javascript - Issue on Passing Dom val() and html() to Polygon Options in Drawing -


i trying pass values dom .val() , .html() this:

$("#drawpolygon").on("click",function(){     var polyname = $("#polydatasetname").val();     var polycolor = $("#polyfillcolor").val();     var polytranc = ($("#polytrancparency").html()).slice(2);     var polybordercolor = $("#polybordercolor").val();     var polybordersize = $("#polybordersize").html();     var polybordertranc = ($("#polybordertransparency").html()).slice(2);  });

i tried alert result correct when pass them polygonoptions options like:

 polygonoptions: {           fillcolor: polycolor,           fillopacity: (polyfillcolor/100),           strokecolor: polybordercolor,           strokeweight:polybordersize,           clickable: false,           editable: true,           zindex: 1    }

i getting following error message

enter image description here

can please let me know why happening , how can solve it? here code have drawing manager:

<script> var map; var drawingmanager $(document).ready(function () {     var latlng = new google.maps.latlng(49.241943, -122.889318);     var myoptions = {         zoom: 12,         center: latlng,         disabledefaultui: true,         maptypeid: google.maps.maptypeid.roadmap     };   map = new google.maps.map(document.getelementbyid("map_canvas"), myoptions);      $("#drawpolygon").on("click",function(){         var polyname = $("#polydatasetname").val();         var polycolor = $("#polyfillcolor").val();         var polytranc = ($("#polytrancparency").html()).slice(2);         var polybordercolor = $("#polybordercolor").val();         var polybordersize = $("#polybordersize").html();         var polybordertranc = ($("#polybordertransparency").html()).slice(2);      });      drawingmanager = new google.maps.drawing.drawingmanager({         drawingmode: google.maps.drawing.overlaytype.marker,         drawingcontrol: true,         drawingcontroloptions: {             position: google.maps.controlposition.top_center,             drawingmodes: [             google.maps.drawing.overlaytype.marker,             google.maps.drawing.overlaytype.circle,             google.maps.drawing.overlaytype.polygon,             google.maps.drawing.overlaytype.polyline,             google.maps.drawing.overlaytype.rectangle]         },       polygonoptions: {       fillcolor: polycolor,       fillopacity: (polyfillcolor/100),       strokecolor: polybordercolor,       strokeweight:polybordersize,       clickable: false,       editable: true,       zindex: 1     }  });  </script>

the problem define polycolor(and other variables) locally inside of anonymous function executed when click on specified div , function executed, variables dicarded.

meaning when creating object polygonoptions, variables not defined(they not exist anymore).

to solve this, define variables inside of document.ready function:

$(document).ready(function() {     var polyname;     var polycolor;     var polytranc;     var polybordercolor;     var polybordersize;     var polybordertranc;     ...  });

then on click event assign values these variables:

$("#drawpolygon").on("click",function() {     polyname = $("#polydatasetname").val();     polycolor = $("#polyfillcolor").val();     polytranc = ($("#polytrancparency").html()).slice(2);     polybordercolor = $("#polybordercolor").val();     polybordersize = $("#polybordersize").html();     polybordertranc = ($("#polybordertransparency").html()).slice(2); }

and should work expected now.
