我已经定义了这样的图像，最初我想将其隐藏

<input type="image"  id ="img" visible="false"  runat="server" src="../Images/calendar.jpg" onclick="displayCalendar(document.forms[0].txtvalue,''dd/mm/yyyy'',this);return false;"  />

但在特定条件下我想看到它
我已经在Java脚本中尝试过但没有得到

i have tried it in java script but not getting

document.getElementById("img").style.visibility='true'
      document.getElementById("img").style.display = ''
