Select Box 1

[JohannIcon]

I have a select box, which is retreiving items from a database. I want this select box initial value to blank and index of 0 like this:-

Response.Write (&quot;<OPTION VALUE=&quot;&quot;0&quot;&quot;></OPTION>&quot

Now how can I check that the user, after filling in the form, does not leave the select box empty but chooses an item from the list? I can remove this option and display the items directly, however I wish that the initial form is blank so that the user does not make a mistake and chooses the first option automatically or by mistake.

Thanks for your help

Give your select an id (for exemeple &quot;mySelect&quot and then, code this in your validation function :

var oSel = document.getElementById("mySelect");
if (oSel.selectedIndex==0) or (oSel.selectedIndex==-1)
  alert ("Choose one !!!");

Note that if only write that :

Response.Write (&quot;<OPTION VALUE=&quot;&quot;0&quot;&quot;></OPTION>&quot;)

your line won't be selected (oSel.selectedIndex will be -1). If you want to select an option in a select, write that :

Response.Write (&quot;<OPTION SELECTED VALUE=&quot;&quot;0&quot;&quot;></OPTION>&quot;)

I tried both but they did not work. This is my code:-

<select name=&quot;FilterSelection&quot; id=&quot;MySelect&quot;>

//check to see if select is empty
var oSel = document.getElementById(&quot;mySelect&quot;
if (oSel.selectedIndex==0) or (oSel.selectedIndex==-1)
{
alert(&quot;Please Choose a package!!&quot
return false
}

This code seems good to me except for the case of id wich is written &quot;MySelect&quot; at a place and &quot;mySelect&quot; at the other one. Try to correct that and, if it still don't work, post the full page. Water is not bad as long as it stays out human body ;-)

Go again in the good thread :
Try that :

<select name=&quot;FilterSupport&quot; id=&quot;FilterSupport&quot;>
<%
   ' no change to ASP code
%>
</select>

//check to see if support update Text is empty
var oSel = document.getElementById(&quot;FilterSupport&quot;);
if (oSel.selectedIndex==0) 
{
    alert(&quot;Please Choose a package!!&quot;);
    oSel.focus();
    oSel.select();
    return false;
}

if it doesn't work, give me the message and the line on wich the error occurs.

Oh it worked at last! However without the oSel.select() cause it told me that this object does not support this method or class

Thanks very much mate!
