jsTree显示/隐藏节点

问题描述

我正在使用jstree，如果可能，我想知道如何隐藏/显示节点。我给列表项目一个猫ID来选择他们与jQuery，但这是行不通的。

I'm working with jstree and I would like to know how to hide/show nodes if possible. I gave the list items a "cat" id to select them with jquery but this doesn't work.

以下是代码。

html：

<div class="resultsContent">

    <div class="demo" id="demo_1">

    <ul>

    {% for ipc in ipcs %}

        {% ifequal ipc.back_list 1 %}

            </ul></li>

        {% endifequal %}

        {% ifequal ipc.kind "c" %}

        <li id="{{ ipc.symbol }} cat" rel="node-type">
                {% else %}
                    <li id="{{ ipc.symbol }} cat" rel="node-type">
            {% endifequal %}
    {% endfor %}
    </ul>

</div>

</div>

script：

script:

jQuery('#demo_1')

    .jstree({

        plugins : [ "themes", "html_data", "checkbox"  ],

        themes : { theme: "default", dots : false, icons : false },

        core : { "initially_open" : [ "{{ top_symbol }}" ] },

    })

$("#cat").slice(5, 10).hide(); //Hide some nodes

推荐答案

您将生成一个ID元素，其ID由IPC符号值加上黑色空格，加上单词cat。

It seems at your code that you are generating li elements with an ID composed by a IPC Symbol value plus a black space, plus the word "cat".

<li id="{{ ipc.symbol }} cat" rel="node-type">

但是，您的选择器试图获取ID为cat的元素

But, your selector is trying to get an element whose ID is exactly "cat"

$("#cat").slice(5, 10).hide(); //Hide some nodes

也许你可以使用不同的jQuery选择器。例如，：

Maybe you could use a different jQuery selector. By the example, Attribute Contains Selector:

$("li[id*='cat']").slice(5, 10).hide(); //Hide nodes with the string 'cat'

或者，在这种情况下更合适（因为您正在查找整个单词）：

Or the Attribute Contains Word Selector, more appropriate in this case (because you are looking for a whole word):

$("li[id~='cat']").slice(5, 10).hide(); //Hide nodes containing the word 'cat'
