I am learning spring mvc rest programming and got stuck at the below issue.
I have an item page in JSP which is used for adding a new item as well as editing an item.
What I did here is (not sure if this is the right approach), I have a controller method
#RequestMapping(value = "/item/{id}", method = RequestMethod.GET)
public String addEditItem(Model model, Principal principal, #PathVariable("id") String id) {
model.addAttribute("id", id);
model.addAttribute("item", new Item());
if (Integer.parseInt(id) != 0) {
model.addAttribute("edit", true);
} else {
model.addAttribute("edit", false);
}
System.out.println(model.toString());
return "item";
}
which determines if it is an add/ edit call and accordingly sets the value of booleanedit.
Below given is my item.jsp page.
<%# page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<%# taglib prefix="sf" uri="http://www.springframework.org/tags/form"%>
<%# taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<script type="text/javascript">
var itemurl = "";
function onDelete(event) {
var doDelete = confirm("Are you sure you want to delete this offer?");
if (doDelete == false) {
event.preventDefault();
}
}
function onReady() {
$("#delete").click(onDelete);
}
$(document).ready(onReady);
function updateItemDetails(item) {
$("#itemName").val(item.itemName);
$("#taxPercentage").val(item.taxPercentage);
$("#price").val(item.price);
$("#count").val(item.count);
}
function updatePage(itemurl) {
$.getJSON("<c:url value='${itemurl}'/>", updateItemDetails);
}
</script>
<c:if test="${edit}">
<c:set var="itemurl" value="/getitem/${id}"></c:set>
<c:out value="${itemurl}" />
<script type="text/javascript">
updatePage(itemurl);
</script>
</c:if>
<sf:form method="put"
action="${pageContext.request.contextPath}/saveitem" commandName="item">
<sf:input type="hidden" name="itemId" path="itemId" />
<table class="formtable">
<tr>
<td class="label">Item Name :</td>
<td><sf:input class="control" path="itemName" name="itemName"
id="itemName" type="text" />
<div class="error">
<sf:errors path="itemName"></sf:errors>
</div></td>
</tr>
<tr>
<td class="label">Tax Percentage :</td>
<td><sf:input class="control" path="taxPercentage"
name="taxPercentage" id="taxPercentage" type="text" />
<div class="error">
<sf:errors path="taxPercentage"></sf:errors>
</div></td>
</tr>
<tr>
<td class="label">Price :</td>
<td><sf:input class="control" path="price" name="price"
id="price" type="text" />
<div class="error">
<sf:errors path="price"></sf:errors>
</div></td>
</tr>
<tr>
<td class="label">Count :</td>
<td><sf:input class="control" path="count" name="count"
id="count" type="text" />
<div class="error">
<sf:errors path="count"></sf:errors>
</div></td>
</tr>
<tr align="center">
<td colspan="2"><input class="control" value="Save offer"
type="submit" /> <c:if test="${item.itemId != 0}">
<input name="delete" class="control" value="Remove offer"
type="submit" id="delete" />
</c:if></td>
</tr>
</table>
</sf:form>
Above the form I have added a <c:out> to see what url is being formed.
The rest method being used is,
#RequestMapping(value = "/getitem/{id}", method = RequestMethod.GET, produces="application/json")
#ResponseBody
public Item getItem(#PathVariable("id") String id) {
Item item = itemsService.getItem(Integer.parseInt(id));
return item;
}
The issue is that, if i make a url request with a particular id, in the <c:out value="${itemurl}" /> the correct url is shown, but the form is poulated with item details from the previous url request.
What could be the reason? Could you point out what i'm doing wrong here?

I am creating one JSP page in which there is a textfield and button. If user enters some integer value lets say 2 in textfield, then 2 rows will be appended in Html table at last. So the rows of HTML table are being created dynamically.
I am implementing this using ajax call to a page which has <tr> data which is to be added to the main table after last row.
Everything is working fine. Rows are created dynamically using ajax call. But the problem is that all rows added to table have same column name attributes.
Below is my code:
main JSP page:
<%# page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
<style>
.table {
font-size: 11px;
}
#dailyTableDiv {
height: 70%;
overflow: scroll;
}
</style>
<script>
function addTask(){
var n=$("#dailytsks").val();
for(i=1;i<=n;i++){
$.ajax({url:"employeeSection/dailyTableRow.jsp",success:function(result){
$('#dailyTable tr:last').after(result);
}});
}
//------------------------------
// i am trying this code to set different names for different select box column.
//but this is not happenting.
for(i=1;i<=n;i++){
$("#chSelect").attr("name","chSelect"+i);
}
//------------------------------
}
function add1Row(){
$.ajax({url:"employeeSection/dailyTableRow.jsp",success:function(result){
$('#dailyTable tr:last').after(result);
}});
}
</script>
</head>
<body>
<div class="container-fluid">
<div class="well">
<input type="text" id="dailytsks" name="dailytsks" /><input
type="button" name="addTsks" value="add" onclick="addTask();" /> <span

id="add1" name="add1" onclick="add1Row();" /> <span

<td><textarea name="comment" rows="3" cols="10"></textarea></td>
</tr>
here all columns have same name which is wrong.
how can I make unique name attribute pairs for the column in rows which are added. Currently, as seen in the code I am only trying to set unique name attribute values to Select column only. But I am not able to do.
I want something like:
if name of column is "chSelect" then for two rows, it should become as :
chSelect1 & chSelect2, respectively.
This might help you
HTML:-
<input type="checkbox" name="chSelect" class="chSelect" />
<input type="checkbox" name="chSelect" class="chSelect" />
<input type="checkbox" name="chSelect" class="chSelect" />
JAVASCRIPT:-
var i = 0;
$('.chSelect').each(function () {
$(this).attr('name', "chSelect"+i);
i++;
});

The basic idea is to store the row number in a global variable that you'll increase each time you add a row via Ajax.
When your Ajax calls resolve, you parse the resulting html (result) using JQuery, change the name property of the chSelect element, and append the change to the last tr as you did previously:
// add a global variable to store row number
var row = 0;
function addTask(){
var n = $("#dailytsks").val();
var max = parseInt(n);
for(i=1; i<=max; i++){
$.ajax({
url: "employeeSection/dailyTableRow.jsp",
success: function(result){
row += 1
var newName = "chSelect" + row;
var html = $('<div>').append(result);
$(html).find("#chSelect").attr("name", newName)
$('#dailyTable tr:last')
.after( html.html() )
}
});
}
}
function add1Row(){
$.ajax({
url: "employeeSection/dailyTableRow.jsp",
success: function(result){
row += 1;
var newName = "chSelect" + row;
var html = $('<div>').append(result);
$(html).find("#chSelect").attr("name", newName)
$('#dailyTable tr:last')
.after( html.html() )
}
});
}

try to put an extension to your form action="insert_product" ... like .php or .asp .. Also, reform your title to something more like "Object not found on form submit."
Try this:
<form method="post" enctype="multipart/form-data">
Ther are two problems:-
The problem is you write form contains only submit button.Try to remove <form method="post">before button
You write all your code in same page but in form your action is insert_product which have no extension like .php.It's totally wrong
so try to do any one of these two.
a) either define it action= insert_product.php and make a file with that name and put your last form processing code in that file.
b) Or remove form action attribute and write like <form method="post" enctype="multipart/form-data">.
Try 1 point and 2 nd b) point at-once. And check once.

example:
public ActionResult Index(string RoleID, array[] collChecbox) contents of collChecbox = { 'chkinsert-1','chkupdate-2'} in accordance with the user checked of checkbox input.
can somebody help me??
Why don't you use Ajax.BeginForm() this makes so easy to send posted form value.
Also, you should create proper model first.
MODEL
public class UserRole
{
public Administrator Administrator { get; set; }
public FreeUser FreeUser { get; set; }
}
public class Administrator
{
public int Checkbox1 { get; set; }
}
public class FreeUser
{
public int Checkbox1 { get; set; }
}
Do following in View.
#model Model.UserRole
<div id="result"></div>
#using (Ajax.BeginForm(new AjaxOptions { UpdateTargetId = "result" }))
{
<input type="hidden" name="RoleID" value="1" id="RoleID" />
<table id="mytable">
<tr>
<td>View</td>
<td>Insert</td>
<td>Update</td>
<td>Delete</td>
</tr>
<tr>
<td>Administrator</td>
<td>
#Html.CheckBoxFor(m => m.Administrator.Checkbox1)
</td>
</tr>
<tr>
<td>Free User</td>
<td>
#Html.CheckBoxFor(m => m.FreeUser.Checkbox1)
</td>
</tr>
</table>
<br />
<button type="submit" class="buttons buttons-style-1" onclick="Save()">Save</button>
}
Controller action
[HttpPost]
public ActionResult Index(UserRole model)
{
return View();
}
Also don't forget to include ajax library.
<script src="#Url.Content("~/Scripts/jquery.unobtrusive-ajax.js")" type="text/javascript"></script>
I using a simple form where I'm validating a user login. Where I want to pass user name in my javascript POPUP for every successful login. For now it is only displaying Hello .I'm using concatination operator but no luck.
this is what my Javascript looks like
<script language="javascript">
function show()
{
var n = document.getElementById("uname").value;
alert("Hello "+n);
return false;
}
function noshow()
{
alert("Invalid Login");
return false;
}
</script>
HTML & Asp code
<form method="post" name="myform">
<table border="0" width="100%" cellpadding="0" cellspacing="0">
<tr>
<td>User Name:</td>
<td><input type="text" name="uname" value="" /></td>
</tr>
<tr>
<td>Password:</td>
<td><input type="password" name="pass" value="" /></td>
</tr>
<tr>
<td colspan="2" align="center">
<input type="submit" value="Login" name="sub" />
<input type="reset" value="Clear" />
</td>
<%
if Request.Form("sub") <> "" then
sql="select * from login_tbl where u_name = '" & Request.Form("uname") & "' AND pass= '" & Request.Form("pass") & "'"
rs.Open sql,con,1,2
if rs.Eof then
Response.Write("<script language='javascript'>noshow();</script>")
else
'Response.Redirect("http://www.google.com")
Response.Write("<script language='javascript'>show();</script>")
end if
rs.Close
end if
%>
</tr>
</table>
</form>
You just need to do something like this:
<td><input type="text" id="uname" name="uname" value="<% Response.Write(Request.Form("uname")) %>" /></td>
After you submit a form, uname became empty, and you need to restore value of uname element on server.
Also, you are using document.getElementById(), but your uname element has no id. So it will find nothing. In order to avoid that, you need to add id to that input (like in my code above).
But in this case uname will show username after form is submitted. If you do not need that, you can do something like this:
<%
if Request.Form("sub") <> "" then
sql="select * from login_tbl where u_name = '" & Request.Form("uname") & "' AND pass= '" & Request.Form("pass") & "'"
rs.Open sql,con,1,2
if rs.Eof then
Response.Write("<script language='javascript'>noshow();</script>")
else
'Response.Redirect("http://www.google.com")
Response.Write("<script language='javascript'>show('" & Request.Form("uname") & "');</script>")
end if
rs.Close
end if
%>
and update your function like this:
function show(n)
{
alert("Hello "+n);
return false;
}
