Hi , I have made a file with almost 10 different ajax calls . And i made it with simple ajax script (just check the browser and call the php and return the response in the div). But i have used smarty (tpl files ) to load inside the div. I am getting lot of errors randomly (no consistency ). Now i am come to the point. ->Is it possible to replace this simple ajax with any other method (like jquery ,etc). ->I have final submit button(If any one script is running then i need to hide the button to stop submit). ->cross browser support ->while ajax request i need to display as loading (something similar to this) to make the customer know whats going on. ------------------- Any body understand what i mean Any help
