Javascript displaying image -


my overall goal load image given user lattitude , longitude. however, code has error logic somewhere assume (document.write("dog") never displaying screen) have assume going wrong. user being prompted lat , longitude after clicking button afterwards nothing happening. ideas might going on? i'm beginner sure simple. 

<body> <p>click button demonstrate prompt box.</p> <button onclick="myfunction()">try it</button>    <script>         function myfunction() {             var x;             var latittude = prompt("please enter lat");             var longitude = prompt("please enter longitude");             var img = document.createelement('img');             img.src = 'http://maps.googleapis.com/maps/api/streetview?size=400x400&location='+ latittude + ',' + longitude + '&heading=235&sensor=false';             img.height = 200;             img.width = 300;             img.alt = alt;             document.write(img.src);             document.write("dog");             document.getelementbyid('body').appendchild(img);         } </script>  </body>

img.alt = alt; have not defined variable named alt.

document.getelementbyid('body') there no id value of 'body', reference use document.body.appendchild(img);.

also unless messing around practice, take at: why document.write considered “bad practice”?.

for future reference if use developer tools in browser (f12) script errors printed out in console.

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;...
