How can I add an option to a menu at the begining of the select menu?
I know the append will add the end
SomeSelectMenu.append(NewElement);
But how will I add at the beginning?
Here is an example:
<select>
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="mercedes">Mercedes</option>
<option value="audi">Audi</option>
</select>
Please specify an answer with Jquery and one without (if possible)
Thanks
You are so close! :)
.prepend( content, [content] )
$('select').prepend('<option value="i-came-first">Hey!</option>');

I am looking for a way to select an option from a drop down list using the item class, and containing text. For example
<select class="mySelect">
<option value="Test 1">Test 1</option>
<option value="Test 2">Test 2</option>
<option value="Test 3">Test 3</option>
</select>
I cannot use the select ID because it might change, but the class will always be the same. I want to do, if option has the word Test, make the color of the word "Test" blue.
I think I can handle the color assignment, but what I am having an issue with is using the class to select the child options. I have tried:
$('.mySelect option:contains("Test")');
However I get an error that this is not a valid selector.
I also tried:
$('.mySelect select option:contains("Test")');
Finally, thanks to comments, I tried
$('select option[value*="Test"]')
However, this only returns the first item.
OK, here is the actual code in production, lets see if this changes anything.
<select onclick="SetChoiceOption('ctl00_ctl40_g_6a07f243_6d33_4cb8_bf98_47743415ee4a_ctl00_ctl05_ctl05_ctl00_ctl00_ctl05_ctl00_DropDownButton')" name="ctl00$ctl40$g_6a07f243_6d33_4cb8_bf98_47743415ee4a$ctl00$ctl05$ctl05$ctl00$ctl00$ctl05$ctl00$DropDownChoice" id="ctl00_ctl40_g_6a07f243_6d33_4cb8_bf98_47743415ee4a_ctl00_ctl05_ctl05_ctl00_ctl00_ctl05_ctl00_DropDownChoice" title="Category: Choice Drop Down" class="ms-RadioText">
<option selected="selected" value=""></option>
<option value="Meeting Test">Meeting Test</option>
<option value="Work hours Test">Work hours Test</option>
<option value="Business Test">Business Test</option>
<option value="Holiday Test">Holiday Test</option>
<option value="Get-together Test">Get-together Test</option>
<option value="Gifts Test">Gifts Test</option>
<option value="Birthday Test">Birthday Test</option>
<option value="Anniversary Test">Anniversary Test</option>
</select>
Here is a fiddle that returns each as text, but, somehow does not return the elements.

$('.mySelect option:contains("Test")'); is valid and is selecting the three options. but as an alternative you can try this:
$('select option[value^="Test"]')
$$('select option[value*="Test"]');
was the answer. I got the additional piece from Simple jQuery selector only selects first element in Chrome..?
I am working with select box. I use select box like as below:
<select name="cars" onchange="jsFunction()">
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="fiat">Fiat</option>
<option value="audi">Audi</option>
</select>
<script>
function jsFunction(){
console.log($(.names).val());
}
<script>
The combo is look like as below:
THis function is working when the comboboz is chenged.But i want to show all option at the same time. But i don't want to use multiple option select. So that i used size option like as below:
<select name="cars" size="4" onchange="jsFunction()">
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="fiat">Fiat</option>
<option value="audi">Audi</option>
</select>
And then the select box look like as below:
And only only one option can selected. But my problem is not working function. When i use size attribute, and then the function is not triggered when selectbox is changed. When i remove this size, and then the function is triggered.
How can i show all option at the same time (without multiselect) without using size attribute ? Or how can i trigger this function with size attribute ?
Your JavaScript function shouldn't log anything at all, as it has a syntax error. $(.names) needs quotes around names. Also, it needs to reflect the class of your <select>.
First you need to add the class names to your select:
<select name="cars" size="4" class="names" onchange="jsFunction()">
And then add quotes around your jQuery DOM target:
console.log($('.names').val());
Here's the new code:
function jsFunction() {
console.log($('.names').val());
}
<select name="cars" size="4" class="names" onchange="jsFunction()">
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="fiat">Fiat</option>
<option value="audi">Audi</option>
</select>
I've created a fiddle showcasing this here.
Hope this helps!

I have below html code.

The problem is when it goes beyond the page then it gives vertical scroll bar. But the problem is if the value is too large then select box width is auto expanded to accommodate the width of the value. But i don't want it to expand. I want a horizontal scrollbar to come if the option value is too large.
How can I do that?
As others have said, this is not possible. However, there is no need for a scrollbar on the option list if your goal is simply to make the select small while keeping the options fully visible. If you limit the width of your select through CSS, you will see that the browser automatically makes the whole width of the option list visible.
select { width: 100px; }
Edit: See my previous answer on this topic. Firefox, Chrome, and IE10 will make the option list wider than the select if necessary, but IE9 will not. The other answers to that question link to this question with fixes for old IE: Dropdownlist width in IE.
You can't. The native controls are completely governed by the browsers HTML renderer. You'll need to look at a <select> styling plugin if you want to style the dropdown.
Unfortunately you cant do horizontal scrollbars using the default select boxes. You could try using a javascript replacement like Select2 or Chosen. Both of these allow you to format the dropdown options with CSS and you should be able to control their formatting however you like.
I would like to dynamically change the option value of a select tag. Is this possible? When I say value, I mean the "Change Me" portion. If this is possible, can someone please show me how?
<option value="0">Change Me</option>
You can fetch and modify the combobox item's text as follows:
$("#MyCombo option:selected").text()
Note: #shaz; thanks for your comment, my mistake!
Yes it is possible
You will need to look at the options available using a select tag.
<select id='selection'>
<option value='0'>Value 0</option>
<option value='1'>Value 1</option>
<option value='2'>Value 2</option>
<option value='3'>Value 3</option>
<option value='4'>Value 4</option>
<option value='5'>Value 5</option>
</select>
the javascript
var select = document.getElementById('selection');
// to get the currently selected item, use the `selectedIndex` property.
var index = select.selectedIndex; // 3 in case of value 2 selected
// to change its text
select.options[index].innerHTML = 'the new value';
is this what u are looking for?
