IE will not submit unless file field is correctly specified

Permalink | Explorer 5-6 Windows, Explorer 7 | 0 comments
Reported on 30 August 2007

When a file upload field has an incorrectly specified file, browsers respond in different ways.

IE solves the problem by preventing form submission.
This approach is reasonably sensible, however it would be much better if IE popped up a warning dialog saying "File not found".

Firefox takes a totally different approach; it lets the server sort out an appropriate response.
It means I have to code the server for this use case (good practice anyhow) and I can put up my own warning messages.

In summary, the Firefox approach needs a bit more coding but gives me complete control over the page. IE means well, but leaves my users confused and unable to leave the page.

Border rendering bugs with border-collapse and hidden cell

Permalink | Explorer 5-6 Windows, Explorer 7, Mozilla, Opera, Safari, iCab | 4 comments
Reported on 5 April 2007

When border-collapse: collapse; is applied to a table with borders and a hidden cell, all browsers have issues:

Firefox hides border in the table entirely if all the cells in the row are hidden but the row element is visible. This can be resolved by hiding the row element.

Internet Explorer renders the border of the row that has all it's cells hidden. This can be resolved by hiding the row element.

Opera doesn't render all of the top border of a table if any of the top row cells is hidden and there is atleast one visible cell on the row.

Safari and iCab don't render the td border at all if a cell is hidden.

Floated elements overflow container incorrectly

Permalink | Explorer 5-6 Windows, Explorer 7 | 0 comments
Reported on 4 April 2007

When using relatively positioned floating elements inside a container, which has an overflow other than visible, the elements behave as if the container has overflow: visible. This occurs in (at least) Internet explorer 6 and 7.

IE: no hyperlink above element using AlphaImageLoader filter

Permalink | Explorer 5-6 Windows, Explorer 7 | 1 comments
Reported on 26 March 2007

I first noticed the problem when I tried to use a PNG+alpha background in an element that contains an hyperlink (see test page). The hyperlink would not work in certain area, which I later identified as non transparent areas of the background image.

It seems as if the filter "steals" mouse events in non transparent areas, regardless of its z-order (no click, no cursor shape change).

Workaround: add the filter to an element with position: static, and there must be a position: relative child element.

Incorrect handling of the this-keyword in the global scope by IE7

Permalink | Explorer 5-6 Windows, Explorer 7 | 3 comments
Reported on 20 March 2007

If you define a function as a member of the window object in IE7, the keyword this obviously refers to the wrong object:


window.myFunction = function() {
   return (this === window);
}

A call to myfunction() in IE7 would incorrecty yield false. This problem also affects exception handling. Predefined event-handlers like onload are not affected.

IE6win won't allow cloneNode to other frames

Permalink | Explorer 5-6 Windows, Explorer 7, iCab | 0 comments
Reported on 5 February 2007

IE6 throws errors when an element is cloned from one frame and appended to another. This includes pop-ups.

The test page shows two frames and buttons which trigger various combinations of cloning from (hidden) elements in a frame and appending to another.

In Firefox 1.5.09, all permutations work. In Safari 1.3.2, all permutations work at some times, but silent crashes occur at others

IN IE6win, an unappended clone can be held in a variable in another frame (eg. its parent), but it must be appended to the frame from whence it came.

I think this means that DOMloading in pop-ups must be created afresh OR cloned from elements in the pop-up itself.

checkbox not checked with setAttribute

Permalink | Explorer 5-6 Windows, Explorer 7 | 2 comments
Reported on 2 February 2007

Attempting to set a generated checkbox element to a checked status fails in IEwin6:it doesn't matter whether setAttribute is called before or after appending.

Don't have a workaround besides using el.checked=true after appending (which is precisely want I wanted to avoid!)

Same problem doesn't affect disabled attribute. PS. see also testpage elements for select.selected and select.size

Floats with position: relative and percentage-value body margin inaccurately repositioned on page resize

Permalink | Explorer 5-6 Windows, Explorer 7 | 0 comments
Reported on 11 December 2006

If your document's body uses a percentage value as a left or right margin, then position:relative (even without left/top/bottom/right declared), floated elements inside a containing block with a defined width, will not reposition accurately (or at all) as the page is resized. Reloading the page after resizing fixes the problem - just like a Netscape 4 bug.

Iframe width set incorrectly

CSS Bug in MSIE 6 - Selector with an ID and a Class on the Same Element

Permalink | Explorer 5-6 Windows | 1 comments
Reported on 10 April 2006

Let's say that you have an element with an id of id. This element can have either of two different classes, classOne or classTwo. (Either you're swapping the className in script, or it can have different classes on different pages.)

Your CSS might look like this:

#id.classOne { some styles }
#id.classTwo { some different styles }

In MSIE 6, the #id.classTwo style will never be applied - unless it is put in a separate style tag or style sheet.

Floats and block widths applied in the incorrect order

Permalink | Explorer 5-6 Windows, Explorer 7, Explorer Mac | 2 comments
Reported on 9 December 2005

This bug is caused by IE not calculating position of floats correctly. As far as I can tell the left edge of the content is calculated and then the width is applied, the correct behaviour is to apply the width and then see where the content should be layed out due to any floats.

Text disappears when element is removed with innerHTML

Permalink | Explorer 5-6 Windows, Explorer 7, Explorer Mac | 0 comments
Reported on 28 November 2005

When you remove an element by innerHTML='' it's possible to re-append the element to the document. In Explorer Windows, though, the text goes missing.

Explorer Mac loses track of the element when it's been removed. So in this browser elements don't stay in hyperspace after they've been emptied from the innerHTML.

Margin inheritance bug

Permalink | Explorer 5-6 Windows | 5 comments
Reported on 12 September 2005

When using a margin on a parent container with a child container inside and in there form elements then the margin of the parent container gets inherited to the form elements, and it can't be removed by a margin 0.

The affected form elements are input types, checkboxes, radiobuttons and textareas

In Internet Explorer 6.0 and higher, setting html, body {position: relative;} while in strict mode causes the browser to disallow scrolling. I don't know of any real-world applications where this would be a problem, but it's still a bug.

In Safari the entire body disappears if you set position: relative on the HTML first, and then on the BODY. Safari crashes if you check BODY, then HTML, then uncheck BODY.

Workarounds include using quirks mode, or playing it safe and avoiding setting positioning to the html element.

Ordered list rendering with width on LIs

Permalink | Explorer 5-6 Windows | 8 comments
Reported on 8 July 2005

It seems that if I attempt to specify the width of a list item tag (<li>) using either a CSS class or a STYLE attribute, IE does not increment the number in front of list each item. i.e. instead of a list with items numbering 1, 2, 3, and 4, I get a 4 item list numbering 1, 1, 1, and 1.

(ppknote: This bug is very similar, but not identical, to width on ol/ul.)

float left and background problem

Elements don't display correctly if they have a background color and a child element that uses float: left.

The #content{background: #FFFFFF;} declaration is the source of the problems. Remove it and the hidden element displays fine.

Border around iframe

Setting a border around an iframe creates a padding-right and padding-bottom twice as large as the border.
This bug occurs in MSIE 6 in Strict Mode. It seems the iframe's document width is computed according to the traditional box model, while the iframe itself is computed according to the W3C box model.

getAttribute("HREF") is always absolute

Permalink | Explorer 5-6 Windows, Explorer 7, Explorer Mac, Opera | 1 comments
Reported on 25 February 2005

In some browsers getAttribute("HREF") on an A element returns a complete URL, even if the HREF attribute in the source specified a relative path. In others it returns the exact text of the attribute in the source, which may be relative.

All browsers put the complete, resolved, URL for an A element in its .href property. In Explorer (Win and Mac) and Opera 8 the same value is returned by getAttribute("HREF"), while Mozilla (FF1.0), Safari and Konqueror (3.2.2) return the source value. I consider the latter behaviour to be correct.

The test case contains two links, the first absolute and the second relative, and reports the values of .href and getAttribute("HREF") for each. It is the last reported value that differs.

CSS 'bottom' and 'right' properties in IE (Strict)

Permalink | Explorer 5-6 Windows, Explorer Mac | 8 comments
Reported on 24 January 2005

The CSS 'bottom' property can be used to place an absolutely positioned element relative to the bottom of the containing block. When 'top' is also specified, the element should stretch from 'top' to 'bottom'. However, when both are specified, IE ignores 'bottom' and instead bases the height of the element on its contents (shrink-to-fit).

IE similarly ignores the CSS 'right' property when 'left' is specified.

Only IE 6.0 and Firefox 1.0 tested. No pure CSS (non-javascript) workaround found yet.

Back and forward between named anchors doesn't update window.location

Permalink | Explorer 5-6 Windows, Explorer 7, Opera, Safari | 2 comments
Reported on 18 January 2005

When navigating between named anchors in IE, the window.location object changes to reflect the change in the URL. This is correct. However, the window.location object should also change when you use the back or forward buttons, or the history.back() and history.forward() methods, to move between these anchors, and in IE 6.0 and IE 6.1, it does not.

Opera has exactly the opposite bug: it never shows the hash.

Explorer ignores closing </li> tags

Permalink | Explorer 5-6 Windows | 3 comments
Reported on 17 January 2005

Internet Explorer on Windows completely ignores closing LI tags.

This means that if the list item contains a block level link, the blank space after the LI will be rendered as a blank line.

It also means that if elements are nested within the list, but not within a LI (this is invalid HTML, but people still do it), IE will treat them as if they are in the preceding LI. This modifies both the DOM and the response to CSS.

Box model of TDs

Permalink | Explorer 5-6 Windows, Explorer 7, Explorer Mac, Mozilla, Opera | 0 comments
Reported on 14 January 2005

The box model of a td turns out to be unchangeable in Explorer (Win and Mac), Mozilla and Opera. Explorer Mac forces it into the traditional model, while the other browsers force it into the W3C box model.

Explorer Windows, though, switches the TDs to the correct box model when you use table-layout: fixed. Unfortunately this does not work in the other browsers.
