Click submit two methods after all want to jump to the background, I want to execute a function first, and then execute 2 function, but this way, he has always been two functions to perform together, 1 function and content is more, the execution time is slower than the 2 function, cause I have been for less than 1 2 function function value of the cache, how should I do to make a function to perform, perform again after the completion of two function?
