I have a web application with multiple Selectize objects initialized on the page. I'm trying to have each instance load a default value based on the query string when the page loads, where ?<obj.name>=<KeywordID>. All URL parameters have already been serialized are are a dictionary call that.urlParams.
I know there are other ways to initializing Selectize with a default value I could try; but, I'm curious why calling setValue inside onInitialize isn't working for me because I'm getting any error messages when I run this code.
I'm bundling all this JavaScript with Browserify, but I don't think that's contributing to this problem.
In terms of debugging, I've tried logging this to the console inside onInititalize and found that setValue is up one level in the Function.prototype property, the options property is full of data from load, the key for those objects inside options corresponds to the KeywordID. But when I log getValue(val) to the console, I get an empty string. Is there a way to make this work or am I ignoring something about Selectize or JavaScript?
module.exports = function() {
var that = this;
...
this.selectize = $(this).container.selectize({
valueField: 'KeywordID', // an integer value
create: false,
labelField: 'Name',
searchField: 'Name',
preload: true,
allowEmptyOptions: true,
closeAfterSelect: true,
maxItems: 1,
render: {
option: function(item) {
return that.template(item);
},
},
onInitialize: function() {
var val = parseInt(that.urlParams[that.name], 10); // e.g. 5
this.setValue(val);
},
load: function(query, callback) {
$.ajax({
url: that.url,
type: 'GET',
error: callback,
success: callback
})
}
});
};
...
After sprinkling in some console.logs into Selectize.js, I found that the ajax data hadn't been imported, when the initialize event was triggered. I ended up finding a solution using jQuery.when() to make setValue fire after the data had been loaded, but I still wish I could find a one-function-does-one-thing solution.
module.exports = function() {
var that = this;
...
this.selectize = $(this).container.selectize({
valueField: 'KeywordID', // an integer value
create: false,
labelField: 'Name',
searchField: 'Name',
preload: true,
allowEmptyOptions: true,
closeAfterSelect: true,
maxItems: 1,
render: {
option: function(item) {
return that.template(item);
},
},
load: function(query, callback) {
var self = this;
$.when( $.ajax({
url: that.url,
type: 'GET',
error: callback,
success: callback
}) ).then(function() {
var val = parseInt(that.urlParams[that.name], 10); // e.g. 5
self.setValue(val);
});
}
});
};
...
You just need to add the option before setting it as the value, as this line in addItem will be checking for it:
if (!self.options.hasOwnProperty(value)) return;
inside onInitialize you would do:
var val = that.urlParams[that.name]; //It might work with parseInt, I haven't used integers in selectize options though, only strings.
var opt = {id:val, text:val};
self.addOption(opt);
self.setValue(opt.id);
Instead of using onInitialize you could add a load trigger to the selectize. This will fire after the load has finished and will execute setValue() as expected.
var $select = $(this).container.selectize({
// ...
load: function(query, callback) {
// ...
}
});
var selectize = $select[0].selectize;
selectize.on('load', function(options) {
// ...
selectize.setValue(val);
});
Note that for this you first have to get the selectize instanze ($select[0].selectize).
in my case it need refresh i just added another command beside it
$select[0].selectize.setValue(opt);
i added this
$select[0].selectize.options[opt].selected = true;
and changes applied
but i dont know why?
You can initialize each selectize' selected value by setting the items property. Fetch the value from your querystring then add it as an item of the items property value:
const selectedValue = getQueryStringValue('name') //set your query string value here
$('#sel').selectize({
valueField: 'id',
labelField: 'title',
preload: true,
options: [
{ id: 0, title: 'Item 1' },
{ id: 1, title: 'Item 2' },
],
items: [ selectedValue ],
});
Since it accepts array, you can set multiple selected items

I've just defined a combobox. Firstly it loads a countrylist and when select a value it's fire a change event which doing a ajax query to DB within searching service;
The thing; this configuration works pretty well when I click and open combobox items. But when I'm typing to combobox's field it's fires listener's store.load and because of none of country selected yet, the search query url gives not found errors of course.
{
xtype: 'countrycombo',
itemId: 'countryName',
name:'country',
afterLabelTextTpl: MyApp.Globals.required,
allowBlank: false,
flex: 1,
// forceSelection: false,
// typeAhead: true,
// typeAheadDelay: 50,
store: {
proxy: {
type: 'ajax',
// isSynchronous: true,
url: MyApp.Globals.getUrl() + '/country/list?limit=250',
// timeout: 300000,
reader: {
type: 'json',
rootProperty: 'data'
}
},
pageSize: 0,
sorters: 'description',
autoLoad: true
}
,
listeners: {
change: function (combo, countryId) {
var cityStore = Ext.getStore('cityCombo');
cityStore.getProxy()
.setUrl(MyAppp.Globals.getUrl() + '/city/view/search?query=countryid:'+ countryId);
// Ext.defer(cityStore.load, 100);
cityStore.load();
}
}
},
I've tried several things as you see in code above to set a delay/timeout for load during typing to combobox text field; Ext.defer, timeoutconfig on proxy, typeAhead config on combo but none of them worked!
I thought that Ext.defer is the best solution but it gives this error:
Uncaught TypeError: me.getAsynchronousLoad is not a function at load (ProxyStore.js?_dc=15169)
How can I set a delay/timeout to combobox to fires load function?
Instead of Ext.defer(cityStore.load, 100);
try using this :
Ext.defer(function(){
cityStore.load
}, 300);
If this doest work, try increasing your delay
or you can put a logic before loading
like this :
if(countryId.length == 5){
cityStore.load
}
This will ensure that you Entered the right values before loading
Hope this helps, and Goodluck on your project
well.. I've tried to implement #Leroy's advice but somehow Ext.defer did not fire cityStore.load. So I keep examine similar situations on google and found Ext.util.DelayedTask
So configured the listerens's change to this and it's works pretty well;
listeners: {
change: function (combo, countryId) {
var alert = new Ext.util.DelayedTask(function () {
Ext.Msg.alert('Info!', 'Please select a country');
});
var cityStore = Ext.getStore('cityCombo');
cityStore.getProxy().setUrl(MyApp.Globals.getUrl() + '/city/view/search?query=countryid:'+ countryId);
if (typeof countryId === 'number') {
cityStore.load();
} else {
alert.delay(8000);
}
}
}
I have a property grid :
periods.each(function(record){
var tempPropGrid = me.getView().add(
{
xtype:'propertygrid',
width: 80,
header: false,
title: 'prop grid',
//for some reason the headers are not hiding, we may need to deal with this using CSS
//hideHeaders: true,
enableColumnResize: false,
sortableColumns: false,
nameColumnWidth: 1,
source: record.data,
sourceConfig: {
periodScrumMaster: {
editor: Ext.create('Ext.form.ComboBox', {
tdCls: 'red',
store: team,
queryMode: 'local',
displayField: 'personName',
valueField: 'personName',
listeners: {
'expand' : function(combo) {
var gridvalues = this.up('propertygrid').getSource();
combo.getStore().clearFilter(true);
combo.getStore().addFilter({property: 'teamName', value: teamName});
combo.getStore().addFilter({property: 'periodName', value: gridvalues.periodName});
var totalFTE = team.count();
console.log(totalFTE);
var teamStore = Ext.getStore('personPeriods');
console.log('store');
console.log(teamStore);
},
}}),
displayName: 'Scrum Master'
},
},
That has a render listener:
beforerender: function(){
debugger;
var gridValues = this.getSource();
// console.log(record);
//debugger;
// filter periods for this period only
periods.filterBy(function(record,id){
if(record.get("periodName") === gridValues.periodName){
return true;
}});
// filter teamMembers for this period and team
var view = this.up();
var vm = view.getViewModel();
var store = vm.getStore('teamMembers');
store.filterBy(function(record,id){
if(record.get("periodName") === gridValues.periodName) {
return true;
}});
//store.clearFilter(true);
store.addFilter({property: 'teamName', value: teamName});
// get FTEs assigned to this team in this period by counting records
var resourcedFtes = store.count();
// Here I check the record in the periods store to make sure the data matches up with how many resourcedFte there is an update it if required
// This is super bad and will need to refactor
periods.each(function(record,idx){
var value = record.get('resourcedFte');
if(value != resourcedFtes){
record.set('resourcedFte',resourcedFtes);
record.commit();
vm.data.parentController.saveParent();
}});
// Need to call save parent so that the record is updated when we update it above
//Clear everything so that we can start fresh next period
store.clearFilter(true);
//periods.clearFilter(true);
Basically there is some logic to check if the data is correct/up to date and if its not it updates it. This works fine, but the data is not then loaded into the grid. I have to refresh after rendering the grid for it to load correctly.
Is there a way I can call a refresh or reload method on the property grid to load the data again inside an if statement?
If I understand your question, I would suggest you to programm the store proxy so that it returns the whole changed record.
Is your store parametered with autoLoad enabled?
(sorry I can't (yet) comment)
I am using dgrid and i am attempting to set the dataStore externally. When the page loads i call aliasTicket.load() to create the grid. At the time the grid is loading the datasource is null. When a query is executed the setAliasSource(aliasData); is set.
There are no errors however the grid is still empty. The aliasStore is being updated with data however it isn't being reflected on the grid even after the grid is refreshed. How can i get the data reflected in the grid after the query?
Javascript Object
var aliasTicket = (function (){
var aliasData = [];

Setting Data Store Data
aliasData = [{.....},

You are setting 'this.Store' to an object array, not a real 'dojo store' object. Following your code I can not see where you actually use 'this.Store'. Inside the grid code I do see a local variable named 'Store'.
So I'm not sure if I'm following your code example here but, you should 'set' the store of the grid and then refresh it. Something like this.
setAliasSource: function (data){
console.log(data);
this.Store = data;
dijit.byId('aliasNameGrid').set("store",new dojo.store.Observable(new dojo.store.Memory({ data: data,idProperty: "id"}));
dijit.byId('aliasNameGrid').refresh();
},
Problem
I have a text input that I have selectized as tags which works fine for querying remote data, I can search and even create new items using it and that all works OK.
Using selectize:
var $select = $('.authorsearch').selectize({
valueField: 'AuthorId',
labelField: 'AuthorName',
searchField: ['AuthorName'],
maxOptions: 10,
create: function (input, callback) {
$.ajax({
url: '/Author/AjaxCreate',
data: { 'AuthorName': input },
type: 'POST',
dataType: 'json',
success: function (response) {
return callback(response);
}
});
},
render: {
option: function (item, escape) {
return '<div>' + escape(item.AuthorName) + '</div>';
}
},
load: function (query, callback) {
if (!query.length) return callback();
$.ajax({
url: '/Author/SearchAuthorsByName/' + query,
type: 'POST',
dataType: 'json',
data: {
maxresults: 10
},
error: function () {
callback();
},
success: function (res) {
callback(res);
}
});
}
});
The text box:
<input class="authorsearch" id="Authors" name="Authors" type="text" value="" />
Examples:
Then when I select one (in this case 'apple') it comes up in a badge as you'd expect, and the underlying value of the textbox is a comma separated list of the values of these items.
Current Output
The problem is when I load a page and want values retrieved from the database to be displayed in the selectized text input as tags, it only loads the values and I can see no way of displaying the displayname instead.
<input class="authorsearch" id="Authors" name="Authors" type="text" value="1,3,4" />
Desired Ouput
I have tried all sorts of values for the inputs value field to have it load the items as showing their displayname and not their values. Below is an example of a single object being returned as JSON, being able to load a JSON array of these as selectized tags would be ideal.
[{"AuthorId":1,"AuthorName":"Test Author"},
{"AuthorId":3,"AuthorName":"Apple"},
{"AuthorId":4,"AuthorName":"Test Author 2"}]
How can I go about this? Do I need to form the value of the text box a particular way, or do I need to load my existing values using some javascript?
Thanks to your answer and based on your onInitialize() approach I ended up with a similar solution. In my case I just needed to translate one value, thus I was able to store the id and label as data attributes in the input field.
<input type="text" data-actual-value="1213" data-init-label="Label for 1213 item">
Then on initialization:
onInitialize: function() {
var actualValue = this.$input.data('actual-value');
if (actualValue){
this.addOption({id: actualValue, value: this.$input.data('init-label')});
this.setValue(actualValue);
this.blur();
}
}
According to these options:
$('input').selectize({
valueField: 'id',
labelField: 'value',
searchField: 'value',
create: false,
maxItems: 1,
preload: true,
// I had to initialize options in order to addOption to work properly
// although I'm loading the data remotely
options: [],
load: ... ,
render: ...,
onInitialize: ....
});
I know this does not answer your question but wanted to share just in case this could help someone.
I ended up using the onInitialize callback to load the JSON values stored in a data-* field. You can see it in action here in this jsfiddle.
<input class="authorsearch" id="Authors" name="Authors" type="text" value=""
data-selectize-value='[{"AuthorId":1,"AuthorName":"Test"},{"AuthorId":2,"AuthorName":"Test2"}]'/>
Basically it parses the data-selectize-value value and then adds the option(s) to the selectize then adds the items themselves.
onInitialize: function() {
var existingOptions = JSON.parse(this.$input.attr('data-selectize-value'));
var self = this;
if(Object.prototype.toString.call( existingOptions ) === "[object Array]") {
existingOptions.forEach( function (existingOption) {
self.addOption(existingOption);
self.addItem(existingOption[self.settings.valueField]);
});
}
else if (typeof existingOptions === 'object') {
self.addOption(existingOptions);
self.addItem(existingOptions[self.settings.valueField]);
}
}
My solution does presume my JSON object is formed correctly, and that it's either a single object or an object Array, so it may or may not be appropriate for someone elses needs.
So it parses:
[{"AuthorId":1,"AuthorName":"Test"},
{"AuthorId":2,"AuthorName":"Test2"}]
To:
Based of course on my selectize settings in my original post above.
Even simpler on new version of selectize using items attribute. Basically to set a selected item you need to have it first in the options. But if you use remote data like me, the options are empty so you need to add it to both places.
$('select').selectize({
valueField: 'id',
labelField: 'name',
options:[{id:'123',name:'hello'}],
items: ['123'],
...
This is working for me and took me a while to figure it out... so just sharing
I have a problem creating ng-grids dynamically:
The next function loops through each element of $scope.dataSparqlResponses (each element is an array of data) and put the value of the iteration in $scope.dataSparqlAux. And $scope.dataSparqlAux is the variable used in the grids (data input). The problem is that in each iteration this variable ($scope.dataSparqlAux) is reassigned, so in the template I can only see the last grid with data.
**controller.js**
$scope.crearGrids = function() {
angular.forEach($scope.dataSparqlResponses, function(elem) {
$scope.dataSparqlAux = elem.data;
$scope.dataGrids.push({grid: {
data: 'dataSparqlAux',
enablePinning: false,
showFooter: true,
selectedItems: [],
i18n: 'es',
showSelectionCheckbox: true,
afterSelectionChange: function() {
console.log(this);
},
columnDefs: [{field: elem.nombre + '.value', displayName: elem.nombre, cellTemplate: templateWithTooltip}]
}});
console.log($scope.dataGrids);
});
};
**template.html**
<div data-get-width data-num-elementos="{{dataGrids.length}}" >
<div ng-repeat="dataGrid in dataGrids">
<div class="tabla_det" ng-grid="dataGrid.grid"></div>
</div>
</div>
is possible to do something like this?
$scope.dataGrids.push({grid: {
**data: 'dataSparqlResponses[cont]',**
enablePinning: false,
showFooter: true,
selectedItems: [],
i18n: 'es',
showSelectionCheckbox: true,
afterSelectionChange: function() {
console.log(this);
},
columnDefs: [{field: elem.nombre + '.value', displayName: elem.nombre, cellTemplate: templateWithTooltip}]
}});
console.log($scope.dataGrids);
How can I fix this to create grids and display information dynamically?
Regards and thanks for your time.
EDIT: here a plunker with the problem http://plnkr.co/edit/zYtuMW4TKW053YoDY0kg?p=preview
I've shared an answer on github about your issue.
Basically, data is referencing a variable, you're not storing it.
What you can do is reference a new variable on every loop, as shown in the jsbin.
Declare an index :
var index = 0;
You declare your string with the index of the sub-document :
var dirtyConcat = 'dataSparqlResponses['+index+'].data';
Don't forget to increment the index :
++index;
Then, you reference it.
data: dirtyConcat,
