javascript - how to stop a fixed input at the top of a page from making the ipad browser scroll up on focus -

-

i have responsive site top navigation fixed scroll down age header stay @ top edge of browser. in header search input. on iphones , ipads, when user taps in field page scroll top.

i want stop because user decides not search , taps out of search field, should bee left off versus @ top of page.

i have found articles using overflows on scrollable divs, not case plain page. have anchor book marks allows user go sections of page, , lots of home page content. want user able drag way down page, or click on anchor. have ability click search , not have page zip top.

how go javascript have tried preventdefault on focus of field no luck.

any appreciated.

thanks

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
