<div class="widget-content">
    <ul>
        <li><span class="label"> demo-text1 </span> Test Content</li>
        <li><span class="label"> demo-text2 </span> Test Content</li>
        <li><span class="label"> demo-text1 </span> Test Content</li>

        <li><span class="label"> demo-text2 </span> Test Content</li>
        <li><span class="label"> demo-text1 </span> Test Content</li>
        <li><span class="label"> demo-text2 </span> Test Content</li>
    </ul>
</div>

我想破坏这样的列表项:

<div class="widget-content">
    <ul class="demo-text1">
        <li><span class="label"> demo-text1 </span> Test Content</li>
        <li><span class="label"> demo-text1 </span> Test Content</li>
        <li><span class="label"> demo-text1 </span> Test Content</li>

    </ul> <!-- Break part 1 -->

    <ul class="demo-text2">
        <!-- Break part 2 -->
        <li><span class="label"> demo-text2 </span> Test Content</li>
        <li><span class="label"> demo-text2 </span> Test Content</li>
        <li><span class="label"> demo-text2 </span> Test Content</li>
    </ul>
</div>

我的意思是中断清单项目分为两个部分，例如第二个HTML示例.通过替换上面给出的class="label"示例中的文本(第二HTML)，将类添加到父级ul中.

I mean break list items in two parts like second HTML example. Add class to both parent ul by replace text find from class="label"example given above (second HTML).

如何仅通过jQuery/JS做到这一点?这是我尝试过的:

How can I do this simply by jQuery/JS ? Here is what I tried:

$(".widget-content").each(function() {
    var $li = $(this).find("li").unwrap(); // unwrap removes the old UL wrapper
    var uniq = [];

    // Create a collection of unique "label*" classes:
    $li.find("[class^=label]").attr("class", function(i, v) {
        if (!~$.inArray(v, uniq)) uniq.push(v);
    });
    // Group LI by A class, and wrap into a new UL with the same class
    $.each(uniq, function(i, klas) {
        $("a." + klas).closest("li").wrapAll($("<ul/>", {
            class: klas
        }));
    });
});

谢谢.

推荐答案

您可以使用.each()，$.each()，.html()，.text()，.trim()

var arr = []; // array to store `li` elements
var widget = $(".widget-content");

$(".widget-content li").each(function(index, el) {
  var html = el.outerHTML;
  // number at `label` text
  var curr = $(".label", this).text().trim().slice(-1);
  if (arr[curr - 1]) {
    arr[curr - 1].push(html)
  } else {
    arr[curr - 1] = [html];
  }
});

widget.html(""); // remove existing `html`

$.each(arr, function(key, val) {
  var li = val.join("");
  $(".widget-content").append($("<ul/>", {
    html: li,
    "class":$(li).eq(0).find(".label").text().trim()
  }))
})

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js">
</script>
<div class="widget-content">
  <ul>
    <li><span class="label"> demo-text1 </span> Test Content</li>
    <li><span class="label"> demo-text2 </span> Test Content</li>
    <li><span class="label"> demo-text1 </span> Test Content</li>

    <li><span class="label"> demo-text2 </span> Test Content</li>
    <li><span class="label"> demo-text1 </span> Test Content</li>
    <li><span class="label"> demo-text2 </span> Test Content</li>
  </ul>
</div>
