Debugging method and device for scripting language application and terminal

The embodiment of the invention discloses a script language application debugging method and device and a terminal, and the method is implemented on the terminal and comprises the steps: carrying outthe static analysis of a to-be-debugged script language application; wherein the scripting language application comprises a scripting language file, and the scripting language file comprises a scripting statement. According to an analysis result, taking the script statement as a debugging unit, and carrying out debuggeability processing on the script language file. And receiving a debugging instruction of the debugging server, and debugging the script language application according to the debugging instruction. Therefore, the script language file is debugged by taking the script statement as the debugging unit, the script language application on the terminal is debugged through the debugging server, a debugging port provided by a script language engine kernel is not required to be used, and the script language app
