posLeft Property

Sets or retrieves the left position of the object in the units specified by the cascading style sheets (CSS) left attribute.

Syntax

HTML N/A

Scripting object.style.posLeft [ = iLeft ]

HTML	N/A
Scripting	object.style.posLeft [ = iLeft ]

Possible Values

iLeft Integer that specifies any valid floating-point number that uses the same length units as the left attribute.

The property is read/write with no default value.
Expressions can be used in place of the preceding value(s), as of Microsoft® Internet Explorer 5. For more information, see dynamic properties.

Remarks

This property reflects the value of the CSS left attribute for positioned items. This property always returns 0 for nonpositioned items, because "left" has meaning only when the object is positioned. Use the offsetLeft property to calculate actual positions within the document area.

Setting this property changes the value of the left position, but leaves the units designator for the property unchanged.

Unlike the left property, the posLeft property value is a floating-point number, not a string.

For more information about how to access the dimension and location of elements on the page through the document object model, see measuring element dimension and location.

Example

This example uses the posLeft property to move the first IMG object left by 10 units.

Sample Code
<SCRIPT LANGUAGE="JScript">
document.all.tags("IMG").item(0).style.posLeft -= 10;
</SCRIPT>
This example uses a timer to move the posLeft property in increments of 10.

Sample Code
<SCRIPT LANGUAGE="JScript">
function moveThis()
{
:
    if (sphere.style.posLeft<900) {
        sphere.style.posTop += 2;
        sphere.style.posLeft += 2;
        window.setTimeout("moveThis();", 1);
        }
}
:
</SCRIPT>
