问题 I'm just learning Rails and would appreciate any help. I've looked at probably 10 tutorials for :remote => true on form_for and they all seem to copy each other (equally confusing).

For example in this javascript function the .load() directive works the first time, but after that it keeps 'fetching' the same page from cache. function placeBet(user, bet) { var ajax_data = { status:false, message: '' } $.ajax({ url:'/place_bet/' + user + '/?ajax=&bet=' + bet, type:"POST", dataType:
