已在脚本中使用 window.parent

所以我有这个：

/* ---------------------------- */
/* XMLHTTPRequest Enable */
/* ---------------------------- */
function createObject() {  
var request_type;
var browser = navigator.appName;
if(browser == "Microsoft Internet Explorer"){
request_type = new ActiveXObject("Microsoft.XMLHTTP");
}else{
request_type = new XMLHttpRequest();
}
return request_type;
}

var http = createObject();
/* -------------------------- */
/* INSERT */
/* -------------------------- */
var nocache = 0;
function insert() {
document.getElementById('insert_response').innerHTML = "Please Wait. "
var fID= encodeURI(document.getElementById('fID').value);
var kommentar= encodeURI(document.getElementById('kommentar').value);
nocache = Math.random();
// Pass variables like URL variable
http.open('get', 'insert.php?fID='+fID+'&kommentar=' +kommentar+'&nocache = '+nocache);
http.onreadystatechange = insertReply;
http.send(null);
}
function insertReply() {
if(http.readyState == 4){
var response = http.responseText;
document.getElementById('insert_response').innerHTML = ''+response;
}
}

我在index.php中有这个。您可以在那里写评论，然后按提交。当您按下提交时，它会运行此脚本:: 将变量传递给 insert.php，并在 insert_response 中显示响应。在 insert.php 中，它将注释插入数据库。

<?php
            mysql_query("INSERT INTO comments (fID, navn, kommentar, dato) VALUES ('$fID', '$pusername' ,'$kommentar', '$dato')") or
                die(mysql_error());
echo "Comment successfully";
?>
<script type="text/javascript">
if (window.parent) {
    window.parent.someFunction('hello world');
}
</script>

这是我的 insert.php^，正如你所看到的，我想向 window.parent 发送消息“hello world”。

但由于某种原因它无法工作，就像它不想将此脚本嵌入到 insert_response div 中一样。

现在window.parent，我想的是我的index.php，我有这个：

<script type="text/javascript">
function someFunction(msg) {
    alert(msg);
}
</script>

谢谢！

Insert.php，分派到客户端：

So i have this:

/* ---------------------------- */
/* XMLHTTPRequest Enable */
/* ---------------------------- */
function createObject() {  
var request_type;
var browser = navigator.appName;
if(browser == "Microsoft Internet Explorer"){
request_type = new ActiveXObject("Microsoft.XMLHTTP");
}else{
request_type = new XMLHttpRequest();
}
return request_type;
}

var http = createObject();
/* -------------------------- */
/* INSERT */
/* -------------------------- */
var nocache = 0;
function insert() {
document.getElementById('insert_response').innerHTML = "Please Wait. "
var fID= encodeURI(document.getElementById('fID').value);
var kommentar= encodeURI(document.getElementById('kommentar').value);
nocache = Math.random();
// Pass variables like URL variable
http.open('get', 'insert.php?fID='+fID+'&kommentar=' +kommentar+'&nocache = '+nocache);
http.onreadystatechange = insertReply;
http.send(null);
}
function insertReply() {
if(http.readyState == 4){
var response = http.responseText;
document.getElementById('insert_response').innerHTML = ''+response;
}
}

This do i have in index.php. And there you can write a comment, and press submit. When you press submit, it runs this script:: passing variable to insert.php, and show response in insert_response. In insert.php it inserts the comment to the database.

<?php
            mysql_query("INSERT INTO comments (fID, navn, kommentar, dato) VALUES ('$fID', '$pusername' ,'$kommentar', '$dato')") or
                die(mysql_error());
echo "Comment successfully";
?>
<script type="text/javascript">
if (window.parent) {
    window.parent.someFunction('hello world');
}
</script>

That is my insert.php^ and as you see i want to send message "hello world" to window.parent.

But it wont work for some reason, its like it dont want to innerhtml this script out to the insert_response div.

Now window.parent, what i thought, is my index.php where i have this:

<script type="text/javascript">
function someFunction(msg) {
    alert(msg);
}
</script>

Thanks!

Insert.php, dispactched to the client side:

为什么不简单地评估下载的代码，而不是嵌入 标记呢？当然，您必须信任服务器，并且响应必须始终是 javascript。

服务器端

<?php
            mysql_query("INSERT INTO comments (fID, navn, kommentar, dato) VALUES ('$fID', '$pusername' ,'$kommentar', '$dato')") or
                die(mysql_error());
echo "Comment successfully";
?>
if (window.parent) {
    window.parent.someFunction('hello world');
}

客户端

function insertReply() {
if(http.readyState == 4){
var response = http.responseText;
eval(response);
}
}

Instead of embed a <script tag, why don't simply eval the code downloaded? Of course, you must trust in the server, and the response must always be javascript.

SERVER SIDE

<?php
            mysql_query("INSERT INTO comments (fID, navn, kommentar, dato) VALUES ('$fID', '$pusername' ,'$kommentar', '$dato')") or
                die(mysql_error());
echo "Comment successfully";
?>
if (window.parent) {
    window.parent.someFunction('hello world');
}

CLIENT SIDE

function insertReply() {
if(http.readyState == 4){
var response = http.responseText;
eval(response);
}
}
