JavaScript How to check all checkboxes inside an specific table with one button check all checkboxes inside div jquery,check all checkboxes inside

I have many dinamic tables, each one creates a dinamic master checkbox inside an input and several checkboxes inside td's (each one has a different ID). The idea is once I check or uncheck the master checkbox, every checkbox inside THAT specific table check/uncheck. (Some checkboxes inside table are previously check or uncheck from DDBB)

Here is a simple HTML trying to emulate what I want to do:

function testing() {

  if ($("#masterSwitch1").prop("checked") == true) {
    $('table[id^="table1"]').each(function() {
      $('td[class^="clientAct"]').attr("checked");
      $('td[class^="clientAct"]').prop("checked", true);
    });
  } else {
    $('table[id^="table1"]').each(function() {
      $('td[class^="clientAct"]').removeAttr("checked");
      $('td[class^="clientAct"]').prop("checked", false);
    });
  }

  if ($("#masterSwitch2").prop("checked") == true) {
    $('table[id^="table2"]').each(function() {
      $('td[class^="clientAct"]').attr("checked");
      $('td[class^="clientAct"]').prop("checked", true);
    });
  } else {
    $('table[id^="table2"]').each(function() {
      $('td[class^="clientAct"]').removeAttr("checked");
      $('td[class^="clientAct"]').prop("checked", false);
    });
  }
}

This code is worked it,so you can try this..!

$(".testing").on("change",function(){
  var id = $(this).attr('id');
  var tableID = $(this).data('id');

  if($('#'+id+'').prop("checked") == true) {
      $('#'+tableID+'').find('.clientAct').attr("checked", true);
      $('#'+tableID+'').find('.clientEje').attr("checked", true);
  } else {
      $('#'+tableID+'').find('.clientAct').attr("checked", false);
      $('#'+tableID+'').find('.clientEje').attr("checked", false);
  }
});

Please try this

$("#masterSwitch1").on("change", function(){
  

  if($("#masterSwitch1").is(':checked')){
    $('#table1 input[type=checkbox]').each(function() {
        var checkbox=$(this);
        checkbox.prop("checked",true)
    });
  }else{
    $('#table1 input[type=checkbox]').each(function() {
        var checkbox=$(this);
        checkbox.prop("checked",false)
    });
  }
})

$("#masterSwitch2").on("change", function(){
  

  if($("#masterSwitch2").is(':checked')){
    $('#table2 input[type=checkbox]').each(function() {
        var checkbox=$(this);
        checkbox.prop("checked",true)
    });
  }else{
    $('#table2 input[type=checkbox]').each(function() {
        var checkbox=$(this);
        checkbox.prop("checked",false)

Answer:3

Simply you could do as below, you do need to use each loop

Also you have use id as id="s2" which is duplicated, you should use unique id in document.

function testing() {

if( $("#masterSwitch1").prop("checked") == true) {
    
    $('#table1').find('.clientAct').attr("checked", true);
} else {
    $('#table1').find('.clientAct').attr("checked", false);
}

if( $("#masterSwitch2").prop("checked") == true) {
    
    $('#table2').find('.clientAct').attr("checked", true);
} else {
    
    $('#table2').find('.clientAct').attr("checked", false);
}
}

<input type="checkbox" onchange="testing()" id="masterSwitch1"> Try me!
<table id="table1">
   <thead>
      <tr>
         <th>Table 1</th>
      </tr>
   </thead>
   <tbody>
      <tr>
         <td>Name</td>
         <td><input type="checkbox" class="clientAct" id="s1"></td>
         <td><input type="checkbox" class="clientEje" id="s2" checked></td>
      </tr>
      <tr>
         <td>Last Name</td>
         <td><input type="checkbox" class="clientAct" id="s3" checked></td>
         <td><input type="checkbox" class="clientEje" id="s4"></td>
      </tr>
   </tbody>
</table>

<input type="checkbox" onchange="testing()" id="masterSwitch2"> Try me 2!
<table id="table2">
   <thead>
      <tr>
         <th>Table 2</th>
      </tr>
   </thead>
   <tbody>
      <tr>
         <td>Name 2</td>
         <td><input type="checkbox" class="clientAct" id="s1"></td>
         <td><input type="checkbox" class="clientEje" id="s2" checked></td>
      </tr>
      <tr>
         <td>Last Name 2</td>
