上个页面得到的值判断?
1.
<script   language= "javascript ">
function   abc()
{
var   the_unevaled_answer   =   "2   +   3 ";
var   the_evaled_answer   =   eval( "2   +   3 ");
alert( "the   un-evaled   answer   is   "   +   the_unevaled_answer   +   "   and   the   evaled   answer   is   "   +   the_evaled_answer);
}
</script>
<form>
<input   type= "button "   onclick= "abc() ">
<input   type= "text "   value= "1 "   id= "abc ">
<a   href= "实验.html "> 在 </a>
</form>


2.
<script   language= "javascript ">
function   yuan()
{
if(window.parent.abc.value== "1 ")
alert( "吃屎 ");
}
</script>
<select>
<option> 1 </option>
<option   selected> 2 </option>
</select>

<body   onLoad= "yuan(); ">
</body>


哪儿错了,我是按照某个网友说的做的

随面问一下

------解决方案--------------------
if(window.parent.abc.value== "1 ")改成if(window.parent.document.all.abc.value== "1 ")
估计那哥们写的时候没有加form、body吧。
