var = function () { this.someproperty = 0; }; var = new a(); the variable a object. call a ? class? a called constructor function . well, specifically, a variable refers constructor function, don't kind of mintuiae. sometimes people call these "classes," because constructor functions aid in producing classes of objects (in general sense, e.g., objects common characteristics). javascript doesn't have classes in class-based oop sense java or c#, has different inheritance mechanism called prototypical inheritance . (this true in es2015 , beyond, keyword class used define constructor function, properties of prototype assigns objects when used new , , properties on function referring other functions ["static methods"].)

i have a, let's say, 250 rows, devided 25 pages. 10 rows on each page. if i'm on first page, , click on third row, rowindex = 2. if i'm on second page , click on first row, logically i'm supposed rowindex of 11th page, should rowindex = 10. i'm getting rowid = 0. how can fix that? in truth correct behaviour. because when click on first row, first index in table. doesn't know data on pages because don't exists (why load data don't need? can performance issue) so if want behaviour describing, have select page number , calculate that. something like: rowindex = getrowindex ... page = grid.datasource.page(); rowindex = (page - 1) * 10 + rowindex; here demo

i developing financial algorithms using java. have complex data structure many properties need updated during life time of algorithm. data structure updated more 1000 times ... to improve performance get(search)/update/insert decided use treemap container quite efficient in regard. now comes challenging part. need update data-structure properties need retrieve container requires: check if container has object if yes, object, else create new object , add map update object if present in container this process takes 3 x log(n) i.e check, , put. want in single log(n) time. for that, solution is: i add object in map ( insert/update/get ) using put . put returns old object, update current object old values, solves log(n) different object lost reference previous object because new value replaced in map. is there better solution or better container updating datastructure. can use list , use binary search of collections need sort datastructure again list not sorted.

i using react-bootstrap in project. need open multiple dialog. there way achieve this? note: there answers bootstrap here not work in react-bootstrap. thanks. it depends on want achieve. have multiple react bootstrap modal dialogs , have embedded dialogs, modal dialog shows popup error message. can define state variable, this: this.state = {showmodal1:true, showmodal2:false,...} in render function can this: render() { return( <div> <modal show={this.state.showmodal1}> modal 1 text comes here </modal> <modal show={this.state.showmodal2}> modal 2 text comes here </modal> </div> ); } in code above, if both showmodal1 , showmodal2 true, both modal dialogs , second above first one.

is ok delete void pointer in below program. class sample { public: int intval; float floatval; }; main() { sample *samobj = new sample(); void *vptr = samobj; delete vptr; } this sample program have written. actually, in project have no other way doing similar thing. similar code in .h interface file, , when include file , compile other components, compiler gives warning message "warning: deleting 'void*' undefined", doubt since have assigned void pointer sample object type, isn't safe delete pointer? calling delete on void pointer undefined behavior [ref ] . should not @ all. not calling delete on void pointer on pointer of type sample fine.

i have lot of independent spring beans in project (classes annotated @component -- not lazily initialized ). wanted know weather beans initialized serially or parallely? asking because beans modify common data structure on initialization , wanted know weather data structure should made thread-safe. spring version used:- 4.2 i reading open issues on spring jira website:- according https://jira.spring.io/browse/spr-9887 seems parallely initialized but according https://jira.spring.io/browse/spr-8767 seems serially initialized. spring initialises beans in serial. there nothing says initialised in parallel. in fact, ticket cite ( https://jira.spring.io/browse/spr-9887 ) closed ticket because it's duplicate of https://jira.spring.io/browse/spr-8767 . ticket unresolved , targetted release of spring 5.0 in future, nothing says beans initialised in parallel!

i've got list<string> names; , has 700 000 names in it. how can join every 500 strings (using separator ",") , add them new list<string> abc; so want have 1 list<string> , hold 1400 joined strings. abc[0]= first 500 names, abc[1]= next 500 names , on. with morelinq batch (or any other batch implementation ): var abc = names.batch(500).select(x => string.join(",", x)).tolist(); note: grouping operator not streaming operator (as tolist). means 700k strings should enumerated , keys should calculated each item, , each items should stored in internal groups. , cost time , resources. batching streaming , not store items internally. stores current batch. batching if not convert results list , can process batches 1 one faster , save memory.

i have followed this tutorial without problems, start using sass. can see includes part using compass mixins . have compiled .scss files including @import compass/css3/box-sizing without problems. now want compile .scss files, using gulp. have followed this tutorial. have these files: //src/defaultbundle/resources/public/assets/css/main.scss form { span { color: red; } } var gulp = require('gulp'); var sass = require('gulp-sass'); gulp.task('default', function() { gulp.src('src/defaultbundle/resources/public/assets/css/main.scss') .pipe(sass()) .pipe(gulp.dest('web/css')); }); so when run $ gulp latter tutorial says, .css file. the problem : if add @import compass/css/box-sizing @ top of .scss file , error when running $ gulp : [13:12:01] working directory changed /var/www/my_project [13:12:01] using gulpfile /var/www/my_project/gulpfile.js [13:12:01] starting 'default'...

i'm wondering, if it's possible : i have new object: // create new object form existing code var v1 = $("#div1").getmyobject(); now can use v1 object, example: v1.start(); now question is: have variable, example: var num = 1; now want find way select v1 object, using num variable (this of course not work, want show, need): v+num.start() so see, want use var num, , assign var object name, later use. i'm asking, because, need select proper object in loop, , want select dynamicly. thank advice. instead of having objects like: v1, v2, .... you should have: v[1], v[1], .... then can use v[1] = $("#div1").getmyobject(); v[num].start();

there code double max = pow(2,1000); double test = max/10; the result test wrong result. want know how happened? the issue precision of float numbers. stored in binary format , double can store 53+1 bits in mantissa. when divide such big number 10, lose of bits it's not possible express division precisely in binary number. actually it's impossible store 1/10 precisely, here original power of 2 doesn't matter much. edit: regarding other answers - exponent can store 11 bits in double, it's able handle 2^1000.
