ZeroClipboard.js使用一个flash复制多个文本框

<div id="J_pop_share">
  <input id="J_video_iframe1" value="<iframe src="http://caibaojian.com/book/"></iframe>" />
  <button id="J_copy_btn1">复制</button>
</div>

var clip = null;//ZeroClipboard.Client对象 
var current_id = null;//当前所在的文本元素id 
//指定ZeroClipboard.swf位置
ZeroClipboard.setMoviePath(location.protocol+"//club.pcauto.com.cn/js/ZeroClipboard.swf"); 
clip = new ZeroClipboard.Client();//创建ZeroClipboard.Client对象 
clip.setHandCursor(true);//鼠标移动到元素上之后显示手型 
clip.glue('J_copy_btn1','J_pop_share');
clip.setText($('#J_video_iframe1').val());
//添加复制成功之后的操作 
clip.addEventListener('complete', function() { 
  alert('复制成功'); 
});

<div id="J_pop_share">
  <div>
    <input id="J_video_iframe1" value="<iframe src="http://caibaojian.com/book/"></iframe>" />
    <button id="J_copy_btn1" class="btn-copy-text">复制</button>
  </div>
  <div>
    <input id="J_video_iframe2" value="<iframe src="http://caibaojian.com/book/"></iframe>" />
    <button id="J_copy_btn2" class="btn-copy-text">复制</button>
  </div>
  <div>
    <input id="J_video_iframe3" value="<iframe src="http://caibaojian.com/book/"></iframe>" />
    <button id="J_copy_btn3" class="btn-copy-text">复制</button>
  </div>
  <div>
    <input id="J_video_iframe4" value="<iframe src="http://caibaojian.com/book/"></iframe>" />
    <button id="J_copy_btn4" class="btn-copy-text">复制</button>
  </div>
</div>

//上面的代码
$(".btn-copy-text").each(function(i){
  var index =i+1;
  $(this).on('mouseover',function(){
    var button_id = $(this).attr('id');//复制div的id 
    //var text_id = button_id+'_text';//要复制的元素id 
    var text_id = 'J_video_iframe'+(index);
    move_swf(text_id , button_id); 
  }); 
}); 

//移动浮动flash div到指定的地方，从而只需要使用一个flash即可在多个地方实现复制功能 
function move_swf(text_id,button_id) { 
  //重新指定flash浮动div位置，用reposition 
  clip.reposition(button_id, 'J_pop_share');
  clip.setText($('#'+text_id).val()); 
}
