如何查看jquery中的条件?

How to check the condition in the jquery?

我正在创建 js 树来显示文件夹路径名称,我的问题是如果数据库 table status 为 0(不活动),如何检查条件然后将在 js 树中显示 line-through。 Else table status is 1(active) 刚刚恢复正常。以下是我的编码:

<?php 
   $folderData = mysqli_query($mysql_con,"SELECT * FROM filing_code_management");
   $folders_arr = array();
   while($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>",
         "category" => $row['category'],
         "status" => $row['status'], // status 0 is inactive, status 1 is active
         "state" => array("selected" => $selected,"opened"=>$opened) 

      );
   }

   ?> 

<script style="text/javascript">
    var StrikeNodes = function(nodelist) {
      var tree = $('#folder_jstree').jstree(true);
      nodelist.forEach(function(n) {
        tree.get_node(n.id).a_attr.style = "text-decoration:" + getStrike(parseInt(n.text.substr(0, 3), 10));
        tree.redraw_node(n.id); //Redraw tree
        StrikeNodes(n.children); //Update leaf nodes
      });
    };

        var getStrike = function(i) {
      if (status = '0' ) {
        return "line-through;";
      }  else {
        return "";
      }
    };

    $('#folder_jstree').bind('load_node.jstree', function(e, data) {
      var tree = $('#folder_jstree').jstree(true);
      StrikeNodes(tree.get_json());
    });
</script>

现在我的输出显示了 js 树中的所有直通,而不是检测哪个是活动的或非活动的。

希望有人能指导我哪里错了。

查看您的代码。你没有比较它应该是 status == '0' 而不是 status = '0'

的状态

还有jstree提供的可用选项。 data 选项这可以是任何你想要的。它是您想要附加到点头的元数据。您以后可以随时访问和修改它 - 它对节点的视觉效果没有影响。

[{
    "id": "1",
    "parent": "#",
    "text": "100 PENTADBIRAN <span id='category'>JTM<\/span>",
    "category": "JTM",
    "data": { "status": 0 },
    "state": {
        "selected": false,
        "opened": false
    }
}]

var StrikeNodes = function(nodelist) {
  var tree = $('#folder_jstree').jstree(true);
  nodelist.forEach(function(n) {
      tree.get_node(n.id).a_attr.style = "text-decoration:" + getStrike(n.data.status);
      tree.redraw_node(n.id); //Redraw tree
      StrikeNodes(n.children); //Update leaf nodes
  });
};

var getStrike = function(status) {
    if (status == 0) {
       return "line-through;";
    }
    return "";
};
