Search2 - Ajax results with no search - jquery-select2

I'm using ajax to pull in data from a php file (which returns json).
I'm wondering, can you have results pulled from Ajax and loads on click without having to search? so essentially you click the field, it drops down with all the elements from Ajax. Couldn't find in the documentation.
Code:
jQuery('.producttypesajax').select2({
allowClear: true,
placeholder: {
id: '',
text: 'Search by Product Type'
},
ajax: {
url: base + '/appProductTypeSearch.php',
dataType: 'json',
delay: 250,
data: function( params ) {
return {
q: params.term // search term
};
},
processResults: function( data) {
return {
results: data
};
},
cache: true
},
minimumInputLength: 1
});
jQuery('.producttypesajax').on('select2:select', function (e) {
var data = e.params.data;
});
https://select2.org/data-sources/ajax

I believe there's no native solution for this, but I managed to do it somehow.
Since Select2 accepts Arrays as a data source, you can make an Ajax request returning your Json object and use it as an "Array".
Sample code:
$.ajax({
url: url,
type: 'get',
dataType: 'json',
success: function (jsonObject){
$('#mySelect').select2({ data: jsonObject });
}
});
It worked for me. Hope it helps.

What data structure is select2 expecting from the server and how should it be handled?

What data structure is select2 (v4.0.3) expecting from the server and how should it be handled?
The question is asked on the official FAQ here, but there is no answer.
I have tried several variations of data structure, but based on this tutorial and this jsFiddle, have assumed what should be returned from the server is a list/array of objects/dicts, eg:
matches = [{"id":"1", "tag":"Python"},{"id":"2", "tag":"Javascript"},{"id":"3", "tag":"MongoDB"}]
I have tried this format with the following Javascript:
$("#my_select").select2({
ajax: {
url: "/tag_search",
dataType: 'json',
delay: 250,
data: function (params) {
return {
q: params.term // search term
};
},
processResults: function (data) {
return {
results: data.matches
};
},
cache: true
},
minimumInputLength: 2,
tags: true,
tokenSeparators: [",", " "],
maximumSelectionLength: 5
});
Firebug results for search on Py:
The search area just displays this:
I am expecting all matches to be showing in the dropdown below the search area.
Solution that worked for me:
Rename json key (it has to be text), so server response is:
[{"text": "Python", "id": 1}]
(after coming across this document).
I also just returned the list itself from the server, rather than making the list a dict value.
Javascript
$("#my_select").select2({
ajax: {
url: "/tag_search",
dataType: 'json',
delay: 250,
data: function (params) {
return {
q: params.term // search term
};
},
processResults: function (data) {
return {
results: data
};
},
cache: true
},
minimumInputLength: 2,
tags: true,
tokenSeparators: [",", " "],
maximumSelectionLength: 5
});

Making AJAX call to MVC API

I am trying to make an API call with ajax:
svc.authenticateAdmin = function (id, code) {
$.ajax({
url: 'api/event/authenticate',
data: { 'id': id, 'code': code },
datatype: 'json',
contentType: 'application/json',
type: 'GET',
success: function (data) {
App.eventBus.publish('authenticationComplete', data);
}
});
};
The method in the API Controller:
[ActionName("All")]
public bool Authenticate(int id, string code)
{
var repo = new MongoRepository<Event>(_connectionString);
var entry = repo.FirstOrDefault(e => e.Id == id);
return entry.AdminPassword == code;
}
But I am getting a 404 error: urlstuff/api/event/authenticate?id=123&code=abc 404 (Not Found)
I have copied the implementation from a number of known working calls (that I did not write). That look like:
svc.getEventFromCode = function (code) {
$.ajax({
url: '/api/event/',
data: { 'code': code },
dataType: 'json',
type: 'GET',
success: function (data) {
App.eventBus.publish('loadedEvent', data);
App.eventBus.publish('errorEventCodeExists');
},
error: function () {
App.eventBus.publish('eventNotFound', code);
}
});
};
and
svc.getEventPage = function (pageNumber) {
$.ajax({
url: '/api/event/page/',
data: { 'pageNumber': pageNumber },
dataType: "json",
contentType: "application/json",
type: 'GET',
success: function (data) {
App.eventBus.publish('loadedNextEventsPage', data);
}
});
};
But neither has to pass in 2 parameters to the API. I'm guessing it's something really minor :/
Your action name is called "Authenticate", but you have included the following which will rename the action:
[ActionName("All")]
This makes the URL
/api/event/all
The problem lies in your url.
Apparently, ajax interpret / at the start of the url to be root
When the application is deployed on serverserver, its URL is something like http://localhost:8080/AppName/
with api/event/page/, ajax resolve the URL to http://localhost:8080/AppName/api/event/page/ or an url relative to your current directory.
However, with /api/event/page/, the URL is resolved to http://localhost:8080/api/event/page/
Hope it helped.

JQueryAutoComplete Not showing results

I am trying to bind the text box and the JQuery AutoComplete feature. When I checked the Firebug AJAX Request & Response it returns like the following. But the textbox is not showing any items. Could you please advise me, what I am doing wrong? Thanks.
Here is my coding:
$("#<%= TextBox1.ClientID %>").autocomplete({
source: function (request, response) {
$.ajax({
url: "/contractors/web_services/wsSM.asmx/SearchDrugs",
type: "POST",
dataType: "json",
data: {
'LocationID': "10543",
'Search': request.term
},
success: function (data) {
response($.map(data.d, function (item) {
return {
value: item.FullDrugName,
id: item.DrugID
}
}))
}
});
},
delay: 1,
minLength: 2,
select: function (event, ui) {
alert(ui.item.id);
}
});
DataType property is representing the type of data that you're expecting back from the server.
you define data type as json but server returns you a xml output. You should change your DataType property to xml
In addition to #fealin's answer, you're going to need to change the way you process the xml response. It doesn't look like you have a d property on the return data, and you also need to look for the correct nodes in the XML structure and pull out their text to build the response array that you return to the widget.
Based on the XML you've provided, it might look something like this:
$("#<%= TextBox1.ClientID %>").autocomplete({
source: function (request, response) {
$.ajax({
url: "/contractors/web_services/wsSM.asmx/SearchDrugs",
type: "POST",
dataType: "json",
data: {
'LocationID': "10543",
'Search': request.term
},
success: function (data) {
response($(data).find("Drug").map(function (_, el) {
var $el = $(el);
return {
label: $el.find("FullDrugName").text(),
value: $el.find("DrugID").text()
};
}));
});
},
delay: 1,
minLength: 2,
select: function (event, ui) {
alert(ui.item.id);
}
});
Here's an example that's just using the XML string (without an AJAX request): http://jsfiddle.net/J5rVP/29/

looping the key/value pairs

I'm trying to loop the key/value pairs I receive below in my query and console out the email address. What I'm I doing wrong?
JSON I receive...
{"ERRORS":[],"DATA":[{"INCENTIVEID":"1","CREATED":"","EMAIL":"email","RECIPIENTID":"1","NAME":"glyn","ACTIVE":0,"MODIFIED":"","MOBILE":"11111111111"},{"INCENTIVEID":"1","CREATED":"","EMAIL":"eee","RECIPIENTID":"2","NAME":"edem","ACTIVE":0,"MODIFIED":"","MOBILE":"11111111111"}],"MESSAGES":[]}
Current Script
$(document).ready(function(){
var digits = /^\d{11}$/;
$("#mobile").on("keyup keypress", function(){
if (digits.test(this.value)) {
$.ajax({
url: "http://api.domain.com/recipients/lookup",
data: {
mobile: this.value,
incentiveID: $("#incentiveID").val()
},
success: function(data){
$.each(data.DATA, function(index, value) {
console.log(value.EMAIL);
});
console.log(data);
}
});
}
});
});
The e-mails are within the DATA array; you should use data.DATA instead of just data, which refers to the entire JSON object:
$.each(data.DATA, function(index, value) {
console.log(value.EMAIL);
});
Added below and issue was resolved. anyone know why?

Infragistics Jquery Tree

I need some help from you in using igTree when LoadOnDemand is set to true.
I have a WCF REST Service which is giving me data to populate in igTree.
Please find the sample code..
$.ajax(
{
type: "GET",
url: "AssessmentProcWCFService.svc/GetAllEntities",
contentType: "application/json; charset=utf-8",
dataType: 'json',
data: '{}',
cache: false,
success: OnGetAllEntitiesSuccess,
error: OnGetAllEntitiesFailure
});
==================================================
function OnGetAllEntitiesSuccess(categoryList) {
$("#APTreeView").igTree({
animationDuration: 0,
dataSourceType: 'json',
dataSource: categoryList.d,
initialExpandDepth: false,
loadOnDemand: true,
dataSourceUrl: "AssessmentProcWCFService.svc/GetAllCategories?EntityID=primaryKey:id",
bindings: {
textKey: 'text',
valueKey: 'id',
primaryKey: 'id',
expanded: 'expanded',
childDataProperty: 'children'
}
});
}
=========================================================
Questions:-
How could I send the selected node ID to the Service when any node of the tree is expanding?
The way I am sending in the above example it is not working when I am retrieving it in the service “public List GetAllCategories()” like
“string entityID = HttpContext.Current.Request.QueryString["EntityID"];”
I am getting entity id as null.
How the tree get rendered when any node get expanded if LoadOnDemand is true?
Please help me on this I have spend lot of time in it.
Basically you can encode anything you like in the request made to the service:
Here are the default request parameters explained: http://www.infragistics.com/community/forums/t/65356.aspx
And here is how you can add a request parameter:
function OnGetAllEntitiesSuccess(categoryList) {
$("#APTreeView").igTree({
animationDuration: 0,
dataSourceType: 'json',
dataSource: categoryList.d,
initialExpandDepth: false,
loadOnDemand: true,
dataSourceUrl: "AssessmentProcWCFService.svc/GetAllCategories?EntityID=primaryKey:id",
bindings: {
textKey: 'text',
valueKey: 'id',
primaryKey: 'id',
expanded: 'expanded',
childDataProperty: 'children'
},
nodePopulating: function (event, ui) {
var node = '&SelectedNodeID=' + $("#APTreeView").igTree('selectedNode').element.attr('data-value'),
myNewUrl = 'AssessmentProcWCFService.svc/GetAllCategories?EntityID=primaryKey:id' + node;
$('#myTree').igTree('option', 'dataSourceUrl', myNewUrl);
}
});
}
