网页透明层 - 请帮助!! [英] Layer Transparent in Web Page - Please help!!

问题描述

亲爱的朋友们，


我的名字是Pamela，我对javascript一无所知，

但是我想问一下它是否提供解决方案这个

我的问题。


我在css层的网页上有一张图片：


< DIV ID = MyLayer

STYLE =" position：absolute; top：68px; left：563px;

宽度：640px;高度：480px;">

< IMG src =" ReportImageBox_12.54.52.png" width = 640 height = 480>< / IMG>

Dear friends,

My name is Pamela, I do not know anything about javascript,
but I would like to ask if it offers a solution to this
problem of mine.

I have an image on a web page within a css layer:

<DIV ID=MyLayer
STYLE = "position: absolute;top:68px; left:563px;
width:640px;height:480px;">
<IMG src="ReportImageBox_12.54.52.png" width=640 height=480></IMG>
</DIV>

I need that the parts of this layer which have a certain color
(for instance "white") be rendered transparent.

My question. Is it possible to have a simple javascript function
to incorporate in the web page which does this??

Thank you very much

这一层中有任何不透明的东西

只有一张图片...


让你透明背景图片你自己是问题


但是......也许这个图像已经透明了？

你只有使用带有PC的Internet Explorer才会遇到麻烦吗？ br />

there is anything opaque in this layer as is
only an image ...

make your transparent background image yourself is the issue

But ... perhaps this image is allready transparent ?
and you have troubles only with Internet Explorer with a PC ?

是的，你需要一个IE Windows（Mac它的OK）破解png图像

渲染。


问Google：IE hack png css

和... soluce：

亲爱的Stephane


你的解决方案是针对png问题的（我在考虑）

一般，对于任何图像）。

然而，因为ie6仍然不支持png

透明度


我正在实现它并且有两个问题应该很简单一个

谁知道javascript


1.它假设com ponent放在一个外部文件中：

BEHAVIOR：url（" pngbehavior.htc"）

因为我以编程方式生成代码我需要它来合并

组件

在网页中。如何修改上述调用以在页面内运行

组件？


< public：component>

< public：attach event =" onpropertychange"的OnEvent = QUOT;的PropertyChanged（）" />

< script>

......

}


< / script>

< / public：component>


2.即阻止弹出窗口。有没有办法逃避它？


谢谢!!

Dear Stephane

Your solution is specific for the png problem (I was thinking in
general, for any image).
It is however useful to have as ie6 still not supporting png
transparency

I am implementing it and have 2 problems which should be simple for one
who knows javascript

1. It assumes the component is placed in an external file:
BEHAVIOR: url("pngbehavior.htc")
since I generate the code programmatically I need it to incorporate the
component
in the web page. How should the above call be modified to run the
component from within the page??

<public:component>
<public:attach event="onpropertychange" onevent="propertyChanged()" />
<script>
......
}

</script>
</public:component>

2. ie blocks the popups. Is there a way to elude it?

Thank you!!

只有gif和png可以有透明背景


gif图片：任何浏览器都可以吃它:-)


png图片：单独的IE Win打破这种格式（想想我）


休息我不知道：我没有PC

only gif and png can have transparent background

gif images : any browser can eat it :-)

png images : alone IE Win breaks with that format (do think I)

for rest I don''t know : I haven''t a PC
