javascript - jQuery/CSS: Changing the height and width attributes of an image when clicked -


i'm working on simple gallery built html, css, , jquery. when user clicks on image, larger version of image should pop in frame overlay behind it. have no problems horizontally-oriented images, vertically-oriented images, larger image comes out distorted.

you can view working sample on codepen: http://codepen.io/anfperez/pen/axzgrv

i try change the attributes of image saving height of image in variable , changing attribute using jquery, doesn't seem working.

how can access height , width of larger image url , put frame? trying following code, did not work.

var height_large = $(this).attr('height')  var width_large = $(this).attr('width')  $('#frame img').attr('height', height_large) $('#frame img').attr('width', width_large)

for reference, here actual url of photo i'm trying pull down: https://farm8.staticflickr.com/7072/7274940170_c166072ddf_c.jpg

changing height auto #frame img worked me. displays larger image fixed width , accomodates height accordingly. renders proportionally correct. you'll want make sure images @ least wide fixed width start avoid upscaling.

#frame img {   display: none;    position: fixed;   background-color: white;   width: 700px;   height: auto;   margin-left: -350px;   left: 50%; }

c# - Check Keyboard Input Winforms -

i wondering if instead of doing this protected override void onkeydown(keyeventargs e) { if (e.keycode == keys.a) console.writeline("the key down."); } i set bool method , this: if(keydown(keys.a)) // whatever here i've been sitting here ages trying figure out how it. can't wrap head around it. in case wondering, plan call bool inside different method, check input. since want perform action after pressing key, using keydown event enough. but in cases suppose want check if specific key down in middle of process, can use getkeystate method way: [dllimport("user32.dll", charset = charset.auto, exactspelling = true)] public static extern short getkeystate(int keycode); public const int key_pressed = 0x8000; public static bool iskeydown(keys key) { return convert.toboolean(getkeystate((int)key) & key_pressed); } you should know, each time check key state using example iskeydown(keys.a) method returns true if ke...
