jquery not working

My jQuery form validation not working in textastic.  It works on a PC but when I try to run the program on my iPad through textastic app, these functionalities do not work.  All my form validation does not exist at all in this app.  I'm using HTML5, javascript, jquery.  This is a great app but is useless without being to test out my form validations on the go.  Any help would be greatly appreciated.
