<a href="#" id="open">open</a>

// javascript
$(document).ready(function() {
    $('#open').click(function() {

    });
    $("#dialog").dialog({
        autoOpen: false,
        height: 400,
        width: 350,
        modal: true,
        open: function() {
            var dialog = $(this);
            console.log('dialog', dialog);
            var buttons = dialog.dialog("option", "buttons");
            console.log('buttons', buttons);
            //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");
            }
        }]
    });
});

Answer 1

最简单的方法是抓住 当前对话框的widget元素 和.find()里面的按钮：

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

^{比找到页面上的所有button元素并猜测哪一个是哪个元素更容易。}

我刚刚在按钮上添加了一个id，并更新了点击功能以隐藏它。

$(document).ready(function () {

    $('#open').click(function () {
        $("#dialog").dialog("open");
        $("#save").hide();
    });

    $("#dialog").dialog({
        autoOpen: false,
        height: 400,
        width: 350,
        modal: true,
        open: function () {
            var dialog = $(this);
            console.log('dialog', dialog);
            var buttons = dialog.dialog("option", "buttons");
            console.log('buttons', buttons);
            //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',
            id: "save",
            click: function () {
                alert('save');
                $(this).dialog("close");
            }
        }, {
            text: 'CANCEL',            
            click: function () {
                $(this).dialog("close");
            }
        }]
    });

});
