通过将文本替换为类来换行/拆分列表元素 [英] Wrap/Break List elements by replace text to class

问题描述

我的问题是如何通过从列表项文本中添加类查找来包装/拆分列表项，示例如下?
我的相关问题在这里:按类名包装列表元素

小提琴链接

<ul><li><span class="label">demo-text1 </span>测试内容<li><span class="label">demo-text2 </span>测试内容<li><span class="label">demo-text1 </span>测试内容<li><span class="label">demo-text2 </span>测试内容<li><span class="label">demo-text1 </span>测试内容<li><span class="label">demo-text2 </span>测试内容

我想像这样分解列表项:

<ul class="demo-text1"><li><span class="label">demo-text1 </span>测试内容<li><span class="label">demo-text1 </span>测试内容<li><span class="label">demo-text1 </span>测试内容<!-- 打破第 1 部分 --><ul class="demo-text2"><!-- 打破第 2 部分 --><li><span class="label">demo-text2 </span>测试内容<li><span class="label">demo-text2 </span>测试内容<li><span class="label">demo-text2 </span>测试内容

我的意思是将列表项分成两部分，例如第二个 HTML 示例.通过替换上面给出的 class="label" 示例(第二个 HTML)中的文本查找，将类添加到父 ul.

我怎样才能简单地通过 jQuery/JS 做到这一点?这是我尝试过的:

$(".widget-content").each(function() {var $li = $(this).find("li").unwrap();//unwrap 移除旧的 UL 包装器var uniq = [];//创建一组独特的label*"类:$li.find("[class^=label]").attr("class", function(i, v) {if (!~$.inArray(v, uniq)) uniq.push(v);});//将 LI 按 A 类分组，并包装成具有相同类的新 UL$.each(uniq, function(i, klas) {$("a." + klas).closest("li").wrapAll($("<ul/>", {班级:克拉斯}));});});

提前致谢.

解决方案

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

var arr = [];//存储`li`元素的数组var widget = $(".widget-content");$(".widget-content li").each(function(index, el) {var html = el.outerHTML;//`label` 文本中的数字var curr = $(".label", this).text().trim().slice(-1);如果 (arr[curr - 1]) {arr[curr - 1].push(html)} 别的 {arr[curr - 1] = [html];}});小部件.html("");//删除现有的`html`$.each(arr, function(key, val) {var li = val.join("");$(".widget-content").append($("
", {html:李，"class":$(li).eq(0).find(".label").text().trim()}))})

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

My question is how to Wrap/Break list items by add Class find from list items text, example below?

Fiddle link

<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>

I want to break list items like this:

<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>

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).

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
        }));
    });
});

Thanks in advance.

解决方案

You can use .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>
