单击 jquery-tabledit 中的编辑按钮时如何启用下拉选择框？

编程问答 2022-05-27

问题描述

我有一个带有下拉选择框的表格，我想默认禁用它（出于安全目的）。现在，当单击 jquery-tabledit 中的编辑按钮时，我希望再次启用它。我怎么能做到这一点？ 每当评论“Multiselect JS”时，它都可以工作，但否则不行。我需要“Multiselect JS”，以便它显示为下拉选择框。

这是注释“Multiselect JS”时的样子：

这个问题不同，因为它包括：

<!--Multiselect JS-->
<script>
    $(document).ready(function () {
        $('.roles_checkBox').multiselect({
            includeselectAllOption: true,nonSelectedText: '--Select Role--'
        });
    });
</script>

<!--User Approval-->
    <td>
        <form method='POST'>
            if ($row_approved['admin_approved'] == 'Approved') {
            echo "<select disabled name='selectBox' onchange='this.form.submit()'>
                <option value='Approved' selected>Approved</option>
                <option value='disapproved'>disapproved</option>
            </select>";
            } else if ($row_approved['admin_approved'] == 'disapproved') {
            echo "<select name='selectBox' onchange='this.form.submit()'>
                <option value='Approved'>Approved</option>
                <option value='disapproved' selected>disapproved</option>
            </select>";
            }
            echo "
        </form>
    </td>

    <!--User Roles-->
    <td>
    <form method='POST'>
    <select disabled class='roles_checkBox' multiple='multiple' name="roles_checkBox[]"
            onchange='this.form.submit()'>
    </select>
    <?PHP
    echo "
    </form>
    </td>

<script>
    $(document).ready(function () {
        $('#editable_table').tabledit({

            // when click on save; action_user_2.PHP gets called
            url: 'action_user_2.PHP',// where data will be sent
            
            data: {approved_status: approved_status},columns: {
                identifier: [0,"user_id"],editable: [[1,'first_name'],[2,'last_name'],[3,'email']]
            },// hide the column that has the identifier
            hideIdentifier: true,// activate focus on first input of a row when click in save button
            autoFocus: true,// activate save button when click on edit button
            saveButton: true,restoreButton: false,onSuccess: function (data,textStatus,jqXHR) {
                var htmlString = "<?PHP echo 'User information has been updated'; ?>";
                alert(htmlString);

                // custom action buttons
                if (data.action === 'delete') {
                    $('#' + data.id).remove();
                }
            }
        });

    $(document).on("click",".tabledit-edit-button",function() {
    //get closest tr and then find slectBox and disable same
    $(this).closest("tr").find("[name=selectBox]").removeAttr('disabled')
    $(this).closest("tr").find("[name*=roles_checkBox]").removeAttr('disabled')
    })
  });

  $('#editable_table').DataTable();
</script>

<!--Multiselect JS-->
<script>
    $(document).ready(function () {
        $('.roles_checkBox').multiselect({
            includeselectAllOption: true,nonSelectedText: '--Select Role--'
        });
    });
</script>

解决方法

在您的代码中，您仅从 select-box 中删除 disable 但是，从 mutliselect 插件动态生成的元素仍然被禁用，因此您需要从中删除 disable元素也是如此。

演示代码： 

$('#editable_table').Tabledit({
  //some codes...
  columns: {
    identifier: [0,"user_id"],editable: [
      [1,'first_name'],[2,'last_name'],[3,'email'],]
  },hideIdentifier: true,autoFocus: true,saveButton: true,restoreButton: false,onSuccess: function(data,textStatus,jqXHR) {
    var htmlString = "<?php echo 'User information has been updated'; ?>";
    alert(htmlString);

    // custom action buttons
    if (data.action === 'delete') {
      $('#' + data.id).remove();
    }
  }


});

$(document).on("click",".tabledit-edit-button",function() {
  //get closest tr and then find slectbox and disable same
  $(this).closest("tr").find("[name=selectbox]").removeAttr('disabled')

  $(this).closest("tr").find("[name*=roles_checkbox],.dropdown-toggle ").removeAttr('disabled') //remove attr from button as well
  $(this).closest("tr").find(".dropdown-toggle").removeClass('disabled') //remove disable class from button
})
$('.roles_checkbox').multiselect({
  includeSelectAllOption: true,nonSelectedText: '--Select Role--',buttonWidth: '150px'
});
