jQuery UI MultiSelect are selecting all <select> in the page

jQuery UI MultiSelect are selecting all <select> in the page - javascript

I'm using the plugin jQuery UI MultiSelect http://www.erichynds.com/examples/jquery-ui-multiselect-widget/demos/.
But I want just one <select> determinated by me to be multiple!
I alrealy have others <select> on my page (simple selects), like this:
<select name='simple_select' id='simples_select'>
<option value='1'>Option 1</option>
</select>
And, for the multiple <select>:
<select multiple="multiple" name='multiple_select' id='multiple_select'>
<option value='1'>Option 1</option>
</select>
When I change this function from "select" to something else, (like "div") all the divs stay "multiple". So, like this function (downloaded from the plugin site), all the <select> will be multiple... and I just one specific.
<script type="text/javascript">
$(function(){
$("select").multiselect();
});
</script>
Anyone have any idea how can I make it? Thanks for reading and I'm sorry about the terrifying english (I'm brazilian). ^^

Try using :not() to exclude a select you don't want calling it's ID inside :not()
$(function(){
$("select:not(#simples_select)").multiselect();
});
Demo
Or just use the ID selector for the one that you want, since it has ID:
$(function(){
$("#multiple_select").multiselect();
});
Demo

Unless you specifically want to apply something across a group of tags or objects it's much better practice to use IDs. To apply the code to the specific ID use the # symbol with the ID.
You can learn about CSS selectors with jQuery here: http://api.jquery.com/category/selectors/
<script type="text/javascript">
$(function(){
$("#multiple_select").multiselect();
});
</script>

If you want to select all <select> use $('select') and if you only want to select a specific <select> use $('#mySelect').

Open selectbox option using jquery

I want to show selectbox option using jquery when the page loads. I have used .simulate() and .trigger function but it's not working, so can you please suggest some solution for that.
Code:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.0/jquery.min.js"></script>
<script src="simulate.js"></script>
<script>
$(document).ready(function(){
$("#test").simulate('mousedown'); // not working
$("#test").trigger('click'); // not working
//$("#test").attr('size',3); // size is not as i need. i want to display option as any dropdown shows.
});
</script>
<select id="test">
<option value="0">select option</option>
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
</select>
Please help me to out from this problem...

Try this...
$(document).ready(function(){
var myDropDown=$("#test");
var length = $('#test> option').length;
myDropDown.attr('size',length);
$("#test").click(function(){
myDropDown.attr('size',0);
});
});

I think it's not possible. There's a lot of jQuery plugins out there to enhance the native select's functionality, like the Selectmenu Widget of jQuery UI which has an "open" method:
http://api.jqueryui.com/selectmenu/#method-open
or for Twitter Bootstrap:
http://silviomoreto.github.io/bootstrap-select/methods/#selectpickershow
just to name some...

It's not possible to open a selectbox with JavaScript.
I tried and got disappointed. I finally changed the attribute size for the select box so it appears to be open:
$('#test').attr('size',3);
and then when you're finished
$('#test').attr('size',0);
Hope that helps :)

JQuery set select using .prop('selectedIndex', #) not working

I'm using the following line to set a option from a select menu:
$('select').prop('selectedIndex', 2)
Using the following site as a example:
http://shoebaloo.nl/michael-by-michael-kors-chelsea-skate-leo-bruin-dessin-285000097-women-sneakers.html
I am indeed seeing the select option going to the second option but it wont have the same effect as actually clicking on the second option.
Can someone help me so the page actually recognises me "clicking" on a option?

You need to select the option with a selector.
$('select option:eq(2)').prop('selected', true)
If you're looking to manually trigger a click or change event, you could use the .trigger('click') or .trigger('change') methods.
http://jsfiddle.net/j5v6tp7t/4/

All you should have to do is use .val() to set the value.
For example:
$('select').val('2')
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<select>
<option value="1">a</option>
<option value="2">b</option>
<option value="3">c</option>
<option value="4">d</option>
</select>

Your expression was right but the correct syntax is :
$('select').get(0).selectedIndex = 2;

Remove items multi select with optgroup in jquery

Is there a way to clear all option and optgroup HTML elements by using jquery?
My HTML select element is like this,
<select id="users" name="multiselect" multiple="multiple" style="width:382px;" >
<optgroup id="groupadmin" label="Group Admin"></optgroup>
<optgroup id="systemusers" label="System User"></optgroup>
</select>

You can use .empty()
Description: Remove all child nodes of the set of matched elements from the DOM.
Code
$('#users').empty()
Fiddle
EDIT
As you are using multiSelect plugin, You need to use .multiSelect('refresh') method.
$('#users').empty().multiSelect('refresh');
Updated Fiddle

Try this code
$('#users').find('optgroup,option').remove();

Use the following code :
$('#users').children().remove();
This will work irrespective of whether an optgroup is present or not

jQuery Multiple Select

I have a multiple select HTML element.
<select multiple="multiple" id="mult_sel">
<option value="1">Dog</option>
<option value="2">Cat</option>
</select>
I'm using the following jQuery to capture when a single option in this multiple select is clicked on with the following:
$('#mult_sel').click(function(v){
console.log(v);
});
This event triggers as expected, however, I'm not sure how to get the value and text values of the single option that was clicked for a multiple select field.
Thanks!

try
$('#mult_sel option').click(function(){
alert('the value ' $(this).val()); //for get the value
alert('the text' $(this).text()); //for get the text
});
The .val() return the value of the option, and the .text() return the text of the option selected.
Jsfiddle

jsfiddle
$('#mult_sel').click(function(event){
// event.originalEvent.srcElement isn't fully supported
console.log(e.target);
});
there ya go :-) (do check if it's an [option] or a [select] element)

Try to use Select2 JQuery
you must download the code from GitHub and copy the dist directory to your project.
Include the following lines of code in the <head> section of your HTML.
<link href="../css/select2.min.css" rel="stylesheet" />
<script src="../js/select2.min.js"></script>
Initialize Select2 on the <select> element that you want to make it multiple select boxes.
<script type="text/javascript">
$('#select2-multiple').select2();
</script>
Example Code (Remember to declared with the multiple attribute)
<select class="select2-multiple" multiple="multiple">
<option value="WWL">Wong Wai Ling</option>
<option value="AE">Alessia Enzler</option>
<option value="ASL">A-Young SON LAuren</option>
</select>

jQuery get specific option tag text

All right, say I have this:
<select id='list'>
<option value='1'>Option A</option>
<option value='2'>Option B</option>
<option value='3'>Option C</option>
</select>
What would the selector look like if I wanted to get "Option B" when I have the value '2'?
Please note that this is not asking how to get the selected text value, but just any one of them, whether selected or not, depending on the value attribute. I tried:
$("#list[value='2']").text();
But it is not working.

If you'd like to get the option with a value of 2, use
$("#list option[value='2']").text();
If you'd like to get whichever option is currently selected, use
$("#list option:selected").text();

It's looking for an element with id list which has a property value equal to 2.
What you want is the option child of the list:
$("#list option[value='2']").text()

This worked perfectly for me, I was looking for a way to send two different values with options generated by MySQL, and the following is generic and dynamic:
$(this).find("option:selected").text();
As mentioned in one of the comments. With this I was able to create a dynamic function that works with all my selection boxes that I want to get both values, the option value and the text.
Few days ago I noticed that when updating the jQuery from 1.6 to 1.9 of the site I used this code, this stop working... probably was a conflict with another piece of code... anyway, the solution was to remove option from the find() call:
$(this).find(":selected").text();
That was my solution... use it only if you have any problem after updating your jQuery.

Based on the original HTML posted by Paolo I came up with the following.
$("#list").change(function() {
alert($(this).find("option:selected").text()+' clicked!');
});
It has been tested to work on Internet Explorer and Firefox.

$("#list option:selected").each(function() {
alert($(this).text());
});
for multiple selected value in the #list element.

If there is only one select tag in on the page then you can specify select inside of id 'list'
jQuery("select option[value=2]").text();
To get selected text
jQuery("select option:selected").text();

Try the following:
$("#list option[value=2]").text();
The reason why your original snippet wasn't working is because your OPTION tags are children to your SELECT tag, which has the id list.

This is an old Question which has not been updated in some time the correct way to do this now would be to use
$("#action").on('change',function() {
alert($(this).find("option:selected").text()+' clicked!');
});
I hope this helps :-)

I wanted to get the selected label. This worked for me in jQuery 1.5.1.
$("#list :selected").text();

$(this).children(":selected").text()

You can get selected option text by using function .text();
you can call the function like this :
jQuery("select option:selected").text();

$("#list [value='2']").text();
leave a space after the id selector.

While "looping" through dynamically created select elements with a .each(function()...): $("option:selected").text(); and $(this + " option:selected").text() did not return the selected option text - instead it was null.
But Peter Mortensen's solution worked:
$(this).find("option:selected").text();
I do not know why the usual way does not succeed in a .each() (probably my own mistake), but thank you, Peter. I know that wasn't the original question, but am mentioning it "for newbies coming through Google."
I would have started with $('#list option:selected").each() except I needed to grab stuff from the select element as well.

Use:
function selected_state(){
jQuery("#list option").each(function(){
if(jQuery(this).val() == "2"){
jQuery(this).attr("selected","selected");
return false;
}else
jQuery(this).removeAttr("selected","selected"); // For toggle effect
});
}
jQuery(document).ready(function(){
selected_state();
});

I was looking for getting val by internal field name instead of ID and came from google to this post which help but did not find the solution I need, but I got the solution and here it is:
So this might help somebody looking for selected value with field internal name instead of using long id for SharePoint lists:
var e = $('select[title="IntenalFieldName"] option:selected').text();

A tip: you can use below code if your value is dynamic:
$("#list option[value='"+aDynamicValue+"']").text();
Or (better style)
$("#list option").filter(function() {
return this.value === aDynamicValue;
}).text();
As mentioned in jQuery get specific option tag text and placing dynamic variable to the value

I needed this answer as I was dealing with a dynamically cast object, and the other methods here did not seem to work:
element.options[element.selectedIndex].text
This of course uses the DOM object instead of parsing its HTML with nodeValue, childNodes, etc.

As an alternative solution, you can also use a context part of jQuery selector to find <option> element(s) with value="2" inside the dropdown list:
$("option[value='2']", "#list").text();

I wanted a dynamic version for select multiple that would display what is selected to the right (wish I'd read on and seen $(this).find... earlier):
<script type="text/javascript">
$(document).ready(function(){
$("select[showChoices]").each(function(){
$(this).after("<span id='spn"+$(this).attr('id')+"' style='border:1px solid black;width:100px;float:left;white-space:nowrap;'> </span>");
doShowSelected($(this).attr('id'));//shows initial selections
}).change(function(){
doShowSelected($(this).attr('id'));//as user makes new selections
});
});
function doShowSelected(inId){
var aryVals=$("#"+inId).val();
var selText="";
for(var i=0; i<aryVals.length; i++){
var o="#"+inId+" option[value='"+aryVals[i]+"']";
selText+=$(o).text()+"<br>";
}
$("#spn"+inId).html(selText);
}
</script>
<select style="float:left;" multiple="true" id="mySelect" name="mySelect" showChoices="true">
<option selected="selected" value=1>opt 1</option>
<option selected="selected" value=2>opt 2</option>
<option value=3>opt 3</option>
<option value=4>opt 4</option>
</select>

You can get one of following ways
$("#list").find('option').filter('[value=2]').text()
$("#list").find('option[value=2]').text()
$("#list").children('option[value=2]').text()
$("#list option[value='2']").text()
$(function(){
console.log($("#list").find('option').filter('[value=2]').text());
console.log($("#list").find('option[value=2]').text());
console.log($("#list").children('option[value=2]').text());
console.log($("#list option[value='2']").text());
});
<script src="//ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
<select id='list'>
<option value='1'>Option A</option>
<option value='2'>Option B</option>
<option value='3'>Option C</option>
</select>

Try this:
jQuery("#list option[value='2']").text()

Try
[...list.options].find(o=> o.value=='2').text
let text = [...list.options].find(o=> o.value=='2').text;
console.log(text);
<select id='list'>
<option value='1'>Option A</option>
<option value='2'>Option B</option>
<option value='3'>Option C</option>
</select>
