i dont know why this error occuring

registerNamespace and registerClass functions are part of the MS AJAX framework and have nothing to do with jquery. So the question is which one of the two frameworks you would like to use MS AJAX or jquery? So if you want to use those functions make sure you have included the proper files: MicrosoftAjax.js, MicrosoftMvcAjax.js.
