The issue in my case seemed to be caused by the the phone shutting down automatically due to an empty battery, although there may be other causes.

Having searched the web for a solution, there are a number of possible ways to fix the issue, with many appearing to work in some cases but not others:

• Simply turning “Set Automatically” to OFF then back ON.
• Going to Utilities > Clock and removing the World clocks, then switch the phone off and on again.
• Hard rebooting the phone by holding down the home and on / off button at the same time (until the Apple logo appears).

For me the problem was solved by carrying out the following actions:

1. Go to Settings > General > Date & Time.
2. Turn the “Set Automatically” option to OFF
3. Plug the phone into your computer and sync it using iTunes.
4. Go back to the Date & Time options page and switch “Set Automatically” back to ON.

You may have to try a combination of the methods listed above, or if you have an alternative solution to the problem then let us all know.

Using the .width() and .height() methods were working fine in every other browser but Safari, which I thought was a little bit odd. After trying to come up with an alternative method of coding calculating the heights and comparing them in FireBug and Web Inspector, I set about Googling the problem.

The only problem was that I had no idea what to search for, so started with the term “jquery height in safari”. The first result looked promising but took a fair bit of reading, although it proved to be worth while in the end. One comment pointed out that you should try to:

use jQuery(window).load() instead of jQuery(document).ready()

I tried this and straight away saw the results that were expected. The problem was that I didn’t really want to stop using the preferred document ready method ($(function() { … });), so searched the jQuery Bug Tracker for any sign of a bug report.

I eventually found one highlighting the exact problem I was having, issue #5521. The solution came in the form of a patch the document ready function that targets Safari.

+ if (jQuery.browser.safari && document.readyState != "complete") {
+ setTimeout( arguments.callee, 100 );
+ return;
+ }

It doesn’t look like this fix (nor any other form of solution) have been included in the latest nightly build, so I’m opting for the window load solution for now.

EDIT: Another solution to this problem is  to simply include any CSS files before the inclusion of the jQuery file. I found this by browsing the bug tracker and coming across ticket #3690.

Using the following code I managed to successfully read the width and height properties in FireFox 2/3, IE 6/7, Windows Safari 3/4 and Google Chrome, but the dimensions were not available in Opera (10).

$('')
	.load(function() {
		$('body').append(this);
		var w = this.width;
		var h = this.height;
		//..
	})
	.error(function() {
		//..
	})
	.attr('src', '/path/to/image.jpg');

After a fair bit of time playing around trying to debug this small snippet of code, I eventually discovered that if the image was appended to the DOM after the width and height had been read then Opera would report the values correctly.

		var w = this.width;
		var h = this.height;
		$('body').append(this);
		//..

Simply moving line 3 down to below the reading of dimensions solved this issue.

$("#id").css({opacity: 0.8});

It turns out that the latest version of jQuery (1.3.1) doesn’t believe that Opera 9.2 supports CSS opacity, and therefore it is ignored completely.

There are two possible fixes for this, the first is to simply upgrade Opera to a newer version (the latest is 9.6.3).

The second option is to tell jQuery that opera does support opacity using the following – or similar – within your script:

if ($.browser.opera) {
    $.support.opacity = true;
}

The Problem:

In the example below there is a standard button with 10px padding on all sides. Internet explorer chooses to add additional horizontal padding:

The solution:

After coming across this problem myself in the past, I eventually remembered that there are two CSS styles you can add to fix this bug feature in IE:

button {
	width: auto;
	overflow: visible;
}

As a group of web developers this key combination is something that comes almost naturally to us when editing and constantly saving code, so should prove a useful addition to the form that is not too difficult to implement.

I began by setting up the event observers to watch for the two required keys to be pressed.

Once the required key codes ( 17 and 83 ) were captured it should have been a case of simply referencing the form and applying the submit method.

document.forms['form_id'].submit();

To see if what was written so far would actually perform the desired action we tested the page using our default browser Firefox, only to discover we were receiving the following error:

document.forms.form_id.submit is not a function

This was all very puzzling but eventually resorting to a search on Google provided a number of answers.

It turns out that all our problems came back to the fact that the submit button on the form had been given the name of ‘submit’ – which is a JavaScript reserved word – resulting in ambiguity in the browser and therefore no longer referencing the method.

The solution to this is a very simple one – renaming the submit button to anything other than ‘submit’ or any of the reserved words in JavaScript.
