can jsTree use radio check

i know there is a plugin for jsTree named jquery.tree.checkbox.js. that make the tree node multi checkable.

i just wondered if there is a plugin to raido check the tree node? or how can i modify jquery.tree.chec开发者_JAVA百科kbox.js to achieve that?

This can simply be done by adding the attribute

    rules:{
            multiple : false
          } 

Inside the configuration of the tree. This will make it impossible to choose multiple entries.

@Asaf's answer seems to no longer work on version 3.3.1 in 2016. You now need to set multiple on core:

$jstree.jstree({
    core: {
        multiple: false,
        ...
    }
});

Setting multiple:false will still allow cascading so you need to turn that off too.

version 3.3.3

$(".tree").jstree({
    plugins: ["checkbox"],
    core: {
        data: ...,
        multiple: false
    },
    checkbox: {
        three_state: false,
        cascade: "none"
    }
});

The radio button option is still not released, so you have to change the chceckbox option as single select.

bind('check_node.jstree', function(e, data) {
    var currentNode = data.rslt.obj.attr("id");
    $("#tree").jstree("get_checked",null,true).each 
        (function () { 
            if(currentNode != this.id){
                jQuery.jstree._reference($("#tree")).uncheck_node('#'+this.id);
            }
        }); 
});

Using jsTree version 3.2.1 with the checkbox plugin it is possible to emulate radiobutton behaviour handling the 'changed' event as follows:

//jstree configuration:
'checkbox': {
    three_state: false, //required for the cascade none to work
    cascade: 'none' //no auto all_children<->parent selection
},
//...

var resetting = false;
$('#tree').on('changed.jstree', function (e, data) {
    if (resetting) //ignoring the changed event
    {
        resetting = false;
        return;
    }
    if ($("#multiselect").is(':checked') == false && data.selected.length > 1) {
        resetting = true; //ignore next changed event
        data.instance.uncheck_all(); //will invoke the changed event once
        data.instance.check_node(data.node/*currently selected node*/);
    }
});
