Trying to serialize a form with dynamically generated input elements, but the element values are not being published
I am adding items dynamically. However, when I try and serialize the form, none of the dynamically generated items are serialized.
This is the function I am using to add elements to the page:
function addObjects(IDname,classname)
{
//to add more objects
var number;
switch(classname)
{
case "name":
number = no_Name++;
break;
case "part":
number = no_part++;
break;
}
var id = classname + number;
$("#"+IDname).append('<tr class="'+id+'"><td><input id="'+id+'" class="'+id+'" type="text"> <button class="'+id+'" onclick=removeAdditions("'+id+'")>x</button></td></tr>');
}
The page looks like this:
<html>
<head>
<script src="Controller.js" type="text/javascript"></script>
<script type="text/javascript" src="https://ajax.microsoft.com/ajax/jQuery/jquery-1.4.2.min.js"></script>
<script type="text/javascript">
//in order to prevent form reload when button click occurs
$(document).ready(function(){
document.getElementById("ReportForm").onsubmit = function (event) { event.preventDefault(); }
});
</script>
</head>
<body>
<div class="detailsPane" id="detailsPane1" >
<form id="ReportForm" name="ReportForm" >
<table style="width: 100%;">
<tbody>
<tr>
<td>
1. Describe the Status briefly-
</td>
<td>
<textarea id="StatDescp" name="StatDescp"></textarea>
</td>
</tr>
</tbody>
</table>
<br>
<table style="width: 100%;">
<thead>
<tr>
<th colspan="4" align="top">
Part Status
</th>
</tr>
</thead>
<tbody>
<tr>
<td style="vertical-align:top;">
Part Name:
</td>
<td style="vertical-align:top;">
<table >
<tbody id="PartName">
<tr class="partname0">
<td><input class="part_name" type="text"> <button onclick='addObjects("PartName","part_name");'>+</button></td>
</tr>
</tbody>
</table>
</td>
<tbody>
</table>
</form>
</div>
<div id="buttonDiv" >
<a class="bottomLeftResultDiv" id="messageBox"></a>
<input type="button" id="saveButton" value="Save" style="width:85px" onclick="save();" />
</div>
</body>
</html>
And finally here is the save button.
function save() {
var select = document.getElementById('newReportPane');
var contents = $('#ReportForm').serialize();
contents = contents.replace(/=on/g, "=checked");
contents = contents.replace(/\+/g, " ");
$("#messageBox").html("Saving report...");
console.log(contents);
$.post("/Report/Report1", { action: "save", content: contents }, function (data) {
if (data != "ACK")
$("#messageBox").html("Unable to save.");
else
$("#messageBox").html("Report saved successfully");
});
}
When I click the Save button it only publishes this one StatDescp=
without any dynamically generated items. I really can't figure out why. Any help would be appreciated.

Give an attribute name=
for each input you add.
From http://api.jquery.com/serialize/
For a form element value to be included in a serialized string, the element must have a name attribute.
