Answer 1

document.getElementById("showHtml").innerHTML = "<img src='../../images/cls/btn_Up.gif' alt='收缩' class='title_img' onclick='down()' />";innerHTML是个属性，不是方法。

Answer 2

document.getElementById("showHtml").innerHTML="<img src='../../images/cls/btn_Up.gif' alt='收缩' class='title_img' onclick='down()' />";

Answer 3

头一次看见innerHTML还有你这种写法的，写错了小伙子，innerHTML是属性，不是方法function up()
{  
  //var idName=
  document.getElementById("showHtml").innerHTML="<img src='../../images/cls/btn_Up.gif' alt='收缩' class='title_img' onclick='down()' />";
  //$("#showHtml").html("<img src='../../images/cls/btn_Up.gif' alt='收缩' class='title_img' onclick='down()' />");
  //$(idName).hide();
  document.getElementById("editView").style.display=="none";
   
}
