keydown可用于添加快捷键。

keyup可以用于实时查询、校验数据。

上一文章修改的input

<input type="text"id=inputable'+""+tableuniqueflag+'name=""value="" ng-keydown="keyCheck();" ng-keyup="showtabledivcr();" ng-focus="focusshowtabledivcr($event);"ng-blur="closewin($event);" ></input>

$scope.showtablediv= function (){...略//方向键和回车键不触发，防止选中之后重新触发创建表格函数if(keycode=="37"||keycode=="38"||keycode=="39"||keycode=="40"||keycode=="13"){return;}...略$scope.createMyTable(rows,cells);...略}
