What does console.log(data) return ?

Remove dataType: "json", temporarily and check the response.

Thanks astroanu, but I've never used console.log(data) before. How do you use it?

I looked at my storage/logs files and could not see any errors there. I tried removing dataType: "json" but that did not make a difference. My javascript debugger does not show any errors either. My alert returns "undefined"

Am I missing something?

$.post( "path/to/my/controller", function(data) {
    console.log(data);
});

but i think you error is "http://laravel.io/forum/11-14-2014-laravel-5-cant-post"

@poem is that the good old missing csrf token error ?

@djtechonline data['key1'] is undefined because data does not have a key by the name key1. console.log(data); should show what is being returned from the controller on your browser console. (ctrl + shift + j) You need to learn a bit about basic js debugging. :)

success: function(response) {
    alert(response.data.data.key1);
}

I would say it's

success: function(data) {
    alert(data.data.key1); // or data.data['key1'] (?)
}
