Question

I have a control:

<input id="trigger_update_submit" type="image" src="images/green_flag.png" alt="" name="set_this" value="uu" />

This control is activated by some javascript:

document.getElementById('trigger_update_submit').click();

The problem is that the value of “uu” is not posted to the receiving page. All other controls work as they should but they are actually clicked on by the user.

I have a work around but I would rather use this method since I have other submit controls and would like to use the same handler.

Thanks!

Edit: Just want to mention that the .click() event fires as part of a larger JS function which is called by a different button so I cant use the onClick event of the trigger_update_submit control.

Answer 1

input type=image expects to send the x,y coordinates of your click within the image. If you “click” it via JavaScript it cannot find your mouse coordinates since the mouse is outside the image.
