指令：
app.directive('onBlankHide',function(){
return{
restrict:'A',
scope: {
pop: '='
},
link: function(scope,element,attr){
element.on('click',function(e){
//阻止底层冒泡
e.stopPropagation();
angular.element('#'+scope.pop).show();
});
angular.element('body').click(function(){
angular.element('#'+scope.pop).hide();
});
angular.element('#'+scope.pop).click(function(e){
//阻止底层冒泡
e.stopPropagation();
})
}
}
});
调用方法：
<a href="javascript:void(0)" on-blank-hide pop="'selLabel'" >弹框</a>pop是向指令传递的值，表示关联弹框的id名。
