Description
|
cssSrc
|
Optional
|
scriptsrc/ajax
|
Specifies the URL, relative to the web root,
of the directory that contains the CSS files used by ColdFusion
AJAX features, with the exception of the rich text editor. This
directory must have the same directory structure, and contain the
same CSS files, and image files required by the CSS files, as the web_root/CFIDE/scripts/ajax/resources
directory.
This attribute lets you create different custom
styles for ColdFusion AJAX controls in different applications.
|
params
|
Optional
|
|
This attribute allows you to specify parameters
for the CFM page.
Currently, the only parameter that you
can specify is googlemapkey. You can specify the googlemapkey as
follows:
<cfajaximport params=#{googlemapkey="Map API Key"}#>
|
scriptSrc
|
Optional
|
scriptsrc setting
in the Administrator;
default
path is /CFIDE/scripts/
|
Specifies the URL, relative to the web root,
of the directory that contains the client-side script files used
by ColdFusion. This directory includes the JavaScript files and
the default location of the CSS files used for all AJAX features.
If
you use this attribute, the cfajaximport tag must
precede all other ColdFusion AJAX tags on the page; that is, all
tags that rely on the scripts.
You can have only one scriptsrc attribute
on a page, in a cfajaximport tag or a cfform tag.
You can use a scriptsrc attribute in a cfajaximport tag to
apply its value to all forms on a page.
|
tags
|
Optional
|
|
A comma-delimited list of tags or tag-attribute
combinations for which to import the supporting JavaScript files
on this page.
If you use this attribute, it must specify all
ColdFusion AJAX tags that you use on the page and on any pages specified
in tag source attributes.
For a list of valid
attribute values and their purposes, see Usage.

Using the scriptsrc and cssSrc attributesThe scriptsrc attribute
is useful if the JavaScript files are not in the default location.
This attribute is required in some hosting environments and configurations
that block access to the /CFIDE directory.
The default scriptsrc value
is determined by the Default CFFORM ScriptSrc Directory setting
on the Server Settings > Settings page of the ColdFusion Administrator.
For cfform tags, the tag’s scriptsrc attribute
takes precedence over this attribute.
You can use this attribute
only if the cfajaximport tag is on a top-level
page; that is, a page that the client directly requests. You cannot
use it, for example, on a page that is specified in a cfwindow tag source attribute.
When
you use the cfajaximport tag with a scriptsrc attribute,
the specified directory must have the same structure as the /CFIDE/scripts
directory. For example, if you specify scriptsrc="/resources/myScripts",
the JavaScript files used by AJAX must be in the /resources/myScripts/ajax
directory.
This attribute specifies the folder that contains
the ColdFusion client-side files for all subsequent tags on the
current page, not just for AJAX-based tags. Therefore, the directory
tree must include all ColdFusion client-side files used by those
tags. For example, if a cfform tag on the page
is in Flash or applet format, include the CF_RunActiveContent.js
file in the directory specified by the scriptsrc attribute.
You
use the cssSrc attribute to specify the location
of the CSS files required by ColdFusion AJAX features. This attribute
overrides the scriptsrc/ajax/resources directory for the
current page. Therefore, if all pages that use a custom scriptsrc directory
also use a custom cssSrc directory, you do not
have to include the ColdFusion AJAX CSS files in the scriptsrc directory
tree.
Using the tags attribute or no attributeIf you do not use the cfajaximport tag
on a page that contains ColdFusion tags with AJAX UI features, ColdFusion
correctly imports the required JavaScript files in most cases. Use
this tag to explicitly import JavaScript files in these cases:
If you use a ColdFusion AJAX JavaScript function, such as ColdFusion.navigate, ColdFusion.Ajax.submitForm,
or ColdFusion.Log.info on a
page that does not otherwise import any AJAX JavaScript functions,
use the cfajaximport tag with no attribute to import
the base JavaScript functions only. For example, use this tag on
a page that does not include any ColdFusion AJAX-based tags,
If the following conditions are true:
You use
any source attributes in cflayoutarea, cfpod or cfwindow tags,
or bind attribute in cfdiv tag.
The file that the source or bind attribute
specifies has any of the tags listed in the following table.
You do not use each of the listed tags on the top-level
page.
If
these conditions are true, the top-level page must use the cfajaximport tag
with a tags attribute that specifies the tags that
only the other pages use. Otherwise, ColdFusion cannot identify
that it will be using the tags and does not import the necessary
JavaScript files.
You can specify any or all the
following tag attribute values:

for AJAX features and for the AJAX CSS files. It also imports all JavaScript
files used for cftree, and cftooltip.

scriptsrc="/collegeApp/ajaxScripts"
tags="cftooltip, cfwindow">
