Programmatically setting a value


This is my code:

$('#holidaySummary_clientID').prop("readonly", true);

under ‘success’ Ajax callback function.

When these statements are executed, the following occurs:
1 the mentioned select set a blank value.
2 the response[0].name isn’t being setted as a value for this select.
3 the mentioned select DOESN’T set to readonly.

The view:

    <div class="col-md-4" style="padding-left: 15px;padding-right: 15px">
                                    <div class="form-group form-group-material">
                                        <label class="control-label is-visible">
                                            {{ form_label(form.clientID, 'Proposal Client', {'label_attr': {'class': 'control-label is-visible'}}) }} *
                                        {{ form_widget(form.clientID, { 'attr' : {'class' : 'select2 form-control', 'placeholder' : 'Proposal Client'} }) }}

What’s wrong?

Can you provide the rendered HTML and also the complete JavaScript code where you initialize the Select2, including your AJAX success handler? I can’t tell from the code you’ve provided what is actually happening.

$(document).ready(function() {


        $('#holidaySummary_proposalID').on('change', function (e) {
                var data = $(this).select2('data')[0].text;
                console.log(data); // 1005) 5280 MKMEDIA_250PAX_MARZO_151392
                var title = getDataFromProposal(
                    1 // 0 = id; 1 = title
                    var proposalID = getDataFromProposal(
                    0 // 0 = id; 1 = title
                    url: "/events/getClientByProposalID",
                    type: "POST",
                    dataType: 'json',
                    data: {
                        "proposalID": proposalID
                    success: function (response) {
                        var clientName = response[0].name;
                        var clientID = response[0].id;

                        console.log(clientID); // 170
                        console.log(clientName); // MK MEDIA
               1:         $('#holidaySummary_clientID').val(clientID).text(clientName).trigger('change');
                    error: function(XMLHttpRequest, textStatus, errorThrown){

                $('#holidaySummary_clientID').on('change', function (e) {
    console.log("hola"); // It prints
    // The assigned values (line :1) aren't showed. Blank item
                  //  var theID = $('#holidaySummary_clientID').select2('data').id;
                  //  var theSelection = $('#holidaySummary_clientID').select2('data').text;
                    // $('#holidaySummary_clientID').text(theID);
                   // $('#holidaySummary_clientID').text(theSelection);


            function getDataFromProposal(proposalValue, pos) {
                return proposalValue.split(') ')[pos];

I am using Symfony to populate the first select: #holidaySummary_proposalID and the second one, #holidaySummary_clientID, but I don’t think it is relevant for this issue.

Thanks for your priceless time.

Kindest regards.

I have recorded a video with OBS Studio. It weights only 7mb. I could transfer it by using WeTransfer to your email if you would like :slight_smile:

Kindest regards.

I am still a little unclear about whether your AJAX success handler is trying to programmatically select an existing value in the holidaySummary_clientID Select2, or trying to create a new <option> in that Select2. Assuming you’re trying to select an existing value, you should not call the text() method in this line:


Instead, you should do this:


I’ve tested this (simulating the AJAX response since I don’t have access to your URL) and it works for me. When I select the item in the first Select2, the third Select2 gets its value set.

I was wrong: I had passed clientNAME instead of clientID.

Thanks for your priceless time and support.

Kindest regards.
