javascript - 在同一脚本中编写另一个函数后，javascript 函数停止工作

问题描述

我正在做员工休假管理系统。批准和不批准按钮在开始时工作正常。但是在编写代码以在同一模式中显示员工详细信息后，批准和不批准按钮停止工作。现在它给出了错误。有人知道出了什么问题吗？

控制器

//admin approve leave 
public function approveLeave() {

    $id = $this->input->post('id');
    $result = $this->Admin_Model->approve($id);

    if(!$result){

        // something went wrong

        $data = array(
            "value" => $id,
            "error" => true,                
            "msg" => "something went wrong"
        );

        $this->output
        ->set_content_type('application/json')
        ->set_output(json_encode($data));

        return;
    }


    // approved leave

    $data = array(
        "value" => $id,
        "error" => false,
        "msg" => "successfully updated"
    );

    $this->output
    ->set_content_type('application/json')
    ->set_output(json_encode($data));

}

看法

<div id="showleave">
                <h4 class="mb-4">Pending Requests</h4>
                    <?php
                        foreach ($leave as $row) {  
                        if($row->status != "1")
                         {                          
                            echo '
                            <ul class="list-unstyled">
                                <li class="media border-bottom border-top py-3">
                                    <img class="mr-3" src="http://via.placeholder.com/64x64" alt="Generic placeholder image">
                                    <div class="media-body">
                                      <h5 class="mt-0 mb-1">'.$row->user_name.'</h5>
                                      <p class="mb-0 mt-0">'.$row->leave_start.' to '.$row->leave_end.'</p>
                                      <p class="mt-0">'.$row->leave_type.'</p>
                                      <button type="button" class="detailButton" href="<?php echo $id; ?>" data-id="'.$row->id.'" data-name="'.$row->user_name.'" data-toggle="modal" value="'.$row->id.'">View Request</button>
                                    </div>
                                </li>               
                            </ul>
                            ';
                        }
                        }
                    ?>
                </div>

解决方案

利用

$(document).on('click','#declinebtn',function(){})而不是$('#declinebtn').click(function(){}).

像这样更改您的视图代码：

<div id="showleave">
<h4 class="mb-4">Pending Requests</h4>
<?php
foreach ($leave as $row) {
    if($row->status != 1)
    {
        ?>

        <ul class="list-unstyled">
            <li class="media border-bottom border-top py-3">
                <img class="mr-3" src="http://via.placeholder.com/64x64" alt="Generic placeholder image">
                <div class="media-body">
                    <h5 class="mt-0 mb-1"><?= $row->user_name ?></h5>
                    <p class="mb-0 mt-0"> <?= $row->leave_start.' to '.$row->leave_end ?></p>
                    <p class="mt-0"><?= $row->leave_type ?></p>
                    <button type="button" class="detailButton" href="<?php echo $row->id; ?>" data-id="<?= $row->id ?>" data-name="<?= $row->user_name ?>" data-toggle="modal" value="<?= $row->id ?>">View Request</button>
                </div>
            </li>
        </ul>
        <?php
    }
}
?>

通过这个我认为你的问题将得到解决
