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>
