Question

我在功能上有删除按钮。当我单击DELETE时，将调用下面的函数并出现Confirm对话框，如果选择OK，则应删除文档，如果我取消，则应取消该文档。

console.log("before confirm dialog");

myDialog = new ConfirmDialog({
  title: "ConfirmDialog",
  content: "Are you sure? You want to delete document.",
  style: "width: 400px, color: green",
  onCancel: function(){
    //Called when user has pressed the Dialog's cancel button, to notify container.
    console.log("cancel");
  },
  onExecute: function(){
    //Called when user has pressed the dialog's OK button, to notify container.
    console.log("OK----");
    // getting error undefined for this function. How to call this ?
    this.onClickResetButton();
  }
});

  myDialog.show();
};

Answer 1

this.onClickResetButton() method inside `onExecute` is undefined because 'this' refers to the context of your dialog. i.e. it thinks that `onClickResetButton()` is a method which is part of `ConfirmDialog`

克服此问题的一种方法是定义一个变量（可以在构造函数中或在postCreate中）并为其分配“ this”

例如：let widgetRef=this;

稍后您可以在“ widgetRef.onClickResetButton()”内使用onExecute

如何从dojo ConfimDialog的OnExecute方法调用函数
