How to dynamically add row in Bootstrap
Question
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 class="container">
<div class="row clearfix">
<div class="col-md-12 column">
<table class="table table-bordered table-hover" id="tab_logic">
<thead>
<tr >
<th class="text-center">
#
</th>
<th class="text-center">
User
</th>
<th class="text-center">
Password
</th>
<th class="text-center">
IP
</th>
<th class="text-center">
Country
</th>
<th class="text-center">
IP disponibility
</th>
</tr>
</thead>
<tbody>
<tr id='addr0'>
<td>
1
</td>
<td>
<input type="text" name='user0' placeholder='User' class="form-control"/>
</td>
<td>
<input type="text" name='pass0' placeholder='Password' class="form-control"/>
</td>
<td>
<input type="text" name='ip0' placeholder='IP' class="form-control"/>
</td>
<td>
<input type="text" name='country0' placeholder='Country' class="form-control"/>
</td>
<td>
<input type="text" name='ipDisp0' placeholder='IP Details' class="form-control"/>
</td>
</tr>
<tr id='addr1'></tr>
</tbody>
</table>
</div>
</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>
</div>
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">

You need add the Jquery script. If you select the latest version works good.
