} - 服务准备
{

context.Response.ContentType = context.Response.Write(result);
}
{

}
} - 界面控件处理，并引入AngularJS

;
] = ] = ] = ] = $scope.tempCate.filter(function(value, index, array) {

];
; i > ; i--) {
];
< <option value= </ < <option value= </ <asp:HiddenField runat= </div>
<asp:Button ID= </form>
</body>
</html> - 后台代码
{
LoadCategoryId = ;
}
}
{
Button1.Text = hfCategory.Value;
}
} - 说明
- 需要引入angular.js和ui-bootstrap.js
- AngularJS的$scope.$watch很有用
- 借助隐藏域实现前台台数据传递
