This paper systematically analyzes the issue where some JavaScript files become invisible in the Sources panel of Chrome Developer Tools. It begins by describing the typical symptoms: in Chrome version 44.0.2403.130, certain JavaScript files loaded via <script> tags fail to display in the Developer Tools Sources menu, despite successful network requests and normal application functionality. The paper then explores potential causes, including Developer Tools cache issues, corrupted user profiles, and the peculiarities of dynamically loaded scripts. Based on best practices from the Stack Overflow community, it emphasizes the solution of reinstalling Chrome and clearing user profile data, which has been validated in multiple cases. Additionally, supplementary techniques such as refreshing the Network panel, restoring default Developer Tools settings, and using debugger statements to force script display are discussed. Finally, preventive measures and debugging strategies are provided to help developers better utilize Chrome Developer Tools for JavaScript debugging.
