<select id="my-select">
<option value="1">This is one</option>
<option value="2" selected>This is two</option>
...
</select>
Is there a way to get the text value of the selected option?
$('#my-select').val();
gives me 2, i want to get This is Two instead.
How?
What you want is
Get the selector for finding the selected option in the select box
Use .text() on the selector.
$('#my-select option:selected').text();

My code dynamically generates the options for the select element but the exact value of the options are unknown at the moment of creation.
So was playing around to set the selected value of my select element to the first child but was unable to do so in 1 line.
I was able to it in 2 lines but I was wondering if something shorter is possible.
<select id="selectElement">
<option value="1">Optie 1</option>
<option value="2">Optie 2</option>
</select>
$("#selectElement").val($(this).children(":first").val());
It's worth noting that most browsers will automatically select that first option for you.
But if you need to do it for some reason: You're not far off at all, but this doesn't come from the first part of that line. Instead:
var select = $("#selectElement");
select.val(select.children(":first").val());
Or I find this simpler:
var select = $("#selectElement");
select.val(select[0].options[0].value);
Or using the selected property of the option instead:
$("#selectElement")[0].options[0].selected = true;
// or with more jQuery
$("#selectElement > option:first").prop("selected", true);
One method is using .eq() selector.It reduce the set of matched elements to the one at the specified index.
Please try this:
$(selectElement).val($('#selectElement option:eq(0)').val());
See reference here
If you want the shortest method please try this:
$("#selectElement").prop("selectedIndex", 0);
If you have only one element, you should find it (with # id selector), and the also use his selector to find the children.
Otherwise you could use (in case you also have more elements) use a class, and iterate it (the second script in the snippet)
edit
Without js, you could simply use the selected property of option to set as default when page loads.
$("#selectElement").val($("#selectElement").children("option:first").val());
$(".selectElement").each(function() {
$(this).val($(this).children("option:first").val());
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select id="selectElement">
<option value="1">Optie 1</option>
<option value="2">Optie 2</option>
</select>
<select class="selectElement">
<option value="21">Optie 21</option>
<option value="22">Optie 22</option>
</select>
<select>
<option selected value="321">Optie 321</option>
<option value="322">Optie 322</option>
</select>
You can achieve this by using :first
$(document).ready(function () {
$("#selectElement").val($("#selectElement option:first").val())
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<select id="selectElement">
<option value="1">Optie 1</option>
<option value="2">Optie 2</option>
</select>
No need to use JavaScript to set selected the first element of the options because html will do it for you:
<select id="selectElement">
<option value="1">Optie 1</option>
<option value="2">Optie 2</option>
</select>
I have a select list like
<select id="list">
<option value="">Select something</option>
<option value="1">Uno</option>
<option value="2">Two</option>
<option value="3">Trois</option>
</select>
And with jQuery I want to select the second option, get the value and put it into a hidden input.
Im doing it this way:
$('#IdOfTheInput').val( $($('#list option')[1]).attr('value'); );
But I don't know if there is a better way to do it, since is a really common thing and it smells suboptimal.
Thanks!
If what you want is to select the option by index then you can use .eq() and use .val()
$('#IdOfTheInput').val($('#list option').eq(1).val());
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<select id="list">
<option value="">Select something</option>
<option value="1">Uno</option>
<option value="2">Two</option>
<option value="3">Trois</option>
</select>
<input id="IdOfTheInput" />
you can use jQuery eq() selector.
$("inputSelector").val($("SelectSelector option:eq(1)").val());
Use the options and value to get the value.
var option = document.getElementById("list").options[1].value; // return 1"
There's this website that I want to change how they display their dropdown menu.
http://i.stack.imgur.com/Wu718.jpg
I wanted to make it so that the default value is "Items for Sale", instead of "Forum Topics"
Here's their source code.
<select name="sec" style="margin-top:5px;width:138px;">
<option value="topics">Forum Topics</option>
<option value="s">Items for Sale</option>
<option value="b">Want to Buys</option>
<option value="users">Members</option>
</select>
Since I don't really care about how it looks, I just want to change the value="topics" to value="s" even without changing the texts.
I've read some tutorials, but they mostly use IDs and Classes as a selector, in this case, how do I target this Select from many other in their website and change the value.
You can use:
$('select[name=sec]').val('s');
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.3/jquery.min.js"></script>
<select name="sec" style="margin-top:5px;width:138px;">
<option value="topics">Forum Topics</option>
<option value="s">Items for Sale</option>
<option value="b">Want to Buys</option>
<option value="users">Members</option>
</select>
I think this is what you're describing in the comments below:
var dropdown = $('select[name=sec]');
// change the s option to items
dropdown.find('option[value=s]').attr('value', 'items');
// change the topics option to s
dropdown.find('option[value=topics]').attr('value', 's');
// change the dropdown's value to s
// (first option should continue to be selected because its value is now s)
dropdown.val('s');
// (this is for demo purposes only)
dropdown.after($("<div>").text("New HTML is: " + dropdown[0].outerHTML));
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.3/jquery.min.js"></script>
<select name="sec" style="margin-top:5px;width:138px;">
<option value="topics">Forum Topics</option>
<option value="s">Items for Sale</option>
<option value="b">Want to Buys</option>
<option value="users">Members</option>
</select>
You can use the name or any other attribute.
for css
select[name="sec"]
or jquery
$('select[name="sec"]').
DEMO inspect element from your browser to see the changes
you can select a select dropdown list with select[name=sec] and select the first option with option:first
$('select[name=sec] option:first').val('s');
and if you need to change any of options just use .eq()
$('select[name=sec] option').eq(0).val('s'); // eq(0) for the first option element . eq(1) for the second option element ...
If you want to make selected an other option use this code:
$('select[name="sec"]').find('option:selected').removeAttr('selected');
$('select[name="sec"]').find('option[value="s"]').attr('selected','selected');
This script removes the default selection (the first option) and select the option which has "s" value. For the Demo:
$('select[name="sec"]').find('option:selected').removeAttr('selected');
$('select[name="sec"]').find('option[value="s"]').attr('selected','selected');
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.3/jquery.min.js"></script>
<select name="sec" style="margin-top:5px;width:138px;">
<option value="topics">Forum Topics</option>
<option value="s">Items for Sale</option>
<option value="b">Want to Buys</option>
<option value="users">Members</option>
</select>
You have to find this element in the DOM. For this you should find the first parent container element of the which has ID or CLASS attribute. From that element you can create a search for the element what you want by using the .find() method.
If there're more element which has name attribute with "sec" value you should build a chain of find which separate that you want. For that you can use these function templates:
$(#CONTAINER_ID).find(.SUBCONTAINER_CLASS).find(ELEMENT_TYPE);
$(#CONTAINER_ID).find(SUBCONTAINER_TYPE).find(OTHER_SUBCONTAINER_TYPE:eq(X));
I am trying to select an option in a select menu that contains an optgroup. I have tried
document.getElementsByName("dob_year")[0].selectedIndex = "1980"; and it seems to work with select menus that contain no "optgroups", bit it does work with them. How can I select the "1980" option?
<select name="dob_year">
<optgroup label="Morning">
<option value="1980">80</option>
<option value="1981">81</option>
<option value="1982">82</option>
<option value="1983">83</option>
</optgroup>
</select>
As the name suggest, the selectedIndex is an index.
So you have to use the following:
document.querySelector('select').selectedIndex = 2;
Working jsfiddle: http://jsfiddle.net/vkSKy/
Take the below HTML select for an example:
<select name="selValues" id="selValues">
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">5</option>
<option value="4">3</option>
</select>
If we write the following jQuery statement:
$('#selValues').val('2'); // Two will get selected
$('#selValues').val('3'); // 3 will get selected instead of 5??
Why is it like that?
Use
$("#selValues option[value='3']").attr('selected', 'selected');
Also a good article on
jQuery - Select elements - tips and tricks
The val() method gets or sets the selected text. You may want to use selectedIndex instead:
$('#selValues').get(0).selectedIndex=2;
When selecting options jQuery looks first at the value then at the text of an option. It also goes through options in order. So, $('#selValues').val('3') selects options 3 first, but right after that changes selection to option 4 (as it has the text "3"). Use a multiple select to see that in fact both options are selected
<select name="selValues" id="selValues" multiple="multiple">
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">5</option>
<option value="4">3</option>
</select>
As of JQuery 1.4 this has now been made unambiguous. It will now select by value, not by text value http://jquery14.com/day-01#backwards
If you do need to still select by value then a suggested method is here
