clientY参数属性

DHTML文档教程

Sets or retrieves the y-coordinate of the mouse pointer's position relative to the client area of the window, excluding window decorations and scroll bars.

dhtml语法

event.clientY [ = iYPos ]

DHTML可能的值

iYPos Integer that specifies or receives the y-coordinate, in pixels.
The property is read/write. The property has no default value.
Expressions can be used in place of the preceding value(s), as of Microsoft® Internet Explorer 5. For more information, see about dynamic properties.

remarks

the property is read-only in microsoft® internet explorer 4.0, and read/write in internet explorer 5 and later.
because the clienty property returns a value relative to the client, you can add the value of the scrolltop property to determine the distance of the y-coordinate from the edge of the body element.
within a viewlink, the client area begins at the edge of the master element.

DHTML代码范例

This example uses the clientY property to determine the mouse position relative to the window. The status window shows the mouse position at all times.
<SCRIPT>
function clientCoords()
{
var offsetInfo = ""
clientInfo = "The x coordinate is: " + window.event.clientX + "\r"
clientInfo += "The y coordinate is: " + window.event.clientY + "\r"
alert(clientInfo);
}
</SCRIPT>
</HEAD>
<BODY onmousemove="window.status = 'X=' + this.clientX + ' Y=' +
this.clientY"
ondblclick="clientCoords()">
