$("#ifTree").jstree({
            "plugins" : ["themes","html_data","ui","crrm"], 
            "themes" : {
                    "theme" : "apple",
                    "dots" : true,
                    "icons" : false
            }           
    });

    $("#createIf_c").click(function () { 
        $("#ifTree").jstree("create",null,"inside",  { "data" :{ title:"if",value:"expression"} },
                function() {}, true);
    });
$("#display").click(function(){
            var a = $.jstree._focused().get_selected();
            alert(a.attr("value"));
    });

在上面的代码中,我创建了一个 jstree,单击 ID 为 #createIf_c 的按钮后,我添加了一个标题为“if”的节点,但由于我希望更多数据与该节点相关联,因此我添加了更多属性给它在创建节点时。接下来,当我尝试访问此关联数据时,此处为“值”,然后我收到警报“未定义”。那么是否有不同的方式将数据与节点相关联?或者访问节点关联数据的另一种方式是jstree?..请帮助....

你可以把你的额外数据放在 JSON node.data这没有记录

请参考作者的回答

您可以通过 编辑信息$('#tree').jstree(true).get_node("some_node_id"),并通过 将额外数据作为 json 发布$('#tree').jstree(true).get_json("some_node_id")

You can add anything you want to the data object. Like:
{ "id" : "some_node_id" "text" : "some node", ... "data" : { "foo" : "bar", "example_array" : ["1",2,true], "obj" : {"asdf":"asdf1"}  } ...

And later on you can retrieve it like so:
$('#tree').jstree(true).get_node("some_node_id").data.obj.asdf; // this would equal "asdf1"
$('#tree').jstree(true).get_node("some_node_id").data.example_array; // this would be an array: ["1",2,true]

Setting other values is just as simple - you are working with a normal object:
$('#tree').jstree(true).get_node("some_node_id").data.obj.asdf = "some other value";
$('#tree').jstree(true).get_node("some_node_id").data.example_array = "I do not want this an array anymore";
$('#tree').jstree(true).get_node("some_node_id").data.obj.new_property = 1024;

最简单的方法就是向 html 元素添加属性,即

    var node = $.jstree._focused().get_selected(); //get the selected node or which ever you want the data to be associated with
    node.attr("expression","xyz"); //add an attribute (name,value) here, name-expression and value-xyz

将数据关联到节点的正确方法如下:

如果您要添加更多数据,即属性,则在“attr” 属性下提到所有属性(名称、值)

属性”:{属性名称1:“属性值1”,属性名称2:“属性值2”……}

 $("#createIf_c").click(function () { 
 $("#ifTree").jstree("create",null,"inside",
   { "data" : "testNodeName", 
      "attr": { title:"if",value:"expression"} },  function() {}, true);
});

使用 jstree v3,您可以使用插件关联属性,如下所示:-

// create instance
var inst = $("#tree-id").jstree();
// create node definition
var node = {
    id: "new_node_id",
    text: "New Node",
    li_attr: { "data-files": "false" },
    a_attr: { "data-url": "some_url" }
};
// create node
var newNodeId = inst.create_node("#", node);

节点参数的预期格式(来自源注释):

// Expected format of the node (there are no required fields)
//{
//  id: "string" // will be autogenerated if omitted
//  text: "string" // node text
//  icon: "string" // string for custom
//  state: {
//      opened: boolean  // is the node open
//      disabled: boolean  // is the node disabled
//      selected: boolean  // is the node selected
//  },
//  children: []  // array of strings or objects
//  li_attr: { }  // attributes for the generated LI node
//  a_attr: { }  // attributes for the generated A node
//}

以及create_node参数的预期格式:

// create_node(par, node, pos, callback, is_loaded)

// par (object) - the parent node (to create a root node use "#" (string) or `null`)
// node (object) - the data for new node (valid JSON object, or a simple string with the name)
// pos (object) - index to insert the node, "first" and "last" are supported, default is "last"
// callback (function) - a function to be called once the node is created
// is_loaded (boolean) - internal argument indicating if the parent node was succesfully loaded

// returns (string) - the ID of the newly create node

要关联来自 HTML 定义的数据:

如果要使用树的 HTML 定义关联数据,请使用:

<li id="treesiteadmin-serverStatus" data-ic='{"form":"site.serverstatus"}' data-jstree='{"icon":"glyphicons glyphicons-server"}'>Stato del server</li>

当前选定节点的“数据”属性将是:

{"jstree":{"icon":"glyphicons glyphicons-server"},"ic":{"form":"site.serverstatus"}}

查看结果 - 选定节点的“数据”属性

div id="tree_1" class="tree-demo">
    <ul>
        <li data-jstree='{ "opened" : false }' id="c67"> Sıcak İçecekler
            <ul>

                <li data-jstree='{ "type" : "file", "selected" : false }' id="501">Fincan Çay</li>

            </ul>
        </li>
        <li data-jstree='{ "opened" : true }' id="c68"> Soğuk İçecekler
            <ul>
                <li data-jstree='{ "type" : "file", "selected" : true }' id="514">Ayran</li>
                <li data-jstree='{ "type" : "file", "selected" : true }' id="515">Kola</li>
                <li data-jstree='{ "type" : "file", "selected" : true }' id="516">Meyveli Gazoz</li>                    
            </ul>
        </li>
    </ul>
</div>

<ul>如果你想通过and<li>元素来解决它,这个 html 非常适合自定义 id 。
