How do I make the first option of
Jquery Solutions
Solution 1 - Jquery
$("#target").val($("#target option:first").val());
Solution 2 - Jquery
You can try this
$("#target").prop("selectedIndex", 0);
Solution 3 - Jquery
// remove "selected" from any options that might already be selected
$('#target option[selected="selected"]').each(
function() {
$(this).removeAttr('selected');
}
);
// mark the first option as selected
$("#target option:first").attr('selected','selected');
Solution 4 - Jquery
When you use
$("#target").val($("#target option:first").val());
this will not work in Chrome and Safari if the first option value is null.
I prefer
$("#target option:first").attr('selected','selected');
because it can work in all browsers.
Solution 5 - Jquery
Changing the value of the select input or adjusting the selected attribute can overwrite the default selectedOptions property of the DOM element, resulting in an element that may not reset properly in a form that has had the reset event called.
Use jQuery's prop method to clear and set the option needed:
$("#target option:selected").prop("selected", false);
$("#target option:first").prop("selected", "selected");
Solution 6 - Jquery
$("#target")[0].selectedIndex = 0;
Solution 7 - Jquery
One subtle point I think I've discovered about the top voted answers is that even though they correctly change the selected value, they do not update the box on Chrome desktop, so this may not be the case everywhere).
Solution 8 - Jquery
If you have disabled options, you may add not([disabled]) to prevent selecting them which results into the following:
$("#target option:not([disabled]):first").attr('selected','selected')
Solution 9 - Jquery
Another way to reset the values (for multiple selected elements) could be this:
$("selector").each(function(){
/*Perform any check and validation if needed for each item */
/*Use "this" to handle the element in javascript or "$(this)" to handle the element with jquery */
this.selectedIndex=0;
});
Solution 10 - Jquery
$('#newType option:first').prop('selected', true);
Solution 11 - Jquery
This worked for me!
$("#target").prop("selectedIndex", 0);
Solution 12 - Jquery
I've found that just setting attr selected doesn't work if there's already a selected attribute. The code I use now will first unset the selected attribute, then select the first option.
$('#target').removeAttr('selected').find('option:first').attr('selected', 'selected');
Solution 13 - Jquery
Simple like that:
$('#target option:first').prop('selected', true);
Solution 14 - Jquery
Here is how I would do it:
$("#target option")
.removeAttr('selected')
.find(':first') // You can also use .find('[value=MyVal]')
.attr('selected','selected');
Solution 15 - Jquery
Although the each function probably isn't necessary ...
$('select').each(function(){
$(this).find('option:first').prop('selected', 'selected');
});
works for me.
Solution 16 - Jquery
It only worked for me using a trigger('change') at the end, like this:
$("#target option:first").attr('selected','selected').trigger('change');
Solution 17 - Jquery
If you are going to use the first option as a default like
<select>
<option value="">Please select an option below</option>
...
then you can just use:
$('select').val('');
It is nice and simple.
Solution 18 - Jquery
For me it only worked when I added the following code:
.change();
For me it only worked when I added the following code: As I wanted to "reset" the form, that is, select all the first options of all the selects of the form, I used the following code:
$('form').find('select').each(function(){ $(this).val($("select option:first").val()); $(this).change(); });

Solution 20 - Jquery
On the back of James Lee Baker's reply, I prefer this solution as it removes the reliance on browser support for :first :selected ...
$('#target').children().prop('selected', false);
$($('#target').children()[0]).prop('selected', 'selected');
Solution 21 - Jquery
For me, it only worked when I added the following line of code
$('#target').val($('#target').find("option:first").val());
Solution 22 - Jquery
$("#target").val(null);
worked fine in chrome
Solution 23 - Jquery
If you're storing the jQuery object of the select element:
var jQuerySelectObject = $("...");
...
jQuerySelectObject.val(jQuerySelectObject.children().eq(0).val());
Solution 24 - Jquery
Check this best approach using jQuery with ECMAScript 6:
$('select').each((i, item) => {
var $item = $(item);
$item.val($item.find('option:first').val());
});
Solution 25 - Jquery
You can select any option from dropdown
by using it.
// 'N' can by any number of option. // e.g., N=1 for first option
$("#DropDownId").val($("#DropDownId option:eq(N-1)").val());
Solution 26 - Jquery
$('select#id').val($('#id option')[index].value)
Replace the id with particular select tag id and index with particular element you want to select.
i.e.
<select class="input-field" multiple="multiple" id="ddlState" name="ddlState">
<option value="AB">AB</option>
<option value="AK">AK</option>
<option value="AL">AL</option>
</select>
So here for first element selection I will use following code :
$('select#ddlState').val($('#ddlState option')[0].value)
Solution 27 - Jquery
var firstItem = $("#interest-type").prop("selectedIndex", 0).val();
console.log(firstItem)
Solution 28 - Jquery
Use:
alert($( "#target option:first" ).text());
