javascript - Cannot display another map on map click listener event -


i trying create page loads small google map , working fine. want add map event click shows bigger div displaying google map same lng , lat. div shown google logo , beige background color , there no map , can't figure out problem. working on visual studio 2012 , google map shown using javascript.

below code:

  var latlng;          function initialize(lng, lat) {              var myoptions = {                zoom: 17,                center: latlng,                maptypeid: google.maps.maptypeid.roadmap             };              var map = new google.maps.map(             document.getelementbyid("map_canvas"),             myoptions);              var marker = new google.maps.marker({                position: latlng,                map: map,                icon: "/images/marker.png",                title: "this place."             });              var contentstring = 'hello <strong>world</strong>!';             var infowindow = new google.maps.infowindow({                content: contentstring              });              google.maps.event.addlistener(marker, 'click', function () {                infowindow.open(map, marker);             });              document.getelementbyid("map_canvas").style.visibility = 'visible';              map.addlistener('click', function (e) {              var myoptions2 = {                zoom: 17,                center: latlng,                maptypeid: google.maps.maptypeid.roadmap             };              var map2 = new google.maps.map(               document.getelementbyid("modal-body"),               myoptions2);              var marker2 = new google.maps.marker({                position: latlng,                map: map2,                icon: "/images/marker.png",                title: "this place."             });              var contentstring2 = 'hello <strong>world</strong>!';             var infowindow2 = new google.maps.infowindow({                content: contentstring2             });              google.maps.event.addlistener(marker2, 'click', function () {                infowindow2.open(map2, marker2);             });             document.getelementbyid("mymodal").style.display = "block";                });        }

those divs displaying maps:

 <div id="map_canvas" class="mapdiv" style="visibility:hidden" > </div>     <div id="mymodal" class="modal" style="display: none">       <div class="modal-content">         <span onclick="closemydiv();" id="closespan" class="close">×</span>         <br /><br />         <div id="modal-body"  class="modal-body">            hello world !         </div>       </div>     </div>

i repeat: modal-body changes when click on map-canvas (by adding google logo , changing background color), not displaying map, , tried fill map in div before click event still have same problem.

any hints?

note: if comment concerning map-canvas , i show mymodal div @ onload event, map displayed properly!

1.make sure modal-body have width , height set in css.

2.if div containing map, or it's parent, or it's parent's parent (any predecessor) has display:none set @ point, map view won't initialise , see gray map. noticed show modal after map initialised. map appear properly, either run code 

document.getelementbyid("mymodal").style.display = "block";

before map2 initialisation, or trigger resize event on map after visibility change, reinitialise map view:

google.maps.event.trigger(map2,'resize');

probably not relevant case, need trigger resize event on map if map containing's div dimensions change.

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...
