I have in a viewScope a hashmap stored but how can I read an entry from it e.g. from a computed text in SSJS ?
var pm = viewScope.get("person");
var entry = pm.entrySet();
return entry.getValue("email")
entrySet()
is a way for you to iterate your Map. For example:
Map<String, String> m = new HashMap<String, String>();
m.put("one", "1");
m.put("two", "2");
for (Map.Entry<String, String> entry : m.entrySet()) {
System.out.println(entry.getKey() + "=" + entry.getValue());
}
will print:
one=1
two=2
If you want to read a specific key from a map it's actually very simple:
<xp:text value="#{viewScope.person.email}" />
or if you need dynamic (where you would replace the literal value expressed with the quotes with another dynamic variable of your choosing):
<xp:text value="#{viewScope.person['email']}" />
