Dojo ConfirmDialog隐藏取消按钮 [英] Dojo ConfirmDialog hiding cancel button
问题描述
我有一个dojo ConfirmDialog 如下：
I have a dojo ConfirmDialog as below:
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()
});
稍后基于某些条件，我正在更新 ConfirmDialog 动态如下：
Later on based on some condition, I am updating the ConfirmDialog dynamically as below:
this.myDialog.set("title", "New Title");
this.myDialog.set("content", "Its too late. Press ok to re-route.");
this.myDialog.set("buttonOk","Ok");
在此阶段，取消没有任何功能按钮。我如何隐藏它？
At this stage, I do not have any function for the Cancel button. How do I hide it?
以下任何一项工作：
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);
但这看起来并不正确。我想完全隐藏取消按钮。
But that does not look correct. I want to hide the Cancel button completely.
我该怎么办？
推荐答案
cancelButton 是按钮Dijit ，如果要隐藏/显示最后一个
，则必须通过简单地键入 this.myDialog.cancelButton.domNode
来访问它的domNode，使用 dojo / dom-style 隐藏/显示如下
The cancelButton is a button Dijit , if you want to hide / show this last ,
you've to access it's domNode by smply typing this.myDialog.cancelButton.domNode
and use the dojo/dom-style to hide /show as below
let cancelBtnDom = this.myDialog.cancelButton.domNode;
domStyle.set(cancelBtnDom, 'display', 'none');
请参阅以下工作摘要（使用外部按钮禁用启用）
see below working wnippet (disable enable using external button )
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);
});
});
