Question

大家好我想尝试使用jquery复制文本框值，但我不想在插件上使用add 这是我的代码

 <div class="form-group col-lg-4 col-md-4 col-sm-12 col-xs-12"> 
  <input type="text" id="visor_node_token" name="view" value="Hello World">
 </div>
 <input type="button" name="view" value="Copy" class="btn btn-primary" onclick="copy_node_token()" />
function copy_node_token()
{
  var node = $("#visor_node_token").val();
  $(node).select();
  document.execCommand("Copy");
}`

我无法复制文本值。请帮我解决这个问题
