ComboBox that shows a tree in the dropdown - javascript

I want to write a ComboBox which lets the user type in a query and at the same time lets him select a value from a tree. I have tried writing a tree-select but if I change the code to inherit from dijit.form.ComboBox instead of a dijit.form.Select, the code breaks.
Here is what I had tree for tree select:
dojo.declare('TreeSelect',dijit.form.Select,{
constructor: function(widgetArgs){
this.tree = widgetArgs.tree || new FC_Tree();
this.initTree = widgetArgs.initTree;
if(dojo.isFunction(this.initTree))
this.initTree();
},
postCreate: function(){
this.inherited(arguments);
this.option = {label: '', value: 'NoValue'};
this.tree.option = this.option;
this.addOption(this.option);
dojo.connect(this.tree,'onClick',this,'closeDropDown');
dojo.connect(this.tree,'itemSelected',this,'selectOption');
},
selectOption: function(opt){
this.option.label = opt.label || opt;
this.option.value = opt.value || opt;
this.option.id = opt.id || opt;
this.set('value',this.option);
},
_getMenuItemForOption: function (option){
return this.tree;
},
openDropDown: function(){
this.tree.refresh();
this.inherited(arguments);
},
clear: function(){
this.tree.clear();
this.tree.option.value = '';
this.tree.option.label = '';
this.tree.option.id = '';
this.set('value',this.tree.option);
},
initializeTree: function(treeData) {
// Init the tree only if needed
dojo.forEach(treeData, function(field) {
var store = this.tree.model.store;
store.newItem(field);
}, this);
},
setOpenCallback: function(callback){
this.tree.setOpenCallback(callback);
},
resetTree: function() {
var store = this.tree.model.store;
store.fetch( { query: { id: "*" },
onItem: function(item) {
store.deleteItem(item);
}
});
}
});
I had tried replacing the code for combobox like this:
dojo.declare('TreeSelect',dijit.form.ComboBox,{
Please help me rectify it.
Thanks in advance!
Adding the code for FC_Tree:
dojo.declare('FC_Tree',dijit.Tree,{

openCallback: null,
constructor: function(){

var forest_store = new FC_DataStore({id: 'id', label: 'label'});
this._storeloaded = false;
dojo.connect(forest_store,'loaded',this,function(){this._storeloaded = true;})
this.model = new dijit.tree.ForestStoreModel({store:forest_store});
}
},
setOpenCallback: function(callback){
this.openCallback = callback;
},
option: {},
itemSelected: function(item){
},
onClick: function(item, node, evt){
var store = this.model.store;
get = function(){
return store.getValue(item, "isDir");
};
// on folder click mark it unselectable
if(get("isDir"))
{
this.isExpanded = true;
this.isExpandable = true;
}
else
{ //In case the item has 'onClick' delegate execute it and assign the output to 'selItem'
var selItem = (item.onClick && item.onClick[0])? item.onClick[0](this.model.store,item.parentID[0]):item.id[0];
this.option.id = item.id;
this.option.value = item.value;
this.option.label = item.label;
this.itemSelected(this.option);
}
},
onOpen: function(item, node){
if(this.rootNode.item == item){
return this.inherited(arguments);
}
var data = (this.openCallback != null) ? this.openCallback(item, node) : {};
if(!data.length){
return this.inherited(arguments);
}
FC_Comm.when(data,{
onCmdSuccess: dojo.hitch(this,function(data){
var store = this.model.store;
var children = store.getValues(item, 'children');
dojo.forEach(children, function(child) {
// don't delete child if doNotDelete flag is true

store.deleteItem(child);
});

Possibly you will find inspiration / answer in this fiddle
The recursiveHunt and selectTreeNodeById functions are logic to seek out the path of an item by its id. Its quite excessive and you may find a better solution (dont know 100% what data your json is like)..
Basically, use FilteringSelect and reference the tree in this object. Also for Tree, reference the select.
Then for your tree, hook into load function (also called on refresh afaik) and in turn for the select, use onBlur to initate selecting treenode.
var combo = new dijit.form.FilteringSelect({
onBlur: function() {
// called when filter-select is 'left'
if (this.validate()) {
// only act if the value holds an actual item reference
var id = this.get("value");
var name = this.get("displayedValue");
this.tree.selectNode(id);
}
}
});
var tree = new dijit.Tree( { ....
onLoad: function() {
combostore.setData(this.model.store._arrayOfAllItems);
},
onClick: function(item) {
// uses 'this.combo', must be present
// also, we must have the same 'base store' for both combo and model
var _name = this.model.store.getValue(item, this.combo.searchAttr);
this.combo.set("item", item, false, _name);
},
selectNode: function(lookfor) {
selectTreeNodeById(this, lookfor);
},
combo: combo // <<<<<<
});
combo.tree = tree // <<<<<<
Make sure that the model has a rootId, and also that your select.searchAttr matches tree.model.labelAttr. See working sample on the fiddle

How can i open a form always in Edit mode , for a particular model

I have a model say 'my.attendance' , also have a form view for this which contains some attendance details.What i need is when i open this form view it should always open in Edit mode.So i can directly enter the attendance without clicking Edit button each time.

You have to extend the ViewManager to achieve this.
odoo.define('my_module.view_manager', function (require) {
"use strict";
var ViewManager = require('web.ViewManager');
ViewManager.include({
custom_events: {
execute_action: function(event) {
var data = event.data;
this.do_execute_action(data.action_data, data.env, data.on_closed)
.then(data.on_success, data.on_fail);
},
search: function(event) {
var d = event.data;
_.extend(this.env, this._process_search_data(d.domains, d.contexts, d.groupbys));
this.active_view.controller.reload(_.extend({offset: 0}, this.env));
},
switch_view: function(event) {
if ('res_id' in event.data) {
this.env.currentId = event.data.res_id;
}
var options = {};
console.log(event.data)
if (event.data.view_type === 'form' && !this.env.currentId) {
options.mode = 'edit';
} else if (event.data.mode) {
options.mode = event.data.mode;
}
// Extra added code
if (event.data.model){
if (event.data.model == 'my.model'){ // Checking the particular model.
options.mode = 'edit';
}
}
this.switch_mode(event.data.view_type, options);
},
env_updated: function(event) {
_.extend(this.env, event.data);
},
push_state: function(event) {
this.do_push_state(event.data);
},
get_controller_context: '_onGetControllerContext',
switch_to_previous_view: '_onSwitchToPreviousView',
},
});
});

backbone drag and drop - getting dropped data

I'm relatively new to programming and this is my first time posting on here, so sorry in advance if this isn't presented correctly.
I'm building a health tracker app with Backbone JS. I am retrieving data from the Nutritionix API and populating a view on the left side of the screen with that data. I want the user to be able to drag an item from the populated view and drop it in a view to the right in which case a calorie counter will increase. I also need that data to persist so that when the user closes and reopens the app their selected data in the view will remain the same.
I've implemented the drag and drop feature just fine. I am now trying to make it so that when the user drops an item from the left view into the right view a collection is created that only contains the data in the right view. I believe that I need to do this so I can persist the data. Right now, I am having trouble transferring the API data along into the right view. Here are the relevant code snippets:
appView:
var app = app || {};
var ENTER_KEY = 13;
app.AppView = Backbone.View.extend({
el: '#health-app',
urlRoot: 'https://api.nutritionix.com/v1_1/search/',
events: {
'keypress': 'search',
'click #clearBtn': 'clearFoodList',
'drop .drop-area': 'addSelectedFood',
// 'drop #selected-food-template': 'addSelectedFood'
},
initialize: function() {
this.listenTo(app.ResultCollection, 'add', this.addFoodResult);
// this.listenTo(app.SelectedCollection, 'add', this.addSelectedFood);
app.ResultCollection.fetch();
app.SelectedCollection.fetch();
this.clearFoodList()
},
addFoodResult: function(resultFood) {
var foodResult = new SearchResultView({
model: resultFood
});
$('#list').append(foodResult.render().el);
},
// addSelectedFood: function(selectedFood) {
// // var selectedFoodCollection = app.SelectedCollection.add(selectedFood)
// console.log(app.SelectedCollection.add(selectedFood))
// },
clearFoodList: function() {
_.invoke(app.ResultCollection.toArray(), 'destroy');
$('#list').empty();
return false;
},
search: function(e) {
var food;
//When the user searches, clear the list
if($('#search').val() === '') {
_.invoke(app.ResultCollection.toArray(), 'destroy');
$('#list').empty();
}
//Get the nutrition information, and add to app.FoodModel
if (e.which === ENTER_KEY) {
this.query = $('#search').val() + '?fields=item_name%2Citem_id%2Cbrand_name%2Cnf_calories%2Cnf_total_fat&appId=be7425dc&appKey=c7abd4497e5d3c8a1358fb6da9ec1afe';
this.newUrl = this.urlRoot + this.query;
var getFood = $.get(this.newUrl, function(data) {
var hits = data.hits;
var name, brand_name, calories, id;
_.each(hits, function(hit){
name = hit.fields.item_name;
brand_name = hit.fields.brand_name;
calories = hit.fields.nf_calories;
id = hit.fields.item_id;
food = new app.FoodModel({
name: name,
brand_name: brand_name,
calories: calories,
id: id
});
//If the food isn't in the ResultCollection, add it.
if (!app.ResultCollection.contains(food)) {
app.ResultCollection.add(food);
}
});
food.save();
});
}
}
});
breakfastView:
var app = app || {};
app.BreakfastView = Backbone.View.extend({
el: '#breakfast',
attributes: {
'ondrop': 'ev.dataTransfer.getData("text")',
'ondragover': 'allowDrop(event)'
},
events: {
'dragenter': 'dragEnter',
'dragover': 'dragOver',
'drop': 'dropped'
},
initialize: function() {
this.listenTo(app.SelectedCollection, 'change', this.addSelectedFood);
},
render: function() {},
addSelectedFood: function(selectedFood) {
// var selectedFoodCollection = app.SelectedCollection.add(selectedFood)
console.log(app.SelectedCollection.add(selectedFood))
},
dragEnter: function (e) {
e.preventDefault();
},
dragOver: function(e) {
e.preventDefault();
},
dropped: function(ev) {
var data = ev.originalEvent.dataTransfer.getData("text/plain");
ev.target.appendChild(document.getElementById(data));
// console.log(app.SelectedCollection)
this.addSelectedFood(data);
},
});
new app.BreakfastView

jquery: can find element, but unable to remove it

I've got stuck here with jQuery remove method. Here's a piece of code ...
clearTemplate : function(contentContainer) {
var container = $('body').find('#' + contentContainer);
if (container.length !== 0) {
console.log(container.length);
container.remove();
console.log(container.length);
}
}
Script can easily find '#'+contentContainer in DOM but is unable to remove it. It has no problem with removing children elements of container object as well.
Console.log returns (obviously) : 1 and 1
Container is also dynamically loaded into DOM.
Here's a bigger piece ...
var TemplateClass = {
mainDiv : $('<div>').attr('id',contentContainer),
setData : function(result, images, template, link) {
this.result = result;
this.images = images;
this.template = template;
this.link = link;
},
readyTemplate : function() {
var that = this;
$.each(this.result, function () {
data = that.result[0];
$(that.mainDiv).loadTemplate(that.template, data, {
append: true
});
});
return this.mainDiv;
},
clearTemplate : function(contentContainer) {
var container = $('body').find('#' + contentContainer);
if (container.length !== 0) {
console.log(container.length);
container.remove();
console.log(container.length);
}
}
}
I'm able to live without removing this object, but it's just not right.

jQGrid Column Chooser Modal Overlay

Looking off this example, notice how clicking on the Search button brings up a modal form with a darkened overlay behind it. Now notice how clicking on the Column Chooser button brings up a modal form but no overlay behind it.
My question is: how do I get the dark overlay to appear behind my Column Chooser popup?

There are currently undocumented option of the columnChooser:
$(this).jqGrid('columnChooser', {modal: true});
The demo demonstrate this. One can set default parameters for the columnChooser with respect of $.jgrid.col too:
$.extend(true, $.jgrid.col, {
modal: true
});
Recently I posted the suggestion to extend a little functionality of the columnChooser, but only a part of the changes are current code of the jqGrid. Nevertheless in the new version will be possible to set much more jQuery UI Dialog options with respect of new dialog_opts option. For example the usage of the following will be possible
$(this).jqGrid('columnChooser', {
dialog_opts: {
modal: true,
minWidth: 470,
show: 'blind',
hide: 'explode'
}
});
To use full features which I suggested you can just overwrite the standard implementation of columnChooser. One can do this by including the following code
$.jgrid.extend({
columnChooser : function(opts) {
var self = this;
if($("#colchooser_"+$.jgrid.jqID(self[0].p.id)).length ) { return; }
var selector = $('<div id="colchooser_'+self[0].p.id+'" style="position:relative;overflow:hidden"><div><select multiple="multiple"></select></div></div>');
var select = $('select', selector);
function insert(perm,i,v) {
if(i>=0){
var a = perm.slice();
var b = a.splice(i,Math.max(perm.length-i,i));
if(i>perm.length) { i = perm.length; }
a[i] = v;
return a.concat(b);
}
}
opts = $.extend({
"width" : 420,
"height" : 240,
"classname" : null,
"done" : function(perm) { if (perm) { self.jqGrid("remapColumns", perm, true); } },

selector.data('dialog').uiDialog.resizable("option", "alsoResize",
resizeSel + ',' + resizeSel +'>div' + ',' + resizeSel + '>div>div.ui-multiselect');
}
});
In the case you can continue to use the original minimized version of jquery.jqGrid.min.js and the code which use can be just $(this).jqGrid('columnChooser');. Together with all default settings it will be like
$.extend(true, $.ui.multiselect, {
locale: {
addAll: 'Make all visible',
removeAll: 'Hidde All',
itemsCount: 'Avlialble Columns'
}
});
$.extend(true, $.jgrid.col, {
width: 450,
modal: true,
msel_opts: {dividerLocation: 0.5},
dialog_opts: {
minWidth: 470,
show: 'blind',
hide: 'explode'
}
});
$grid.jqGrid('navButtonAdd', '#pager', {
caption: "",
buttonicon: "ui-icon-calculator",
title: "Choose columns",
onClickButton: function () {
$(this).jqGrid('columnChooser');
}
});
The demo demonstrate the approach. The main advantage of the changes - the really resizable Column Chooser:
UPDATED: Free jqGrid fork of jqGrid, which I develop starting with the end of 2014, contains of cause the modified code of columnChooser.

I get the following error while trying the code on the mobile device.
Result of expression 'selector.data('dialog').uiDialog' [undefined] is not an object.
The error points to the following line of code.
selector.data('dialog').uiDialog.resizable("option", "alsoResize", resizeSel + ',' + resizeSel +'>div' + ',' + resizeSel + '>div>div.ui-multiselect');
When I inspect the code, I find that the data object does not have anything called uiDialog.

just been looking thru the code, try adding this line:
jqModal : true,
to this code:
$grid.jqGrid('navButtonAdd', '#pager', {
caption: "",
buttonicon: "ui-icon-calculator",
title: "Choose columns",
onClickButton: function () {
....
like this:
$grid.jqGrid('navButtonAdd', '#pager', {
caption: "",
buttonicon: "ui-icon-calculator",
title: "Choose columns",
jqModal : true,
onClickButton: function () {
....

How can I show only matching items at the top of the list and hide not matching during input typing?
Thanks!

You can do it using onShow and onHide handlers, of course.
See here: http://jsfiddle.net/ypfPY/3/
var myFilter = new ElementFilter('search-term', '#my-list li', {
trigger: 'keyup',
cache: false,
onShow: function(element) {
element.setStyle('display', 'block');
},
onHide: function(element) {
element.setStyle('display', 'none');
}
});
Frankly speaking, I encountered a set of bugs in ElementFilter source (bug on firstly retrieving "showing" and false instead of true for matchOverride when showing all items), so, you better get source from here:
var ElementFilter = new Class({
// implements
Implements: [Options,Events],
// options
options: {
cache: true,
caseSensitive: false,
ignoreKeys: [13, 27, 32, 37, 38, 39, 40],
matchAnywhere: true,
property: 'text',
trigger: 'mouseup',
onStart: $empty,
onShow: $empty,
onHide: $empty,
onComplete: $empty
},
//initialization
initialize: function(observeElement,elements,options) {
//set options
this.setOptions(options);
//set elements and element
this.observeElement = document.id(observeElement);
this.elements = $$(elements);
this.matches = this.elements;
this.misses = [];
//start the listener
this.listen();
},
//adds a listener to the element (if there's a value and if the event code shouldn't be ignored)
listen: function() {
//add the requested event
this.observeElement.addEvent(this.options.trigger,function(e) {
//if there's a value in the box...
if(this.observeElement.value.length) {
//if the key should not be ignored...
if(!this.options.ignoreKeys.contains(e.code)) {
this.fireEvent('start');
this.findMatches(this.options.cache ? this.matches : this.elements);
this.fireEvent('complete');
}
}
else{
//show all of the elements - changed to true
this.findMatches(this.elements,true);
