在网页中保存图像 [英] saving image in the webpage

问题描述

我想把2张图片叠加在一起。我隐藏第二张图片并显示第一张图片。保存图像时，我希望它保存隐藏的图像而不是显示的图像。

I am trying to put 2 images on top of each other. I am hiding the 2nd image and show the 1st image. when the image is saved, i want it to save the hidden image instead of the shown image.

<div style="width:180px;height:186px;">
<img src="1.jpg" width="180" height="186" alt="" style="z-index:-1;position:absolute;" />
<img src="2.gif" width="180" height="186" alt="My Kids"" style="z-index:-1;position:absolute; visibility:hidden" />
</div>

这可能吗？



谢谢

Is that possible?

The context menu and the 'Save image as' entry in it belongs to the browser and there is no event associated to it in JavaScript, that you can handle and change...
You may change the whole context menu, by replacing it with your own, but in that case you should have to write some JavaScript to handle the save-to-disk part...but JavaScript can not access the disk...
You may open the right image (the one to save) in a new window, but in that case you are into a two-step saving, and that is not too user friendly...
And if you do all this wired 'solutions' you still can't prevent from end user to take whatever picture he wants...
I would advise you to think about your problem (and maybe share with us) alone different lines, as this and your previous post will lead nowhere really...
