AngularJS $modal弹出框实例代码

下面给大家说下$modal拥有一个方法:open,该方法的属性介绍:

templateUrl:模态窗口的地址

template:用于显示html标签

scope:一个作用域为模态的内容使用(事实上,$modal会创建一个当前作用域的子作用域)默认为$rootScope

controller:为$modal指定的控制器,初始化$scope,该控制器可用$modalInstance注入

resolve:定义一个成员并将他传递给$modal指定的控制器,相当于routes的一个reslove属性,如果需要传递一个objec对象,需要使用angular.copy()

backdrop:控制背景,允许的值:true(默认),false(无背景),“static” - 背景是存在的,但点击模态窗口之外时,模态窗口不关闭

keyboard:当按下Esc时,模态对话框是否关闭,默认为ture

windowClass:指定一个class并被添加到模态窗口中

open方法返回一个实例,该实例具有如下属性:

close(result):关闭模态窗口并传递一个结果

dismiss(reason):撤销模态方法并传递一个原因

result:一个契约,当模态窗口被关闭或撤销时传递

opened:一个契约,当模态窗口打开并且加载完内容时传递的变量

另外,$modalInstance扩展了两个方法$close(result)、$dismiss(reason),这些方法很容易关闭窗口并且不需要额外的控制器
