This code appears to be an HTML page containing some JavaScript functions. Let's break down its functionality step by step:

  1. <script> Tag: The code begins with a <script> tag containing JavaScript functions. These functions are meant to be executed when certain events occur.

  2. postForm() Function: This function is defined to set the action of the frmMain form element to a specific URL (https://scanner-api.crucial.com/scanner/webhook.aspx) and then submit the form. In other words, when called, this function will send a POST request to the specified URL with the data contained in the form.

  3. timedRefresh() Function: This function is intended to trigger a page refresh after a certain timeout period. It uses the setTimeout() function to schedule a page reload using the location.reload(true) command. The true argument for reload() indicates that the page should be reloaded from the server, not from the cache.

  4. <body> Tag: The onload attribute of the <body> tag is set to javascript:timedRefresh(6000);. This means that when the page finishes loading, the timedRefresh() function will be called with an argument of 6000 milliseconds (6 seconds). So, the page will automatically reload every 6 seconds.

  5. <form> Element: The code defines a form with the id and name attributes set to 'frmMain'. This form is intended to submit data.

  6. <input> Elements: Inside the form, there are several hidden input elements. These elements are used to hold data that will be sent when the form is submitted.

    • ScanData, ScanType, and ScanStatus: These hidden input elements have predefined values, which seem to be related to a scanning process. For example, ScanType might indicate the type of scan being performed.

    • appName and ComputerType: These hidden input elements also have predefined values that provide information about the scanning application and the type of computer.

  7. <img> Tag: This tag includes an image sourced from 'https://content.crucial.com/content/dam/crucial/web-ui/scanner/scanner-loading-image.gif'. The image is displayed centered on the page. This image might serve as a loading animation or visual feedback to the user.

In summary, this code creates a webpage that automatically reloads every 6 seconds. It contains a form with hidden input fields that seem to be related to a scanning process, and there are JavaScript functions for submitting the form data to a specific URL and triggering the page reload. The code is likely part of a system that performs some kind of scanning operation and provides a user interface for it.

On some computers where I run this it seems that the page is stuck on step 7 forever. On other computers it will pull and display a page from the crucial.com website. Any idea what might be going on there?

Certainly, the behavior you're describing could be caused by a few different factors. Here are a few potential reasons for the discrepancies in behavior on different computers:

  1. Network Connectivity: The code contains an image (<img>) sourced from 'https://content.crucial.com/content/dam/crucial/web-ui/scanner/scanner-loading-image.gif'. If the computer where the code is running doesn't have a stable internet connection, it might get stuck on step 7 where it's trying to load the image. On the other hand, if the internet connection is stable, the image might load successfully.

  2. Firewall or Network Restrictions: Some computers might have stricter firewall settings or network restrictions that prevent them from accessing certain websites or resources. This could result in the image not being loaded, causing the page to appear stuck.

  3. Browser Compatibility: Different browsers might interpret JavaScript and HTML slightly differently. If the code relies on certain browser-specific behaviors or features, it might work differently or not at all on various browsers.

  4. Cross-Origin Restrictions: If the code is being executed within a different domain or context than the one the resources are hosted on, it might run into cross-origin restrictions that prevent certain actions, such as loading an image from an external domain.

  5. Content Changes: Websites and resources can change over time. If the URL 'https://content.crucial.com/content/dam/crucial/web-ui/scanner/scanner-loading-image.gif' has been modified or the image has been removed, this could affect the behavior of the page.

  6. JavaScript Errors: If there are JavaScript errors in the code or other parts of the page, it could disrupt the normal flow of execution and lead to unexpected behavior.

To troubleshoot the issue, you can try the following steps:

  • Check Network Connection: Ensure that the computer running the code has a stable and active internet connection.

  • Inspect Browser Console: Open the browser's developer console (usually by pressing F12 or right-clicking and selecting "Inspect" or "Inspect Element") and check for any JavaScript errors or warnings that might be logged there.

  • Test on Different Browsers: Try running the code on different browsers to see if the behavior is consistent or if it varies.

  • Check URL Validity: Verify that the URL for the image ('https://content.crucial.com/content/dam/crucial/web-ui/scanner/scanner-loading-image.gif') is accessible and the image is still available at that location.

  • Disable Browser Extensions: Some browser extensions might interfere with the page's functionality. Try disabling any extensions and see if the behavior changes.

If the issue persists and you're unable to identify the exact cause, you might want to reach out to technical support from the relevant parties, such as Crucial.com, for assistance.

This page is in Quirks Mode. Page layout may be impacted. For Standards Mode use “”. sysprofile.htm Content-Security-Policy: The page’s settings blocked the loading of a resource at inline (“script-src-elem”). sysprofile.htm:3:30 Content-Security-Policy: The page’s settings blocked the loading of a resource at inline (“script-src-attr”). Source: javascipt:timedRefresh(6000); sysprofile.htm Content-Security-Policy: The page’s settings blocked the loading of a resource at inline (“script-src-attr”). DocumentFreezer.js:55:10 Content-Security-Policy: The page’s settings blocked the loading of a resource at inline (“script-src-attr”). DocumentFreezer.js:77:16

The messages you're seeing are related to Content Security Policy (CSP) violations and the document mode of the HTML page.

  1. Document Mode Warning: The message "This page is in Quirks Mode. Page layout may be impacted. For Standards Mode use <!DOCTYPE html>." indicates that the HTML page is being rendered in Quirks Mode. Quirks Mode is a compatibility mode used by older browsers to render web pages as if they were intended for older versions of HTML. This mode can result in inconsistent rendering and layout issues. To use Standards Mode, make sure the document type declaration (<!DOCTYPE html>) is added at the beginning of the HTML code.

  2. Content Security Policy (CSP) Warnings: These messages are related to the Content Security Policy (CSP) implemented on the page. CSP is a security feature that helps prevent cross-site scripting (XSS) and other code injection attacks by specifying which sources of content are allowed to be loaded and executed.

    The messages indicate that inline JavaScript code execution is being blocked by the CSP settings. This means that the JavaScript code embedded directly in the HTML, such as the onload='javascipt:timedRefresh(6000);' attribute, is being prevented from running due to the CSP policy.

    The script-src-elem and script-src-attr refer to different aspects of CSP settings related to inline scripts and scripts loaded as attributes.

    To address these CSP issues, you might need to modify the CSP policy to allow the specific inline JavaScript code to run. However, be cautious when adjusting CSP settings, as they are designed to enhance security, and relaxing them might introduce vulnerabilities.

To summarize, you should consider the following steps:

  1. Add a doctype declaration at the beginning of your HTML code to ensure the page renders in Standards Mode: <!DOCTYPE html>.

  2. Review the CSP settings for the page and adjust them if necessary. However, make sure you understand the security implications of modifying CSP settings.

  3. If you have control over the page's source code, consider moving away from using inline JavaScript and use external script files instead. This can help avoid CSP issues and improve maintainability.

  4. If the page behavior is critical, consider reaching out to your web hosting or development team for assistance in properly configuring the CSP policy and addressing the quirks mode issue.
