What I have tried:

I am using jquery autosuggestion. My code is:
$(".autosuggest").each(function(){

$(this).autocomplete({

source: function(request, response) {
$.ajax({
url: "autocomp3.asp",
dataType: "json",
data: {
term : request.term,
param : paramName,
con : con,
ver : lang
//country_id : $("#country_id").val()
},
success: function(data) {

$.each(data, function(i) {
//outputdata[i] = data[i].value;
outputdata = data;
//alert (data[i]);
});
if (data == "")
{
$("#loc").html("No result found, please check your spelling and try again.");
$("#disBtn").css("display", "none");
}else{
$("#disBtn").css("display", "block");
$("#loc").html("");
}
response(data);
}
});
},
search: function () {
$(this).addClass('loadinggif');
$("#"+hiddenIdField+"").val("");
},
response: function (event, ui) {

$(this).removeClass('loadinggif');
len = ui.content.length;
//alert(ui.item.value);
},
minLength: 1,
delay: 300,
select: function (event, ui) {

//$("#txtAllowSearch").val(ui.item.label); // display the selected text
$("#"+hiddenIdField+"").val(ui.item.id); // save selected id to hidden input
}
});
});

Look at the supported events in the documentation (especially "search")

Autocomplete Widget | jQuery UI API Documentation[^]

If you need help implementing one google and you'll find source code.
