After working on it all day, I finally found a solution online

Note: The problem is the method of calling the child page on the parent page. . . . .

Parent page: parent.html

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>parent</title>
<script>
 function parentFunction() {
  alert(&#39;function in parent&#39;);
 }
 function callChild() {
  child.window.childFunction();
  /*
   child 为iframe的name属性值，
   不能为id，因为在FireFox下id不能获取iframe对象
  */
 }
</script>
</head>
<body>
<input type="button" name="call child"  value="call child" onclick="callChild()"/>
<br/><br/>
<iframe name="child" src="./child.html" ></iframe>
</body>
</html>

Child page: child.html

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<title>child</title>
<script>
 function childFunction() {
  alert(&#39;function in child&#39;);
 }
 function callParent() {
  parent.parentFunction();
 }
</script>
</head>
<body>
<input type="button" name="call parent" value="call parent" onclick="callParent()"/>
</body>
</html>
