javascript - Scrolling inner div on key down and up -


I have created an autocomplete container that shows the first four results and the other is hidden and the internal device The element that can be seen while scrolling is the element which holds all the results.

I have implemented the key when pressing up and down keys to easily navigate the results of navigating users, but with the result the internal div is not scrolling.

How can you scroll the element in which overflow-y: hidden and not the window?

In the example, just press any key inside the input box and use your arrow to move down, you will see that div is not scrolling

You can update your script to find the relative position of the selected element and scroll it out: 

  $ ("some input"). ("Keyp", function (a) {$ ("cover"). Show (); if (e.j. == 40) {$ ('. Element: no (last child) .element-hover'). RemoveClass ('element -hover') .next () addClass ('element-hover');} Else if (e.which == 38) {$ ('element: not (: first-child) .element-hover AddClass ('element-hover');} // scroll to element: $ (". Set top (".wrapper_div"). Scrolltop ($ ('. Element-hover: first') .offet () top-$ (".rapper.inner_div"). Height ()); // Then selected Scale from element to element Set the height of Ing}};

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number".

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
