3.js 脚本
$(function () {
var defaultData;
$.ajax({
type: "post",
url: "项目请求路径方法.json",
dataType: "json",
success: function (result) {
defaultData=result;
var initSearchableTree = function() {
return $('#treeview-searchable').treeview({
data: defaultData,
nodeIcon: 'glyphicon glyphicon-globe',
emptyIcon: '', //没有子节点的节点图标
//collapsed: true,
});
};
var $searchableTree = initSearchableTree();
$('#treeview-searchable').treeview('collapseAll', {
silent : false//设置初始化节点关闭
});
var findSearchableNodes = function() {
return $searchableTree.treeview('search', [ $.trim($('#input-search').val()), { ignoreCase: false, exactMatch: false } ]);
};
var searchableNodes = findSearchableNodes();
// Select/unselect/toggle nodes
$('#input-search').on('keyup', function (e) {
var str = $('#input-search').val();
if($.trim(str).length>0){
searchableNodes = findSearchableNodes();
} else {
$('#treeview-searchable').treeview('collapseAll', {
silent : false //设置初始化节点关闭
});
}
//$('.select-node').prop('disabled', !(searchableNodes.length >= 1));
});
var search = function(e) {
var pattern = $.trim($('#input-search').val());
var options = {
ignoreCase: $('#chk-ignore-case').is(':checked'),
exactMatch: $('#chk-exact-match').is(':checked'),
revealResults: $('#chk-reveal-results').is(':checked')
};
var results = $searchableTree.treeview('search', [ pattern, options ]);
var output = '' + results.length + ' 匹配的搜索结果
';
$.each(results, function (index, result) {
output += '- ' + result.text + '
';
});
$('#search-output').html(output);
}
$('#btn-search').on('click', search);
$('#input-search').on('keyup', search);
$('#btn-clear-search').on('click', function (e) {
$searchableTree.treeview('clearSearch');
$('#input-search').val('');
$('#search-output').html('');
$('#treeview-searchable').treeview('collapseAll', {
silent : false//设置初始化节点关闭
});
});
},
error: function () {
alert("省市区地域信息加载失败！")
}
});
}); 三、后台主要代码 后台采用SpringMVC+Spring+Mybatis框架， 以下为Controller层代码
@ResponseBody
@RequestMapping(value = "/queryAreaInfo", method = { RequestMethod.POST }, produces = MediaType.APPLICATION_JSON_VALUE)
public List queryAreaInfo() {
List areaInfo=new ArrayList<>();
try {
//获取缓存中的省市区信息（本项目直接从缓存中获取，也可以单独写方法到Service、Dao层查询）
EcncSysConfig sysConfig = new EcncSysConfig();
areaInfo = sysConfig.INIT_SYS_ECNC_AREAVO;
} catch (Throwable e) {
e.printStackTrace();
}
//盛放省份
List result=new ArrayList<>();
for (AreaVO areaVO : areaInfo) {
Map map= new HashMap<>();
if("2".equals(areaVO.getGrade())){
map.put("text", areaVO.getName());
//盛放地市
List cList=new ArrayList<>();
for (AreaVO cVO : areaInfo) {
Map cMap=new HashMap<>();
if (cVO.getParentId() != null && cVO.getParentId().equals(areaVO.getId())) {
cMap.put("text", cVO.getName());
//盛放区县
List rList=new ArrayList<>();
for (AreaVO rVO : areaInfo) {
Map rMap=new HashMap<>();
if (cVO.getId().equals(rVO.getParentId())) {
rMap.put("text", rVO.getName());
rList.add(rMap);
}
}
cMap.put("nodes", rList);
cList.add(cMap);
}
}
map.put("nodes", cList);
result.add(map);
}
}
return result;
