Example :
Let’s head to the step by step coding part.
- Add HTML Markup
- jQuery code:
- Bind textbox change event
- Calculate sum of all textboxes
# Add HTML: Textbox and HTML Table added.
Here first we add a HTML table which contains two column 1st as name and 2nd as price. In the price column we added Textboxes and also, assign a specific class name to it .i.e class=”txtCal” in our case. Class name txtCal used as jquery selector to get all textboxes value for calculating purpose. Here’s how our HTML looks like
//*
<table id="myTable">
<tr> <th width="100">Name </th>
<th>Price</th>
</tr>
<tr>
<td><span>Pen :</span></td>
<td><input type="text" class='txtCal' /></td>
</tr>
<tr>
<td><span>Pencil :</span></td>
<td><input type="text" class='txtCal' /></td>
</tr>
<tr>
<td><span>Eraser :</span></td>
<td><input type="text" class='txtCal' /></td>
</tr>
<tr>
<td><span>Sharpner :</span></td>
<td><input type="text" class='txtCal' /></td>
</tr>
<tr>
<td><span>Book :</span></td>
<td><input type="text" class='txtCal' /></td>
</tr>
<tr>
<td><span><b>TOTAL :</b></span></td>
<td><b><span id="total_sum_value"></span></b></td>
</tr>
</table>
//*
# jQuery Code: Bind Textbox Change Event
In jquery for click event we use .click(), for text change event we can achieve it with multiple event .i.e using .blur() / .focus() / keyUp() / keyDown() etc . But the best way is to use like .input. So now we write code on how to bind jquery event on the dynamically added element, i.e., binding textbox change event. This is how our code looks like.
//*
$(document).ready(function () {
$("#myTable").on('input', '.txtCal', function () {
// code logic here
var getValue=$(this).val();
console.log(getValue);
});
});
//*
# jQuery code: Calculate the sum of all textboxes.
Now it’s time to the main part of this article where we are going to calculate the sum of all the textboxes and sets its final amount at table footer. First, we make a loop over the table row using .each() to get the value of each textbox. Then we check whether the entered values are numbers only using isNumeric(). Is the entered value is numeric then only will add it our variable (calculated_total_sum). Now we set the calculated_total_sum value to Table footer which gives us the Total sum of all the textboxes.
//*
$(document).ready(function () {
$("#myTable").on('input', '.txtCal', function () {
var calculated_total_sum = 0;
$("#myTable .txtCal").each(function () {
var get_textbox_value = $(this).val();
if ($.isNumeric(get_textbox_value)) {
calculated_total_sum += parseFloat(get_textbox_value);
}
});
$("#total_sum_value").html(calculated_total_sum);
});
});
//*
