带有复选框的表 - 选中所有复选框并将值传递给AJAX脚本

Question

我在第一列中有一个带有复选框的表 - 当选中时，它执行一个AJAX脚本，用所选值更新PHP会话变量。这一切都运行良好但我现在需要扩展它以在第一列的顶部有一个复选框，以允许用户选择表中的所有项目并将所选项目的值（例如逗号分隔）传递为AJAX脚本的参数 - 假设我需要一个新脚本。

这是我到目前为止所拥有的：

＆＃13;

＆＃13;

$(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();
    });
  });
});

＆＃13;

<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>

＆＃13;

＆＃13;

＆＃13;

我在第一行添加了一个可用于选择所有项目的复选框 - 基本上相当于逐个点击每个复选框。不知道如何扩展或创建一个新脚本，点击它时检查每个复选框并将ID值传递给我可以包含在我的AJAX脚本中的变量？

Answer 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);
    });
});

Answer 2

添加了以下代码，可以解决这个问题：

$("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();
    });
  });
});

Answer 3

这个适用于多个table并且选择所有复选框。

Featuers：

• 根据全选复选框
选中/取消选中
• 点击单个复选框，只传递 id 和检查状态

从callUpdate

调用 AJax

// 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 );
    
  });
  
  
});
