为什么带有“_blank”的AJAX响应适用于第一个函数，而不适用于第二个函数？

I have a jsp where there are two radio buttons and based on the button clicked I call corresponding function. Both the functions have ajax call and the success response opens the new url in new tab. The first function does it perfectly , but second function doesn't work properly.I have a jsp where there are two radio buttons
