AngularJs 鍵盤事件和鼠標事件

ngKeydown/ngKeypress/ngKeyup

該指令在按鍵按下/按鍵按下/按鍵松開時執行指定表達式。

ngKeydown和ngKeypress略有不同，目前的測試是ngKeypress針對系統按鍵是無效的，而ngKeydown可以。

ngKeyup指令在按鍵松開的時候執行。

使用代碼：

  <input ng-keydown="count = count + 1" ng-init="count=0">{{count}}
  <input ng-keypress="count = count + 1" ng-init="count=0">{{count}}
  <input ng-keyup="count = count + 1" ng-init="count=0">{{count}}

ngMousedown/ngMouseenter/ngMouseleave/ngMousemove/ngMouseover/ngMouseup

該指令在鼠標按下/鼠標進入/鼠標離開/鼠標移動/鼠標在上面/鼠標松開時執行指定表達式。

使用代碼：

  <button ng-mousedown="count = count + 1" ng-init="count=0">on mouse down</button>{{count}}
  <button ng-mouseenter="count = count + 1" ng-init="count=0">when mouse enter</button>{{count}}
  <button ng-mouseleave="count = count + 1" ng-init="count=0">when mouse leave</button>{{count}}
  <button ng-mousemove="count = count + 1" ng-init="count=0">when mouse move</button>{{count}}
  <button ng-mouseover="count = count + 1" ng-init="count=0">when mouse is over</button>{{count}}
  <button ng-mouseup="count = count + 1" ng-init="count=0">on mouse up</button>{{count}}
