I am receiving a JavaScript error in IE7: you don't have permission.
In IE8+, Chrome, Firefox, and Safari there is no problem with this code.
Why does this error only occur in IE7? And how would I change my code using JaScript and Ajax?
Code:
login: function () {
var a = location.href;
if (loginCurrentFullUrl != null && loginCurrentFullUrl != "") {
a = loginCurrentFullUrl;
}
var b = location.href.substring(location.href.length - 1);
if (b.indexOf("/") > -1) {
a = location.href.substring(0, location.href.length - 1);
}
location.href = "/pc/login/?url=" + encodeURIComponent(a);
},
or
var o = location.toString();
Error code:
('you don't have permission')
var a = location.href;
var o = location.toString();
I tried:
document.location.href;
window.location.href;
I also tried:
document.domain = 'mydomain.com';
Neither has worked.

We have embedded a form via iFrame on our website. When the form has been sent, a new URL should be called.
On the desktop (Chrome browser), the redirect works. On iOS on the iPhone, the window freezes when you submit the form.
Do you know what is causing this or what is triggering this error in the code?
Here is our Code:
<script type="text/javascript">
(function () {
var d = document,
s = d.createElement('script');
s.src = 'https://kitarinocockpit.nemborn.com/Script/NemPlads/preregister-v1.0.0.1.js';
s.id = 'nemplads-script';
s.setAttribute('data-timestamp', +new Date());
window.addEventListener('success', function (e) {
const items = document.location.search.substr(1).split("&");
for (let index = 0; index < items.length; index++) {
const getParam = items[index].split("=");
if (getParam[0] === 'id') {
document.location.href = 'https://www.kitarino.net/bestatigung-platzanfrage?id=' + decodeURIComponent(getParam[1]);
break;
}
}
});
(d.head || d.body).appendChild(s);
})();
</script>
This is the code from http://jsfiddle.net/2gou4yen/ to ignore x-frame-option.
var iframe = document.getElementsByTagName('iframe')[0];
var url = iframe.src;
var getData = function (data) {
if (data && data.query && data.query.results && data.query.results.resources && data.query.results.resources.content && data.query.results.resources.status == 200)
loadHTML(data.query.results.resources.content);
else if (data && data.error && data.error.description) loadHTML(data.error.description);
else loadHTML('Error: Cannot load ' + url);
};
var loadURL = function (src) {
url = src;
var script = document.createElement('script');
script.src = 'http://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20data.headers%20where%20url%3D%22' + encodeURIComponent(url) +'%22&format=json&diagnostics=true&env=store%3A%2F%2Fdatatables.org%2Falltableswithkeys&callback=getData';
document.body.appendChild(script);
};
var loadHTML = function (html) {
iframe.src = 'about:blank';
iframe.contentWindow.document.open();
iframe.contentWindow.document.write(html.replace(/<head>/i, '<head><base href="' + url + '"><scr' + 'ipt>document.addEventListener("click", function(e) { if(e.target && e.target.nodeName == "A") { e.preventDefault(); parent.loadURL(e.target.href); } });</scr' + 'ipt>'));
iframe.contentWindow.document.close();
}
loadURL(iframe.src);
This works well.
But with a problem.
For the first time, it doesn't work. And when you refresh once, it works.
So, is there a solution that works without refresh?
Have you tested in other browser?
In my opinion it's browser problem.
Test it in Safari, Google Chrome, FireFox.
In other way you can save the content in your server as html using serverside code and load it from server.
Hi i am making google chrome extension and stucked with error
Uncaught TypeError: Cannot read property 'getSelected' of undefined
My code is below
called function getQueryString(); inside if statement is creating error

var newUrl = tab.replace(reExp, 'page=' + current);
console.log(newUrl);
chrome.runtime.sendMessage({redirect: newUrl});
});
}
help can bring cheers
Your script key_event.js is a content script. It is running in the context of the website rather than the extension context. As a result it cannot use all of the chrome API (like chrome.tabs).
In order to get the current website URL from inside the website context, you can use window.location.href. You can also get the query string using window.location.search. So no need to query chrome.tabs here.
Something in the lines of
var tabURL = window.location.href;
var queryString = window.location.search;
Ok, so you know the error, but why on earth am I getting it?
I get no errors at all when this is run locally, but when I uploaded my project I got this annoying syntax error. I've checked the Firebug error console, which doesn't help, because it put all my source on the same line, and I've parsed it through Lint which didn't seem to find the problem either - I just ended up formatting my braces differently in a way that I hate; on the same line as the statement, bleugh.

The problem is your script on your server is in one line, and you have comments in it. The code after // will be considered as comment. That's the reason.
function ToServer(cmd, data) { var xmlObj = new XMLHttpRequest(); xmlObj.open('POST', 'handler.php', true); xmlObj.setRequestHeader('Content-type', 'application/x-www-form-urlencoded'); xmlObj.send(cmd + data); xmlObj.onreadystatechange = function() { if(xmlObj.readyState === 4 && xmlObj.status === 200) { if(cmd == 'cmd=push') { document.getElementById('pushResponse').innerHTML = xmlObj.responseText; } if(cmd == 'cmd=pop') { document.getElementById('messages').innerHTML += xmlObj.responseText; } if(cmd == 'cmd=login') { if(xmlObj.responseText == 'OK') { self.location = 'index.php'; } else { document.getElementById('response').innerHTML = xmlObj.responseText; } } } };}function Login() { // Grab username and password for login var uName = document.getElementById('uNameBox').value; var pWord = document.getElementById('pWordBox').value; ToServer('cmd=login', '&uName=' + uName + '&pWord=' + pWord);}// Start checking of messages every secondwindow.onload = function() { if(getUrlVars()['to'] != null) { setInterval(GetMessages(), 1000); }}function Chat() { // Get username from recipient box var user = document.getElementById('recipient').value; self.location = 'index.php?to=' + user;}function SendMessage() { // Grab message from text box var from = readCookie('privateChat'); var to = getUrlVars()['to']; var msg = document.getElementById('msgBox').value; ToServer('cmd=push','&from=' + from + '&to=' + to + '&msg=' + msg); // Reset the input box document.getElementById('msgBox').value = "";}function GetMessages() { // Grab account hash from auth cookie var aHash = readCookie('privateChat'); var to = getUrlVars()['to']; ToServer('cmd=pop','&account=' + aHash + '&to=' + to); var textArea = document.getElementById('messages'); textArea.scrollTop = textArea.scrollHeight;}function readCookie(name) { var nameEQ = name + "="; var ca = document.cookie.split(';'); for(var i=0;i < ca.length;i++) { var c = ca[i]; while (c.charAt(0)==' ') c = c.substring(1,c.length); if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length); } return null;}function getUrlVars() { var vars = {}; var parts = window.location.href.replace(/[?&]+([^=&]+)=([^&]*)/gi, function(m,key,value) { vars[key] = value; }); return vars;}
You're missing a semi-colon:
function ToServer(cmd, data) {
var xmlObj = new XMLHttpRequest();
xmlObj.open('POST', 'handler.php', true);
xmlObj.setRequestHeader('Content-type', 'application/x-www-form-urlencoded');
xmlObj.send(cmd + data);
xmlObj.onreadystatechange = function() {
if(xmlObj.readyState === 4 && xmlObj.status === 200) {
if(cmd == 'cmd=push') {
document.getElementById('pushResponse').innerHTML = xmlObj.responseText;
}
if(cmd == 'cmd=pop') {
document.getElementById('messages').innerHTML += xmlObj.responseText;
}
if(cmd == 'cmd=login') {
if(xmlObj.responseText == 'OK') {
self.location = 'index.php';
}
else {
document.getElementById('response').innerHTML = xmlObj.responseText;
}
}
}
}; //<-- Love the semi
}
Additional missing semi-colon:
// Start checking of messages every second
window.onload = function() {
if (getUrlVars()['to'] != null) {
setInterval(GetMessages(), 1000);
}
}; //<-- Love this semi too!
I think you can adapt divide and conquer methodology here. Remove last half of your script and see whether the error is coming. If not, remove the first portion and see. This is a technique which I follow when I get an issue like this. Once you find the half with the error then subdivide that half further till you pin point the location of the error.
This will help us to identify the actual point of error.
I do not see any problem with this script.
This may not be the exact solution you want, but it is a way to locate and fix your problem.
It looks like it's being interpreted as being all on one line. See the same results in Fiddler 2.
This problem could do due to your JavaScript code having comments being minified. If so and you want to keep your comments, then try changing your comments - for example, from this:
// Reset the input box
...to...
/* Reset the input box */
Adding a note: very strangely this error was there very randomly, with everything working fine.
Syntax error missing } after function body | At line 0 of index.html
It appears that I use /**/ and //🜛 with some fancy Unicode character in different parts of my scripts for different comments.
This is useful to me, for clarity and for parsing.
But if this Unicode character and probably some others are used on a JavaScript file in comments before any JavaScript execution, the error was spawning randomly.
This might be linked to the fact that JavaScript files aren't UTF-8 before being called and read by the parent page. It is UTF-8 when the DOM is ready. I can't tell.
It seems there should be added another semicolon in the following code too:
// Start checking of messages every second
window.onload = function() {
if(getUrlVars()['to'] != null) {
setInterval(GetMessages(), 1000);
}
}; <---- Semicolon added
Also here in this code, define the var top of the function
function readCookie(name) {
var i;
var nameEQ = name + "=";
var ca = document.cookie.split(';');
for(i=0;i < ca.length;i++) {
var c = ca[i];
while (c.charAt(0)==' ') c = c.substring(1,c.length);
if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length);
}
return null;
}
"Hm I think I found a clue... I'm using Notepad++ and have until recently used my cPanel file manager to upload my files. Everything was fine until I used FireZilla FTP client. I'm assuming the FTP client is changing the format or encoding of my JS and PHP files. – "
I believe this was your problem (you probably solved it already). I just tried a different FTP client after running into this stupid bug, and it worked flawlessly. I'm assuming the code I used (which was written by a different developer) also is not closing the comments correctly as well.
I have a script i have been battling with now for like a week.
I have a page which has a div with id ("content"). Now I loaded some content, a form contained in a div tag to be specific, into this div VIA Ajax, and it is displaying fine
Now, the challenge is - When the form is submitted, Im am calling a function that will disable all the field on the element in that div tag. I always get the error "undefined".
It seems that the div, that i brought in to the page isn't recognized by javascript..
I have searched google, bing, yahoo..i just havent found the solution yet...
Please, what do I do??

This code is on the main page where the javascript is
<div id="dMainContent">
</div>
</body>
</html>
And finally, the content of the page i am loading via ajax..
<div style="width:738px" id="CompForm">
<div class="tdright">
<?php echo $btnNm; ?>
</div>
</div>
That's the code..
Thanks
The issue is with div tag (id "CompForm") which is not a HTML form.
"elements" is a collection of the form element not div element. So when trying to access div.elements the property is undefined.
See MSDN, form.elements is part of DOM level 1 (according to MSDN)
http://msdn.microsoft.com/en-us/library/ms537449%28v=VS.85%29.aspx
Add your Javascript functions or external JS file to the original page.
this is not JavaScript....
doc.getElementById(contId).elements
but is used in your JavaScript... you will definitely not get anything. (null)
I don't think this is valid either:
theId[i].disabled == false
EDIT: Note per comments: this is NOT the answer :) See comments for details of why.
Left as an answer simply as a learning aid aid as suggested.
Shouldn't
xmlHttp.onreadystatechange = loadingContent;
be
xmlHttp.onreadystatechange = loadingContent();
or
loadingContent();
and that function should return a value if you want to assign it like that...
