一個隱藏的div我有下面的代碼吧...顯示用JavaScript
<div id="viewFrame">
<iframe src="preview.php" name="previewFrame" width="100%" height="100%" style="display:none;"></iframe>
</div>
而且也：
<script type="text/javascript">
function previewFrame(){
document.preview.submit();
var preview = document.getElementById('viewFrame');
preview.style.display = 'block';
}
</script>
...哦，我也有
<form name="preview" action="preview.php" method="post" target="previewframe">
Some more code here...
</form>
它會隱藏div，但是當我嘗試提交表單時，它不會顯示iframe。任何人都知道什麼是錯的？
編輯：好吧，這裏是頁面的完整代碼：
<head>
<title>EasyPage</title>
<?
session_start();
if(!session_is_registered(myusername)){
header("location:main_login.php");
}
?>
<script type="text/javascript">
function insertlink(){
var url = prompt("URL:");
var text = prompt("Text:");
var link = "<a href=" + url + ">" + text + "</a>";
var linksbox = document.getElementById("links");
linksbox.value = linksbox.value + link;
}
function insertlink2(){
var url = prompt("URL:");
var text = prompt("Text:");
var link = "<a href=" + url + ">" + text + "</a>";
var contentbox = document.getElementById("content");
contentbox.value = contentbox.value + link;
}
function insertimage(){
var url = prompt("Image URL:");
var image = "<img src=" + url + " />";
var contentbox = document.getElementById("content");
contentbox.value = contentbox.value + image;
}
function insertlineopen(){
var line = "<p>";
var contentbox = document.getElementById("content");
contentbox.value = contentbox.value + line;
}
function insertlineclose(){
var line = "</p>";
var contentbox = document.getElementById("content");
contentbox.value = contentbox.value + line;
}
function previewFrame(){
document.preview.submit();
var preview = document.getElementById('previewFrame');
preview.style.display = 'block';
}
</script>
</head>
