i need help. jquery code not work / not recognized browser. i'm trying insert new row when user clicks 'add new' button.

i pasted on jsfiddle: ** http://jsfiddle.net/rjjrt/ **

my jquery code:

$(document).ready(function(){   // add button click event   $("#addnew").click(function(){     addnewrow();   }); });  // add new row when add task button clicked function addnewrow(){  var numrows = $('#tasktable tr').length;  $('#tasktable').append('   <tr>    <td><input type="text" id="title-'+numrows+'" placeholder="your task name"/></td>    <td><input type="text" id="description-'+numrows+'" placeholder="task description"/></td>    <td><input type="button" class="deletebutton" id="delete-'+numrows+'" title="delete task" value="delete" /></td>   </tr>  '); }

i tried

$('#tasktable tr:last').after(...

but didn't work either.

my html code:

<div class="around-table"> <table id="tasktable">   <tr>     <th>task</th>     <th>description</th>     <th></th>   </tr>   <tr>     <td><input type="text" id="title-1" placeholder="your task name"/></td>     <td><input type="text" id="description-1" placeholder="task description"/></td>     <td><input type="button" class="deletebutton" id="delete-1" title="delete task" value="delete" /></td>   </tr>   <tr>     <td><input type="text" id="title-2" placeholder="your task name"/></td>     <td><input type="text" id="description-2" placeholder="task description"/></td>     <td><input type="button" class="deletebutton" id="delete-2" title="delete task" value="delete" /></td>   </tr> </table>  <input type="button" id="addnew" value="add task" />  </div>

thanks help.

---- after fixing ---- adding new row function works but, deleting row function not work newly added rows...

// function runs on page load $(document).ready(function(){   // add button click event   $("#addnew").click(function(){     addnewrow();   });   // delete button click event   $('.deletebutton').click(function(){     deleterow($(this));   }); });   // add new row when add task button clicked function addnewrow(){   var numrows = $('#tasktable tr').length;   $('#tasktable tr:last').after('\     <tr>\       <td><input type="text" id="title-'+numrows+'" placeholder="your task name"/></td>\       <td><input type="text" id="description-'+numrows+'" placeholder="task description"/></td>\       <td><input type="button" class="deletebutton" id="delete-'+numrows+'" title="delete task" value="delete" /></td>\    </tr>\   '); }  // delete grandparent of delete button // entire row of table (tr > td > a) function deleterow(button){  button.parent().parent().remove(); }

you can't have multiline strings in javascript without little trickery, code fail on line

$('#tasktable').append('

and nothing execute. can, however, have multiline strings if escape newline character backslash:

$('#tasktable').append(' \

just make sure backslash last character on line.

in case, though, build html in jquery instead:

$('#tasktable').append(     $('<tr>').append($('<input>')         .attr('type','text')         .attr('id','title-'+numrows)         .attr('placeholder','your task name')     ).append($('<input>')         .attr('type','text')         .attr('id','description-'+numrows)         .attr('placeholder','task description')     ).append($('<input>')         .attr('type','button')         .attr('id', 'delete-'+numrows)         .attr('title', 'delete task')         .val('delete')         .addclass('deletebutton)     )) );

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2
