Basically I have implemented a dropdown using select2, and I wired it up with ajax. That all works alright.
However the problem I have, is that I prepopulate some options via html. So what happens when I click on the select2 dropdown, it resets the options and waits for keyboard input. When I type in the keyword, it works as it should.
So is there a way to prevent select2, from clearing the items that were pre-populated whenever it gains focus? I would prefer that it would only get reset, once I actually type something in.
var merchantCategorySelect = $('#merchantCategory');
merchantCategorySelect.select2({
width: '100%',
ajax: {
url: "/admin/offers/not-matched/fetch-categories",
data: function (params, page) {
return {
term: params['term'],
merchantId: merchantCategorySelect.data('merchantid'),
}
}
}
});

The UI designer wants the select2 live search to complete when the 'matcher' function reduces the option set to 1 value, w/o having to press the enter key etc.
Is there a select2 setting for this?
You need to catch "results:all" event and trigger "result:select" - it will select currently highlighted item.
var select2 = new Select2({});
select2.on("results:all", function (params) {
if (params.data.results.length === 1) {
select2.trigger('results:select');
}
});
I am using the jQuery UI autocomplete functionality searching and returning some values via ajax. Currently I am using it like this:
$(".myautocomplete").autocomplete(
{
source: "myajaxSourceAsJson",
minLength: 1,
delay: 500,
response: function( event, ui ) {
// Do something with the response data
}
});
My JSON-Object not only contains "value" and "label", but also some more objects, which I am using in the response of the autocomplete. Now I still see the autocomplete-list below the html input field, which I'd simply like to hide, because I don't it in this case. I know I also could create the same same functionality with a "normal" ajax-request and the key-events, but I need the minlength and delay-functionality of the autocomplete. Is there a possibility of hiding the list of results below the input field? I tried with "display:none;" for some of the autocomplete classes, but it quite likely is overwritten by the autocomplete itself.
I also tried
.ui-autocomplete { height: 0px; overflow-y: scroll; overflow-x: hidden;}
But then there is a small area of white pixels visible every time someone triggers a search inside the field.
Now I still see the autocomplete-list below the html input field,
which I'd simply like to hide, because I don't it in this case.
I'm not sure if I fully understand your question... Why would you want auto-complete functionality if you just want to hide it?
But I can recommend using an anonymous function to create the data for your auto-complete..
$(".myautocomplete").autocomplete(
{
source: function(request, response){
// do some data manipulation here...
// perhaps return an empty list...
},
minLength: 1,
delay: 500,
response: function( event, ui ) {
// Do something with the response data
}
});
I have been trying to implement the autocomplete and have come across a problem that has stumped me. The first time I call .autocomplete it all works fine and I have no problems. If, however, I call it after I have removed some (unrelated) elements from the DOM and added a new section to the DOM then autocomplete does nothing and reports no errors.
Code:-
$.ajax({
type : 'get',
dataType : 'json',
url : '/finance/occupations',
cache:true,
success:function(data){
occupationList = data;
$('.js-occupation').autocomplete({
source: occupationList,
messages: {
noResults: '',
results: function(){}
},
minLength : 2,
select:function(event, ui){
$('.js-occupationId').val(ui.item.id);
}
});
}
});
The background to this page is that it contains multiple sections that are manipulated as the user moves through them. Hide and show works fine and does not impact on the autocomplete. However, if I do the following:-
var section = $('.js-addressForm:last').clone();
clearForm(section);
$('div.addressDetails').append(section);
$('.js-addressForm:first').remove();
Which gives the user the bility to add multiple addresses on the previous section then the autocomplete stops working.
Any suggestions or pointers on something obvious I am missing?
I have tried to put the initialisation of the autocomplete on an event when the element gets focus and it still does not work.
You have to create the autocomplete after all other underlying objects. If you F12, you will see that the list is "visible", however it is below and hidden by all instances created after it.
If you created a div with inputs (one input being the autocomplete), then you create the automplete then the dialog instances, the autocomplete will never show. If you create the dialog then the autocomplete, no problem. The problem is the z-order
I have faced the same issue. For now to fix this, i'm creating widget on the input once input is in focus. It will help you solve the issue.
You can look for the help on
making sure some event bing only when needed
Sample code will look like this
$( "#target" ).focus(function() {
//I don't care if you manipulated the DOM or not. I'll be cautious. ;)
(function() {
$( "#combobox" ).combobox();
$( "#toggle" ).click(function() {
$( "#combobox" ).toggle();
});
})();
// use a flag variable if you want
});
This solved my problem. Hope its the solution you were looking f
I'm using the remote validation in MVC 3, but it seems to fire any time that I type something, if it's the second time that field's been active. The problem is that I have an autocomplete box, so they might click on a result to populate the field, which MVC views as "leaving" it.
Even apart from the autcomplete thing, I don't want it to attempt to validate when they're halfway through writing. Is there a way that I can say "only run validation n milliseconds after they are finished typing" or "only run validation on blur?"
MVC 3 relies on the jQuery Validation plugin for client side validation. You need to configure the plugin to not validate on key up.
You can switch it globally off using
$.validator.setDefaults({
onkeyup: false
})
See http://docs.jquery.com/Plugins/Validation/Validator/setDefaults and the onkeyup option here http://docs.jquery.com/Plugins/Validation/validate.
For future reference, I found it's possible to do this in combination with the typeWatch plugin (http://archive.plugins.jquery.com/project/TypeWatch).
Basically what you want to do is (in my case for a slug):
/*Disable keyup validation on focus and restore it to onkeyup validation mode on blur*/
$("form input[data-val-remote-url]").on({
focus: function () {
$(this).closest('form').validate().settings.onkeyup = false;
},
blur: function () {
$(this).closest('form').validate().settings.onkeyup = $.validator.defaults.onkeyup;
}
});
$(function () {
/*Setup the typeWatch for the element/s that's using remote validation*/
$("#Slug").typeWatch({ wait: 300, callback: validateSlug, captureLength: 5 });
});
function validateSlug() {
/*Manually force revalidation of the element (forces the remote validation to happen) */
var slug = $("#Slug");
slug.closest('form').validate().element(slug);
}
If you're using the vanilla typeWatch plugin, you'll have to setup a typeWatch for every element because the typeWatch callback doesn't give you access to the current element via $(this), it only passes the value.
Alternatively you can modify the typeWatch plugin to pass in the element (timer.el) and then you can apply a delay to all.
For some reason (maybe because of conflicts with the unobtrusive plugin), hwiechers' answer didn't work for me. Instead, I had to get the validator of my form with .data('validator') (as mentioned in this answer) and set onkeyup to false on it.
var validator = $('#form').data('validator');
validator.settings.onkeyup = false;
We had the same problem of focusing out the autocomplete textbox "DealingWithContactName" when autocomplete suggestion list pops up. Here we select the dynamically generated autocomplete list item on which the user clicks and set focus on to it. After 50ms we take the focus out from the textbox. It solved our problem.
$('body').on('click', 'ul.ui-autocomplete li a', function () {
$('#DealingWithContactName').focus();
window.setInterval(function () {
$('#DealingWithContactName').blur();
}, 50);
});
I wanted local validation to remain during onkeyup so that the user had a tighter feedback loop. This should only affect the remote validation (that results from RemoteAttribute):
$("[data-val-remote]").keyup(function () {
// Avoid hitting server validation during onkeyup. Wait for onfocusout.
return false;
});
I am trying to get jQuery.post() to run my php script and then open a jQuery UI dialog with the data that php script returns. Its supposed to come back as a form with a table and a textarea in it. It works great with alert(data); and i get a pop-up with all my data.
The problem starts if i turn off alert(). Now it opens 2 dialogs. One containing only the table, without textarea, and the second one absolutely empty.
What am i doing wrong here? How come all my data shows up in the alert(), but not in dialog? What do i need to do to fix it?
Oh, and do i need to also include $.ajax() before the $.post()?
Thank you.
$.post("/path/to/script.php",
{ id: this.id, value: value },
function(data){
// THIS WORKS
//alert(data);
// THIS DOES NOT WORK
$(data).dialog({
autoOpen: true,
width: 400,
modal: true,
position: 'center',
resizable: false,
draggable: true,
title: 'Pending Changes'
});
}
);
You don't need another $.ajax() call. The $.post() method is a wrapper shortcut to $.ajax(). What might be happening is you may be getting both default behavior and Javascript bound behavior. I'm assuming this $.post action triggered on a click. If so, then at the very end of your $.click() handler you need to return false to prevent default behavior.
$('input[type=submit]').click(function() {
$.post( /* ... */ );
return false;
});
This is how I handle it. I have a empty div and initialize the dialog upon document ready. Now on the ajax return load that div's html with the data received from PHP and call the "open" method of dialog. Simple and definitely works.
HTH
Ah! This was not a problem with the JS, but my php file.
The textarea was sitting outside of <div>blah blah</div>.
Problem solved.
