javascript - Angular JS ternary operator inside div tag -


am using div condition shown below 

<div data-index="5" class="col-xs-12 col-sm-4 col-md-3 col-lg-2 tiles ${ {{myvariable.data}} ? 'hidden-lg hidden-md hidden-xs hidden-sm':''}" data-myapp-detail="somexyz">

where {{myvariable.data}} giving problem when becomes "false". there angular js condition can initiate variable based on {{myvariable.data}} , use variable in div tag ternary condition.

where if keep boolean value false directly instead of {{myvariable.data}} works expected.

<div data-index="5" class="col-xs-12 col-sm-4 col-md-3 col-lg-2 tiles ${ false ? 'hidden-lg hidden-md hidden-xs hidden-sm':''}" data-myapp-detail="somexyz">

for angular2

<div data-index="5"    class="col-xs-12 col-sm-4 col-md-3 col-lg-2 tiles"   [ngclass]="myvariable.data ? 'hidden-lg hidden-md hidden-xs hidden-sm':''"    data-myapp-detail="somexyz">

or

<div data-index="5"    class="col-xs-12 col-sm-4 col-md-3 col-lg-2 tiles"   [ngclass]="myvariable.data ? ['hidden-lg', 'hidden-md', 'hidden-xs', 'hidden-sm']:''"    data-myapp-detail="somexyz">

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...
