js树中如何排列顺序排列的前缀数字？

Question

我正在使用 PHP 创建 js 树来显示文件夹和子文件夹名称，如下面的输出，我的问题是如何使前缀号可以按顺序显示在 js 树中：

下面是我的编码：

  <?php 
   $folderData = mysqli_query($mysql_con,"SELECT * FROM folder_category where status=1");

   $folders_arr = array();
   while($row = mysqli_fetch_assoc($folderData)){
      $parentid = $row['parentid'];
      if($parentid == '0') $parentid = "#";

      $selected = false;$opened = false;
      if($row['id'] == 2){
         $selected = true;$opened = true;
      }
      $folders_arr[] = array(
         "id" => $row['id'],
         "parent" => $parentid,
         "text" => $row['name'] . ' ' . "<span id='category'>". $row['category']."</span>",
         "state" => array("selected" => $selected,"opened"=>$opened) 
      );
   }

   ?>

   <!-- Initialize jsTree -->
   <div id="folder_jstree" title="JTM"></div>
   <!-- Store folder list in JSON format -->
   <textarea style="" id='txt_folderjsondata'><?= json_encode($folders_arr) ?></textarea>


<script style="text/javascript">
$(document).ready(function(){
   var folder_jsondata = JSON.parse($('#txt_folderjsondata').val());

   $('#folder_jstree').jstree({ 'core' : {
      'data' : folder_jsondata,
      'multiple': false
} });

var getColor = function (i) {
    if (i >= 100 && i <= 199) { return "blue"; }
    else if (i >= 200 && i <= 299) { return "red"; }
    else if (i >= 300 && i <= 399) { return "yellow"; }
    else if (i >= 400 && i <= 499) { return "purple"; }
    else if (i >= 500 && i <= 599) { return "green"; }
    else { return "#000"; }
}
var colorNodes = function(nodelist){
    var tree = $('#folder_jstree').jstree(true);
    nodelist.forEach(function (n) {
        tree.get_node(n.id).a_attr.style = "color:" + getColor(parseInt(n.text.substr(0,3),10));
        tree.redraw_node(n.id); //Redraw tree
        colorNodes(n.children); //Update leaf nodes
    });
}

$('#folder_jstree').bind('load_node.jstree', function (e, data) {
    var tree = $('#folder_jstree').jstree(true);
    colorNodes(tree.get_json());
});
});

  $( function() {
    $( document ).tooltip();
  } );



</script>

其实我想要的输出和下面的示例图一样，下面的示例图不是用编码制作的，只是我用画图软件编辑的，让你很容易理解我想要的得到输出：

下面json_encode($folders_arr)的结果：

Answer 1

jsTree 排序插件应该可以在这种情况下工作，您需要一个自定义排序比较器函数，因为默认函数会执行简单的字符串比较。

$('#folder_jstree').jstree({
  'core': {
    'data': folder_jsondata,
    'multiple': false
  },
  'plugins': ['sort'],
  'sort': function (a, b) {
        return this.get_text(a).localeCompare(this.get_text(b), 'en', { numeric: true });
    }
});

这是一个基于您的 jsFiddle
