angularjs 弹出框 $modal
$modal只有一个方法:open,该方法的属性有:
-
templateUrl
:模态窗口的地址 -
template:用于显示html标签
-
scope
:一个作用域为模态的内容使用(事实上,$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
