Jquery update ckfinder form field

Question

I'm trying to update an input field value .ckfinder-input via ck finders pop up image selector. It all works fine until I try and assign the selected image URL to the input field input.val() = fileUrl and get the following error message:

ReferenceError: invalid assignment left-hand side

Could someone shed some light on what I'm doing wrong?

My code is as follows:

$(".ckfinder-modal-button").on("click", function() {
  input = $(this).parent().find(".ckfinder-input");
  BrowseServer(input);
});

function BrowseServer(input) {
  var finder = new CKFinder();
  finder.selectActionData = input;
  finder.selectActionFunction = function(fileUrl, data) {
    input = data['selectActionData'];
    console.log(input); //returns Object[input.form-control.ckfinder-input property value = "" attribute value = "null"]
    console.log(fileUrl); //returns "/customer_images/header_images/home.jpg"
    input.val() = fileUrl; // ReferenceError: invalid assignment left-hand side;
  }
  finder.resourceType = 'HeaderImages';
  finder.removePlugins = 'basket';
  finder.popup();
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div class="bootstrap-filestyle input-group">
  <input type="text" class="form-control ckfinder-input" name="ckfinder-input">
  <span class="group-span-filestyle input-group-btn ckfinder-modal-button" tabindex="0">
    <label class="btn btn-default">
      <span class="icon-span-filestyle fa fa-cloud-upload"></span>
  </label>
  </span>
</div>

Answer 1

probably it's because your JavaScript is invalid. You cannot assign a value (fileUrl) to the output of function (input.val()) in: js input.val() = 'abc'; You should either:

a) if it is DOM Input Element: input.value = 'abc';

b) if it's jQuery wrapper for DOM Element: input.val( 'abc' );
