freemarker list (長度,遍歷,下標(biāo),嵌套,排序)
- freemarker獲取list的size ：
Java
ArrayList<String> list = new ArrayList<String>();
Freemaker
${list?size} - list的遍歷：
<#list animals as being>
<tr>
<td>{being.price}<td>
</tr>
</#list> - 遍歷MAP
<#list map?keys as k>
<option value="{map[k]}</option>
</#list>
4.list遍歷中的下標(biāo)序號：
_index是list的一個屬性
<#list list as a>
{list[i]}
嵌套時前面要有括號，如下，將字符串變成list，然后取第i個元素的值
${(str?split(","))[i]} - list的嵌套：
<#list jsskList as jsskVO>
<#list kcList as kcVO>
<#if kcVO.kch=jsskVO.kch> （kcVO里有編號和名稱，而jsskVO里只有編號）
${kcVO.kcm}
</#if>
</#list>
</#list> - list排序：
升序 .sort_by()
<#list list?sort_by("字段") as x>
</#list>
降序 .sort_by()?reverse
<#list list?sort_by("字段")?reverse as x>
</#list>
8.item_has_next,size使用：
<#list userList as user>
<#if !user_has_next>
共有{user.userName}
</#if>
</#list>
兩個實例:
后臺:
@Controller
@RequestMapping("/model/template")
public class ModelController extends BaseController {
@RequestMapping(value = "/querySearch")
public String querySearchController(@RequestParam(value = "content") String content,Model model){
JSONObject jsonObject=new JSONObject();
jsonObject.put("ceshi","測試");
jsonObject.put("xiaoxi","成功");
model.addAttribute("jsonObject",jsonObject);
return "admin/model/returnSearch";
}
}
========
@Controller
@RequestMapping("/citypage")
public class CityController {
@RequestMapping(value = "/api/city", method = RequestMethod.GET)
public String findAllCity(Model model) {
List<City> cityList = cityService.findAllCity();
model.addAttribute("cityList",cityList);
return "admin/model/cityList";
}
}
