In our experiments with jQuery Mobile, specifically when applying jQuery Mobile to an existing website, we've encountered one error more than any other. That error is the l.data("page") undefined<\/em><\/p>\n

It appears that, due to the way jQuery Mobile handles page loading (via AJAX), redirects within your code throw a wrench into the works.<\/p>\n

For example, if after submitting a form, you automatically redirect the user to a "Thank You" page, jQuery Mobile is unaware of this action and may throw the error above.<\/p>\n

One way around this is to avoid the redirect, and simply display a "Thank You" message within your processing script.<\/p>\n

To illustrate this in ColdFusion, you would replace the following code:<\/p>\n

<cflocation url="thank-you.cfm">
\n\t<\/code><\/p>\n

with<\/p>\n

<p>Thank you for your request.<\/p>
\n\t<a href="\/">Return Home<\/a>
\n\t<\/code><\/p>\n

\n\tWhich allows jQuery Mobile to continue loading pages via AJAX.<\/p>\n","protected":false},"excerpt":{"rendered":"
