jQuery.fn.css('border-width') is seriously flawed

[boecko]

see: ​http://jsfiddle.net/boecko/3EdaS/2/[[BR]]

1.4.2 -> border-width 4px 4px (right)

1.4.3 -> border-width (nothing!!)

1.4.4rc2 -> border-width auto auto

[boecko]

sorry .. wrong url

​http://jsfiddle.net/boecko/3EdaS/2/

[boecko]

the above output is from WebKit. Firefox reports this:

1.4.2 -> border-width 4px (still right, css('border-width') is empty)

1.4.3 -> border-width (nothing!!)

1.4.4rc2 -> border-width auto auto

The test case is reproduceable and this seems like a valid issue.

As a already said in #7283

this is definitely the desired result now

• I think it's not good to change the expected result between minor versions.
  

• a cleaner solution would be:
  

a) to introduce a unit converter function (unitInPixels), which can be called if desired

b) a cssCurrent - function or something , which reports back the current value in pixels or whatever.

3. for mmToPixels i'm using following function to get the dpi

    function getDpi() {
        var mm = 100000;
        var dpitest = $('<div id="dpitest" style="disply:none;width:'+ mm + 'mm;height:10px"/>');
        var inch2mm = 25.4;
        dpitest.appendTo('body');
        var px = dpitest.outerWidth();
        var dpi = Math.round(px / (mm / inch2mm) * 1000) / 1000;
        dpitest.remove();
        return dpi;
    };

The behavior for >=1.4.3 is markedly regressed

[boecko]

next one in here RC3 ... ​http://jsfiddle.net/boecko/3EdaS/

1.4.2 -> border-width 4px 4px (right)
1.4.3 -> border-width (nothing!!)
1.4.4rc2 -> border-width auto auto
1.4.4rc3 -> border-width (nothing!!)

Confirmed. This issue is very, very broken.

use .css("border-width-top")

this is fucked up .... csshooks may be fine, but have you ever heard the 4 words "compatibility between minor versions"?

so why don't implement the basic versions via csshooks like it was and let it extend to whatever nifty feature you want?

Think about the plethora of plugins which breaks, because of that! my jquery-plugin (here in action ​http://www.logowein.de/designer.php?_theme=polaroid) reads the css-value of a html-template (e.g in mm) to modify this value via a JQ UI-Slider.

Now, because some genius thinks he can break a stable api, i have to maintain to versions of that.

BTW: Where in hell is the behavior change documented? ​http://blog.jquery.com/2010/10/16/jquery-143-released/ this way to little info for my taste .. Couldn't you just give a simple function/hint for the old behavior?

This isn't even consistent! Apparently you should get the computed value as number, BUT you have to unset it via string and not null (#7233). Don't tell me, that this well thought: just to clarify

$.css('width') -> gets a computed number instead of a string
$.css('width',null) doesn't work, because it exepects a string
-> $.css('width', "") 

[boecko]

JESUS!..

​http://jsfiddle.net/boecko/3EdaS/14/

instead of ..

$('#foo').css('borderWidth');

i have to use

$.style($('#foo')[0], 'borderWidth');

now, to get the expected behavior. really nice.

[boecko]

BTW: Your suggestion

use .css("border-width-top")

doesn't work.So how on earth can you close this bug!?

@boecko, use .css('border-top-width") or .css("borderTopWidth")

​http://jsfiddle.net/3EdaS/16/

[boecko]

@ kswedberg agreed .. it works .. but it's not intuitive, because i'm interested in the style value.

Issue still at large and very frustrating. Furthermore, chrome and opera (latest builds) deal with it by reading the general border-width value as one would hope, internet explorer (8&9) and safari effectively and such call and walk on past, but in firefox calling css("border-width") breaks the code. At a minimum this represents a lack of cross browser support.
