(Quick Reference)
each
Purpose
Uses a "for(var in collection)" loop to iterate over each element of the specified object.
Examples
<g:each in="${books}">
<p>Title: ${it.title}</p>
<p>Author: ${it.author}</p>
</g:each>With a named item:
<g:each var="book" in="${books}">
<p>Title: ${book.title}</p>
<p>Author: ${book.author}</p>
</g:each>With a range literal - note how the literal must be enclosed in parentheses:
<ul>
<g:each var="i" in="${ (0..<100) }">
<li>Item ${i}</li>
</g:each>
</ul>Another example, where a named item is necessary (otherwise the access to the title property will fail):
<g:each in="${itemList}" var="item">
<g:link action="show" id="${item.id}">${item.title}</g:link>
</g:each>Using the status parameter to alternate the coloring of a table's rows:
<tbody>
<g:each status="i" in="${itemList}" var="item">
<tr class="${ (i % 2) == 0 ? 'a' : 'b'}">
<td>${item.id?.encodeAsHTML()}</td>
<td>${item.parentId?.encodeAsHTML()}</td>
<td>${item.type?.encodeAsHTML()}</td>
<td>${item.status?.encodeAsHTML()}</td>
</tr>
</g:each>
</tbody>Description
Attributes
