点击图片，获取坐标 [英] Click an image, get coordinates

问题描述

我知道这是可以做到的，我甚至对如何做到这一点有一个模糊的想法，但它停止了模糊。

我有一个标准的HTML图像标记其中有一个图像，大小为100×100像素。我希望人们能够点击图像，并将它们点击的X和Y传递给一个函数。

坐标需要相对于图像

预先感谢您的帮助。 解决方案

我认为你在谈论：

 < input id =infotype =image> 
  

提交时，x和y坐标的表单值基于输入元素id（ info.x 和 info.y 在这种情况下）。

http：//www.w3。 org / TR / REC-html40 / interact / forms.html＃h-17.4.1

I know it can be done and I even have a vague idea of how to do it but it stops at being vague.

I have a standard HTML image tag with an image in it, 100 by 100 pixels in size. I want people to be able to click the image and for that to pass the X and Y that they click into a function.

The coordinates need to be relative to the image top and left.

Thank you in advance for any help.

解决方案

I think you're talking about:

<input id="info" type="image">

When submitted, there are form values for the x and y coordinate based on the input element id (info.x and info.y in this case).
