     <input type="button" name="Button" value="Button"
onclick="document.frames('ifrmname').location.reload()">

或
<input type="button" name="Button" value="Button"
onclick="document.all.ifrmname.document.location.reload()">

方案二:用iframe的id属性定位
<input type="button" name="Button" value="Button"
onclick="ifrmid.window.location.reload()">

终极方案:当iframe的src为其它网站地址(跨域操作时)
<input type="button" name="Button" value="Button"
onclick="window.open(document.all.ifrmname.src,'ifrmname','')">

问题：
我是打算使用上面的语句把数据库的连接字符串写入上一级网页的connstr文本框中，但是在执行时ie总报告“缺少十六进制数字”。
代码如下：
a="Provider=Microsoft.Jet.OLEDB.4.0; Data Source=E:\网站设计\dianming\upload\student.mdb;"
Response.Write("<script>")
    html="parent.document.getElementById(""connstr"").value="""+a+""""
    Response.Write(html+";")
Response.Write("</script>")
问题分析：
到底是怎么回事呢？经过试验发现，问题出在字符串a中的 “\” 上，    原来javascript中“\”是个特殊的字符，在很多场合需要转换，为此我使用“/“临时替代”\“一下，在使用到此字符串的时候再转换回来就可以了。
代码改写如下：
a="Provider=Microsoft.Jet.OLEDB.4.0; Data Source=E:\网站设计\dianming\upload\student.mdb;"
html=html+replace(a,"\","/")+""""
Response.Write("<script>")
    html="parent.document.getElementById(""connstr"").value="""+a+""""
    Response.Write(html+";")
Response.Write("</script>")
