如何从GSP视图迭代Javascript中的Groovy集合

Question

I'm trying to iterate over the collection "times" in the code below. It's a list of map objects, each map has a time, name and modified field.

<r:script>
    <% def pos = 0%>
    for(var i = 0; i < ${jsonTimes.size()}; i++){
        console.log(${jsonTimes[pos].getAt("time")});
       <% pos++; %>
    }
</r:script>

either incrementing the "pos" variable as I am here, or jsonTimes[pos++] fails to increment the variable. Can I get some help with this please? Thanks!

Answer 1

You're mixing groovy and js. jsonTimes is a server side variable, so you should use groovy for iterations:

<g:each in="${jsontTimes}" var="jt">
  console.log(${jt.getAt("time").encodeAsJavaScript()});
</g:each>
