Dynamically inserted textbox values to be stored in a variable - codeigniter

Question

<tr style="background: #D0CDCD;">
<td colspan='2'>
<input type="text" name="mytext1[]">
</td>
<td></td>
<td colspan='2' style="text-align:right;">
<input type="text" name="mytext2[]" id="txt1" onkeyup="sum();">
</td>
</tr>
This is my html code to add dynamic textboxes.
JS Script is follows
<script type="text/javascript">
$(document).ready(function() {
var max_fields= 3;
var x = 1;
$('a').click(function() {
if(x < max_fields){
x++;
$('#myTable #row').append('<tr class="child"><td class="child" colspan="2"><input type="text" name="mytext1[]"></td><td></td><td colspan="2" style="text-align:right;"><input type="text" name="mytext2[]"></td></tr>');
}
});
});
</script>
My problem is that I need to store the dynamically added textbox values to a variable so that I can perform some mathematical operations in that. I don't know how to achieve this. Please help me.

Answer 1

I got the result. I make use of javascript and jQuery
<tr style="background: #D0CDCD;">
<td colspan='2'><input type="text" name="mytext1[]"></td>
<td></td>
<td colspan='2' style="text-align:right;">
<input type="text" class="value_field" name="mytext2[]" >
</td>
</tr>
Function to append
<script type="text/javascript">
$(document).ready(function() {
$('a').click(function() {
$('#myTable #row').append('<tr class="child"><td class="child" colspan="2"><input type="text" name="mytext1[]"></td><td></td><td colspan="2" style="text-align:right;"><input type="text" name="mytext2[]" class="value_field"></td></tr>');
$("input.value_field").blur(function(){
check_value();
});
});
});
$("input.value_field").blur(function(){
check_value();
});
