• Deleting multiple rows from a table with empty validation, employing either PHP on the server-side or jQuery on the client-side.

Simple jQuery Script to Delete Single/Multiple Selected Rows

Step 1: We have included the jQuery and bootstrap files.

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/js/bootstrap.min.js"></script>

Step 2: Let’s define HTML table rows.

<div class="container" style="padding:0 250px;">
<h1>A Simple Example Delete Multile Rows Using PHP and jQuery</h1>
<div class="row well">
 <a type="button" class="btn btn-primary pull-right delete_all">Delete Selected</a>
</div>
<table id="employee_grid" class="table table-condensed table-hover table-striped bootgrid-table" width="60%" cellspacing="0">
   <thead>
      <tr>
         <th><input type="checkbox" id="master"></th>
         <th>Name</th>
         <th>Salary</th>
         <th>Age</th>
   <th class="pull-right">Delete</th>
      </tr>
   </thead>
   <tbody>
      <tr data-row-id="1">
         <td><input type="checkbox" class="sub_chk" data-id="1"></td>
         <td>Tiger Nixon</td>
         <td>320800</td>
         <td>61</td>
   <td><a class="remove-row pull-right" targetDiv="" data-id="1" href="javascript: void(0)"><i class="glyphicon glyphicon-trash"></i></a></td>
      </tr>
      <tr data-row-id="5">
         <td><input type="checkbox" class="sub_chk" data-id="5"></td>
         <td>Airi Satou</td>
         <td>162700</td>
         <td>33</td>
   <td><a class="remove-row pull-right" targetDiv="" data-id="5" href="javascript: void(0)"><i class="glyphicon glyphicon-trash"></i></a></td>
      </tr>
      <tr data-row-id="6">
         <td><input type="checkbox" class="sub_chk" data-id="6"></td>
         <td>Brielle Williamson</td>
         <td>372000</td>
         <td>61</td>
   <td><a class="remove-row pull-right" targetDiv="" data-id="6" href="javascript: void(0)"><i class="glyphicon glyphicon-trash"></i></a></td>
      </tr>
      <tr data-row-id="7">
         <td><input type="checkbox" class="sub_chk" data-id="7"></td>
         <td>Herrod Chandler</td>
         <td>137500</td>
         <td>59</td>
   <td><a class="remove-row pull-right" targetDiv="" data-id="7" href="javascript: void(0)"><i class="glyphicon glyphicon-trash"></i></a></td>
      </tr>
   </tbody>
</table>
</div>

Step 3: This function is used for selecting all table records. You can use this function to Check all & Uncheck all elements.

jQuery('#master').on('click', function(e) {
 if($(this).is(':checked',true))  
 {
  $(".sub_chk").prop('checked', true);  
 }  
 else  
 {  
  $(".sub_chk").prop('checked',false);  
 }  
});

Step 4: Define the jQuery function to delete all records using Ajax request(Server-Side) or jQuery(Client-Side).

jQuery('.delete_all').on('click', function(e) { 
var allVals = [];  
  $(".sub_chk:checked").each(function() {  
   allVals.push($(this).attr('data-id'));
  });  
  //alert(allVals.length); return false;  
  if(allVals.length <=0)  
  {  
   alert("Please select row.");  
  }  
  else {  
   //$("#loading").show(); 
   WRN_PROFILE_DELETE = "Are you sure you want to delete this row?";  
   var check = confirm(WRN_PROFILE_DELETE);  
   if(check == true){  
    //for server side
    /*
    var join_selected_values = allVals.join(","); 
    
    $.ajax({   
      
     type: "POST",  
     url: "delete.php",  
     cache:false,  
     data: 'ids='+join_selected_values,  
     success: function(response)  
     {   
      $("#loading").hide();  
      $("#msgdiv").html(response);
      //referesh table
     }   
    });*/              //for client side
     $.each(allVals, function( index, value ) {
      $('table tr').filter("[data-row-id='" + value + "']").remove();
     });
    

   }  
  }  
 });

JavaScript Function to Delete Single Record

Step 5: Below jQuery script is used to delete single records from the HTML table.

jQuery('.remove-row').on('click', function(e) {
  WRN_PROFILE_DELETE = "Are you sure you want to delete this row?";  
   var check = confirm(WRN_PROFILE_DELETE);  
   if(check == true){
    $('table tr').filter("[data-row-id='" + $(this).attr('data-id') + "']").remove();
   }
 });

Conclusion:

1. Initialization: Start by including jQuery and Bootstrap files for the necessary functionalities.
2. HTML Table: Define the structure of the HTML table with checkboxes to select rows and a delete button to initiate the deletion process.
