map = new BMap.Map("l-map", {minZoom:15})//初始化地图，规定最小缩放
map.centerAndZoom(new BMap.Point(113.402364,23.056676), 16)//显示中心
map.enableScrollWheelZoom()//启用滚轮缩放
要实现的功能是，在ng-app中定义的全局变量，在不同的ng-controller里都可以使用。1，通过var 直接定义global variable，这根纯js是一样的。
2，用angularjs value来设置全局变量 。
3，用angularjs constant来设置全局变量 。
首先是html页面的编写：
<!doctype html><html ng-app="myModule">
<head>
<meta charset="utf-8">
<title>学生信息管理</title>
//需要用到的一些库，要加载的
<script src="bower_components/angular/angular.js"></script>
<script src="bower_components/ng-table/dist/ng-table.js"></script>
<script src="bower_components/ng-table-export/ng-table-export.js"></script>
<link rel="stylesheet" type="text/css" />
<link rel="stylesheet" type="text/css" />
<link rel="stylesheet" type="text/css" >
<script src="module/scripts/controllers/Form.js"></script>
</head>
<body>
<div ui-view></div>
<div ng-controller="FormController">
<h3>学生信息列表</h3>
<br>
<div>
搜索：<input type="text" ng-model="titleFilter" placeholder="输入关键字"> //加上<tr ng-repeat="student in students|filter:titleFilter">实现了表格内容的检索。
</div>
<br>
<table ng-table="tableParams" >
<tr ng-repeat="student in students|filter:titleFilter"> //遍历每一个对象
<td title="'Name'">
<span ng-if="!student.$edit">{{student.Name}}</span>
<div ng-if="student.$edit"><input type="text" ng-model="student.Name"></div>
</td>
<td title="'Id'">
<span ng-if="!student.$edit">{{student.Id}}</span>
<div ng-if="student.$edit"><input type="text" ng-model="student.Id"></div>
</td>
<td title="'Grade'">
<span ng-if="!student.$edit">{{student.Grade}}</span>
<div ng-if="student.$edit"><input type="text" ng-model="student.Grade"></div>
</td>
<td title="'Actions'" width="200">
<a ng-if="!student.$edit" ng-click="student.$edit=true">Edit</a>
<a ng-if="student.$edit" ng-click="student.$edit=false">Save</a>
<a ng-click="deleteStudent(obj)" ng-if="student.$edit" >Delete</a>
<!-- <a ng-click="addStudent()" ng-if="student.$edit" >Add</a> -->
</td>
</tr>
</table>
<div>
<input type="text" ng-model="newName" placeholder="input Name" required/>
<input type="text" ng-model="newId" placeholder="input Id" required/>
<input type="text" ng-model="newGrade" placeholder="input Grade" required/>
<input type="button" ng-click="addStudent()" value="Add" />
</div>
</div>
</body>
</html> 接下来是js代码部分 var myModule=angular.module('myModule',['ngTable']).
controller('FormController',function($scope,ngTableParams,$sce){
$scope.students=[
{Name:'小李',Id:'201401201',Grade:'计算机技术'},
{Name:'李磊',Id:'201401202',Grade:'计算机技术'},
{Name:'夏津',Id:'201401203',Grade:'计算机技术'},
{Name:'杭州',Id:'201401204',Grade:'计算机技术'}
]
$scope.addStudent=function(){ //添加学生函数
$scope.students.push({Name:$scope.newName,Id:$scope.newId,Grade:$scope.newGrade})
$scope.newName=''
$scope.newId=''
$scope.newGrade=''
}
$scope.deleteStudent=function(student){ //删除一行的内容
$scope.students.splice($scope.students.indexOf(student),1)
}
})
