我重新发布这个问题是因为我在第一次发布它时犯了一个错误:我在提问之前没有努力尝试。我想向社区道歉,让他们为我做我的工作
我正在尝试按字母顺序对div中的无序列表进行排序。不是列表项在无序列表中,而是无序列表本身。
这是HTML的外观:
<div class="FindByCategory">
    <ul>
         <li> B. This is the first list item in the second unordered list</li>
         <li> B. This is the second list item in the second unordered list</li>
    </ul>
    <ul>
         <li> A. This is the first list item in the first unordered list</li>
         <li> A. This is the second list item in the first unordered list</li>
    </ul>
</div>我希望它看起来像这样:
<div class="FindByCategory">
    <ul>
         <li> A. This is the first list item in the first unordered list</li>
         <li> A. This is the second list item in the first unordered list</li>
    </ul>
    <ul>
         <li> B. This is the first list item in the second unordered list</li>
         <li> B. This is the second list item in the second unordered list</li>
    </ul>
</div>这就是我到目前为止所做的:
    <script>
        function sortUnorderedList(div.FindByCategory, sortDescending) {
  if(typeof div.FindByCategory == "string")
    div = document.getElementById(div.FindByCategory);
  var uls = ul.getElementsByTagName("UL");
  var vals = [];
  for(var i = 0, l = uls.length; i < l; i++)
    vals.push(uls[i].innerHTML);
  vals.sort();
  for(var i = 0, l = uls.length; i < l; i++)
    uls[i].innerHTML = vals[i];
}
$(function(){
    FindByCategory()
    }
    </script>发布于 2012-06-21 01:35:22
对任何DOM节点进行排序时,有三个简单的步骤:
在这种情况下,您想要排序的节点通过#FindByCategory > ul进行匹配,并且您可以有效地按其文本内容进行排序。所以:
var qsa = document.querySelectorAll("#FindByCateory > ul"), l = qsa.length, i, arr = [];
for( i=0; i<l; i++) {
    arr[i] = [qsa[i],qsa[i].textContent || qsa[i].innerText];
    // the text content is not readily accessible, since it depends on the browser
}
// now sort the array:
arr.sort(function(a,b) {return a[1] < b[1] ? -1 : (a[1] == b[1] ? 0 : 1);});
// and now re-append them
for( i=0; i<l; i++) {
    arr[i][0].parentNode.appendChild(arr[i][0]);
    // by re-appending the nodes, they will emerge sorted

尝尝这个
<script type="text/javascript">
                var array = new Array();
                for(var i = 0 ; i<4 ; i++){
                    var string = $("li:eq("+i+")").text();
                    array[i]  = string;
                }
                array.sort();
                alert(array);
