You can efficiently search across all loaded source files (including HTML, CSS, and JavaScript) within Microsoft Edge DevTools by utilizing the dedicated Search panel, accessible directly from the DevTools toolbar. This feature allows you to quickly locate specific text strings, code snippets, or regular expressions throughout your entire loaded application.
Accessing the Search Panel in Edge DevTools
To begin searching through all files in Edge DevTools, follow these straightforward steps:
- Open DevTools: First, navigate to the desired web page where you wish to perform the search. Then, right-click anywhere on the page and select Inspect from the context menu that appears. This action will open the DevTools window.
- Locate 'More Tools': With DevTools open, look for the 'More Tools' button in the main DevTools toolbar. This button is often represented by a
+icon or three dots (...) and is typically situated towards the right end of the toolbar. - Select 'Search': Click the 'More Tools' button. From the dropdown list that appears, select Search. This action will open the dedicated Search panel, usually at the bottom of the DevTools window.
Understanding the DevTools Search Panel
Once the Search panel is open, you can begin your comprehensive search across all files loaded by the current web page. This includes your webpage's HTML, linked CSS stylesheets, JavaScript files, and even content from network responses.
Performing a Search Query
- Enter Search Term: In the input box provided within the Search panel, type the text string or pattern you wish to find.
- Refine Your Search: To make your search more precise, consider using the following options, typically located next to the search input field:
- Match Case (Aa): Toggle this option to perform a case-sensitive search. If enabled, "example" will not match "Example".
- Regular expression (.*): Enable this option to use regular expressions for advanced pattern matching. For instance,
^functionwould find all lines starting with "function".
- Initiate Search: Press
Enteror click the search button (often a magnifying glass icon) to execute your query.
Navigating Search Results
The Search panel will display a list of all occurrences matching your query. Results are grouped by file and show the line number along with a snippet of the code where the match was found.
- Click to Navigate: Clicking on any search result will automatically open the corresponding file in the Sources panel, highlighting the exact line where the match was found. This allows for immediate inspection and editing.
Why Use the DevTools Search Feature?
The global search functionality in Edge DevTools is invaluable for various development and debugging scenarios:
- Debugging: Quickly locate specific function calls, variable definitions, or error messages across your entire codebase.
- Auditing and Refactoring: Find all instances of a specific CSS class, HTML ID, or deprecated JavaScript function to facilitate systematic updates or removals.
- Text Discovery: Identify specific text content within the rendered page's source, useful for content verification or tracking marketing tags.
- Security Analysis: Search for sensitive data patterns or known vulnerabilities within loaded scripts.
Practical Tips for Effective Searching
- Use Regular Expressions: For complex patterns, such as finding all
divelements with adata-attribute, regular expressions (<div\s+data-.*?>) are incredibly powerful. - Leverage Search History: The DevTools Search panel typically keeps a history of your previous searches, making it easy to revisit frequently used queries.
- Combine with Other Tools: Once you find a specific line of code, you can set breakpoints in the Sources panel or inspect elements in the Elements panel for deeper analysis.
