jquery - Get substring between 2 certain characters -

-

for example have string:

via_route_1;via_route_2;via_route_4;via_route_7;

and supply function number (eg. 4), how can substring ;via_route_4 ?

my aim delete substring, depending on number supply.

i know how index of 4, example, how go backwards until find first ; , take whole substring thing?

what that? using no custom functions manipulating string.

/* string */ var s = "via_route_1;via_route_2;via_route_4;via_route_7;";  /* index of 4 */ var i1 = s.indexof("4");  /* substring first character 4 (including number) */ var sub1 = s.substring(1, i1 + 1);  /* last index of ; in substring */ var i2 = sub1.lastindexof(";");  /* new substring starting ; */ var sub2 = sub1.substring(i2, sub1.length); console.log(sub2);

logs ;via_route_4.

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
