jQuery ui autocomplete combobox - default value when user enters non valid value

EDIT: Doh! I should have placed my code here too! Here it is:
My code to call the combobox:
jQuery( "#select_performance" ).combobox();
jQuery( "#select_state" ).combobox();
jQuery( "#select_postcode" ).combobox();
jQuery( "#select_install" ).combobox();
jQuery( "#select_customer" ).combobox();
jQuery( "#select_address" ).combobox();
My code (as is from JQuery ui) to define the fields:
/*** Set up multiselect drop down lists ***/
(function( $ ) {
$.widget( "custom.combobox", {
_create: function() {
this.wrapper = $( "<span>" )
.addClass( "custom-combobox" )
.insertAfter( this.element );
this.element.hide();
this._createAutocomplete();
this._createShowAllButton();
},
_createAutocomplete: function() {
var selected = this.element.children( ":selected" ),
value = selected.val() ? selected.text() : "";
this.input = $( "<input>" )
.appendTo( this.wrapper )
.val( value )
.attr( "title", "" )
.addClass( "custom-combobox-input ui-widget ui-widget-content ui-state-default ui-corner-left" )
.autocomplete({
delay: 0,
minLength: 0,
source: $.proxy( this, "_source" )
})
.tooltip({
tooltipClass: "ui-state-highlight"
}).on('mouseup', function() {
$(this).select();
});
this._on( this.input, {
autocompleteselect: function( event, ui ) {
ui.item.option.selected = true;
this._trigger( "select", event, {
item: ui.item.option
});
},
autocompletechange: "_removeIfInvalid"
});
},
_createShowAllButton: function() {
var input = this.input,
wasOpen = false;
$( "<a>" )
.attr( "tabIndex", -1 )
.attr( "title", "Show All Items" )
.tooltip()
.appendTo( this.wrapper )
.button({
icons: {
primary: "ui-icon-triangle-1-s"
},
text: false
})
.removeClass( "ui-corner-all" )
.addClass( "custom-combobox-toggle ui-corner-right" )
.mousedown(function() {
wasOpen = input.autocomplete( "widget" ).is( ":visible" );
})
.click(function() {
input.focus();
// Close if already visible
if ( wasOpen ) {
return;
}
// Pass empty string as value to search for, displaying all results
input.autocomplete( "search", "" );
});
},
_source: function( request, response ) {
var matcher = new RegExp( $.ui.autocomplete.escapeRegex(request.term), "i" );
response( this.element.children( "option" ).map(function() {
var text = $( this ).text();
if ( this.value && ( !request.term || matcher.test(text) ) )
return {
label: text,
value: text,
option: this
};
}) );
},
_removeIfInvalid: function( event, ui ) {
// Selected an item, nothing to do
if ( ui.item ) {
return;
}
// Search for a match (case-insensitive)
var value = this.input.val(),
valueLowerCase = value.toLowerCase(),
valid = false;
this.element.children( "option" ).each(function() {
if ( $( this ).text().toLowerCase() === valueLowerCase ) {
this.selected = valid = true;
return false;
}
});
// Found a match, nothing to do
if ( valid ) {
return;
}
// Remove invalid value
this.input
.val( "" )
.attr( "title", value + " didn't match any item" )
.tooltip( "open" );
this.element.val( "" );
this._delay(function() {
this.input.tooltip( "close" ).attr( "title", "" );
}, 2500 );
this.input.data( "ui-autocomplete" ).term = "";
},
_destroy: function() {
this.wrapper.remove();
this.element.show();
}
});
})( jQuery );
I have 6 jQuery autocomplete comboboxes on a page. Each has selected a default item set up on load (first item of the list). When a user types in an invalid entry, (or blanks the input box) I get the tooltip saying "invalid entry". Is there a way to have the value be re-set to the initially selected / default entry (first list item)?
I cannot seem to find the answer to this (or perhaps I am asking the wrong way).
Thanks!

I don't know how you're setting your default value but here's a clue of how to go about it.
change: function (event, ui) {
if (ui.item === null) { // if value typed in the box doesn't exist then
$(this).val(""); // set value to empty string
$(this).val(list[0]).data('autocomplete')._trigger('select'); set new value here and then trigger reset. Assuming list is your array of items, select the first item
}
}

Why is jQuery not seting my select to the selected value

I have standard select which is turned into a combobox using jQuery.
<select name="Searchby" id="Searchby">
<option value="all" >All Departments</option>
<option value="music" >Music</option>
<option value="dvd" >DVD</option>
<option value="bluray" >Bluray</option>
<option value="Artist" >Artist</option>
</select>
Then I have an input which has jQuery's autocomplete on it with categories. When a person types into the input, it returns options to choose from in different categories. If they click on a option I want it to change what is selected in the select above. Here is my code that I tried.
$("#Search").catcomplete({
delay: 1000,
source: "Drop_Down_Search.php",
select: function(event, ui) {
if (ui.item.category = 'Artist') {
$('#Searchby').val('Artist');
console.log(ui.item.category);
}
}
});
The console is logging that it is working and it posts correctly to the search results page but doesn't change before you move off the page. It just stays as 'all departments'. I need it to change so a person who is searching can see they will only search for 'Artist' or 'Blu-Rays' before they move to the search results page.
EDIT:
Ok so as it turns out without the jquery combobox set on the select it does change the value, but when you use jquery's combobox it doesn't change.
What should I be using to change the value once a select has been changed into a combobox?
Here is the combobox code:
(function( $ ) {
$.widget( "ui.combobox", {
_create: function() {
var input,
that = this,
wasOpen = false,
select = this.element.hide(),
selected = select.children( ":selected" ),
value = selected.val() ? selected.text() : "",
wrapper = this.wrapper = $( "<span>" )
.addClass( "ui-combobox" )
.insertAfter( select );
function removeIfInvalid( element ) {
var value = $( element ).val(),
matcher = new RegExp( "^" + $.ui.autocomplete.escapeRegex( value ) + "$", "i" ),
valid = false;
select.children( "option" ).each(function() {
if ( $( this ).text().match( matcher ) ) {
this.selected = valid = true;
return false;
}
});
if ( !valid ) {
// remove invalid value, as it didn't match anything
$( element )
.val( "" )
.attr( "title", value + " didn't match any item" )
.tooltip( "open" );
select.val( "" );
setTimeout(function() {
input.tooltip( "close" ).attr( "title", "" );
}, 2500 );
input.data( "ui-autocomplete" ).term = "";
}
}
input = $( "<input>" )
.appendTo( wrapper )
.val( value )
.attr( "title", "" )
.addClass( "ui-state-default ui-combobox-input" )
.autocomplete({
delay: 0,
minLength: 0,
source: function( request, response ) {
var matcher = new RegExp( $.ui.autocomplete.escapeRegex(request.term), "i" );
response( select.children( "option" ).map(function() {
var text = $( this ).text();
if ( this.value && ( !request.term || matcher.test(text) ) )
return {
label: text.replace(
new RegExp(
"(?![^&;]+;)(?!<[^<>]*)(" +
$.ui.autocomplete.escapeRegex(request.term) +
")(?![^<>]*>)(?![^&;]+;)", "gi"
), "<strong>$1</strong>" ),
value: text,
option: this
};
}) );
},
select: function( event, ui ) {
ui.item.option.selected = true;
that._trigger( "selected", event, {
item: ui.item.option
});
},
change: function( event, ui ) {
if ( !ui.item ) {
removeIfInvalid( this );
}
}
})
.addClass( "ui-widget ui-widget-content ui-corner-left" );
input.data( "ui-autocomplete" )._renderItem = function( ul, item ) {
return $( "<li>" )
.append( "<a>" + item.label + "</a>" )
.appendTo( ul );
};
$( "<a>" )
.attr( "tabIndex", -1 )
.attr( "title", "Select A Critera to Search In " )
.appendTo( wrapper )
.button({
icons: {
primary: "ui-icon-triangle-1-s"
},
text: false
})
.removeClass( "ui-corner-all" )
.addClass( "ui-corner-right ui-combobox-toggle" )
.mousedown(function() {
wasOpen = input.autocomplete( "widget" ).is( ":visible" );
})
.click(function() {
input.focus();
// close if already visible
if ( wasOpen ) {
return;
}
// pass empty string as value to search for, displaying all results
input.autocomplete( "search", "" );
});
},
_destroy: function() {
this.wrapper.remove();
this.element.show();
}
});
})( jQuery );
$(function() {
$( "#Searchby" ).combobox();
$( "#toggle" ).click(function() {
$( "#Searchby" ).toggle();
}); });

mistake i found..
$( "#Search" ).catcomplete({
delay: 1000,
source: "Drop_Down_Search.php",
select: function( event, ui ) {
if (ui.item.category == 'Artist') {
-----^^-- missing `=` in if since your are comparing this
$('#Searchby').val('Artist');
console.log(ui.item.category);
}
}
});
//}); extra brakets..

I found what I was looking for in this answer
How to define selected value for jQuery UI combobox?
After some editing I came to this which worked.
$('.ui-autocomplete-input').val($("#Searchby").val("Artist").val());
The value you select is 'Artist' and Searchby is the select id

Jquery different versions. Jquery Searchable Autosuggest

I have to use two jquery API's, "jquery-1.8.3.js" and "jquery-ui.js" in my code.
But there are already older versions of jquery. And because of this the form is not working properly.
So I search on net for solution and found, we can use
<script>
var jq13 = jQuery.noConflict(true);
</script>
But I have to api's, so I created two variables but still it is not working.
This is my code:-
<script>
(function( $ ) {
$.widget( "ui.combobox", {
_create: function() {
var input,
that = this,
select = this.element.hide(),
selected = select.children( ":selected" ),
value = selected.val() ? selected.text() : "",
wrapper = this.wrapper = $( "<span>" )
.addClass( "ui-combobox" )
.insertAfter( select );
function removeIfInvalid(element) {
var value = $( element ).val(),
matcher = new RegExp( "^" + $.ui.autocomplete.escapeRegex( value ) + "$", "i" ),
valid = false;
select.children( "option" ).each(function() {
if ( $( this ).text().match( matcher ) ) {
this.selected = valid = true;
return false;
}
});
if ( !valid ) {
// remove invalid value, as it didn't match anything
$( element )
.val( "" )
.attr( "title", value + " didn't match any item" )
.tooltip( "open" );
select.val( "" );
setTimeout(function() {
input.tooltip( "close" ).attr( "title", "" );
}, 2500 );
input.data( "autocomplete" ).term = "";
return false;
}
}
input = $( "<input>" )
.appendTo( wrapper )
.val( value )
.attr( "title", "" )
.addClass( "ui-combobox-input" )
.autocomplete({
delay: 0,
minLength: 0,
source: function( request, response ) {
var matcher = new RegExp( $.ui.autocomplete.escapeRegex(request.term), "i" );
response( select.children( "option" ).map(function() {
var text = $( this ).text();
if ( this.value && ( !request.term || matcher.test(text) ) )
return {
label: text.replace(
new RegExp(
"(?![^&;]+;)(?!<[^<>]*)(" +
$.ui.autocomplete.escapeRegex(request.term) +
")(?![^<>]*>)(?![^&;]+;)", "gi"
), "<strong>$1</strong>" ),
value: text,
option: this
};
}) );
},
select: function( event, ui ) {
ui.item.option.selected = true;
that._trigger( "selected", event, {
item: ui.item.option
});
},
change: function( event, ui ) {
if ( !ui.item )
return removeIfInvalid( this );
}
})
.addClass( "ui-widget ui-widget-content ui-corner-left" );
input.data( "autocomplete" )._renderItem = function( ul, item ) {
return $( "<li>" )
.data( "item.autocomplete", item )
.append( "<a>" + item.label + "</a>" )
.appendTo( ul );
};
$( "<a>" )
.attr( "tabIndex", -1 )
//.attr( "title", "Show All Items" )
.tooltip()
.appendTo( wrapper )
.button({
icons: {
primary: "ui-icon-triangle-1-s"
},
text: false
})
.removeClass( "ui-corner-all" )
.addClass( "ui-corner-right ui-combobox-toggle" )
.click(function() {
// close if already visible
if ( input.autocomplete( "widget" ).is( ":visible" ) ) {
input.autocomplete( "close" );
removeIfInvalid( input );
return;
}
// work around a bug (likely same cause as #5265)
$( this ).blur();
// pass empty string as value to search for, displaying all results
input.autocomplete( "search", "" );
input.focus();
});
},
destroy: function() {
this.wrapper.remove();
this.element.show();
$.Widget.prototype.destroy.call( this );
}
});
})( jQuery );
$(function() {
$( "#driver_uuidHOS" ).combobox();
});
</script>
And I have declared two variables:-
<script src="js/new/jquery-1.8.3.js"></script>
<script>
var jq13 = jQuery.noConflict(true);
</script>
<script src="js/new/jquery-ui.js"></script>
<script>
var jq131 = jQuery.noConflict(true);
</script>
So please tell me where I have to use jq13 and where jq131 in my code. This code is for searchable autosuggest.
Thanks in advance.

After you load the first version, you can assign it to a variable.
var jq13 = jQuery.noConflict(true); // as you did
And then load your second jQuery version. The first one you load can be accessed with jq13(...) while the second one can be accessed with $(...).
No need for assgning variable to second script...

You want to load one version of jQuery, then all the plugins for that version, then turn on no conflict mode. You can repeat this process as many times as you'd like (once for each version of jQuery core that you need to load).
So, for your specific case what you want to do is:
<script src="js/new/jquery-1.8.3.js"></script>
<script src="js/new/jquery-ui.js"></script>
<script src="path/to/your/code.js"></script>
<script>jQuery.noConflict(true);</script>
The path/to/your/code.js refers to the block of code you have above which defines the combobox widget. In terms of supporting multiple jQuery version, it doesn't matter if this is included in-page as your example does, or as an external file as my example does. The anonymous function wrapper that you have (and all plugins should have), which stores the reference to jQuery is what makes this work. At the time those files are executed, jQuery points to the correct version, and the files stores a local reference to it as $. Later, when you can jQuery.noConflict(true), those files continue to hold their references, even though the global jQuery variable has changed. If you follow this pattern of invoking no conflict mode after loading all other files, you don't need to assign jQuery to a new variable, since all of your code will already have the necessary references. The benefit to this approach, is that you never end up with variable-specific names in your wrapper functions, and it's guaranteed to work with all existing plugins that were developed with this model, which is all official jQuery projects and likely any plugin that has thought about no conflict support.
One last thing: At the bottom of your script, you're referring to jQuery as $, but you're outside of the function wrapper that is storing the $ reference. If this is really two separate files in your app, make sure to include the wrapper in each file. If this is actually a single script as shown above, make sure to move the document ready block inside the wrapper.

jQuery Catcomplete with links

So, I'm trying to use HTML links in my catcomplete results, but jquery automatically transforms my html code into text, like on the image:
And my jQuery code is:
$( "#global-search" ).catcomplete({
delay: 0,
source: "globalsearch.php"
});
Please, dont say to me to use select: function( event, ui ) {
window.location.href = ui.item.value;
}, because it works only once when using ajax (I really don't know why, but it just doesn't work), and I asked some questions here yesterday asking how to fix it, and nobody helped me with it.
So, back with the html transformed into text, how can I add an html hyperlink to my results?
globalsearch.php:

Take a look at the Custom Data and Display example. You will see that they have replaced the _renderItem method with a custom one. You'll need to do the same thing to override how your items are displayed.
$('#global-search').data( "autocomplete" )._renderItem = function( ul, item ) {
return $( "<li>" )
.data( "item.autocomplete", item )
.append((item.link) ? "<a href='" + item.link + "'>" + item.label + "</a>" : "<a>" + item.label + "</a>" )
.appendTo( ul );
};
Without seeing the output of your globalsearch.php I can't tell you exactly how to set it up, but basically you'd want to add a link attribute to your returned JSON and if the link exists, print the anchor with the link as its href.
How you handle the selection links vs outside links is left as an exercise to the OP.

From the autocomplete widget documentation
Independent of the variant you use, the label is always treated as
text. If you want the label to be treated as html you can use Scott
González' html extension. The demos all focus on different variations
of the source option - look for one that matches your use case, and
check out the code.
Scott González' html extension is https://github.com/scottgonzalez/jquery-ui-extensions/blob/master/autocomplete/jquery.ui.autocomplete.html.js. I have also posted the code below.

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;
}
});
});
