[thelist] re: Multiple Selects in asp / javascript

[Ormerod Mark]

Thanks for your help guys - I've done it (so far!) this way :

<script language="JavaScript">
	<!--
	var arrData = new Array();
<%
intCounter = 0
SQLString="sswr_sp_getpractices;"
set RSPractices = server.CreateObject("ADODB.Recordset")
	RSPractices.Open SQLString,strconnection,2,2
do until RSPractices.EOF
            %>arrData[<%=intCounter%>] = new
Array("<%=RSPractices("PracticeLocationID")%>","<%=RSPractices("PracticeID")
%>","<%=RSPractices("PracticeDetails")%>");
            <%
            intCounter = intCounter + 1
            RSPractices.MoveNext()
loop
RSPractices.Close()
set RSPractices = nothing
%>

function BindToCombo(strTargetCmbID, varFilterValue, arrData) {
            var objTargetCmb = document.getElementById(strTargetCmbID);
            //Reset combo box options
            for(var i=(objTargetCmb.length-1);i>=0;i=i-1) {
                        objTargetCmb.options[i] = null;
            }
            var objOption = new Option("Not Known","1");
            try        //Try adding it the microsoft way first - they do
have 80% of the browser market share!
                        {objTargetCmb.add(objOption);}
            catch(err) //Try it the proper way for more compliant browsers
                        {objTargetCmb.add(objOption, null);}
            for (var i=0; i<arrData.length; i++) {
                        if (arrData[i][0] == varFilterValue) {
                                    var objOption = new
Option(arrData[i][2],arrData[i][1]);
                                    try
 
{objTargetCmb.add(objOption);}
                                    catch(err)
                                                {objTargetCmb.add(objOption,
null);}
                                    }
                        }
            }
-->
</script>

The select which trigers the filer has an onchange as follows :

<select class="StandardForm" name="PracticeLocationID"
onchange="BindToCombo('PracticeID',this.value,arrData)">

The ID being the ID of the select we're binding to.

I'd like to get an "if" statement in there so that is the option select all
(value "all") is picked I can restore the select being changed to the
original state it is in on page load (show everything).

Thanks.
