easyui tree：根据属性格式化树节点名称

$('#resourceTree').tree({
    method : 'post',
    animate : true,
    onContextMenu : function(e, node) {
        e.preventDefault();
        $(this).tree('select', node.target);
        $('#resourceContextMenu').menu('show', {
            left : e.pageX,
            top : e.pageY
        });
    },
    formatter : function(node) {
        // 格式化节点名称
        var nodeText = node.text;
        if (node.attribute.resType == '2') {
            // 权限
            nodeText += "(" + node.attribute + permission + ")";
        }
        if (node.attribute.isValid == '0') {
            // 权限
            nodeText = "<font color='blue'>" + nodeText + "</font>";
        }
        return nodeText;
    }
});
