位置图层适用于IE而非Firefox / Safari [英] Position layers works in IE not Firefox/Safari
问题描述
我有一个菜单，当你鼠标悬停时会弹出不同的图层。似乎
在IE 6中正常工作。我使用javascript动态定位图层
，因为当用户调整浏览器窗口大小时菜单会移动。在
Firefox或Safari浏览器中，图层的位置是0,0无论是什么，不管是什么，马上就可以了。左上角。
任何人都可以告诉我原因吗？
这是我用于定位图层的javascript函数。
下面是URL我正在建设的页面。
/ * START FUNCTION
******************* ******************************* *** /
函数positionLayer（layerID，imageName） {
//将图层''layerID''置于与图像相同的坐标处
''imageName''
var xPos，yPos，myElement，myLayer;
if（document.layers）{// NN4.x
xPos = document.images [imageName] .x;
yPos = document.images [imageName] .y;
}否则if（document.all）{// IE4 / IE5
xPos = getXPos（ document.images [imageName]）;
yPos = getYPos（document.images [imageName]）;
myLayer = document.all [layerID];
} else {// ass-u-me W3 DOM
myElement = document.getElementById（imageName）;
xPos = myElement.offsetLeft;
yPos = myElement.offsetTop;
myLayer = document.getElementById（layerID）;
}

I have a menu that pops up different layers as you mouse over. Seems to
work OK in IE 6. I position the layers dynamically with javascript
because the menu moves when users resize their browser window. In the
Firefox or Safari browsers the position of the layers is 0,0 no matter
what, right off the bat. Top left corner.
Can any one tell me why?
Here is my javascript function for positioning the layers.
Below that is the URL of the page I am building.
/* START FUNCTION
************************************************** ***/
function positionLayer(layerID, imageName) {
// positions layer ''layerID'' at the same coordinates as image
''imageName''
var xPos, yPos, myElement, myLayer;
if(document.layers) { // NN4.x
xPos = document.images[imageName].x;
yPos = document.images[imageName].y;
} else if(document.all) { // IE4/IE5
xPos = getXPos(document.images[imageName]);
yPos = getYPos(document.images[imageName]);
myLayer = document.all[layerID];
} else { // ass-u-me W3 DOM
myElement = document.getElementById(imageName);
xPos = myElement.offsetLeft;
yPos = myElement.offsetTop;
myLayer = document.getElementById(layerID);
}
/* END FUNCTION ************************************************** ***/

因为您的代码容易出错，所以不会按照您的想法行事，并且
你首先选择.all和.layers分支。

Because your code is error prone, doesn''t do what you think it does, and
you are taking the .all and .layers branches first.

[snup]在Firefox或Safari浏览器中，层的位置
无论如何都是0,0，关闭蝙蝠。左上角。可以告诉我为什么？

我猜（从变量名称）你可能正在使用元素
命名为ID。哪些不是，哪些不适用于
GetElemtById（x）
I''m guessing (from the variable name) that you may be using element
names as IDs. Which they aren''t and which will therefore not work in
GetElemtById(x)
