我的问题是如何通过从列表项文本中添加类查找来包装/中断列表项,如下所示?
我在这里的相关问题是:Wrap List elements by class name
<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>
我想打破这样的列表项:
<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>
我的意思是分组项目分为两部分,如第二个HTML示例。通过替换上面给出的ul
示例中的文本find(第二个HTML),将类添加到父class="label"
。
我怎样才能通过jQuery / JS来做到这一点?这是我试过的:
$(".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
}));
});
});
提前致谢。

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()
}))
})
