怎调用另外一个页面里的JavaScript函数啊

2个窗口必须有关系才行,比如:
var xxx = "ok"
a = window.open("b.htm")
在b.htm可以用
alert(opener.xxx)

解决方案 »

  1.   

    知道窗口对象为winX,可以用
    winX.methodXX()
    winX.变量d
      

  2.   

    ----- a.asp -----<input type=button value=ok onclick="document.frames[0].show();">
    <iframe src='b.asp'></iframe>----- b.asp -----Is b.asp
    <script language="javascript">
    <!--
      function show()
      {
        alert('clement');
      }
    //-->
    </script>

                用window.openr打开的子父窗口之间的操作跟框架的是不一样的，子窗口和父窗口之间有opener来联系。而源窗口要访问子窗口要通过其句柄来操作。以下小例子希望能帮助新手更了解他们的操作。</P>
