javascript - How to drag one or more items to an element using both Draggable and Selectable JQuery -


i'd know how drag 1 or more items (individual person records in case, via avatar photo) target (in case list of cities) , update database dragged items details of item dragged to.

i have working single items @ moment.

i have sidebar list of locations retrieve database entityframework:

<ul> <li class="droppable">     <span>sydney</span> </li> <li class="droppable">     <span>brisbane</span> </li> <li class="droppable">     <span>melbourne</span> </li> </ul>

in main window have grid of people's images , i'm using jquery ui selectable enable these selected:

<ul class="people-list" id="selectable">     @foreach (var item in model.people)     {         <li>             <img src="@item.photo" style="width:100%" class="img-polaroid" />                         </li>     } </ul>   $(function () {     $("#selectable").selectable({         selected: function (event, ui) {             if ($(ui.selected).hasclass('click-selected')) {                 $(ui.selected).removeclass('ui-selected click-selected');              } else {                 $(ui.selected).addclass('click-selected');              }         },         unselected: function (event, ui) {             $(ui.unselected).removeclass('click-selected');         }     });  });

what i'd do, once user has selected 1 or more people, them able drag selected people 1 of locations, , update database.

so if user drags personid 4,5 , 9, 'sydney' need update database asyncronously perform this.

i've added jquery draggable , droppable , can drag individual people 1 of locations, , update database, can't work selectable allow multiple items selected.

$(function () {     $(".img-polaroid").draggable({         containment: "document",         helper: 'clone',         opacity: 0.70,         zindex: 10000,      });     $(".droppable").droppable({         hoverclass: "ui-state-hover",         tolerance: "pointer",         drop: function (event, ui) {             $.ajax({                 type: "post",                 url: '/person/updatelocations/' + $(this).attr("id") + '|' + $(ui.draggable).attr("id"),                 success: function (data) {                     $('.draggable').draggable('destroy');                     $('#successmsg').empty();                     $('#successmsg').append(data);                     $('#successdiv').show();                     $('.draggable').draggable({ revert: true });                 }             });         }     }); });

i find out .selectable() , .draggable() not working on same element. suggestion create own multi-select behaviour.

embedding value (id) html elements

embed ids, value, html elements accordingly both cities , persons, eq : <li class="droppable" data-val="sydney"><span>sydney</span> </li> , <img src="" class="img-polaroid" data-val="4"/>.

imitating multi-select

every selected element tagged specific class, defined in selectedclass = "ui-selected". class toggled click event. element may not selected on drag event, therefore need add selectedclass on draggable.start.

drag

.draggable works on single dragged element (cmiiw), move selected element changing top , left properties of elements. set position=relative of #selectable element.

drop

actions need done on droppable.drop callback : prepare data , perform ajax request. if ajax request succeed selectable elements removed , update message. if ajax request failed selectable elements going placed on original position.

please take on example : http://jsfiddle.net/marson/zscab/131/. hope helps.

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod

thorough guide for profiling racket code -

did googling ("racket profiling", "racket measure performance"), didn't find , there no examples in docs. did google "profile" search on htdp - no luck. (profile (f ...)) output isn't obvious other small snippets. ideally want python's python -m cprofile usage examples. when search "python profiling", both duckduckgo , google give top result: 26.4. python profilers . (although scanned quickly, seems more of reference "thorough usage guide" examples. if had else in mind, perhaps please link that?) the equivalent racket documentation be: profile: statistical profiler . a usage example: #lang racket (require profile) (profile-thunk (thunk (function-to-profile arg0 arg1) )) here (thunk e) convenience (lambda () e) . bigger example: #lang racket (module mod racket (provide f) (define (f) (for/list ([i 10000]) i))) (require (prefix-in mod: 'mod)) (define (f) (for ([i 10000
