Question

我想通过将while循环中生成的动态值传递给ajax来删除记录。我想在jquery中传递$ ef值。（即）在删除图像的onclick事件中删除示例hrms trail.doc文件。现在onclick图像标记事件不会显示任何操作

 while($fet=mysql_fetch_assoc($sql1))
            {

              $file=$fet['f_name'];
              $ef=$fet['ef_id'];
               $next1 = basename($file);
              echo "<h3><a  class=doc  href='".$file."' title='".$file."' download><p style='margin-left:1cm;'>".$next1."</a>";
              echo '<img src="image/delete1.png" id=".$ef."width="10" height="10" title="Remove" onclick="javascript:myFunction();">';

            }

我的jquery ajax代码

           <script>
          function myFunction()
          {   
           var rmvfile=$("doc").val();
           $.ajax({
           type:'post',
           url:'hrms/delete_emp_file.php',
           data:{rmvfile: rmvfile},
           success:function(msg){
           if (msg.length> 0) {
               alert(msg);
                } }

            });
            }

enter image description here

delete_emp_file.php中的php代码

 $s=$_POST['rmvfile'];
 include "config.php";
 $echeck="delete from employee_file where ef_id='".$_POST['rmvfile']."'";
 $echk=mysql_query($echeck);
 $ecount=mysql_num_rows($echk);

 if($ecount>='1')
 {
  echo "file deleted";
 }

Answer 1

试试这个，

while($fet=mysql_fetch_assoc($sql1))
     {
        $file=$fet['f_name'];
        $ef=$fet['ef_id'];
        $next1 = basename($file);
        echo "<h3><a  class='doc'  href='".$file."' title='".$file."'><p style='margin-left:1cm;'>".$next1."</a>";
         echo '<img src="image/delete1.png" id=".$ef." width="10" height="10" title="Remove" onclick="javascript:myFunction();">';
     }

你的AJAX：

function myFunction()
 {   
     var rmvfile=$(".doc").val();
       $.ajax({
            type:'post',
            url:'hrms/delete_emp_file.php',
            data:{rmvfile: rmvfile},
            success:function(msg){
                   if (msg.length> 0) {
                             alert(msg);
                               } 
                       }
                });
 }

在你的delete_emp_file.php中，

$echeck="delete from employee_file where ef_id='".$_POST['rmvfile']."'";

您可以传递$s代替$_POST['rmvfile']

$echeck="delete from employee_file where ef_id='$s'";

Answer 2

您希望传递$ ef变量：

while($fet=mysql_fetch_assoc($sql1))
     {
        $file=$fet['f_name'];
        $ef=$fet['ef_id'];
        $next1 = basename($file);
        echo "<h3><a  class='doc' id=".$ef." href='".$file."' title='".$file."'><p style='margin-left:1cm;'>".$next1."</a>";
         echo '<img src="image/delete1.png" width="10" height="10" title="Remove" onclick="javascript:myFunction();">';
     }

您的Ajax代码

function RemoveFile(id)
 {   
       $.ajax({
            type:'post',
            url:'hrms/delete_emp_file.php',
            data:{rmvfile: id},
            success:function(msg){
                   if (msg.length> 0) {
                             alert(msg);
                               } 
                       }
                });
 }
$(".doc").on('touchstart click',function() {
var file_id = $(this).prop('id');
RemoveFile(file_id);
});

如果您想要传递href和id，请执行以下操作：

   function RemoveFile(id,link)
     {   
           $.ajax({
                type:'post',
                url:'hrms/delete_emp_file.php',
                data:{fid: id, rmvfile: link},
                success:function(msg){
                       if (msg.length> 0) {
                                 alert(msg);
                                   } 
                           }
                    });
     }
    $(".doc").on('touchstart click',function() {
    var file_id = $(this).prop('id');
    var file_link = $(this).prop('href');
    RemoveFile(file_id,file_link);
    });

以下是我提到的从循环动态生成的删除图像代码

   <ul class="hoverbox">
   <?php
        for($k=0;$k<$cardslen;$k++)
        {
           echo '<li class="inlineclass" id="ss'.$imagenames[$k]->id.'">';
           echo '<div class="scrolllist"><div class="img-wrap" id="s'.$imagenames[$k]->id.'"><span class="close"  id="'.$imagenames[$k]->id.'">&times;</span>';
          echo '<img id="'.$imagenames[$k]->id.'" data-id="'.$imagenames[$k]->id.'~'.$folder.'" alt="'.$imagenames[$k]->title.'" class="imglarge" id="imgSmile<?php echo $k;?>" style="height: 120px;" src="../images/morfeoshow/'.$folder.'/thumbs/'.$imagenames[$k]->filename.'">';
       echo '</div>';
          echo '</li>';
        }
       ?>
     </ul>

这是脚本代码

   <script type="text/javascript" src="//code.jquery.com/jquery-1.9.1.js"></script>
     <script type="text/javascript">//<![CDATA[ 
     $(window).load(function(){
     $('.img-wrap .close').on('click', function() {
     var id = $(this).closest('.img-wrap').find('.imglarge').data('id');
      //alert(id);
      var r = confirm("Do you want to remove this image!");
       if (r == true) {
      $.ajax({
       url : "yoururl",
       type: "POST",
      data :{imageid:id},
      success: function(data)
       {
      //alert(data);
     $('#ss'+data).hide();
        $('#sss'+data).hide();
      $('#'+data).hide();
       $('#s'+data).hide();
      //location.reload();
       },});
    } 

  });
   });//]]>  

   </script>

在ajax文件上我只有代码删除mysql查询删除记录和从文件夹中删除图像的代码。在此代码中，ajax将删除图像，并且在成功ajax调用后隐藏删除图像并且页面不刷新。我认为此代码可以帮助您

我通过以下代码

解决了这个问题

 while($fet=mysql_fetch_assoc($sql1))
            { 

             $next=$fet['f_name'];
             $next1 = basename($next);
             $ef=$fet['f_id'];
             echo '<h4><a class="astext" href="'.$next.'" title="'.$next.'" target="_blank" download><p style="margin-left:1cm;">'.$next1.'</a>';
              echo '<img src="image/delete1.png" alt="delete" style="width:10px;height:10px" title="Remove" onclick="myFunction('.$fet['f_id'].');">';
            }


        function myFunction(fid)
     {   
      var  rmvfile=fid;
      if (confirm("Are you sure you want to Delete the file?") == true) {
      if(fid!='')
        {
         $.ajax({
         type:'post',
         url:'delete_adm_file.php',
         data:{rmvfile: rmvfile},
         success:function(msg){
         location.reload();
         }
         });
         } } }
