javascript Alert to confirm if value entered twice

I have a form:
// 10 times
<input type="text" name="cityname" class="autocompletecity">
<input type="text" name="cityID" class="autocompletecityID">
When I enter the city name, it autocompletes the city name and the cityID from database with this code:
<?php for ($i = 0; $i < 10; $i++) { /*in the field class add $i */ ?>
$(function() {
function log( message ) {
$( "<div>" ).text( message ).prependTo( "#log" );
$( "#log" ).scrollTop( 1 );
}
$( ".autocompletecity<?php echo $i ?>" ).autocomplete({
source: "/*path to json*/",
select: function( event, ui ) {
var item = ui.item;
if(item) {
$(".autocompletecityID<?php echo $i ?>").val(item.cityID);
$(this).val(item.value +' ' + item.country);
return false;
}
}
//code from J.D.
select: function( event, ui ) {
var item = ui.item;
if(item) {
$('input[name="cityID"]').each(function(index, element) {
var $element = $(element);
if ($element.value() == item.cityID) {
alert('This city has already been selected');
}
});
}
}
})
.autocomplete( "instance" )._renderItem = function( ul, item ) {
return $( "<li>" )
.append( "<a>" +item.value + " " +item.country + "</a>" )
.appendTo( ul );
};
});
<?php } ?>
After it autocompletes the cityID, I would like to show an alert box if same cityID has alredy been entered: Click OK to confirm or Cancel to clear the cityname and cityID with repeated entry.
I tried to search in the jqueryui, but no luck...
Thanks!!

Try this:
select: function( event, ui ) {
var item = ui.item;
if(item) {
$('input[name="cityID"]').each(function(index) {
var $element = $(this);
if ($element.value() == item.cityID) {
alert('This city has already been selected');
}
});
}
}

Struts 2 autocomplete onchange event

I am using struts2 autocompleter dojo tag and need to fire a javascript event onchange.
I have 2 questions.
1) How to fire onchange
2) dojo tags are not supported anymore. So what is the alternative?

Using Struts2-jQuery plugin's you can achieve it as below :
Please check out select part where i am calling javascript function(subinfo()) as per your need.
(function( $ ) {
var calltheData=false;
$.widget( "ui.combobox", {
_create: function() {
var self = this,
select = this.element.hide(),
selected = select.children( ":selected" ),
value = selected.val() ? selected.text() : "";
var input = this.input = $( "<input>" )
.insertAfter( select )
.val( value )
.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;
//jQueryOnchangeAutocompleter();
subinfo();
self._trigger( "selected", event, {
item: ui.item.option
});
},
change: function( event, ui ) {
if ( !ui.item ) {
var matcher = new RegExp( "^" + $.ui.autocomplete.escapeRegex( $(this).val() ) + "$", "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
$( this ).val( "" );
select.val( "" );
input.data( "autocomplete" ).term = "";
return false;
}
}
}
})
.addClass( "ui-widget ui-widget-content ui-corner-left" );
input.data( "autocomplete" )._renderItem = function( ul, item ) {
return $( "<li></li>" )
.data( "item.autocomplete", item )
.append( "<a>" + item.label + "</a>" )
.appendTo( ul );
};
this.button = $( "<button type='button'> </button>" )
.attr( "tabIndex", -1 )
.attr( "title", "Show All Items" )
.insertAfter( input )
.button({
icons: {
primary: "ui-icon-triangle-1-s"
},
text: false
})
.removeClass( "ui-corner-all" )
.addClass( "ui-corner-right ui-button-icon" )
.click(function() {
// close if already visible
if ( input.autocomplete( "widget" ).is( ":visible" ) ) {
input.autocomplete( "close" );
return;
}
// pass empty string as value to search for, displaying all results
input.autocomplete( "search", "" );
input.focus();
});
},
destroy: function() {
this.input.remove();
this.button.remove();
this.element.show();
$.Widget.prototype.destroy.call( this );
}
});
})( jQuery );
$( "#yourid" ).combobox();
You can write onchange as below:
<s:select list="yourdatlist" name="yourid"
id="yourid" listKey="wid" listValue="desc"
headerKey="-1" headerValue="" theme="simple" onchange="subinfo();">
</s:select>

Uncaught TypeError: undefined is not a function

I am newbie to js, I have copied a script from jqueryui.com for the dialog widget and pasted it in my Yii project, but I got an error: Uncaught TypeError: undefined is not a function, which is the function of $( "#dialog-form" ).dialog, so what is the error, and how I can fix it, here is the code:
$(function() {

Did you include something like
<script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.23/jquery-ui.min.js"></script>

the problem is solved, its because I loaded a default jquery package instead of the customized Jquery package that contains the dialog widget.

Dynamic number of autocomplete search box with values

In my setup, I have two input boxes , book name and book price. Book Name is autocomplete. I am stuck while I tried to set value for price based on selection. For example if I select ajax in the autocomplete "1003" should be selected in book price.
jQuery code below:
$(function() {
var projects = [
{
"label": "ajax",
"value": "1003",
"desc": "foriegn"
},
{
"label": "jquery",
"value": "1000",
"desc": "dd"
},
{
"label": "wordpress theme",
"value": "1000",
"desc": "h"
},
{
"label": "xml",
"value": "1000",
"desc": "j"
} ];
$( "#project" ).autocomplete({
minLength: 0,
source: projects,
focus: function( event, ui ) {
$( "#project" ).val( ui.item.label );
return false;
},
select: function( event, ui ) {
$( "#project" ).val( ui.item.label );
$( "#project-id" ).val( ui.item.value );
$( "#project-description" ).val( ui.item.value );
$( "#project-icon" ).attr( "src", "images/" + ui.item.icon );
return false;
}
})
.data( "ui-autocomplete" )._renderItem = function( ul, item ) {
return $( "<li>" )
.append( "<a>" + item.label + "</a>" )
.appendTo( ul );
};
/*Add Row feature starts here*/
$("#addButton");
var counter = 13;
$("#addButton").click(function () {
var newTextBoxDiv = $(document.createElement('div'))
.attr("id", 'TextBoxDiv' + counter);
var roleInput = $('<input/>',{
type:'text',
placeholder:'Role',
name:'Role'+counter,
id:'project-description' + counter
});
var searchInput = $('<input/>',{
type:'text',
placeholder:'search',
name:'search'+counter,
id:'project' + counter
});
var hidd=$('<input/>',{
type:'hidden',
name:'searchhid'+counter,
id:'project-id' + counter
});
newTextBoxDiv.append(roleInput).append(searchInput).append(hidd);
newTextBoxDiv.appendTo("#TextBoxesGroup");
$('#project' + counter).autocomplete({
minLength: 0,
source: projects,
focus: function( event, ui ) {
$( "#project" + counter ).val( ui.item.label );
return false;
},
select: function( event, ui ) {
$( "#project" + counter ).val( ui.item.label );
$( "#project-id" + counter).val( ui.item.value );
$( "#project-description" + counter).val( ui.item.value );
$( "#project-icon" + counter).attr( "src", "images/" + ui.item.icon );
return false;
}
});
counter++;
});
/*Add row feature ends here*/
});
html is below
<div id="project-label"></div>
<input id="project" />
<input type="hidden" id="project-id" />
<input type="text" disabled="disabled" id="project-description"></p>
<div id='TextBoxesGroup'>
<div id="TextBoxDiv1" class="form-inline control-group">
</div>
</div>
<input type='button' value='Add' id='addButton' />
I am not sure why autocomplete selection isnt working for the dynamically added input boxes. Any help will be highly appreciated

jquery Ui Combobox Error on Chrome / IE 7

For some reason the combobox button aint showing on IE or Chrome, so i end up with just a textbox. anyone figured out how to solve?
Using latest jquery/jqueryui/combobox version.
Heres my edited version of ui.combobox (specially coz original version doesnt give an id to the new element), also theres a fix for combobox size:
(function( $ ) {
$.widget( "ui.combobox", {
_create: function() {
var self = this,
id = this.element.attr("id"),
select = this.element,
theWidth = select.width(),
selected = select.children( ":selected" ),
value = selected.val() ? selected.text() : "";
select.hide();
//fix, doesnt let the element beign too short.
if(theWidth < 110) {
theWidth = 110;
}
var input = $('<input id="' + id + '-combo" style="width: ' + theWidth + 'px;">')
//.insertAfter( select )
.val( value )
.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 {
id: this.value,
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;
self._trigger( "selected", event, {
item: ui.item.option
});
},
change: function( event, ui ) {
if ( !ui.item ) {
var matcher = new RegExp( "^" + $.ui.autocomplete.escapeRegex( $(this).val() ) + "$", "i" ),
valid = false;
select.children( "option" ).each(function() {
if ( this.value.match( matcher ) ) {
this.selected = valid = true;
return false;
}
});
if ( !valid ) {
// remove invalid value, as it didn't match anything
$( this ).val( "" );
select.val( "" );
return false;
}
}
}
})
.addClass( "ui-widget ui-widget-content ui-corner-left" );
var span = $('<span style="white-space: nowrap;"></span>')
.append(input).insertAfter( select );
input.data( "autocomplete" )._renderItem = function( ul, item ) {
return $( "<li></li>" )
.data( "item.autocomplete", item )
.append( "<a>" + item.label + "</a>" )
.appendTo( ul );
};

.attr( "tabIndex", -1 )
.attr( "title", "Mostrar Todos os itens" )
.insertAfter( input )
.button({

},
text: false
})
.removeClass( "ui-corner-all" )
.addClass( "ui-corner-right ui-button-icon" )
.click(function() {
// close if already visible
if ( input.autocomplete( "widget" ).is( ":visible" ) ) {
input.autocomplete( "close" );
return;
}
// pass empty string as value to search for, displaying all results
input.autocomplete( "search", "" );
input.focus();
});
}
});
})( jQuery );

Heres the fix my friend pointed. This version of ui.combobox got auto width, and few fixes i found # web. works on ie also.
(function( $ ) {
$.widget( "ui.combobox", {

id = this.element.attr("id"),
select = this.element,
theWidth = select.width(),
selected = select.children( ":selected" ),
value = selected.val() ? selected.text() : "";
select.hide();
//fix, doesnt let the element beign too short.
if(theWidth < 110) {
theWidth = 110;
}
var input = $('<input id="' + id + '-combo" style="width: ' + theWidth + 'px;">')
//.insertAfter( select )
.val( value )
.autocomplete({
delay: 0,
