I want to set the 'selected'
attribute in a select option list with javascript/jquery. I have the select element in a jquery object, I just want to add the "selected" attribute to and item in the list.
$(mySelect).html()
looks like this;
<option value="LININGER LAKE">LININGER LAKE</option>
<option value="MOOREDALE LAKE">MOOREDALE LAKE</option>
<option value="CARTER LAKE">CARTER LAKE</option>
I need to find the "CARTER LAKE" option and add the selected attribute to it so the HTML looks like this
<option value="LININGER LAKE">LININGER LAKE</option>
<option value="MOOREDALE LAKE">MOOREDALE LAKE</option>
<option value="CARTER LAKE" selected="selected">CARTER LAKE</option>
I know this can't be that hard, I'm just having a brain fart!
使用jQuery Attribute Equals选择器 :
$(mySelect).find('option[value="CARTER LAKE"]').prop("selected", "selected");
Try .contains()
as shown
$("select option:contains('CARTER LAKE')").attr('selected','selected')
OR
$("select option:contains('CARTER LAKE')").prop('selected',true)
$('option[value="CARTER LAKE"]').prop( "selected" );
要么
$('option[value="CARTER LAKE"]').attr( "selected", "selected" );
As simple as $(mySelect).val('CARTER LAKE')
Try by attr()
$(document).ready(function(){ $('option[value="CARTER LAKE"]').attr( "selected", "selected" ); });
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <select> <option value="LININGER LAKE">LININGER LAKE</option> <option value="MOOREDALE LAKE">MOOREDALE LAKE</option> <option value="CARTER LAKE">CARTER LAKE</option> </select>
