I have below autocomplete code, which works fine When i type one or more letters.
$("body").on('focus', 'input.sub-category', function () {
var id = $(this).data('thiscatid');
var term = $(this).val();
$(this).autocomplete({
minLength: 0,
source: function( request, response ) {
$.post( base_url + 'ajax/getSubCats',
{ parent_id: id, term: term},
function( data ) {
response(data);
},
'json'
);
},
select:function(event,ui){
$(".sub-cat").val(ui.item.label);
return false;
},
change: function(event, ui) {
console.log(this.value);
if (ui.item == null) {
this.setCustomValidity("You must select a category");
}
}
});
});
I would like to populate the drop down with all of the matching words from the database on just focusing the input box. That means even without typing a single word. When i just focus, the function is called, but nothing within the function $(this).autocomplete({
is executed. Any idea why autocomplete not working when focus in on the input field?
Use below code it will work as per your requirement.
$("body input.sub-category").each(function{
$(this).on('focus', 'input.sub-category', function () {
var id = $(this).data('thiscatid');
var term = $(this).val();
$(this).autocomplete({
minLength: 0,
source: function( request, response ) {
$.post( base_url + 'ajax/getSubCats',
{ parent_id: id, term: term},
function( data ) {
response(data);
},
'json'
);
},
select:function(event,ui){
$(".sub-cat").val(ui.item.label);
return false;
},
change: function(event, ui) {
console.log(this.value);
if (ui.item == null) {
this.setCustomValidity("You must select a category");
}
}
});
});
});
If this is not work add status in comment.
I was able to fix by adding one more function. So there is one function executing on keyup and another one on focus.
$("body").on('keyup', 'input.sub-category', function () {
var id = $(this).data('thiscatid');
var term = $(this).val()?$(this).val():"";
$(this).autocomplete({
minLength: 0,
autoFocus: true,
source: function( request, response ) {
$.post( base_url + 'ajax/getSubCats',
{ parent_id: id, term: term},
function( data ) {
response(data);
},
'json'
);
},
select:function(event,ui){
$(this).val(ui.item.label);
return false;
},
change: function(event, ui) {
if (ui.item == null) {
this.setCustomValidity("You must select a category");
}
}
});
});
Above one executes on keyup and below one on focus.
$("body").on('focus', 'input.sub-category', function () {
var id = $(this).data('thiscatid');
var term = $(this).val()?$(this).val():"";
$(this).autocomplete({
minLength: 0,
autoFocus: true,
source: function( request, response ) {
$.post( base_url + 'ajax/getSubCats',
{ parent_id: id, term: term},
function( data ) {
response(data);
},
'json'
);
},
select:function(event,ui){
$(this).val(ui.item.label);
return false;
},
change: function(event, ui) {
if (ui.item == null) {
this.setCustomValidity("You must select a category");
}
}
});
$(this).autocomplete("search", "");
});
