Easy question : SELECT and multiple selections

**eL_NiNo** · Jul 4th, 2001, 10:02 AM

Hi,

I'm using a select to display the result of a search. Now the user can select multiple rows and I'm opening a new page containing only those records.

What I want to know is how to determine which rows are selected since mydoc.myform.mylist.selectedindex only returns the index of the last selected item, same for value.

To get multiple values you have to loop through the options[] array and check the SELECTED property.

<html>
<head>
<title></title>
<script LANGUAGE = "JavaScript">
var buttonClicked = false;

function getRows(){

var intIndex;

for(intIndex = 0;intIndex < frmMain.sctNames.length;intIndex++){

if(frmMain.sctNames.options[intIndex].selected){
frmMain.txtResult.value += frmMain.sctNames.options[intIndex].index;
alert(frmMain.sctNames.options[intIndex].index);
}//end if

}//end for

}//end function

</script>
</head>
<body>
<form NAME = "frmMain">
<select NAME = "sctNames" MULTIPLE>
<option>Harry Henderson</option>
<option>John LeClair</option>
<option>Mario Lemieux</option>
<option>Jeremy Roenick</option>
</select>
<br>
<input TYPE = "text" NAME = "txtResult">
<br>
<input TYPE = "button" VALUE = "Get Rows" ONCLICK = "getRows();">
</form>
</body>
</html>

Ok, thanks for the reply Psyrus !

I tried your idea, but my Vbscript code doesn't work

Any idea wh'ats wrong with it ?

Code:

	Sub AddElem()
		Dim i
		Dim strRecherche
		
		With document.frmRechercher
			For i = 1 to <%= rs.RecordCount %>
				If .lstRechercher.options(i).selected Then
					strRecherche = strRecherche & .lstRechercher.options(i).value & "*!*"
				End if
			Next
		End With
		
		msgbox strRecherche
	End Sub

The array starts at 0 index so start your loop there. I think you have to change it to options[], maybe not in VBScript though.
