大师们好：我想要复选框中选中的value值显示到输入框中，改怎么弄，谢谢！
<form id="form" method="post">

<input type="text" value=" " name="originalprice"/><!--输入框-->

<input type="checkbox" value="news" name="box[]" />
<input type="checkbox" value="music" name="box[]" />
<input type="checkbox" value="read" name="box[]" />
<input type="checkbox" value="global" name="box[]" />
