save - jVectorMap - How to get value from markers and store it to a variable -


i managed create map using jvectormap markers in map.

now, how can value marker when user clicks on it?

jsfiddle link: http://jsfiddle.net/fqqgs/78/

     $(function(){         $('#map').vectormap({         map: 'us_aea_en',         zoomonscroll: false,         hoveropacity: 0.7,         markerstyle: {           initial: {             fill: '#f8e23b',             stroke: '#383f47'           }         },  markers: [      {latlng: [41.50, -87.37], name: 'chicago', newvalue: '300'},           {latlng: [32.46, -96.46], name: 'dallas', newvalue: '301'},           {latlng: [36.10, -115.12], name: 'las vegas', newvalue: '302'},           {latlng: [34.3, -118.15], name: 'los angeles', newvalue: '303'},           {latlng: [40.43, -74.00], name: 'new york city', newvalue: '304'}         ],             onmarkerclick: function(event, index){   var = 2; var b=2+newval; //need value each markers , save value newval alert(b);   }         });     });

assign markers array variable inside of anonymous function can reference in both assignment of map markers , inside onmarkerclick closure.

   $(function () {        //assign markers variable        var mapmarkers = [               {latlng: [41.50, -87.37], name: 'chicago', newvalue: '300'},                {latlng: [32.46, -96.46], name: 'dallas', newvalue: '301'},                {latlng: [36.10, -115.12], name: 'las vegas', newvalue: '302'},                {latlng: [34.3, -118.15], name: 'los angeles', newvalue: '303'},                {latlng: [40.43, -74.00], name: 'new york city', newvalue: '304'}         ];         $('#map').vectormap({            map: 'us_aea_en',            zoomonscroll: false,            hoveropacity: 0.7,            markerstyle: {                initial: {                    fill: '#f8e23b',                    stroke: '#383f47'                }            },            markers: mapmarkers,            onmarkerclick: function (event, index) {                var = 2;                //retrieve marker index , parse string value integer                var newval = parseint(mapmarkers[index].newvalue);                var b = 2 + newval; //need value each markers , save value newval                alert(b);            }        });    });

opencv - DataType<cv::detail::deriv_type>::depth what is it used for -

i wondering why line used in lucas kanade tracker in opencv: datatype<cv::detail::deriv_type>::depth can explain me? in opencv, depth of mat refers type of data contained in mat 's data buffer. represented integer values correspond given data type. these integers commonly abstracted appropriate macro definition (e.g. uchar data represented macro cv_8u ). cv::datatype type-traits class provides method obtain corresponding integer value without having memorize macro means data type. there few cases user code needs use datatype::depth . more common datatype::type . a simple example shows 1 possible use of datatype::depth : cv::mat uchar_data = cv::mat::ones(3, 3, cv_8uc1); cv::mat float_data; uchar_data.convertto(float_data, cv::datatype<float>::depth); // ^^ equivalently replaced // cv_32f macro float_data.at<float>(0,1) += 0.5f; std::cout << float_data << std::endl;...
