i'm brand new javascript, dojo , html , i've searched everywhere examples of , cannot find any. i have map feature points , find task highlight feature points on map, , display them in grid it's field attributes. works great when specify search field as: findparams.searchfields = ["location"]; but if add: findparams.searchfields = ["location", "model_num"]; the grid displays results multiple fields (ie. searching attributes in location "a" find attributes in model_num containing letter "a"). decided add drop down menu select specify field search in (one @ time) results more precise. so added following dijit: <select id="fieldselect" data-dojo-type="dijit/form/select" name="fieldselect"> <option value="" selected="selected">select field</option> <option value="model_num">model number</option> ...

i have extjs gridanel viewmodel store bound it. model of store defined model field references model. for sake of simplicity here's example: ext.define('user', { extend: 'ext.data.model', fields: ['name'] }); ext.define('order', { extend: 'ext.data.model', fields: ['date', { name: 'user', reference: 'user' }] }); viewmodel: { store: { order: { model: 'order', } } } in gridpanel have 2 columns. in 1 column, dataindex: 'date' works correctly, displaying date. however, in second column want display name of user. have no idea how that. user field on object declaring dataindex: user doesn't work. tried dataindex: {user.name} doesn't work either. tried bind: { data: '{user.name}' } also no avail. have found solution using renderer config of column ugly , beats point of having model reference if h...

i'm porting piece of code written linux , compiled gcc v4.8.2 (using -std=c++11) windows. part of overloaded operator<< msvc++ 2013 doesn't agree with. condensed example below. we've defined custom stream class supports standard stream manipulator functions. reason we've overloaded operator<< accepts function pointer second argument. if define templated overload of operator<< . msvc++ complains: error c2676: binary '<<' : 'foobar' not define operator or conversion type acceptable predefined operator but if specify type of second argument std::ostream instead of templated std::basis_ostream<..,..> code works expected. at first thought had messed template arguments. however, if define arbitrary template function instead of overload of operator<< code compiles fine. what's going on here? example #include "stdafx.h" #include <iostream> #include <sstream> #incl...

explanation: ajax load content div "content" without refreshing page. if div "content" longer 300px - hide "soc_menu_l". script runs absolutely ok on page's refresh: if try update div's height without refreshing page - nothing happens. check heights of div in mozilla's inspector - height changed, script not react it. how can make script "watch" height continuously , infinitely? $(function () { if ($('#content').height() > 300) { $('.soc_menu_l').hide(); } }); or maybe should call script each time after "content"-div loaded? option 1 add event listener: $('#change1').click(function() { $('#content').css({"height":"600px"}); $(window).fireevent('change1'); }); $(window).addeventlistener('change1', function() { if($('#content').height() > 300){ $('.soc_menu_l').hide(); } });

considering below code, abstract class abstractclass { public abstract void abstractmethoda(); public void concretemethoda() { //some operation concretemethodb(); } } public void concretemethodb() { //huge code unrelated class abstractmethoda(); } } class derivedclass : abstractclass { public void abstractmethoda() { //some operation } } now wish move concretemethodb() separate class , make call method concretemethoda() in abstract class. since concretemethodb() uses abstract method abstractmethoda() implemented in derivedclass, unable access method abstractmethoda() new class? idea on how resolve this? why don't make this static class helper { public static void concretemethodb(abstractclass caller) { //huge code unrelated class caller.abstractmethoda(); } } and in abstractclass abstract class abstractclass { public abstract void abstractmethoda(); public void concretemethoda() { //some operation helper.concretemethodb(...
