j查询排序多个 DIV(如果包含文本)<span>

Question

我有多个部分，如果其中包含<span>文本，我想在其中对DIVs进行排序。我尝试了不同的stackoverflow线程，但到目前为止对我没有任何帮助，我离我的目标有点接近，但我的代码不起作用，我不确定我做错了什么，这些内部div 需要在每个部分内排序。但我不擅长JS。 如果div 包含范围文本，则在每个部分中将其排在第一位。

sortUsingNestedText($('#toSort'), "div.customCardData", "span.recenUpdate");
function sortUsingNestedText(parent, childSelector, keySelector) {
var items = parent.children(childSelector).sort(function(a, b) {
var vA = $(keySelector, a).text();
var vB = $(keySelector, b).text();
return (vA < vB) ? -1 : (vA > vB) ? 1 : 0;
});
parent.append(items);
console.log("done");
}

</div>
</div>

这是我的jsFiddle

Answer 1

首先请注意，您已经创建了具有相同idtoSort的多个元素。这是无效的id因为 DOM 中必须是唯一的。如果要按常见行为对元素进行分组，请改用类。

我想在每个部分中先带一个跨度

在这种情况下，您不需要排序。只需将相关divappend()到他们组的开头：

$('.toSort').each(function() {
var $h2 = $(this).find('h2');  
$(this).find('.customCardData:has(span.recenUpdate)').insertAfter($h2);
});
