jquery mobile - Validate elements outside a form -


i have elements (input, textarea, controlgroup) , submit button outside of form element...

can validate elements (client-side)? instance, check if required , show message error if empty. can use jquery validation plugin that? how?

here sample of code until now:

<div id="formcontainer">      <div data-role="fieldcontain">         <fieldset data-role="controlgroup">             <legend>user:</legend>             <div id="userscontainer">                <input type="radio" name="radio-choice-1" id="radio-choice-1" value="1" />                <label for="radio-choice-1">user1</label>                <input type="radio" name="radio-choice-1" id="radio-choice-2" value="2" />                <label for="radio-choice-2">user2</label>             </div>         </fieldset>     </div>      <div data-role="fieldcontain" class="ui-hide-label">         <label for="subjectmessage">subject:</label>         <input type="text" name="subjectmessage" id="subjectmessage" value="" placeholder="subject" />     </div>      <div data-role="fieldcontain" class="ui-hide-label">         <label for="bodymessage">body:</label>         <textarea name="bodymessage" id="bodymessage" placeholder="body" rows="8"></textarea>     </div>      <input id="sendmessagebtn" type="submit" value="send" /> </div>  <script type="text/javascript">      $(document).one("pageinit", function () {          $("#sendmessagebtn").on("click", function () {              var userid= $('#formcontainer').find("#userscontainer :radio:checked").val();             var subject = $('#formcontainer').find("#subjectmessage").val();             var body = $('#formcontainer').find("#bodymessage").val();              //send data server...         });      });  </script>

yes, there 2 approaches.

  1. you don't use server side helpers generate markup , have hardcoded entire markup (as shown in question). bad if decide go approach have add corresponding data-* attributes input fields unobtrusive validation framework using. it's possible use unobtrusive validation framework outside asp.net mvc, example in php application assuming input fields contain data-* attributes. said in previous sentece: outside asp.net mvc application begs question: why using asp.net mvc in case if not take advantage of it?. recommend scraping approach , @ second possibility.

  2. you use server side helpers generate input fields such html.editorfor, html.textareafor, html.dropdownlistfor, ... helpers take care of generating proper data-* attributes under 1 condition: elements inside form. not case, cheat adding following line top of view trick them thinking inside form:

    @{     this.viewcontext.formcontext = new formcontext(); }

keyboard - C++ GetAsyncKeyState alternative -

i using windows.h library's getasynckeystate function define key pushed on keyboard . here program returns int value of pushed key example. #include <iostream> #include <windows.h> using namespace std; int main (){ char i; for(i=8;i<190;i++){ if(getasynckeystate(i)== -32767){ cout<<int (i)<<endl; } } return 0; } but trying make opengl simple game , function appeared slow . there function not need cycle 180 times , if statement . thanks you're trying make opengl game, you're going use glfw. if that's case can away using glfwgetkey() such: if (glfwgetkey(glfw_key_up) == glfw_press) {...} if (glfwgetkey(glfw_key_down) == glfw_press) {...} that method nicely explained in tutorial 6 opengl-tutorial.org . should start first tutorial of beginners tutorials , later intermediate tutorials . if you're going make win32 window can listen wm_keydown or wm_keyup messages , virtua
