Handling AJAX Responses

The following attributes affect the handling of all ajax responses.

Attribute

Default Value

Description

parseContent

true

When true, Dojo will parse the response into an XHTML Document Object and traverse the nodes searching for Dojo Widget markup. The parse and traversal is performed prior to inserting the nodes of the document into the DOM. This attribute must be enabled to nest Dojo widgets (dojo tags) within responses. Note that there is significant performance overhead creating and parsing the document so switch this feature off when not required. Note also that the response must be valid XHTML for cross-browser support.

separateScripts

true

When true, Dojo will extract the <script> tags from the response, concatenate the extracted code into one block, create a new Function whose body is the extracted code and immediately invoke the function. The invocation is performed after the DOM has been updated with the XHTML. The function is executed within the scope of the widget (that is, the this variable points to the widget instance)

executeScripts

false

When true, Dojo will extract the <script> tags from the response, concatenate the extracted code into one block and immediately perform an eval() on that code (run it). The eval() is performed after the DOM has been updated. Note that the separateScripts takes precedence over executeScripts. Enable this feature when your response contains TRUSTED inline javascript.

Note

It's common that the updated DOM will not include <script> even though the inline code may have been executed.

Topics

Most of the AJAX tags use Dojo topics for event notification and communication between them, to learn about topics visit Dojo's documentation
