How to Match Element Names with Wildcards Using

Wildcard Element Name Matching with "querySelector()" and "querySelectorAll()": Alternative Solutions to XPath

In JavaScript, the "querySelector()" and "querySelectorAll()" methods allow for efficient element selection within a document. While these methods don't support direct wildcards for element names, there are alternative solutions for partial name matching.

Partial Attribute Matching

Utilizing attribute selectors provides a viable solution. By incorporating wildcards into attribute queries, you can target elements with specific substring matches. For instance:

  • [id^='someId'] matches elements with IDs starting with "someId."
  • [id$='someId'] matches elements with IDs ending with "someId."
  • [id*='someId'] matches elements with IDs containing "someId."

By substituting "id" with "name," this same approach can be applied to match elements based on partial name attributes.

Note: This solution is specifically suitable for matching attributes, not element tag names.

Other Alternatives

If your goal is to match element tag names using wildcards, alternative methods need to be considered, as "querySelector()" does not support this feature directly. Exploring third-party libraries or regular expression-based approaches are potential options.
