Обсуждение: Getting Image coordinates when mouse is clicked on the image and storing it in a variable

  Hello,
  Is there any way to get the coordinates value, when an image is clicked.
Say I have created an image link using "mapedit".Instead of linking to
any URL, I want to  link to a php file, which returns a value. This value
should be stored in a file against the corresponding coordinate of the
image.
    I.e when a mouse is clicked on a image, its coordinates value should
be stored in a variable and the corresponding function should be called
which returns a variable. Both these values should be stored in a
file.

Regards
Arun

If I understand you correctly, you simply want your script to know the exact
coordinates of the click. You could use JavaScript, I am pretty sure, or a
less elegant solution is use an INPUT field type IMAGE. If this type of form
field s give a name, the clicked coordinates are sent as fields "NAME.x" and
"NAME.y" (where NAME is the name of the field).

there's a much easier way, just make a form like this:

<form name="test">
<input type="image" name="anna" src="anicole.gif">
</form>

and when the user clicks on the image, you'll get two vars called:

anna.x and anna.y

You know what they'll contain... :-)
