我有一个打开jquery UI对话框的按钮，按钮的侧面有2个位。如何移除这些？我应该在哪个文件中删除它们？谢谢

<a href="#" id="dialog-link" class="ui-state-default ui-corner-all"><button class='button'>Delete all</button></a>
    <div id="dialog" title="Are you sure?">Are you sure you want to delete?</div>

jquery

$( ".button" ).button();
$( "#dialog" ).dialog({
autoOpen: false,
width: 400,
buttons: [
    {
        text: "Delete all",
        click: function() {
            goToPage();
            $( this ).dialog( "close" );
        }
    },
    {
        text: "Cancel",
        click: function() {
            $( this ).dialog( "close" );
        }
    }
]
});
