使用时区创建Customer时,timeZone具有该值。当我显示timeZone时,我想显示所选的选项。
例如,我想显示 SST,萨摩亚标准时间-11:0.0(选定选项)而不是太平洋/中途(价值)。
我需要在显示页面中更改此功能吗?
类客户{
static constraints = {
}
String name
String timeZone
}
在create.gsp中:
<div class="fieldcontain ${hasErrors(bean: customerInstance, field: 'timeZone', 'error')} ">
<label for="timeZone">
<g:message code="customer.timeZone.label" default="timeZone" />
</label>
<g:if test="${customerInstance?.timeZone}">
<g:timeZoneSelect name="timeZone" value="${TimeZone.getTimeZone(customerInstance?.timeZone)}" />
</g:if>
<g:else>
<g:timeZoneSelect name="timeZone" value="${customerInstance?.timeZone}" />
</g:else>
</div>
show.gsp中的:
<span class="property-value" aria-labelledby="timeZone-label"><g:fieldValue bean="${customerInstance}" field="timeZone"/></span>
答案 0 :(得分:0)
我找到了解决方案
def show(Long id) {
def customerInstance = Customer.get(id)
if (!customerInstance) {
flash.message = message(code: 'default.not.found.message', args: [message(code: 'customer.label', default: 'Customer'), id])
redirect(action: "list")
return
}
def date = new Date()
TimeZone tz = TimeZone.getTimeZone(customerInstance.timeZone);
def shortName = tz.getDisplayName(tz.inDaylightTime(date), TimeZone.SHORT);
def longName = tz.getDisplayName(tz.inDaylightTime(date), TimeZone.LONG);
def offset = tz.rawOffset;
def hour = offset / (60 * 60 * 1000);
def min = Math.abs(offset / (60 * 1000)) % 60;
def timeZone= shortName+", "+longName+" "+hour+": "+min
[customerInstance: customerInstance,timeZone:timeZone]
}
在Show.gsp中:
<span class="property-value" aria-labelledby="timeZone-label">${timeZone}</span>
