AngularJS仿苹果滑屏删除控件

<div class="row-class" ng-repeat="item in list">
这是整行显示的内容
</div>

<div class="row-class" ng-repeat="item in list" slide-delete text="删除" ondelete="ondelete(item)">
这是整行显示的内容
</div>

myapp.directive('slideDelete', function() {
return {
restrict: 'AE',
scope: {
text: "@",
ondelete: "&"
},
link: function (scope, element, attrs) {
var w = $(element).outerWidth ();//应显示的宽度
var h = $(element).outerHeight();//应显示的高度
//按钮宽度
var btn_w = 60;
//设计按钮：
scope.btn = $('<div style="position:absolute;z-index:5998;right:0;top:0;width:'+btn_w+'px;height:'+h+'px;color:#fff;background-color:#900;text-align:center;padding-top:10px">'+(scope.text||'删除')+'</div>');
//改造行,用一个绝对定位div将内容包裹起来
$(element).contents().wrapAll('<div new_box style="position:absolute;z-index:5999;left:0;top:0;width:'+w+'px;height:'+h+'px;background-color:#fff;"></div>');
//添加按钮：
$(element).css({overflow:"hidden", position:"relative", "z-index":5999}).append(scope.btn)
//滑屏功能
