All of the following methods are specific to Internet Explorer 4.0's Dynamic HTML object model. None are supported by Netscape or any previous versions of Internet Explorer
click method can be used to 'click' a referenced object through scripting, forcing an
onClick event for the particular element. For example, click the top of the following two links and it 'clicks' the second link:
contains method can be used to determine whether the referenced element totally encloses (contains) another element. For example:
<P ID="para1">Some <STRONG ID="str1">strong, bold</STRONG> text</P>
alert (para1.contains(str1)) would return true.
getAttribute method can be used to retrieve the value of a specific attribute for the referenced element. For example:
would retrieve the value of the
BGCOLOR attribute of the element whose
false argument is a boolean value (i.e. true or false), specifying whether or not the search to find the attribute is case-sensitive or not. 'True' means that the attribute case must match that give in the attribute value, for the
getAttribute method to work - the default value is 'false'. Depending on the value of the attribute, the
getAttribute method returns either a string, a number, or a variant.
insertAdjacentHTML method can be used to insert a new HTML element into the document, without removing a previous one (as manipulation of the
insertAdjacentHTML places the string specified in the second argument, at the position specified in the first argument. For example:
document.all.tags("P").item(1).insertAdjacentHTML("BeforeBegin", "<P>Here's a new paragraph")
<P>Here's a new paragraph before the second paragraph in the document. The possible values for the positioning are:
insertAdjacentText method is essentially identical to the
insertAdjacentHTML method, except that it inserts literal text, regardless of the strings actual content. It takes the same argument set - i.e.
(string, position) where
position can be one of the four values mentioned above.
removeAttribute can be used to remove an attribute and its associated value from the referenced element. This is subtly different to dynamically setting the attribute property value to nothing. Using the
removeAttribute value forces removal of the attribute, as if it had never been set in the first place. The
removeAttribute method returns a boolean (i.e. true or false) value depending on whether the attribute was successfully removed or not. Its optional second argument is a boolean value, which specifies whether to use a case-sensitive search to locate the attribute to remove. For example:
bKilldataSrc=dataTable.removeAttribute "DATASRC", "false"
would make the
bKilldataSrc true or false, depending on whether the
DATASRC attribute was removed from the element referenced by
dataTable. The search is case-insensitive. The default value for the case-sensitivity argument, if none is given, is 'true'.
scrollIntoView method can be used to force the current viewing window to scroll to a referenced element object. It accepts a boolean argument (true or false) which determines whether the window should be scrolled so that the referenced element object is at the top (true) or bottom (false) of the window. For example, the button below will scroll the links given in the
click example, so that they're at the bottom of the viewing window.
Like the other
setAttribute can be used to set the value of a specific attribute for a referenced element. For example:
MyTable.setAttribute "DATASRC", "#Comp1", true
would set the
DATASRC attribute to
#Comp1 for the element referenced by
MyTable. Basically, the first and second arguments for the method specify the attribute and its value to be set, with the third argument being 'true' or 'false', specifying whether case sensitive setting of the attribute is used or not. If this is set to 'true' (the default) and the attribute name you specify for the referenced element has a different case than any existing setting of that attribute, then a new attribute will be created, with the value specified in the value argument.

is no longer needed, as of netscape 6.5, mozilla 1.7, and firefox 1.0. It just took a bit for netscape to recover from the AOL/Sun nightmare. There still may be subtle differences in how layers are displayed but there are other sites you can link to for that.
PS a 'last updated' time-date stamp at the bottom would be helpful.
