I have question about calculation multiply form fields on event change.
Calaculation for new form fields form modila works fine. I have on each form field event if img-X is clicked the form field must be erased, and all fields must be calculated again for new result after that field is deleted.
The problem is in my <tr></tr> tags insade table, i have text with class pdv, and that field must be calculated with sum of two values kolicina * cijena, I mean calculation of three fields give result for output.
Better explanation I will provide with code below, and will explain in details.
html
<tbody>
<tr class="opa">
<td>234</td>
<td>Penkala za ured</td>
<td>
<input type="text" class="form-control" placeholder=" Napomena"/>
</td>
<td>Komad</td>
<td>
<input type="text" class="form-control kolicina" placeholder=" Količina" />
</td>
<td>
<input type="text" class="form-control cijena" placeholder=" Cjena"/>
</td>
<td>
<input type="text" class="form-control popust" placeholder=" Popust"/>
</td>
<td class="pdv">13%</td>
<td>10.00</td>
<td>
<img class="img-responsive remove_element" src="../images/forms/icon_delete.png"/>
</td>
</tr>
<tr class="opa">
<td>1</td>
<td>Čokolada</td>
<td>
<input type="text" class="form-control" placeholder=" Napomena"/>
</td>
<td>Komad</td>
<td>
<input type="text" class="form-control kolicina" placeholder=" Količina"/>
</td>
<td>
<input type="text" class="form-control cijena" placeholder=" Cjena"/>
</td>
<td>
<input type="text" class="form-control popust" placeholder=" Popust"/>
</td>
<td class="pdv">25%</td>
<td>5.30</td>
<td>
<img class="img-responsive remove_element" src="../images/forms/icon_delete.png"/>
</td>
</tr>
<tr class="opa">
<td>52</td>
<td>Pranje auta</td>
<td>
<input type="text" class="form-control" placeholder=" Napomena"/>
</td>
<td>Komad</td>
<td>
<input type="text" class="form-control kolicina" placeholder=" Količina"/>
</td>
<td>
<input type="text" class="form-control cijena" placeholder=" Cjena"/>
</td>
<td>
<input type="text" class="form-control popust" placeholder=" Popust"/>
</td>
<td class="pdv">25%</td>
<td>6.40</td>
<td>
<img class="img-responsive remove_element" src="../forms/icon_delete.png"/>

This is my table with results, you can see class kolicina - cijena - popust - pdv, that is all for calculation of form fields. The question is how to take current text from class pdv and calculate with kolicina - cijena - popust, then after calculation append to some element in html.
In jQuery I have acomplished calculation of fields kolicina - cijena - popust, and append them to HTML elemnet. The problem is when pdv text value is 25 or 13 or 5 calculation must go into separated html element.
html
<span><a class="sum">0 </a></span>
<span><a class="popust_count">0 </a></span>
<span><a class="popust_all">0 </a></span>
<span><a class="sum">0 </a></span>
<span>PDV 25%: <a class ="pdv_25">0 </a> | PDV 13%: <a class="pdv_13">0 </a> | PDV 5%: <a class="pdv_5">0 </a></span>
And my jQuery code looks like: This code works.
$(".prod_go input").keyup(multInputs);
$(".remove_element").click(function() {
$(this).parent().parent().remove();
multInputs();
});
function multInputs() {
var mult = 0;
var sa_popust_uk = 0;
var pdv_25 = 0;
var pdv_13 = 0;
var pdv_5 = 0;
// for each row:
$("tr.opa").each(function () {
// get the values from this row:
var $kolicina = $('.kolicina', this).val();
var $cijena = $('.cijena', this).val();
var $popust = $('.popust', this).val();
var $total = ($kolicina * 1) * ($cijena * 1);
var $total_popus = ($kolicina * 1) * ($cijena * 1) * (($popust * 1)/100);
/*Porez*/
var value1 =Number($(this).closest('tr.opa').find('td[class=pdv]').text().replace(/[%]/g, ""));
if (value1 === 25){
var kaos = ($kolicina * 1) * ($cijena * 1) * (0.25 * 1);
pdv_25 +=kaos;
}
if (value1 === 13){
var kaos = ($kolicina * 1) * ($cijena * 1) * (0.13 * 1);
pdv_13 +=kaos;
}
if (value1 === 5){
var kaos = ($kolicina * 1) * ($cijena * 1) * (0.05 * 1);
pdv_5 +=kaos;
}
// set total for the row
//$('.sum').text($total);
mult += $total;
sa_popust_uk += $total_popus;
});
$(".popust_all").text(mult-sa_popust_uk.toFixed(2)+' kn');
$('.sum').text(mult.toFixed(2)+' kn');
$('.popust_count').text(sa_popust_uk.toFixed(2)+' kn');
/*Append PDV to page*/
$('.pdv_25').text(pdv_25.toFixed(2)+' kn');
$('.pdv_13').text(pdv_13.toFixed(2)+' kn');
$('.pdv_5').text(pdv_5.toFixed(2)+' kn');
$('.sum_od_all').text((mult+pdv_25+pdv_13+pdv_5).toFixed(2)+' kn');
console.log('PDV 25:'+ pdv_25+' PDV 13:'+ pdv_13+' PDV 5:'+ pdv_5);
//$(".sum_od_all").text(mult);
}
});
If you can have a look and give me some advice on this form calculation.
