javascript - Dynamically change Dojo multiselect values -

-

i want add multiselect widget form set values. , when user clicks on button, values inside multiselect widget changes.

when form crashes.

this sample code issue:

 <script type="text/javascript" >     function test(){          var msobj = dijit.byid('ms1');         msobj.set('label', ['val1', 'val2']);      }     </script>  </head> <body class="claro">  <h2>multiselect test</h2> <h3>click on test button see new data loaded in multiselect widget</h3>     <div data-dojo-type="dijit/form/form" enctype="multipart/form-data"         action="" method="post">         <div data-dojo-type="dojox/layout/tablecontainer"             data-dojo-props="cols:1">              <select id="ms1" data-dojo-type="dijit/form/multiselect"                 title="multiselect123:" name="multi_select">                 <option value="english 123">english 123</option>                 <option value="1234.56">1234.56</option>             </select>            </div>     <br>     <button onclick="test()">test</button>  </body>

the reason crash because on clicking button form gets submitted.
avoid submitting form need return false value in button click function. i.e

<button onclick="test(); return false;">test</button>

also multiselect dojo widget not associated data store/object. per documentation wrapper on select html element.
result need use basic html/js code add , remove options widget.

check jsfiddle working example.

i've been working on making 2d map editor past 2 weeks or so, , i've run strange problem. trying optimize code, example, making functions should've been functions begin with, did made cpu usage go through roof. i've tried commenting out different sections of code thought culprits (scrolling, rendering, other calculations) no avail. think issue might trying call things within different functions, sake of making modular possible, i'd functionality. the other major change i've made since file i'm comparing i've ported variables external cpp file, since having variables global makes lot easier use within different functions. simple issue, can't life of me understand why happens. with original code, around 2-3% cpu usage. new code, around 20-35%, but, if move mouse around, it'll drop around 6-8%. tl;dr: after trying optimize code using functions, i've somehow killed performance, , found strange quirk moving mouse reduces cpu usage.. /...
