jQuery $這個被點擊元素

Question

我有下面的腳本，點擊（從模態窗口）發送圖像的URL到輸入字段。我也將同一個網址imgurl發送到<div class="preview-image>，以便在插入時顯示它。

var BusiPress_Configuration = { 
    init : function() { 
     this.files(); 
    }, 

    files : function() { 
     if ($('.busipress_upload_image_button').length > 0) { 
      window.formfield = ''; 

      $('.busipress_upload_image_button').on('click', function(e) { 
       e.preventDefault(); 
       window.formfield = $(this).parent().prev(); 
       window.tbframe_interval = setInterval(function() { 
        jQuery('#TB_iframeContent').contents().find('.savesend .button').val(busipress_vars.use_this_file).end().find('#insert-gallery, .wp-post-thumbnail').hide(); 
       }, 2000); 
      if (busipress_vars.post_id != null) { 
       var post_id = 'post_id=' + busipress_vars.post_id + '&'; 
      } 
       tb_show(busipress_vars.add_new_file, 'media-upload.php?' + post_id +'TB_iframe=true'); 
      }); 

      window.original_send_to_editor = window.send_to_editor; 
      window.send_to_editor = function (html) { 
       if (window.formfield) { 
        imgurl = $('a', '<div>' + html + '</div>').attr('href'); 
        window.formfield.val(imgurl); 
        window.clearInterval(window.tbframe_interval); 
        tb_remove(); 
        $('.preview-image img').attr('src',imgurl); 
       } else { 
        window.original_send_to_editor(html); 
       } 
       window.formfield = ''; 
       window.imagefield = false; 
      } 
     } 
    } 
} 

BusiPress_Configuration.init(); 

發送圖像URL給編輯的DIV工作正常，但這樣做是爲了在頁面上該分區的每個實例。我一直在玩$(this)和closest()，看我是否可以將插入本地化到輸入附近的特定div，但沒有任何運氣。任何幫助將不勝感激。謝謝！

假設你已經可以選擇按鈕（我改成了「按鈕，選擇」爲同時），使用parent獲取父td然後找到孩子div改變。這將使您的按鈕到達最近的div。

$("button-selector").parent('td').find("div")
