I've got some jQuery code written to enable autocomplete on an input field.
I'm having two issues with it that I can't seem to fix.
Tabbing away from the field will not populate the input. What I need is for either the FIRST suggestion to populate the field if nothing is selected(clicked or selected via up/down) OR for the highlighted item to be populated in the field. (note: highlighting is done via up/down arrows)
When using the up/down arrows I need the input to display the "LABEL" and not the "VALUE" Currently pressing up/down will populate the input the the VALUE.
Any advice will be greatly appreciated.
Here is my JSBIN testing ground.
http://jsbin.com/iyedo3/2
Note: the <input id="dummy" /> field is just there to give you something to "tab" over to. If it's removed the help area is expanded.
I think I've figured this out. Using the jQuery AutoComplete Helper
$(function () {
$(label_element).autocomplete({
source: json_string,
selectFirst: true,
focus: function (event, ui) {
return false;
},
select: function (event, ui) {
$(value_element).val(ui.item.value);
$(label_element).val(ui.item.label);
return false;
}
});
});
And the following Select First Script
(function ($) {
$(".ui-autocomplete-input").live("autocompleteopen", function () {
var autocomplete = $(this).data("autocomplete"),
menu = autocomplete.menu;
if (!autocomplete.options.selectFirst) {
return;
}
menu.activate($.Event({ type: "mouseenter" }), menu.element.children().first());
});
} (jQuery));
Now anywhere I need to add autocomplete, I just use this.
<script type="text/javascript">
var json_string = // My Autocomplete JSON string.
var label_element = "#RegionName";
var value_element = "#RegionID";
</script>

I'm playing around with jQueryUI Accordion for the first time and I'm trying to make simple expanding div, which switches it's header text and sliding to the bottom of the content, when expanded.
I have the default h3 header saying 'More' and I want it to change to 'Less', when the div is expanded and revert to 'More', when it is closed. Also, the header should slide down and stay below the content, when expanded.
I've been searching for 2 days with no luck.
Change text by #Irvin Dominin aka Edward
$(function() {
$( "#accordion" ).accordion({
header: 'h3',
collapsible: true,
active: false,
activate: function (event, ui) {
ui.newHeader.find(".accordion-header").text("Less")
ui.oldHeader.find(".accordion-header").text("More")
}
});
Slide Header by #vitaliy zadorozhnyy
var headers = $('#accordion h3');
headers.click(function () {
var panel = $(this).prev();
var isOpen = panel.is(':visible');
$(this).text(!isOpen ? 'Less' : 'More');
panel[isOpen ? 'slideUp' : 'slideDown']();
return false;
});
Now the problem is these two can't be used together. Any idea how to mix them?
You can use activate event to switch your accordion header text:
Triggered after a panel has been activated (after animation
completes). If the accordion was previously collapsed, ui.oldHeader
and ui.oldPanel will be empty jQuery objects. If the accordion is
collapsing, ui.newHeader and ui.newPanel will be empty jQuery objects.
Code:
$('#accordion').accordion({
activate: function (event, ui) {
ui.newHeader.find(".accordion-header").text("Less")
ui.oldHeader.find(".accordion-header").text("More")
}
});
Demo: http://jsfiddle.net/IrvinDominin/r93wn/
if you use accordion with one item and want to slide it when it is active then use collapsible option
In your case $('#accordion').accordion({collapsible:true});
but if u want to slide header down you can use another approach. I have made some sample on JsFiddle for you.
Hope it helps.
Currently I am using a Jquery ui autocomplete, and after someone selects an option from a Jquery ui autocomplete, I am removing the focus from the textbox.
I would like to add the following functionality -
When someone clicks into the textbox again, I would like to leave the option that was previously selected in the text box, but highlight it (as if the text was double clicked), and redisplay all the choices.
How can this be done?
CURRENT CODE -
$(function () {
var availableItems = ['item1', 'item2', 'item3'];
$("#myTextBox").autocomplete({
source: availableItems,
minLength: 0,
select: function(event, ui) {
$('#myTextBox').blur();
}
}).focus(function () {
$(this).autocomplete("search");
}); ;
});
Did you try to put
$(this).select();
in the focus function()?
Also try
$(this).autocomplete("search", "");
to enhance an empty search
I know I'm missing something very basic, but when using jQuery in a situation where you have stacked "droppable" DIVs on top of each other (think nested boxes), how do you allow and accept an element drop on the top most DIV and then cancel the drag/drop event so it is not also sent to the other "droppable" DIVs below?
$('#'+objectID+" .task-droppable").droppable({
accept: function(d) {
if(d.hasClass("source-task")||d.hasClass("source-sequence")){ //sequences can contain both sequences and tasks
return true;
} //end if
}, //end accept
activeClass: "isDropDest",
//hoverClass: "isDragging",
//this is used for both drag/drop and item moves
drop: function(event, ui) {
var draggableId = ui.draggable.attr("id");
var droppableId = $(this).attr("id");
//var sender_id = ui.sender.attr('id');
//var receiver_id = $(this).attr('id');
//var item_id = ui.item.attr('id');
//var above_id = ui.item.prev().attr('id');
//var below_id = ui.item.next().attr('id');
//check if this is a drag/drop or a move by looking for the object class
if(!$('#'+draggableId).hasClass('object')) {
$('#'+draggableId).css('top', '0px');
$('#'+draggableId).css('left', '0px');
createObject(draggableId, droppableId);
} else {
//handle the move - do nothing
} //end if
event.stopPropagation();
} //end drop
}); //end droppable
Sorry, not enough coffee today.
Sounds like you may need to use the greedy option
By default, when an element is dropped on nested droppables, each
droppable will receive the element. However, by setting this option to
true, any parent droppables will not receive the element.
$( ".selector" ).droppable({ greedy: true });
Working Example
is it possible to disable single headers in jquery ui 1.9? I had a quation runing about this, while i was using 1.8 and there it wasnt possible. I fond a way, but its really hard coded. It opens the tab and if the user doesnt have permitions to it , the tab closes. So is there any better way now?
best regrads.
I found a way and i thought ill share it hopefully it will help some one else a lot. :)
$(function() {
var icons = {
header: "h3",
activeHeader: "ui-icon-circle-arrow-s"
};
$( "#prod_accordion" ).accordion({
active:<?php echo $db_obj->getValue('status') ? 'acc_'.$tab_status : 'acc_0'; ?>,
icons: icons,
autoHeight: false,
beforeActivate: function(event, ui) {
var newIndex = $(ui.newHeader).index('h3');
if (jQuery.inArray(newIndex , accordion_array) == -1) {
event.preventDefault();
}
}
});
});
the accrodion_array is an array with indexes like (1,2,3,4) and i check if the index of the clicked accordion lets say 5 is in the array. If not then perventDefault() and the accordion header wont open.
if u add ui.addClass('ui-state-disabled'); to the accordion headers that are not in the array the user will now what accordion he cant open. :)
I'm using jqueryui combobox example at http://jqueryui.com/demos/autocomplete/combobox.html
I added the script seen below to catch the selected value of combobox:
<div id="selectedOpt">
</div>
<script>
$(document).ready(function() {
$("#combobox").change(function() {
var retval = $(this).val();
$("#selectedOpt").html("retval=" + retval);
});
});
</script>
However, it does not work as expected:
the div selectedOpt does not show selected value of combobox each time
the change event occurs
If "show underlying effect" is selected (pls try at url above), a standard dropdown list
appear. When trying to change value of
that dropdown list, then the div
selectedOpt is able to show value
correctly.
The goal is to have div selectedOpt display the selected option of the combobox.
Please advise and please explain why (1) does not work while (2) works.
PS: all neccessary js, css are correctly included.
Thanks for your kind attention.
SOLUTION FOUND:
http://robertmarkbramprogrammer.blogspot.com/2010/09/event-handling-with-jquery-autocomplete.html
Please change your script to match the code below:
<script>
function test()
{
var retval = $("[id *=dropdown] :selected").val();
$("#selectedOpt").html("retval=" + retval);
}
</script>
And call this script from the server side like this:
dropdown.Attributes.Add("onchange","javascript: return test();")
To show label or value of combobox in your div you have to include your function as an option. Something like this:
$( ".selector" ).autocomplete({
change: function(event, ui) {
$("#selectedOpt").html("retval=" + ui.item.value);
}
});
Use ui.item.label if you want a label instead.
