與JS確認+ PHP

Question

刪除鏈接，這是刪除鏈接

<div class="artworkdelete"> 
    <a href="javascript:void(0);" id="del_<?=$artworkDetails['artwork_id'] ?>_<?=$temp_cat_id; ?>" onclick="deleteThisArtWork(this.id)">Delete</a> 
</div> 

顯然，當點擊該鏈接時，門戶網站會自動刪除數據，我認爲這是一個Ajax的事情，因爲網頁不刷新。於是我就問添加一個確認彈出要求用戶點擊yes或如果他想刪除的數據;以及確認框之內，它應該提到的數據的名稱，如如

被刪除無

"are you sure you want to delete row_title ?" 

這裏的deleteThisArtWork（）

 function deleteThisArtWork(artwork_id){ 
         var artwork_id = artwork_id.split('_'); 
         var cat_id=artwork_id[2]; 
         artwork_id = artwork_id[1]; 
         //$('#divStatus').html('processing request, please wait'); 
         //$(".pleaseWait").dialog("open"); 
         openLightBox();

          type: 'POST',

          data: 'deleteartwork=yes&artwork_id='+artwork_id+'&category_id='+cat_id, 
          success: function(msg){ 
          //alert(msg); 
          msg = 'done'; 
          var status=msg; 
          var deleted='';

            if(atid[2]==cat_id){endpoint = i-1;artcounter=artcounter+1;}

             rowHeadLast = this;

          } 
         }); 

     } 

這是相當長的，我想我並不需要所有的這些東西，如果需求只是刪除數據時「是」從點擊的功能在確認彈出框

現在，這裏的刪除PHP函數

function deleteArtWork($artwork_id,$category_id){ 

    $artwork_cat_lookup_del = "delete from artwork_category_lookup where artwork_id = '$artwork_id' AND category_id='$category_id'"; 
    if(mysql_query($artwork_cat_lookup_del)){  
     $userObj = new User(); 
     $allArtWorkByCat = $userObj->allArtWorkByCat($category_id); 
     for($itr = 0; $itr<count($allArtWorkByCat); $itr++){ 
      $ordr = $itr + 1; 
      $art_id = $allArtWorkByCat[$itr]['artwork_id']; 
      $updateSQL = "update artwork_category_lookup set artwork_display_order='$ordr' where artwork_id = '$art_id' AND category_id = '$category_id'"; 
      mysql_query($updateSQL); 
     } 
     $action = $userObj->userActions('Artwork id: '.$artwork_id.' is deleted', 'Gallery'); 
     $userObj->setActionintoDB($action); 
     echo 'done'; 
    } 
    else echo 'DBDelete:error'; 
    return;

我不認爲你想開始改變上面的代碼，因爲這是用來傳遞相關數據通過AJAX的PHP腳本。

你需要的是一個JavaScript提示攔截鏈接點擊給用戶一個選擇繼續或取消刪除操作。它是否正確？

http://www.tizag.com/javascriptT/javascriptconfirm.php

在「deleteThisArtWork」 javascript函數，你需要顯示提示符的開始。

function deleteThisArtWork(artwork_id){ 
    var answer = confirm("Are you sure you want to delete this record?"); 
    if (answer){ 
     //do the rest of the function as usual, i.e. delete row via ajax. 
    }else{ 
     return false; 
    } 
} 

應從意外刪除記錄沒有至少不必在確認彈出不慎點擊並停止用戶！

如果要在確認彈出動態中生成文本，您需要將動態文本作爲變量傳遞給「deleteThisArtwork」方法，或者使用某個javascript從頁面上的其他元素中提取該文本。
