JQuery _renderItem not being called - javascript

I am trying to create a custom ui-menu-item element using the _renderItem function but after may tries I can't get the function to even be called. The auto-complete is working but it is like the _renderItem function is not there. Here is my script scction
<script language="Javascript" type="text/javascript">
function split( val ) {
return val.split( /,\s*/ );
}
function extractLast( term ) {
return split( term ).pop();
}
$j(document).ready(function() { //START of ready function
$j( "#custom-report" )
.autocomplete({
source: function( request, response ) {
$j.getJSON( "<?=$this->url(array("controller"=>"report", "action"=>"custom-autocomplete"))?>", {
term: extractLast( request.term )
}, response );
},
search: function() {
//Place holder
},
focus: function (event, ui) {
// Prevent the default focus behavior.
event.preventDefault();
},
select: function( event, ui ) {
var terms = split( this.value );
terms.pop();
terms.push( ui.item.value );
this.value = terms.join( ", " );
return false;
}
}).data("autocomplete")._renderItem = function (ul, item) {
return $("<li />")
.data("item.autocomplete", item)
.append("This is the text")
.addClass("tip")
.attr("desc", "This is the description")
.appendTo(ul);
};
}); //END of ready function
</script>
Anyone have any idea why this is not working?

I ended up having to do this
$.ui.autocomplete.prototype._renderItem = function (ul, item) {
return $("<li></li>")
.data("item.autocomplete", item)
.addClass("tip ui-menu-item")
.append("<a>" + item.label + "</a>")
.attr("desc", item.description) /* This is the filed that started the whole thing */
.attr("role", "presentation")
.appendTo(ul);
};

It depends on jQuery UI version, in the newer version the object model is changed (see: http://jqueryui.com/upgrade-guide/1.10/#autocomplete).
The example on the jQuery UI site is based on jQuery UI 1.10.
1.9 and minor:
.data("autocomplete")._renderItem = function (ul, item) {
return $("<li />")
.data("item.autocomplete", item)
.append("This is the text")
.addClass("tip")
.attr("desc", "This is the description")
.appendTo(ul);
};
1.10 and next:
.data("ui-autocomplete")._renderItem = function (ul, item) {
return $("<li />")
.data("ui-autocomplete-item", item)
.append("This is the text")
.addClass("tip")
.attr("desc", "This is the description")
.appendTo(ul);
};

jQuery - Duplicate Fields & Autocomplete

I have a form with duplicate fields including autocomplete input.
The issue is : when i duplicate the fields, the autocomplete doesn't work on the new fields.
I spent time googling my issue and often it's a clone('true') issue, which i don't use already and still have the problem.
Can you help me please ? Thanks a lot !
I made a JSFiddle : https://jsfiddle.net/vqnaedvx/

JS Autocomplete :
$( function() {

value: "sizzlejs",

return false;

}
})
.autocomplete( "instance" )._renderItem = function( ul, item ) {
return $( "<li>" )
.append( "<div>" + item.label + "</div>" )
.appendTo( ul );
};
} );
you have 2 probs here:
1.Your code only for one input textfield. if u add more textfields, all value of textfields will have the same value. u need call autocomplete in foreach
2.After u press add input jquery not call autocomplete again(new input doesn't have autocomplete). So you need call it after new input added.
fixed here:
declare global function:
/**
* jQuery Autocomplete
*/
$( function() {
var projects = [
{
value: "jquery",
label: "jQuery"
},
{
value: "jquery-ui",
label: "jQuery UI"
},
{
value: "sizzlejs",
label: "Sizzle JS"
}
];
refreshAuto = function(){
$(".project-label").each(function(idx,ele){
var item = $(ele);
item.autocomplete({
minLength: 0,
source: projects,
focus: function( event, ui ) {
item.val( ui.item.label );
return false;
},
select: function( event, ui ) {
item.val( ui.item.label );
item.attr('id',ui.item.value);
return false;
}
})
.autocomplete( "instance" )._renderItem = function( ul, item ) {
return $( "<li>" )
.append( "<div>" + item.label + "</div>" )
.appendTo( ul );
};
});
}
refreshAuto(); // call to init once
} );
at "jQuery Multifield plugin" find '// Add section' add the line so:
// Add section
this.$elem.on('click',this.config.btnAdd,function(e){
e.preventDefault();
$this.cloneSection();
refreshAuto(); //call autocomplete new input
});
hope this help !

Lazy initialization of jquery UI autocomplete

I'd like to lazy initialize the source options of a jQueryUI autocomplete. I'm aware of the possibility to pass a function to the source option, but I want to delay the initialization until the user really starts using the autocomplete.
I tried waiting for the search event and then set the source option, but this has no effect.
var availableTags = [
"ActionScript",
"AppleScript",
"Scheme"
];
$("#searchFirstTransactionStateInfo_searchPartnerId").autocomplete({
source : [],
minLength: 0,
search: function( event, ui ) {
$(event.target).source = availableTags;
}
});
How can I delay setting the source option until the user starts using the UI element?
Note: I used a fixed array for simplicity. Finally I want to call an AJAX function.
Well, if you use a function as the source parameter, and let that function perform a get request (ajax ofcourse), it will actually only start making requests when you've typed something. As an example, open up your network tab and start typing in this UI example:
http://jqueryui.com/autocomplete/#multiple-remote
$(function() {
function split( val ) {
return val.split( /,\s*/ );
}
function extractLast( term ) {
return split( term ).pop();
}
$( "#birds" )
.autocomplete({
source: function( request, response ) {
$.getJSON( "search.php", {
term: extractLast( request.term )
}, response );
},
search: function() {
// custom minLength
var term = extractLast( this.value );
if ( term.length < 2 ) {
return false;
}
},
focus: function() {
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;
}
});
});

Custom Autocomplete with jquery

I am working on jquery autocomplete custom data and display.I want to display some static dropdown on keypress in textbox.when user select that list item i want to add it to textbox.
the code which i have tested is
$('#uinput').keyup(function() {
var val = $('#uinput').val();
if(val.length>1) { // check length
// handle successful DWR response
//alert(data);
var b=[{value: "jquery-ui",
label: "jQuery UI",}];
$('#uinput').autocomplete({source:b,
select: function( event, ui ) {
$( "#uinput" ).val( ui.item.label+"="+document.getElementById('uinput').value );
return false;
}
}).data("autocomplete")._renderItem = function( ul, item ) {
return $( "<li>" )
.data('item.autocomplete', item)
.append( "<a>" + item.label + "=" + document.getElementById('uinput').value + "</a>" )
.appendTo( ul );
};
} else {
$('#uinput').autocomplete([]); // clean
}
});
For reference what i want to do
custom autocomplete
I'm not exactly sure what you're trying to accomplish but I think I've put together this example that I think might help you
https://jsfiddle.net/mgxnxhs8/5/
here's my javascript
$(function () {
var availableTags = [{
label: "jQuery 1.9.1",
value: "http://code.jquery.com/jquery-1.9.1.js",
}, {
label: "jQuery 2.1.4",
value: "http://code.jquery.com/jquery-2.1.4.js",
}];
$('#uinput').autocomplete({
source: availableTags,
minLength: 0,
select: function (event, ui) {
$('#uoutput').val(ui.item.value);
return false;
}
}).focus(function () {
$(this).autocomplete("search");
});
});
The dropdown opens up when you enter the textbox and displays the "label" key of the tags. On Select(), it sets the value of another textbox to the "value" key of the selected tag.
Let me know if theres something I missed. Hope this helps

JqueryUI autocomplete returns wrong item on focus

I used JqueryUI on this project im working on.
When I focus on the next item in the list with the down arrow key, jqueryui returns the previous selected item
Here's a perfect working sample is here on jsFiddle
Here's the Jquery code
$( "#itemname" ).autocomplete({
source: function( request, response ) {
var matcher = new RegExp( "^" + $.ui.autocomplete.escapeRegex( request.term ), "i" );
response( $.grep( tags, function( item ){
return matcher.test( item );
}) );
},
//focus: function(event) { alert( event.type ); }
focus : function(event, ui) {
//alert( $(this).val() );
var item_name_this = $(this).val();
$('#properties_item_name').html(item_name_this);
}
});
focus: function (event, ui) {
var item_name_this = ui.item.value;
$('#properties_item_name').html(item_name_this);
}

Cannot set property '_renderItem' of undefined jQuery UI autocomplete with HTML

I'm using the following code to render my jQuery UI autocomplete items as HTML.
The items render correctly in the autocomplete control, but I keep getting this javascript error and can't move past it.
Firefox Could not convert JavaScript argument
Chrome Cannot set property '_renderItem' of undefined
donor.GetFriends(function (response) {
// setup message to friends search autocomplete
all_friends = [];
if (response) {
for (var i = 0; i < response.all.length - 1; i++) {
all_friends.push({
"label":"<img style='padding-top: 5px; width: 46px; height: 46px;' src='/uploads/profile-pictures/" +
response.all[i].image + "'/><br/><strong style='margin-left: 55px; margin-top: -40px; float:left;'>" +
response.all[i].firstname + " " + response.all[i].lastname + "</strong>",
"value":response.all[i].firstname + " " + response.all[i].lastname,
"id":response.all[i].user_id});
}
}
$('#msg-to').autocomplete({
source:all_friends,
select:function (event, ui) {
// set the id of the user to send a message to
mail_message_to_id = ui.item.id;
}
}).data("autocomplete")._renderItem = function (ul, item) {
return $("<li></li>")
.data("item.autocomplete", item)
.append($("<a></a>").html(item.label))
.appendTo(ul);
};
});
Not sure why it is throwing this error, or what I have to do to get past it...Any help is appreciated.
Since I just joined and can't comment on drcforbin's post above, I guess I have to add my own answer.
drcforbin is correct, although it is really a different problem than the one that the OP had. Anyone coming to this thread now is probably facing this issue due to the new version of jQuery UI just released. Certain naming conventions relating to autocomplete were deprecated in jQuery UI in v1.9 and have been completely removed in v1.10 (see http://jqueryui.com/upgrade-guide/1.10/#autocomplete).
What is confusing, however, is that they only mention the transition from the item.autocomplete data tag to ui-autocomplete-item, but the autocomplete data tag has also been renamed to ui-autocomplete. And it's even more confusing because the demos are still using the old syntax (and thus are broken).
The following is what needs to change in the _renderItem function for jQuery UI 1.10.0 in the Custom Data demo here: http://jqueryui.com/autocomplete/#custom-data
Original code:
.data( "autocomplete" )._renderItem = function( ul, item ) {
return $( "<li>" )
.data( "item.autocomplete", item )
.append( "<a>" + item.label + "<br>" + item.desc + "</a>" )
.appendTo( ul );
};
Fixed code:
.data( "ui-autocomplete" )._renderItem = function( ul, item ) {
return $( "<li>" )
.data( "ui-autocomplete-item", item )
.append( "<a>" + item.label + "<br>" + item.desc + "</a>" )
.appendTo( ul );
};
Note the changes for both autocomplete and item.autocomplete. I've verified that this works in my own projects.
I ran into the same problem...seems in later versions, it has to be .data("ui-autocomplete") instead of .data("autocomplete")
I know I'm late with my answer but if people in the future still don't get
.data( "ui-autocomplete-item", item )
to work then try this insted
$(document).ready(function(){
$('#search-id').autocomplete({
source:"search.php",
minLength:1,
create: function () {
$(this).data('ui-autocomplete')._renderItem = function (ul, item) {
return $('<li>')
.append( "<a>" + item.value + ' | ' + item.label + "</a>" )
.appendTo(ul);
};
}
})
});
It worked for me and I was having problem with the login funktion.. I could not login because it said
Uncaught TypeError: Cannot set property '_renderItem' of undefined
Hope this does help someone :)
/kahin
I'm using jquery 1.10.2 and it work using:
.data( "custom-catcomplete" )._renderItem = function( ul, item ) {
return $( "<li>" )
.data( "ui-autocomplete-item", item )
.append( "<a>" + item.label + "<br>" + item.desc + "</a>" )
.appendTo( ul );
};
And now, with jQuery-2.0.0, it's the name of your new module, but replacing the "." (dot) by the "-" (dash) :
jQuery.widget ('custom.catcomplete', jQuery.ui.autocomplete, {
'_renderMenu': function (ul, items) {
// some work here
}
});
$this.catcomplete({
// options
}).data('custom-catcomplete')._renderItem = function (ul, item) {}
Posting for the sake of any person who stumbles across this post.
This error will also manifest itself if you don't put the .autocomplete inside the document ready event.
The code below will fail:
<script type="text/javascript">
$('#msg-to').autocomplete({
source:all_friends,
select:function (event, ui) {
// set the id of the user to send a message to
mail_message_to_id = ui.item.id;
}
}).data("autocomplete")._renderItem = function (ul, item) {
return $("<li></li>")
.data("item.autocomplete", item)
.append($("<a></a>").html(item.label))
.appendTo(ul);
};
</script>
while the code below will work:
<script type="text/javascript">
$(function(){
$('#msg-to').autocomplete({
source:all_friends,
select:function (event, ui) {
// set the id of the user to send a message to
mail_message_to_id = ui.item.id;
}
}).data("autocomplete")._renderItem = function (ul, item) {
return $("<li></li>")
.data("item.autocomplete", item)
.append($("<a></a>").html(item.label))
.appendTo(ul);
};
});
</script>
Depending on the version of jquery ui you're using it will either be "autocomplete" or "ui-autocomplete", I made this update to the combobox plugin to fix the problem (~ln 78-85)
var autoComplete = input.data("ui-autocomplete");
if(typeof(autoComplete) == "undefined")
autoComplete = input.data("autocomplete");
autoComplete._renderItem = function(ul, item) {
