I want to use Router.go('...') function to navigate via javascript after e.g. submitting form. Is it possible to do so without refreshing the whole site ? Refresh wouldn't be such a problem, problem is that refresh forces to quit all alerts, so e.g. when user submits form and everything went well, he will get alert and then I want to move him onto another site (with Router.go('...')), but after using this function site refreshes and alert quits. For alerts I'm using sAlert package.
There is an onClose callback event in the s-alert package you can use: https://github.com/juliancwirko/meteor-s-alert#callback-onclose
Just pass a function that has your Router.go into that property of the alert.
