Spring AutoPopulatingList not binding to modelAttribute - javascript

I am creating a application that could dynamically add rows to my html/jsp page and when clicked submit, data will be saved on the database. I am using javascript in order to add rows dynamically.When I enter data and hit submit , my modelAttribute does not bind to the fields in form page. To avoid array Index out of bound exception made use of autopopulating list.
Below is the form page
<%# page language="java" contentType="text/html; charset=ISO-8859-1"

var counts = rowCount - 1;

Anyhelp on this will be appreciated.

You had some typos, try now and remember that on server side you receive keys-values for each cell of the table, so appropriate processing is most likely needed.
EDIT:
That's beacause your IncidentForm leaves something to be desidered, as I already told you keep in mind that:
on server side you receive keys-values for each cell of the table, so
appropriate processing is most likely needed.
If you are getting exception that means that you have to correct the way you are processing those keys-values.

How to insert particular cell values of HTML table in TextBoxes using JavaScript?

I have a HTML form. The save and delete button are working fine. But I want to write JavaScript (not jQuery or AngularJS) code of edit and update button. When I click the edit the data of particular row should be displayed in the textboxes and when I press update button the updated data of that particular row should get submitted in the HTML table.
function addRow() {
var id= document.getElementById("id");
var name= document.getElementById("name");
var gender= document.getElementById("gender");
var address= document.getElementById("address");
var email = document.getElementById("email");
var table = document.getElementById("myTableData");
var rowCount = table.rows.length;
var row = table.insertRow(rowCount);
row.insertCell(0).innerHTML= id.value;
row.insertCell(1).innerHTML= name.value;
row.insertCell(2).innerHTML= gender.value;
row.insertCell(3).innerHTML= address.value;
row.insertCell(4).innerHTML= email.value;
row.insertCell(5).innerHTML= '<input type="button" value = "Delete" onClick="Javacsript:deleteRow(this)">';
row.insertCell(6).innerHTML= '<input type="button" value = "Edit" onClick="Javacsript:updateRow(this)">';
id.value="";
name.value="";
gender.value="";
address.value="";
email.value="";
}
function updateRow(obj){
}
function reset(){
var id= document.getElementById("id");
var name= document.getElementById("name");
var gender= document.getElementById("gender");
var address= document.getElementById("address");
var email = document.getElementById("email");
var table = document.getElementById("myTableData");
id.value="";
name.value="";
gender.value="";
address.value="";
email.value="";
}
function deleteRow(obj) {
var index = obj.parentNode.parentNode.rowIndex;
var table = document.getElementById("myTableData");
table.deleteRow(index);
}
}
Add Function will look like this..
function addRow() {
var table = document.getElementById("myTableData");
var rowCount = table.rows.length;
var row = table.insertRow(rowCount);
var id = document.getElementById("id");
var name = document.getElementById("name");
var gender = document.getElementById("gender");
var address = document.getElementById("address");
var email = document.getElementById("email");
var cell1 = row.insertCell(0);
cell1.innerHTML=id.value;
var cell2 = row.insertCell(1);
cell2.innerHTML = name.value;
var cell3 = row.insertCell(2);
cell3.innerHTML = gender.value;
var cell4 = row.insertCell(3);
cell4.innerHTML = address.value;
var cell5 = row.insertCell(4);
cell5.innerHTML = email.value;
var cell6 = row.insertCell(5);
var strHtml5 = "<INPUT TYPE=\"Button\" CLASS=\"Button\" onClick=\"UpdateRow(" + rowCount + ")\" VALUE=\"Update Row\">|<INPUT TYPE=\"Button\" CLASS=\"Button\" onClick=\"delRow(" + rowCount + ")\" VALUE=\"Delete Row\">";
cell6.innerHTML = strHtml5;
}

I copied your code and executed in my machine and found minor errors as well as big mistake you did by not using form tag and created the form.
After reverse engineering I appended your code and made it fully functional as well as simple to understand.

Dynamic Rows and Table

I am trying to implement a dynamic table but when the button is pressed to add a row the row is added but the input text box is not inserted in both cells. Any idea how to solve this problem.
<html>
<body>
<input type="button" value="Add Row" onclick="addRow('dataTable')" />
<table id="dataTable" width="150px" border="1">
<tr>
<td height="27">
1
</td>
<td>
<input type="text" />
</td>
<td>
<input type="text" />
</td>
</tr>
</table>
</body>
</html>
<script type="text/javascript">
function addRow(tableID) {
var table = document.getElementById(tableID);
var rowCount = table.rows.length;
var row = table.insertRow(rowCount);
var firstCell = row.insertCell(0);
firstCell.innerHTML = rowCount + 1;
var secondCell = row.insertCell(1);
var thirdCell = row.insertCell(2);
var element = document.createElement("input");
element.type = "text";
element.name = "txtbox[]";
secondCell.appendChild(element);
}
</script>
You need to add another "input" element and append this into the thirdCell.
Try changing the last bit of your javascript function to this:
var element1 = document.createElement("input");
element1.type = "text";
element1.name = "txtbox1[]";
var element2 = document.createElement("input");
element2.type = "text";
element2.name = "txtbox2[]";
secondCell.appendChild(element1);
thirdCell.appendChild(element2);
Shown here
Note: Your script tag should go inside the body of the html.
Here is what the final code could look like:
<html>
<body>
<input type="button" value="Add Row" onclick="addRow('dataTable')" />
<table id="dataTable" width="150px" border="1">
<tr>
<td height="27">
1
</td>
<td>
<input type="text" />
</td>
<td>
<input type="text" />
</td>
</tr>
</table>
<script type="text/javascript">
function addRow(tableID) {
var table = document.getElementById(tableID);
var rowCount = table.rows.length;
var row = table.insertRow(rowCount);
var firstCell = row.insertCell(0);
firstCell.innerHTML = rowCount + 1;
var secondCell = row.insertCell(1);
var thirdCell = row.insertCell(2);
var element1 = document.createElement("input");
element1.type = "text";
element1.name = "txtbox1[]";
var element2 = document.createElement("input");
element2.type = "text";
element2.name = "txtbox2[]";
secondCell.appendChild(element1);
thirdCell.appendChild(element2);
}
</script>
</body>
</html>
You have not written the code to add a new text element to the third column. Add the below mentioned code after "secondCell.appendChild(element);" section of your code:
var element2 = document.createElement("input");
element2.type = "text";
element2.name = "txtbox2[]";
thirdCell.appendChild(element2);

can not access the dynamically created textbox value in servlet getting null value as output
