HTML Source Windows Do Not Close When The Message Compose Window Closes

by ADMIN 72 views

Introduction

When composing a new message in your email client, clicking on the "Source (HTML)" button opens a new window displaying the HTML source code of the message. However, when you close the message compose window, the HTML source window remains open, requiring manual closure. This article will guide you through a simple solution to automatically close the HTML source window when the message compose window is closed.

The Problem

When you click on the "Create a new message" button, followed by the "Source (HTML)" button, a new window opens displaying the HTML source code of the message. However, when you send the message or close the message compose window, the HTML source window remains open, leaving you with an extra window that needs to be manually closed.

The Solution

To solve this issue, we need to add a listener for the tabs onRemoved events. This listener will close the HTML source window when the message compose window is removed. We will achieve this by modifying the background.js file.

Modifying the background.js File

To add the listener for the tabs onRemoved events, we need to modify the init() function in the background.js file. We will add the following code at the bottom of the init() function:

browser.tabs.onRemoved.addListener((tabId, tabRemoveInfo) => closeHtmlEditor(tabId, tabRemoveInfo));

This code adds a listener for the tabs onRemoved events. When a tab is removed, the closeHtmlEditor() function will be called with the tabId and tabRemoveInfo as arguments.

Implementing the closeHtmlEditor() Function

We need to implement the closeHtmlEditor() function to close the HTML source window when the message compose window is removed. We will add the following code beneath the openHtmlEditor() function:

async function closeHtmlEditor(tabId, tabRemoveInfo) {
    if (openEditors.has(tabId)) {
        browser.windows.remove(openEditors.get(tabId)); // The existing windows onRemoved listener will delete from openEditors
    }
}

This code checks if the tabId is present in the openEditors object. If it is, the HTML source window is removed using the browser.windows.remove() method.

Other Suggestions

In addition to the solution above, there are a few other suggestions to improve the user experience:

  • Add a Save & Close Button: Adding a Save & Close button will allow users to save their changes and close the HTML source window in one step.
  • Add a Close Button: Adding a Close button will provide users with an easy way to close the HTML source window without having to manually close it.

Conclusion

In conclusion, adding a listener for the tabs onRemoved events and implementing the closeHtmlEditor() function will automatically close the HTML source window when the message compose window is closed. Additionally, adding a Save & Close button and a Close button will improve the user experience. By following these steps, you can resolve the issue of HTML source windows not closing when the message compose window is closed.

Implementation Details

Here is the complete code for the background.js file:

// ...

async function init() {
    // ...

    browser.tabs.onRemoved.addListener((tabId, tabRemoveInfo) => closeHtmlEditor(tabId, tabRemoveInfo));
}

async function openHtmlEditor(tabId) {
    // ...

    const htmlEditor = await browser.windows.create({
        url: 'html-editor.html',
        type: 'popup',
        width: 800,
        height: 600,
    });

    openEditors.set(tabId, htmlEditor.id);
}

async function closeHtmlEditor(tabId, tabRemoveInfo) {
    if (openEditors.has(tabId)) {
        browser.windows.remove(openEditors.get(tabId)); // The existing windows onRemoved listener will delete from openEditors
    }
}

// ...
