Store and inject code to browser pages made super easy.

  • InjectCode
What is InjectCode?
InjectCode is an innovative Chrome extension targeted at developers. It provides an easy way to store and inject JavaScript snippets into browser pages, particularly useful when dealing with sites where code-side access is not available. With InjectCode, developers can manage their scripts, enjoy syntax highlighting, and autosave, with the benefit of local storage across sessions. Scripts can be run either individually or collectively based on their active status, and on a scope of either current or all open tabs. The tool comes with inbuilt jQuery and provides additional functionalities like the function openTab(url) and the XhrMonitor object suited for working with ajax pages.

It is very nice. Please fix the SCOPE because it is not working properly. You can add a feature to set a domain for its scope. GOOD JOB
