因專案對區域的樣式有要求，而select標籤的option不能自定義，故通過div實現select標籤的選擇效果。

說明如下：

1.實現點選文字框和⌵區域框出現，點選其他地方區域框關閉，通過在該頁面的最大級div(非body)上增加點選事件實現：ng-click="areaHide($event)";
2.為實現整個框都可以點選，增加$event.stopPropagation()，阻止冒泡；
3.專案中區域共3種關係，本案例選擇網公司賬號演示；
4.SearchArea控制區域框的出現，showCity控制省、市出現，allQuery控制全部，因省級全部體現在資料庫，故不用單獨控制。

html：

<div class="service-list" ng-click="areaHide($event);">
    <div class="commonBg common-tab-height marginB20">
        <div class="col-xs-8">
            區域：
            <div class="pend-width pull-relative commonAreaDiv" ng-click="choose();$event.stopPropagation();">
                <span ng-show="pendReqInfo.cityName==null || (pendReqInfo.cityName==null && pendReqInfo.province=='nw')">{{pendReqInfo.provinceName}}</span>
                <span ng-show="pendReqInfo.cityName!=null && pendReqInfo.province!='nw'">{{pendReqInfo.cityName}}</span>

                <!--區域彈窗-->
                <div class="commonSearchArea" ng-if="SearchArea" ng-class="{'searchArea-width':!showCity,'searchArea-width2':showCity}">
                    <div class="no-padding first-area" ng-class="{'col-xs-6':showCity,'col-xs-12':!showCity}">
                        <div class="pend-menu">

 css

/*區域及類似選擇框*/
.commonAreaDiv{
    display: inline-block;
    color: #A1A1A1;
    padding: 6px 12px;
    margin-bottom: 0;
    white-space: nowrap;
    vertical-align: middle;
    cursor: pointer;
    border-radius: 4px;
    text-align: left;
    border: 1px solid #D7D7D7;
    height: 32px;
}
.commonAreaDiv:before{
    content: '⌵';
    position: absolute;
    top: 0;
    right: 10px;
    font-size: 18px;
    color: #D7D7D7;
    font-weight:bold;
}
.commonSearchArea{
    position: absolute;
    top: 31px;

    z-index: 1000;

資料結構示意如下：

$scope.provinces = [
    {
        areaName: null,
        cityCode: null,
        code: "gd",
        id: "gd030000000000002",
        level: "2",
        name: "廣東",
        parentId: "-1",
        powerCode: null,
        provinceCode: null,
    },
];
$scope.cities = [
    {
        areaName: null,
        cityCode: "0302",
        code: "0302",
        id: "gd030200000000083",
        level: "3",
        name: "韶關",
        parentId: "gd030000000000002",
        powerCode: null,
        provinceCode: "gd",
    },
];

區域聯動效果如下：
