假设当前在gsp中:
<g:each in="${prospectProjectStatuses}" var="statusObj">
<%-- Number active and inactive projects --%>
<g:if test="${statusObj?.project?.active == true}">
<g:set var="numActiveProjects" value="${numActiveProjects + 1}"/>
</g:if>
<g:else>
<g:set var="numInactiveProjects" value="${numInactiveProjects + 1}"/>
</g:else>
<%-- Number of hidden rows to show --%>
<g:if test="${!statusObj?.project?.id.intValue() && !canEdit && statusObj?.status?.id}">
<g:set var="numProjectsToShow" value="${numProjectsToShow + 1}"/>
</g:if>
<g:if test="${statusObj?.project?.active && statusObj?.status?.id}">
<g:set var="numStatusSet" value="${numStatusSet + 1}"/>
</g:if>
</g:each>
Controller 方法中的每个循环等效于什么?
最佳答案
在您的集合上调用each()。因此,示例gsp的等效内容如下所示:
prospectProjectStatuses.each { statusObj ->
if (statusObj?.project?.active) {
numActiveProjects += 1
} else {
numInactiveProjects += 1
}
if (statusObj?.project?.id.intValue() && !canEdit && statusObj?.status?.id) {
numProjectsToShow += 1
}
if {statusObj?.project?.active && statusObj?.status?.id) {
numStatusSet += 1
}
}
