Made button form and in js file its not triggering

I completed this form inside bootstrap table earlier it was working but after I added just option. Its not even triggering JS file code with only alert also while other buttons of different forms are triggering all these are in same JS file.
Here is form code : (Ps since using PHP called this file in index.php file this is other php file)
<div id="sixth-part" class=tabcontent>
<h2 class="main-headings">Painting</h2>
<form action="Controller/painting.php" method="POST" id="painting-form">
<table data-toggle="table">
<thead>
<tr>

<td><p id="eid6"><?php echo $login_session; ?></p></td>
</tr>
</tbody>
</table>
</form>
</div>
<div id='response6'></div>
Here is JS code :
$(document).ready(function() {
$('#painting-form').submit(function(event) {
alert("hi");
var formData = {
pumpserialno: $("#pumpserialno7").text(),
antirushcoating: $("#antirushcoating").val(),
eid:$("#eid6").text()
}
$.ajax({
type : 'POST', // define the type of HTTP verb we want to use (POST for our form)
url : 'Controller/painting.php', // the url where we want to POST
data : formData, // our data object
dataType : 'text', // what type of data do we expect back from the server
encode : true,
success: function( data ) {
$("#response6").html(data);
},
error: function(xhr, status, error) {
// check status && error
},
})
// using the done promise callback
.done(function(data) {
// log data to the console so we can see
console.log(data);
$('#myModal').modal('show');
});
event.preventDefault();
// alert($("#visual-inspection").val());
});
});
Here is Index file code : (Called this file in this way)
include("Parts/Insert/part6.php");

Jquery Filter table rows by multiple checkboxes

I am trying to get a filter working for a table. What I would like is checkboxes to filter (hide) rows based on whether they're checked or not and if the value is present in the table cell. I have it somewhat working, but it will only sort one of the checkboxes. Also, if there are multiple values in the table cell being filtered, that row is hidden. Thoughts? Thank you in advance for any help. I'm really struggling with this for some reason!
Here is the code I have been using:
$("input:checkbox").click(function () {
var showAll = true;
$('tr').not('.first').hide();
$('input[type=checkbox]').each(function () {
if ($(this)[0].checked) {
showAll = false;
var status = $(this).attr('rel');
var value = $(this).val();
$('td.' + 'status' + '[rel="' + value + '"]').parent('tr').show();
}
});
if(showAll){
$('tr').show();
}
});
The markup is as follows (please excuse some messiness, its Wordpress)
<div class="grants-filter">
<h3 class="filter-title">Filter Scholarships</h3><br/>
<h3>Year of Study:</h3>
<input type="checkbox" name="chx" rel="status" value="Freshman">Freshman
<input type="checkbox" name="chx" rel="status" value="Sophmore">Sophmore
<input type="checkbox" name="chx" rel="status" value="Junior">Junior
<input type="checkbox" name="chx" rel="status" value="Senior">Senior

<input type="checkbox" rel="duration" value="Summer">Summer
<input type="checkbox" rel="duration" value="Semester">Semester
<input type="checkbox" rel="duration" value="Full Year or More">Full Year or More
</div>
<div class="grants-listing">

<thead>
<tr class="first">
<th>Title</th>
<th>Description</th>
<th>Field</th>

<th>URL</th>
</tr>
</thead>
<tbody>
<?php
$grargs = array ( 'post_type' => 'scholarship');
$grant_query = new WP_Query( $grargs );
while ( $grant_query -> have_posts() ):
$grant_query -> the_post(); ?>
<tr class="grant-detail">
<td>
<?php the_title(); ?>
</td>
<td><?php echo wp_trim_words(get_the_content(), 25 ); ?></td>
<td class="fields" rel="<?php echo get_field('fields'); ?>"><?php echo the_field('fields'); ?></td>
<td class="duration" rel="<?php echo the_field('desired_duration'); ?>"><?php echo the_field('desired_duration'); ?></td>
<td class="status" rel="<?php echo the_field('year-of-study'); ?>"><?php echo the_field('year-of-study'); ?></td>
<td class="other" rel="<?php echo the_field('other'); ?>"><?php echo the_field('other'); ?></td>
<td class="procedure" rel="<?php echo the_field('procedure'); ?>"><?php echo the_field('procedure'); ?></td>
<td class="url"><?php echo get_field('url'); ?></td>
</tr>
<?php endwhile;
wp_reset_postdata(); //reset the first query
?>
</tbody>
</table>

As I think you just are calling the first checkbox [0]
if ($(this)[0].checked) {
call all by inserting someting like
$('input[type=checkbox]').each(function () {
if (this.checked) {
console.log($(this).val());
}
});

Your code works fine, here is a simplified version
$("input:checkbox").click(function() {
var showAll = true;
$('tr').not('.first').hide();
$('input:checkbox:checked').each(function() {
showAll = false;
var status = $(this).attr('rel');
var value = $(this).val();
$('td.' + 'status' + '[rel="' + value + '"]').parent('tr').show();
});
if (showAll) {
$('tr').show();
}
});

What is the best suitable JavaScript Which disables the delete a.button until have clicked the correct corresponding check-box
If button is disabled I would like to be able to use bootstraps disabled="disabled"
<div class="table-responsive" id="user">
<table class="table table-bordered table-hover">

</td>

<?php } ?>
<?php } ?>
</tbody>

First, all the delete buttons should be disabled when you first load the HTML. You can add the disabled='disabled' attribute to each delete button in your PHP code.
Then in JavaScript you look for a change event on the checkbox:
$("input[type='checkbox']").change(function() {
var thisRow = $(this).parents("tr");
if(this.checked) {
thisRow.find("a.btn-danger").attr("disabled", false);
} else {
thisRow.find("a.btn-danger").attr("disabled", "disabled");
}
});
