How to close the current window in vue

Vue is a popular front-end framework widely used in web development. When using Vue to develop projects, you often need to interact with windows, such as opening, closing, transferring data, etc. This article will introduce how to close the current window in Vue.

1. Use window.close()

In traditional Web development, the most common way to close the current window is to use the window.close() method. In Vue, we can use this method directly in the component to close the current window.

For example, we can use the following code in a button click event:

<button @click="closeCurrentWindow">关闭窗口</button>

...

methods: {
    closeCurrentWindow() {
        window.close();
    },
}

Here by calling the closeCurrentWindow() method in the button click event, and then using window.close() Close the current window.

It should be noted that the following conditions must be met when using the window.close() method:

• The current window must be opened by JavaScript.
• The current window must be controlled by a script.
• If the current window is a top-level window (has no parent window), the window cannot be closed.

2. Using window.opener

In addition to using the window.close() method, we can also use the window.opener property to close the current window. The window.opener property points to the window object that opens the current window, through which we can interact.

For example, we can define a closeCurrentWindow() method in the parent window and pass it to the child window. The child window can call the method in the parent window through window.opener to close the current window.

Parent window:

<template>
    <div>
        <button @click="openNewWindow">打开新窗口</button>
    </div>
</template>

<script>
export default {
    methods: {
        openNewWindow() {
            window.open('newWindow.html', '_blank');
        },
        closeCurrentWindow() {
            window.close();
        }
    }
}
</script>

Child window:

<template>
    <div>
        <button @click="closeWindow">关闭窗口</button>
    </div>
</template>

<script>
export default {
    methods: {
        closeWindow() {
            window.opener.closeCurrentWindow();
        }
    }
}
</script>

In the child window, we call the closeCurrentWindow() method in the parent window through window.opener to close the current window.

It should be noted that there are some limitations in using the window.opener attribute. For example, compatibility issues may occur in some browser environments.

3. Using Vue Router

When using Vue to develop a single-page application, we usually use Vue Router to manage routing. In Vue Router, the function of closing the current window can be implemented programmatically.

For example, in a routing component, we can use the $router.go() method to return the previous route, that is, close the current window. The code is as follows:

<template>
    <div>
        <button @click="closeWindow">关闭窗口</button>
    </div>
</template>

<script>
export default {
    methods: {
        closeWindow() {
            this.$router.go(-1);
        }
    }
}
</script>

It should be noted that when using the $router.go() method to close the window, the following conditions need to be met:

• The current window must be a single-page application of a route.
• The current route must have a previous history record before you can use the $router.go() method to return the previous route and close the current window.

Summary

This article introduces three methods to close the current window in Vue:

1. Use the window.close() method
2. Use window.opener property
3. Use Vue Router to programmatically close routing

Among them, the window.close() method is the simplest method, but it also has some limitations. Both the window.opener property and Vue Router can handle these limitations better and provide a more flexible interaction method. Readers can choose the method that best suits them to close the current window according to their specific needs.
