DHTML可能的值
sPosition Variant that specifies or receives one of the following values:
auto Default. Position is determined by the regular HTML layout of the page. length Floating-point number, followed by an absolute units designator (cm, mm, in, pt, pc, or px) or a relative units designator (em or ex). For more information about the supported length units, see css length units reference. percentage Integer, followed by a percent sign (%). The value is a percentage of the width of the parent object. The property is read/write for all objects except the following, for which it is read-only: currentStyle. The property has a default value of auto. The Cascading Style Sheets (CSS) attribute is not inherited.
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
only use the right attribute when the position attribute is set; otherwise, the value of the right attribute is ignored.
you cannot use the right property in script to calculate the position of the object in the document, because the value of the right property is a string. instead, use the pixelright property or the posright property.
for more information about how to access the dimension and location of objects on the page through the dhtml object model, see measuring element dimension and location.
