param - java.util.Map
It's a map (Map<String, String>) of HTTP request parameter like the one returned by ServletRequest.getParameterMap()
If you visit a page with the URL like
http://localhost:8080/mypage.zul?p1=v1&p2=v2
Then you can retrieve parameters' value with the syntax below:
${param.p1}
${param.p2}
And the reulst will be:
v1
v2
To retrieve all possible parameter values, use paramValues instead.
${param.something}
${paramValues.something[0]}
Notice that, in zscript, there is no paramValues. Param is a map of possible values, Map<String, String[]>.
<zscript>
String[] values = param.get("something");
</zscript>
