I want to know how to get with jquery with method val() the selected value of a select tag through a custom attribute inside it.
Example:
<select dta-tble="table1" onchange="printTable(event);">
var datatable = $(evt.target).attr("**dta-tble**");
var row = $(**..this the solution..**).val();
Thanks.
try:
var value = $('select[**dta-tble**="table1"]').val();
I recomand you don't use ** characters on html attributed, use example data-table="table1" or id="table1" and you can get value more easly
If you're using jQuery, dont use inline event handlers. You can target elements using the attribute selector
$("select[dta-tble]").on("change", function(){
const val = $(this).val();
console.log(val);
});<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<select dta-tble="table1">
<option>1</options>
<option>2</options>
<option>3</options>
</select>
