getAttribute() inside an attachedListener function() returns 'null' (CKEditor 4.4.8) -

-

in plugin insert input elements of type "button". give elements data attributes. testing purposes called "data-test". further on attach listener recommended in answer. when click button function() called. inside function() need retrieve "data-test" attribute further actions.

but getattribute('data-test') returns null. guess variable "linkelement" not hold customer attributes.

any hints how reference data attributes correctly ?

....

var buttonelement = '<input  type="button"  value="click me"  data-test="test attribute"></input>'; var linkelement = ckeditor.dom.element.createfromhtml(buttonelement, editor.document); editor.insertelement(linkelement);  // attach listener capture clicks editor.editable().attachlistener( linkelement, 'click', function() {                             var attribute = linkelement.getattribute('data-test');                             ...                             console.log('attribute = ',attribute);                 } ....

i answer question myself because problem solved. or better dissapeared. neither can coming nor why gone. bit weird may has been coding problem somewhere in long chain of neverending javascripts. anyway while days ago custom attributes not retrievable, now. code above works perfect. tested firefox, chrome , safari on mac. latest version.

c++ - Delete matches in OpenCV (Keypoints and descriptors) -

i want check scene image against 2 train images. that, detect features , compute descriptors of both training images. before detecting, computing , matching scene image, delete matches of train1 , train2. because these matches won't facilitate matching of scene image train1 , train2. so, match train1 train2 , vector of matches trainidx , queryidx. how can delete these matches in keypoints-vector , descriptor matrix of train1 , train2? best regards, dwi i have done below: std::vector<cv::keypoint> keypoints[2]; cv::mat descriptor[2]; std::vector< cv::dmatch > matches; /* write code generate keypoints, descriptors , matches here... keypoint[0] -> train image 1 keypoints keypoint[1] -> train image 2 keypoints descriptor[0] -> train image 1 descriptors descriptor[1] -> train image 2 descriptors matches -> matched between train image 1 , 2 */ // logic keep unmatched keypoints , corresponding descriptor

i used nvidia sdk bitonic sort , works great me. 32 bits (uint) need ulong keys. have typically 2^14 keys @ time , power of 2. searched on not find kernel designed ulong. i tried modified nvidia sdk bitonic sort using ulong keys not work. kernel not crash after de call clenqueuendrangekernel got error : cl_invalid_command_queue can tell me how modify bitonic sort or radixsort, or can sort ulong keys? i running nvidia quadro 4000 opencl 1.1 cuda 6.5.20 full_profile used original nvidia sdk bitonicsort.cl i used"ulong" keys , value input , ouput instead of "uint" thanks helping i made work-around suit need. used 30 bits of key , 18 high bits of value sorting. changed comparators (2 lines): '#define mask 0xffffc000 // suit need from this: if( (*keya > *keyb) == dir ) this: if(((*keya > *keyb)||((*keya == *keyb)&&((*vala & mask)> (*valb & mask)))) == dir ) it works fine. but, still, it's work-a
