            //Change names this way...
            buttons[0].text = 'Save2';
            buttons[1].text = 'Cancel2';
            dialog.dialog("option", "buttons", buttons);
            //How do I hide a button (i.e. hide Save button)?
        },
        buttons: [{
            text: 'SAVE',
            click: function() {
                alert('save');
                $(this).dialog("close");
            }
        }, {
            text: 'CANCEL',
            click: function() {
                $(this).dialog("close");

        }]
    });
});

推荐答案

最简单*的方法是保留当前对话的

The easiest* way is to get a hold of the current dialog's widget element and .find() the button inside it:

open: function () {
    var $widget = $(this).dialog("widget");
    $widget.find(".ui-dialog-buttonpane button:first").hide();
}

更新的小提琴

^{比在页面上找到所有button元素并猜测哪个元素更容易.}

^{Easier than finding all the button elements on the page and guessing which one is which.}
