setAttribute Method

Sets the value of the specified attribute.

dhtml语法

object.setAttribute(sName, vValue [, iFlags])

Parameters

sName Required. Stringthat specifies the name of the attribute.
vValue Required. Variant that specifies the string, number, or Boolean to assign to the attribute.
iFlags Optional. Integerthat specifies one the following flags:
0 When the attribute is set, it overwrites any attributes with the same name, regardless of their case.
1 Default. The case of the attribute that you set is respected when it is set on the object.

Return Value

No return value.

Remarks

If the specified attribute is not already present, the setAttribute method adds the attribute to the object and sets the value.
Be careful when spelling attribute names. If you set iFlags to 1 and the sName parameter does not have the same uppercase and lowercase letters as the attribute, a new attribute is created for the object.
If two or more attributes have the same name, differing only in case, and iFlags is set to 0, this method assigns values only to the first attribute created with this name. All other attributes of the same name are ignored.
When setting the CLASS attribute using this method, set the sName to be "className", which is the corresponding Dynamic HTML（动态HTML，即DHTML） property.
