Demo:
I'm really sorry if my question is very novice as I'm very new to HTML & JS. I'm trying add two table data(Default value and Extra) and print the numeric output in the third column(Output)
Also I wanted to know if I hit the submit button can the updated page(with the third column updated) will populate on the same page
Hope I have conveyed it correctly, thanks.
<form name="CheckOn" >
<table BORDER="1">
<tr class="heading">
<td>Items</td>
<td>Default value</td>
<td>Extra(if any)</td>
<td>Output</td>
</tr>
<tr>
<tr>
<td>Apple</td>
<td>
<input type="text" value="26" size=15 name="apple">
</td>
<td>
<input type="text" value="0" size=15 name="apple">
</td>
<td>
<input type="text" size=15 name="apple">
</td>
</tr>
<tr>
<td>Mango</td>
<td><input type="text" size=15 value="26" name="mango"></td>
<td>
<input type="text" value="0" size=15 name="mango">
</td>
<td>
<input type="text" size=15 name="mango">
</td>
</tr>
</table>
<p><input type="submit" value="submit" name="subs"></p>

I think simply you have to iterate each tr
and do the sum of each input
inside the td
(skipping the result td
only) .
1. Iterate for each tr
inside table
.
2. Do the sum of each input
inside the td
of each tr
.
3. If td
is having result td
index then set the sum value.
Here is working snippet:
Note: I have assigned id
to table.
document.getElementById("subs").addEventListener("click", function(e){
e.preventDefault(); //Just prevent to form submit for demo.
var resultTD=3;
$('#tblID tr').each(function() {
var sum=0;
$.each(this.cells, function(index){
if(index==resultTD){
$(this).find("input").val(sum);
}else{
$(this).find("input").each(function(index) {
sum=sum+parseInt(this.value);
});
}
});
});
});
tr.heading {
display: table-row;
font-size:18px;
font-family:cursive;
background-color:lightgreen;
cursor:pointer;
border-collapse:collapse;
font-weight:bold;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form name="CheckOn" >
<table id="tblID" BORDER="1">
<tr class="heading">
<td>Items</td>
<td>Default value</td>
<td>Extra(if any)</td>
<td>Output</td>
</tr>
<tr>
<td>Apple</td>
<td>
<input type="text" value="26" size=15 name="apple">
</td>
<td>
<input type="text" value="0" size=15 name="apple">
</td>
<td>
<input type="text" size=15 name="apple">
</td>
</tr>
<tr>
<td>Mango</td>
<td><input type="text" size=15 value="26" name="SDK"></td>
<td>
<input type="text" value="0" size=15 name="SDK">
</td>
<td>
<input type="text" size=15 name="SDK">
</td>
</tr>
<tr>
<td>Banana</td>
<td>
<input type="text" value="26" size=15 name="Banana">
</td>
<td>
<input type="text" value="27" size=15 name="Banana">
</td>
<td>
<input type="text" size=15 name="Banana">
</td>
</tr>
<tr>
</table>
<p><input type="submit" value="submit" id="subs" name="subs"></p>
