复选框到.detach然后.prepend对象

标签: javascript jquery checkbox prepend detach

我想使用.detach和.prepend复选框,我发现这个函数使用了两个按钮:

alert.requestWindowFeature(Window.FEATURE_NO_TITLE);

但是如何在复选框中使用它?当选中该复选框时,它会将elemento添加到正文中,并且取消选中时将分离该元素。

现在我正在使用淡入和淡出,但我想将其更改为分离和前置:

int divierId = alert.getContext().getResources()
                .getIdentifier("android:id/titleDivider", null, null);
View divider = alert.findViewById(divierId);
divider.setBackgroundColor(getResources().getColor(R.color.creamcolor));

这个怎么样: -

var x;
$('#toggle').change(function() {
  if (!this.checked)
    x = $('.content').detach();
  else
    $('body').append(x);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>   

<input type="checkbox" id="toggle" checked="true" />

<div class="content">
  content content content content content content content content content content content content
</div>

检查this示例是否有助于您获得清晰度。

    $(document).ready(function() {
      var p;
      $("#trigger").change(function() {
        if (this.checked) {
          $('#mydiv').prepend(p);
          p = null;
        } else {
          p = $("p").detach();
        }
      });
    });
      p {
        background: yellow;
        margin: 6px 0;
      }
      p.off {
        background: black;
      }

$(function () {
  var myCheck = $('input[name=myCheck]'),
      content = $('#content');
  myCheck.change(function(){
    if (myCheck.is(':checked')) {
      content.prependTo(document.body);
    } else {      
      content.detach();
    }
  });
});
