arrays - Most efficient way to parse a complex string in Javascript -


i'm having trouble parsing string.

newparams=[ "3","2","img1x:51","img1y:111","img1h:209","img1w:330","img1px:231","img1py:291","img1dx:44","img1dy:104","img2x:51","img2y:331","img2h:100","img2w:329","img2px:274","img2py:408","img2dx:44","img2dy:324","txt1x:399","txt1y:119","txt1h:103","txt1w:303","txtbox1x:391","txtbox1y:111","txtbox1h:119","txtbox1w:319","txt1px:679","txt1py:199","txt1dx:392","txt1dy:112","txt2x:399","txt2y:249","txt2h:103","txt2w:303","txtbox2x:391","txtbox2y:241","txtbox2h:119","txtbox2w:319","txt2px:679","txt2py:329","txt2dx:392","txt2dy:242","txt3x:399","txt3y:379","txt3h:44","txt3w:304","txtbox3x:391","txtbox3y:371","txtbox3h:60","txtbox3w:320","txt3px:680","txt3py:409","txt3dx:392","txt3dy:372"];

the string contains height, width, x , y coordinates of both text objects , image objects need position , resize in dom.

the first 2 values in array number of textfields, , number of images (which going use in loops max number of iterations).

i need parse number values, , push them in these individual arrays.

var textxcoords  = new array(); var textycoords  = new array(); var textheight  = new array(); var textwidth  = new array();  var txtboxxcoords  = new array(); var txtboxycoords  = new array(); var txtboxheight  = new array(); var txtboxwidth  = new array();  var textpullxcoords  = new array(); var textpullycoords  = new array(); var textdragxcoords  = new array(); var textdragycoords  = new array();  var imgxcoords  = new array(); var imgycoords  = new array(); var imgheight  = new array(); var imgwidth  = new array();  var imgpullxcoords  = new array(); var imgpullycoords  = new array(); var imgdragxcoords  = new array(); var imgdragycoords  = new array();

for instance in "img1x:51" (image 1, y coord), number 51 pushed imgxcoords array @ position 0.

and in "img2y:111" (image 2, y coord), number 111 pushed imgycoords array @ position 1.

and in "txt2w:303" (textfield 2, width), number 303 pushed txtboxwidth array @ position 1.

if can show me how push img(i)x , img(i)y values arrays (imgxcoords , imgycoords) using loop, can figure out rest there.

i don't know efficient way search looking in string , push proper array.

i tried x coordinates of images, start , end positions way off.

var ix1 = newparams.indexof("img"+(1)+"x"); var ix2 = (ix1 + 7); var res = newparams.substr(ix2,(ix2+2));

if send "res" console.log, get: 1","img1y:111","im result.

when put loop, , sub "1" var i=0, gets more wacky.

here jfiddle of attempt: http://jsfiddle.net/s9rgh/

split friend. see if did here helps: jsfiddle

you can use split segment string individual name/value pairs , put them in array easy access.

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;...

python 3.x - Mapping specific letters onto a list of words -

can please suggest approach write piece of codes automatically maps letter in letter_str onto dic_key (a dict key string type contains dashes match length of words in word_lst)? so, mapping occurs if letter appears in every words in list @ same position no matter how many words in list. if no letter appears @ position words in word list new_dic_key '----'. please see examples below thanks word_lst = ['ague', 'bute', 'byre', 'came', 'case', 'doze'] dic_key = '----' letters_str ='abcdefghijklmnopqrstuvwxyz' new_dic_key = '---e' if word_list = ['bute', 'byre'] new_dic_key = 'b--e' or word_list = ['drek', 'drew', 'dyes'] new_dic_key = 'd-e-' if words in word_list of same length code give want: word_list = ['drek', 'drew', 'dyes'] cols = [] in range(len(word_list[0])): cols.append([]) word in ...
