Question

我有以下工作正常，但我需要对其进行调整，以便将数据文件夹级别与小于或大于的数据进行比较。

$elem.nextUntil( $("li[data-folder-level="+level+"]"), "li" ).remove();

我试过了......

$elem.nextUntil( $("li[data-folder-level<="+level+"]"), "li" ).remove();

但这不起作用。

有什么想法吗？

示例html

<li data-folder-level="0"><a href="#">Hello world</a></li>
<li data-folder-level="1"><a href="#">Hello world</a></li>
<li data-folder-level="1"><a href="#">CLICK ME!!!!!!!!!!!!!!!</a></li>
<li data-folder-level="2"><a href="#">Will be removed...</a></li>
<li data-folder-level="2"><a href="#">Will be removed...</a></li>
<li data-folder-level="2"><a href="#">Will be removed...</a></li>
<li data-folder-level="3"><a href="#">Will be removed...</a></li>
<li data-folder-level="0"><a href="#">Hello world</a></li>
<li data-folder-level="0"><a href="#">Hello world</a></li>
<li data-folder-level="1"><a href="#">Hello world</a></li>
<li data-folder-level="0"><a href="#">Hello world</a></li>
<li data-folder-level="0"><a href="#">Hello world</a></li>
<li data-folder-level="1"><a href="#">Hello world</a></li>
<li data-folder-level="1"><a href="#">Hello world</a></li>
<li data-folder-level="1"><a href="#">Hello world</a></li>
<li data-folder-level="2"><a href="#">Hello world</a></li>
<li data-folder-level="2"><a href="#">Hello world</a></li>
<li data-folder-level="2"><a href="#">Hello world</a></li>

因此，点击列表中的第3个将删除接下来的4个列表项。

没有任何<=数据属性选择器，但您可以使用jQuery nextUntil和filter方法来检查您的后续元素data-attribute并相应地执行操作。< / p>

代码：

$("li").click(function () {
    var $elem = $(this);
    var level = $(this).attr("data-folder-level");
    $elem.nextUntil().filter(function () {
        return $(this).attr("data-folder-level") > level;
    }).remove();
});

由于您希望限制深度更改的删除，您可以使用each，如果发现更改，请使用return false停止。

代码：

$("li").click(function () {
    var $elem = $(this);
    var level = $(this).attr("data-folder-level");
    $elem.nextUntil().each(function () {
        if ($(this).attr("data-folder-level") <= level) {
            return false;
        } else {
            $(this).remove();
        }
    })
});

根据文档，nextUntil要求选择器或元素作为第一个参数。

但是，从jQuery 1.7开始，函数似乎也起作用了。所以你可以使用

$elem.nextUntil(function () {
  return $(this).attr("data-folder-level") <= level;
}, "li").remove();

$("ol").on("click", "li", function () {
  var level = +$(this).attr("data-folder-level");
  $(this).nextUntil(function () {
    return $(this).attr("data-folder-level") <= level;
  }, "li").remove();
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ol>
  <li data-folder-level="0"><a href="#">Hello world</a></li>
  <li data-folder-level="1"><a href="#">Hello world</a></li>
  <li data-folder-level="1"><a href="#">CLICK ME!!!!!!!!!!!!!!!</a></li>
  <li data-folder-level="2"><a href="#">Will be removed...</a></li>
  <li data-folder-level="2"><a href="#">Will be removed...</a></li>
  <li data-folder-level="2"><a href="#">Will be removed...</a></li>
  <li data-folder-level="3"><a href="#">Will be removed...</a></li>
  <li data-folder-level="0"><a href="#">Hello world</a></li>
  <li data-folder-level="0"><a href="#">Hello world</a></li>
  <li data-folder-level="1"><a href="#">Hello world</a></li>
  <li data-folder-level="0"><a href="#">Hello world</a></li>
  <li data-folder-level="0"><a href="#">Hello world</a></li>
  <li data-folder-level="1"><a href="#">Hello world</a></li>
  <li data-folder-level="1"><a href="#">Hello world</a></li>
  <li data-folder-level="1"><a href="#">Hello world</a></li>
  <li data-folder-level="2"><a href="#">Hello world</a></li>
  <li data-folder-level="2"><a href="#">Hello world</a></li>
  <li data-folder-level="2"><a href="#">Hello world</a></li>
</ol>

jQuery nextUntil属性小于或等于value
