Get value of hidden input populated by jQuery autocomplete - javascript

I am using a jQuery Autocomplete to populate a list of names from a database and then assign the compId number to a hidden input.
I want to be able to access the compId value as soon as the user selects a company and assign it to a variable that I can use in conjunction with PHP and a MySQL statement prior to the user moving on.
Here is the jQuery:
$(function() {
function log( message ) {
$("#compId").val(message);
$( "#compId" ).scrollTop( 0 );
}
$( "#companyForm" ).autocomplete({
source: "/autoComp/companies.php",
minLength: 2,//search after two characters
select: function( event, ui ) {
log( ui.item ? ui.item.id : "");
}
});
});
HTML:
<input type="hidden" id="compId" name="compId" required />
The autocomplete is working fine, just don't know how to access it immediately after the value is filled.
Thanks!

Apologies if I misunderstood what you are asking but there is a response event you can chain on to your autocomplete call like so:
http://api.jqueryui.com/autocomplete/#event-response
$(function() {
function log( message ) {
$("#compId").val(message);
$( "#compId" ).scrollTop( 0 );
}
$( "#companyForm" ).autocomplete({
source: "/autoComp/companies.php",
minLength: 2,//search after two characters
select: function( event, ui ) {
log( ui.item ? ui.item.id : "");
},
response: function () {
alert($("#compId").val());
}
});
});

jQuery autocomplete search and select programmatically

I have a data from my controller and when the page loads I want the autocomplete input to search for that data and select it.
I am able to search the data using:
$( "#autocomplete" ).autocomplete( "search", '<?=$ID?>' );
above code works and showing the correct value of autocomplete. Now I cant select the value so that the autocomplete input triggers change. I wanted the input to trigger change because I will auto populate some input.
The way I select the value pro grammatically is :
select: function( event, ui ) {}
Now i found this:
search: function( event, ui ) {},
Is is possible to combine the two?
How to select searched data from auto complete programmatically ?
Update:
This is how my autcomplete works:
$( ".updatedautocomplete" ).autocomplete({
source:function(request,response){
var $this = $(this);
$.post("url",{
term:request.term
}).done(function(data, status){
response($.map( data, function( item ) {
return {
data
}
return false; // Prevent the widget from inserting the value.
}));
});
},
select: function( event, ui ) {
$( this ).attr( 'data-value' , ui.item.id );
$( this ).attr( 'data-asd' , ui.item.sad );
$( this ).val( ui.item.label );
$( "#modal" ).val( ui.item.qwe.trim() );
$( "#modal" ).val( ui.item.asd.trim() );
$( "#modal" ).val( ui.item.zxc.trim() );
$( "#modal" ).val( ui.item.ert.trim() );
$( "#modal" ).val( ui.item.dfg.trim() );
return false;
}
});
The reason why I wanted select event is to populate some input as shown in the source
You simply do jQuery.val() on the input element, like so.
Edit
Since you seem to want to trigger the selection after an asynchronous data retrieval, you probably want the response event and perform the selection there.
response (event, ui)
Triggered after a search completes, before the menu is shown. Useful for local manipulation of suggestion data, where a custom source option callback is not required. This event is always triggered when a search completes, even if the menu will not be shown because there are no results or the Autocomplete is disabled
$(".updatedautocomplete").autocomplete({
source: function(request, response) {
var $this = $(this);
//$.post("url", {
// term: request.term
//})
//.done(function (data, status) {
// response($.map(data, function (item) {
// return {
// data
// }
// return false; // Prevent the widget from inserting the value.
// }));
//
//});
// Simulates some data returned from server
response([
{ label: "Javascript", value: "js" },
{ label: "CSharp", value: "cs" },
{ label: "PHP", value: "php" }
]);
},
response: function(event, ui) {
// Make your preferred selection here
var item = ui.content[0].label;
$(this).val(item).trigger('change');
}
});

<input class="updatedautocomplete" />
search and select are the events which get triggered when the search is taking place. You don't execute them.
Additionally, I believe the method search (not the event one) is meant rather for "suggesting" users that a value/tag exists in the list and that they need to select it themselves. So, yes, if you need a value programmatically selected (without user interaction) you might need to do it by .val() and optionally .trigger().

Remove/Hide autocomplete list item? [duplicate]

This is rather a simple question, but how do I disable the dropdown of the jQuery Autocomplete? When a user starts typing, I run my own function on the response callback. I don't need anything else to appear. This is what I have:
$( "#search" ).autocomplete({
source: "/app/friends",
minLength: 2,
response: function( event, ui ) {
$(".ui-menu-item").hide(); //i hoped this would work
display(ui.content);
}
});
According to the documentation for the plugin, there is an open event that fires when the menu opens. You can put some code in that event to hide the drop down:
$( "#search" ).autocomplete({
source: "/app/friends",
minLength: 2,
response: function( event, ui ) {
display(ui.content);
},
open: function( event, ui ) {
$(".ui-autocomplete").hide();
}
});

Jquery autocomplete ... call a function after completing ajax

In official documentation page i find below code http://jqueryui.com/autocomplete/#remote
$( "#birds" ).autocomplete({
source: "search.json",
minLength: 2,
select: function( event, ui ) {
log( ui.item ?
"Selected: " + ui.item.value + " aka " + ui.item.id :
"Nothing selected, input was " + this.value );
}
});
What i need is after ajax call is made to search.json , I need to store the returned json data from remote in a variable and then call a function.How to do it ? thanks.
Initialize the autocomplete with the response callback specified:
$( ".selector" ).autocomplete({
response: function( event, ui ) {}
});
Bind an event listener to the autocompleteresponse event:
$( ".selector" ).on( "autocompleteresponse", function( event, ui ) {} );

Javascript Autocomplete email's domain using jQuery UI

I need help, I am stuck with trying to make the following case scenario work:
You have email input field, you type: foo#y - it should pop up autocomplete box, offering yahoo.com (for example).
If you take this suggestion, the end value should become: foo#yahoo.com
I have wrote this code (modified off another jquery UI sample):
$( "#tags" )
// don't navigate away from the field on tab when selecting an item
.bind( "keydown", function( event ) {
if ( event.keyCode === $.ui.keyCode.TAB &&
$( this ).data( "autocomplete" ).menu.active ) {
event.preventDefault();
}
})
.autocomplete({
minLength: 3,
source: function( request, response ) {
var mail_regex = /^([\w.]+)#([\w.]+)$/;
var match = mail_regex.exec(request.term);
if (match)
var matcher = new RegExp( "^" + match[2], "i" );
response( $.grep( availableTags, function( item ){
return matcher.test( item );
}) );
},
focus: function() {
// prevent value inserted on focus
return false;
},
select: function( event, ui ) {
var terms = split( this.value );
// remove the current input
terms.pop();
// add the selected item
terms.push( ui.item.value );
// add placeholder to get the comma-and-space at the end
terms.push( "" );
this.value = terms.join( ", " );
return false;
}
});
Full working interactive sample:
http://jsfiddle.net/rRF2s/3/
However, it REPLACES the foo# with just yahoo.com - I can not for the life of me figure out how to override this behaviour...
Any Javascript/jQuery masters - help please! how to accomplish this goal?
I tried doing: return match[1]+matcher.test( item ), but that does not work.
The select function is assigning the resultant value with this.value =. However it is replacing the input value completely rather than appending it with the drop down value.
Without a great deal of testing the following, simplified function seems to work as required:
select: function( event, ui ) {
this.value = this.value.substring(0, this.value.indexOf('#') + 1) + ui.item.value;
return false;
}
This is taking the first part of the already entered value, for example foo# for the input foo#ya and then adding on the value of the selected item from the drop down.
You may want to trigger the dropdown when someone enters the # symbol (seems more intuitive to me) and if so, this function may also need modifying to correctly extract the user entered value.
Here is the complete code:
$(function() {
var availableTags = [
"Yahoo.com",
"Gmail.com"
];
function extractLast( val ) {
if (val.indexOf("#")!=-1){
var tmp=val.split("#");
console.log(tmp[tmp.length-1]);
return tmp[tmp.length-1];
}
console.log("returning empty");
return "";
}
$( "#tags" )
// don't navigate away from the field on tab when selecting an item
.bind( "keydown", function( event ) {
if ( event.keyCode === $.ui.keyCode.TAB &&
$( this ).data( "autocomplete" ).menu.active ) {
event.preventDefault();
}
})
.autocomplete({
minLength: 1,
source: function( request, response ) {
var mail = extractLast(request.term);
if(mail.length<1){return;}
var matcher = new RegExp( "^" + mail, "i" );
response( $.grep( availableTags, function( item ){
return matcher.test( item );
}));
},
focus: function() {
// prevent value inserted on focus
return false;
},
select: function( event, ui ) {
var terms = this.value.split(", ");
// remove the current input
var ml=terms[terms.length-1].split("#")[0];
terms.pop();
// add the selected item
terms.push( ml+"#"+ui.item.value );
// add placeholder to get the comma-and-space at the end
terms.push( "" );
this.value = terms.join( ", " );
return false;
}
});
});

Select first jquery UI result automatically

I am using jQuery Autocomplete to search a local database of cities. Here is the code:
$('#txt_search_city').autocomplete({
source: url,
delay: 0,
autoFocus: true,
select: function( event, ui ) {
$( "#id_city" ).val( ui.item.id );
$(this).closest('form').submit();
},
focus: function( event, ui ) { event.preventDefault(); }
});
I'd like the first returned value to be selected by default (like it works on facebook). So essentially, if they just hit enter they will trigger the selection of the first result.
I thought that's what autoFocus: true did, but it isn't working. Not showing errors, just not selecting the first result.
Thoughts?
Autofocus will highlight the first record..
Your code would then just need to include autoFocus: true, like below:
$('#txt_search_city').autocomplete({
source: url,
delay: 0,
autoFocus: true,
select: function( event, ui ) {
$( "#id_city" ).val( ui.item.id );
$(this).closest('form').submit();
},
focus: function( event, ui ) { event.preventDefault(); }
});
This seems to be outdated. I had the same problem.
Just use .autocomplete({autoFocus: true})
I'm using jquery-ui-1.10.0.min and it works now.
No plug is needed.
