sending checked box values to php script to process via jquery - php

Question

I have a table with four columns with a checkbox at the end of each row. I would like to know if there is a way of writing a jquery function that will select all the values of each row when the check box has been ticked and the submit button has been clicked.. and then pass the values to .php file to process/display. The reason i want to use the .php file is because i want to run a query to show all registered users on my system and then send the checked rows (id and name) to those users.
Sounds very complicated but i really need some help. thanks in advance.
here is the html code:
<div class="valuesOfObs">
<table>
<thead><tr><th>Valuation Name</th><th>Valuation Goal</th><th>Valuation Description</th><th>Options</th><th>Invite</th></tr></thead>
<tbody>
<?php
$sql = 'SELECT * FROM valuation';
$results = $db->query($sql);
$rows = $results->fetchAll();
foreach ($rows as $row) {
echo '<tr id="'.$row['ValuationID'].'">';
echo '<td class="crsDesc">'.$row['ValuationName'].'</td>
<td >'.$row['ValuationGoal'].'</td>
<td >'.$row['ValuationDescription'].'</td>
<td ><a href =values.php?action=invite&id=aValue> xValue </a></td>
<td > <input type="checkbox" name="selectValue">
</td>';
echo '</tr>';
}?>
</tbody>
</table>
</div>
<input type="button" name="addrow" id="addrow" value="Add row">
<input type="button" name="inviteObs" id="inviteObs" value="Invite Obstacle";>
Here is what I have written for the jquery so far.. I am trying to spilt the values so i can choose specifically which ones to process and then later on user the .join() method. Please help out if on the wrong track
$("input[type=checkbox], input[type=button]").on("click", function () {
$( ":checked" ).map(function() {
return $(this).closest("tr").text();
}).split("</td><td>");
var compName = $("#id").val();
$.ajax({
url : "inviteObstacles.php",
type : "POST",
data : {"compID" : compName},
success : function (n){
//do something
}
})
});

Use .map() function to pass each element in the current matched set through a function, which will produce new jQuery object containing the return values.
Here is a code:
$("input[type=checkbox]").on("click", function () {
$( ":checked" ).map(function() { return $(this).closest("tr").text();
}).get().join(); //Use join to split the fetched row using separator "," on server-side
});
