<Incorporating HTML form tags and attributes
In HTML format, the cfform tag lets you incorporate the following standard HTML elements.
They are not available in Flash format:
• Standard HTML form tag attributes and values. The attributes and values are included in the
form tag that cfform outputs in the page. For example, you can use form tag attributes like
target or onMouseOver with cfform.
• HTML tags that can ordinarily be put within the HTML form tag. For example, you can use
the HTML
input tag to create a submit button in a cfform, without the other features of
cfinput:
<cfform>
<input type = "Submit" value = " update... ">
</cfform>
