There is a non-existent variable referenced somewhere. This variable needs to be declared, or you need to make sure it is available in your current script or scope otherwise , it will endup throwing this 'x' is not defined error . This usually indicates that your library is not loaded and JavaScript does not recognize the 'x'.

To solve this error: Load your library at the beginning of all your scripts.

There can be multiple other reasons for this issue:

• Added JavaScript library after the script were you see that error
• Conflict with Other JavaScript Libraries
• Path to JavaScript library you included is not correct
• The jQuery library file is corrupted
• May be a chance where you are working offline
