I have this (bootstrap) form with three elements. As the button is clicked, another line with three elements is added.
<div class="row align-items-center mb-2 mt-2 ms-1 ">
<div class="col-5 ps-1 pe-1">
<select class="form-select example-select" id="cmbSelect[]" name="cmbSelect[]">
<option>1</option>
<option>2</option>
<option>3</option>
</select>
</div>
<div class="col-4 ps-1 pe-1">
<input class="form-control" type="text" name="txtFirst[]">
</div>
<div class="col-2 ps-1 pe-1">
<input class="form-control" type="text" name="txtSecond[]" value="3">
</div>
<div class="col-1 ps-1 pe-1">
<a href="javascript:void(0);" class="add_button" title="Add one more element"><img src="../img/add-icon.png"/ alt="Add"></a>
</div>
</div>
I would like to execute a JS function if the first element cmbSelect[] is clicked. The function must get the element that triggered the event, because its selected item should be edited. Furthermore the value of the element next to the one that triggered the event should be updated.
What is the best way doing this?
I tried something like this:
var example_select = $(".example-select");
var all = $(".example-select").map(function() {
this.on("click", function (element) {
console.log("clicked");
return element.innerHTML;
});
}).get();
console.log(all.join());
But example_select is empty and the click event is not fired...
map is not used like this, you will get Uncaught TypeError: this.on is not a function
You just need to use on to listen for event
e.g.
var example_select = $(".example-select");
$('input[type=text]').on('input', function(element) {
console.log("input");
});
$('select').on('change', function(element) {
const isFirst = $(this).children('option:first-child').is(':selected');
console.log(`The current option val: ${$(this).val()}`);
console.log(`Is it the first option: ${isFirst}`);
