jsp后一个窗口传值给前一个窗口，子父窗口之间的传值
1.新建两个页面 一个是Parent.html
<htmlxmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>父窗体</title>
<script language="JavaScript" type="text/javascript">
function OpenWindow() {
window.open(
"son.html",
"newwindow",
"height=100, width=400, toolbar =no, menubar=no, scrollbars=no, resizable=no, location=no, status=no")
}
function setValue(value) {
document.getElementById("txt_Value").value = value;
}
</script>
</head>
<body>
<form id="form1" name="form1" method="post" action="">
<label> <input type="text" name="txt_Value" id="txt_Value" />
</label> <label> <input type="button" name="btn_ShowClose"
id="btn_ShowClose" value="打开一个窗口" onclick="OpenWindow();" /> </label>
</form>
</body>
</html>
另一个是子窗体son.html :
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0Transitional//EN""http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><htmlxmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>子窗体</title>
<script language="javascript" type="text/javascript">
function Close() {
var zhi = document.getElementById("mytext").value；
window.opener.setValue(zhi);
window.close();
}
</script>
</head>
<body>
<form id="form1" name="form1" method="post" action="">
<input type="text" placeholder="请输入值" id="mytext">
<label><input type="button" name="btn_Close" id="btn_Close"
value="确定" onclick="Close();" /> </label>
</form>
</body>
</html>
