I am trying to perform the following functionality using JS. I have achieved the total number of participant's sum but it is not working when i add rows dynamically. It only take effect when i change the first row only.
No of participants * Subsidy Per Participant = Total Training Value
Total Training Value Column Sum in Total Assignment Value
Furthermore, i have no idea how to get Total Training Value of each row and sum of total training values. Can you help me out in this regard so i can finish what i started.
//Dynamic Add Delete Rows
$(document).ready(function() {
var i = 1;
$("#add_row").click(function() {
$('#addr' + i).html("<td>" + (i + 1) + "</td><td><select class='form-control' required name='topic[" + i + "]'><option selected disabled value=''>Select Topic</option><option value='1'>Topic 1</option></select></td><td><input name='alloc_trainig[" + i + "]' type='text' placeholder='Allocated Trainings' class='form-control input-md'></td><td><input name='add_traing[" + i + "]' type='text' placeholder='Additional Trainings (if Any)' class='form-control'></td><td><input name='no_patycpnt[" + i + "]' id='no_patycpnt' type='text' placeholder='No. of Participants' class='Participants form-control input-md'></td><td><input name='prosd_days[" + i + "]' type='text' placeholder='Proposed Days' class='form-control input-md'></td><td><input name='subsify_per_patrcpnt[" + i + "]' type='text' placeholder='Subsidy Per Participant' class='Subsidy form-control input-md'></td><td><input type='text' name='total_value[" + i + "]' id='total_value' placeholder='Total Value' readonly class='form-control'/></td>");

i++;
});
$("#delete_row").click(function() {
if (i > 1) {
$("#addr" + (i - 1)).html('');
i--;
}
});
});
//Calculation Code
$(".Participants").change(function() {
var sum = 0;
$('.Participants').each(function(i, obj) {
if ($.isNumeric(this.value)) {
sum += parseFloat(this.value);
}
})

Try remove numeric check and realize the calculations without any restrictions, do a minimal test, likely it will work.
i am using jquery plugin bootstrap select
my code
$('.selectpicker').on('hidden.bs.select', function (e) {
$('.selectpicker').selectpicker({
style: 'btn-info',
size: 4,
liveSearch: true
});
});
refreshing in code
$(document).ready(function(){
var i=1;
$("#add_row").click(function(){
$('#addr'+i).html("<td>"+ (i+1) +"</td><td><select class='selectpicker'
data-'live-search=true' name='name"+i+"'><option>Mustard</option>
<option>Ketchup</option><option>Relish</option></select> </td><td><input

class='form-control input-md'></td>");
$('#tab_logic').append('<tr id="addr'+(i+1)+'"></tr>');
$('.selectpicker').selectpicker('refresh');
i++;
});
but after refreshing i am not getting

You have
data-'live-search=true'
it should be
data-live-search='true'
$('.selectpicker').on('hidden.bs.select', function(e) {
$('.selectpicker').selectpicker({
style: 'btn-info',
size: 4,
liveSearch: true
});

$(document).ready(function() {

I want to add a new bootstrap row with one click, I tried this, but I only get a new row with number, not the copy of a complete row:
<table class="table table-bordered table-hover" id="tab_logic">

<tr>
<th class="text-center">

<th class="text-center">

</table>
<a id="add_row" class="btn btn-default pull-left">Add Row</a>
<a id='delete_row' class="pull-right btn btn-default">Delete Row</a>
Script:
$(document).ready(function(){
var i=1;
$("#add_row").click(function(){
$('#addr'+i).html("<td>"+ (i+1) +"</td>")
$('#tab_logic').append('<tr id="addr'+(i+1)+'"></tr>');
i++;
});
$("#delete_row").click(function(){
if(i>1){
$("#addr"+(i-1)).html('');
i--;
}
});
});
Why only add new row with number of row instead of row with two dropdowns and one field?
Thanks in advance!
Simply because that what you have passed in "<td>"+ (i+1) +"</td>".
You could add the content of default row #addr0 in every row you add :
$('#addr'+i).html($('#addr0').html());
Hope this helps.
$(document).ready(function(){
var i=1;
$("#add_row").click(function(){
$('#addr'+i).html($('#addr0').html());

You have to get previous HTML code into new row.
<script>
$(document).ready(function(){
var i=1;
$("#add_row").click(function(){
lastobj = "#addr"+""+(i-1);
content = $(lastobj).html();
$('#addr'+i).html(content);
$('#tab_logic').append('<tr id="addr'+(i+1)+'"></tr>');
i++;
});
$("#delete_row").click(function(){
if(i>1){
$("#addr"+(i-1)).html('');
i--;
}
});
});
</script>
Also use ID to get their value or using an arrays.
I have this piece of code that should do the following:
After typing into each input field and pressing the "Add row" button a new row should be added to the end of the table. Pressing the "Delete row" button should remove the last row created.
At this point, when I press any of the buttons, it won't do anything.
As a mention, when I am verifying Chromes' Console for any JS errors I get this:
Uncaught ReferenceError: $ is not defined
This is the HTML:
<body style="background-color:lavender">

</div>
<a id="add_row" class="btn btn-default pull-left">Add Row</a><a id='delete_row' class="pull-right btn btn-default">Delete Row</a>

And this is the JS:
$(document).ready(function(){
var i=1;
$("#add_row").click(function(){
$('#addr'+i).html("<td>"+ (i+1) +"</td><td><input name='user"+i+"' type='text' placeholder='User' class='form-control input-md' /></td><td><input name='pass"+i+"' type='text' placeholder='Password' class='form-control input-md'></td><td><input name='ip"+i+"' type='text' placeholder='IP' class='form-control input-md'></td><td><input name='country"+i+"' type='text' placeholder='Country' class='form-control input-md'></td><td><input name='ipDisp"+i+"' type='text' placeholder='IP details' class='form-control input-md'></td>");
$('#tab_logic').append('<tr id="addr'+(i+1)+'"></tr>');
i++;
});
$("#delete_row").click(function(){
if(i>1){
$("#addr"+(i-1)).html('');
i--;
}
});
});
Any ideas on what should I change in my JS ?
Thanks
Remember jquery library must be placed first than bootstrap, maybe that would be your problem, your code is fine, here is the working fiddle using jquery 1.11.0
<script src="jquery.min.js">
<script src="bootstrap.min.js">
The fiddle [1]: http://jsfiddle.net/gLrhnqo2/
You need add the Jquery script. If you select the latest version works good.
I want to create a dynamic table. This code was working fine for me until I had Text box instead of this combo box in "Recruitment stage " column
I have used help of this code snippet http://bootsnipp.com/snippets/featured/dynamic-table-row-creation-and-deletion
So my problem is I can't add rows after changing above mentioned code snippet into below code.
So please some one tell me why this isn't working?
