Area coords Property
Area Object
Definition and Usage
The coords property sets or returns the value of the coords attribute of an area.
The coords attribute specifies the x and y coordinates of an area.
Tip: The coordinates of the top-left corner of an area are 0,0.
Syntax
areaObject.coords=value
The coords property can have one of the following values:
| Value | Description |
|---|---|
| x1,y1,x2,y2 | If the shape attribute is set to "rect", it specifies the coordinates of the top-left corner and the bottom-right corner of the rectangle |
| x,y,radius | If the shape attribute is set to "circle", it specifies the coordinates of the circle center and the radius |
| x1,y1,x2,y2,..,xn,yn | If the shape attribute is set to "poly", it specifies the coordinates of the edges of the polygon. If the first and last coordinate pairs are not the same, the browser must add the last coordinate pair to close the polygon |

The coords property is supported in all major browsers.
