how to get value from java script function to perl -


i want value of check box selected , pass query deleting value database. java script code 

function deleterows(){  istable = document.getelementbyid('datatbl'); nboxes = document.getelementsbyname('delbox'); (i=nboxes.length-1; i>=0; i--) { if (nboxes[i].checked === true) { var =nboxes[i].value;   alert("do want delete row?"+a); istable.deleterow(i+1); } } }

i need var a value in perl can pass delete query , delete selected row.

html code 

<table id='datatbl' border='1' > <tr> <td><input type=checkbox name='delbox' value=@data></td>  <td bgcolor=#0099ff>$pid</td> <td bgcolor=#99ccff>$project_name</td> <td bgcolor=#3399ff> $variant_no</td> <td bgcolor=#99ccff> $variant_name</td> <td bgcolor=#3399ff>$vehicle_class</td> <td bgcolor=#99ccff> $vc_no</td> </table> <input type=button value="delete rows" onclick="deleterows()" id="delbtn">

perl query 

my $sth = $dbh->prepare("delete form table name col1,col2,col3 id='$a'");  $sth->execute() or die "$!";

you have post request (or delete precise) towards server perl script runs.

e.g.

after variable set (let's using jquery):

$.ajax({   type: "post",   url: url, // script lives   data: {'a' : a},   success: function(data) {       console.log(data);   }   datatype: 'json' });

in script 'a' variable post request.
