[gits]

hi ...

use the onchange-event of the <select> - element to invoke a function with the value of the control:

<script type="text/javascript">
function show_value(val) {
    alert(val);
}
</script>
 
<select name="test" onchange="show_value(this.value);">
    <option value="a">a</option>
    <option value="b">b</option>
    <option value="c">c</option>
</select>

kind regards

Hallo guys

what if you have code like one below and want to use onselect

        <?php
 
              echo "<select name='states'  onclick='getClientData(this)' >\n";
              echo "<option value=''>==== choose title ====</option>\n";
              $result=mysql_db_query($db_name,"select `template_id`, `template_detail`,`template_desc` from tbl_templates ");
              while(list($id, $name,$detail)=mysql_fetch_array($result)){
                   echo "<option value=\"$id\" >$detail</option> \n" ;
              }
             echo "</select>\n";
 
            ?>

hi ...

please explain it in more detail ... what should happen? your current code always calls getClientData() when you click that control ... so what do you want to achieve instead or additionally?

kind regards

you can use this code i hope it will help for you.

<select id="ddlFruits" onchange="GetSelectedTextValue(this)">
    <option value=""></option>
    <option value="1">Apple</option>
    <option value="2">Mango</option>
    <option value="3">Orange</option>
</select>
<script type="text/javascript">
    function GetSelectedTextValue(ddlFruits) {
        var selectedText = ddlFruits.options[ddlFruits.selectedIndex].innerHTML;
        var selectedValue = ddlFruits.value;
        alert("Selected Text: " + selectedText + " Value: " + selectedValue);
    }
</script>

Thank you.

if the options do have a value property this solution is definitivly inferior because of the many more operations and the solution i gave in post #2 is the one to prefer.
