Jquery autocompelete - key press - jquery-ui

We want to implement autocompelete using Jquery.
We need to enable the user to add text and to save the new text.
something like on key press event.
In Addition I want enable to user to add text into the input text.
$('#id').autocomplete({
source: url,
select: function (event, ui) {
// code..
}
});
We have tried to do this using change event , but this is not good enough since according to the API the change event is fire only after onBlur is fire (when the user live the input text).
Can someone help how to solve this problem?
Thanks,
John & Yuri.

$('#id').autocomplete({
source:function(request, response)
{
var text = $("#idofthetext").val()
alert(text);
}
select: function (event, ui) {
// code..
}
});
do you want to do something like this? var text will give you the text when user type in the input field with id "idofthetext".

Get the referred link id on pagebeforeshow

In jqm I have something like this
<li>cats</li>
<li>dogs</li>
Page1 is a dynamic page and should load it's contents based on which link button I pressed and I use
$(document).on('pagebeforeshow', '#page1', function(event, data){
do something here with either cats or dogs
});
Now how do I determine here what link what used?
I could use sessionStorage or perhaps a
$('.loadPage').click(function(){
$(this).attr('id').blablabla
})
but it doesn't seem right to me. I'm sure the answer is there right in front of me, but I can't seem to get around it.
Any ideas?
You could store the id in #page1's data attribute on click of loadPage:
$(document).on("pageinit", "#page0", function () {
$(this).on("click", ".loadPage", function (e) {
e.preventDefault();
$("#page1").data("id", this.id);
});
});
Then, after jQM redirects you to #page1, check for the stored data :
$(document).on("pagebeforeshow", "#page1", function () {
alert($(this).data("id"));
// you can do anything with this id
});
Demo : http://jsfiddle.net/hungerpain/wN2L9/
compare the id:
if(this.id==='cats')
{
//do something here
}
On a side note you can use $(this).attr('id') also, but its better you use pure JavaScript whenever possible.

jquery mobile trigger click doesn't work the first time

I have a jquery mobile form with several radio inputs whit the options "DS", "NO" and "YES". I want when I click a button it simulates a click on the "YES" option of all radio buttons.
I use this code:
$("#btn-all-yes").click(function(){
$(".replay-yes").each(function(index, element){
$(element).trigger("click");
//$(element).click();
});
});
But I need to do click two times in the button to achieve the desired result. If I put the line '$(element).trigger("click")' two times it works, but I think it should work with a single call to the click event.
You can see all the code at http://jsfiddle.net/qwLPH/7/
You need to change its' status using .prop and then refresh it .checkboxradio('refresh').
Working demo
Update - Uncheck other buttons
$("#btn-all-yes").click(function () {
$('[data-role="controlgroup"]').find("[type=radio]").each(function () {
if ($(this).hasClass('replay-yes')) {
$(this).prop('checked', true).checkboxradio("refresh");
} else {
$(this).prop('checked', false).checkboxradio("refresh");
}
});
});
Old answer
$("#btn-all-yes").click(function(){
$(".replay-yes").each(function(index, element){
$(element).prop('checked', true).checkboxradio("refresh");
});
});

Try to initialize the click on page load:
$(".replay-yes").each(function (index, element) {
$(element).trigger("click");
//$(element).click();
}).click();

Disable Enable unobtrusive validation for specific submit button

I have two submit buttons Back, Continue. What should I to do to disable client validation when I click on Back. I was trying to add cancel class to button attribute but It seams does not help.
UPD. Actually this is working cancel class. But It seams not working if you add it dynamically(by javascript).
I attached an event handler to certain buttons, that altered the settings of the validator object on that particular form.
$(".jsCancel").click(function (e) {
$(e.currentTarget).closest("form").validate().settings.ignore = "*"
});
This has worked like a charm for me in MVC3.
I don't know if this helps you in particular, but since I use ajax form, I had to attach the event to these buttons each time the contents of the ajax form was replaced, by using the event ajax success. The full code that reparses the form and attaches the event to the cancel buttons is:
$(document).ajaxSuccess(function (event, xhr, settings) {
var $jQval = $.validator, adapters, data_validation = "unobtrusiveValidation";
$jQval.unobtrusive.parse(document);
$(".jsCancel").click(function (e) {
$(e.currentTarget).closest("form").validate().settings.ignore = "*"
});
});
Hijack the button click for form submission using JavaScript.
Here is good example with jQuery:
$("#MyButton").click(function(e) {
//submit your form manually here
e.preventDefault();
});
This is really a comment to the answer by tugberk, but comments don't show code examples very well.
Some browser versions do not like the "preventDefault()" function. After being bitten by this a few times, I added a simple utility function:
//Function to prevent Default Events
function preventDefaultEvents(e)
{
if (e.preventDefault) {
e.preventDefault();
} else {
e.returnValue = false;
}
}
You call it in place of "preventDefault" like this:
$("#CancelButton").on("click", function(event) {
preventDefaultEvents(event);
return false;
});
You can use "cancel" css class.
Ex: <input type="submit" value="Cancel" name="Cancel" class="cancel" />
JQuery.Validate handle the rest in the following code:
// allow suppresing validation by adding a cancel class to the submit button
this.find("input, button").filter(".cancel").click(function() {
validator.cancelSubmit = true;
});

jQuery UI autocomplete select event not working with mouse click

I have a list of links, and I have this search box #reportname. When the user types in the search box, autocomplete will show the text of the links in a list.
<div class="inline">
<div class="span-10">
<label for="reportname">Report Name</label>
<input type="text" name="reportname" id="reportname" />
</div>
<div class="span-10 last">
<button type="button" id="reportfind">Select</button>
</div>
</div>
The user can then use the keyboard arrow to select one of the text, and when he press ENTER, browser will go to the address of the link. So far so good.
<script type="text/javascript">
$(document).ready(function () {
$("#reportname").autocomplete({
source: $.map($("a.large"), function (a) { return a.text }),
select: function () { $("#reportfind").click() }
})
$("#reportfind").click(function () {
var reportname = $("#reportname")[0].value
var thelinks = $('a.large:contains("' + reportname + '")').filter(
function (i) { return (this.text === reportname) })
window.location = thelinks[0].href
})
});
</script>
The issue is when the user types, autocomplete shows a list, and then the user use the mouse to click one of the result. With keyboard navigation, the content of the search box is changed, but if the user clicks one of the options, the search box is not modified and the select event is immediately triggered.
How can I make the script work with keyboard selection and mouse selection? How can I differentiate between select events that are triggered by keyboard with the ones triggered by mouse?
To your 2nd question: "How can I differentiate between select events that are triggered by keyboard with the ones triggered by mouse?"
The event object in the jQuery UI events would include a .originalEvent, the original event it wrapped. It could have been wrapped multiple times though, such as in the case of Autocomplete widget. So, you need to trace up the tree to get the original event object, then you can check for the event type:
$("#reportname").autocomplete({
select: function(event, ui) {
var origEvent = event;
while (origEvent.originalEvent !== undefined)
origEvent = origEvent.originalEvent;
if (origEvent.type == 'keydown')
$("#reportfind").click();
},
...
});
Thanks to #William Niu and firebug, I found that the select event parameter 'ui' contains the complete selected value: ui.item.value. So instead of depending on jquery UI to change the text of the textbox, which didn't happen if the user clicks with mouse, I just pick up the selected value from 'ui':
$("#reportname").autocomplete({
select: function (event, ui) {
var reportname = ui.item.value
var thelinks = $('a.large:contains("' + reportname + '")').filter(
function (i) { return (this.text === reportname) })
window.location = thelinks[0].href
};
})
I tested it in all version of IE (inlcuding 9) and always ended up with an empty input-control after I selected the item using the mouse. This caused some headaches. I even went down to the source code of jQuery UI to see what happens there but didn’t find any hints either.
We can do this by setting a timeout, which internally queues an event in the javascript-engine of IE. Because it is guaranteed, that this timeout-event will be queued after the focus event (this has already been triggered before by IE itself).
select: function (event, ui) {
var label = ui.item.label;
var value = ui.item.value;
$this = $(this);
setTimeout(function () {
$('#txtBoxRole').val(value);
}, 1);
},
Had the same issue / problem.
Jquery: 1.11.1
UI: 1.11.0
Question: Do you use bassistance jquery validte plugin simultanously?
If positive: update this to a newest version or just disable it for tests.
I updated from 1.5.5 to 1.13.0
Helped for me. Good luck!
I recently encountered the exact same problem (autocomplete items not clickable, keyboard events working).
Turned out that in my case the answer was not at all JS related. The autocomplete UI was not clickable simply because it was lacking an appropriate value for the z-index CSS property.
.ui-autocomplete {
z-index: 99999; /* adjust this value */
}
That did the trick.
This may be a bit farshot, but I had a similar situation where selecting an autocomplete value left the input field empty. The answer was to ignore the "change" events (as those were handled by default) and replace them with binds to "autocompletechange" events.
The "change" event gets triggered before the value from autocomplete is in the field => the field had "empty" value when handling the normal "change" event.
// ignore the "change" event for the field
var item = $("#"+id); // JQuery for getting the element
item.bind("autocompletechange", function(event, ui) { [call your handler function here] }
I was facing a similar problem. I wanted to submit the form when the user clicked on an option. But the form got submitted even before the value of the input could be set. Hence on the server side the controller got a null value.
I solved it using a modified version of William Niu's answer.

I had the same issue, mouse click was not selecting the item which was clicked.My code was supposed to make an ajax call to fetch the data as per the selection item from autocomplete source.
Previous code: mouse click not working.
select: function(event, ui) {
event.preventDefault();
for(i= 0; i< customer.length; i++)
if(document.getElementById('inputBox').value == customer[i].name)
{
$.ajax({
call
})
Changed code :mouse click working
select: function(event, ui) {
// event.preventDefault();
for(i= 0; i< customer.length; i++)
// if(document.getElementById('inputBox').value == customer[i].fields.name)
if(ui.item.value == customer[i].name)
{
$.ajax({
call
})
After inspecting the code in the developer tools console, I noticed there were two list items added. I removed the pairing <li></li> from my response code and oh yeah, the links worked
I also added this function as the click event:
$("#main-search").result(function ()
{
$("#main-search").val("redirecting...."), window.location.href = $("#main-search").attr("href").match(/page=([0-9]+)/)[1];
})
This works and you can test it here: Search for the term dress -->

jqueryUI Sortable: handling .disableSelection() on form inputs

example: i have an un-ordered list containing a bunch of form inputs.
after making the ul .sortable(), I call .disableSelection() on the sortable (ul) to prevent text-selection when dragging an li item.
..all fine but I need to re/enable text-selection on the form inputs.. or the form is basically un-editable ..
i found a partial solution # http://forum.jquery.com/topic/jquery-ui-sortable-disableselection-firefox-issue-with-inputs
enableSelection, disableSelection seem still to be un-documented: http://wiki.jqueryui.com/Core
any thoughts?
solved . bit of hack but works! .. any comments how i can do this better?
apply .sortable() and then enable text-selection on input fields :
$("#list").sortable({
stop: function () {
// enable text select on inputs
$("#list").find("input")
.bind('mousedown.ui-disableSelection selectstart.ui-disableSelection', function(e) {
e.stopImmediatePropagation();
});
}
}).disableSelection();
// enable text select on inputs
$("#list").find("input")
.bind('mousedown.ui-disableSelection selectstart.ui-disableSelection', function(e) {
e.stopImmediatePropagation();
});
A little improvement from post of Zack - jQuery Plugin
$.fn.extend({
preventDisableSelection: function(){
return this.each(function(i) {
$(this).bind('mousedown.ui-disableSelection selectstart.ui-disableSelection', function(e) {
e.stopImmediatePropagation();
});
});
}
});
And full solution is:
$("#list").sortable({
stop: function () {
// enable text select on inputs
$("#list").find("input").preventDisableSelection();
}
}).disableSelection();
// enable text select on inputs
$("#list").find("input").preventDisableSelection();
jQuery UI 1.9
$("#list").sortable();
$("#list selector").bind('click.sortable mousedown.sortable',function(e){
e.stopImmediatePropagation();
});
selector = input, table, li....
I had the same problem. Solution is quite simple:
$("#list").sortable().disableSelection();
$("#list").find("input").enableSelect();
The following will disable selection for the entire document, but input and select elements will still be functional...
function disableSelection(o) {
var $o = $(o);
if ($o.find('input,select').length) {
$o.children(':not(input,select)').each(function(x,e) {disableSelection(e);});
} else {
$o.disableSelection();
}
}
disableSelection(document);
But note that .disableSelection has been deprecated by jquery-ui and will someday go away.
EASY! just do:
$( "#sortable_container_id input").click(function() { $(this).focus(); });
and replace "sortable_container_id" with the id of the element that is the container of all "sortable" elements.
Quite old, but here is another way:
$('#my-sortable-component').sortable({
// ...
// Add all non draggable parts by class name or id, like search input texts and google maps for example
cancel: '#my-input-text, div.map',
//...
}).disableSelection();
