easyui tree 级联从三种状态变为两种状态

$(‘#tree‘).tree({
   url: ‘/tree‘
　　,lines:false
   ,checkbox:true
   ,cascadeCheck: false
   ,onCheck: function (node, checked) {
       blChild(node,checked);
  　　　blParent(node,checked);
　　}

});

function blChild(node, checked){
    var children = node.children;
    if(children.length>0){
        for(var i=0;i<children.length;i++){
            var childNode = children[i];
            //childNode = $(‘#tree‘).tree(‘find‘, childNode.id);//当树没加载好，修改报iconCls错时加上这行即可
            if(checked){
                $(‘#tree‘).tree(‘update‘, {
                    target:childNode.target,
                    checked:true
                });
            }else{

                });
            }
