How to get the values of a dropdown multi select list in a JSP page
Question
I created a dropdown multi select list using javascript function which is as follows
function addRow() {
$(function() {
$('#lstFruits').multiselect({
includeSelectAllOption : true
});
});
var table = document.getElementById('my_table'); //html table
var rowCount = table.rows.length; //no. of rows in table
var columnCount = table.rows[0].cells.length; //no. of columns in table
var row = table.insertRow(rowCount); //insert a row
var cell1 = row.insertCell(0); //create a new cell
var element1 = document.createElement("input"); //create a new element
element1.type = "checkbox"; //set the element type
element1.setAttribute('id', 'newCheckbox'); //set the id attribute
element1.setAttribute('checked', true); //set checkbox by default checked
cell1.appendChild(element1); //append element to cell
var cell2 = row.insertCell(1);
var element2 = document.createElement("input");
element2.type = "text";
element2.setAttribute('id', 'newInput'); //set the id attribute
element2.setAttribute('name', 'sl' + rowCount);
element2.setAttribute('style', 'width: 50px');
cell2.appendChild(element2);
var cell3 = row.insertCell(2);
var element3 = document.createElement("input");
element3.type = "textarea";
element3.setAttribute('rows', '4');
element3.setAttribute('cols', '40');
element3.setAttribute('id', 'newInput'); //set the id attribute
element3.setAttribute('name', 'discription' + rowCount);
cell3.appendChild(element3);
var cell4 = row.insertCell(3);
var element4 = document.createElement("input");
element4.type = "text";
element4.setAttribute('id', 'newInput'); //set the id attribute
element4.setAttribute('name', 'quantity' + rowCount);
cell4.appendChild(element4);
var cell5 = row.insertCell(4);
var element5 = document.createElement("input");
element5.type = "text";
element5.setAttribute('id', 'newInput'); //set the id attribute
element5.setAttribute('name', 'price' + rowCount);
cell5.appendChild(element5);
var cell6 = row.insertCell(5);
var element6 = document.createElement("input");
element6.type = "text";
element6.setAttribute('id', 'newInput'); //set the id attribute
element6.setAttribute('name', 'CST' + rowCount);
element6.setAttribute('style', 'width: 50px');
cell6.appendChild(element6);
var cell7 = row.insertCell(6);
var element7 = document.createElement("select");
element7.type = "select";
element7.setAttribute('multiple', 'multiple');
// element7.setAttribute('style', 'width: 50px');
element7.setAttribute('size', 3);
element6.setAttribute('id', 'newSelect'); //set the id attribute
element6.setAttribute('name', 'taxGroup' + rowCount);
var option1 = document.createElement("option");
var option2 = document.createElement("option");
var option3 = document.createElement("option");
var option4 = document.createElement("option");
var option5 = document.createElement("option");
var option6 = document.createElement("option");
var option7 = document.createElement("option");
var option8 = document.createElement("option");
option1.text = "Select Tax";
option2.text = "VAT5";
option3.text = "VAt14.5";
option4.text = "SALES TAX";
option5.text = "SERVICE TAX";
option6.text = "KISHI Kalyan";
option7.text = "Swachh BHARAT";
option8.text = "GST";
element7.add(option1);
element7.add(option2);
element7.add(option3);
element7.add(option4);
element7.add(option5);
element7.add(option6);
element7.add(option7);
element7.add(option8);
cell7.appendChild(element7);
}
Now my question is:
How to get the selected values to another jsp page.
I tried the code but the code is not working well.
So i am posting the code so that if any changes required you can say to me.
The code is as follows
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<%@ page import="java.io.*"%>
<%@ page import="java.sql.*"%>

for multi select drop down use:
<select name="ur_name[]"></select>
name="ur_name[]" will make it an array. When its containing form is submitted you will get the selected array like
ur_name[0] = first element, ur_name[1] = second element and so on.
