xeditable & select2 dropdown w/ajax source displaying empty after submitting

I've gotten xeditable and select2 to work with an api call as the source and everything works great EXCEPT the following.
After submitting the select2 dropdown, the value of the table is displayed as EMPTY and requires a page refresh in order to update to the correct value.
Does anyone know how to update the value to the selected select2 dropdown value?
my html:
<td class="eo_role"><a href="#" data-pk={{r.pk}} data-type="select2" data-url="/api/entry/{{r.pk}}/"
data-name="eo_role" data-title="Enter EO_role">{{r.eo_role}}</a></td>
here is my JS:
$('#example .eo_role a').editable( {
params: function(params) { //params already contain `name`, `value` and `pk`
var data = {};
data[params.name] = params.value;
return data;
},
source: 'http://localhost:8000/api/eo_role/select_two_data/',
tpl: '<select></select>',
ajaxOptions: {
type: 'put'
},
select2: {
cacheDatasource:true,
width: '150px',
id: function(pk) {
return pk.id;
},
ajax: {
url: 'http://localhost:8000/api/eo_role/select_two_data/',
dataType: "json",
type: 'GET',
processResults: function(item) {return item;}
}
},
formatSelection: function (item) {
return item.text;
},
formatResult: function (item) {
return item.text;
},
templateResult: function (item) {
return item.text;
},
templateSelection : function (item) {
return item.text;
},
});
Again - everything works (database updates, dropdownlist populates etc.) however the <td> gets updated with "EMPTY" after submitting the dropdown - requiring a page refresh to show the correct value.

I figured out a workaround. I'm SUPER PUMPED.
//outside of everything, EVERYTHING
//test object is a global holding object that is used to hold the selection dropdown lists
//in order to return the correct text.
var test = {};
$('#example .eo_role a').editable( {
params: function(params) { //params already contain `name`, `value` and `pk`
var data = {};
data[params.name] = params.value;
return data;
},
//MUST be there - it won't work otherwise.
tpl: '<select></select>',
ajaxOptions: {
type: 'put'
},
select2: {
width: '150px',
//tricking the code to think its in tags mode (it isn't)
tags:true,
//this is the actual function that triggers to send back the correct text.
formatSelection: function (item) {
//test is a global holding variable set during the ajax call of my results json.
//the item passed here is the ID of selected item. However you have to minus one due zero index array.
return test.results[parseInt(item)-1].text;
},
ajax: {
url: 'http://localhost:8000/api/eo_role/select_two_data/',
dataType: "json",
type: 'GET',
processResults: function(item) {
//Test is a global holding variable for reference later when formatting the selection.
//it gets modified everytime the dropdown is modified. aka super convenient.
test = item;
return item;}
}
},
});

I faced that same issue. I handle it that way:
In x-editable source code look for:
value2html: function(value, element) {
var text = '', data,
that = this;
if(this.options.select2.tags) { //in tags mode just assign value
data = value;
//data = $.fn.editableutils.itemsByValue(value, this.options.select2.tags, this.idFunc);
} else if(this.sourceData) {
data = $.fn.editableutils.itemsByValue(value, this.sourceData, this.idFunc);
} else {
//can not get list of possible values
//(e.g. autotext for select2 with ajax source)
}
As you can see, there is else statment, without any code (only 2 comments) that is the situation, with which we have a problem. My solution is to add missing code:
(...) else {
//can not get list of possible values
//(e.g. autotext for select2 with ajax source)
data = value;
}
That's fix problem without tags mode enabled. I do not detect any unwanted behaviors so far.
Example code:
jQuery('[data-edit-client]').editable({
type: 'select2',
mode: 'inline',
showbuttons: false,
tpl: '<select></select>',
ajaxOptions: {
type: 'POST'
},
select2: {
width: 200,
multiple: false,
placeholder: 'Wybierz klienta',
allowClear: false,
formatSelection: function (item) {
//test is a global holding variable set during the ajax call of my results json.
//the item passed here is the ID of selected item. However you have to minus one due zero index array.
return window.cacheData[parseInt(item)].text;
},
ajax: {
url: system.url + 'ajax/getProjectInfo/',
dataType: 'json',
delay: 250,
cache: false,
type: 'POST',
data: {
projectID: system.project_id,
action: 'getProjectClients',
customer: parseInt(jQuery("[data-edit-client]").attr("data-selected-company-id"))
},
processResults: function (response) {
window.cacheData = response.data.clients;
return {
results: response.data.clients
};
}
}
}
});

Set data of a Multiple Select2 element through javascript

I'm loading multiple values into a Select2 element through Javascript, ajax and jquery. While the data is loading properly and can be accessed once loaded, I'm unable to set stored data in the Select2 element.
Edit: I'm using Select2 v3.5.
My code:
HTML:
<input class="jsData" style="width: 100%" id="select2Data"></input>
Javascript:
$(".jsData").select2({
ajax: {
minimumInputLength: 4,
contentType: 'application/json',
url: '<%=Url.Action("GetData","Controller")%>',
type: 'POST',
dataType: 'json',
data: function (term) {
return {
sSearchTerm: term
};
},
results: function (data) {
return {
results: $.map(JSON.parse(data), function (item) {
return {
text: item.term,
slug: item.slug,
id: item.Id
}
})
};
}
},
multiple: true
});
So, this creates a Select2 element where I can traverse to and from a database and load data depending on what I've typed. I can also access the data (entered by the user) using the following line:
$('.jsData').select2('val')
The above line returns an array, which I can store in the database. My current objective is to set the stored data back into the Select2 element. Any help in this matter would be most welcome.
Update: A relevant link for what I want to accomplish:
https://select2.github.io/examples.html#programmatic
I want the example of setting multiple elements in Select2. However, the difference would be in the fact that the example in the Select2 documentation brings data at the time of loading the page, while I will be making trips to fetch the data.

The Select2 v3.5.4 docs are a bit confusing around this. I think there's a typo in the docs that's misleading.
First, notice that when I retrieve the data from the remote source I'm returning it as an object in the format of {id: ##, name: NAME}.
The first step is to add the initSelection parameter and pass the function to retrieve the previously selected items.
The next step, where I believe there's a typo, is to define the formatSelection parameter (not the formatResult it states in the docs). This function defines how the previously selected result is displayed. In this case I'm merely showing the name property of the result.
The formatResult parameter defines how newly selected options are displayed. You'll notice formatResult and formatSelection are the same below. I could have reused a single function but felt this was better for demonstration.
$(document).ready(function() {
function formatResult(data) {
return data.name;
};
function formatSelection(data) {
return data.name;
}
$(".jsData").select2({
ajax: {
minimumInputLength: 4,
url: "https://jsonplaceholder.typicode.com/users",
type: "GET",
dataType: "json",
results: function(data) {
return {
results: $.map(data, function(user) {
return {
name: user.name,
id: user.id
};
})
};
}
},
initSelection: function(element, callback) {
var id = $(element).val();
if (id !== "") {
$.ajax("https://jsonplaceholder.typicode.com/users/" + id, {
dataType: "json"
}).done(function(data) {
callback(data);
});
}
},
formatResult: formatResult,
formatSelection: formatSelection,
multiple: true
});
});
Here's the full working example:
$(document).ready(function() {
function formatResult(data) {
return data.name;
};
function formatSelection(data) {
return data.name;
}
$(".jsData").select2({
ajax: {
minimumInputLength: 4,
url: "https://jsonplaceholder.typicode.com/users",
type: "GET",
dataType: "json",
results: function(data) {
return {
results: $.map(data, function(user) {
return {
name: user.name,
id: user.id
};
})
};
}
},
initSelection: function(element, callback) {
var id = $(element).val();
if (id !== "") {
$.ajax("https://jsonplaceholder.typicode.com/users/" + id, {
dataType: "json"
}).done(function(data) {
callback(data);
});
}
},
formatResult: formatResult,
formatSelection: formatSelection,
multiple: true
});
});
.jsData {
width: 200px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

set data attributes with ajax and select2

I'm trying setup data attributes into select2 options but without success, at this moment i have the following JS code
_properties.$localElement.select2({
ajax: {
url: "url",
type: "POST",
dataType: 'json',
delay: 250,
data: function (params) {
return {
name: params.term, // search term
type: 1
};
},
processResults: function (data) {
return {
results: $.map(data, function (item) {
return {
text: item.name,
source: item.source,
id: item.id
}
})
};
},
cache: true
},
//define min input length
minimumInputLength: 3,
});
And i want setup a data-source for the selected option value.

I find the solution, looks that resultTemplate dont format the "visual" selected option , need to use templateSelection option:
templateSelection: function(container) {
$(container.element).attr("data-source", container.source);
return container.text;
}

I solved this problem.
$('select').on('select2:select', function (e) {
var data = e.params.data;
$("select option[value=" + data.id + "]").data('source', data.source);
$("select").trigger('change');
});

You can actually use the exact syntax, that you already used. The "source-attribute" just needs to be accessed via data().data.source of the specific select2-option.
So keep your processResults function like you did:
processResults: function (data) {
return {
results: $.map(data, function (item) {
return {
text: item.name,
source: item.source,
id: item.id
}
})
};
},
and if you want to retrieve the source of the selected option, you can do it like this:
var selectedSelect2OptionSource = $("#idOfTheSelect2 :selected").data().data.source;
In fact you can set any variable you want in your processResults function and then select it via data().data.variableName!

two ajax request url (success/fail)

Good day,
I was in some disarray . I have a ajax request from select2. Also I have two urls. How should I event organized If / else success/failure statements, if suddenly one will not work , then send an inquiry to another link?
I'm trying again and again and alwas there is error somewhere((
$(".js-data-example-ajax").select2({
language: "ru",
placeholder: "Serach.........",
disabled: false,
selected: true,
ajax: {
url: "url_1",
dataType: 'json',
delay: 250,
data: function (params) {
return {
q: params.term + "%", // search term
};
},
processResults: function (data) {
if (data.features.length > 0) {
var resultArray = [];
$.each(data.features, function (index, value) {
value.attributes.id = value.attributes.OBJECT_ID;
resultArray.push(value.attributes);
});
return {
results: resultArray
};
} else {
return []
};
},
cache: true
},
escapeMarkup: function (markup) { return markup; }, // let our custom formatter work
minimumInputLength: 5,
templateResult: formatRepo, // omitted for brevity, see the source of this page
templateSelection: formatRepoSelection // omitted for brevity, see the source of this page
});

It should be quite simple because you only have to call the first url and, on error, call the second.
$.ajax(function(data){
url: "url_1",
...,
success(function(data){
//do stuff on success
}),
error(function(e){
$.ajax(function(data{
//call the second url
})
})
})

Select2 - disable the user input choice

I'm trying to set datas from ajax in a select2 select...
But the problem is that if I write something which isn't in my datas i can select this choice !
And this will take this value "I don't exist" ... The formatNoMatches() function seems not to be called ...
JS :
$(".select2-ajax").select2({
ajax: {
url: "ajax.call.php",
type:'POST',
dataType: 'json',
data: function (params) {
return {
nom: params.term, // search chars
page: params.page,
};
},
processResults: function (data, page) {
console.log(data.data);
if(typeof(data.data)=='undefined' || !data.data || data.data.length <= 0)
var res = [];
else
{
var res = [];
for (var i = data.data.length - 1; i >= 0; i--)
{
res.push({"text":data.data[i]["nom"]+' '+data.data[i]["prenom"],"id":data.data[i]["id_salarie"]});
};
}
return { results: res};
},
cache: true
},
formatNoMatches: function( term ) {
return "<li class='select2-no-results'>' "+term+" ': Aucun résultat</li>";
},
allowClear: true,
language: 'fr',
multiple: false,
I tried the two following after seeing THIS question : ( but still don't work )
selectOnBlur:false,
createSearchChoice: false,
escapeMarkup: function (markup) { return markup; },
minimumInputLength: 1,
});

This should only happen if you are returning an option from your server that matches the text the user entered or you are using the tags option.
Since you don't appear to be using tags, and your code doesn't include it, you can ensure this is not the issue by overriding createTag (previously createSearchChoice to always return null.
$('select').select2({
createTag: function () {
// Disable tagging
return null;
}
});

Set tags to false. Example:
$('select').select2({
tags: false
});
