我有这个 index.php 文件;
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Proj</title>
<script type="text/javascript">
function openWindow() {
window.open("popup.php", "popup_id", "scrollbars=no,resizable,width=200,,left=300,top=300,height=200");
}
</script>
</head>
<body>
<form name="form1" action="">
<input name="initialdata" type="text" value="initial data" />
<input type="button" value="Send" onClick="openWindow()" />
</form>
</body>
</html>
和这个 popup.php 文件
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>popup</title>
<script type="text/javascript">
function putData() {
//How to copy from that file -> document.formname.popupdata.value to
//index.php -> document.form1.initialdata.value???
window.close();
}
function loadData() {
//how to get the value "initial data"
//from index.php -> document.form1.initialdata.value????????????
}
</script>
</head>
<body onLoad="loadData();">
<form name="formname" action="">
<input name="popupdata" type="text" value="" />
<input type="button" value="Send" onClick="putData()" />
</form>
</body>
</html>
如何从 index.php -> document.form1.initialdata.value 获取值“初始数据”以及如何从 popup.php -> document.formname.popupdata.value 复制到 index.php -> document.form1 .initialdata.value??
