What's wrong with select2 4.x optgroup? - jquery-select2

"optgroup" works well in 3.x versions, but in versions starts all of 4.x I have only "No results found" in dropdown. What's wrong? Official haven't issue about this bug.
My jade:
select.select-js(style="width: 100%")
option
optgroup(label="lbl1")
option(value='0') Opt Text
option(value='1') Opt Text
option(value='2') Opt Text
option(value='3') Opt Text
optgroup(label="lbl2")
option(value='4') Opt Text
option(value='5') Opt Text
option(value='6') Opt Text
option(value='7') Opt Text
option 123
And JS:
function LoadSelect2 () {
$('.select-js').select2({
minimumResultsForSearch: Infinity,
maximumInputLength: 0,
theme: "vesta",
templateResult: formatRes,
width: 'resolve',
placeholder: function () {
$(this).data('placeholder');
}
});
};

placeholder: function () {
$(this).data('placeholder');
}
Must to delete this

tablesorter -- pager_output variables shared across multiple tables

Using the latest jquery / tablesorter / widgets (as of Jan 18, 2016), using the pager widget, set pager_output to anything you want, so long as you include {totalRows}. Create two or more trivial tables with different id's and attach tablesorter to each id. Make sure the tables have a different number of rows. The pager will show the totalRows of the last-encountered table for every table rather than the appropriate number for each table.
The same is true for {filteredRows} when you including filtering.
It works fine for me... make sure that the code isn't pointing to the same pager container for both tables (demo)
$('table').each(function(){
$(this).tablesorter({
theme: "bootstrap",
widthFixed: true,
headerTemplate: '{content} {icon}',
widgets: ["uitheme", "filter", "zebra"],
})
.tablesorterPager({
container: '.' + this.id,
cssGoto: ".pagenum",
output: '{startRow} - {endRow} / {filteredRows} ({totalRows})'
});
});
Update: Oops, here is a demo using the pager widget
$('table').each(function(){
$(this).tablesorter({ debug: true,
theme: "bootstrap",
widthFixed: true,
headerTemplate: '{content} {icon}',
widgets: ["uitheme", "filter", "zebra", 'pager'],
widgetOptions: {
pager_selectors : {
container : '.' + this.id
},
pager_output: '{startRow} - {endRow} / {filteredRows} ({totalRows})'
}
});
});

Select2 AJAX doesn't update when changed programatically

I have a Select2 that fetches its data remotely, but I would also like to set its value programatically. When trying to change it programatically, it updates the value of the select, and Select2 notices the change, but it doesn't update its label.
https://jsfiddle.net/Glutnix/ut6xLnuq/
$('#set-email-manually').click(function(e) {
e.preventDefault();
// THIS DOESN'T WORK PROPERLY!?
$('#user-email-address') // Select2 select box
.empty()
.append('<option selected value="test#test.com">test#test.com</option>');
$('#user-email-address').trigger('change');
});
I've tried a lot of different things, but I can't get it going. I suspect it might be a bug, so have filed an issue on the project.
reading the docs I think maybe you are setting the options in the wrong way, you may use
data: {}
instead of
data, {}
and set the options included inside {} separated by "," like this:
{
option1: value1,
option2: value2
}
so I have changed this part of your code:
$('#user-email-address').select2('data', {
id: 'test#test.com',
label: 'test#test.com'
});
to:
$('#user-email-address').select2({'data': {
id: 'test#test.com',
label: 'test#test.com'
}
});
and the label is updating now.
updated fiddle
hope it helps.
Edit:
I correct myself, it seems like you can pass the data the way you were doing data,{}
the problem is with the data template..
reading the docs again it seems that the data template should be {id, text} while your ajax result is {id, email}, the set manual section does not work since it tries to return the email from an object of {id, text} with no email. so you either need to change your format selection function to return the text as well instead of email only or remap the ajax result.
I prefer remapping the ajax results and go the standard way since this will make your placeholder work as well which is not working at the moment because the placeholder template is {id,text} also it seems.
so I have changed this part of your code:
processResults: function(data, params) {
var payload = {
results: $.map(data, function(item) {
return { id: item.email, text: item.email };
})
};
return payload;
}
and removed these since they are not needed anymore:
templateResult: function(result) {
return result.email;
},
templateSelection: function(selection) {
return selection.email;
}
updated fiddle: updated fiddle
For me, without AJAX worked like this:
var select = $('.user-email-address');
var option = $('<option></option>').
attr('selected', true).
text(event.target.value).
val(event.target.id);
/* insert the option (which is already 'selected'!) into the select */
option.appendTo(select);
/* Let select2 do whatever it likes with this */
select.trigger('change');
Kevin-Brown on GitHub replied and said:
The issue is that your templating methods are not falling back to text if email is not specified. The data objects being passed in should have the text of the <option> tag in the text property.
It turns out the result parameter to these two methods have more data in them than just the AJAX response!
templateResult: function(result) {
console.log('templateResult', result);
return result.email || result.text;
},
templateSelection: function(selection) {
console.log('templateSelection', selection);
return selection.email || selection.id;
},
Here's the fully functional updated fiddle.

ASP.Net MVC validation not working with Bootstrap Select Picker

I've issue with ASP.NET MVC validation not working with Bootstrap Select Picker, If I remove the selectpicker class from dropdown list the validation working fine and if I added it the validation not working , Any help please
The MVC Code :
#Html.DropDownListFor(m => m.SelectedLocationID, Model.lstOfLocations, "Select Delivery Location", new { #class = " selectpicker", #placeholder = "" })
#Html.ValidationMessageFor(m => m.SelectedLocationID)
The Jquery Code With Valida-min.js
$(".SearchForm").validate({
ignore: ':not(select:hidden, input:visible, textarea:visible)',
rules: {
SelectedLocationID: {
required: true
}
},
errorPlacement: function (error, element) {
if ($(element).is('Select Delivery Location')) {
element.next().after(error);
} else {
error.insertAfter(element);
}
}
})
Thanks
I stumbled upon this question while searching for fix for same issue.
The problem arises from fact, that Bootstrap hides original select element and creates it's own elements to handle UI for dropdown list. In the meantime, jQuery validation by default ignores invisible fields.
I fixed this with workaround which combines changing validation ignore list and finding parent form. Final code snippet in my case looks like this
if ($(".selectpicker")[0]) {
$(".selectpicker").selectpicker();
$('.selectpicker').parents('form:first').validate().settings.ignore = ':not(select:hidden, input:visible, textarea:visible)';
}
There still could be potential issues, but for my needs this solution works good enough.
The problem is caused by the display:none property given from bootstrap select skin to the original select (jQuery validate ignores hidden fields).
It could be avoided working only with CSS keeping back visible the original select but giving it some properties to avoid visibility
select.bs-select-hidden, select.selectpicker
{
display:block !important; opacity:0; height:1px; width:1px;
}
I guess, editing of bootstrap-select.js may solve this issue permanently.
I have tried something like this:
$(document)
.data('keycount', 0)
.on('keydown.bs.select', '.bootstrap-select [data-toggle=dropdown], .bootstrap-select [role="listbox"], .bs-searchbox input', Selectpicker.prototype.keydown)
.on('focusin.modal', '.bootstrap-select [data-toggle=dropdown], .bootstrap-select [role="listbox"], .bs-searchbox input', function (e) {
//Validation handler: Kartik
var $thisParent = $(this).parent(".bootstrap-select");
if ($thisParent.find("ul").find("li:first").hasClass("selected")) {
if ($thisParent.next("span").length > 0)
$thisParent.next("span").css("display", "block");
}
else {
if ($thisParent.next("span").length > 0)
$thisParent.next("span").css("display", "none");
}
e.stopPropagation();
});
Its working fine to me.

Pass data to a html page opened in jQuery UI dialog

I have succeeded in opening a html page in a jQuery dialogbox. I have also passed a data called 'vendorid' to it, but do not know how to retrieve it in the html page that opens.
$('#btnShowSupplierStats').click(function () {
showUrlInDialog('../supplierstats.htm?vendorId=' + $(this).attr('vendorId')); return false;
//showUrlInDialog('../Default2.aspx'); return false;
});
function showUrlInDialog(url) {
var vid = $(this).attr('vendorId')
var tag = $("<div id='statsDiv' vid ='"+ vid +"'></div>");
$.ajax({
url: url,
success: function (data) {
tag.html(data).dialog({ show: "fadein", hide: "fadeout",
modal: true, minHeight: 550, minWidth: 800, autoOpen: false,
close: function (event, ui) { $(this).remove(); }, buttons: [{
text: "Close", click: function () { $(this).dialog('close');
return false; } }] }).data("vendorid", vid).dialog('open');
return false;
}
});
}
UPDATE: The answer from Farrukh would do this job ( i.e. second option he mentioned, since I am using a 100% client-side approach). But I did not store the data to be passed in a hiddent field. Instead I used the following approach which also works always:
When you are about to open the dialog through jQuery, just before this, set the attribute for the button which is the opener of dialog. In my case, I set an attribute called 'vendorid' on this button. Let's say the id of the opener button is 'btnOpenVendorDialog'. So need to use the following code.
$('#btnOpenVendorDialog').attr('vendorid', 'Vendor1234');
//open your dialog here ....
2.Then, in the html page that opens in dialog window, I can easily retrieve this attribute without any problems.
var vid = $('#btnOpenVendorDialog').attr('vendorid');
THAT's IT. YOU ARE ALL READY TO do whatever you want with this passed data.
There are two ways to do this:
Use server side and get the passed data in post or get(in your case vendor ID is get) and use it to populate a hidden element or data-vendorID attribute of any available element.
If you are using javascript then data vendorID that you have passed as vid is available after success function so place it in as a hidden input field or place it as a data-vendor-id on one of the other DOM elements and access it from there.

Lift - Autocomplete with Ajax Submission

I would like to use an autocomplete with ajax. So my goal is to have:
When the user types something in the text field, some suggestions provided by the server appear (I have to find suggestions in a database)
When the user presses "enter", clicks somewhere else than in the autocomplete box, or when he/she selects a suggestion, the string in the textfield is sent to the server.
I first tried to use the autocomplete widget provided by lift but I faced three problems:
it is meant to be an extended select, that is to say you can originally only submit suggested values.
it is not meant to be used with ajax.
it gets buggy when combined with WiringUI.
So, my question is: How can I combine jquery autocomplete and interact with the server in lift. I think I should use some callbacks but I don't master them.
Thanks in advance.
UPDATE Here is a first implementation I tried but the callback doesn't work:
private def update_source(current: String, limit: Int) = {
val results = if (current.length == 0) Nil else /* generate list of results */
new JsCmd{def toJsCmd = if(results.nonEmpty) results.mkString("[\"", "\", \"", "\"]") else "[]" }
}
def render = {
val id = "my-autocomplete"
val cb = SHtml.ajaxCall(JsRaw("request"), update_source(_, 4))
val script = Script(new JsCmd{
def toJsCmd = "$(function() {"+
"$(\"#"+id+"\").autocomplete({ "+
"autocomplete: on, "+
"source: function(request, response) {"+
"response("+cb._2.toJsCmd + ");" +
"}"+
"})});"
})
<head><script charset="utf-8"> {script} </script></head> ++
<span id={id}> {SHtml.ajaxText(init, s=>{ /*set cell to value s*/; Noop}) } </span>
}
So my idea was:
to get the selected result via an SHtml.ajaxText field which would be wraped into an autocomplete field
to update the autocomplete suggestions using a javascript function
Here's what you need to do.
1) Make sure you are using Lift 2.5-SNAPSHOT (this is doable in earlier versions, but it's more difficult)
2) In the snippet you use to render the page, use SHtml.ajaxCall (in particular, you probably want this version: https://github.com/lift/framework/blob/master/web/webkit/src/main/scala/net/liftweb/http/SHtml.scala#L170) which will allow you to register a server side function that accepts your search term and return a JSON response containing the completions. You will also register some action to occur on the JSON response with the JsContext.
3) The ajaxCall above will return a JsExp object which will result in the ajax request when it's invoked. Embed it within a javascript function on the page using your snippet.
4) Wire them up with some client side JS.
Update - Some code to help you out. It can definitely be done more succinctly with Lift 2.5, but due to some inconsistencies in 2.4 I ended up rolling my own ajaxCall like function. S.fmapFunc registers the function on the server side and the function body makes a Lift ajax call from the client, then invokes the res function (which comes from jQuery autocomplete) on the JSON response.
My jQuery plugin to "activate" the text input
(function($) {
$.fn.initAssignment = function() {
return this.autocomplete({
autoFocus: true,
source: function(req, res) {
search(req.term, res);
},
select: function(event, ui) {
assign(ui.item.value, function(data){
eval(data);
});
event.preventDefault();
$(this).val("");
},
focus: function(event, ui) {
event.preventDefault();
}
});
}
})(jQuery);
My Scala code that results in the javascript search function:
def autoCompleteJs = JsRaw("""
function search(term, res) {
""" +
(S.fmapFunc(S.contextFuncBuilder(SFuncHolder({ terms: String =>
val _candidates =
if(terms != null && terms.trim() != "")
assigneeCandidates(terms)
else
Nil
JsonResponse(JArray(_candidates map { c => c.toJson }))
})))
({ name =>
"liftAjax.lift_ajaxHandler('" + name
})) +
"=' + encodeURIComponent(term), " +
"function(data){ res(data); }" +
", null, 'json');" +
"""
}
""")
Update 2 - To add the function above to your page, use a CssSelector transform similar to the one below. The >* means append to anything that already exists within the matched script element. I've got other functions I've defined on that page, and this adds the search function to them.
"script >*" #> autoCompleteJs
You can view source to verify that it exists on the page and can be called just like any other JS function.
With the help of Dave Whittaker, here is the solution I came with.
I had to change some behaviors to get:
the desired text (from autocomplete or not) in an ajaxText element
the possibility to have multiple autocomplete forms on same page
submit answer on ajaxText before blurring when something is selected in autocomplete suggestions.
Scala part
private def getSugggestions(current: String, limit: Int):List[String] = {
/* returns list of suggestions */
}
private def autoCompleteJs = AnonFunc("term, res",JsRaw(
(S.fmapFunc(S.contextFuncBuilder(SFuncHolder({ terms: String =>
val _candidates =
if(terms != null && terms.trim() != "")
getSugggestions(terms, 5)
else
Nil
JsonResponse(JArray(_candidates map { c => JString(c)/*.toJson*/ }))
})))
({ name =>
"liftAjax.lift_ajaxHandler('" + name
})) +
"=' + encodeURIComponent(term), " +
"function(data){ res(data); }" +
", null, 'json');"))
def xml = {
val id = "myId" //possibility to have multiple autocomplete fields on same page
Script(OnLoad(JsRaw("jQuery('#"+id+"').createAutocompleteField("+autoCompleteJs.toJsCmd+")"))) ++
SHtml.ajaxText(cell.get, s=>{ cell.set(s); SearchMenu.recomputeResults; Noop}, "id" -> id)
}
Script to insert into page header:
(function($) {
$.fn.createAutocompleteField = function(search) {
return this.autocomplete({
autoFocus: true,
source: function(req, res) {
search(req.term, res);
},
select: function(event, ui) {
$(this).val(ui.item.value);
$(this).blur();
},
focus: function(event, ui) {
event.preventDefault();
}
});
}
})(jQuery);
Note: I accepted Dave's answer, mine is just to provide a complete answer for my purpose
