Re^2: How to make ajax requests in Dancer2

Are you referring to comparing what firebug shows or the rendered pages?

I probably should have explained that the php app is not a duplication of this perl app. The javascript is a direct copy of what I'm using in the php app with the only difference being the url assignment. On the php side, firebug is showing the same type of successful results i.e., status 200, content-type and length are what's expected and the Response and HTML sections are showing the correct/expected results.

The only difference I see is in the final rendered page where the document.getElementById('folder').innerHTML = xmlHttpObj.responseText; is being executed in the php app, but not in the perl app. I'm not seeing any errors or anything else in firebug that would account for this, but I have to admit that I don't full understand some of the info it's providing.

My knowledge of javascript and ajax/jquery is very limited which makes troubleshooting that portion of the app frustrating.

If the error only occurs with the Perl side, then there must be a difference in what Perl returns when compared with what PHP returns. Inspect both parts until you find the difference. Consider maybe returning a static JSON file instead of using Perl to find out what the Javascript breaks on.	[reply]

Can you give a simple/short JSON example based on my posted code? I've never used JSON.	[reply]

I don't have your working PHP code, and I don't have the time to do your legwork, sorry. Have you considered visiting the PHP JSON URL with your browser, and then comparing the result you get there with the result you get when you visit the Perl JSON URL with your browser? I guess that for the Perl version, `/p_details` is the one you want. But I also see that, if I understand the Dancer documentation correctly, that URL won't return the appropriate `application/json` (or whatever is needed) content type. You will want to send the same headers from Perl that you send from your PHP script. You will also send the same JSON from Perl that you send from your PHP script. The template you show for (supposedly) `/p_details` is not JSON. Ajax mostly wants JSON.	[reply] [d/l] [select]
