javascript - preventDefault( ) on appended html does not work. why? -

the title self explanatory. i'm appending html document in ajax call , prevent default event when click in <a> tag generated function. here's code: $.ajax({ type: 'get', url: "/api/search/info/" +id, accepts: 'application/json' }).then(function(data, status, xhr) { $(".book-results #results").append("<a class='bookitem' href='b"+data.value+"'>add book</a>"); }, showerr); inside same javascript file (but not within ajax function ), have listener: $(".bookitem").click(function(event) { event.preventdefault(); console.log("hello"); }); when trigger ajax event, .book-results #results gets populated, when click <a> tag default event gets triggered. there way make listener work? if so, how? you can't apply event listener before element trying attach listener exists. $(".bookitem").click(function(event) {...}); bind elements c

ios - How to deleteAllObjects from NSSet -

i have method here counts number of annotations on map view. however, every time method called, anncount keeps on incrementing. example, there 5 annotations on map - first time method called returns 5 expected. second time it's called returns 11, 16, 21, 26 , on.. mkmaprect visiblemaprect = mymapview.visiblemaprect; nsset *visibleannotations = [mymapview annotationsinmaprect:visiblemaprect]; anncount = [visibleannotations count]; nslog(@"%u", anncount); return anncount; i thinking if clear objects nsset work properly. however, nsset won't recognise deleteallobjects. have tried nsmutableset doesn't work "annotationsinmaprect:visiblemaprect". cheers. your problem not nsset returned. problem annotationsinmaprect: returning more objects expected. leads me believe add more , more annotations map (perhaps mistake). nsset immutable collection, cannot add or remove objects instance. more, when visibleannotations released, releases object

c# - If network connection is lost while inserting large amount of data, what will happen? -

i using asp.net c# , sql server. inserting 10000 records sequentially. assume after inserting 6000 records, network connection lost. @ time happen? the 6000 records inserted or not? if 6000 records inserted - remaining 4000 records, , how identify how many records inserted , how reverse 6000 records? is there other option rectify problem? if problem occurred need to solve it? there should no duplicate data in end. it depends consider inserting. 10.000 insert statements, no transaction: nothing rolled back. 10k insert statements in transaction - rollback of operations. best way plan that: use sqlbulkcopy temporary table, isnert there final table (sqlbulkcopy has serious issues concurrent table access bypass this). use merge move final table. plan rerunning insert - mergfe makes sure of (no cleanup needed).

i resolve problem don't have solution of kindly ask if can confirm if solution correct or not int h=1; int cont = 0; (j = 2^n; j>1; j = j/2) { h = h * 2; (i =1; < j; = i*2) (k=2; k<h; k++) cont ++; } i must find complexity of portion of code in bigtheta. so, analyze third cycle grow in way k -> linear until = h (h grow 2^w) - complexity log n. about second, first cycles' limit 0 think complexity log n. about first 2^n = 2^n-1 complexity n the total complexity n * log n you can proceed formally, step step, using sigma notation (i skipped steps, feel free ask more details if necessary):

php - HABTM SaveAssociated is performing a SELECT instead UPDATE in CakePHP -

C# convert to date - No implicit conversion between 'System.DateTime' and '<null>' -

this question has answer here: nullable types , ternary operator: why `? 10 : null` forbidden? [duplicate] 9 answers i have following code: var tz = timezoneinfo.findsystemtimezonebyid("central standard time"); dateanalyzed_copper = records.dateanalyzed_copper.hasvalue ? timezoneinfo.converttimetoutc(records.dateanalyzed_copper.value, tz) : null, ...... note dateanalyzed_copper nullable datetime. i following message type of conditional expression cannot determined because there no implicit conversion between 'system.datetime' , '<null>' you should cast either null nullable datetime: dateanalyzed_copper = records.dateanalyzed_copper.hasvalue ? timezoneinfo.converttimetoutc(records.dateanalyzed_copper.value, tz) : (datetime?)null or datetime value returned converttimetoutc : dateanalyzed

What is the canonical way to isolate unit tests in Python with assertion-style tests? -

i asked question , realized i'd know if there's way achieve 'expectation' isolation assertion-style tests. i've copy , pasted simple example of mean 'expectation' isolation. i'm relatively new python, coming ruby/javascript , having testing libraries rspec , jasmine has provided me ability isolate 'expectations' when testing single function. since there doesnt seem 'expectation'-style library python actively maintained, wondering if there's way achieve equivalent testing style either unittest or pytest (the 2 popular python testing libraries understand). foo.py class foo(): def bar(self, x): return x + 1 expectation-style/describe-it test_foo.py describe foo: describe self.bar: before_each: f = foo() 'returns 1 more arguments value': expect f.bar(3) == 4 'raises error if no argument passed in': expect f.bar() raiseerror uni

javascript - Kinetic.js get shape hit region with color change -

first of all, have images different shapes , have recolour them, , set hit region (for onclick event) when mouse on shape. after investigate problem separately, have found both solutions, dont know how use both together. -to use shape hit region, use .cache(), store image on cache , redraw without transparent pixels. -to change color, iterate on imagedata pixels, change them 1 one inside loop. for testing, i'm using original blue image (.png format) , want red image hit regions set properly, i'm using kinetic-v5.0.2. this code. function makekineticimage(imageobj){ var dimage = new kinetic.shape({ scenefunc: function (context) { context.beginpath(); console.log("scenefunc"); var x = 100; var y = 100; context.drawimage(imageobj, x, y, imageobj.width, imageobj.height); var imagedata = context.getimagedata(x, y, imageobj.width, imageobj.height); var data = i
