I have a jsp page which is
"addSource.jsp"
present in eclipse as shown in the picture.
Now my question is i have a javascript function where i have to give "addSource.jsp" in it so that it can move to that page from the current jsp page on button click.The code is as follows
function addRow(type) {
if (type == '') {
alert("Field is empty");
}
else {
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 = "text"; //set the element type
element1.setAttribute('id', 'source'); //set the id attribute
element1.setAttribute('name','source'+rowCount);
element1.setAttribute('value',type);
cell1.appendChild(element1);
}
}
function generate1() {
var table = document.getElementById('my_table');
var rowCount = table.rows.length;
alert(rowCount);
var f = document.form;
f.target="";
f.method="post";
f.action= 'addSource.jsp?rowCount='+rowCount;
}
<form id="form">
<input type="text" id="origin" name="element"/>
<table id="my_table">
<thead><tr>
<th>Source</th>
</tr>
</thead>
<tbody>
</tbody>
</table>
<input type="button" value="Add row" name="add" onClick="addRow(document.forms[0].element.value)" />
<input type="submit" value=" Save" />
You can use location.href Add an id to your form (for example formId) and use something like this:
<script type="text/javascript">
document.getElementById("formId").onclick = function () {
location.href = "addSource.jsp";
};
var x=1
function appendRow(type)
{
var d = document.getElementById('div');
d.innerHTML += "<input type='text' id='source' name='source' value='"+ type +"'><br >";
}
<form action="Source" method="post">
<input type="text" id="origin" name="origin"/>
<div id="div">
<button onclick ="appendRow(document.forms[0].origin.value)" value="Add Row">Add Row</button>
</div>
<input type="submit" name="Save" value=" Save" />
<hr/>
</form>
Controller
#RequestMapping(value = "/Source",params="Save", method = RequestMethod.POST)
public String source(Model model,HttpServletRequest req,HttpServletResponse res,#RequestParam("source") List<String> ola) {
System.out.println("size is:" +ola.size());
for(int i=0; i<ola.size() ;i++) {
String srh = ola.get(i);
System.out.println("srh value is:" +srh);
}
return "redirect:/createPoints";
}

I have a script posted down below, and I want the user to add a new field, when the new field gets added I want a new var to be added.
Live example:
User clicks on the "add new field"
var gets added below var Reason2 called Reason3, Reason4, etc.
"Reason Three: " +Reason3+ gets added below Reason Two on line 51.
I don't have an idea of how to do the above honestly.

In Javascript it's possible to create html elements at runtime using the createElement() function. In your case we need to create quite a lot of individual elements to replicate the structure of the table. Those are <tr> <td> <input>.
The tr element needs to be added to the table, the td containing the text 'Reason #:' as well as the td holding the input element are childs of tr. To add a dynamically created element to the DOM, the appendChild() function is used.
The input element needs some special treatment because it contains an unique id. The two html-made elements you have are 'R1' and 'R2' - so a new one should follow that pattern and start with 3. This is done by setting up a global variable , appending it to the name and increment it afterwards.
Finally we need to add a 'Create new field' button.
Take a look at this example (you have to scroll down to see the button):
var newField = document.getElementById("newField");
var counter = 3;
function createNewField() {
var tr = document.createElement("tr");
var td1 = document.createElement("td");
var td2 = document.createElement("td");
td1.innerHTML = "Reason " + counter + ":";
var inp = document.createElement("input");
inp.type = "text";
inp.size = "75";
inp.name = "R" + counter;
td2.appendChild(inp);
document.getElementById("theTable").appendChild(tr);
tr.appendChild(td1);
tr.appendChild(td2);
counter++;
}
newField.addEventListener("click", createNewField);
function generateCode2() {
var AccoutName = document.forms["TRF"]["accname"].value;
var reasons = "";
for (var a = 1; a < counter; a++) {
reasons += "Reason " + a + ": " + document.forms["TRF"]["R" + a].value + "\n";
}
document.getElementById("box").value =
"[center][img width=500 height=500]https://i.imgur.com/FuxDfcy.png[/img][/center]" +
"[hr]" +
"\n" +
"[b]Dear[/b] " + AccoutName +
"\n" +
"After reading your Application, Imperials staffs have decided to [color=green][b]Accept[/b][/color] you. " +
"\n" + reasons +

I have disabled my submit button to avoid submission when textbox are not filled. I have multiple dynamic textbox where the function works correctly. But upon adding another row of textboxes, the submit button is already enabled. How can I still disable the textboxes when the user decides to add another row? I need the submit button to be enabled whenever all the textboxes are filled, after and before adding another row.
<html>
<head>
<script>
function addRow(){
var table = document.getElementById("bod");
var rowCount = table.rows.length;
var row = table.insertRow(rowCount);
row.insertCell(0).innerHTML = '<input type="text" name="purpose_dy[]" id="purpose" size="20" onkeyup="success()"/>';

Alright i fixed your error , you had some issues where you were enbaling the button and disabling , its always better to itrate and check through the loop rather than going and checking if every element is empty , check the bellow answer and the fiddle . let me know if it works . The edited script part is below , replace it with yours it should work .
<script>
function addRow() {
var table = document.getElementById("bod");
var rowCount = table.rows.length;
var row = table.insertRow(rowCount);
row.insertCell(0).innerHTML = '<input type="text" name="purpose_dy[]" class = "uname" id="purpose" size="20" onkeyup="success()"/>';
row.insertCell(1).innerHTML = '<input type="text" name="wafernum_dy[]" class = "wafernum" id="wafernum" size="20" onkeyup="success()"/>';
row.insertCell(2).innerHTML = '<input type="text" name="cell_dy[]" class = "cell" id="cell" size="20" onkeyup="success()"/>';
row.insertCell(3).innerHTML = '<input type="text" name="qty_dy[]" class = "qty" id="qty" size="20" onkeyup="success()"/>';
row.insertCell(4).innerHTML = '<input type="text" name="remarks_dy[]" class = "remarks" id="remarks" size="20" onkeyup="success()"/>';
row.insertCell(5).innerHTML = '<input type="button" value="Delete" onClick="Javacsript:deleteRow(this)"/>';
}
function success() {
// get all the elements present in form
var unameArray = document.getElementsByClassName("uname");
var ageArray = document.getElementsByClassName("age");
var cellArray = document.getElementsByClassName("cell");
var qtyArray = document.getElementsByClassName("qty");
var wafernumArray = document.getElementsByClassName("wafernum");
var purposeArray = document.getElementsByClassName("purpose");
var remarksArray = document.getElementsByClassName("remarks");
// Check for number of tr
var rowCount = document.getElementById("bod").rows.length;
var bt = document.getElementById('submit_form');
var ele = document.getElementsByTagName('input');
for(var i=0;i<ele.length;i++) {
if (ele[i].type == 'text' && ele[i].value == '') {
bt.disabled = true; // Disable the button.
return false;
}
else {
bt.disabled = false; // Enable the button.
}
}
}
</script>
Modify your conditions a little bit. Now it is working as desired
<html>
<head>
<script>

row.insertCell(1).innerHTML = '<input type="text" name="wafernum_dy[]" class = "wafernum" id="wafernum" size="20" onkeyup="success()"/>';
row.insertCell(2).innerHTML = '<input type="text" name="cell_dy[]" class = "cell" id="cell" size="20" onkeyup="success()"/>';
row.insertCell(3).innerHTML = '<input type="text" name="qty_dy[]" class = "qty" id="qty" size="20" onkeyup="success()"/>';
row.insertCell(4).innerHTML = '<input type="text" name="remarks_dy[]" class = "remarks" id="remarks" size="20" onkeyup="success()"/>';
row.insertCell(5).innerHTML = '<input type="button" value="Delete" onClick="Javacsript:deleteRow(this)"/>';
}
function success() {

I have table with 4 td and user can add row by clicking button and inside each td I have textbox and one of them I have button which open popup window. When user click on this button the popup window will appear with checkboxes after user checked checkboxes the value of them will appear in textbox of parent page that is in same td of button clicked. My problem is when I added new row the value of checked checkboxes only appear in first textbox not in new row, for that I want to assign dynamic id for each added row and post value of checked checkboxes to it. I'm only using Javascript, PHP and html.
This is my parent.php code:

var row = document.createElement("TR");
var td1 = document.createElement("TD");
var strHtml1 = "<INPUT TYPE=\"text\" SIZE=\"255\" MAXLENGTH=\"255\" class=\"textborder\">";
td1.innerHTML=strHtml1 ;

// append data to row
row.appendChild(td1);
row.appendChild(td2);
row.appendChild(td3);
row.appendChild(td4);

Javascript:
//Get a list of input fields to sum

//$('#total_input').html(sum); //If is div, paragraph or another type of container.
});
Is important to make sure the inputs only allow numbers.
HTML
<?php
for($i=1;$1<=5;$i++)
{
?>
<input type="text" id="rate<?php echo $i; ?>" class="rate" name="rate<?php echo $i; ?>">
<?php
}
?><input type="text" name="sum" name"sum">
jQuery
<script type="text/javascript">
$(document).ready(function()
{
for($j=1;$j<=5;$j++)
{
$('#rate'+$j).val('0');
}
});
$sum=0;
$(".rate').keyup(function(){
for($j=1;$j<=5;$j++)
{
$sum=$sum+$('#rate'+$j).val();
alert($sum);
}
$(".sum").html('$sum');
});
</script>
You can iterate on all input elemements using $.each() and get their values.
JavaScript
$(function(){
var inputs = $("input");
inputs.blur(function(){
var total = 0;
$.each(inputs, function(input){
var num = parseInt(inputs[input].value);
total += (!isNaN(num))? num : 0;
});
$("#total").html(total)
HTML
<input type="text">
<input type="text">
<input type="text">
<input type="text">
<input type="text">
<p>
Total : <span id="total"></span>
