下面的代码在Jquery ui对话框中给出了太多的递归错误

$( "#dialog-confirm" ).dialog({
        resizable: false,height:140,modal: true,buttons: {
            "Delete all items": function() {
                $( this ).dialog( "close" );
            },Cancel: function() {
                $( this ).dialog( "close" );
            }
        },close:function(){
                       $( this ).dialog( "close" );
                }
    });

如何解决这个问题？
