function coord(el,prop) in JQuerySpinBtn.js not work properly in IE

[Aray]

The plugin Spin Button is greate, It is very usefull to me. Thank you for your greate work.

But there were a little problem in JQuerySpinBtn.js, wich I download from ​http://www.softwareunity.com/sandbox/jqueryspinbtn/JQuerySpinBtn.js.

the function coord(el,prop) not work properly in IE if document.body's padding or margin is not ZERO.

Following is the offcial release of code

function coord(el,prop) {

var c = el[prop], b = document.body;

while ((el = el.offsetParent) && (el != b)) {

if (!$.browser.msie

(el.currentStyle.position != 'relative'))

c += el[prop];

}

return c;

}

Maybe it should be change to like following:

function coord(el,prop) {

var c = el[prop], b = document.body;

while ((el = el.offsetParent) /*&& (el != b)*/) {

if (!$.browser.msie

(el.currentStyle.position != 'relative'))

c += el[prop];

} if(el == b)

break;

return c;

}

The attachment SpinButton.zip contain two demon to show the problem, their files are all the same, except JQuerySpinBtn.js

break;

return c;

}

I am so sorry that I have made a mistake, to fix the problem, the correct code should be as following.

function coord(el,prop) {

var c = el[prop], b = document.body;

while ((el = el.offsetParent) /*&& (el != b)*/) {

if (!$.browser.msie

(el.currentStyle.position != 'relative'))

c += el[prop];

if(el == b)

break;

}

return c;

I found another problem when using IE. if the IE window have a scroll bar, and the scroll bar are note in Top or in Left position. It will not work properly

The reason is that, In IE, the Event.y is the distance of document top to mouse point, this distance is NOT including the scroll bar position. so does the Event.x.

To solve this problem, find line "var y = e.pageY

e.y;" in JQuerySpinBtn.js, add following code below this line

if($.browser.msie) {

x += document.documentElement.scrollLeft;

y += document.documentElement.scrollTop;

}

I don't have enough knowledge of compatibility of JavaScript between IE,Firefox, blabla. The code may make some change.
