Is it possible to configure an Extjs combobox where the remote queryMode utilises a jsonp request?
Yes just make your store use a http://docs.sencha.com/ext-js/4-1/#!/api/Ext.data.proxy.JsonP
Ext.define('User', {
extend: 'Ext.data.Model',
fields: ['id', 'name', 'email']
});
var store = Ext.create('Ext.data.Store', {
model: 'User',
proxy: {
type: 'jsonp',
url : 'http://domainB.com/users'
}
});
Ext.create('Ext.form.ComboBox', {
fieldLabel: 'Choose User',
store: store,
queryMode: 'remote',
displayField: 'email',
valueField: 'id',
renderTo: Ext.getBody()
});
The following script tag will be injected
<script src="http://domainB.com/users?callback=callback1"></script>

I need to populate combobox with JSON data. This is my store:
Ext.define('Test.store.GetShopSurvey', {
extend: 'Ext.data.Store',
alias: 'store.GetShopSurvey',
model: 'Test.model.GetShopSurvey',
storeId: 'GetShopSurvey',
proxy: {
type: 'ajax',
url: 'http://localhost/webcontent/CShopSurveyWebApplet&SubFunc=GetShopSurvey',
reader: {
type: 'json',
}
}
});
And my view:
Ext.define('Test.view.main.Announcement',
{
extend: 'Ext.panel.Panel',
requires: [
'Test.view.main.AnnouncementController',
'Test.view.main.AnnouncementModel',
'Test.store.Personnel'
],
store: {
type: 'GetShopSurvey'
},
And one of the items is:
{
xtype: 'combo',
fieldLabel: 'Range',
name: 'Range1',
store: , //here I need store to load. For example json value is {"range": 70}
displayField: 'range',
autoSelect: true,
forceSelection: true,
disabled: true
},
I added fields to model with name and type of data. However, I don't know how to get data from JSON and parse it in combobox. I commented place where I need to put that value btw.
Have you tried :
{
xtype: 'combo',
fieldLabel: 'Range',
name: 'Range1',
store: 'GetShopSurvey',
queryMode: 'local',
displayField: 'range',
valueField: 'range',
autoSelect: true,
forceSelection: true,
disabled: true
}
If this doesn't work can you give me more information like toolkit and extjs version please
You should create an store instance and then use it.Moreover, set its autoLoad config to true value.
try loadRawData method
var jsonData = {'range':500};
combo.getStore().loadRawData(jsonData);
I am using Extjs 4.1, tried to load data for Combobox, but doesn't work. I have strong doubt about hte json reader root / record.
the data model and store are defined ,
Ext.define('tagModel', {
extend: 'Ext.data.Model',
fields: [
{name: 'id', type: 'string'},
{name: 'name', type: 'string'}
]
});
var tagStore = new Ext.data.Store({
model: 'tagModel',
proxy: {
type: 'ajax',
url: '/ExtjsWebApp/webresources/question/loadTags',
reader: {
type: 'json',
record : 'rtnList'
}
},
listeners: {
load: function(store, records, options){
alert("success " +records.length);
}
},
autoLoad: true
});
the ComboBox is defined as this,
{
itemId: 'search_tag_fld',
fieldLabel: 'Tag',
xtype: 'combobox',
displayField: 'name',
valueField: 'id',
store: tagStore,
queryMode: 'remote',
multiSelect: true,
anchor: '100%',
labelHeight: 300
}
I am sure that the restful webservice will return data as this
{"rtnList":[{"id":1,"name":"Java","active":"true"},{"id":2,"name":"J2EE","active":"true"},{"id":3,"name":"JMS","active":"true"},{"id":4,"name":"Design","active":"true"},{"id":5,"name":"SOA","active":"true"}],"successMsg":"success","errorMsg":"","time":"09/21/2013 18:34:55","sessionId":null,"userId":null}
In your reader, change "record" to "root". Here's a fiddle that shows that your current setup will work just fine: https://fiddle.sencha.com/#fiddle/km
I have a combobox in a form:
{
xtype: 'combobox',
fieldLabel: 'Jurisdictions',
name: 'jurisdiction_id',
id: 'ComboboxJurisdictions',
store: Ext.create('App.store.Jurisdictions'),
queryMode: 'local',
editable: false,
displayField: 'name',
valueField: 'id',
}
Data is:
1 => Administrator
2 => User
3 => Guest
Now, if I don't touch anything when editing a user, on my server for my combobox I get "Administrator" (displayField), but when I change something in combobox I get the "id" (valueField). I really just want "id" in both cases. I was reading about hiddenName? Is that the case?
If you need any more code, feel free to ask. :)
Thank you!
EDIT (more code)
1.) There is no default value.
Here is the whole view code:
Ext.define('App.view.Suits.Update', {
extend: 'Ext.window.Window',
title: 'Suits',
width: 250,
id: 'UpdateWindowSuits',
defaultType: 'textfield',
items: [{
xtype: 'UpdateFormSuits'
}],
buttons: [
{ text: 'Save', id: 'submitUpdateFormButtonSuits'},
{ text: 'Cancel', id: 'cancelUpdateFormButtonSuits'},
]
});
Ext.define('App.view.Suits.UpdateForm', {
extend: 'Ext.form.Panel',
alias: 'widget.UpdateFormSuits',
layout: 'form',
id: 'UpdateFormSuits',
bodyPadding: 5,
defaultType: 'textfield',
items: [{
fieldLabel: 'Id',
name: 'id',
hidden: true
},{
fieldLabel: 'Name',
name: 'name',
allowBlank: false,
},{
fieldLabel: 'Status',
name: 'status',
allowBlank: false
},{
xtype: 'combobox',
fieldLabel: 'Priority',
name: 'suit_priority_id',
id: 'ComboboxSuitPriorities',
store: Ext.create('App.store.SuitPriorities'),
editable: false,
displayField: 'name',
hiddenName: 'id',
valueField: 'id'
},{
xtype: 'combobox',
fieldLabel: 'Jurisdictions',
name: 'jurisdiction_id',
id: 'ComboboxJurisdictions',
store: Ext.create('App.store.Jurisdictions'),
queryMode: 'local',
editable: false,
displayField: 'name',
valueField: 'id',
}],
});
Here is the store:
Ext.define('App.store.SuitPriorities', {
extend: 'Ext.data.Store',
// Where is the Model.
model: 'App.model.SuitPriority',
// "id" of the Store.
storeId: 'SuitPriorities',
// Autoload all data on creation.
autoLoad: true,
// Number of records in one page (for pagination).
pagesize: 20,
// Proxy for CRUD.
proxy: {
// Type of request.
type: 'ajax',
// API for CRUD.
api: {
create : 'php/suitpriorities/update',
read : 'php/suitpriorities/read',
update : 'php/suitpriorities/update',
destroy : 'php/suitpriorities/delete'
},
// Type of methods.
actionMethods: {
create : 'POST',
read : 'POST',
update : 'POST',
destroy : 'POST'
},
// Reader.
reader: {
// Which type will the reader read.
type: 'json',
// Root of the data.
root: 'suitpriorities',
rootProperty: 'data',
// One record.
record: 'SuitPriority',
// Message and success property.
successProperty: 'success',
messageProperty: 'message'
},
// Writer (when sending data).
writer: {
type: 'json',
writeAllFields: true,
root: 'data',
encode: true
},
});
As I sad, the store is getting all the data because it's already loaded when I press the combobox. It's a simple JSON with 'id' and 'name' properties.
EDIT2: I've tried this for my Jurisdictions because I wasn't getting the right data selected in combobox. This is inside my controller.
onJurisdictionComboRender: function(combobox, eOpts){
// Getting the selected row.
var record = this.grid.getSelectionModel().getSelection()[0];
// Selected jurisdiction.
var jurisdiction = record.data.jurisdiction_id;
// Select it in combobox.
combobox.select(jurisdiction);
}
That doesn't make sense... If you read out the combo the correct way, meaning let either the form doing the work or calling getSubmitValue() on your own the combo would always returning the valueField. hiddenName is used for other purposes. Please take a look at the console of this JSFiddle and recheck how you fetch the combo value.
Here's the working demo-code
// The data store containing the list of states
var roles = Ext.create('Ext.data.Store', {
fields: ['id', 'name'],
data : [
{"id":1, "name":"Administrator"},
{"id":2, "name":"User"},
{"id":3, "name":"Guest"}
//...
]
});
// Create the combo box, attached to the states data store
var combo = Ext.create('Ext.form.ComboBox', {
fieldLabel: 'Choose Role',
store: roles,
queryMode: 'local',
editable: false,
displayField: 'name',
valueField: 'id',
renderTo: Ext.getBody()
});
combo.on('select', function(cb){ console.log(cb.getSubmitValue()); })
+1 for everyone for helping but the problems was here:
In my store I've put autoLoad: false and inside my combobox I've put store.load() manually and it works perfectly.
Thank you all! :)
I am new to the extjs and try to make following codes work:
I tried as you suggested, still no luck:
var bookmarks=[];
bookmarks[0] ={id:'111111111', target:'target', title:'title', category:'category', created:'created'};
bookmarks[1] ={id:'22222222222', target:'target', title:'title22222222', category:'category', created:'created'};
localStorage['myapp-bookmarks']=JSON.stringify(bookmarks);
Ext.define("BookMark", {
extend: 'Ext.data.Model',
idProperty: "id",
fields: ['id','target','title','category','created']
});
var bookmarkStore = Ext.create("Ext.data.Store", {
model: "BookMark",
autoLoad: true,
storeId: 'bookmarks',
proxy: {
type: 'localstorage',
id : 'myapp-bookmarks'
}
});
// Create the combo box, attached to the above store
Ext.create('Ext.form.ComboBox', {
fieldLabel: 'Choose State',
store: bookmarkStore,
queryMode: 'local',
displayField: 'title',
valueField: 'id',
renderTo: Ext.getBody()
});
But it won't populate the list for me. Any idea?
When I am trying to fetch data from the Store in the Combo Box,I am getiing output as--- [object Object]!!! but the value of the object is not coming!! Can any body tell me what is the problem or what should be the solution for this???
In Extjs 4.0:
Create data model
Ext.define('Bond', {
extend: 'Ext.data.Model',
idProperty: 'userid',
fields: [
{
name :'industryGroupsreName',
type:'string'
},
]
});
Create store
var industry=new Ext.data.Store(
{
model:'Bond',
proxy:
{
type: 'ajax',
url: 'industry.html',
reader: {
type: 'json'
}
}
});
industry.load();
Apply bellow code to your combo box
new Ext.create('Ext.form.ComboBox',
{
fieldLabel: 'Industry Group Name',
store: industry,
id: "industrygroup",
name: "industrygroup",
allowBlank: false,
hiddenName : 'industrygroup',
width:300,
queryMode: 'local',
displayField: 'industryGroupsreName',
valueField: 'industryGroupsreName'
}),
