i have many div s contain links. want check whether or not have link. attempt: var container = $(this).closest('.content').find('.text'); //check if text contains tags if(container+':has(a)'){ alert('contain link'); } else{ alert('no link found'); //alert "contain link" if no link found. } by doing container.html() can see exact content of container including anchor tags, code above cannot find anchor tag. could tell me doing wrong? change this: if(container.find("a").length){ ... container jquery object , .find() function of object finds elements within it. length greater 0 mean finds anchor tag , evaluate true. edit: also, explain why example isn't working. when container+':has(a)' , doing string concatenation runs tostring() on object (converting "[object object]"). end string "[object object]:has(a)" evaluate true.

i'm new python , i'm not extremely familiar syntax , way things work exactly. it's possible i'm misunderstanding, can tell code line: largeboard = [[board() in range(3)] j in range(3)] is creating 9 references same board object, rather 9 different board objects. how create 9 different board objects instead? when run: largeboard = [[board() in range(3)] j in range(3)] x_or_o = 'x' largeboard[1][0].board[0][0] = 'g' # each board has board inside list in range(3): j in range(3): k in range(3): l in range(3): print largeboard[i][j].board[k][l] i multiple 'g' made me think references same object. you have reversed: are creating 9 independent board instances there. if had like largeboard = [[board()] * 3] * 3 then have single instance. root of common mistake many python newcomers make. [x in range(3)] evaluates x once each i (3 times here) whereas [x] * 3 evalua

i have shop page uses javascript cookie store contents of visitor's shopping cart. the cookie stored so: document.cookie=products[x].id + "=" + products[x].qty; and values stored correctly product code , quantity. name value -----------|-------- product1 | 0 product2 | 1 product3 | 2 however, once visitor has checked out , completed shopping flow, there confirmation page resets values of cart: for (x in products) document.cookie=products[x].id + "=" + 0; the values in cookie 0 expected. problem occurs when navigating shop page cookie has inital values , cart not empty. what going wrong? i guess not overwriting original cookie creating new one. have in exact same domain (www.greener.xyz / shop.greener.xyz). must have same protocol (http / https).

i'm looking create non-type templated class member variables depend on non-type parameter (specifically, fixed-dimension eigen matrices, problem present int well). make things clearer typedef'ed member types, worked great until wanted member function return typedef @ point started getting following error: myclass.cpp:10: error: expected constructor, destructor, or type conversion before ‘myclass’ i understand, conceptually @ least, has fact typedef depends on template , result c++ confused. problem i'm more confused, i've tried naive insertions of typename , didn't fix anything. a minimum working example. header: template <int i> class myclass { public: typedef int myvector_t; myclass(); myvector_t myfunc(); }; source code: #include <myclass.hpp> template <int i> myclass<i>::myclass() { //blah } template <int i> myclass<i>::myvector_t myclass<i>::myfunc() //<----- line 10

how can concat 2 fields , text in between? i've tried of following , nothing has worked... ([fldcode1] || ':' ||[fldcode2]) method ([fldcode1] + ':' + [fldcode2]) method ([fldcode1] & ':' & [fldcode2]) method *** & cannot used varchar this should work select [fldcode1] + ':' + [fldcode2] tab or if columns numeric select cast([fldcode1] varchar(100)) + ':' + cast([fldcode2] varchar(100)) tab

i doing java code fetching userstories given project. queryrequest hrrequest = new queryrequest("hierarchicalrequirement"); hrrequest.setfetch(new fetch("name","children","release")); hrrequest.setworkspace(wsref); hrrequest.setproject(prjref); the above code give me userstories tied iterations (i.e., if iteration blank - not fetch userstory) but, need userstories fetched available under project/subproject pls help thanks vg you may set project scope of request: storyrequest.setproject(projectref); as long prior projectref specified: string projectref = "/project/2222"; here code prints out story count in project: public class areststories { public static void main(string[] args) throws urisyntaxexception, ioexception { string host = "https://rally1.rallydev.com"; string username = "apiuser@company.com"; string password = "se

here code involving akka: def receive = { case idlist: list[actorref] => idlist.foreach(x => x ! msg) } sbt complains that: non-variable type argument akka.actor.actorref in type pattern list[akka.actor.actorref] unchecked since eliminated erasure [warn] case idlist: list[actorref] => idlist.foreach(x => x ! msg) how rid of this? at runtime list[whatever] equivalent list[any] , actor can figure out received list not it's list of actorref s. jvm thing , not scala's or akka's fault. you have 2 choices: 1) ignore replacing actorref _ case idlist: list[_] => ... 2) wrap datastructure (recommended) case class ids(idlist: list[actorref]) the second choice let's check against ids without having check parametric type of list. def receive = { case ids(idlist) => idlist.foreach(x => x ! msg) }

i have piping scheme using subprocess 1 process p2 takes output of process p1 input: p1 = subprocess.popen("ls -al", shell=true, stdout=subprocess.pipe, stderr=subprocess.pipe) p2 = subprocess.popen("grep mytext - ", shell=true, stdin=p1.stdout, stdout=subprocess.pipe) result = p2.communicate() p1 or p2 fail various reasons, wrong inputs or malformed commands. this code works fine when p1 not fail. how can check whether p1 or p2 failed? example: # p1 fail since notafile not exist p1 = subprocess.popen("ls notafile", shell=true, stdout=subprocess.pipe, stderr=subprocess.pipe) p2 = subprocess.popen("grep mytext - ", shell=true, stdin=p1.stdout, stdout=subprocess.pipe) result = p2.communicate() i can check p2.returncode , see it's not 0 , mean p2 failed or p1 failed. how can check whether p1 failed or p2 failed in cases pipe goes wrong? i don't see how can use p1.returncode ideal , obvious solution. ex: p1 = su

i have 2 list<string> l1 = {"one", "two","three","four"} l2 = {"one", "three"} i want know if of l2 inside l1 bool? var allin = !l2.except(l1).any();

this problem has bugged me while. i have jpeg file 34.6 kilobytes. let's call image a. using ruby, when copy each line of image a newly created file, called image b, copied exactly. same size image , accessible. here code used: image_a = file.open('image_a.jpg', 'r') image_b = file.open('image_b.jpg', 'w+') image_a.each_line |l| image_b.write(l) end image_a.close image_b.close this code generates perfect copy of image_a image_b. when try copy image image b, byte byte, copies file size 88.9 kilobytes rather 34.6 kilobytes. can't access image b. mac system alerted me may damaged or using file format isn't recognized. the related code: //same before image_a.each_byte |b| image_b.write(b) end //same before why image b, when copied byte byte, larger image a? why damaged in way, shape, or form? why image same size b, when copied line line, , accessible? my guess problem encoding issue. if so, why encoding format matter w

in code below class { public void v(int... vals) { system.out.println("super"); } } class b extends { @override public void v(int[] vals) { system.out.println("sub"); } } then can call new b().v(1, 2, 3);//print sub rather super ridiculous does work well . if change b class b { public void v(int[] vals) { system.out.println("not extending a"); } } the call new b().v(1, 2, 3); invalid. have call new b().v(new int[]{1, 2, 3}); , why? under jdk 1.7, neither of examples compiles, , don't believe should. it's easy see why second version doesn't - when b doesn't extend a , there's no indication of varargs @ all, there's no reason why compiler should possibly convert argument list of 3 int arguments single int[] . more interesting situation b does extend a . the compiler finds signature of v(int[] vals) doesn't use varargs. there's nothing in sp
