Error Using JSON.parse With Internet Explorer
Jan 4, 2010
I have client-side javascript that is using AJAX to receive JSONs from a server-side database-querying php script. My application is working fine in firefox and chrome. IE8 is giving me trouble, however. The error I get is:
Message: 'JSON' is undefined
Line: ###
Char: #
Code: 0
URI: http://...
Does anyone know if their is a different function or library include I need for IE8 in order to work with JSONs, more specifically JSON.parse()?

I have a feeling that the solution to my problem is stupidly simple, but crawling through Google has provided me with none.
I'm trying to handle the login process on one of my clients' site using the AJAX functionality provided by jQuery.
Here is the $.ajax() call in question:
$.ajax({
"cache": false,
"complete": function()
{
[Code]....
I have already set the Content-Type header of the response to application/json, which made no difference. I also tried text/html and text/plain, but in these cases Internet Explorer shows the JSON as HTML or plain text in the browser window... *sigh*
Googling also gave me the suggestion to just use text/plain and eval() the response myself, but I remember reading elsewhere that this is pretty unsafe. I am unsure on the specifics on this, though.

my site seems to be working perfectly on firefox but when I access it on internet explorer everything loads fine but there is a yellow marker on the status bar of IE saying there are errors on the page. I copied the source into dreamweaver to check for browser specefic bugs but the only bugs that came up were that in Netscape. So any idea why this is happening? The link to my site is in my profile.

I don't know if that's a problem from jquery or not, so it's a question for the moment :)
I've this : Webpage error details User Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0; .NET CLR 1.1.4322; .NET CLR 2.0.50727; InfoPath.2; .NET4.0C; .NET4.0E; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729; Zune 4.7)

I have a problem with the javascript (I'm using jQuery) in a facebook application in internet explorer 7:[URL]..In the background some facebook like iFrames are loaded and when the user clicks on one of those attractions on that map the attraction should zoom out and the like buttons of this attracion should appear. I have only a very old pc with msie 7 running and it seems to load those iFrames again and again and nothing else works. I doesn't have any other debugging tool then IE Developer Toolbar but that doesn't seem to show any javascript errors or information.

This piece of code is used for an AJAX function, it works perfectly well in all other browsers than internet explorer.
// JavaScript Document
// store xmlhttp in a variable
var xmlHttp;
function xmlHttpRequestObject () {
// assume we're working with a newer browser
try {
xmlHttp = new XMLHttpRequest();
}
catch(e) {
// assume IE6 or older
try {
xmlHttp = new activeXObject("Microsoft.XMLHTTP");
}
catch(e) { }
} .....

I am using HAPedit for HTML/Javascript and it used to work alright by clicking Display -> Browse with -> Default Browser(Internet Explorer). But since last one or two days it gives the following error:
"The page cannot be displayed"
and the following is shown in the URL bar
[URL]
But, however, if I navigate to the file by using File -> Open of the IE, the result is shown correctly.

I have dozens of pages on my website which have just started showing an 'Error on page' message at the bottom left of Internet Explorer 8.0. These messages do not appear when using Mozilla Firefox. My website is www.lakesandcumbria.com and an example of a page showing the error message is [URL] which contains a javascript drop down list. All other pages using this type of drop down list are showing the same error message (dozens of them).

I'm trying to set up a quick poll using AJAX which all works fine when using Firefox but running into issues via IE.
$(function() {
$('.error').hide();
$(".button").click(function() {[code]....
The issue I'm having is that although the form is being processed OK with data being captured in the database, once the form is submitted, the above script just seems to stop the rest of the page from loading. This only happens on IE and it must be something to do with the success function but as I'm new to JavaScript I don't know what I'm doing wrong.

I seem to have come across a weird issue in internet explorer.I've been working on doing regular expressions for a register form, and I've checked it in Firefox, and Chrome and it seems to work for both of them but yet it doesn't work for Internext Explorer 6 - 8.The issue is that the drop down boxes (select fields) dont seem to be recognised for RegEx in I.E. this is causing an issue for me as I want it to work in ALL common web browers as well as keeping the whole form standard.
I've pasted a snippet of code below to show you what I've done.This one below is the original one which just checks if the field entry is blank
function check(theForm)
{
var checker;[code]...
If you have any Ideas about what I can do to make it work in I.E. I would be most greatful. Also if anyone knows how to do and RegEx on a checkbox that would help me quite a bit too.

So this works just fine in FF. In IE7 I am getting this error. I can see my content load in the background, when I hit ok it takes me to a page cannot be displayed page. If I comment out:
<script type="text/javascript" src="js/moodalbox.js"></script>
It doesnt present that error, but that is obviously not an option. Here is my code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />[CODE]......

Can anyone explain me why you need to add open and close parenthesis to
a JSON text in order to use eval() to parse it?
For example:
var json = "{a: 'abc', b: 'def'}";
var obj1 = eval("(" + json + ")"); //ok!
var obj2 = eval(json); //syntax error!
why are parenthesis necessary?

I am having difficulty displaying a specific key from a json file. I am trying to parse the following json file using query:
[URL]
I am using this type of function to parse the data:
$.each(json.route,function(i,route){
<!--add a paragraph tag to the results div and enter the speficied key-->
$("#results").append('<p>Result: '+ route +'</p>');
Using this I am able to print all the keys from the route but I am not able to print a specific key.
What I want to do is just get the results for the key "fuelUsed" using this method:
$("#results").append('<p>Result: '+ route.fuelUsed+'</p>');
But I never get back any data that way. Am I not specifying my key correctly?

I'm having trouble figuring out what's going on with IE6's
Msxml2.XMLHTTP object. I have two feed addresses in this stripped down
version of my code below. Both work fine in Firefox (using the
XMLHttpRequest object), but only the thinkgeek one works in IE. In the
processFeed function, it shows the problem - the first alert shows 0
for the wikihow feed in IE, though it can still display the
responseText. Any insight? Code:

How does one find the value of a drop down in Internet Explorer?
The form below works in Firefox and Safari. But not in Internet
Explorer. Can someone tell me how to code this so IE understands it?
<script language="javascript">
function copyDescription() {
document.myForm.Description.value=document.myForm. MakeDescription.value
}
</script>
<form name="myForm" id="myForm">
<SELECT name="MakeDescription" onChange="copyDescription();">
<OPTION selected value="">Choose</OPTION>
<OPTION>A</OPTION>
<OPTION>B</OPTION>
<OPTION>C</OPTION>
</SELECT>
<br /><br />
<input name="Description" id="Description" type="text" />
