javascript - How to find a particular button/element using both the data-* and value attribute -


i have 2 dynamically generated buttons: 

<button type="button" data-btntyp="btnop" data-usrrole="3" data-reqid="24" class="btn btn-primary btn-xs" style="width: 75px" value="start">start</button> <button type="button" data-btntyp="btnop" data-usrrole="3" data-reqid="24" class="btn btn-primary btn-xs" style="width: 75px" disabled="true" value="complete">complete</button>

the 2 buttons have same data-reqid different values. trying find() button data-reqid="24" , value="complete" , enable button. new jquery , have tried this:

$("button[data-reqid='" + reqid+ "'][value=complete]").attr('disabled', 'false');

but that's syntactically not correct , hence doesn't seem work.

couple of things. if want enable button, need set disabled "false". also, need specify actual boolean value disabled attribute. don't supply string value of "true" of "false".

in other words, should be"

.attr('disabled', false);

and not:

.attr('disabled', 'false');

full example:

var reqid = 24;  $('button[data-reqid="' + reqid+ '"][value="complete"]').attr('disabled', false);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>  <button type="button" data-btntyp="btnop" data-usrrole="3" data-reqid="24" class="btn btn-primary btn-xs" style="width: 75px" value="start">start</button>  <button type="button" data-btntyp="btnop" data-usrrole="3" data-reqid="24" class="btn btn-primary btn-xs" style="width: 75px" disabled="true" value="complete">complete</button>

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...
