Manipulate two selects on page load with jQuery
Let’s say the following is our first select −
<select name="all_name" id="all_present_name"> <option value="John">John</option> <option value="David">David</option> <option value="Bob">Bob</option> <option value="Mike">Mike</option> <option value="Sam">Sam</option> <option value="Carol">Carol</option> </select>
Following is our second select −
<select name="common_name" id="remaining_name"> <option value="David">David</option> <option value="Mike">Mike</option> <option value="Carol">Carol</option> </select>
We need to remove the options in the first select, which are similar to options in the second select. For this, use val(). Following is the complete code −
Example
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Document</title> </head> <link rel="stylesheet" href="//code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css"> <script src="https://code.jquery.com/jquery-1.12.4.js"></script> <script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script> <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.min.css"> <body> <select name="all_name" id="all_present_name"> <option value="John">John</option> <option value="David">David</option> <option value="Bob">Bob</option> <option value="Mike">Mike</option> <option value="Sam">Sam</option> <option value="Carol">Carol</option> </select> <select name="common_name" id="remaining_name"> <option value="David">David</option> <option value="Mike">Mike</option> <option value="Carol">Carol</option> </select> </body> <script> $('#remaining_name > option').each(function (i, el) { var value = $(el).val(); $('#all_present_name > option[value="' + value + '"]').remove(); }); </script> </html> Output
The output is as follows −
