dialog.showMessageBox 不返回电子 main.js 中的按钮索引 [英] dialog.showMessageBox not returning button index in electron main.js
问题描述
我有一个消息框，当用户单击dashboardWindow 上的关闭时会打开一个消息框(Windows 操作系统右上角的X 按钮)
I have a messagebox that will open when the user click close on dashboardWindow (X button top right on windows os)
dashboardWindow.on("close", (event) => {
event.preventDefault();
console.log("before message box");
dialog.showMessageBox(
dashboardWindows,
{
message: "Test",
buttons: ["Default Button", "Cancel Button"],
defaultId: 0, // bound to buttons array
cancelId: 1 // bound to buttons array
},
(response) => {
if (response === 0) {
// bound to buttons array
console.log("Default button clicked.");
} else if (response === 1) {
// bound to buttons array
console.log("Cancel button clicked.");
}
}
);
console.log("after message box");
});
}
当我关闭 dashboardWindow 时消息框打开，但我无法让 response === 0 工作.即使没有点击按钮，console.log("after message box"); 也已经运行.我怎样才能做出响应(messageBox 上的返回索引按钮)?
The messagebox opened when i close the dashboardWindow but i can't get response === 0 to work. Samehow console.log("after message box"); already run even when there is no click on the buttons. How I can make the response work (return index button on messageBox)?
推荐答案
请参考最新的 API 文档关于 dialog.showMessageBox:此方法返回一个 Promise 对象并且不再使用回调函数，就像在 Electron v5.xx 之前一样
Please refer to the most recent API doc about dialog.showMessageBox: this method returns a Promise object and doesn't make use of a callback function any more, like it used to until Electron v5.x.x.
Returns Promise - 使用包含以下属性:
Returns
Promise<Object>- resolves with a promise containing the following properties:
responseNumber - 点击按钮的索引.checkboxChecked布尔值 - 如果设置了checkboxLabel，则复选框的选中状态.否则false.
responseNumber - The index of the clicked button.checkboxCheckedBoolean - The checked state of the checkbox ifcheckboxLabelwas set. Otherwisefalse.
这应该可以工作(尽管在您的上下文中未经测试):
This should work then (untested in your context though):
dashboardWindow.on("close", (event) => {
event.preventDefault();
console.log("before message box");
dialog.showMessageBox(
dashboardWindows,
{
message: "Test",
buttons: ["Default Button", "Cancel Button"],
defaultId: 0, // bound to buttons array
cancelId: 1 // bound to buttons array
})
.then(result => {
if (result.response === 0) {
// bound to buttons array
console.log("Default button clicked.");
} else if (result.response === 1) {
// bound to buttons array
console.log("Cancel button clicked.");
}
}
);
console.log("after message box");
});
