比较两个对象discs、outlets中的元素是否相等。相同则相应的checkbox为checked

<div id="div1" name="div1" class="area" style="position:relative;">

<c:if test="${!empty outlets}">

<dl>

<c:forEach items="${outlets}" var="outlet">

<c:set var="has" value="0" ></c:set>

<dd>

<c:if test="${!empty discs}">

<c:forEach items="${discs}" var="discs">

<c:if test="${discs.outlet==outlet.outlet}">

<c:set var="has" value="1"></c:set>

</c:if>

</c:forEach>

</c:if>

<input id="outlet" type="checkbox" value="${outlet.outlet }" id="${outlet.outlet }" name="outlet" <c:if test="${has==1}">checked="checked"</c:if> />

<label for="${outlet.outlet }">${outlet.outlet }-${outlet.desc1 }</label>

</dd>

</c:forEach>

</dl>

</c:if>

</div>

 

Controller传输discs，outlets

List<DiscS> discs=discSService.getDiscSByCode(code);

/* System.out.println(discs.get(0).getOutlet()+"@@");

System.out.println(discs.get(1).getOutlet()+"！！");

System.out.println(discs.get(2).getOutlet()+"##");*/

model.addAttribute("discs",discs);

List<Outlet> outlets = outletService.getOutlets();

/*System.out.println(outlets.get(0).getOutlet());

System.out.println(outlets.get(1).getOutlet());

System.out.println(outlets.get(2).getOutlet());*/

model.addAttribute("outlets", outlets);
