javascript - 单击图像右上角的 "X"标记删除图像

Question

我想通过单击图像右上角的“X”标记来删除图像，我遵循了 CSS 的这个 fiddle http://jsfiddle.net/yHNEv/ .

HTML代码:

 <div class="img-wrap">
  <span  ng-click="deleteLocalfile()" class="close">&times;</span>
  <a id="div2" href><img ng-src="{{imagepreviewUrl}}" style="width: 100px; height: 100px;" alt=""></a>
</div>

Controller 代码:

 $scope.deleteLocalfile = function(){

  var result = document.getElementsByClassName("close");
  var wrappedResult = angular.element(result);

  wrappedResult.remove();

}

上面的代码在点击它时删除了“X”标记，而不是图像，但是在点击“X”之后我在这里得到了一个事件。

第二种方法:

 <div class="img-wrap">
  <span   class="close">&times;</span>
  <a  ng-click="deleteLocalfile()" id="div2" href><img ng-src="{{imagepreviewUrl}}" style="width: 100px; height: 100px;" alt=""></a>
</div>

第二种方法 Controller 代码

$scope.deleteLocalfile = function(){
var result = document.getElementsById("div2");
 var wrappedResult = angular.element(result);
 wrappedResult.remove();
}

这里我没有获得点击“X”标记的事件，获得图像点击事件仅删除保留“X”标记的图像。

这实质上是 Sasikumar 的答案重写为不使用 jQuery。

var closeBtns = document.querySelectorAll('.img-wrap .close')

for (var i = 0, l = closeBtns.length; i < l; i++) {
  closeBtns[i].addEventListener('click', function() {
    var imgWrap = this.parentElement;
    imgWrap.parentElement.removeChild(imgWrap);
  });
}

.img-wrap {
  position: relative;
  display: inline-block;
  border: 1px red solid;
  font-size: 0;
}
.img-wrap .close {
  position: absolute;
  top: 2px;
  right: 2px;
  z-index: 100;
  background-color: #FFF;
  padding: 5px 2px 2px;
  color: #000;
  font-weight: bold;
  cursor: pointer;
  opacity: .2;
  text-align: center;
  font-size: 22px;
  line-height: 10px;
  border-radius: 50%;
}
.img-wrap:hover .close {
  opacity: 1;
}

<div class="img-wrap">
  <span class="close">&times;</span>
  <img src="http://images.freeimages.com/images/premium/previews/2282/2282459-fisheye-tank.jpg" width="200" data-id="123">
</div>

<div class="img-wrap">
  <span class="close">&times;</span>
  <img src="http://images.freeimages.com/images/previews/38a/kendo-armor-3-1431999.jpg" width="100" data-id="103">
</div>
