Table with Checkboxes - selected all Checkboxes and pass values to AJAX script

问题

I have a table with a checkbox in the first column - when checked this performs an AJAX script that updates a PHP session variable with the selected values. This is all working well but I now need to extend this to have a check box at the top of the first column to allow the user to select all items in the table and pass the value of the selected items (e.g. comma separated) as a parameter to the AJAX script - assuming I need a new script just for this.

Here's what I have so far:

$(document).ready(function() {
  $("input.select-item").click(function() {
    var productID = $(this).val();
    // Create a reference to $(this) here:
    $this = $(this);
    $.post('productSelections.php', {
      type: 'updateSelections',
      productID: productID,
      selectionType: 'single'
    }, function(data) {
      data = JSON.parse(data);
      if (data.error) {
        var ajaxError = (data.text);
        var errorAlert = 'There was an error updating the Product Selections';
        $this.closest('td').addClass("has-error");
        $("#updateSelectionsErrorMessage").html(errorAlert);
        $("#updateSelectionsError").show();
        return; // stop executing this function any further
      } else {
        $this.closest('td').addClass("success")
        $this.closest('td').removeClass("danger");
      }
    }).fail(function(xhr) {
      var httpStatus = (xhr.status);
      var ajaxError = 'There was an error updating the Product Selections';
      $this.closest('td').addClass("danger");
      $("#updateSelectionsErrorMessage").html(ajaxError);
      $("#updateSelectionsError").show();
    });
  });
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table class="table table-condensed table-striped table-bordered">
  <thead>
    <th><input type="checkbox" class="select-all checkbox" name="select-all" /></th>
    <th class="text-center" scope="col">Product ID</th>
    <th class="text-center" scope="col">Description</th>
  </thead>
  <tbody>

    <tr class="" id="85799">
      <td id="AT36288"><input type="checkbox" class="select-item checkbox" name="select-item" value="AT36288" /></td>
      <td>AT36288</td>
      <td>Apples</td>
      <td></td>
    </tr>
    <tr class="" id="85800">
      <td id="AT36289"><input type="checkbox" class="select-item checkbox" name="select-item" value="AT36289" /></td>
      <td>AT36289</td>
      <td>Bananas</td>
      <td></td>
    </tr>
    <tr class="" id="85801">
      <td id="AT36290"><input type="checkbox" class="select-item checkbox" name="select-item" value="AT36290" /></td>
      <td>AT36290</td>
      <td>Oranges</td>
      <td></td>
    </tr>
    <tr class="" id="85803">
      <td id="AT36292"><input type="checkbox" class="select-item checkbox" name="select-item" value="AT36292" /></td>
      <td>AT36292</td>
      <td>Grapes</td>
      <td></td>
    </tr>
  </tbody>
</table>

I've added a checkbox in the first row that can be used to select all items - essentially the equivalent of clicking each checkbox one by one. Not sure how to either extend or create a new script that when clicked checks each checkbox and passes the ID values to a variable that I can include in my AJAX script?

回答1:

$('.select-all').on('click', function(){
    var values = []; // will contain all checkbox values that you can send via ajax
    $('table > tbody input[type="checkbox"]').each(function(i, el) {
        $(el).prop('checked', true);
        values.push(el.value);
    });
});

Added this below code that did the trick:

$("input.select-all").click(function() {
    $("input.select-item").each(function() {
        $(this).trigger('click');
    });
});

$(document).ready(function() {

  $("input.select-all").click(function() {
    $("input.select-item").each(function() {
      $(this).trigger('click');
    });
  });
  $("input.select-item").click(function() {
    var productID = $(this).val();
    // Create a reference to $(this) here:
    $this = $(this);
    $.post('productSelections.php', {
      type: 'updateSelections',
      productID: productID,
      selectionType: 'single'
    }, function(data) {
      data = JSON.parse(data);
      if (data.error) {
        var ajaxError = (data.text);
        var errorAlert = 'There was an error updating the Product Selections';
        $this.closest('td').addClass("has-error");
        $("#updateSelectionsErrorMessage").html(errorAlert);
        $("#updateSelectionsError").show();
        return; // stop executing this function any further
      } else {
        $this.closest('td').addClass("success")
        $this.closest('td').removeClass("danger");
      }
    }).fail(function(xhr) {
      var httpStatus = (xhr.status);
      var ajaxError = 'There was an error updating the Product Selections';
      $this.closest('td').addClass("danger");
      $("#updateSelectionsErrorMessage").html(ajaxError);
      $("#updateSelectionsError").show();
    });
  });
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table class="table table-condensed table-striped table-bordered">

This one works well with multiple table with select all checkboxes.

Featuers:

Check/Uncheck on basis of select all checkbox
On individual checkbox click, only its id and check status is passed

Call your AJax from callUpdate

// This will work with multiple table items
// on page

$(document).ready(function(){
  
  function callUpdate( ids, isChecked ){
    alert( 'Check status is: ' + isChecked + '\nids:\n' + ids.join(', ') ); 
  }
  
  
  var allSelectAllCheckboxes = $('thead th:first .select-all');
  
  // On related checkbox clicked individually
  allSelectAllCheckboxes.closest('table').find('tbody .select-item').click(function(){
    
    var $el = $(this);
    callUpdate( [ $el.val() ], $el.prop('checked') );
  
  });
  
  // Look for master checkbox within table thead
  allSelectAllCheckboxes.click(function(){
    
    // Get clicked checkbox
    var $clickedCheckbox = $(this);
        isSelectAllChecked = $clickedCheckbox.prop('checked'),
        $targetCheckboxes = $clickedCheckbox.closest('table').find('[name=select-item]'),
        ids = [];

    
    // Enumerate through each target checkbx
    $targetCheckboxes.each( function(){

      // Set checkbox check/uncheck 
      // according to 'select all' status
      this.checked = isSelectAllChecked;
      
      // Push product id to collection
      ids.push( this.value );
    });
   
    // Call update using our proxy function
    callUpdate( ids, isSelectAllChecked );
    
  });
  
  
});
