I have a TreeStore that you can drill into. It's only two levels deep. When you get to the second level and you click on a leaf it takes you to a detail card.
How do I, in the detail card, show the full path?
So say I have;
- A
- 1
- 2
- B
- 1
- 3
- C
- 5
- 2
So when I click on B and then 3 I want to have "B" and "3" ideally in a Javascript variable that I can then pass to a WebService.
I believe SenchaTouch has no built in functionality for this.
You can listen for the itemtap event and then store the title of your item in an array.
When you show your detailcard you could pass this array to you webservice and show the joined array in your card.
Unfortunately i don't know what your code looks like and if you use the MVC approach but it would probaply something like this:
breadcrumbs = []
onItemTap = function( list, target, record ){
breadcrumbs.push( record.get('title') );
}
onLeafItemTap = function() {
breadcrumpsStr = breadcrumbs.join('->');
// send them to your webservice
// set in your detailCard
breadcrumps = []
}
When you provide your code I could help you more.

Currently in ArcGIS Online if multiple items exist in a single point the template is shown like this
Will I be able to view the details with the number of elements as a part of the template like this
You can retrieve the number of selected features using Popup.featureCount.
The following CodePen uses this property to provide a dynamic PopupTemplate.title: https://codepen.io/arnofiva/pen/5b532f8577d097107cf8040da57e0b97
var template = layer.popupTemplate;
var defaultTitle = template.title;
// Compute popup title before it is shown
template.title = function() {
var total = view.popup.featureCount;
if (total > 1) {
return defaultTitle + " - Count: " + total + "";
} else {
return defaultTitle;
}
}

I use vue.js now for about a month and wanted to use the vue-grid-layout to build up a grid 8x4. Is there a possibility to exchange the widgets by each other or is it only possible to put it in between and push it to the bottom?
Example by dragging c to a:
a b c d
gets
c b d
a
But what I want to achieve is:
a b c d
gets
c b a d
What is the best way to implement such a behavior?
Do I have to use a different grid engine?
if so, which one would you prefer?
Thx in advance

In order to achieve this effect, you are going to have to orchestrate several events on several components, and signal from the children to the parent when certian things happen.
We have 2 components involved in this operation - the parent component and the draggable child component (which has multiple instances). In the parents template we have the following...
<div id="dropTargetDiv" #drop.prevent="drop" v-on:startIndex="setStartIndex(value)" v-on:targetIndex="setTargetIndex(value)">
<draggable-component v-for="(itemData, index) in dataArray" :itemData="itemData" index="index"/>
</div>
The parent also has these methods...
setStartIndex(value) {
this.startIndex = value;
},
setTargetIndex(value) {
this.targetIndex = value;
},
drop(event) {
this.swapElements(this.startIndex, this.targetIndex);
},
swapElements(start, target) {
// Clone the original array
var newArray = JSON.parse(JSON.stringify(this.dataArray));
// Swap elements
var startElement = newArray[start];
var targetElement = newArray[target];
newArray[target] = startElement;
newArray[start] = targetElement;
// Update the UI
this.dataArray = newArray;
}
In the child component, on its root element, we have the following...
<div class="draggableItem" draggable="true" #dragstart="$emit('startIndex', this.index)" #dragenter.prevent="$emit('targetIndex', this.index)">
If you see that the target index isn't being set correctly, you may want to replace the #dragenter.prevent with #dragover.prevent.
This should work - comments are welcome. You will need to drop on top of another child, not between them.
I just started using dgrid, and going through the dTunes sample, I'm unable to find the id associated with each row in the list. This is pretty remedial on my part, but how would I also get the id I sent from the datasource?
define([
'require',
'dgrid/List',
'dgrid/OnDemandGrid',
'dgrid/Selection',
'dgrid/Keyboard',
'dgrid/extensions/ColumnHider',
'dojo/_base/declare',
'dojo/_base/array',
'dojo/Stateful',
'dojo/when',
'dstore/RequestMemory',
'put-selector/put',
'dojo/domReady!'
], function (require, List, Grid, Selection,
Keyboard, Hider, declare, arrayUtil, Stateful,
when, RequestMemory, put) {
var cstsNode = put(listNode, 'div#cstsCars');
...
var cstsList = new TunesList({}, cstsNode);
var dataCSTS = new RequestMemory({ target: require.toUrl('./dataCSTS.json') });
...
dataCSTS.fetch().then(function (cars) {
cstsCars = arrayUtil.map(cars, pickField('Description'));
cstsCars.unshift('All (' + cstsCars.length + ' CSTS Cars' + (cstsCars.length !== 1 ? 's' : '') + ')');
cstsList.renderArray(cstsCars);
});
...
cstsList.on('dgrid-select', function (event) {
var row = event.rows[0];
console.log(row.id); // shows row number. How do I get the real id or other fields?
console.log(row.data); // shows row text that is displayed ("sample text 1")
console.log(row.data.id); // undefined
});
Here is a snippet of sample data like I'm supplying:
[{"id":"221","Description":"sample text 1"},
{"id":"222","Description":"sample text 2"},
{"id":"223","Description":"sample text 3"}]
I'd like to see the id. Instead, row.id returns 1,2 and 3, ie the row numbers (or id dgrid created?).
You haven't really shown a complete example, but given that you're using a store anyway, you'd have a much easier time if you let dgrid manage querying the store for you. If you use dgrid/OnDemandList (or dgrid/List plus dgrid/extensions/Pagination), you can pass your dataCSTS store to the collection property, it will render it all for you, and it will properly pick up your IDs (since Memory, and RequestMemory by extension, default to using id as their identity property).
The most appropriate place to do what you're currently doing prior to renderArray would probably be in the renderRow method if you're just using List, not Grid. (The default in List just returns a div with a text node containing whatever is passed to it; you'll be passing an object, so you'd want to dig out whatever property you actually want to display, first.)
If you want a header row, consider setting showHeader: true and implementing renderHeader. (This is false in List by default, but Grid sets it to true and implements it.)
You might want to check out the Grids and Stores tutorial.
I think the problem might be that I was modeling my code based on the dTunes sample code, which has 3 lists that behave a little differently than a regular grid.
For now, I'm using the cachingStore that is available in the lists. So the way I get the id:
cstsList.on('dgrid-select', function (event) {
var row = event.rows[0];
var id = storeCSTS.cachingStore.data[row.id - 1].id; // -1 because a header was added
console.log(id);
});
I'm not sure whether this will work if I ever try to do sorting.
I have a ctrl that pulls a json array from an API. In my code I have an ng-repeat that loops through results.
This is for a PhoneGap mobile app and I'd like to take a single element from the array so that I can use it for the page title.
So... I'm wanting to use 'tool_type' outside of my ng-repeat.
Thanks in advance - I'm just not sure where to start on this one.
Example json data
[{ "entry_id":"241",
"title":"70041",
"url_title":"event-70041",
"status":"open",
"images_url":"http://DOMAIN.com/uploads/event_images/241/70041__small.jpg",
"application_details":"Cobalt tool bits are designed for machining work hardening alloys and other tough materials. They have increased water resistance and tool life. This improves performance and retention of the cutting edge.",
"product_sku":"70041",
"tool_type": "Toolbits",
"sort_group": "HSCo Toolbits",
"material":"HSCo8",
"pack_details":"Need Checking",
"discount_category":"102",
"finish":"P0 Bright Finish",
"series_description":"HSS CO FLAT TOOLBIT DIN4964"},
..... MORE .....
Ctrl to call API
// Factory to get products by category
app.factory("api_get_channel_entries_products", function ($resource) {
var catID = $.url().attr('relative').replace(/\D/g,'');
return $resource(
"http://DOMAIN.com/feeds/app_productlist/:cat_id",
{
cat_id: catID
}
);
});
// Get the list from the factory and put data into $scope.categories so it can be repeated
function productList ($scope, api_get_channel_entries_products, $compile) {
$scope.products_list = [];
// Get the current URL and then regex out everything except numbers - ie the entry id
$.url().attr('anchor').replace(/\D/g,'');
$scope.products_list = api_get_channel_entries_products.query();
}
Angular works as following:
Forgiving: expression evaluation is forgiving to undefined and null, unlike in JavaScript, >where trying to evaluate undefined properties can generate ReferenceError or TypeError.
http://code.angularjs.org/1.2.9/docs/guide/expression
so you only need to write:
<title>{{products_list[0].tool_type}}</title>
if there is a zero element the title will be the tool_type, if not, there is no title.
Assuming you want to select a random object from the list to use something like this should work:
$scope.product-tool_type = products_list[Math.floor(Math.random()*products_list.length)].tool_type
Then to display the result just use
<h1>{{product-tool_type}}</h1>
Or alternatively:
<h1>{{products_list[Math.floor(Math.random()*products_list.length)].tool_type}}</h1>
I am using extjs 4.1.1a for developing some application.
I had a form consisting of two combo-boxes and an item-selector.
Based on the value selected in first combo-box , the itemselector will load its data from database. This is working fine.
My problem is, if i reselect the first combo-box the new data will be displayed in itemselector along with previous data displayed in itemseletor .That is previous data displayed in itemselector will remain there itself.
for example: name "test1" consists of ids 801,2088,5000. on selecting test1 in firstcombobox itemselector must show output as below.
and if "test2" consists of ids 6090,5040. on selecting test2 in firstcombobox itemselector must show output as below.
problem is. for first time if i select "test1" from firstcombobox , output will come as expected. if i reselect "test2" from firstcombobox , output will come as below.
as you can see, previous data displayed (marked in red rectagle) remains there itself with new data displayed (marked with green rectangle).
I want for every reselection of first combobox, previously displayed data in itemselector to be erased before printing new data on itemselector.
How can I reset the itemselector for every reselection of first combobox?
You should remove all items from the store of the itemselector by the removeAll command. After that you should load the store of the itemselector.
itemselector.store.removeAll();
itemselector.store.load();
Any solutions above solve my problem.
i found solution from Sencha Forum.
https://www.sencha.com/forum/showthread.php?142276-closed-Ext-JS-4.0.2a-itemselector-not-reloading-the-store
in the itemselector.js file, change the line marked below.
populateFromStore: function(store) {
var fromStore = this.fromField.store;
// Flag set when the fromStore has been loaded
this.fromStorePopulated = true;
// THIS LINE BELOW MUST BE CHANGED!!!!!!!!!!!!
fromStore.loadData(store.getRange()); //fromStore.add(store.getRange());
// setValue waits for the from Store to be loaded
fromStore.fireEvent('load', fromStore);
},
You need to insert...
this.reset();
at the head of the function that is inserting the data.
As an example...
Ext.override( Ext.ux.ItemSelector, {
setValue: function(val) {
this.reset();
if (!val) return;
val = val instanceof Array ? val : val.split(this.delimiter);
var rec, i, id;
for (i = 0; i < val.length; i++) {
var vf = this.fromMultiselect.valueField;
id = val[i];
idx = this.toMultiselect.view.store.findBy(function(record){
return record.data[vf] == id;
});
if (idx != -1) continue;
idx = this.fromMultiselect.view.store.findBy(function(record){
return record.data[vf] == id;
});
rec = this.fromMultiselect.view.store.getAt(idx);
if (rec) {
this.toMultiselect.view.store.add(rec);
this.fromMultiselect.view.store.remove(rec);
}
}
}
});
are u got it?
when u select that combobox frist stoe of item selector is null after store load with ur pass the para meters
for example
store.load(null),
store.proxey.url='jso.php?id='+combobox.getrawvalue(),
store.load();
like that so when ur select a value in ur combobox that time ur used a listeners to ur combobox in that listners ur used above code , select ur some value in combobox that time frist store is get null after ur pass some values to json.php then store load with responce so that time old data is remove and new data load in that store
if u post ur code i will give correct code
I ran into the same issue with ExtJS 4.2.1. I got it to work by calling reload() on the data store and then setValue() with an empty string on the item selector in the data store's reload() callback.
Ext.create("Ext.form.field.ComboBox", {
// Other properties removed for brevity
listeners: {
change: function(field, newValue, oldValue, eOpts) {
Ext.getStore("ExampleStore").reload({
callback: function() {
Ext.getCmp("ExampleItemSelector").setValue("");
}
});
}
}
});
Ext.create("Ext.data.Store", {
storeId: "ExampleStore",
// Other properties removed for brevity
});
Ext.create("Ext.form.FormPanel", {
// Other properties removed for brevity
items:[{
xtype: "itemselector",
id: "ExampleItemSelector",
// Other properties removed for brevity
}]
});
For any folks that are curious, I'm fairly convinced there's a bug in the item selector's populateFromStore() function. When the function is called, it blindly adds all of the values from the bound store (store) to the internal store (fromStore). I suspect there should be a call to fromStore.removeAll() prior to the call to fromStore.add(). Here's the relevant code from ItemSelector.js.
populateFromStore: function(store) {
var fromStore = this.fromField.store;
// Flag set when the fromStore has been loaded
this.fromStorePopulated = true;
fromStore.add(store.getRange());
// setValue waits for the from Store to be loaded
fromStore.fireEvent('load', fromStore);
},
EDIT 12/18/2013
If you've configured any callback events on the item selector (e.g. change), you may want to disable the events temporarily when you call setValue(""). For example:
var selector = Ext.getCmp("ExampleItemSelector");
selector.suspendEvents();
selector.setValue("");
selector.resumeEvents();
I had the same problem and finally I decided to modify the extjs source code, not considering it a big issue as extjs itself its saying in the start of the file
Note that this control will most likely remain as an example, and not as a core Ext form
control. However, the API will be changing in a future release and so should not yet be
treated as a final, stable API at this time.
Based on that, as jstricker guessed (and sadly I didn't read and took me a while to arrive to the same conclusion), adding fromStore.removeAll() before fromStore.add() solves the problem.
Outside of the problem (but I think it can be interesting as well), additionally, I also added listConfig: me.listConfig in the MultiSelect configuration (inside createList), that way it's possible to format each item additional options (such as images, etc.) setting in the 'itemselector' the option listConfig as it's explained in the (irrealistic) documentation.
Need to reset the store used in ItemSelector that can be done by setting Empty object like below. Also need to call clearValue() method of ItemSelector component.
store.setData({});
ItemSelectorComponent.clearValue();
