通过使用Ajax通过PHP从数据库中获取数据来进行预选择

Question

I have a select tag, which option values come from a database via PHP using ajax. The previously selected value is saved in the DB.

I want to display a select showing the previously selected value (which is saved in the DB).

This is the HTML code

<select id='country'></select>

This is the JS code (ajax getting all country list)

$.ajax({
    url: 'country.php',
    scriptCharset: 'ANSI',              
    success:function(result) {
        $('#country').append(result);
    }
});

Let's say I want to show country which value is 27, how can I achieve that?

Answer 1

$.ajax({
url:"country.php",              
scriptCharset: 'ANSI' ,             
success:function(result){       
    $('#country').append(result);

    // Have you tried add this???
    $('#country').val(27);

   }
});

Answer 2

使用选项进行另一个选择，然后在js中，您可以使用onchange重新加载国家/地区列表。

Answer 3

$.ajax({
url:"country.php",
scriptCharset: 'ANSI' ,
success:function(result){
$ ('#country').append(result);
$ ('#country').val(VALUE);
} });
