I am wanting to run a function of the jQuery autocomplete below only returns 1 result. I am not sure how to check that there is only 1 result in the list.
Please help.
$(function() {
function log(message) {
$("<div>").text(message).prependTo("#log");
$("#log").scrollTop(0);
}
$("#inputBox2").autocomplete({
source: "searchsalonproduct.php",
cacheLength: 0,
minLength: 1,
select: function(event, ui) {
addcharge(ui.item.id);
return false;
}
}).data("ui-autocomplete")._renderItem = function(ul, item) {
return $("<li></li>")
.data("item.autocomplete", item)
.append("<a>" + item.label + "</a>")
.appendTo(ul);
};
});
Use the response event to check. The results found are stored in ui.content (ui is an argument in the event handler).
$("#inputBox2").autocomplete({
source: "searchsalonproduct.php",
cacheLength: 0,
minLength: 1,
select: function(event, ui) {
addcharge(ui.item.id);
return false;
},
response: function(event, ui) {
if(ui.content.length === 1) {
//do stuff
}
}
}).data("ui-autocomplete")._renderItem = function(ul, item) {
return $("<li></li>")
.data("item.autocomplete", item)
.append("<a>" + item.label + "</a>")
.appendTo(ul);
};

So far I've used Jquery autocomplete for backend php. But I want to use jquery auto complete to fetch records from couchdb. Can anyone please help me.
Or is there any other way to achieve autocomplete with couchDB
function log( message ) {
$( "<div>" ).text( message ).prependTo( "#log" );
$( "#log" ).scrollTop( 0 );
}
$("#search_name").autocomplete({
source: function( request, response ) {
$.couch.db("db1").view("Views/testPatients", {
success: function(data) {
response(data.rows);
},
error: function(status) {
console.log(status);
},
key: request.term
});
},
minLength: 3,
focus: function(event, ui) {
console.log(ui.item.key);
$("#search_name").val(ui.item.key);
return false;
},
select: function( event, ui ) {
$("#search_name").val(ui.item.key);
return false;
},
open: function() {
$( this ).removeClass( "ui-corner-all" ).addClass( "ui-corner-top" );
},
close: function() {
$( this ).removeClass( "ui-corner-top" ).addClass( "ui-corner-all" );
}
}).
data("uiAutocomplete")._renderItem = function(ul, item) {
return $("<li></li>")
.data("item.autocomplete", item)
.append("<a>" + item.key + "</a>")
.appendTo(ul);
};
I am using a jquery ui autocomplete. when the user types in their own value, rather than selecting an item from the list, the textbox clears. This is ok (I don't want the user to be able to enter their own values) except if the user types in a value that does exist on the list.
I tried using the autoSelect plugin as detailed in this post, but it is not working - I added the plugin but when I type in a value that IS on the list and hit tab, I get the same results as before - the textbox clears.
Here is my autocomplete:
$(function () {
$('[id$="txtDocType').autocomplete({
source: function (request, response) {
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "/MyPage.aspx/myFunction",
data: "{'prefixText':'" + request.term.toLowerCase() + "', 'ddvId':'" + this.element.data('autocomplete') + "'}",
dataType: "json",
success: function (data) {
response(data.d);
},
error: function (result) { }
});
},
minlength: 1,
select: function (event, ui) {
$('#divOtherFields input[type=text], input[type=password]').prop("disabled", false).removeClass("disabled");
$('[id$="btnSaveNext"],[id$="btnSaveClose"]').prop("disabled", false);
$('[id$="txtReceiptDate"]').datepicker("setDate", new Date());
}
});
});
Here is the plugin:
(function( $ ) {
$.ui.autocomplete.prototype.options.autoSelect = true;
$( ".ui-autocomplete-input" ).on( "blur", function( event ) {
var autocomplete = $( this ).data( "autocomplete" );
if ( !autocomplete.options.autoSelect || autocomplete.selectedItem ) { return; }
var matcher = new RegExp( "^" + $.ui.autocomplete.escapeRegex( $(this).val() ) + "$", "i" );
autocomplete.widget().children( ".ui-menu-item" ).each(function() {
var item = $( this ).data( "item.autocomplete" );
if ( matcher.test( item.label || item.value || item ) ) {
autocomplete.selectedItem = item;
return false;
}
});
if ( autocomplete.selectedItem ) {
autocomplete._trigger( "select", event, { item: autocomplete.selectedItem } );
}
});
}( jQuery ));
I set a breakpoint in the plugin on this line - "$( ".ui-autocomplete-input" ).on( "blur", function( event )" and the breakpoint was hit, yet the code would not step through. When I set a breakpoint to this line - "var autocomplete = $( this ).data( "autocomplete" );" the breakpoint was NOT hit.
Any ideas? I am at my wits end with this.
I solved this by making a couple of tweaks to the autoSelect plugin. Here is the code that eventually worked for me:
$(".ui-autocomplete-input").bind("focusout", function (event) {
var autocomplete = $(this).data("ui-autocomplete");
if (!autocomplete.options.autoSelect || autocomplete.selectedItem) { return; }
var matcher = new RegExp("^" + $.ui.autocomplete.escapeRegex($(this).val()) + "$", "i");
autocomplete.widget().children(".ui-menu-item").each(function () {
var item = $(this).data("ui-autocomplete-item");
if (matcher.test(item.label || item.value || item)) {
autocomplete.selectedItem = item;
return false;
}
});
if (autocomplete.selectedItem) {
autocomplete._trigger("select", event, { item: autocomplete.selectedItem });
}
});
I used the focus event to set the first value to a hidden variable. The same hidden variable also got updated in the select event. And then this was the hidden variable which I posted to the ajax call.
Why I did not use focus to set the value in the autocomplete input box, was because doing so populated the autocomplete input box even while I was typing in this box.
focus: function (event, ui) {
if($("#streetid")) $("#streetid").val(ui.item.label); //this was my hidden variable
}
},
I have the following code. It generates no js errors. Can't get the autocomplete to display any results:
$(function() {
$.ajax({
url: "data.xml",
dataType: "xml",
cache: false,
success: function (xmlResponse) {
var data_results = $("Entry", xmlResponse).map(function () {
return {
var1: $.trim($("Partno", this).text()),
var2: $.trim($("Description", this).text()),
var3: $.trim($("SapCode", this).text()),
var4: $("Title", this).text(),
var5: $.trim($("File", this).text()),
var6: $.trim($("ItemID", this).text())
};
}).get();
$("#searchresults").autocomplete({
source: data_results,
minLength: 3,
select: function (event, ui) {
...
}
}).data( "autocomplete" )._renderItem = function( ul, item ) {
return $( "<li></li>" ).data("item.autocomplete", item)
.append( "<a>" + item.var1 + "<br>" + item.var2 + "</a>")
.appendTo( ul );
};
}
});
Any ideas what I might be missing? Thanks in advance.
It seems that .data('autocomplete') is now .data('ui-autocomplete').

By default, autocomplete expects your source array to contain objects with either a label property, a value property, or both.
With that in mind you have two options:
Add a label or value property to your source objects when you process the array from your AJAX call:
var data_results = $("Entry", xmlResponse).map(function () {
return {
var1: $.trim($("Partno", this).text()),
var2: $.trim($("Description", this).text()),
var3: $.trim($("SapCode", this).text()),
var4: $("Title", this).text(),
var5: $.trim($("File", this).text()),
var6: $.trim($("ItemID", this).text()),
value: $.trim($("Description", this).text())
};
}).get();
The value you assign will be used on focus, select, and to search on.
Change the source function to perform custom filtering logic:
$("#searchresults").autocomplete({
source: function (request, response) {
var matcher = new RegExp($.ui.autocomplete.escapeRegex(request.term), "i");
response($.grep(data, function (value) {
return matcher.test(value.var1) ||
matcher.test(value.var2);
/* etc., continue with whatever parts of the object you want */
}));
},
minLength: 3,
select: function (event, ui) {
event.preventDefault();
this.value = ui.var1 + ui.var2;
},
focus: function (event, ui) {
event.preventDefault();
this.value = ui.var1 + ui.var2;
}
}).data( "autocomplete" )._renderItem = function( ul, item ) {
return $( "<li></li>" ).data("item.autocomplete", item)
.append( "<a>" + item.var1 + "<br>" + item.var2 + "</a>")
.appendTo( ul );
};
Note that with this strategy you have to implement custom select and focus logic.
I am using the jQueryUI autocomplete, have used it many times before, but I now have a more complex requirement.
I have a variable amount of Autocomplete fields to setup, using a JSON datasource and want to use an $().each to set these up. The problem appears to be the data: property of the AJAX call is always defaulting to values the final Autocomplete I setup.
$('[id$=CheckMethod]').each(function(index) {
if ($(this).val() === 'List') {
fieldToSetup = ($(this).attr('id').replace('txt',''));
fieldToSetup = left(fieldToSetup,(fieldToSetup.length - 11));
alert(fieldToSetup);
$('#txt' + fieldToSetup + 'CodeRoom' + escape(inRoomID)).autocomplete({
source: function (request, response) {
var src,
arrayData;
src = 'AJAXCheckCode.asp?actionType=List&GUID=' + $('#txtGUID').val();
$.ajax({
url: src,
datatype: 'json',
data: 'inCode=' + request.term + '&inType=' + $(this).attr('id'),
success: function (outData) {
arrayData = $.parseJSON(outData);
response($.map(arrayData, function (item) {
var theLabel = (item.Notes.length > 0) ? item.TheCode + ' - ' + item.Notes : item.TheCode;
return {
label: theLabel,
value: item.TheCode
};
}));
}
});
},
minLength: 1,
open: function (event, ui) {
$(".ui-slider-handle ui-state-default ui-corner-all").hide();
$(".ui-autocomplete.ui-menu").width(400);
$(".ui-autocomplete.ui-menu").css('z-index', 1000);
},
close: function (event, ui) {
$(".ui-slider-handle ui-state-default ui-corner-all").show();
},
focus: function (event, ui) {
return false;
},
select: function (event, ui) {},
search: function (event, ui) {
}
});
}
});//each CheckMethod
This code results in the 1st Autocomplete field using the inType parameter from the last field setup.
I'd rather not code for a maximum of 4 x 6 Autocomplete fileds and am trying to create one function to setup all the fields, is this possible?
Therefore my AJAX URL for my 1st Autocomplete looks like this
http://foo.com/AJAXCheckCode.asp?actionType=List&GUID={838138D6-A329-40F1-924B-58965842ECF8}&inCode=es&inType=A3&_=1335875408670
when "inType" should actually be A2, not A3 which is the last item of the outer $.each()
Hope this makes some sense!
Solved in the end by adding a class to the text box and then using live() on any text box with the given class that hasn't been bound before...works a charm
$('.foo:not(.ui-autocomplete-input)').live('focus', function(){
var fieldToReSource = ($(this).attr('id').replace('txt',''));
fieldToReSource = left(fieldToReSource,(fieldToReSource.length - 5));
$(this).autocomplete({
source: function (request, response) {
var src,
arrayData;
src = 'AJAXCheckCode.asp?inType=' + fieldToReSource + '&actionType=List&GUID=' + $('#txtGUID').val();
$.ajax({
url: src,
datatype: 'json',
data: 'inCode=' + request.term,
success: function (outData) {
arrayData = $.parseJSON(outData);
response($.map(arrayData, function (item) {
var theLabel = (item.Notes.length > 0) ? item.TheCode + ' - ' + item.Notes : item.TheCode;
return {
label: theLabel,
value: item.TheCode
};
}));
}
});
},
minLength: 1,
open: function (event, ui) {
$(".ui-slider-handle ui-state-default ui-corner-all").hide();

return false;

I am using jquery ui 1.7.2 alongwith jquery 1.3.2
The following script is causing drop event to be triggered twice.. I tried a lot of time but not able to figure out why?
any suggestions to fix this code
$("document").ready(function () {
$(".draggable").draggable({
revert: "invalid",
helper: "clone",
connectToSortable: ".column"
});
$(".column").droppable({
accept: ".draggable",
drop: function (event, ui) {
debugger;
var ordinalNo = 1;
$(".column .contentObject").each(function () {
ordinalNo = ordinalNo + 1;
});
var objectId = guidGenerator() + '_' + ordinalNo;
var objectType;
var contentObjContent = "<div id=\"" + objectId + "\" ><h2>[<span class=\"ordinal\"></span>] ";
if (event.srcElement.id === "tableobj") {
objectType = tableSource;
}
else if (event.srcElement.id === "chartobj") {
objectType = chartSource;
}
else if (event.srcElement.id === "textobj") {
objectType = textSource;
}
$.ajax({
url: "/ContentBuilder/ContentObject",
data: {
viewObjectId: objectId,
contentObjectId: null,
contentObjectTypeId: objectType,
contentObjSourceId: null,
ordinal: ordinalNo
},
type: "POST",
success: function (data) {
contentObjContent = data;
}
});
}
});
$(".column").sortable({
connectWith: '.column',
handle: 'h2',
cursor: 'move',
placeholder: 'placeholder',
forcePlaceholderSize: true,
opacity: 0.4,
update: function (event, ui) {
changeOrdinal();
if (event.srcElement.id.length <= 0) {
updateObjectOrdinals();
}
}
}).disableSelection();
$(".tablecolumn").sortable({
connectWith: '.tablecolumn',
handle: 'h2',
cursor: 'move',
placeholder: 'placeholder',
forcePlaceholderSize: true,
opacity: 0.4,
update: function (event, ui) {
changeColumnOrdinal();
}
}).disableSelection();
});
becouse you use dropable AND sortable on the same selector $(".column"). I think both triggering a drop.
