language) variable.
The full implementation of the redesigned page is given below. Here, we want
to mix elements from XHTML with elements from ZUL. For that we need a clear
separation of the two worlds. In an XML file, there is an element that helps us to do
this separation, the namespace. If we use a namespace we have to add a prefix to
each tag from that namespace (e.g. ). For further information about
namespaces visit http://www.w3.org/TR/REC-xml-names/.
