jsTree的checkbox默认选中和隐藏

jstree复选框自定义显示隐藏和初始化默认选中

首先需要配置 Checkbox plugin

"plugins" : ['checkbox']

设置默认选中状态（checkbox 选中）

state: {checked: true}

$.jstree.defaults.checkbox.tie_selection

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'],
    "checkbox" : {
        "tie_selection": false,
    }
});

jstree复选框自定义显示隐藏

jstree 本身不支持在节点中隐藏 checkbox，国外有个大佬给出一个利用 css 来隐藏的解决方案：

首先来一段 css

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

然后在 data 的 json 数据结构中

$('#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
