I'm building a form where I need multiple optional inputs, what I have is basically this:
Every time a user presses the plus button a new row of form inputs should be added to the form, how can I do this in jQuery? Also, is it possible to automatically add a new row when all rows (or just the last row, if it's easier / faster) are filled? That way the user wouldn't need to press the plus button.
I'm sorry for asking maybe such a basic question but I'm still very green with jQuery, I could do this with PHP but I'm sure Javascript / jQuery plays a more appropriate role here.
Thanks in advance!
<!DOCTYPE html> <head> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.0/jquery.min.js"></script> <script type="text/javascript"> $form = $('#personas'); $rows = $form.find('.person'); $('a#add').click(function() { $rows.find(':first').clone().insertAfter($rows.find(':last')); $justInserted = $rows.find(':last'); $justInserted.hide(); $justInserted.find('input').val(''); // it may copy values from first one $justInserted.slideDown(500); }); </script> </head> <body> <form id="personas" name="personas" method="post" action=""> <table width="300" border="1" cellspacing="0" cellpadding="2"> <tr> <td>Name</td> <td>More?</td> </tr> <tr class="person"> <td><input type="text" name="name[]" id="name[]" /></td> <td><a href="#" id="add">+</a></td> </tr> </table> </form> </body> </html>
This will get you close, the add button has been removed out of the table so you might want to consider this...
<script type="text/javascript"> $(document).ready(function() { $("#add").click(function() { $('#mytable tbody>tr:last').clone(true).insertAfter('#mytable tbody>tr:last'); return false; }); }); </script>
HTML markup looks like this
<a id="add">+</a></td> <table id="mytable" width="300" border="1" cellspacing="0" cellpadding="2"> <tbody> <tr> <td>Name</td> </tr> <tr class="person"> <td><input type="text" name="name" id="name" /></td> </tr> </tbody> </table>
EDIT To empty a value of a textbox after insert..
$('#mytable tbody>tr:last').clone(true).insertAfter('#mytable tbody>tr:last'); $('#mytable tbody>tr:last #name').val(''); return false;
EDIT2 Couldn't help myself, to reset all dropdown lists in the inserted TR you can do this
$("#mytable tbody>tr:last").each(function() {this.reset();});
I will leave the rest to you!
As an addition to answers above: you probably might need to change ids in names/ids of input elements (pls note, you should not have digits in fields name):
<input name="someStuff.entry[2].fieldOne" id="someStuff_fdf_fieldOne_2" ..>
I have done this having some global variable by default set to 0:
var globalNewIndex = 0;
and in the add function after you've cloned and resetted the values in the new row:
var newIndex = globalNewIndex+1; var changeIds = function(i, val) { return val.replace(globalNewIndex,newIndex); } $('#mytable tbody>tr:last input').attr('name', changeIds ).attr('id', changeIds ); globalNewIndex++;
