jstree的checkbox默認選中和隱藏

jstree複選框自定義顯示隱藏和初始化默認選中

首先須要配置 Checkbox plugin

"plugins" : ['checkbox']

設置默認選中狀態（checkbox 選中）

state: {checked: true}

示例：

$('#demo_tree').jstree({
    "core" : {
        'data': [
           { "id" : "ajson1", "parent" : "#", "text" : "Simple root node", state: {checked: true}},
           { "id" : "ajson2", "parent" : "#", "text" : "Root node 2" },
           { "id" : "ajson3", "parent" : "ajson2", "text" : "Child 1" },
           { "id" : "ajson4", "parent" : "ajson2", "text" : "Child 2" },
        ]
    },
    "plugins" : ['checkbox'],
});

jstree複選框自定義顯示隱藏

jstree 自己不支持在節點中隱藏 checkbox，國外有個大佬給出一個利用 css 來隱藏的解決方案：

首先來一段 css

.no_checkbox>i.jstree-checkbox{display:none}

而後在 data 的 json 數據結構中

$('#demo_tree').jstree({
    "core" : {
        'data': [
           { "id" : "ajson1", "parent" : "#", "text" : "Simple root node", state: {checked: true}},
           { "id" : "ajson2", "parent" : "#", "text" : "Root node 2" },
           { "id" : "ajson3", "parent" : "ajson2", "text" : "Child 1" , a_attr: {class: "no_checkbox"}},
           { "id" : "ajson4", "parent" : "ajson2", "text" : "Child 2" },
        ]
    },
    "plugins" : ['checkbox'],
});

效果：

 

jstree version => 3.3.8
