Dojo ConfirmDialog 隐藏取消按钮

Question

我有一个道场 ConfirmDialog 如下：

this.myDialog = new ConfirmDialog({
                   title: "My Dialog",
                   content: "Do you want to continue?",
                   class: "confirmDialog",
                   closable: false
                });

// change button labels
this.myDialog.set("buttonOk","Yes");
this.myDialog.set("buttonCancel","No");

// register events
this.myDialog.on("execute", function() { 
                              self.continueSomething() 
                            });

稍后根据某些情况，我正在动态更新 ConfirmDialog，如下所示：

this.myDialog.set("title", "New Title");
this.myDialog.set("content", "Its too late. Press ok to re-route.");
this.myDialog.set("buttonOk","Ok");

在这个阶段，Cancel 按钮没有任何功能。我该如何隐藏它？

None 以下作品：

this.myDialog.cancelButton.hide();
//or
this.myDialog.cancelButton.set("display", "none");
//or 
this.myDialog.cancelButton.set("display", none);

我可以将其禁用为：

this.myDialog.cancelButton.set("disabled", true);

但这看起来不正确。我想完全隐藏 Cancel 按钮。

我该怎么做？

cancelButton是一个button Dijit，如果你想隐藏/显示最后一个，你必须通过简单地输入 this.myDialog.cancelButton.domNode 来访问它的 domNode 并使用 dojo/dom-style 隐藏/显示如下

let cancelBtnDom = this.myDialog.cancelButton.domNode;
domStyle.set(cancelBtnDom, 'display', 'none');

请参阅下面的工作 wnippet（使用外部按钮禁用启用）

require(["dijit/ConfirmDialog", "dojo/dom-style", "dojo/domReady!"], function(ConfirmDialog, domStyle){
    myDialog = new ConfirmDialog({
        title: "My ConfirmDialog",
        content: "Test content.",
        style: "width: 300px"
    },"dialog");
    
    let cancelBtn = myDialog.cancelButton.domNode;
    
    let switchBtn = document.getElementById("switch");
    
    switchBtn.addEventListener("click",function(){
     let display = domStyle.get(cancelBtn, "display") !== "none" ?  "none" : "";
     console.log(display);
      domStyle.set(myDialog.cancelButton.domNode, 'display', display);
    });
    
});

<link href="//ajax.googleapis.com/ajax/libs/dojo/1.10.4/dijit/themes/claro/claro.css" rel="stylesheet" />

<body class="claro">
  <div class="dialog"></div>
  <button onclick="myDialog.show();">show</button>
  <button id="switch" >enable/Disable cancel button</button>
</body>
