Making the option as selected based on the specfic value

[sivaani]

hai friends

i am doing my updating page their i have one select field i am getting the input from the user and saved the select field value alone in the db . now based on the select value from the db the select field option should be displayed in the page .that means the option displayed on the page should change based on the db value . how can i change based on the db value as selected in the select field?.

thanks in advance

assuming you have a select like the following:

[HTML]<select id="my_select">
<option value="A">A</option>
<option value="B">B</option>
<option value="C">C</option>
</select>
[/HTML]
you could use a function like this:

function select_opt_by_val(obj, val) {
    var opts = obj.getElementsByTagName('option');
 
    for (var i = 0, n; n = opts[i]; i++) {
        if (n.value == val) {
           n.selected = true;
           break;
        }
    }
}
 
var s = document.getElementById('my_select');
 
select_opt_by_val(s, 'C');
 

kind regards
