Delete data dynamically with JSP and servlet (Very Urgent)
843838Jun 6 2007 — edited Jun 18 2007Hi,
I am new with servlets and JSP. On my jsp page I am populating customer names in a drop box from database and I have 3 buttons ADD, DELETE and EDIT.
Now when I press DELETE buttong I am calling delete function which is writen in Javascript on my jsp file only,now I want to pass these selcted values ehich I have stored in an array to be pass to servlet,so I can write Delete query for it and delete.
Could anyone help with sample code>
Here what I am trying to say:
<HTML>
<HEAD>
<script language="JavaScript" type="text/javascript">
<!--
function remove()
{
var u = confirm("Are you sure you want to Delete Selected names?")
if (u==true)
{
var selectedArray = new Array();
var selObj = document.getElementById('CUSTOMER_NAME');
var i;
var count = 0;
for (i=0; i<selObj.options.length; i++) {
if (selObj.options.selected) {
selectedArray[count] = selObj.options[i].value;
count++;
}
}
alert("names to be deleted are:"+selectedArray);
// selectedArray has the selected items stored
alert("Items Deleted!")
}
else
{
alert("No data were deleted!!You pressed Cancel!")
}
}
//-->
</script>
</HEAD>
<BODY>
//calling servlet on action tag of form
<FORM METHOD= 'POST' ACTION='Remove_Customer'>
<form ><INPUT TYPE='submit' NAME='DELETE' VALUE='DELETE' onclick="remove()"></TD></form>
<form><INPUT TYPE='submit' NAME='MODIFY' VALUE='MODIFY' onclick="modification()" ></TD></form>
</BODY>
</HTML>
PLEASE HELPME,it's very urgent.
Since the selected Array is in javascrip language , I don't know how can I pass that to servlet.
request.getParameter is not working,since it's an array
Many thanks in Advance.
