Frameset 两页面互调控件技术案例

总共包含三个页面（Html），分别为Parent.Html、ChildA.Html、ChildB.Html

Parent.Html页面代码

<frameset cols="50%,*"> 
    <frame name="left" src="1.html"> 
    <frame name="right" src="2.html"> 
</frameset>

ChildA.Html页面代码

<html>
<head>
    <script>
        function setValue() {
          window.parent.document.getElementById("right").contentWindow.document.getElementById("txt2").value = document.getElementById("txt1").value;
        }
    </script>
</head>
<body>
    <input type="text" id="txt1" onkeyup="setValue()" />
</body>
</html>

ChildB.Html页面代码

<html>
<head>
    <script>
        function setValue() {
           window.parent.document.getElementById("left").contentWindow.document.getElementById("txt1").value = document.getElementById("txt2").value;
        }
